Staff Report Overview
This staff report contains one application for consideration by the PZC: LCE20001: Location,
Character & Extent for a proposed expansion of the Eagle River Water and Sanitation District
(District) Waste Water Treatment Facility (WWTF).
Summary of Request
Expansion of the plant is required to comply with new State of Colorado effluent standards and is
planned as part of a $150 million Capital Improvement Plan. As described in more detail below,
proposed expansion of public facilities requires a Location Character & Extent (LCE) application
process as a basis to judge the project. This application process can be interpreted as a development
plan application with different criteria, mandated by the State. While not the basis of the decision,
staff also included the design review criteria found in typical development applications to provide
additional points of clarity.
Background
As outlined on page 7 of the application, the District has put lots of time and thought into the
decision to expand this facility. A new building will house new systems (Attachment A, page
18) to further treat waste water before being released back into the Eagle River. The best
renderings showing the existing and proposed modifications are found on page 50 of the
application. Construction is expected to last between 32-36 months, with commencement
planned for Spring 2020. Please refer to the Attachment K link for a detailed schedule.
Location Character Extent
The LCE review process is used for the review of proposed public facilities or uses as provided
by Section 31-23-209 of the Colorado Revised Statue
Process
The Planning and Zoning Commission is requested to take formal action on this LCE Public
Hearing. Town Council will then review the 1041 Permit Application (for projects in an area of state
interest) and use the decision from this LCE as a basis for final approval before a building permit will
be issued. The 1041 application is slated for Town Council review on February 25 and March 10 if
needed.
Waste Water Treatment Facility Expansion Application – February 4, 2020
Property Description
Tract N and O are located
between the Eagle River
and the railroad corridor,
with access to West Beaver
Creek Boulevard from
Millie’s Lane. The site is
very visible from
Nottingham Park and
Highway 6 and gives this
area an industrial feel. The
site is 100% disturbed with
a combination of below and
above ground structures,
surface parking, and storage
areas. The properties
include a public easement
for the Eagle Valley
Regional trail, which runs the length of the southern property lines.
7.16.150 Location , Character & Extent Application
“It is the intent of this Section to conform to the provisions of Section 31-23-209, C.R.S., to
define the factors to be considered in the ‘Location, Character and Extent’ process and to prescribe
procedures for the orderly consideration of location , character and extent applications in order to
effectuate the purposes of the state statute.
(a) Applicability. No road, park, public way, ground or space, no public building or structure
and no major facility of a public utility shall be constructed or authorized, and no building
permit for the same shall be issued, in the Town unless and until the proposed location, character
and extent thereof has been submitted to and approved by the Town. Routine extensions of public
utility lines and minor modifications to existing facilities shall not be subject to this procedure.”
The LCE process is intended to verify that public improvements for activities, primarily funded
by taxes, are of benefit to the public and in compliance with Town standards and the local
Comprehensive Plan.
Development Standards Analysis
Allowed Use and Density: The subject property is zoned PF, which is intended for “uses such as
community centers, police and fire stations and governmental facilities.”
Lot Coverage, Setback and Easements: With 36.4% lot coverage, the proposed structures are
compliant with the applicable dimensional standards of the PF District. The project crosses an
internal lot line and is subject to a Minor Subdivision Application to comply with setbacks. A utility
easement servicing the old barn will likely be abandoned in this process as well.
Building Height: The maximum building height permitted for this property is 40 feet. The
proposal will not increase building height and new structures will match existing rooflines and
adjacent structures. An Improvement Location Certificate is will verify compliance at both
foundation and framing inspections.
Waste Water Treatment Facility Expansion Application – February 4, 2020
Parking: The applicant proposes to have only the office space considered as the applicable Gross
Floor Area (GFA). While the development proposes 84,194 total square feet of GFA, the office area
is 7,652 square feet, requiring 32 spaces under the “Government services, offices, and facilities” use
group(336 spaces for the whole GFA). The “general industrial uses unless otherwise stated” use
group requires 1 parking space per 800 square feet GFA (106 spaces for the entire project, 10 for the
office space). The proposal includes 48 parking spaces.
Exterior Lighting: The Applicant is proposing to use all dark sky compliant lights for new
fixtures (Exhibit D). However, staff believes there are existing lights on the structure that do not meet
the dark sky ordinance, which may remain after construction. This application should be an
opportunity to confirm that all exterior lights meet the ordinance, and staff suggests a combination of
lighting types that will be compliant with the Dark Sky Ordinance and meet the definition of "full
cutoff ' per code.
Building Design: The proposed design is best described as boxy and industrial. Development code
requires recesses and projections, changes in texture and color, or vertical accents to break up linear
aspects of a building, which are minimally present.
Waste Water Treatment Facility Expansion Application – February 4, 2020
Colors and Materials: The building is proposed to be painted three colors, two grays and a brown
color (Attachment A, page 50 and Exhibit B, sheet 05A05). Existing building elements will be
repaired as needed, with all existing building elements repainted to match existing colors. This
process is expected to provide a more uniform look to the site.
Roof Material and Pitch: New structures are designed to match existing rooflines, which are mostly
flat. The proposal builds a new concrete superstructure over the existing grass covered roof of the
aeration basin tank that is now a grass covered roof. The Development Code requires roofline
modulation, which is minimally present.
Screening: The proposal includes three (3) tall Strobic Fans (Attachment A, page 52) which propel
odorous air into the sky. From Nottingham Park, they will be the most visually impactful elements of
the design. Development Code requires screening of mechanical equipment with a parapet wall or
similar feature. Staff suggests, at a minimum, that the fan stacks be painted either black or the darkest
color available from the palette. PZC could work with the applicant to investigate alternative odor
reduction methods for the aeration basins or seek additional screening of the equipment.
Landscaping: The PF zone district does not have a
minimum landscaped area requirement and is therefore
exempt from this portion of the review. The landscaping
plan essentially calls for native seed for any disturbed areas.
Staff is aware that the District is working with the adjacent
Liftview Condominiums complex to possibly replant trees
removed on the western edge (pictured right, and Exhibit B,
sheet 05C16) and encourages a creative solution. Currently,
there is approximately 140 feet and a mature set of trees
between the secondary clarifier building and the nearest
condo. With the addition of the west secondary clarifier and
the aeration basin structure, a continuous blank wall roughly
60 feet from the condo is proposed.
The old barn location will be used for lay-down during
construction, and a swath of trees in the area is proposed to be removed and resurfaced with asphalt.
An auto path around the property is permanently proposed for the area. Staff suggests that appropriate
areas on either side of the road and along the exterior of the fence line be re-planted with trees. This
would minimize the loss of trees (per the Comprehensive Plan criteria, below) and provide appropriate
screening from the Eagle Valley Trail. Alternatively, a revision that preserves or enhances trees on
the southern side would be preferred. Overall, the site will become slightly more impervious but
improved stormwater quality controls will offset the difference.
Irrigation: The native seed is proposed to be temporarily irrigated until established.
Fencing: To mitigate the loss of screening trees, a 10’ tall architectural fence is proposed on the
western property line adjacent to the Liftview Condos. Plan Sheet 05A12 (Exhibit B) contains a
landscape plan and fence detail. Staff would appreciate a photo of the proposed fence for staff
approval. Code allows a maximum of 5 feet fences, however, there is an exception for unique
security purposes.
Waste Water Treatment Facility Expansion Application – February 4, 2020
Review Criteria
§7.16.150(d) Location, Character & Extent Review Criteria
(1) Evidence of substantial compliance with the purpose of this Development Code;
Staff Response: The application was found in conformance with the purposes of the Avon
Development Code (Sec. 7.04.030). Specifically, select purposes state:
(g) Promote sufficient, economical and high-quality provision of all public services and public
facilities, including but not limited to water, sewage, schools, libraries, police, parks, recreation, open
space and medical facilities;
(j) Sustain water sources by maintaining the natural watershed, preventing accelerated erosion,
reducing runoff and consequent sedimentation, eliminating pollutants introduced directly into streams
and enhancing public access to recreational water sources;
(m) Achieve innovation and advancement in design of the built environment to improve efficiency,
reduce energy consumption, reduce emission of pollutants, reduce consumption of non-renewable
natural resources and attain sustainability;
(p) Promote the health, safety and welfare of the Avon community.
(2) Consistency with the Avon Comprehensive Plan;
Staff Response: The application was reviewed in accordance with the applicable sections of the
Avon Comprehensive Plan (linked below) and has been determined by Staff to be generally
compliant with all relevant purposes, goals and policies contained therein. Selected components of
the Plan are below:
Goal G.1: Protect Avon’s unique natural setting and its open spaces.
Policy G.1.4: Minimize and mitigate potential development impacts to wildlife and watersheds.
Policy G.1.4: Locate parking areas, trash containers, loading, and service areas so they are screened
or buffered to minimize impacts on the Eagle River or surrounding uses.
The properties are in the Riverfront District, with select Planning Principles cited below:
• Improve and enhance connections to the linear park along the river, the Eagle Valley Trail, Town
Center, Beaver Creek, and Nottingham Park.
• Orient buildings to capitalize on the Eagle River as an amenity. Use sensitive site planning, architectural
detailing, articulation, and appropriate setbacks, color, screening, and scale of structure to preserve the
character of the river and its associated natural habitat.
• Limit building height to a scale that is subordinate to Town Center and compatible with the river
environment. Buildings should be designed to step down in height as they near the river and in
response to the natural topography.
• Adhere to the Eagle River Watershed Management Plan for river setbacks and best practices for
development in proximity to the river.
• Locate parking areas and building services away from the river and reduce their impact on the river
corridor.
• Minimize the loss of trees and impact to the riparian area while achieving urban design goals.
Staff feels that the additional landscaping considerations mentioned above are needed to achieve
consistency with the Comprehensive Plan.
Waste Water Treatment Facility Expansion Application – February 4, 2020
(3) Physical suitability of the land for the public way, place, structure, facility or utility;
Staff Response: The proposed facility expansion will be added to an existing facility on the site.
PZC should carefully weigh if this plan is physically suited for the structure.
(4) Compatibility with surrounding land uses; and
Staff Response: The facility is correctly zoned and adequately served by existing infrastructure to
accommodate the treatment plan expansion. Existing nearby uses are either benefiting from the
diminished odors (Attachment A, page 41), or properly buffered from the site. Tract G, the river, and
Highway 6 all provide significant buffers to much of the surrounding land uses. Nottingham Park
itself will be impacted by diminished views with more visible flat roofs, piping, and hardscape.
(5) Adequate mitigation of adverse impact on nearby properties or neighborhoods,
including but not limited to traffic, noise, odors, vibrations and property values.
Staff Response: As mentioned, the final facility will have some impact to residential properties in
the area as well as Nottingham Park. Odor and noise impacts were studied and demonstrate negative
impacts (Attachment A, page 41 and 45).
Construction impacts are proposed to be addressed in an ongoing manner as the nature of the project
changes (Exhibit A, page 31). Construction related traffic and noise, and 24 months of crane
operation will impact the vicinity. The District plans to conduct only necessary operations at the plant
during construction, relocate service trucks, and hold meetings at different locations for the duration
of the project.
Avon Development Code Design Standards
While these standards are not called out for LCE review, staff is including them to anchor the
application in terms that the PZC is accustomed to. PZC is encouraged to review these criteria but not
use them for the basis for their decision.
§7.16.080(f), Development Plan
(1) Evidence of substantial compliance with the purpose of the Development Code as
specified in §7.04.030, Purposes;
Staff Response: See above.
(2) Evidence of substantial compliance with the §7.16.090, Design Review.
Staff Response: Staff finds this plan compliant with the Design Review criteria listed in the
Development Code. The Design Review section seeks high quality development and structures that
are visually harmonious with their site and surrounding vicinity. Conformance with this code section
is discussed below in response to the Design Review criteria.
(3) Consistency with the Avon Comprehensive Plan;
Staff Response: See above.
(4) Consistency with any previously approved and not revoked subdivision plat, planned
development, or any other precedent plan or land use approval for the property as
applicable;
Staff Response: Staff suggests a condition to approval modifying the lot lines through a Minor
Subdivision Application.
Waste Water Treatment Facility Expansion Application – February 4, 2020
(5) Compliance with all applicable development and design standards set forth in this
Code, including but not limited to the provisions in Chapter 7.20, Zone Districts
and Official Zoning Map, Chapter 7.24, Use Regulations, and Chapter 7.28,
Development Standards; and
Staff Response: The LCE application does not specifically address design standards, however, staff
encourages a discussion regarding the building design, screening, landscaping, and fencing on the
property.
(6) That the development can be adequately served by city services including but not
limited to roads, water, wastewater, fire protection, and emergency medical
services.
Staff Response: The location of the proposed facility is capable of being served by existing
utilities and services.
§7.16.090(f), Design Review
(1) The design relates the development to the character of the surrounding community;
or, where redevelopment is anticipated, relates the development to the character of
Avon as a whole;
Staff Response: The proposed mass and scale of the structure is in part a result, and related to, the
development decisions made in Avon and surrounding mountain communities.
(2) The design relates the development to the character of the surrounding community;
or, where redevelopment is anticipated, relates the development to the character of
Avon as a whole;
Staff Response: Besides previously discussed items, the design is compliant with the development
and design standards contained in the Development Code.
(3) The design reflects the long range goals and design criteria from the Avon
Comprehensive Plan and other applicable, adopted plan documents.
Staff Response: Applicable adopted plans include the Avon Comprehensive Plan. Except where
mentioned, t he design is considerate of these plans.

