ADJOURN TO: Planning and Zoning Commission FROM: David McWilliams, AICP, Town Planner RE: SUB20004 Major Subdivision (Preliminary) Lot 5D Riverfront Subdivision / 330 Riverfront Lane PUBLIC HEARING DATE: August 26, 2020 STAFF REPORT OVERVIEW: This Staff report contains one application for consideration by the Planning and Zoning Commission (PZC): Major Subdivision for six (6) new duplex lots and four (4) common element tracts in the Riverfront Subdivision: Lots 8,9 and 16-19 and Tracts 5E-5H. The PZC will make a recommendation on the application to the Town Council for final action on the preliminary plan. All Major Subdivision Plans require preliminary and final approval. Action by Town Council for the Preliminary Subdivision is scheduled for September 22, with the Final Subdivision hearing dates pending. SUMMARY OF REQUEST: Jim Telling (the Applicant) with East West Resort Development presets the plat for units under construction. REVIEW PROCESS: This application follows the general preview procedures set forth in Code Section 7.16.020, General Procedures and Requirements. Detailed review procedures are in Table 7.16-1 and in 7.16.070. Both mailed and published notice were provided for the public hearings. PZC will review the Application and conduct a public hearing on September 1, 2020. After reviewing the Application materials, Staff analysis, and considering public input, the PZC will make a recommendation to Town Council. The final action is by Resolution of the Town Council after conducting an additional public hearing, tentatively scheduled for September 22, 2020. PUBLIC NOTICE: Notice of the public hearing was published in the August 21, 2020 edition of the Vail Daily in accordance with Sec. 7.16.020(d) of the Avon Development Code (ADC) and noticed for multiple meeting dates. Mailed notice was sent by staff on August 19. PROPERTY DESCRIPTION: Lot 5D was platted in its current form from the first resubdivision of dwelling units to the west. Now, the dwelling units between the western ones and the lodge building are proposed for subdivision. The tracts delineate Waterfront Way, the one way access, and common properties to be controlled by the HOA. The anvil shaped parcel is the subject of this application. SUBDIVISION PLAN - REVIEW CRITERIA 7.16.070(e) Preliminary Plan Review Criteria. The PZC will use the following review criteria as the basis for recommendations on applications for preliminary plan subdivision applications: (1) The proposed subdivision shall comply with all applicable use, density, development and design standards set forth in this Development Code that have not otherwise been modified or waived pursuant to this Chapter and that would affect or influence the layout of lots, blocks and streets. Applicants shall not create lots or patterns of lots in the subdivision that will make compliance with such development and design standards difficult or infeasible; Staff Response: The proposed lots coincide with individual dwelling units to be sold. The final designs were approved as two (2) different phases by Town Council in 2018 and 2019. The proposal complies with all applicable standards attached to this property. (2) The subdivision application shall comply with the purposes of this Development Code; Staff Response: The application complies with the purposes of the Development Code (Avon Development Code section 7.04.030), including: (a) Divide the Town into zones, restricting and requiring therein the location, erection, construction, reconstruction, alteration and use of buildings, structures and land for trade, industry, residence and other specified uses; regulate the intensity of the use of lot areas; regulate and determine the area of open spaces surrounding such buildings; establish building lines and locations of buildings designed for specified industrial, commercial, residential and other uses within such areas; establish standards to which buildings or structures shall conform; establish standards for use of areas adjoining such buildings or structures; (g) Prevent the inefficient use of land; avoid increased demands on public services and facilities which exceed capacity or degrade the level of service for existing residents; provide for phased development of government services and facilities which maximizes efficiency and optimizes costs to taxpayers and users; and 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. (3) The subdivision application shall be consistent with the Avon Comprehensive Plan and other community planning documents; Staff Response: The subdivision application is in District 2: The Riverfront District of the Comprehensive Plan. The area description speaks of providing access to its key components, including the River and Eagle Valley Trail. The Planning Principles do not address this subdivision application. Staff finds no conflicts with the Comprehensive Plan or subarea plans. (4) The land shall be physically suitable for the proposed development or subdivision; Staff Response: Buildings are currently being constructed on the lands in a scale and design that is compliant with all applicable criteria. The land is physically suited for the subdivision. (5) The proposed subdivision shall be compatible with surrounding land uses; Staff Response: The proposed