RE:
Planning Commission Members — Employment Relationship
DATE:
October 15, 2015
SUMMARY UPDATE: I presented a Written Report via Memorandum to the Avon Town Council dated
Oct 9, 2015. The Avon Town Council discussed this topic at the Council meeting. Council directed me
at its regular meeting on October 13, 2015 to prepare an ordinance that would disqualify both Council
members as well as Planning Commission members that have an employer-employee or employment -
supervisor relationship. I plan to introduce an ordinance for first reading as early as the October 27,
2015 Council meeting. Once such an ordinances passes and takes effect (30 days after second
reading) Planning Commission members with an employer-employee or employment supervisor
relationship will become disqualified (meaning both such Planning Commission members would
become disqualified) and those seats would be deemed vacant.
I am available to answer any questions regarding Council's direction on this matter.
Thank you, Eric

MEMORANDUM
TO:
Honorable Mayor Fancher and Avon Town Council members
CC:
Avon Planning Commission, Matt Pielsticker, Senior Planner
FROM:
Eric J. Heil, Town Attorney
RE:
Planning Commission Members — Employment Relationship
DATE:
October 9, 2015
SUMMARY: This memorandum notifies Council that two Planning Commissioners have an
employment relationship and provides an opinion that such relationship is not a violation of the Town
Code of Ethics. Commissioner Chris Lubbers recently took a position with ECO Transit which is a
supervisor position in relationship to Commissioner Jared Barnes, who also is an employee with ECO
Transit.
ETHICS CONSIDERATION: The Avon Town Code of Ethics defines a Town officer to include anyone
holding a position by appointment in service of the Town, which includes Planning Commission
members. The Avon Municipal Code ("AMC") Sec. 2.30.060 lists specific actions which constitute a
conflict of interest. There is no explicit restriction against two Planning Commission members having
an employment relationship. Conflicts of interest are focused on the receipt of a financial benefit in
return for an official action. An employment relationship in itself would only create a conflict of interest
if the appointed official in a supervisor position attempted to use the status of the subordinate's
employment to influence the official act of the subordinate. The Town Code of Ethics also specifies
that it is a conflict of interest to perform an official act that gives rise to the appearance of impropriety.
AMC Sec. 2.30.090 states that a Planning Commission member may raise the question of a conflict of
interest and the Planning Commission as a body then determines if a conflict of interest exists.
Although Commissioners Barnes and Lubbers have disclosed the employment relationship there has
been no question raised by any Planning Commission members to ask the Planning Commission as a
body to consider whether this employment relationship constitutes a conflict of interest. It is my opinion
that this employment relationship in itself does not constitute a conflict of interest under the Town Code
of Ethics. Such a general finding does not restrict the Planning Commission from considering whether
a conflict of interest exists with regard to a particular action or matter in the future.
OTHER CONSIDERATIONS: Planning Commission members Barnes and Lubbers are reminded that
restrictions on ex parte communications apply and that they are advised to refrain from discussing any
pending development applications while in their work setting. Finally, any planning matters that involve
ECO Transit will necessarily require both Commissioners Barnes and Lubbers to disclose a conflict of
interest and not participate in any discussion or action on such matter.

Staff Report -Special Review Use Avon
October 20, 2015 Planning & Zoning Commission Meeting
COLORADO
Case #SRU15003
Project type Special Review Use
Legal description Lots 2 & 3, Block 1, Benchmark at Beaver Creek Subdivision
Owner G.P.I. Partners, PO Box 99, Vail, CO 81658
Zoning Neighborhood Commercial (NC)
Address 111 Nottingham Road, Avon, CO 81620
Prepared By Brian Garner, Town Planner
Summary of Request
Matt Morrison representing Wilcon Energy (Applicant) is requesting a Special Review Use (SRU) Permit
to allow the use of a commercial propane Autogas dispenser on a small portion of an existing parking
lot used by Northside Coffee & Kitchen. The property is zoned Neighborhood Commercial (NC) and is
located on Lots 2 & 3, Block 1, Benchmark at Beaver Creek Subdivision addressed as 111 Nottingham
Road (The Property). The improvements are proposed to include an underground propane storage
tank, a single above -ground fueling dispenser with protective bollards, and signage.