SECTION I: Introduction and Overview
Background
The Eagle River Water and Sanitation District (District) owns, operates, and
manages an integrated water supply system that serves up to 55,000 residents
and visitors in Eagle County. The District obtains source water from the Eagle
River and Gore Creek. The District also owns and operates wastewater treatment
facilities (WWTFs) in the towns of Vail and Avon and unincorporated Edwards that
discharge to Gore Creek and Eagle River. The WWTFs are interconnected via an
integrated collection system. The upstream facilities can share flows and loads to
the downstream facilities, which allows significant operational flexibility and risk
reduction.
The three WWTFs must comply with discharge permits that regulate effluent
quality. The Colorado Discharge Permit System (CDPS) permits are issued and
enforced by the Water Quality Control Division (WQCD) of the Colorado
Department of Public Health and Environment (CDPHE). In 2012, the Water
Quality Control Commission (WQCC) adopted nutrient regulations known as
Regulation 85 that require the District to alter the treatment processes and
operations of our facilities to reduce the levels of phosphorus and nitrogen
(nutrients) in effluent discharged to Gore Creek and the Eagle River. A copy of
Regulation 85 is included as Attachment R. The nutrient regulations are intended
to benefit the water quality and biological health of the receiving water and will
require significant WWTF capital investment. Improvement to source water quality
will also benefit downstream drinking water facilities.
The District has long supported the initiative for increasing nutrient removal at its
facilities and has been optimizing operations and implementing capital projects
over the last several years to improve instream water quality. Staff has made
outstanding progress in that regard, but significant capital improvements are still
needed to consistently meet future limits and the anticipated growth within the
service area.
In 2017, the District developed a Nutrient Management Plan and updated its
Wastewater Facilities Master Plan, known as the 2017 Master Plan Update (MPU).
This helped the District better understand the capital needs and determine the
most efficient and effective way to meet nutrient regulations at its three wastewater
treatment facilities. The District’s goal was to develop a plan that benefits instream
water quality, while balancing the availability of resources with the financial impact
to ratepayers. To meet this goal, the District implemented an innovative planning
approach that considers how the facilities can best operate as a system, rather
than as individual facilities. As a result, the District leveraged the benefits realized
through integration of the three WWTFs – from process, financial, and regulatory
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 8
perspectives – to support decisions about where capital funds can be most cost-
effectively invested to meet future discharge permit requirements.
The result of these planning efforts is a 20-year Capital Improvements Plan (CIP)
with a total $150 million in projects estimated. District and CDPHE staff worked
closely to develop a Memorandum of Understanding (Attachment D) in which the
District received the needed assurances to immediately start the design and
construction of the nutrient upgrade project at Avon, and CDPHE sees meaningful
in-stream nutrient reductions in the near-term.
The first nutrient reduction capital project outlined in the Master Plan is at the Avon
WWTF (AWWTF). AWWTF has the highest hydraulic capacity of the District’s
three WWTFs, so reducing nutrients at the Avon WWTF first creates the greatest
environmental benefit in the near-term.

Avon Treatment Facility Modifications
The Avon WWTF was originally constructed in the 1960s and underwent numerous
expansions and improvements over the years, most recently, a major liquid-stream
improvement project in 2013 to upgrade and convert its secondary treatment
processes to a Modified Ludzack-Ettinger (MLE) process that reduces ammonia
(a form of nitrogen) concentrations in the effluent. The facility has an average daily
maximum month flow (ADMMF) permitted capacity of 4.3 million gallons per day
(MGD) and is fully compliant with current regulatory requirements. The Avon facility
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 9
currently removes nitrogen and phosphorus, but such removal must be increased
to consistently meet the more stringent effluent limits required by the new nutrient
regulations.
The proposed project will increase the organic treatment capacity of the facility
from 11,750 pounds of the five-day biological oxygen demand (BOD5) to 13,100
pounds of BOD5. BOD5 quantifies the oxygen demand of the wastewater and
determines the organic loading.
Most of the AWWTF will be modified for this project, either to construct process
improvements to meet the nutrient removal requirements or to address necessary
condition assessment projects (components of the facility that are at the end of
their useful life) recommended in the 2017 MPU. This includes:
• Preliminary treatment
• Primary treatment
• Primary effluent flow equalization
• Secondary treatment:
- Aeration basin modifications to operate in the anaerobic/anoxic/oxic
(A2O) process configuration for biological nitrogen and phosphorus removal
- Construction of a third secondary clarifier
• Chemical feed and storage
• Odor Control
Current facility performance and process modifications are documented at length
in the Carollo January 2019 Engineering Report and site plans (Attachments I and
C, respectively) and other attachments to this application.

Figure 2. Project overview.
The project goals are meeting tighter effluent limits; meeting future growth to a
twenty-year planning horizon; and providing significant flexibility for District-wide
wastewater treatment operations, as well on-site treatment redundancy and risk
reduction. To meet the goals, the design team chose an alternative that maximizes
the remaining unoccupied land within the site boundaries. The chosen alternative
will provide increased safety for the operational team, treatment access for process
control and maintenance, and significant operational flexibility – a necessity for
consistently meeting discharge permit requirements in a resort community where
flows and loads are extremely variable. The selected alternative also leverages the
interconnectedness of the three WWTFs, allowing the Avon facility to accept and
treat increased bypass flows from the Vail WWTF (VWWTF) during peak tourism
seasons. This will reduce the need for treatment expansion at VWWTF to meet a
peak demand observed for a few weeks out of the year (Christmas, New Years
and Fourth of July holidays).
In addition to the technical wastewater treatment design the design team was
mindful of the location of the facility in the heart of the Town of Avon. It is
challenging to operate a wastewater treatment facility in the existing location, with
residences, parks and trails directly adjacent to the site. Extreme care was taken
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 11
to evaluate decisions that may impact neighbors, recreational users, Nottingham
Park and the valley-wide viewshed. Significant planning efforts and studies
evaluated noise, odor, construction and the overall appearance of the facility. The
result of these efforts is a project that meets our community’s needs, returning
cleaner water to the Eagle River, accommodating for future growth, improving odor
treatment controls, improving onsite stormwater treatment, and improving the
overall site appearance.

Detailed Plans and Specifications
At this time of this application, Carollo, with input from the District and Moltz, has
advanced plans and specifications to a 90% level of completeness. After final reviews
and quality checks, the Issue for Construction set will be submitted to the Town of Avon
building department for review. The 90% plans and specifications are included in
Attachment C of this application.
Summary of Alternatives
The proposed Project was selected from a range of alternatives studied by the District in
2017. The alternatives evaluation reviewed capacity limitations, future effluent limits, and
treatment goals for each of the three wastewater facilities operated by the District. The
alternatives evaluation also assessed the use of bypass flows from VWWTF to AWWTF,
shared solids treatment at EWWTF, and CDPHE water quality requirements optimizing
treatment between all three wastewater facilities.

Figure 4. Avon WWTF existing liquid and solid stream simplified process flow diagram
(Carollo).
The following process alternatives were evaluated for the Avon WWTF in the 2017 MPU:
1. Conventional expansion of the secondary MLE treatment process with aeration
basins and secondary clarifiers; chemical addition for phosphorous removal.
2. Conversion and expansion of the existing MLE process into an A20
(anerobic/anoxic/oxic) process to integrate bio-P (biological phosphorus) removal.
3. Conversion of the existing MLE process into an A20 process to integrate bio-P
removal while limiting the secondary treatment plant expansion needs by providing
a chemical phosphorous removal backup.
4. Expansion of the secondary treatment process and conversion to an A2O process
with aeration basins and a secondary clarifier; additional basin volume such that
the AWWTF meets Regulation 85 nutrient limits while accepting influent bypass
flows from the VWWTF. Future regulatory compliance may include installation of
integrated fixed-film activated sludge (IFAS) media into a portion of the aeration
basins and conversion of the process into a 5-stage Bardenpho to integrate bio-P
removal while limiting additional expansion needs. Chemical addition is included
for backup chemical phosphorous removal.

(Carollo).
Alternative 4 was recommended by the project engineer and selected by the District. This
alternative includes a phased expansion approach that leverages the AWWTF site for
expansion while giving operational staff additional treatment capacity and flexibility to
operate differently in the long-term. This alternative allows the facility to accept increased
bypass flows from the VWWTF. The VWWTF experiences significant flow and load
increases during the peak tourism seasons (Christmas, New Years, and July 4th holidays);
bypassing these peaks during these times and treating the wastewater at the AWWTF for
a few weeks a year reduces the need for a significant expansion at the VWWTF, which
has a much more confined site.
The 2019 Avon WWTF Engineering Report (Attachment I), evaluates two main process
alternatives with several sub-alternatives. Evaluation was based on the following criteria:
- Compatibility with existing treatment processes;
- Compatibility with existing site constraints;
- Compatibility with seasonal variations in flows and loads due to the touristic
nature of the service area;
- Compatibility of meeting discharge limits;
- Compatibility with future treatment processes to meet future discharge limits; and,
- Capital and operation and maintenance costs.
After evaluation of the criteria, the anaerobic/anoxic/oxic (A2O) process alternative was
selected for AWWTF nutrient upgrade project. The A2O process alternative provides the
greatest flexibility for maximizing limited space and carbon input needed to accomplish
nitrogen and phosphorus removal. The process will maintain flexibility in the treatment
configuration to respond to seasonal operation demands. Effluent limits for total
phosphorus (TP) and total inorganic nitrogen (TIN) under Regulation 85 can be met by
implementing the proposed A2O process configuration at the AWWTF (Carollo, 2019).
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 19
The process bypass results in up to 0.9 million gallons per day (mgd) to the AWWTF
during the winter, peak treatment conditions. Facility operations under the proposed
configuration will have the flexibility to respond to times of critical flow. Bypass during the
spring peak flow conditions may not be necessary and will be determined by operating
conditions at the facilities. The project engineer evaluated impacts to water quality and
quantity of the selected alternative, and findings are summarized in the engineering
report.

applicant or owner expects to enter into in order to complete the project,
including intergovernmental agreements, if applicable.
In anticipation of meeting nutrient regulations at its three WWTFs, the District entered into
an agreement with the WQCD as set forth in the Memorandum of Understanding (MOU)
effective June 29, 2018. An Addendum to the MOU was executed by the District and
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 23
Division dated January 17, 2019 (Addendum). The MOU and Addendum are available in
Attachment D.
The following agreements relative to the Avon WWTF permit renewal are contained in the
MOU and Addendum:
The principal objective of the MOU was to allow the District to develop nutrient
controls at its three WWTFs in the most logical stepwise fashion and establish the
sequence and timing of improvements for that purpose;
The MOU and Addendum provide that improvements and other actions at the Avon
WWTF will be implemented as needed to meet or exceed Regulation 85 limits by
December 31, 2023, and before any nutrient control improvements are required to
be initiated at the Edwards and Vail WWTFs;
Consistent with the MOU, timing of the renewal of the District’s three discharge
permits will be synchronized; and
The Addendum sets forth more specifically the agreed upon nutrient compliance
schedule for each of the District’s WWTF permits and the associated Fact Sheet
language.
ERWSD has entered into contracts with Carollo Engineers for master planning and design
services related to this Project. Due to the complexity of design and construction of this
Project, the District Board of Directors approved delivery of this project with an alternative
delivery method, meaning that the contractor was competitively selected and contracted
with the District to provide design-phase services prior to 30% design. Therefore, the
District is currently operating under a Preconstruction Services contract with Moltz
Construction.
The District will enter into a construction contract, or multiple iterations of a construction
contract, with Moltz Construction, pending successful negotiation of a Guaranteed
Maximum Price (GMP) in approximately March 2020. No other agreements or
intergovernmental agreements are anticipated to complete the project.
7) The need for the proposed project in the Town, particularly in relation to
existing and/or permitted facilities, which perform a function similar or
identical to that of the proposed project.
The District’s Vail, Avon, and Edwards WWTFs are point source dischargers, tightly
regulated under the Clean Water Act (CWA). In accordance with the CWA, the EPA
authorized the State of Colorado to administer the Colorado Discharge Permit System
(CDPS) program to set limits on parameters that can be discharged from point sources
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 24
into Colorado waterbodies. The CDPS permit assigns water quality and antidegradation-
based effluent limitations to ensure that discharges to waters of the State meet or exceed
Colorado water quality standards. The District’s facilities are required to meet effluent
discharge permit limits designed to protect the physical, chemical, and biological integrity
of receiving waters in Gore Creek and the Eagle River.
The AWWTF discharges to Eagle River Segment 9a and operates under a CDPS
discharge permit (No. CO0024431) that became effective in December 2010. Both the
Avon and Edwards WWTFs’ CDPS permits are operating under an Administrative
Extension due to a permit renewal backlog within the Water Quality Control Division
Permits Unit. As of 2019, the Division has been actively working to synchronize renewal
of all three District WWTF discharge permits, with completion of the renewals expected
in 2020.
The WQCD classified the uses for Eagle River Segment 9a as Class 1 Cold Water Aquatic
Life, Recreation E, Domestic Water Supply, and Agriculture. This segment includes the
mainstem of the Eagle River from the confluence with Gore Creek to a point immediately
below the confluence of Squaw Creek. Water quality standards adopted for the segment
to protect the uses are ratified in Regulation No. 33 – Classifications and Numeric
Standards for the Upper Colorado River Basin and North Platte River. Improvements to
the AWWTF were designed to ensure facility compliance with all relevant water quality
and permitting regulations and requirements.
Circumstances unique to Segment 9a include the following:
Hybrid arsenic water + fish temporary modification. In 2013, the Commission
adopted a statewide arsenic (chronic) temporary modification to the water quality
standards for stream segments with dischargers, including Eagle River Segment
9a. The temporary modification, which has an expiration date of December 31,
2021, was established by the Commission to allow for a temporarily less stringent
application of the chronic arsenic standard in control requirements, such as CDPS
effluent limitations, while the Division works to resolve the underlying uncertainty
of the standard.
Site-specific temperature standards. In 2014, at the Upper Colorado River Basin
(Regulation No. 33) Rulemaking Hearing, the Commission adopted chronic site-
specific “transition zone” temperature standards for Eagle River Segment 8 (Gore
Creek from confluence of Black Gore Creek to the Eagle River), Segment 9a
(Eagle River from the confluence of Gore Creek to Squaw Creek), and Segment
9b (Eagle River from the confluence of Squaw Creek to Rube Creek). The Eagle
River site-specific standards were developed to address the natural warming that
occurs when streams transition from higher colder elevations to lower warmer
elevations. The site-specific standards were also developed to fully protect all
species “expected to occur” within the stream segments.