subdivision is surrounded by townhome style dwelling units and a lodge building under construction. The uses are compatible. (6) There are adequate public facilities for potable water supply, sewage disposal, solid waste disposal, electrical supply, fire protection and roads and will be conveniently located in relation to schools, police, fire protection and emergency medical services; Staff Response: All public utilities have been fully vetted in this PUD. (7) The proposed utility and road extensions are consistent with the utility's service plan and are consistent with the Avon Comprehensive Plan and Comprehensive Transportation Master Plan; Staff Response: Proposed extensions were vetted during the design and construction phase of these projects. (8) The utility lines are sized to serve the ultimate population of the service area to avoid future land disruption to upgrade under-sized lines; Staff Response: Utility lines were properly sized for the type of construction. (9) The subdivision is compatible with the character of existing land uses in the area and shall not adversely affect the future development of the surrounding area; Staff Response: The subdivision includes for sale duplex units and common element tracts which achieve an orderly and compatible character with the surrounding land uses. (10) A proposed subdivision for an existing PUD shall be consistent with the relevant PUD Master Plan as reflected in the approval of that PUD; Staff Response: The Riverfront PUD Master Plan was modified in 2017, and design approval given in 2018 and 2019 for the land use typology that this subdivision achieves. (11) Appropriate utilities, including water, sewer, electric, gas and telephone utilities, shall provide a "conditional capacity to serve" letter for the proposed subdivision; Staff Response: Capacity letters were received during development review. Final acceptance will be required accordingly. (12) That the general layout of lots, roads, driveways, utilities, drainage facilities and other services within the proposed subdivision shall be designed in a way that minimizes the amount of land disturbance, minimize inefficiencies in the development of services, maximizes the amount of open space in the development, preserves existing trees/vegetation and riparian areas, protects critical wildlife habitat and otherwise accomplishes the purposes of this Development Code; Staff Response: The lot layout was vetted in the design review process. There are no changes to approved setbacks or open space allocations with this application. (13) Evidence that provision has been made for a public sewage disposal system or, if other methods of sewage disposal are proposed, adequate evidence that such system shall comply with state and local laws and regulations; Staff Response: Provision of sewage was vetted in the Development Plan application phases for these units. (14) Evidence that all areas of the proposed subdivision that may involve soil or topographical conditions presenting hazards or requiring special precautions have been identified by the applicant and that the proposed use of these areas are compatible with such conditions or that adequate mitigation is proposed; Staff Response: To Staff’s knowledge, no development took place in a hazardous part of the site. This area slopes steeply to the Eagle River and has been studied extensively for its feasibility in holding buildings. Soils and geotechnical reports were reviewed during the building permit process. (15) The subdivision application addresses the responsibility for maintaining all roads, open spaces and other public and common facilities in the subdivision and that the Town can afford any proposed responsibilities to be assumed by the Town; Staff Response: The Town has no overt responsibilities relating to the maintenance and operations of this subdivision. Common facilities are addressed with this subdivision. (16) If applicable, the declarations and owners' association are established in accordance with the law and are structured to provide adequate assurance that any site design standards required by this Development Code or conditions of approval for the proposed subdivision will be maintained or performed in a manner which is enforceable by the Town; and Staff Response: In addition to a pre-existing master declaration for the Riverfront Subdivision, these Townhomes will be subject to their own set of requirements created by a new set of declarations and owners’ association recorded with this subdivision. There will be no obligations assigned to the Town. (17) As applicable, the proposed phasing for development of the subdivision is rational in terms of available infrastructure capacity and financing. Staff Response: The proposed subdivision already hosts buildings which are nearing completion. This subdivision includes builds from Phase I and III of a multi-phase project. AVAILABLE ACTIONS: • Continue the Public Hearing pending additional information • Approve a Record of Decision recommending Town Council approve the preliminary subdivision • Approve a Record of Decision recommending Town Council deny the preliminary subdivision STAFF RECOMMENDATION FOR MAJOR SUBDIVISION PLAN: Approval of the Record of Decision with the following findings: Findings: 1.