Site Analysis
Lot 2 is developed as a parking lot for customers of the Northside Kitchen consisting of asphalt
pavement, thirty (30) striped parking stalls, and landscaping on the northern two-thirds (2/3) of the lot.
Parking stall dimensions are 9'x18', according to the plans on file with the Town. The property is
relatively flat with a slight grade to the southwest (for drainage into detention pond) and the asphalt is
in good condition. The southern one-third (1/3) of Lot 2 remains in natural condition, vegetated with
natural grasses, and contains a small water quality detention pond. As shown on the submitted plans,
the fuel dispenser is proposed to be located just off the edge of asphalt parking area adjacent to two (2)
existing, perpendicular parking stalls at the southwest corner of the parking area. The dispenser would
be installed on an approximate 4'x 4' concrete pad located several feet north of two existing evergreen
trees and would not displace any existing landscaping. There is currently no site lighting and none is
proposed with this Application, although the fuel dispenser does have an electronic display and some
internal lighting. The Applicant proposes to install the underground fuel tank, containing 1,000 gallons
capacity south of the dispenser. Finally, concrete bollards would be placed at the corners of the
concrete pad for protection of the dispenser unit. This location is ideally situated to minimize disruption
to snow removal and storage.
Lot 3 is undeveloped and is vegetated with native grasses. The site plan indicates potential underground
utilities in the vicinity and the Applicant will need to verify the location of utilities prior to installation of
any fueling station equipment. Power for the dispenser unit will come from an existing electric utility
box on Lot 3.
Parking and Traffic
The Northside Kitchen parking lot use was approved in perpetuity by a Special Review Use in 2013
through Resolution 13-02. The parking lot contains 30 paved and striped parking stalls available to
patrons of the Northside Kitchen, while a striped crosswalk provides a safe crossing of Nottingham
Road. Lot 2 is accessed by a single driveway with full movement ingress and egress. The proposed
October 20, 2015 PZC Meeting —Case #SRU15003
propane fuel station should have a minimal impact to the parking since the lot is primarily used as
overflow parking and is rarely parked to capacity. As shown on the site plan, one parking stall would be
reserved for refueling operations, chosen so a refueling truck can pull straight in to the stall, and back
out with little conflict. Both parking stalls are proposed to be designated for the exclusive use of fuel
customers and would be signed as such.
Zoning
The Property is zoned Neighborhood Commercial (NC) and the proposed use is not specified in the list
of allowed uses contained in Table 24-1 of the Avon Development Code. The most similar listed use is a
convenience store with fuel which is designated as a Special Review Use in the NC zone district.
Accordingly, a determination was made by staff to make the Application eligible for consideration
through the Special Review Use permit process.
According to the Development Code, the NC zone district "is established to provide for a compatible
mix of residential, small-scale neighborhood -serving commercial and civic uses." The adjacent Conoco
and Shell gas stations are zoned Neighborhood Commercial as is the Avon Auto & Truck repair shop
located west of the subject property on Lot 4. These adjacent uses received SRU permits to operate
accordingly.
A Special Review Use is regulated in Sec. 7.16.100 of the Avon Development Code. According to the
purpose statement for this Section: "This Section provides a discretionary approval process for special
review uses that have unique or widely varying operating characteristics or unusual site development
features. The procedure encourages public review and evaluation of a use's operating characteristics
and site development features and is intended to ensure that proposed use will not have a significant
adverse impact on surrounding uses or on the community at large. Special review uses that may be
allowed in each zone district are listed in Table 7.24-1, Allowed Uses."
Comprehensive Plan Analysis
Lots 2 & 3 are located within the Nottingham Road Commercial District of the Town of Avon
Comprehensive Plan. Specific Land Use Policies identified in the Comprehensive Plan that support this
application include:
• Policy G.1.14: Enhance air quality by implementing an alternative fuel program for the Town's
transit and fleet vehicles.
• Policy H.3.1: Reducing the number of air pollution sources to the greatest extent possible, by
limiting the number of fireplace installations, reducing demand for automobile trips, and
reducing pollution from existing sources through the use of alternative fuels, scrubbers, and
other technologies.