Aquatic Life Use impairment. Segment 9a between Berry Creek and Squaw Creek
is currently identified in Colorado’s Section 303(d) List of Impaired Waters and
Monitoring and Evaluation (M&E) List as provisionally (unidentified cause)
impaired for Aquatic Life Use – macroinvertebrates. However, the Division is
proposing to remove this portion of Segment 9a from the 303(d) list based on a
recent analysis that shows the reach is no longer impaired for Aquatic Life Use.
The Commission will consider the Division’s proposal during the 2019 Regulation
93 Rulemaking Hearing to be held in December 2019.
Clean, healthy streams are vitally important to the District, local governments, citizens,
and the recreation-based economy of the Eagle River basin and Avon in particular. The
District has taken an active role in a wide range of water quality matters within the Eagle
River watershed and has committed significant resources toward water quality monitoring
programs and source water protection. For several decades, the District, the Towns of
Avon and Vail, Eagle County, and other Eagle River communities and watershed
stakeholders, including the Division, have embraced a watershed-based approach to
water quality management. The stakeholders agree that effective management of water
resources requires an integrative, adaptive, and collaborative process.
To facilitate its role in this process, the District worked with the Division to implement a
watershed-based permitting approach for the Vail, Avon, and Edwards WWTFs. In 2010,
watershed-based discharge permits were developed for the first time for the Avon and
Edwards WWTFs. These permits included synchronized permit schedules and multi-
facility modeling to preserve the assimilative capacities of receiving waters. This approach
elevated protection of source waters and provided the District a powerful planning tool to
share and leverage resources in a more efficient, sustainable, and effective way than was
available through previously implemented standard practices.
Another important element of the District’s role in protecting water resources is its
development and implementation of a long-term strategy for handling and treatment of
wastewater at its three WWTFs. Compliance with increasingly stringent regulatory
requirements is becoming even more challenging, and the District continues to
investigate, leverage, and implement integrated WWTF system opportunities to achieve
regulatory compliance. By virtue of operating its three facilities as an integrated system,
the District can serve widely fluctuating populations, including up to 55,000 visitors and
residents to the Vail valley during peak tourist seasons.
Over the last decade, the District has spent considerable resources on studies and master
planning efforts to meet nutrient regulations, including development of a Capital
Improvement Plan with projects estimated at over $150 million. Nutrient regulations are
the underlying basis of a state and federal coordinated regulatory strategy designed to
reduce current and future nutrient pollution in Colorado’s surface waters. Nutrient
Regulations 85 and 31 were adopted by the Commission in March 2012 and require
WWTFs to meet effluent concentration limitations for phosphorus and nitrogen.
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 26
The purpose of Regulation 85 – a state-mandated nutrient control regulation – is to
provide a stepwise process for utilities to reduce nutrient discharges to state waters while
they assess additional needs and devise plans to meet future Regulation 31 nutrient water
quality standards. Regulation 85 requires wastewater dischargers with hydraulic
capacities equal to or greater than 2 million gallons per day to meet established numerical
effluent limitations for total phosphorus and total inorganic nitrogen and to monitor surface
waters for nutrients. The Division is revising stream nutrient water quality standards to be
considered for adoption by the Commission in 2027. With backing from the Division, the
District successfully developed a nutrient reduction plan and implementation strategy that
will maximize near and long-term watershed environmental benefits while preserving
fiscal goals and interconnected WWTF operations. Completing improvements to the Avon
WWTF is the first step in this process.
In addition to the future improvements planned for the Avon WWTF, the District completed
the following projects at the Avon and Edwards WWTFs since the 2010 permit renewals:
Chemically Enhanced Primary Clarifier (CEPC) treatment (2013) at the Avon
WWTF. This project effectively reduced BOD5 and total suspended solids (TSS)
loads to the facility’s aeration basins. As a result, the Division approved an
increase in the Avon WWTF’s organic loading capacity from 9400 to 11750 lbs.
BOD5 per day.
Nutrient treatment upgrades to the Avon and Edwards WWTFs. In 2013, the
District upgraded the Avon and Edwards WWTFs’ conventional activated sludge
secondary treatment process to the Modified Ludzack-Ettinger process to reduce
effluent TIN concentrations. The upgrades resulted in significant reductions of TIN
loading from the Avon and Edwards’ WWTFs. Note that the upgrades were a
voluntary and proactive effort by the District and not required for compliance with
the current WWTF discharge permits.
Consolidated treatment of wastewater solids from all three WWTFs at the Edwards
WWTF. Completed in 2016, benefits of this project include reduction of capital
expenditures and operation and maintenance life cycle costs for solids handling;
centralization of nutrient-rich recycle stream management and freeing up
treatment space at the Avon WWTF for future liquid stream improvements.
Decommissioning of Avon Autothermal Thermophilic Aerobic Digestion (ATAD). In
2016, the Avon WWTF decommissioned its ATAD system and began bypassing
primary and secondary solids to the Edwards WWTF via the collection system for
final digestion and processing.

(ii) Revenues and operating expenses for the proposed project and
alternatives.
Operating expenses for the Project will be funded from property taxes and monthly
service fees paid by commercial and residential customers throughout the ERWSD
service area, currently numbering 28,319 Single Family Equivalents (SFEs). The initial
operating expenditures of the project anticipate a nominal increase over current
conditions since no additional personnel are anticipated as part of this project. There will
be additional operating expenditures in the form of additional energy usage, which will be
offset by increased operating revenue due to the District’s rate increase strategy.
This project is designed to accommodate future growth throughout the service area,
mainly in the Town of Avon, EagleVail, the Town of Minturn, and peak season bypass
flows from the VWWTF. Future customer growth results in additional impact fees and
operating revenues, which will provide revenue to construct and operate the proposed
project, respectively. Operating expenditures at AWWTF have declined since the
decommissioning of solids handling in 2016.
Since the District’s wastewater service systems are integrated and comprised of
collection systems and several facilities between East Vail and Cordillera, wastewater
revenues are tracked as a whole and include the entire District service area. The District’s
total revised wastewater revenue for 2019 is projected at $20,589,000, with net operating
expenditures of $15,978,340 resulting in net funds generated from service revenue of
$4,610,660. A cashflow forecast with current and projected revenues and expenditures
is included as Attachment M.
In November 2019, the District’s Board of Directors approved a wastewater base rate
increase of 10%, from $5.19 per thousand gallons (Kgal) to $5.71 (Kgal). No base rate
increase is anticipated for 2021, but another 10% rate increase was modeled for 2022.
Regulatory demands, aging infrastructure at end of life, and historically high construction
cost escalations are affecting not only District customers, but water/wastewater utility
customers throughout the United States.
(iii)The amount of and security for any proposed debt and the
method and estimated cost of debt service.
The District generally funds its capital improvements through the issuance of debt, or
bonds. The project is partially funded by the money remaining from the existing Series
2016 General Obligation (GO) Bond issued in the amount of $23 million. Approximately
$11.7 million in bond proceeds remain that will fund the project. This debt is paid for with
a mill levy of .584 mills and was approved by District voters in May of 2014. Assessed
property values have climbed during this time period. The remainder of the project cost
will be paid by a 30-year Series 2020 Revenue Bond in the amount of $40 million. The
Board of Directors approved the budget containing the 2020 Revenue Bond at its
November 21 board meeting and the Board will approve the bond resolution the first
Attachment A

quarter 2020. A new debt service fee of $8.38 per SFE per month will be implemented in
January 2021. The remainder of the project costs will be paid from a portion of an
anticipated 30-year $30 million Series 2022 revenue bond with an estimated $6.14 per
SFE per month debt service fee to be implemented in January 2023. Figure 6 shows the
annual debt service payments for the District wastewater fund. This debt service payment
is divided by customers so as additional customers come online, individual debt service
rates stabilize or decrease.

(iv)Details of any contract or agreement for services in
connection with the proposed project.
There are no contracts or agreements for services in connection with the proposed
project beyond the existing District Service Plan, effective since 1995, and included as
Attachment N.
(v) A description of the persons or entities who will pay for or use
the project and/or service produced by the development and
those who will benefit from any and all revenues generated by
it.
Attachment A

Page 30
Residential and commercial sewer service consumers residing within the District service
areas will benefit, use, and pay for the proposed project. All ratepayers will benefit due to
the increased nutrient removal and associated anticipated source water improvements in
the entire watershed.
(vi) Documentation of financial and technical capabilities of the
applicant/ owner, to demonstrate that the project will be
completed in a reasonable length of time and will comply with
all applicable Town requirements.
The District has the financial and technical capabilities to implement the project in a
reasonable length of time and in compliance with all applicable Town requirements. The
delivery method selected for the project engages a general contractor early in the project,
and Moltz Construction has been providing valuable schedule input and constructability
analysis throughout the design phase.
The project has several constraints due to constructing a major expansion/rehabilitation
within an operating wastewater treatment facility. First, the plant must maintain regulatory
compliance at all times, including during construction. During the summer and winter
seasons, all of the plant’s processes must be online to treat wastewater and meet
discharge permit requirements. Second, the existing aeration basins are to be modified
and expanded. The basins were not designed to be full of water without earth pressure
supporting the concrete walls, so basins must be dewatered while new basin volume is
excavated and constructed to the east. In addition, the existing aeration basin volume is
buried, with dangerous confined space access and a lawn over the concrete double tee
roof. A major component of the project is to add a superstructure to the buried basins, as
the existing roof is compromised and in need of replacement. This will also improve
operator safety and improve access to equipment and instrumentation in the basins
critical to process control and permit compliance.
The existing structure requires the roof to stabilize the walls; therefore, stabilization efforts
must be executed, including removal of one existing double tee section, installation of
temporary bracing, and concrete installation (form, pour, cure). This process will be
extremely time-consuming. In general, the critical path schedule of 32 months is dictated
by construction of new basins and modifications to the existing aeration basins.
c) A report completed by a qualified environmental engineer summarizing
the environmental impacts of the project on air quality, threatened or
endangered species, visual quality, noise and vibrations and odors,
within the area to be impacted by the project.
Please see the Environmental Impact Report, included as Attachment F, summarizing the
environmental impacts on air quality, threatened or endangered species, visual quality,
noise, vibration and odors. Environmental impacts of the project are minimal and the
District is pursuing mitigation of those impacts.
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 31
Air quality in the area will improve due to the installation of new HVAC and odor control
systems as part of the project. The odor control strategy for the project will result in the
virtual elimination of off-site odor excursions. Odor excursions were mostly eliminated
with the decommissioning of solids handling at the AWWTF in 2016. The previous solids
digestion process was notorious for creating fugitive odors. The new project will focus on
remaining odors, and the odor control strategy will be split into two processes: primary
and preliminary treatment process odors will be scrubbed using granular activated carbon
(GAC) systems, and aeration basin odors, typically untreated, will be collected and
discharged through high plume high velocity fans, which mimic a large stack height and
discharge the air higher into the atmosphere.
Vibration and noise were also studied as part of this application process, especially due
to the additional HVAC and high velocity fans. A separate noise expert was retained for
the analysis, which demonstrated that noise and vibration generated by the project will
not impact or degrade ambient levels. The background ambient noises for adjacent
properties are Interstate 70 and Highway 6. Noise mitigation is described in more detail
in Section II h) 2) below.
The visual appearance of the facility will slightly change, but the District is committed to
mitigating its visual impacts and in many cases improving visual quality. The architecture
of the new buildings will closely match the existing architecture and color palette of the
inherently industrial property. In addition, buildings not affected by the proposed project
will be painted to achieve a more cohesive appearance.
Along the western fence line, landscaping and architectural fencing will be utilized to
buffer the site from the Liftview Condominiums property. The current fence line is not
located on the property line; but rather to the east. As part of this project; the fence line
will be relocated to the property line. Liftview was engaged in the project since its inception
and is involved in the selection of the fencing material. The nature of the work, including
removal and replacement of precast concrete roofs and installation of precast concrete
wall panels, will require the erection of a tower crane which will be quite visible in the
area. The crane is expected to be on site for approximately 24 months.
Normal temporary impacts can be expected during the duration of the construction project
with efforts to continually mitigate. Odors and air quality will be maintained by monitoring
and mitigation of fugitive dust during construction. Odor control system interruptions will
be minimized with tightly coordinated tie-in and startup specifications. In addition, the
District is intending to utilize temporary noise reduction fencing along the western property
line.
d) A report completed by a qualified traffic engineer summarizing the
impact of the proposed project on the Town's existing and planned
transportation network.
During the Feb. 27, 2019, preapplication meeting, Town of Avon staff waived the
requirement for a formal traffic study report. Upon project completion, there will be no
permanent traffic impacts generated by activities at the AWWTF. No additional staff will
Attachment A
Avon WWTF 1041 Permit Application