Final Plat Riverfront Townhomes Phase II Thank you, David McWilliams 970-749-4023 / cmcwilliams@avon.org Attachment A Attachment A Attachment A TO: Planning and Zoning Commission FROM: David McWilliams, AICP, Town Planner RE: Conditions of Approval - MJR20005 Lots 6 and 7 Riverfront Subdivision / 358 and 368 Riverfront Lane DATE: August 26, 2020 STAFF REPORT OVERVIEW: This Staff report contains required materials to achieve the Conditions of Approval from case MJR20005 as described in the Town Council and PZC records of decision. The application for two duplex structures was approved in summer 2020 with unfinished items for PZC review. Now, Jim Telling (the Applicant) presents a plan required to respond to the following items: • realigning the Eagle Valley Trail, particularly the corner of duplex number 4 • use of “Redi Rock” retaining walls • strategic placement of the felled cottonwood trees will be presented The Applicant produced a wetland report that verifies compliance with applicable regulations for the siting of the buildings, landscape features, and the relocated Eagle Valley Trail (the Trail). Additional items for review include: • The Garden Level entrances and stepping stone paths have been removed from Residences 3+4. These were added for Town Council review. • The boulder walls at the west side of Residence 4 have been changed to Redi-Rock walls. These are intended to match the existing walls along the path switchback. • Additional drought tolerant native landscaping has been added to the interior of the path switchback per the direction from ERWSD. This area will receive only above grade temporary irrigation. • Boulder wall configuration has changed on the east side of Residence 3 • Additional boulder wall has been added on the west side of Residence 2. • Rain garden location and grading have been updated on the south side of the Duplex 1-2. • Minor adjustments to the plant layout and species along the west side of Residence 4. • Addition of concrete aprons at the garage doors of all four units. • Trail has been shifted by 5’-0” to the south at Residence 4. These Condition of Approval items are not subject to a public hearing, but their satisfactory completion is required. While this is not a public hearing, Staff encourages PZC to consider any public comment on the matter. PROPERTY DESCRIPTION: Lots 6 and 7 are .45 and .2 acres, respectively. The lots are currently in the grading permit process with Staff based upon the development approval from case MJR20005. PLANNING ANALYSIS: Lot Coverage, Setback and Easements: Lots 6 and 7 both have the following building envelope and easements: Front Side Eagle River (Back) 10' O' 75' (or property line, whoever is more restrictive) Both duplexes have elements that protrude over the rear setback. Per the PUD Design Standards, the property is permitted, "limited minor encroachments as allowed in the development plan" in the river setback. PZC and Town Council both discussed the protrusions in depth and approved them as proposed. The Applicant modified the Duplex 1-2 size and the Duplex 3-4 angle for Town Council review in response to PZC comments. Now, the Applicant proposes a further amendment of the Trail and additional landscaping between Residence 4 and the Trail. Staff finds that these changes achieve a more appropriate overall aesthetic. One missing element on the plan is the use of removed trees to limit access to the river. Staff met with the contractor on site to ensure that the recycling of trees will be part of the grading permit process. DESIGN STANDARDS ANALYSIS: Landscaping & Irrigation: The total landscape area proposed is 13,824 square feet combined. 