Review Criteria
A Special Review Use application must meet the criteria set forth in Sec. 7.16.100 of the Avon
Development Code as follows:
(1) The proposed use is consistent with the Comprehensive Plan and all applicable provisions of this
Development Code and applicable state and federal regulations;
Staff Response: The proposed use achieves certain goals of the Avon Comprehensive Plan by permitting a
commercially -accessible alternative fuel dispensing station, upon determining the use is compatible with
adjacent and surrounding uses. The Applicant is required to obtain any required State approvals for all
aspects of the operation, including, but not limited to the State of Colorado Division of Fire and Life Safety,
October 20, 2015 PZC Meeting —Case #SRU15003
Eagle River Fire Protection District, and the Colorado Division of Oil and Public Safety. Lastly, the Applicant
is generally compliant with applicable provisions of the Avon Development Code.
(2) The proposed use is consistent with the purpose and intent of the zoning district in which it is
located and any applicable use -specific standards in the Development Code;
Staff Response: Staff has determined that fuel dispensing may be permitted as a special review use in the
NC zone district, if approved by the Planning & Zoning Commission. Uses permitted in the NC zone district
are intended "...to provide for a compatible mix of residential, small-scale neighborhood -serving
commercial and civic uses." Use -specific standards in the Development Code pertain mostly to gasoline
service stations that contain multiple fuel dispensers under a canopy. Sec. 7.24.06o(h)(3) reads:
(3) Gasoline/fuel stations:
(i) A fuel pump canopy shall utilize the same architectural design and materials as the principal
building on the lot.
(ii) Light fixtures mounted under canopies shall be cut-off and shielded so that there is no glare or
light spillage at the property line. Lights and fixtures shall not extend below the surface of the
ceiling of the canopy.
(iii) Lights shall not be mounted on the top or sides (fascias) of the canopy and shall not be
externally illuminated, except as part of an internally illuminated sign that meets the standards
of Chapter 15.28, Sign Code.
Though the proposed use is similar in context to the use -specific criteria for gasoline/fuel stations, this
application does not contemplate a full-service station with a drive-thru canopy. In lieu of utilizing these
standards, staff is recommending several conditions should the PZC approve the Application.
(3) The proposed use is compatible with adjacent uses in terms of scale, site design, and operating
characteristics;
Staff Response: The fuel dispenser is proposed to be located within a developed parking lot, adjacent to
undeveloped property on the west (Lot 3). An automotive repair shop is located adjacent to the west side
of Lot 3, the undeveloped lot. A Shell gasoline station is adjacent to the east; the intersection of
Nottingham Road & Swift Gulch Road is adjacent to the north; additional undeveloped land is located to the
south, adjacent to a public trail system and Interstate 7o right-of-way. The use should be compatible with
and not negatively impact other adjacent uses, which are similar in nature.
(4) Any significant adverse impacts (including, but not limited to, hours of operation, traffic generation,
lighting, noise, odor, dust, and other external impacts) anticipated to result from the use will be
mitigated or offset to the maximum extent practicable;
Staff Response. Staff has worked with the Applicant to mitigate concerns with siting and use logistics and
the use is furthermore regulated by state agencies. The dispenser contains minimal lighting and does not
produce noise or vibration. Odor is expected to be about the same as a standard gasoline fuel pump, and
the use will be isolated from adjacent uses, with the exception of parking patrons. Since the use is
commercially available, the fuel dispenser will be available 24 -hours, which is not expected to conflict with
on-site or adjacent uses.
(5) Facilities and services (including sewage and waste disposal, water, gas, electricity, police and fire
protection, and roads and transportation, as applicable) will be available to serve the subject property
while maintaining adequate levels of service for existing development; and
October 20, 2015 PZC Meeting —Case #SRU15003 3
Staff Res onset The proposed fuel dispenser is located within an existing developed property that
currently has availability for all utilities, police and fire protection. The proposed single fuel dispenser
requires only electric service and should have a negligible impact on these utilities and services.
(6) Adequate assurances of continuing maintenance have been provided.
Staff Response: The Applicant is proposing daily monitoring of fuel levels and monthly inspections of the
site, including all hoses and emergency prevention devices. Additionally, the Applicant is proposing the use
of Professional Emergency Resource Services, a 24-hour emergency response company to monitor the
equipment.
Staff Recommendation
Staff recommends approval of case #SRU15003 with conditions.
Conditions
1. Prior to beginning any construction, the Applicant's contractor shall contact all appropriate
utility companies for line locations, and contractor shall then locate all utilities (including depth)
The Applicant shall submit the locate information with the building permit application.