Page 32
be added to the project. Truck traffic hauling biosolids from the AWWTF was previously
eliminated with the decommissioning of solids digestion at the AWWTF in 2016.
During the construction phase, there will be a traffic increase in to support construction
activities. This will be mitigated by District trucks and equipment being staged in western
Edwards for the duration of the project. In addition, the impacts to District staff at the
facility will be mitigated by avoiding scheduling large meetings at the AWWTF conference
room, promoting flexible work locations, and other internal measures to reduce vehicle
trips to and from the facility.
The general contractor will schedule deliveries and tightly coordinate activities and
parking to minimize impacts to the Town’s transportation network and confine disruptions
to within the AWWTF fence line. The precast roof requires hauling of very large precast
concrete sections; the contractor has already planned the haul route to avoid the school
area. The District is aware of the heavy pedestrian use associated with nearby residences
and Avon Elementary school and will schedule deliveries to avoid peak times.
e) A description of the existing levels, demand for, adequacy and the
operational and maintenance costs of public services and facilities
affected by the project, including services and facilities of the Town and
other affected local governments, including but not limited to Eagle
County, school districts and special districts.
The Avon WWTF Nutrient Upgrades Project will not place any additional demands on
local government services.
f) A report summarizing the socio-economic impacts of the proposed
project.
There are no socioeconomic impacts, beyond rate increases, of the proposed project as
it is an expansion of an existing wastewater treatment facility. The requirement to submit
a report was waived by Town of Avon staff during pre-application communications. The
rate increases proposed by the project apply to all customers, and the District’s rates are
quite competitive when compared to similar jurisdictions. The rates are based on number
of SFEs and metered usage, so larger homes and commercial users pay higher water
and sewer bills. Figure 7 demonstrates ERWSD (Vail) and UERWA (Eagle Vail to
Cordillera) water and sewer rates compared to other similar communities before the
proposed rate increases take effect.

g) A report summarizing the anticipated impact of the project on existing
land uses within the Town and other existing property rights.
i) A description of all property rights, including water rights, surface rights,
mineral rights, rights-of-way and easements, which must be obtained or
will be affected, in order to construct and operate the projects; the
identity of the owners of these rights; and the anticipated methods of
acquiring these rights.
There are no property rights, including water rights, surface rights, mineral rights, or rights
of way or easements that need to be obtained or will be affected by constructing and
operating the project. The District is the fee simple owner of Tract N and Tract O,
Benchmark at Beaver Creek Filing 2, which is zoned for Public/Civic use. The proposed
construction and operation of the project lies within the boundary of the site and within
existing setbacks.
At the conclusion of the project, the District will likely abandon a 25-foot wide Holy Cross
Energy electric easement, as it provided power service to the barn, and that service has
been abandoned.
ii) An assessment of whether the proposed project is consistent with the
Town's land use policies as set forth in the Comprehensive Plan and this
Development Code.

improve efficiency, reduce energy consumption, reduce emission of pollutants,
reduce consumption of non-renewable natural resources and attain
sustainability;
The project directly reduces emission of pollutants in the gas streams and reduces the
concentrations of nutrients in the wastewater effluent, created by human impacts such as
urine, fecal matter, and detergents. Sustainability is woven throughout the project design,
including larger pipe diameters which require less pump motor horsepower, selection and
utilization of the highest efficiency aeration blowers, and the use heat recovery on the
HVAC system to increase inlet air temperatures and reduce the consumption of natural
gas for heating. Further, the proposed improvements to preliminary treatment result in
better screenings and grit and consequently fewer vehicle trips to the landfill.

The project does not impact and does not affect existing and proposed land uses. The
project is an expansion of an existing WWTF and must be constructed on the subject
property. No changes in land use on the subject property or adjacent properties are
proposed as part of this project.
h) A report summarizing all mitigation that is proposed to avoid, minimize,
rectify, compensate for or eliminate adverse impacts and to maximize
positive impacts resulting from the proposed project for each impact
category to be affected by the proposed project.
(1) A description of the impacts and net effects resulting from the
proposed project, which are irreversible and irretrievable.
The project’s irreversible and irretrievable impacts generally are limited to the construction
of additional wastewater treatment tank volume and expansion of the built form of the site
with a retrofit of the existing aeration basin volume with a superstructure building and
construction of superstructures on new tankage.
The building heights on the site will not increase and the elevation of the new structures
will match existing building elevations and rooflines on the adjacent structures. Rooftop
HVAC and odor control equipment will project above the rooflines as shown in the design
drawings.
There will be a small net increase in impervious area on the site, which will be mitigated
by improved stormwater collection and treatment systems. Finally, the buildings on the
site will be painted to match and to reduce the visual massing appearance and create the
appearance of a more cohesive campus.

(2) A description of the methodology, including mathematical equations,
to be used to project and measure the effectiveness of mitigation
measures proposed over both the short and long term.
In addition to site coverage of new buildings and paving, the following measures are
identified as requiring mitigation during construction and during facility operation:
Fugitive odors from wastewater treatment processes
Fugitive noise from HVAC and odor control equipment
Visual appearance of the facility
Temporary impacts during construction of the facility
Odor Control
Odor associated with the AWWTF has been a long-standing concern of both the District
and the Town of Avon. In 1995, a solids-handling treatment technology known as first-
generation autothermal thermophilic aerobic digestion (ATAD), was constructed. During
the initial years of operating this new technology, strong odors were produced causing
distress for the Town of Avon as well as District management and operations staff. Since
that time, the District implemented measures to reduce odors from all treatment facilities.
During the 2012 Wastewater Treatment Facilities Master Plan, it was determined the best
operational scheme for the District was to consolidate all solids handling at the Edwards
WWTF. In 2016 all solids were treated at the EWWTF, and in 2017 all solids handling
equipment was decommissioned and removed from the AWWTF site. These
improvements drastically decreased odors generated from treatment processes. No
official odor complaints were linked to AWWTF operations since the decommissioning of
solids handling in 2016. Some odor complaints were investigated and linked to the odor
produced during the natural turnover of Nottingham Lake.
As part of the Nutrient Upgrades Project, the odor control system will be completely
upgraded. Webster Environmental was hired to test and model odor emitted from the
AWWTF and recommend treatment strategies. The goal for the new odor control system
was to replace a less efficient and aging odor control system with a new system that will
further reduce odors and increase redundancy. An Odor Control Summary Report is
included as Attachment P.
Odor is often measured in dilutions to threshold (D/T). D/T values are determined by an
odor panel consisting of trained personnel who are scientifically screened to determine
their smelling acuity to butanol. D/T refers to the number of dilutions of an odorous air
sample are required before half the panel members are still able to detect the presence
of the odor under controlled “clean” conditions. A high D/T indicates a strong odor
requiring many dilutions to render it undetectable.
The model output predicts the highest D/T level, estimated throughout the area of
analysis. The resulting peak D/T levels are shown graphically on odor contour plots.
Essentially, the model predicts the number of dilutions in the atmosphere in the downwind
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 42
D/T, or the detection threshold of the odor. In this study, the peak hourly average D/T
levels and the peak one-minute D/T’s were used to predict receptor D/T odors by applying
a multiplier to account for short exposure to odors. The peak D/T is relevant for odors,
since the odor plume meanders and is very transient. Odor complaints are generally
related to peak odor levels, as opposed to an hourly average odor level. This is a
conservative approach to odor modeling.
An odor detection threshold of seven (7) D/T was selected for several reasons. An odor
with a detection threshold of seven dilutions or less may not be detected because it could
be overwhelmed by other natural odors in the area such as grass, trees, soil and flowers,
or it may not be detectable at all. Seven D/T is considered background odor levels.
Webster modeled the odors emitted from the facility while ATAD was still operational and
under current conditions (Figures 11 and 12, respectively). The modeling shows D/T over
a 5-minute period.

Figure 12: Current Conditions– Peak 5 Min Average D/T Contours
From the results of the odor investigations, Webster analyzed multiple different odor
treatment technologies and recommended the proposed strategy at AWWTF. Odor
streams from the facility were separated into two different areas:
Headworks, primary and preliminary treatment (strong odors)
Aeration basins (weak odors, typically not treated)
Because the processes produce two different types and strengths of odors, two different
treatment technologies were selected for this project.
Headworks, primary and preliminary treatment:
Carbon adsorption was selected as the best treatment technology for odors from the
headworks, primary and preliminary treatment processes. Two complete systems, each
with two different types of activated carbon, will be installed on the south side of the
AWWTF site and use an existing duct to pull odors from the processes on the north side
of the facility. Each system will be able to treat 100% of the air flow, providing complete
redundancy of this odor control process. The carbon scrubber system (similar to Figure
13) includes a fan that pulls the foul air from the process areas and pushes it through a
fiberglass vessel containing two different types of activated carbon specially selected for
the odorous compounds found in wastewater.
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 44
Activated carbon has a complex pore structure with a very large surface area. Odorous
compounds are transferred from the air being treated to the surface of the carbon as the
air is moves through the carbon bed. There is a physical attraction between the compound
and the carbon once contact is made which causes a bonding. The compounds will
continue to adsorb onto the surface of the carbon until all the pore space in the carbon is
used up. When that happens, odors will breakthrough and the carbon must be replaced
or regenerated.
Figure 13: Typical carbon scrubber system
Aeration Basins:
In most of Colorado, aeration basins are not covered by a building, but rather are open to
the atmosphere. As such, typically aeration basin odors are not treated. In areas where
wastewater treatment facilities are close to city centers and in other resort destinations,
aeration basins are often covered like those at AWWTF. To treat the weaker odors from
the aeration basins, Webster and Carollo recommended using high velocity Strobic Fans.
The high velocity fans send air up high above the facility and use dispersion and dilution
to treat odors. This model selected for the AWWTF has an effective stack height of 55 ft
(it will send air to the same elevation as a physical stack of the same height). Figure 14
illustrates a similar model to the Strobic Fan designed for this project.
Figure 14: Strobic Fan
Attachment A

Page 45
The proposed odor control system was modeled to verify that future odors are minimized,
and the results are illustrated in Figure 15. The highest concentration of odor in the future
model shows 9 D/T, which is very close to the lowest perceptible concertation of 7 D/T.
This odor condition will only occur during rare atmospheric conditions and is expected to
occur less than 12 times per year for 5-minute periods.
Figure 15: Conditions After Project Completion– Peak 5 Min Average D/T Contours
Noise Modeling
During the development of the odor control strategy, noise generation from the selected
equipment was raised as a potential concern by the project team. To ensure the District
meets the goal of minimizing impacts to neighboring properties, THD Productions was
hired to model the noise profiles from the new equipment proposed for the AWWTF
Nutrient Upgrades project. A full noise analysis report is included as Attachment Q.
Noise is measured in decibels (dB). Normally, 0 dB on the decibel scale is set to the
quietest sound a healthy child can hear (Figure 16). Ten times more powerful than 0 dB
is 10 dB. Ten times more powerful than 10 dB is 20dB, or 100 times more powerful than
0dB. 30 dB is 1,000times more powerful than 0 dB.
Attachment A

Page 46
Figure 16: Reference decibel scale
The baseline for acceptable sound levels was determined to be below the ambient noise
at the nearest receivers (residents in Liftview and River Edge Apartments). THD
Productions modeled the existing ambient noise in the vicinity of the AWWTF. Then, the
new odor control equipment, including the high velocity fans and carbon system fans,
were modeled. Ambient background conditions during the day and at night can be seen
in Figures 17 and 18, respectively. The ambient noise is slightly quieter during the night.

THD worked closely with Carollo Engineers and ERWSD to model and help select
equipment that met the odor control requirements that would not cause noticeable sound
to nearby residents and users of Nottingham Park or the recreation path. After careful
selection, the noise data for the high velocity fans (odor control for the aeration basins)
and the carbon scrubber fans (odor control for the headworks and primary treatment)
were modeled.
The high velocity fans on top of the aeration basins were selected specifically because
their noise profile is below the ambient noise of Highway 6 and I-70. Figure 19 shows the
noise pattern of the proposed Strobic high-plume exhaust fan assembly radiating from
the roof of the new aeration building to the north of the AWWTF facility. The valley floor
is between 8 and 20 dB, with the AWWTF buildings shadowing the noise radiation to the
west, south and east. The closest noise receivers are the residents at Liftview
Condominiums, specifically buildings D and E. The sound output of the aeration fans is
below (quieter than) the ambient traffic noise levels.
Figure 19: High Velocity Fan Noise Profile
We now see an almost silent Avon valley floor, as shown in dark gray with only a slight
radiation of sound from the centrifugal fans inside their enclosures at that south side of
the odor control building. This is an excellent example of how modeling can help us see
the effects of changes in overall sound output – well below even the measurable limit of
ambient noise in the environment. All calculated levels in Figure 20 are well below the
quietest modeled ambient noise values for I-70 and Highway 6. Therefore, the centrifugal
Attachment A

fans with enclosures were specified for this project as they will not significantly degrade
the existing noise levels in the impact area.