276 landscape units are required, and 741 units are proposed, primarily of spruce, pine, aspen, several deciduous shrub species, grasses, ground cover, and mulch areas. Notable changes include the area above the path on Lot 7 that has landscaping, and the additional landscaping on Tract H. Tract H will not be permanently irrigated due to Eagle River Water and Sanitation District policy. The applicant has not proposed an irrigation plan, and hydrozones are not expressly demarcated. A satisfactory irrigation plan must be presented to Staff before a building permit is issued. The plan does approximate an irrigated area (to be determined with the full plan) of 8.9% and 15.6% of the landscape area for Lots 6 and 7, respectively. Of note is that drip irrigation is encouraged in ADC and counted as 3 square feet per head. The wetlands study demonstrates no concerns for the eastern boulder wall or realigned Trail. The wetlands below the cul-de-sac are proposed to be preserved. The realigned boulder wall on Lot 6 preserves existing trees and creates a more natural buffer between the Trail and the development. The application still removes native landscaping within the building envelope as well as within the 75’ river setback, and the PUD Development Plan states, “the 75-foot river setback will be largely left in its natural state.” Retaining Walls: All retaining walls are proposed as boulder materials, except for the Redi-Rock walls on the western side of unit 4, as required in the Conditions of Approval. This wall was chosen to match the adjacent walls installed as part of the path project. All walls are between four (4') and two (2') feet tall. Snow Storage: The changes to the snow storage plan are proposed in this plan are negligible. DEVELOPMENT PLAN & DESIGN REVIEW - REVIEW CRITERIA § 7.16.0SO(f), Development Plan 1. Evidence of substantial compliance with the purpose of the Development Code as specified in §7.04.030, Purposes; 2. Evidence of substantial compliance with §7.16.090, Design Review; 3. Consistency with the Avon Comprehensive Plan; 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; 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 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: Staff finds that these modifications address the applicable review criteria and achieve them better than the original application. These modifications comply with the Riverfront PUD design guidelines. Adherence to the Conditions of Approval creates a more appropriate design. §7.16.090(1), DESIGN REVIEW CRITERIA 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; 2. The design meets the development and design standards established in this Development Code; and 3. The design reflects the long- range goals and design criteria from the Avon Comprehensive Plan and other applicable, adopted plan documents. Staff Response: The modifications are compliant with these Design Review Criteria. AVAILABLE ACTIONS: • Accept the modifications as proposed • Require additional information or additional modifications STAFF RECOMMENDATION: Approval of the modifications as proposed. MOTION TO RECOMMEND APPROVE THE CONDITIONS OF APPROVAL: “I move to approve the Conditions of Approval for case MJR20005 for landscaping considerations on Lots 6 and 7, Riverfront Subdivision.” ATTACHMENTS (a) Landscape Plan (b) Wetlands Report Thank you, David McWilliams 970-749-4023 / cmcwilliams@avon.org © 2020 Zehren and Associates, Inc. east west partners 08.24.2020The Residences at Riverfront 2 56 PLANT LEGEND: EVERGREEN TREES DECIDUOUS TREES