2. The Applicant shall restore any landscaping to pre-existing conditions if disturbed.
3. The Applicant shall restore any aspect of the property altered or damaged by the facilities or use
on Lots 2 & 3 upon removal of any equipment to conditions pre-existing the installation to the
satisfaction of the Town and the property owner. The Applicant shall photo -document
conditions before equipment installation and confer with Town staff prior to the removal of any
installed equipment to agree on the restoration plan.
Recommended Motion
I move to approve the Special Review Use permit proposed in Case #SRU15003, an application to allow a
commercial propane fueling station, with three (3) conditions and three (3) findings as presented in
Staff's report.
Findings
1. The Application was reviewed in accordance with Sec. 7.16.1oo Special Review Use and
determined to be eligible for consideration with the applicable review criteria.
2. The proposed use has a negligible impact to adjacent or on-site uses and confers a benefit to the
greater community by providing a commercially accessible source of alternative fuel that is
better for the environment.
3. The proposed use is compatible with adjacent uses in terms of scale, size and scope and any
possible impacts will be minimal and mitigated by constant monitoring and safety inspections,
as agreed by the applicant.

ENGINEER SO THAT MINOR LINE OR GRADE CHANGES CAN BE MADE TO
ELIMINATE ANY CONFLICTS WITH THESE EXISTING UTILITIES.- ALL EXISTING
UTILITIES SHALL BE PROTECTED FROM DAMAGE BY THE CONTRACTOR.
UTILITIES THAT ARE DAMAGED BY THE CONTRACTOR THAT WERE PROPERLY 0
MARKED/LOCATED SHALL BE REPAIRED BY THE CONTRACTOR AT NO EXPENSE
TO THE OWNER OR ENGINEER.
7. VERIFY THAT RAISING THE EXISTING SEWER RIM WILL NOT MAKE THE
DISTANCE FROM RIM TO FIRST STEP GREATER THAN 1'-911. IF IT DOES, A NEW n
BARRELL SECTION WILL BE REQUIRED RATHER THAN GRADE RINGS.

Brian,
All of the specifications regarding the safety and installation of this dispensing station are based upon
NFPA 58. 1 have contacted the Eagle River Fire Protection District and have received the blessing of Gail
McFarland (Assistant Fire Marshall) and Shane Kakavas State of Colorado(Fire & Life Safety Section), as
well as Wayne Reinert (Colorado Division of Oil and Public Safety).
I have attached photos of how the signage will look at the lot. We will not have to restripe the lot as we
are only going to be taking up two(2) parking spaces that you can see I have highlighted in the attached
diagram.
The tank will be buried, so we will not have to provide any added protection for it, the only requirement
is that it is buried at least bin below the grade level, as for the dispenser it -self, I will have bollards
placed around the tank for crash prevention. The hoses attached to the dispenser will be 18ft long, so
we will have plenty of room to re -fuel any size vehicle.
As for the daily use of this facility, I assume that on the conservative side we will be able to convert 3-4
vehicles/ month. These vehicles should be utilizing this station about 2-3 time/week. Taking these #'s
further out, by this time next year we will have 40 vehicles converted to run on propane, that will be re-
fuelling 2-3 times/week. So we will not be adding to the traffic flow in this area, if anything we will be
taking away some of the congestion at the other two stations.

To: Chairman Jim Clancy and Planning and Zoning Commission
From: Matt Pielsticker, Planning Director
Date: October 15, 2015
Agenda Topic: Other Business — Eagle Valley Trail Phase 3 Retaining Walls
Introduction
Town Staff is seeking input on the retaining wall design for the Phase 3 of the Eagle Valley Trail,
scheduled for construction in 2o16. This is a work session, and action is scheduled for your November
3, 2015 meeting. Justin Hildreth, Town Engineer, will be attending to answer questions. The plan
sheets, wall profiles, and color photographs of the proposed wall design are attached for your review.
Eagle Valley Trail, Phase 3
Phase 3 of the Eagle Valley trail runs from Beaver Creek to Stonebridge Drive and is the last segment
of the trail in Avon to be completed. It has not been completed because it is the most difficult and
expensive as a result of the large amount of retaining walls required. The project budget is $2.75M,
and is funded by Colorado Department of Transportation, (CDOT), ECO Trails, and the Town of
Avon. Phase 1 and i were constructed last year and extends from Hurd Lane to Beaver Creek and
includes bridges over the Eagle River and Beaver Creek.