Visual Impacts
Visual impacts are of great concern to the District. The District worked with Eidos
Architects to repaint each facility to create a cohesive campus that will be a source
of pride for the District and the Town of Avon. Buildings not already powder-coated
will be painted complementary Sherwin Williams Colors including Chatura Gray
(SW 9169), Garret Gray (SW 6705) and the trim will be Chateau Brown (SW 7510).

Temporary Impacts during Construction
During construction, Moltz will be subject to multiple contractual requirements and
permits related to mitigation of impacts to the public. For example, Moltz will be
required to obtain a CDPHE construction stormwater permit and a dewatering
permit. A stormwater management plan will be submitted by the contractor, and
the Owner and Engineer will monitor and assess the effectiveness of the Best
Management Practices (BMPs) continually throughout the project and require
changes if conditions warrant. Both permits require periodic sampling to ensure
that no sediment leaves the site towards the Eagle River. Further, the AWWTF has
an existing stormwater discharge permit, which requires quarterly sampling,
monitoring, and reporting to the CDPHE. Another potential impact to the public will
be dust. Fugitive dust will be managed by dust suppression activities including the
application of water and/or magnesium chloride. Disturbed stockpiles and areas
will be seeded and hydromulched, and BMPs will remain in place until final
vegetative cover is established.
Deliveries will be tightly coordinated to reduce temporary traffic impacts. In
addition, all work will occur during the days and times explicitly allowed by Avon
Municipal Code. If night work is required, it will be confined to the interior of the
WWTF and will not produce any off-site noises.
There will be a temporary visual impact in form of a large tower crane erected at
the facility. The crane is necessary in order to hoist concrete double-tee roof
members and install new ones, along with precast wall panels. Many large projects
in Vail and Avon have had cranes in recent years and this will be a similar piece of
Attachment A

Page 53
equipment. It is anticipated that the crane will be on site for approximately 24
months.
(3) A description and location of any monitoring devices to be used
to measure impacts of the project and effectiveness of
mitigation measures.
The impacts of the project in terms of the additional reduction in nutrient loading to
the Eagle River will be continually measured and reported to the CDPHE as part
of the Discharge Permit reporting requirements. The new AWWTF discharge
permit will have strict limits and the AWWTF is required to comply with all
constituent limits as outlined in the permit. We expect a considerable reduction in
nitrogen and phosphorous discharge to the Eagle River which will benefit in-stream
water quality and biological health.
Odor levels will be monitored on a periodic basis via sampling to determine the
exact lifespan of the GAC media. Media replacement is anticipated approximately
every seven years. The District collects samples and sends them to a laboratory
to measure Reduced Sulfur Compounds (RSCs) typical of wastewater odors as
well as measuring intensity of odors, or D/T.
(4) A description of how and when the proposed mitigation
measures will be implemented and financed.
The proposed mitigation measures are included in the project scope and will be
implemented by the project team during construction, or by the District operations
team after construction. The financing for the mitigation during construction will be
financed with the debt service for the overall project funding as defined in more
detail in Section II b) 8) ii and iii of this application. Mitigation during the operational
phase of the project (after construction) will be financed from customer rates as
approved by the ERWSD Board of Directors on an annual basis and will be
absorbed in annual operating budgets in perpetuity.

SECTION III: Avon Development Code 7.40.640 Submission
Requirements applicable to the Avon WWTF 1041
In addition to the 1041 Application Submittal requirements under AMC 7.40.220,
additional submittal requirements are applicable to Special Water or Wastewater
Projects (SWWP). The expansion of the Avon WWTF falls under these additional
requirements.
a) The need for the proposed construction, expansion or
modification of the SWWP;
The Avon wastewater facility was originally constructed in 1966 and underwent
numerous improvements over the years, most recently a major liquid-stream
capital improvement in 2013. The existing facility has a permitted hydraulic
capacity of 4.3 million gallons per day (MGD), and the operation is fully compliant
with current regulatory requirements for the removal of BOD5, total suspended
solids (TSS), ammonia (NH4) and disinfection.
The proposed project will increase the organic treatment capacity of the facility to
meet nutrient removal requirements and to address condition assessment
projects, including:
• Preliminary treatment
• Primary treatment
• Primary effluent flow equalization
• Secondary treatment:
- Aeration basin modifications to operate in the anaerobic/anoxic/oxic
(A2O) process configuration for biological nitrogen and phosphorus
removal. Includes aeration basin expansion
- Construction of a third secondary clarifier
• Chemical feed and storage
• Improvements to odor controls, including upgraded high velocity/plume fans and
improved odor controls
The AWWTF conveys solids to EWWTF through a collection system for digestion
and dewatering. The AWWTF accepts influent bypass (intermittent) and waste
activated sludge (WAS, constant) from the VWWTF via the collection system,
which is predominately treated in Avon’s primary sedimentation basins (Carollo,
2017).
This project will allow the Avon facility to accept increased bypass flows from Vail
during seasonal tourism peaks, which leverages the interconnected nature of the
three wastewater treatment facilities. This reduces both the capital costs of a more
difficult and higher cost facility expansion and the risk of a permit violation at the
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 55
VWWTF. Improvements at AWWTF leverage the available area for expansion,
benefit the Eagle River watershed with enhanced treatment controls and give
operations staff additional capacity and flexibility to operate the regional system in
compliance with State nutrient limits. Since the AWWTF is the largest hydraulic
capacity WWTF in the system, the improvements will have the greatest
environmental benefit to the receiving waters of the Eagle River. Planned
improvements are designed to treat flow projections and meet regulatory
compliance goals at the Avon facility through 2037.
b) The planned level of service in relationship to projected user
demand, both regionally and within the Town;
The level of service will increase in the form of improved effluent water quality for
the current and future population. The District developed and maintained growth
projections to properly plan for anticipated levels of service for the region. The
2017 Master Plan Update (MPU) considered a combination of population
projection and growth scenarios to facilitate process capacity analyses and future
permit limits for each of the three WWTFs (Vail, Avon and Edwards).
Figure 25. District current and projected SingleFamily Equivalents (SFE) by subdivision
(from 2017 MPU).
Flow and loading projections were developed for several scenarios, including 10-
day winter peak flows and 10-day spring peak flows and loads associated with
elevated Inflow & Infiltration (I&I) contributions in the collection system (Carollo,
2017). ERWSD and other seasonal resort communities are somewhat unique in
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 56
the wastewater industry in that its seasonal peaks vary dramatically from peak
times to shoulder seasons.
The AWWTF is part of a connected system that includes Edwards and Vail
facilities. This connectivity creates unique opportunities for system-wide operation
allowing upstream plants to pass flow and/or solids downstream when conditions
are advantageous to do so. This best leverages capital expenditures among the
three facilities.
The average daily flow through the entire District wastewater system (split between
the three facilities) is approximately 5.5 MGD, with the maximum peak week flow
of 7.7 MGD and a minimum flow of 3.7 MGD. Historical average single-family
equivalent (SFE) growth since 1997 in District boundaries ranges from 1.14 % to
2.12% annually. Those growth projections were utilized for annual increases in the
Vail and Avon/Edwards systems, respectively. At the projected influent flows and
loads, the capacity of the Vail WWTF will be limited by aeration basin and treatment
performance (Carollo, 2017). The need for flow diversions to AWWTF reduces the
capital costs of a near-term expansion in Vail and lowers risks of a permit violation
at Vail in addition to handling the expected residential and commercial growth in
Avon in the same planning horizon. Water discharged to the Eagle River will be
improved as a result of this upgrade.
The planned expansion creates an appropriate level of service in relationship to
projected demands of Avon and the region. Avon, including the largely unbuilt
Village at Avon PUD, represents the largest increase in anticipated SFEs over the
planning horizon.
c) The approximate number of residential, commercial or industrial
users of the proposed SWWP in terms of existing Town residents
and non-Town residents;
The 2017 MPU detailed actual and projected Single Family Equivalents (SFEs)
based on available data. In 2014, Avon and the Village at Avon represented a
combined 4,039 SFEs out of a total of 25,967 SFEs served by the District.
By 2030, Avon’s SFE contribution to the District was projected to grow to 7,033
SFEs – a potential 57% increase in service demands, shown in Figure 25.
Currently, the District serves a total of 28,319 SFEs, and growth projections are
1.14% and 2.2% annually in the Vail and Avon/Edwards service areas,
respectively. This indicates a 1.7% annual growth rate from the 2014 data to 2019
(present day). Avon contains the largest amount of undeveloped land and future
water/wastewater customers within the ERWSD service area.

d) Locations of and engineering drawings for wells, diversion
structures, reservoirs, storage structures or other structures or
facilities required for the SWWP;
All proposed improvements will be within the AWWTF site, no satellite structures
will be impacted. Below-grade tanks for wastewater process treatment will be
constructed immediately west of the existing tankage. Locations of existing and
proposed improvements at the AWWTF are included in Attachment C. There are
no proposed wells, diversion structures, or reservoirs as part of the proposed
project.
e) A description of the proposed capacity of the SWWP, treatment
methods and technologies, proposed budget and service area of
the SWWP;
The proposed hydraulic capacity of the plant remains as permitted currently at 4.3
MGD, and treatment methods and technologies were detailed in Section II b) 1)
and Attachment I of this application. The biological treatment capacity of the plant
will be increased from 11,750 lb/day to 13,100 lb/day BOD5.
The project opinion of probable cost and budget has been included in Attachment
L. Project funding will be provided from a variety of sources, including:
- Accumulated Wastewater Tap Fes that make up a part of the District’s
current general fund balance of $47.2 million (as of June 30, 2019).
- Proceeds of Series 2020 Wastewater Revenue Bonds in the amount of
$40 million that result in additional debt service rate of $8.38 per SFE
effective January 1, 2021.
If additional Wastewater Tap Fee revenues are generated, the amount of the
Series 2020 and Series 2022 Revenue Bonds could be reduced. There is currently
no Capital Replacement Program fee in place for the Wastewater District. The
revenue comprising the operational budget of the AWWTF comes from monthly
user service rates.
f) A map of the service area of the SWWP;
A Service Area Boundary Map for the AWWTF is included as Figure 26, and a map
of the entire ERWSD service area is included as Attachment J. The District service
area includes much of the upper Eagle Valley from East Vail to Cordillera. The
service area of the AWWTF generally includes a portion of Vail, the entirety of
Minturn, Beaver Creek, EagleVail, and Avon (excluding Mountain Star and
Wildridge). Since the AWWTF receives waste activated sludge (WAS) from the
Attachment A

December 6, 2019
Page 58
VWWTF and bypass flows from the VWWTF, the VWWTF is considered a part of
the service area based on certain operational configurations
Figure 26: Map of the Avon WWTF service area
g) A list of end users and types of land use development to be served
by the proposed SWWP;
The District provides a total system treatment capacity of 9.95 MGD through three
integrated wastewater facilities located in Vail, Avon and Edwards. The
improvements proposed benefit all end users and land use types within the District
boundaries, from East Vail to Cordillera.
It is important to note that land use decisions are approved by other entities outside
of the District, namely the towns of Vail, Avon, Minturn and Eagle County. The
proposed project is designed to treat all current and future commercial, industrial,
and residential users of the wastewater system.
h) A description of proposed methods of ensuring efficient use of
water resources, metering of all uses, examination of rate
structures to discourage waste and recycling of water for reuse
where permissible under Colorado water law;
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 59
The District’s tiered rate structure already encourages water conservation by
penalizing excessive use and charging higher rates for higher usages. As part of
the proposed revisions to rates, the tiers are changing to further encourage
conservation. Second, the District is in the process of implementing a water
budgeting system and reviewing landscaping plans for new developments as they
are referred by local land use authorities. The District has a dedicated Water
Demand Management coordinator position whose sole responsibility is to
collaborate with land use authorities, developers, and landscaping contractors to
promote responsible landscaping and water usage. The District implemented
Advanced Metering Infrastructure, which engages the customers directly with their
water meters to track excessive usage and monitor irrigation demands. Summer
irrigation is the highest demand on the system and indoor usage, treated by the
wastewater facilities, is largely unaffected by these conservation efforts.
During construction, the proposed Project will utilize non-potable water (internal
process water that is not treated to meet drinking water standards) where possible,
such as leak-testing new basins and for construction water such as dust
suppression and soil compaction. Landscaping will be designed to minimize
irrigation needs.
i) A study or report evidencing that the proposed SWWP will supply
water of a quality which meets current standards of the Colorado
Department of Public Health and Environment;
The proposed Project will increase the organic treatment capacity of the facility
and includes modifications to process areas to meet nutrient removal requirements
and to address condition assessment projects recommended in the 2017 MPU.
The project will supply effluent discharge that meets or exceeds current standards
of the Colorado Department of Public Health and Environment as outlined in
Attachment E. Results of plant process modeling are included in Attachment I.
j) Any documents describing the engineering, architecture or design
of any impoundment structures associated with the SWWP,
whether surface or subsurface, and any appurtenant facilities,
including any submittals by the applicant to the office of the State
Engineer;
All documents and specifications for engineering, architecture and landscape
design of the Project are provided in and Attachment C. There are no dams,
diversions, or impoundments associated with the project and therefore no
submittals to the State Engineers office are required.