SHRUBS PERENNIALS MIXED SPECIES (1 GAL) 294 SF NATIVE SEED MIX (GRASS / WILDFLOWERS) GROUND COVER ORNAMENTAL GRASSES BLUE SPRUCE (14' HT) QTY - 7 Picea pungens 'Fastigiata' WEEPING WHITE SPRUCE (12' HT) QTY - 2 Picea glauca 'Pendula' BRISTLECONE PINE (10' HT) QTY - 2 Pinus aristata MULTI-STEM ASPEN (3" CAL / 14' HT) QTY - 10 Populus tremuloides ROCKY MTN GLOW MAPLE (3" CAL) QTY - 4 Acer grandidentatum MUGO PINE (6' HT) QTY - 17 Pinus mugo var. rostrata WOODS ROSE (15 GAL) QTY - 17 Rosa woodsii MORDEN GOLDEN GLOW ELDERBERRY (15 GAL) QTY - 13 Sambucus racemosa 'Morden Golden Glow' RED TWIG DOGWOOD (15 GAL) QTY - 24 Cornus sericea 'Baileyi' TIGER EYES SUMAC (15 GAL) QTY - 15 Rhus typhina 'bailtiger' COMMON LILAC (14' HT) QTY - 9 Syringa vulgaris 'Andeken an Ludwig Spaeth' FRAGRANT SUMAC (15 GAL) QTY - 29 Rhus aromatica HARRISON'S YELLOW ROSE (15 GAL) QTY - 25 Rosa x harisonii 'Harrisons Yellow' GAMBEL OAK (15 GAL) QTY - 30 Quercus gambellii SERVICEBERRY (15 GAL) QTY - 24 Amelanchier alnifoila BLUE MUFFIN VIBURNUM (15 GAL) QTY - 12 Viburnum dentatum 'Blue Muffin' GOOSEBERRY (15 GAL) QTY - 20 Ribes aureum ORANGE ROCKET BARBERRY (15 GAL) QTY - 9 Berberis thunbergii 'Orange Rocket' DIABOLO NINEBARK (15 GAL) QTY - 12 Physocarpus opulifolius 'Diabolo' MONTGOMERY SPRUCE (3' HT) QTY - 2 Picea pungens 'Montgomery' COMMON JUNIPER QTY - 25 Juniperus communis var. depressa CRUSADER COCKSPUR HAWTHORN QTY - 2 (3" CAL) Crataegus crus-gali inermis "Crusader' NANKING CHERRY (6' HT / Multi-stem) QTY - 3 Prunus tomentosa LANDSCAPE UNIT QTY (TREES) 16 16 102 70 28 14 12 17 LANDSCAPE UNIT QTY (Shrubs) TOTAL LU FOR TREES = 334 (45%) TOTAL LU FOR SHRUBS = 308 (42%) 13 24 15 25 9 29 25 30 24 12 20 9 12 2 LANDSCAPE UNIT QTY FEATHER REED GRASS (15 GAL) QTY - 89 Calamagrostis acutiflora 'Karl Forester' RUSSIAN SAGE QTY - 42 Perovskia atriplicifolia 42 BLUE AVENA GRASS (5 GAL) QTY - 9 Helictotrichon sempervirens 9 89 1 TOTAL LU GRASSES / PERENNIALS = 99 (13%) ROCKY MTN.

Box 1976 Avon, CO 81620 RE: Wetlands Evaluation Riverfront Lots 6 & 7 – Avon, CO Dear Jesse, Per your request we visited Lots 6 & 7 of the Riverfront at Avon project area to update the wetland map, which has expired, and determine whether the proposed project would impact wetlands. An aerial overview of the project site is provided in Photo 1. METHODS Field reconnaissance was completed on June 29 and July 9, 15 and 31, 2020. The wetlands evaluation was conducted in accordance with the U.S. Army Corps of Engineers Wetland Delineation Manual (1987) and the Regional Supplement for the Western Mountains, Valleys and Coast (2010). The limit of wetlands was evaluated using the vegetation, soils, and hydrology criteria of the manuals, and is consistent with the methodology used for a formal U.S. Army Corps of Engineers wetland delineation. The boundary determination was completed by Heather Houston of Birch Ecology and Dave Buscher, a certified professional soil scientist with Buscher Soil & Environmental. The study area extended from the project site to the stormwater drainage that borders the eastern side and the northern edge of the Eagle River Wetland south of the Eagle Valley Trail (Figure 1). ENVIRONMENTAL SETTING The project site is on a steep south-facing slope just north of the Eagle River (Photo 2). Riverfront Lane provides access and is adjacent to the parcel at the top of the slope. The existing Eagle Valley Trail, a paved recreational path, is located at the southern edge of the study area near the Photo 1. Aerial Overview of the Project Site. Attachment B Eagle River (Photo 3). There are a few social trails that cut