There will be four walls and they are up to 14 FT tall, 1,316 FT long, and 13,733 SF as depicted on the
attached plan and profile sheets. The walls will be constructed of large Redi-Rock blocks with the
Ledgestone face and treated as shown on the attached cut sheet. The walls were designed by an
Engineer specializing in retaining walls and have been approved by CDOT's structural division. The
Ledgestone face and color were selected because the color blends with the local environment and the
treatment matches the local rugged topography. The design has been vigorously reviewed to
minimize the quantity, particularly because of their large cost. The requirement of the walls was
dictated by the steep terrain, US6, wetland and riparian vegetation, and the Eagle River.
They will be located on property owned by the Town of Avon, Eaglebend Affordable Housing Corp and
the Highway 6 right-of-way. An easement was obtained last year from Eaglebend to allow the
construction of the wall and trail. CDOT will issue a Special Use permit to allow for the construction of
the trail when a contractor has been selected.
Avon Development Code Requirements
7.28.07o Retaining Walls
(a) Purpose. The general intent of the retaining wall standards are to reduce the
necessity for excessive grading and encourage stepping of driveways and buildings with the
natural grade.
(b) Standards
(1) Retaining walls may be utilized only where finished grades cannot meet the
October 15, 2015 PZC Work Session Eagle Valley Trail Retaining Walls
PAGE1OFz
recommended standards of this Development Code due to naturally occurring
topography and other site development constraints.
(2) Retaining walls over four (4) feet in height shall be designed with a series of retaining
walls with landscaped terraced steps. The width of the terrace between any two (2) four
(4) foot vertical retaining walls shall be at least three (3) feet. Retaining walls higher than
four (4) feet shall be separated from any other retaining walls by a minimum of five (5)
horizontal feet. Terraces created between retaining walls shall be permanently
landscaped.
(3) A retaining wall shall not exceed seven (7) feet in height unless approved by the PZC
and it is demonstrated that no alternative site layout is functional.
(4) The design of retaining walls shall be constructed of materials compatible with the
site and materials of the structures on the site. Retaining walls and cribbing should
utilize natural materials such as boulders, cut rocks, stone -veneer, or textured, color
tinted concrete. Timbers and railroad ties are prohibited as retaining wall materials.
Where two (2) alternatively designed retaining walls meet, a cohesive transition between
walls must be demonstrated.
(5) Walls over four (4) feet in height or any wall supporting a vehicle load or structure,
shall be structurally designed and certified by a Colorado licensed professional engineer.
Next Steps
Given the conflict with standard (2) above, an Alternative Equivalent Compliance application must
accompany a Minor Development Plan application for the proposed wall design. The extensive site
analysis conducted by engineering to minimize retaining wall use appears to satisfy standard (3).
Staff would like to answer any questions PZC may have at your October 2oth meeting; a public hearing
to consider the walls would be presented on November 3rd

1.0 GENERAL
All subsurface soil parameters, assumed soil contact areas, and groundwater parameters
used in the design were based on the borings presented in the report by Michael W. West &
Associates titled "Geotechnical Services for ECO Trails Phases 1 and 2, Avon to Eagle—Vail,
Colorado" dated November 30, 2011.
Description
A. Work includes furnishing and installing the segmental retaining wall (SRW) units to the
lines and grades shown on the plans and as specified herein. Also included is
furnishing and installing appurtenant materials required for construction of the
complete system. The wall design shall accommodate the existing utilities without
adjustment unless noted on the plans.
B. The CONTRACTOR is responsible for determining the locations of any underground utilities prior to
construction of the wall.
C. The Contractor shall provide temporary shoring if required to construct the retaining
walls. This cost is incidental to the work and is not paid for separately.
D. The contractor is solely responsible for safety. The Engineer and Owner shall not be
responsible for means or methods of construction or for safety of workers or of the
public.