k) If applicable, the applicant will attach a copy of the completed or
proposed site application form required by the Colorado Water
Quality Control Commission;
CDPHE permits and site application forms in are included in Attachment E. Site
Application approval was received on July 1, 2019, and Process Design Report
approval is anticipated in December 2019.
l) Any health and safety hazards, including exposure to hazardous
materials, which may result from the siting of the proposed
construction, expansion or modification of the SWWP;
There will be no exposure to hazardous material related to the proposed project.
During construction of the proposed Project, a variety of heavy equipment vehicles
will access the site. These vehicles will have standard capacities for fuel, motor oil,
and hydraulic fluids; vehicle refueling will likely take place on-site. Vehicles will be
properly maintained to avoid accidental release or exposure. All applicable
Occupational Safety and Health Administration (OSHA) health and safety
standards will be followed by on-site crews to prevent accidental release and
exposure of chemicals from construction equipment.
After construction, one new chemical, Micro-C will be used at the AWWTF. Micro-
C is comprised mostly of glycerin and water, is not classified as a hazardous
chemical and is not regulated for transportation by the US Department of
Transportation. The most hazardous chemical currently utilized on the site is a
10% solution of Sodium Hypochlorite and its usage will be discontinued as part of
this project. A copy of spill prevention, control and countermeasures plan is
included in Attachment O and a list of chemicals stored on site is included as Table
1. Construction of chemical storage facilities will be compliant with prevailing
building and fire safety codes.
m) How the proposed construction, expansion or modification of the
SWWP and its impacts will conform to the Comprehensive Plan
goals, objectives and policies;
As described in Section II g) ii), Improvements at the facility generally conform to
the Town of Avon Comprehensive Plan (2017), including the following goals and
policies:
Policy I.1.2: Develop community services and facilities based on demand.
The design and capacity of the facility is based on current and future demands
from development in Avon and the remainder of the AWWTF service area. The
Attachment A

Page 61
project is projected to meet all regulatory and capacity considerations immediately
upon completion and for the next 20 years.
Goal J.1: Collaborate with other agencies to implement this plan and to ensure
Avon’s needs and goals are being met.
ERWSD continually collaborates with other agencies on important regional water,
environmental, and sustainability efforts. Such agencies include but are not limited
to:
Town of Avon
Eagle County
Town of Vail
Northwest Colorado Council of Governments (NWCCOG)
Vail Resorts
Colorado Department of Public Health and Environment
U.S. EPA
Holy Cross Energy
In addition, the District’s General Manager Linn Brooks is the Chair of the Colorado
Water Congress and supports Eagle River Watershed Council’s education and
outreach, functions and sampling and analysis efforts.
Policy J.1.1: Collaborate with county, regional, state and federal agencies and
adjacent municipalities on cooperative planning efforts and regional
issues.
The District collaborates with county, regional, state, and federal agencies on
water quality, transportation, economic, and housing issues. We are project
partners with the Colorado Department of Transportation (CDOT), installing and
rehabilitating water and wastewater utilities in conjunction with transportation
projects. We collaborate with the towns of Vail and Avon and Eagle County on
planning and development issues and are working with many member
metropolitan districts to roll out water conservation and water budgeting policies.
Finally, District representatives will be presenting the proposed rate increases to
many of our constituents in the upcoming months.
Policy G.1.2: Maintain the Eagle River as a valued resource in accordance with
the most recent Eagle River Watershed Plan.
The project is in direct conformance with the Eagle River Watershed Plan and the
District frequently collaborates with the Eagle River Watershed Council and
supports its education and outreach, functions and sampling and analysis efforts.
Conformance with the Watershed Plan is described in further detail below.

n) How the proposed construction, expansion or modification of the
SWWP and its impacts will conform to any applicable regional and
state plans, goals, objectives and policies;
Proposed modifications to the AWWTF comply with regional planning goals and
objectives. This includes goals of the 2012 NWCCOG 208 Plan, our regional water
quality management plan in compliance with Section 208 of the Clean Water Act.
Specifically, the following NWCCOG Policy goals support the Avon Project:
Policy 1: Protect and Enhance Water Quality. Meet Existing Water Quality
Standards; Implement Water Quality Improvement Projects.
Proposed modifications to the AWWTF are necessary to meet future permit limits
for nutrients under Regulation 85. This project will increase wastewater treatment
and improve water quality in the Eagle River watershed.
Policy 4. Decisions to locate water supplies, wastewater treatment systems, and
other water and wastewater facilities shall be made in a manner than protects
water quality and the aquatic environment. Where growth and development
requires the need for additional facility capacity, existing facilities should be
expanded instead of developing new facilities, unless expansion is not feasible
because of technical, legal or political reasons.
The Project is an expansion instead of a new facility and can accommodate current
and future populations of the service area.
Policy 5.3 Storage Handling and Use of Hazardous Substances.
The Project is compliant with best practices for the storage, handling, and use of
hazardous substances. Additional information included in Section II b) 5) of this
application.
Policy 6.3 Sanitation Districts. Sanitation Districts, water and sanitation districts
and wastewater management authorities are designated as management
agencies for the construction, operation and maintenance of wastewater facilities
within their service area.
The project is prepared and submitted by the appropriate management authority,
the Eagle River Water & Sanitation District. The Project will also comply with
applicable State water quality requirements as described herein.
The project is also supported by water quality objectives of the 2013 Eagle River
Watershed Plan, including:
Objective 3.1. Reduce or eliminate impacts to water quality in aquifers, rivers,
streams and lakes from existing land use and future growth.
The primary objective of the proposed project is to improve water quality in the
Eagle River. The main source of nitrogen and phosphorous to the wastewater
Attachment A
Avon WWTF 1041 Permit Application
December 6, 2019
Page 63
treatment facilities originate from human waste (urine and feces), soaps, and
detergents. Treating and reducing these concentrations through the wastewater
treatment processes, and ultimately reducing the nutrient concentrations in the
effluent is intended to benefit water quality and biological health in the Eagle River.
In addition, the District is unique in that its WWTFs currently require compliance
with stormwater discharge permits. The project scope includes improved
stormwater treatment infrastructure, which mitigate the impact of development on
the property.
Strategy 17. Support service plan amendments and/or wastewater treatment plant
improvements designed to maintain or enhance water quality in local streams and
rivers.
This objective is met since the project is a wastewater treatment plant improvement
designed to enhance water quality in the Eagle River.
o) The increased demand that the SWWP will place on the following
public services, both regionally and within the Town: employment,
schools, commercial services, health services, police and fire
protection, solid waste disposal, storm water collection and
release systems, power, communications, other public and quasi-
public utilities and other planned public services;
Improvements to the AWWTF will not place undue burdens or unreasonably
increase demands for public services. The District is a public service provider
responsible for operation and maintenance of three wastewater treatment facilities
serving the Gore and Eagle river valleys:
Vail – 2.7 MGD capacity
Avon – 4.3 MGD capacity
Edwards – 2.95 MGD capacity
These facilities operate through a collection system of approximately 207 miles of
collection lines, with an average daily flow of approximately 5.5. MGD.
The submitted project responds to community need for wastewater treatment to
serve development and protect water quality standards in on a watershed scale. A
detailed stormwater management plan protects the Eagle River from new
stormwater impacts, and the project will install a new sand/oil separator as part of
its site infrastructure. The facility is served by available utilities (e.g., electric, gas,
cable tv) and sufficient capacity exists for this expansion.
Attachment A
Avon WWTF 1041 Permit Application

p) The costs and benefits to the region and to the Town resulting
from the land use commitment necessitated or facilitated by the
proposed construction, expansion or modification of the SWWP
compared to alternative projected land uses in terms of land
suitability, community services, utilities and revenues;
Alternatives to this land use are not desirable at this site; it has served as a WWTF
for the Town since the 1966 and no additional land use commitment is required by
the proposed construction. The project exists within the existing property and land
use entitlements. The project cost is ultimately borne by the District ratepayers, as
described in detail in Section II b) 8) of this application; water quality of Gore Creek
and the Eagle River benefits from the nutrient upgrade project.
The project will result in enhanced water quality and support a watershed-based
nutrient management strategy. There are no alternative projected land uses for
this parcel or another parcel of land as uniquely suitable as the existing parcel.
q) Local and regional impacts of the proposed construction,
expansion or modification of the SWWP on water quality and water
resources, including effects on floodplains and wetland values
and functions;
The project will position the Avon WWTF to comply with applicable CDPHE water
quality requirements as described herein. Bypass flows will not impact the Vail
WWTF’s return flow obligations to Gore Creek, which are approximately 2 million
gallons day (MGD) during the snowmaking season. The flow obligation is triggered
if Gore Creek is below the instream water rights of 6 cubic feet per second (cfs),
which is most critical during the month of November (Carollo, 2017).
Proposed construction will employ best management practices conforming to Avon
requirements to protect water quality and water resources. The proposed nutrient
removal and capacity upgrades are done in compliance with the Clean Water Act
requirements to protect water quality and water resources. No wetlands or
floodplains are proposed for impact by the improvements proposed herein. A
detailed stormwater management plan has been developed for the project (Carollo
2019). The plan incorporates site specific BMPs designed to protect the Eagle
River from potential stormwater impacts. The plan identifies outfall locations, a new
sand/oil separator, and a new stormwater catch basin with a 4’ X 4’ grated opening.

r) Impacts of the proposed construction, expansion or modification
of the SWWP on sensitive, endangered or threatened species and
scenic, parks, recreational or other natural resources;
A complete Environmental Impact Report (EIR) was submitted with the application
and is included as Attachment F. Threatened and endangered species have been
evaluated, and no adverse impacts are anticipated as a result of this upgrade.
Scenic values have been addressed and improvements in materials and paint will
create a uniform campus appearance. New fencing and landscaping with
residential neighbors will mitigate scenic impacts of the expansion. The application
addresses impacts from waste, noise and odors. Impacts to the adjacent
recreation trail are not anticipated.
s) Impacts of the proposed construction, expansion or modification
of the SWWP on the character of adjacent or nearby
neighborhoods or development; and
After completion, the proposed construction will not significantly change the
character of the property, since it is currently an operating WWTF. The District and
the project team minimized impacts to the extent practicable.
Improvements to odor controls will result from the proposed construction. Noise
impacts from two new large format exhaust fans were modeled to minimize
impacts over ambient sound conditions. Odor controls were designed to improve
containment, detection and dispersion. In combination with new high velocity fans,
the expansion is an opportunity to improve odor impacts to neighboring properties.
Additional landscaping and screening are proposed to mitigate visual impacts to
neighboring properties.
The District will continue to coordinate temporary construction impacts with the
adjacent residential community (Lift View) to minimize neighborhood impacts.
Temporary project construction impacts expected are those typical to any jobsite
(dust, noise, parking). A temporary fence with noise dampening material will be
used to reduce construction noise along the property line shared with Lift View
condominiums. Plans for service deliveries of materials, temporary signage,
contractor/employee parking, and other aspects of construction including staging
plans will be developed by Moltz Construction. As previously mentioned, there will
be a very visible tower crane on the site for approximately 24 months.
These plans will be submitted to the Town as part of the building permit process.
The District and its contractors will maintain clear communication with Town
officials during the anticipated 32-month construction calendar, and the District will
report to Town Council on an annual basis as required in the 1041 regulations.

which requires routine sampling and monitoring. That plan will be amended upon
completion of the new stormwater infrastructure.
k) The SWWP promotes the efficient use of water.
Applicant Response: The proposal is for upgrades to nutrient removal at the Avon
WWTF; therefore, this criterion is not applicable. However, landscaping and on-
site water use is minimized and to the extent practicable, non-potable wastewater
effluent will be utilized for appropriate uses.
l) The existing wastewater treatment facilities or water treatment
facilities within the Town and which serve the service area must be
at or near operational capacity or will be within five (5) years from
the date construction of the SWWP is initiated, based on then-
current demographic trends.
Applicant Response: Planning for capital improvements at the Avon WWTF was
completed in 2017 as part of a Wastewater Facilities Master Plan Update. The
project is scheduled for completion within a 32-month construction schedule, as
agreed upon with staff of the State Water Quality Control Division to achieve
compliance with nutrient limits. While the expansion does not require an increase
in hydraulic capacity, the discharge limits for the new, upcoming permit is cannot
be met without the proposed improvements. Further, the organic loading requires
a re-rating to meet future organic loading conditions.
m) The proposed construction, expansion or modification of the
SWWP will not increase water pollution levels in violation of
applicable federal, state and local water quality control standards
and will result in no net loss of wetland values and functions;
Applicant Response: The project will not increase water pollution levels in violation
of applicable water quality standards; it is proposed to comply with new nutrient
limits, as described in detail herein. The project will dramatically reduce nitrogen
and phosphorous concentrations in the wastewater effluent. The decrease in
Attachment A

Page 70
nutrient loading to the Eagle River benefits instream water quality, including
biological and aquatic health. The project will not result in loss of wetland values
or functions, as none are identified or proposed for disturbance.
n) The applicant has the technical and financial ability to develop and
operate the proposed project in a manner that is consistent with
the permit conditions and the public health, safety and welfare.
Applicant Response: The District has technical and financial ability to develop and
operate the project in a manner consistent with all permit conditions, and the public
health, safety and welfare. A complete budget is included in Attachment L.
o) The nature and scope of the SWWP will not compete with existing
water or wastewater treatment services or create duplicative
services within the Town boundaries.