through the parcel, down the steep hillside to connect Riverfront Lane to the Eagle Valley Trail. West of these social trails, a stand of aspen (Populus tremuloides) and narrowleaf cottonwood (Poplulus angustifolia) trees grows with dense understory of serviceberry (Amelanchier alnifolia) and chokecherry (Prunus virginiana var. melanocarpa) shrubs and Canada thistle (Cirsium arvense), a noxious weed (Photo 4). The central part of the property has been seeded with upland grasses including smooth brome (Bromus inermis) and crested wheatgrass (Agropyron cristatum) (Photo 2). A few scattered weeds occur in this area such as ox eye daisy (Leucanthemum vulgare), white top (Cardaria draba), and musk thistle (Carduus nutans ssp. macrolepis), all state-listed noxious weeds. The eastern part of the property is bordered by a drainage swale that emerges from a culvert in the large, curved retaining wall and connects to another culvert below the Eagle Valley Trail, which drains into the Eagle River (Photo 5). This area has an overstory of narrowleaf cottonwood trees growing with a dense understory of willow hawthorn (Crataegus saligna), dogwood (Cornus sericea), and Woods’ rose (Rosa woodsii), with Canada thistle in the shaded understory (Photo 6). The Eagle River Wetland lines the bank of the Eagle River south of the project area (Photos 8 & 9). The riparian overstory includes a dense cover of sandbar willows (Salix exigua) along the ordinary high water line, with shrubs including river birch (Betula occidentalis), dogwood (Cornus sericea), and willow hawthorn and an overstory of mature narrowleaf cottonwood trees. In the wetland understory, areas of variegated horsetail (Equisetum variegatum), Baltic rush (Juncus balticus), and creeping spikerush (Eleocharis palustris) grow in the sandy soil, with native forbs including shooting star (Dodecatheon pulchellum), and northern green orchid (Platanthera aquilonis). RESULTS The results of the field investigation are summarized in the attached Figure 1. We did not identify any vegetated wetlands within the Lot 6 project area; however the “bed and bank” drainage channel that connects the culvert outfall at the retaining wall to the culvert below the bike path, which drains to the Eagle River, is a regulatory drainage (Photo 7). Soil Pit 1 was used to confirm that no regulatory wetlands occurred adjacent to this bed-and-bank drainage channel. The soil in this location was not hydric and lacked indicators of a wetland hydrology (Photo 10). The Eagle River Wetland is located south of the project area. As shown by Figure 1, a slight realignment of the Eagle Valley Trail is proposed near the condominium buildings. This shift would primarily disturb an unvegetated strip next to the asphalt path, and a sliver of upland habitat between the trail and the Eagle River Wetland (Photo 11). The delineated boun dary of the Eagle River Wetland is more than 50 feet away and would not be disturbed by the proposed trail relocation. Attachment B SUMMARY The proposed Townhome buildings would not impact jurisdictional wetlands or other Waters of the U.S. since the limits of disturbance are outside the area of the drainage swale. Moreover, the proposed changes to the Eagle Valley Trail will not disturb the Eagle River Wetland. It is our assumption that the two pipe discharges to be located south of the bike path could be designed to avoid wetland impacts, and therefore would not require a wetland permit from the U.S. Army Corps of Engineers. Please call if you hav e questions. Sincerely, Heather Houston President & Senior Ecologist Attachment B Photo 2.