D. Gravity Block Quality Control, Placing Plan and Daily Placement Logs. Before the start
of each wall construction, the Contractor shall provide a block—placing plan and shall
supply daily placement logs to the Engineer weekly and at the completion of the
wall. The daily placement log shall consist of an elevation view of the wall showing
the dates, number of blocks placed, and the lot numbers of the blocks The block
quality control shall contain multiple submittals if required. Blocks shall be labeled
with the manufacturer'fs lot number for each shipment and corresponding
certification with one set of random samples tested for each 1,000 blocks. At least
one certification with supporting test results is required for each wall. Test results
shall be reviewed and pre—approved by the Engineer before shipment.The Engineer
may conduct separate tests with the spared coupons from the original samples.
Block testing shall be increased to one set of sampling for every 500 blocks if the
Engineer identifies substandard blocks or when block color or concrete mix changes.
With the Engineer'fs approval, block sampling may be reduced to one set of
sampling for every 2,000 blocks after the first acceptable sampling results. The
blocks used for Engineer'fs verification purposes shall be a maximum of 0.5 percent
of the total number of blocks. The Engineer will conduct block sampling as early as
possible and acquire blocks regularly. However, when tests are not performed within
90 days of the sampling date, the blocks will be returned untested. The Contractor
shall coordinate and mark the block and backfill placing sequence on the daily
placement logs. The log serves as means for the Engineer to identify where each lot
of blocks was placed.
E. Wall with Curved Alignments, Tight Curved Corners, and Sections Adjacent to Bridge
Abutment. The Contractor shall provide a placement plan that shows curved layouts,
special block or saw cut block dimensions, sequence of block placement, and
construction off—sets as recommended by the Manufacturer. For tight curved corners,
8 foot radius or less, and dissimilar foundations such as bridge abutment, to avoid
blocks with random cracks, the Contractor shall install stack bond blocks with
vertical slip joints, if necessary, as shown on the plans. A vertical slip joint for
stress relief may be built either with pre—cut or partial pre—cut individual blocks or
by saw cutting block face of breaking running bond vertically right after installation.
F. Excavation and Foundation Preparation.The Contractor shall report to the Engineer
in writing density test results for any unsatisfactory bearing material not
meeting the minimum 95 percent of standard Proctor per ASTM D698. If the
excavation for the placement of the leveling pad exposes an unsatisfactory
bearing material, the Engineer may require removal and replacement of that
material. The Engineer will provide the limits including the depth of removal.
4.0 CONSTRUCTION OF THE WALL SYSTEM
Excavation and Foundation Preparation
A. Foundation soils shall be excavated as required for installation of the retaining wall system
as shown on the plans. Excavate to the base level for a sufficient distance behind the
face to permit installation of the leveling pad.
B. Foundation soil shall be observed by the Geotechnical Engineer to confirm that the bearing
soils are similar to the design conditions or assumptions. Any unsuitable material shall
be excavated and replaced as directed by the Geotechnical Engineer.
C. The native foundation soil shall be compacted to a minimum of 95% maximum dry
density as determined by a Standard proctor test (ASTM D698) prior to the
placement of the Leveling Pad material.
Leveling Pad Placement
A. The Leveling Pad shall be placed as shown on the construction drawings. Leveling Pad
steps shall not exceed 18 inches.
B. Place the stone leveling pad in uniform loose lifts a maximum of 6"
thick. Use appropriate methods to compact material to a minimum of 90 percent
of the relative density in accordance with (ASTM D4253) or as directed by the Engineer.
Prepare and smooth the leveling pad material to ensure complete contact of the first
course with the base.
C. The Leveling Pad shall be a minimum of 12—inches thick and extend 6—inches in front of
the bottom block and 12—inches behind the bottom block.
Free Draining and Structure Backfill Placement
A. Where required, place Structure Backfill (Class 1) in accordance with CDOT
Standard Specification Section 206.
B. Where required, place crushed rock backfill in uniform loose lifts a maximum of
6—inches thick. Consolidate the backfill with a minimum of three passes with a
24—inch wide walk—behind, vibrating plate compactor capable of delivering at
least 2000 pounds of centrifugal force. Compact to a density of at least 90
percent relative density of the backfill in accordance with ASTM D-4253 and
D-4254. In place density of the crushed rock backfill shall be confirmed using
ASTM D-6938.
C. Backfill containing frost or frozen lumps shall not be used. Backfill that has
been placed and becomes frozen shall be removed and replaced at the
Contractor's expense.