MEMORANDUM
TO: Matt Pielsticker, AICP; David McWilliams, AICP, Town of Avon
FROM: Jeffrey Schneider, P.E.
DATE: 1/29/2020
RE: Supplemental Information for Avon Wastewater Treatment Facility (WWTF)
Nutrient Upgrades Project Location, Character, and Extent Application.
ERWSD received a request for additional information to prepare the staff report for the Avon WWTF
Nutrient Upgrades Project Location, Character, and Extent application. The requested information
consisted of:
Before and after plan view
Landscaping and parking changes
Irrigation changes
Parking analysis – how many spaces for GFA
Lot coverage calculation
Lighting cut sheet
Roof pitch analysis
Color/Material Board
Each item is addressed in this memorandum, or where applicable, is attached to this memorandum.
1. Before and after plan view
Plan Sheets 01C02 (existing site topographical survey) and 05C01 (Overall site plan) are attached to this
memorandum as Exhibit A. In addition, a curated set of plan sheets consisting of General, Civil, and
Architectural is attached as Exhibit B which should simplify review of the documents.
2. Landscaping and parking changes
The site will undergo changes to the landscaping and parking configurations, mostly confined to the
western property line. In order to construct the planned improvements, the existing landscape island
along the western property line will be removed. Many of the trees will be removed; ERWSD has
approached Liftview with an opportunity to transplant certain pine trees on their property to help with
screening. The landscaping is proposed to be native seed areas with temporary irrigation for
establishment, as ERWSD attempts to limits consumptive outdoor water use to the extent possible. To
mitigate the loss of screening trees, a 10’ tall architectural fence is proposed. Plan Sheet 05A12 contains
a landscape plan and fence detail and is attached as Exhibit C.
3. Any irrigation changes
The site is currently irrigated with treated wastewater, in line with ERWSD’s policy of limiting outdoor
potable water use. We are anticipating a reduction in irrigated area, primarily along the western property
Attachment B
Supplemental Information for Avon Wastewater Treatment Facility (WWTF) Nutrient Upgrades Project
Location, Character, and Extent Application. Page 2 of 3
line of 8,811 square feet. In addition, the area to the southwest of the treatment facility will be reclaimed
with native seed and will require temporary irrigation. The reclaimed area will total approximately 11,950
square feet, with a net reclaimed area of 3,139 square feet compared to existing conditions.
4. Parking analysis – how many spaces for GFA
The Gross Floor Area of the wastewater treatment facility is not applicable to this project with respect to
parking. The existing treatment facility consists of 59,546 square feet, with the new expansion proposed
to be 24,648 sf, resulting in a total of 84,194 sf. Since the building contains wastewater treatment
process tanks and equipment, five operators staff the entirety of the 84,194 sf treatment facility. In
addition, the property contains approximately 7,652 sf of office and laboratory space and 7,480 sf of fleet
maintenance and vehicle/equipment storage. Per AMC 7.28.020, Government services, offices, and
facilities require 4 parking spaces per 1,000 sf of GFA. There are 45 designated parking spaces available
at the facility, not including the fleet maintenance parking area. The project proposes the addition of three
parking spaces along the north fenceline. Utilizing the office facility for parking calculations only, the AMC
requires 32 parking spaces. The facility will have 48 at the conclusion of the project, plus informal parking
areas throughout the facility.
The facility is a secured, gated facility and is not open to the public, save for scheduled appointments and
laboratory customers. In addition, the facility is home to ERWSD’s Field Operations division, with several
fleet vehicles occupying the facility. To mitigate parking impacts during construction, ERWSD is utilizing a
property at 32001 US Highway 6 in west Edwards to stage fleet vehicles and equipment during the long
project duration.
5. Lot coverage calculation
Lot coverage, as defined in AMC 7.08.010, means the ratio of the area of the site which is rendered
impermeable by buildings compared to the total area of a site, excluding those rendered undevelopable,
expressed as a percentage. Lot coverage on this site is somewhat misleading, as existing green spaces
contain buried process tankage. A portion of the buried process tankage will be removed and an 11,876
sf superstructure added for improved process control, access, and safety. Tables 5-1 and 5-2 below
show existing and proposed lot coverage areas.

6. Lighting cut sheet
ERWSD recently upgraded lighting at several of its facilities to high efficiency LED fixtures to reduce
energy usage in partnership with Holy Cross. The new construction will include exterior lights above new
doorways. The selected lighting is the ASD-WLP02A-30N50B, and a cut sheet is included as Exhibit D to
this memorandum. The fixture is full cutoff and is compliant with Avon’s dark sky ordinance.
7. Roof pitch analysis
A roof pitch analysis was not completed for this project due to the need to tie into existing rooflines and
adjacent buildings. The roof material is selected as precast concrete double tees. This roof is required to
span the large aeration basin tanks as it can support up to an 80-foot free span. The roof will be flat with
interior roof drains. Flat roofs enable the placement of HVAC and odor control equipment on the roof,
similar to other buildings on the property. More detail can be found in the architectural set of drawings
included as Exhibit B, specifically, sheets 05A03 to 05A10.
8. Color/Material Board
A Color/Material board will be provided at the Planning and Zoning Commission Meeting on February 4,

PO Box 975
Avon, CO 81620
Dear Mr. Pielsticker,
Thank you for the opportunity to provide comments on the proposed improvements to the Avon
Wastewater Treatment Facility (WWTF). Colorado Parks and Wildlife (CPW) has a statutory
responsibility to manage all wildlife species in Colorado. This responsibility is embraced and fulfilled
through CPW’s mission to perpetuate the wildlife resources of Colorado and to provide sustainable
outdoor recreation opportunities that educate and inspire future generations. CPW fulfills this mission
by responding to requests for comments on wildlife impact reports, land use actions, and consultations
through public-private partnerships.
After review of the application materials, CPW offers the following comments and recommendations:
The proposed improvements to the Avon WWTF occur largely on the existing facility footprint or
immediately adjacent to the existing site. Additionally, the Environmental Impact Report notes that the
development site lies outside on the established wetland zone, riparian zone and 100-year floodplain.
With the exception of the southern boundary along the Eagle River, the development site is surrounded
by historic anthropogenic disturbance and development. The development site itself lies within CPW
mapped range for a variety of big game and raptor species. Land use changes over the last several
decades have removed much of habitat value for big game species at and adjacent to this site.
Additionally, given the relatively urbanized nature of the site and existing development in the
surrounding area, CPW does not anticipate significant impacts associated with the improvements to the
Avon WWTF.
While the WWTF site does not lie in close proximity to mapped and active bald eagle nest sites, if eagles
were to establish nesting sites on or near the development site the following recommendations may
apply:
Minimize heavy equipment use and construction activities from October 15 - July 31 in order to
provide the bald eagles with time to fledge their chicks.
The proposed development site also lies within mapped human-bear and human-lion conflict areas and
human-bear summer concentration area. Additionally, human-bear conflict incidents have been
reported and documented in immediate proximity to the proposed development site. As such, CPW
emphasizes the proposed mitigation measures and offers the following recommendations:
Landscaping with wildlife in mind, to include avoiding the planting of fruit bearing vegetation.
Attachment C, page3
Dogs must be under control, either on a leash or under voice command.
All food (including pet food) should be kept indoors or in an IGBC-certified bear proof container.
No food waste should be left outdoors.
During construction, food waste and construction waste should be segregated into separate
containers.
All bear and mountain lion incidents should be immediately reported to CPW.
Minimize sediment contributions to the Eagle River. Apply appropriate best management
practices to minimize sediment transport during construction.
Colorado Parks & Wildlife values the opportunity to provide comments on this proposal. If you have any
questions or concerns, please reach out to District Wildlife Manager Devin Duval at (970) 930-5264.

RE: Avon Wastewater Treatment Plant Capital Upgrades
Dear Ms. Torres,
Thank you for the opportunity to provide comments regarding the Avon Wastewater Treatment
Plant upgrades 1041 permit application. While this project has merits that touch on multiple
issues, our comments pertain to anticipated project impacts to stream and aquatic ecosystem
health.
Eagle River Watershed Council (ERWC) advocates for the health and conservation of the Upper
Colorado and Eagle River basins, in order to protect and enhance the high-quality natural and
human values provided to our communities by rivers. Vigorously protecting our aquatic systems
ensures they can continue to provide numerous social, economic, and ecosystem benefits in
perpetuity.
The purpose of the Avon Wastewater Treatment Plant upgrades is identified as increasing overall
system treatment capacity and flexibility for Eagle River Water & Sanitation District’s (ERWSD)
three valley-wide facilities, extending the life of the Vail waste water treatment plant (WWTP) by
accepting increased effluent bypasses, and reducing nutrient discharges (measured as Total
Phosphorus and Total Nitrogen)
WATER QUALITY
The project is specifically designed to address treatment capacity issues, achieve ongoing
system-wide permit compliance, and improve water quality conditions on the Eagle River for both
the Avon location and the overall ERWSD system from Vail to Edwards by reducing nutrient loads.
In nutrient-poor mountain headwaters streams like the Eagle River, even small additions of
human-sourced nitrogen and phosphorus can promote eutrophic conditions that lead to
detrimental ecological impacts such as algal growth and macroinvertebrate community shifts
and imbalances that decrease populations of sensitive species like mayflies and stoneflies while
increasing populations of pollution-tolerant species such as worms, midges, etc. Associated
effects on prized local fisheries and recreation use may subsequently follow. Therefore,
reductions in nutrient loads to local streams are strongly supported by ERWC and the project is
anticipated to be a boon to aquatic communities downstream.
Attachment C, page7
ECOLOGICAL SETTING, HYDROLOGY AND FLOODPLAINS
The Eagle River in downtown Avon generally flows in a geomorphically confined river channel
with little available floodplain and a narrow strip of riparian vegetation zone that extends up
steeply sloped and erosion-resistant streambanks for 10 to 40 vertical feet. The channel at the
project site is no exception, running adjacent to the south parcel boundary for approximately 800’
and separated by the Eagle Valley pedestrian/bike path. Construction activities are not anticipated
to occur in any floodplain and riparian zones or alter existing floodplain heights and flood peak
elevations. Although redevelopment projects on river frontage often provide excellent
opportunities to restore, mitigate, or improve previous floodplain alteration and riparian
degradation, this site in Avon’s urban core does not provide such opportunities. The river corridor
here is heavily impacted already, and the project is unlikely to provide a net change in the negative
direction.
WATER USE AND INSTREAM FLOWS
As the nature of the permitted facility is specifically for water treatment, increases to
consumptive water use, and by extension, available instream flows for aquatic life, riparian health,
and recreational use are not expected. The shifting of treated effluent from discharging on Gore
Creek to Avon potentially decreases instream flows on segments of Gore Creek and the Eagle
River between these locations. Water volumes involved are relatively negligible throughout most
of the year but may be important to Gore Creek during extremely low baseflow periods. However,
ERWSD is aware of these issues in operational timing and has previously worked with their own
system operations as well as Vail Resorts (which diverts upstream of the Vail WWTP for
snowmaking) to ensure ecological streamflows are maintained in lower Gore Creek throughout
peak use demand periods and that lower Gore Creek does not develop an effluent-dominated
flow situation.
WATER QUALITY AND STORMWATER
The site plan has identified a mix of best management practices including new sand/oil
separators and a new detention basin. In general, quality of stormwater outflows should be
similar to or better than current site conditions.
CLOSING REMARKS
The Avon Wastewater Treatment Plant Nutrient Upgrades project is not anticipated to affect riparian
conditions, floodplain geomorphology, or instream flows. The specific purpose of the project is to
improve effluent quality by reducing nitrogen and phosphorus nutrient loads to receiving streams.
These actions should remain protective or improve instream water quality and by extension, aquatic
life conditions; ERWC is supportive of 1041 Permit approval for these actions.
If you have any questions regarding our comments, please contact us.

MEMORANDUM
TO: Matt Pielsticker, AICP, David McWilliams, AICP, Town of Avon
FROM: Jeffrey Schneider, P.E.
DATE: 1/29/2020
RE: Avon Wastewater Treatment Facility (AWWTF) Nutrient Upgrades Project
Responses to Referral Comments
Eagle River Water and Sanitation District was in receipt of three (3) referral responses for the Avon
WWTF Nutrient Upgrades Project 1041 application. Below please find our responses to each of the
referral items:
Referral 1: Colorado Parks and Wildlife, Dated January 15, 2020 from Devin Duval, District Wildlife
Manager
1. While the WWTF site does not lie in close proximity to mapped and active bald eagle nest sites, if
eagles were to establish nesting sites on or near the development site the following recommendations
may apply:
Minimize heavy equipment use and construction activities from October 15 - July 31 in order to
provide the bald eagles with time to fledge their chicks.
Response: As discussed with CPW staff, no bald eagle nest sites are mapped or observed on or near
the area, although potential habitat exists along the Eagle River corridor. Bald eagles are not likely to
select this location for nesting due to the existing disturbance and activity in the proximate area, including
the Westin gondola crossing the river about 1/3 mile upstream of the site. In the unlikely event that
eagles were to establish nesting sites on or near the development during the almost 3-year construction
period, the applicant agrees to work closely with CPW to identify potential mitigation, as practical.
2. The proposed development site also lies within mapped human-bear and human-lion conflict
areas and human-bear summer concentration area. Additionally, human-bear conflict incidents have
been reported and documented in immediate proximity to the proposed development site. As such,
CPW emphasizes the proposed mitigation measures and offers the following recommendations:
Landscaping with wildlife in mind, to include avoiding the planting of fruit bearing vegetation.
Response: No fruit-bearing vegetation is located on the site and none is proposed as part of the project.
Dogs must be under control, either on a leash or under voice command.
Dogs are not permitted on ERWSD properties.