Now, Melissa Marts (the Applicant) presents a modified plan. The applications were approved in Winter 2020 with relevant landscaping and building materials conditions as follows: (1) Screening alternatives, color schemes, and architectural elements will be brought before PZC to alleviate south and west elevations prior to completion of the project. (2) A new landscape plan must be approved by PZC and installed prior to completion of the project. The former barn area shall be planted with appropriate riverine trees to replace, at a 1:1 value or better, any trees removed and not replanted on the adjacent property (Lot 9 Block 3 Benchmark at Beaver Creek) and to properly screen the Eagle Valley Trail; (3) The fence design will be presented to planning Staff for approval before its construction; and (4) All lighting on the property shall comply with Avon’s Dark Sky Ordinance before a final Certificate of Occupancy will be issued. These items are not subject to a public hearing, but their satisfactory completion in front of PZC is required. Staff encourages allowing public comment, if applicable. PROPERTY DESCRIPTION: The joint applications approved a necessary expansion of the wastewater treatment facility. The site is 100% disturbed with a combination of below and above ground structures, surface parking, and storage areas. The property is undergoing grading and the beginnings of the construction phase. ANALYSIS: Landscaping & Irrigation: A new landscape plan is not included in this modification. The successful presentation of this element is required to be presented to PZC before the Building Certificate of Occupancy will be issued. Building Design, Building Materials and Colors: All of the buildings are proposed to be painted three colors: two grays and a brown color. 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. The applicant modified exterior detailing to include metal coping (blue), vertical seam metal and alternating coloring. These features serve to break up the large monotonous expanse. Per code, buildings are required to have four-sided design and break up linear aspects. The modifications achieve the Condition of Approval for the south and west elevations. Roof Material and Pitch: The modified proposal does not include roof materials. A consistent of color is presented in this modification, satisfying the Condition of Approval for architectural elements. Screening: The proposal includes three (3) tall Strobic Fans which propel odorous air into the sky. From Nottingham Park, they will be the most visually impactful elements of the design. While the ADC screening section speaks to fully screened mechanical equipment, it leaves an alternate screening provision: “Mechanical equipment that is not screened in full compliance with the screening standards of this Section shall be reviewed in accordance with Section 7.16.090, Design Review. Alternate screening methods may include, but shall not be limited to, increased setbacks, increased landscaping, grouping the equipment on specific portions of a site, architectural features and painting.” The fan stacks are proposed to be painted a dark brown, the darkest color available from the palette. Staff finds the color change acceptable to the scale of the project. If the fans were fully enclosed, the bulk would be unsightly. Exterior Lighting: All exterior lighting is required to be compliant with the Dark Sky requirements before the Building Certificate of Occupancy will be issued. REVIEW CRITERIA 7.16.150(d) Location, Character & Extent Review Criteria 1) Evidence of substantial compliance with the purpose of this Development Code; 2) Consistency with the Avon Comprehensive Plan; 3) Physical suitability of the land for the public way, place, structure, facility or utility; 4) Compatibility with surrounding land uses; and 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: The proposed modifications create a more visually appealing project in the heart of Avon and relate to the use to the location. A landscape plan is still required to be brought to PZC before the project ends. Staff finds that the modifications comply with the applicable Review Criteria. AVAILABLE ACTIONS: • Accept the modifications as proposed • Require additional information or additional modifications before a building permit will be issued STAFF RECOMMENDATION: Approval of the modifications as proposed, with the condition that the landscaping element will be brought to PZC at a later date. MOTION TO APPROVE THE MODIFICATIONS: “I move to approve the Conditions of Approval for cases LCE20001 and TEN19001 for building modifications on Tract N, Block 3 Benchmark at Beaver Creek Subdivision, with the condition that the landscaping element be brought to PZC at a later date and other conditions be addressed before a final Certificate of Occupancy is issued.” ATTACHMENTS A.

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). Figures 21 and 22 show AWWTF from the sidewalk near Beaver Creek Landing. The most noticeable differences between the existing facility and the future facility include: New buildings housing the new aeration basin volumes and secondary clarifier Relocated fence line on the left that has been moved to match the property line Cohesive paint scheme Odor control equipment o Strobic fans on the roof of the new aeration basin o Carbon scrubber system to the south side of the facility Figure 21: Current Avon WWTF from Beaver Creek Landing.

Figures 23 and 24 show the existing and proposed facility from the walking path around Nottingham Lake. From this angle, the new building over the existing and new aeration basins are visible. The new HVAC equipment, ductwork, and Strobic fans can also be seen. All new equipment on the roof will be colored to match the new paint scheme for the facility. All new exterior lighting will be Dark Sky compliant full-cutoff fixtures. Figure 23 Current Avon WWTF from Nottingham Lake. Attachment AAttachment B Avon WWTF 1041 Permit Application December 6, 2019 Page 52 Figure 24: Proposed Avon WWTF from Nottingham Lake 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. Manylarge projects in Vail and Avon have had cranes in recent years and this will be a similar piece of Attachment AAttachment B 1234567 AA 05A06 7422.89 T.O. DT A 05A07 F 05A08 G 05A08 7424.72 T.O.