D. The Contractor shall provide immediate temporary storm water protection and wind erosion
control at the end of each day during construction. If settlement occurs as the result of
loss of backfill due to wind or water erosion, non—conforming backfill such as frozen fill or
over—saturated fill, or if the backfill does not meet compaction requirements, the
Contractor shall remove the backfill, and bring the elevation to the finished grade at the
Contractor's expense.
E. A final inspection will be made 30 days after the completion of the wall. Before final
project acceptance, the Contractor shall repair any backfill losses due to wind and water
erosion.
F. To avoid the foundation of the leveling pad being washed out by rain, the area in front of
the wall and around the leveling pad shall be backfilled as soon as practicable.
Unit Installation
A. Place the first course of units directly on the Leveling Pad with the aesthetic surface
facing out and the front edges tight together. Check units for level and alignment.
Adjacent units should be in contact. If possible, begin placing units at the lowest section
of the wall. Ensure that units are in full contact with the Leveling Pad.
B. The backfill in front and back of entire base row shall be placed and compacted to firmly
lock them in place. Check all units again for level and alignment. All excess material shall
be swept from top of units.
C. Install next course of wall units on top of base row. Follow the Manufacture's
recommendations to achieve a maximum batter of 1—degree. Position blocks to be offset
from seams of blocks below. Blocks shall be placed fully forward so knob and groove are
engaged. Check each block for proper alignment and Backfill to 12 inch width behind block
with Free Draining Backfill. Spread Class 1 backfill in uniform lifts not exceeding 6 inches.
Employ methods using lightweight compaction equipment that will not disrupt the stability
or batter of the wall. Hand—operated plate compaction equipment shall be used around
the block and within 3 feet of the wall to achieve consolidation. Compact backfill to 95%
of standard proctor (ASTM D 698, AASHTO T-99) density within 2% of its optimum
moisture content.
D. Install each subsequent course in like manner. Repeat procedure to the extent of
wall height.

and in front of the large block walls that is independent of the wall drainage system.
B. The CONTRACTOR shall be responsible for the condition and maintenance of any pipe or
conduit used to control surface water during construction. Upon substantial completion of
the work, surface water control pipes or conduits shall be removed from the site.
Alternatively, pipes or conduits may be left in place with the approval of the ENGINEER, but
shall be fully grouted (abandoned) or left in a manner that protects that structure and
adjacent facilities from ground loss associated with migration of fines through the pipe or
conduit. All work shall be subject to review by the ENGINEER.
C. Final grade above and below the retaining wall shall provide for positive drainage and prevent
ponding. Protect completed wall from other construction. Do not operate large equipment or

Method of Measurement
Concrete block gravity retaining walls will be measured by the actual number of square
feet of facial area installed and accepted. Facial area shall be defined as the area on a
vertical plane from the top of the leveling pad to the top of the wall cap at the wall
front face.
Basis of Payment
The accepted quantities will be paid for at the contract unit price per unit of
measurement for the pay items listed below:
Pay Item Pay Unit
Concrete Block Gravity Wall, Wet Cast Square Foot
All work and materials necessary and incidental to the construction of the
Concrete Block Gravity Wall, Wet Cast, including but not limited to block units,
drainage system, and geotextiles, structure backfill (class 1), free draining backfill
and leveling pad (crushed rock), temporary shoring (if necessary), and excavation
will not be measured and paid for separately, but shall be included in the work.
Block Facing Payment Reductions. In this subsection, "block" refers to either a
concrete gravity block or a precast cap unit.
A. A dislocated block is where the edge of an individual block is offset outward
more than 1/4 inch or placed with a vertical joint more than 1/4 inch from
the edge of adjacent blocks.
B. A cracked block is an individual block with any visible crack visible in natural
light from a distance equal to the wall height.
C. A corner knock—off is a block with any missing facial corners or any side
longer than % inch at the corner.
D. Substandard blocks are concrete blocks installed in any wall segments that
do not meet the certified values of compression strength, water absorption
rate, and freeze/thaw cycles. Substandard blocks include blocks actually in
the wall for which the Contractor does not provide reports and certifications
as required.
In the completed wall, or completed portion of the wall, if the number of defective
blocks (cracked blocks, corner knock—off blocks, dislocated blocks, efflorescence or
cement blemished blocks and substandard blocks) and blocks failing the straightedge
test exceeds 3 percent of the total number of blocks in any wall segment of 40 foot
horizontal or arc length, a price reduction will be applied to that portion of the wall.