All food (including pet food) should be kept indoors or in an IGBC-certified bear proof container. No
food waste should be left outdoors.
The project general contractor (Moltz Construction) has been informed of this requirement and the need
for bear proof containers has been added to the project construction specifications.
During construction, food waste and construction waste should be segregated into separate
containers.
The project general contractor (Moltz Construction) has been informed of this requirement and it has
been added to the project construction specifications.
All bear and mountain lion incidents should be immediately reported to CPW.
Comment noted, this information has been provided to ERWSD internal staff as well as the general
contractor.
Minimize sediment contributions to the Eagle River. Apply appropriate best management
practices to minimize sediment transport during construction.
The project has an extensive BMP program during construction and the general contractor will be
subject to a CDPHE Construction Stormwater permit and all conditions applicable thereto.
Referral 2: Eagle River Watershed Council, Dated January 20, 2020, from Holly Loff and Bill Hoblitzell
Response: ERWSD agrees with the findings of the letter and takes no exception. ERWSD is thankful for
the supportive letter as the intent of the project is to reduce human impacts to the Eagle River.
Referral 3: Eagle County, Dated January 15, 2020 from Maureen Mulcahy
1. How much additional energy will the expanded treatment process demand? The County would
like to understand increased demands in terms of both electricity and natural gas use as
compared to the overall plant to get an understanding of the scale of the improvements
relative to the existing facility.
Response: The connected load and the anticipated electrical demand of the Avon WWTP will be
essentially the same as before. In some areas, we are increasing the electrical load (i.e. adding HVAC to
the aeration basin building, adding mixers in the aeration basins, adding RAS pumps) and in some areas
we are reducing the electrical load (installation of lower horsepower IMLR pumps and reduced HVAC
load in the warehouse and equalization areas). We are not increasing the overall transformer capacity at
the facility. The natural gas usage on site will match current conditions. Some HVAC equipment is being
added that will increase loads (i.e. heating the aeration basin and new clarifier building), but significant
changes were also made to reduce air changes and thus natural gas usage in the warehouse and
equalization areas. The site is limited as to its natural gas service available, and when combined with
ERWSD’s sustainability goals, no additional gas usage is anticipated. Further, the project team is
currently re-evaluating HVAC equipment with respect to utilizing natural gas on this project and all other
capital projects.
2. The application details energy efficiency components incorporated into the project design,
including use of efficient aerators and proper pipe sizing to reduce energy consumption. How did
energy efficiency factor into the decision making process when selecting the proposed treatment
train? What, if any, additional energy efficiency measures will be incorporated into the design?
Attachment C, page10
Avon Wastewater Treatment Facility (AWWTF) Nutrient Upgrades Project Responses to Referral
Comments Page 3 of 4
Please include deemed savings estimates for such measures as a percentage of the forecasted
additional energy use if possible.
Response: The evaluation for selection of the proposed treatment train included capital cost, O&M cost
(which included an estimate of energy requirements), safety, odor, visual, noise, and traffic. This
evaluation is documented in TM 7 of the 2017 WWTF Master Plan Update. Energy efficiency was not a
major deciding factor in selection of the treatment train. Rather, the proposed treatment train was
selected due to its ability to flexibly, reliably meet the discharge permit.
Energy efficiency measures incorporated into the design include the following:
a. Use of energy recovery on Makeup Air Unit to provide air to air heat recovery, minimizing
natural gas use.
b. Use of a VFD in the Makeup Air Unit to maintain an adjustable negative space pressure
that can appropriately respond to variation in aeration air from the aeration basins.
Reduces excess outside air infiltrating into the space that would lead to more energy
usage and less indoor temperature control.
c. New HVAC design to eliminate the no longer required continuous 100% outside air
ventilation systems for the EQ Building and the Warehouse Building.
d. Proper design/sizing of the HVAC systems in the aeration basin and secondary clarifier
buildings to provide sufficient air changes for operator safety but not so much that we pull
in excess (cold) outside air.
e. Use of VFDs on new IMLR, RAS, and EQ pumps to allow for reduced energy
consumption at turndown flows.
f. Increased pipe sizing in some locations to reduce system head loss and pump
horsepower (i.e. IMLR system)
g. Elimination of WAS pump and secondary scum pumps, allowing for gravity flow to
Edwards WWTF.
h. Replacement of existing blowers with higher efficiency blowers (around 15% increased
efficiency).
i. Sizing of blowers and aeration system design to reduce need for air blowoff at diurnal low
flows.
Include deemed savings estimates as a percentage of forecasted additional energy use
Response: Energy use at the facility is not anticipated to substantially increase as part of this project, as
noted in the response to Question 1.
3. Please describe resource recovery elements integrated into the project design, including any
impacts to the existing heat recovery system capacity and ability to recover phosphorus.
Response: The ability to connect heating loads to the existing heat recovery system was explored during
the design phase but was deemed infeasible due to the distance (and energy) required to pump heated
water throughout the facility and the required retrofit of make up air units to function with hydronic heating
units. The proposed makeup air unit includes air-to-air heat exchanger that recovers up to 70% of the
heat in the system. ERWSD is completing a facilities master plan to replace and improve its aging
facilities on the eastern portion of the site and is planning on utilizing the heat recovery system for that
future project.

This project will increase the ability to for phosphorus to be recovered in the future at the Edwards
WWTF. As part of this project, phosphorus will be removed biologically from the liquid stream and
transferred into the solids stream. Solids handling was decommissioned at Avon WWTF in 2015 and all
solids are processed at a consolidated digestion facility at the Edwards WWTF. Solids produced at Avon
are conveyed through the collection system to Edwards. Similarly, the Vail WWTP removes phosphorus
biologically, sending the solids down to Avon and ultimately to Edwards. In the future, phosphorus could
be recovered from the solids at Edwards (which would include the phosphorus from all three facilities)
using the CalPrex process to precipitate brushite (calcium phosphate). This product can be marketed as a
fertilizer. ERWSD currently has nutrient-rich Class A biosolids available for public use at its Biosolids
Containment Facility adjacent to the Eagle County Landfill.
4. Figure 25 in the application presents growth projections from Stan Bernstein and Associates.
Please share this growth study as the County would appreciate the opportunity to review the
growth projection report in its entirety to understand the assumptions upon
which the projections are based.

February 4, 2020 PZC Meeting – Railroad Bridge Sign
Staff Report – Sign Design - Public Hearing
February 4, 2020 Planning & Zoning Commission Meeting
Project Name: SGN20001
Zoning: Right of Way
Address: Rail Bridge Over Avon Road
Location: Prepared
By:
Benchmark at Beaver Creek
David McWilliams, Town Planer
Staff Report Overview
This staff report contains one application for consideration by the PZC: Sign Design for new Embedded
Messaging Center (EMC) Light Emitting Diode (LED) signs on the railroad bridge above Avon Road.
Summary of Request
The Town of Avon is proposing to place new EMC signs in the location where event signs are currently
located from time to time. The current signs are located to face oncoming traffic from above.
The new signs (Attachment A) are approximately as large as the current banners are allowed to be.
Current application criteria for the banners require a non-profit sponsor, allow signs for a maximum of
one (1) week, from Monday to Sunday, with a $150 fee to be displayed on each side of the bridge.
Further, no hand-drawn words (copy) are permitted, and sponsor names and logos may cover no more
than twenty percent (20%) of the total banner space.
There is no proposed limit to hours or brightness for the new signs. Avon Municipal Code requires,
“Such signs shall be equipped with automatic dimmers, which shall be programmed to not exceed three
tenths (.3) footcandles over ambient light levels.” A footcandle is the illuminance of one lumen on a
one-square foot surface with a uniform distribution. A standard 40-watt lightbulb produces puts out
450 lumens. This is a standard adopted by several states and municipalities.
The time limit is proposed to change to be more flexible. For example, the board could read “Avon
LIVE! tonight” on Wednesdays and “Rodeo tonight” on Thursdays during the summer, instead of
having the weeklong time frame. Signs are not proposed to run simultaneously, and only one message
will be allowed at a time.

Northern facing sign location.
Review Criteria
The Planning and Zoning Commission shall consider the following items in reviewing proposed
designs:
1. Evidence of substantial compliance with the purpose of the Sign Code as specified in
Section 7.32(A) Sign Code Purposes;
Staff Response: The application strikes a balance for criterium (4): “Promote high quality and weather
resistant signs that are properly maintained over time and renovated when necessary.” Taken in context
as a replacement for temporary signs, the proposal saves time, labor and materials over the long run,
and is safer.
PZC should carefully weigh if the proposal meets (7): “Provide a reasonable balance between the right
of an individual to identify a business or express a message, and the right of the public to be protected
against the visual discord resulting from the unrestricted proliferation of signs and similar devices.”
Additional illuminated signs in this location may be viewed as visual clutter and PZC is instructed to
carefully determine if the proposal meets these purposes.
2. The suitability of the improvement, including materials with which the sign is to be
constructed and the site upon which it is to be located;
Staff Response: The material choice of the sign are stock choices meant to protect the display with an
iron frame. Planning staff is not aware where power will be drawn from or what the conduit will look
like.
3. The nature of adjacent and neighboring improvements;
Staff Response: Neighboring buildings include the Burger King, Christy Sports, and the White River
Center. The sign types are diverse but generally present a unified design of auto-centric internally
illuminated signs.
4. The quality of the materials to be utilized in any proposed improvement;
Staff Response: Staff anticipates a more uniform aesthetic with the LED panel compared to an array
of banner types.
5. The visual impact of any proposed improvement, as viewed from any adjacent or
neighboring property;
Staff Response: The visual impact should be carefully assessed by PZC.
6. The objective that no improvement will be so similar or dissimilar to other signs in the
vicinity that values, monetary or aesthetic, will be impaired;

Staff Response: Not applicable.
7. Whether the type, height, size and/or quantity of signs generally complies with the sign
code or sign program, and are appropriate for the project;
Staff Response: The application allows for individuality while maintaining consistency of size and
location.
8. Whether the sign is primarily oriented to vehicular or pedestrian traffic, and whether
the sign is appropriate for the determined orientation.
Staff Response: PZC should carefully weigh if the LED application is appropriate for this location.

TO: Avon Planning and Zoning Commission FROM: Eric Heil, Town Manager
RE: Bridge Signs – Avon Road
DATE: January 31, 2020
SUMMARY: This report provides additional information for the Town’s application to erect event information
signs on the Union Pacific Railroad Bridge (“Bridge”) on Avon Road.
Avon installs event banners on the Bridge each year to announce and advertise events in Avon and
Beaver Creek, including the Vilar Performance Center. The process to install banners requires four public
works crew members, the use of the bucket truck and the closure of one lane of Avon road. The process
requires approximately two hours or the equivalent of a full public works labor day. We estimate that 15 to
20 banners are currently installed throughout the calendar year. Each banner costs approximately $120 to
$150 and typically goes to the County landfill after use. The electronic sign will have a wireless connection
and can be programmed remotely.
Avon has more events planned for the 2020 calendar year compared to 2019 and will likely have
additional events in 2021. Between music, arts and cultural events, Avon plans to produce or host over 30
events in the 2020 summer season. In addition, Avon seeks to increase partnership relationships with
Beaver Creek, including the advertisement of the Beaver Creek Rodeo in Avon, Beaver Creek events such
as Brews and BBQ, events at the Vilar, and Birds of Prey. Announcement and advertisement of Beaver
Creek events will likely add up an additional 30 event postings throughout the year. The installation of an
electronic sign will allow Avon to easily and conveniently to post event announcements and advertisements
throughout the year.
The proposed high-resolution sign is intended to allow posting of event signs in an attractive manner
that utilizes full color art work similar to the current banners. The use of the event sign is planned and
intended to post only static signs, meaning multiple message postings that rotate are not intended. An
example of rotating messages is the Town of Dillon electronic sign that has three screens that rotate every
four seconds.
No commercial advertising is planned for the Bridge signs other than special events open to the
general public in Avon and Beaver Creek. The intent is to use the Bridge signs exclusively for
announcements of public special events, occasional public messages (such as wildfire mitigation in spring),
and for emergency announcements if needed.
The location and use of the Bridge signs were also selected for consideration to traffic safety and
aesthetic concerns. The Bridge banners are located on a stretch of Avon road without intersections or
pedestrian crossings. As stated above, the intent is to post static signs that are similar to the banners but
allow for changing as often as appropriate to announce events that day or the next upcoming event. We are
also revisiting all signage on Avon Road with consideration towards not distracting drivers or creating sign
clutter (or better yet, reduce existing sign clutter).
The Avon Town Council included the proposed electronic Bridge signs in the adopted 2020 Budget and
Capital Improvements Plan with the intent to facilitate special event announcements and community
engagement. The Bridge signs are expected to allow at least 60 event announcements in 2020, which
represents the equivalent of 60 total public works labor days and an equivalent cost of $7,200 per year.
Thank you, Eric