The price reduction shall be 3 percent for each percent of defective blocks in this
portion of the wall exceeding 3 percent. This percentage shall accumulate thereafter to
a maximum reduction of 21 percent. For blocks subject to price reduction, if the
defects are repairable or the overall quality of wall can be improved, with the consent
from the Engineer, the Contractor may repair and reduce the percentage of price
reduction. A walkthrough inspection will be made as requested by the Contractor before
final payment.

PLANNING & ZONING COMMISSION MEMORANDUM
To: Planning and Zoning Commission
From: Matt Pielsticker, AICP, Planning Director
Date: October 15, 2015
Agenda Topic: Comprehensive Plan Update
Summary
PZC and planning staff reviewed and agreed to an approach to updating the Comprehensive
Plan earlier this summer. Updating the Comprehensive Plan was again re -affirmed as a top
priority of the Avon Town Council with approval of the 2016-17 Strategic Plan on October 13,
2015. Updating the Comprehensive Plan is listed as a Tier 1 priority in the 2016-17 Strategic
Plan. Staff has worked through an initial redline/strikethrough of 2006 Comprehensive Plan.
The redline/strikethrough effort was focused on clean-up, removing redundancies,
reorganization, removal of elements that have been completed (i.e. "develop a detailed plan for
west town center'', or "develop a place for cultural events such as an open air pavilion') and in
many cases replacing obligatory "shall" language with suggestive. While reviewing the 2006
Comprehensive Plan planning staff found several major areas where policy direction would be
helpful and those areas are outlined below. First, a reminder of the overarching goals of this
update process.
Goals of Plan Update
Consolidate the Town's various Comprehensive Plan documents.
The 2006 Comprehensive Plan will serve as the leading document for amendment and
incorporation of other plan elements:
o West Town Center Implementation Plan (2007)
o East Town Center District Plan (2008).
o Transportation Plan (2009).
o Nottingham Park Plan (2009), and
o Recreational Trails Master Plan (2009).
Incorporation of new plan elements, or major modifications to existing elements:
o Multi -Modal Parking & Transportation - new
o Climate Adaptation & Disaster Preparedness/Resiliency - new
o Housing - major update
o Economic Development - major update
One final compiled document that is easier to amend in the future.
• Provide indicators matrix to monitor implementation progress after adoption.
PZC Direction
At your October 20, 2015 meeting, staff is seeking direction from PZC on the following items
prior to finalizing a version for review:
Planning Districts. The plan divides the Town into 28 individual planning districts
and provides the policy direction to develop a detailed district master plan for each
PAGE1OFz
A
Avon
COLORADO
district, or alternatively, where no district plan is developed to consider flexible PUD
zoning in place of straight zoning. Since adoption, there were three detailed plans
produced - West and East Town Center, and Nottingham Park. As we work towards
incorporating these standalone district plans into the Comprehensive Plan, it has
become apparent that a major consolidation of the planning districts is warranted, as
well as revisiting the district plans and pairing down the contents. Lastly, the Town
continues to move away from PUD districts and that policy direction will be stricken.
2. Housing. Confirm that a major update is necessary. Eagle County is currently
updating their Housing Needs Assessment, last updated in 2012, and Staff believes
the information that comes out of this update will be timely and offer policy language
for this section.
3. Eagle County Land Use Map. The plan defers to the Eagle County Land Use Map for
areas adjacent to the Town such as Eagle Vail. Should the Town produce its own
future land use map for these areas?
4. Consultant Services. Staff has determined that the functions of a Long Range Planner
full-time position could be supplemented with consultant services. In the 2016
proposed budget, staff is proposing $61,000 for consultant services for the following
elements of the plan update:
a. Multi -modal Parking & Transportation
b. Climate Adaptation & Disaster Preparedness
c. Graphic representations and amendments - Eagle County and/or third party
cartographer
d. GIS services
e. Publishing
Staff welcomes comments or additional suggestions from PZC on the above
elements.
Next Steps
• Staff will bring redline/strikethrough to PZC for a work session and further
discussion in November.
• Obtain publisher to combine pertinent elements of all Comprehensive Plans into one
document for further editing and complete picture of scope of this work effort.
• Other consultant services for specific plan elements would be obtained after the
start of 2016.
