CODE OF CONDUCT FOR CITIZEN COMMENTS DURING CITY OF ASPEN PLANNING AND ZONING COMMISSION MEETINGS: Planning and Zoning Commission meetings shall be conducted in a fair and impartial manner. Citizen comments shall respect the need for civility for effective public discussion of issues. Citizen comments regarding any matter not on the agenda will be allowed during the designated time on the agenda and may be disallowed at other times during the meeting. Those wishing to address the Commission on any matter not on the agenda will be allowed a three-minute presentation per speaker. This “three minute rule” shall also be applicable to citizens wishing to address the Commission during the public comment portion of public hearings for agenda items. The Chair or presiding officer retains the discretion to allow or disallow public comment on any agenda item that is not designated as a public hearing. All citizen comments should be directed to the Commission, and not to individual members of the public. 2 3 Defamatory or abusive remarks, shouting, threats of violence or profanity are OUT OF ORDER and will not be tolerated. Persons violating these policies may be asked to terminate their comments. In the event of repeated violations or refusal to abide by these policies or directives, the Chair or presiding officer has authority to request the individual to leave the meeting or direct a peace officer to remove the individual from the Commission meeting. Revised July 8th, 2019 3 Aspen Planning and Zoning Commission July 2, 2019 Chairperson McKnight called the meeting to order at 4:29 PM. Commissioners in attendance: Spencer McKnight, Teraissa McGovern, Jimmy Marcus, Don Love, Ruth Carver, Brittanie Rockhill Absent: Rally Dupps, Ryan Walterscheid, Scott Marcoux Staff present: Jeannine Stickle, Records Manager Andrea Bryan, Assistant City Attorney Jennifer Phelan, Deputy Planning Director STAFF COMMENTS None. COMMISSIONER COMMENTS None. PUBLIC COMMENTS None. APPROVAL OF MINUTES Ms. McGovern motioned to approve the minutes from June 4th, 2019. Mr. Love seconded. All in favor, motion carried. DECLARATION OF CONFLICT OF INTEREST None. PUBLIC HEARING None. OTHER BUSINESS Code of Conduct Ms. Bryan stated that it was brought to her attention at a recent meeting that Planning and Zoning would like to adopt a more formal decorum policy to serve as a guideline and notice to the public about what is expected as far as conduct during public meetings and public hearings. She drafted a resolution adopting a code of conduct regarding citizen comments during Aspen Planning and Zoning Commission meetings. It is intended to guide people as to the rules that pertain to matters not on the agenda as well as matters on the agenda and are public hearings versus matters that are on the agenda that are not public hearings. There is a sentence in the document that states that it is within the residing officer’s discretion to allow or disallow public comment during agenda items that are not public hearings. This is a combination of policies adopted by Aspen City Council, APCHA, and the Town of New Castle. She asked the commissioners if they had any questions. 4 Mr. McKnight stated that the policy looks great and will be beneficial to have. He asked the reason that the policy states that citizens’ comments should be directed to the commission and not to individual members of the public or applicant. Ms. Bryan stated that there are times when members of the public pose hypothetical questions that could be viewed as questions to the applicant or the board as a whole. That section is trying to alleviate personal attacks or comments directed to an individual. Ms. Phelan stated that there are general tricks that the Chair can bring into the hearing. If someone does give a statement and a question, the Chair could say something like “what I think I heard is a statement and a question. And the question we, as a board, can ask the applicant at the end.” That will help break up the comment and manage the meeting. Ms. Carver stated that she has only seen one issue of bad conduct in her time on Planning and Zoning and believes that Ms. McGovern handled it perfectly. She asked if it would be possible to extend citizens’ time at the discretion of the chair. She is concerned that three minutes is not enough time. Ms. Bryan stated that she sees three minutes as the general standard adopted by a lot of other boards and commissions. The general reason is that discussions do need to stay focused in order for the Commission to get their business done. That being said, it’s up to the Commission. There is discretion built into the rules. At a meeting with a full room, five minutes of public comment per person will make for a very long meeting. Mr. Love stated that he has seen a lot of communities where the rule is two minutes. Ms. Bryan stated that there will be people who will abuse it, and that’s why it’s important that the Commission have the policy be posted so that he public can access it. She proposed that it be included in the meeting packets. Mr. McKnight stated that three minutes is good. If people need to formulate their thoughts, the commission can take it as a case-by-case scenario. Ms. Carver stated that, if there is a crowd, the Commission should talk to them before they get started. Mr. McKnight stated that Ms. Phelan usually does a great job with that. Ms. Bryan stated that people will now know to expect three minutes going in. Ms. McGovern motioned to approve Resolution 9. Ms. Rockhill seconded. Commissioner vote. Resolution passed unanimously. ADJOURN Ms. Carver motioned to adjourn the meeting at 4:39 PM. Ms. McGovern seconded. All in favor, motion carried.

LOCATION: 480 Doolittle Drive CURRENT ZONING: Public (PUB) SUMMARY: The Applicant requests the P&Z (Planning and Zoning Commission) recommend approval to City Council to approve the development of a new water treatment facilities and upgrades to existing facilities at the Water Treatment Plant. STAFF RECOMMENDATION: Staff recommends the P&Z provide a recommendation of approval, with conditions. Aerial Image of Site Rendering of proposed vehicle maintenance and storage facility 6 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 2 of 14 LAND USE REQUESTS AND REVIEW PROCEDURES: The Applicant is requesting the Planning and Zoning Commission provide a recommendation on the following land use actions by City Council: • Major Public Project Review – (Chapter 26.500) for development proposed by a governmental entity. (See “Staff Evaluation” for full description of this review process). This is a two -step process, with the P&Z making recommendation to Council. Council has the final decision-making authority. • Planned Development – Project and Detailed; combined review – (Chapter 26.445) to establish the dimensional requirements and other essential elements of the project. • 8040 Greenline Review – (Chapter 26.435) – required of projects in the 8040 Greenline review area. • Growth Management, Essential Public Facilities Review – (Chapter 26.470) – to review the employee generation created by the facility and the request to waive mitigation requirements. The P&Z determines the employee generation. If it’s determined that employees are generated, the Commission makes a recommendation to City Council on the request to waive the affordable housing mitigation requirement. • Transportation and Parking Management, Special Review – (Chapter 26.515) – to review the provisions of parking and contributions to multi-modal access and circulation for an Essential Public Facility. • Conditional Use Review – (26.425.040) – to review the vehicle maintenance and storage facility which is listed as a conditional use in the Public (PUB) zone district. BACKGROUND: The project site is located on the Water Treatment Plant and Affordable Housing Project Specially Planned Area (SPA). In 1996 the property received approval for the affordable housing subdivision, and a Planned Development overlay that formally created twenty five lots. SPA and Planned Developments (PD) were similar overlays, allowing for dimensional variations; however, PD only allowed use variations but due to the similarities, SPA’s were rescinded and were renamed PD’s. Lots 1-24 contain affordable housing units, and lot 25 includes the Water Treatment facilities, including a reservoir, administration building, and other facilities that support the water treatment process. The property is zoned Public (PUB) with an PD overlay. According to the recorded Water Treatment Plant and Affordable Housing Project SPA and Subdivision Final Plat (Book 41, Page 41) from 1997, the lot is 49.705 acres (2,165,149.8 square feet). The subdivision and affordable housing approval established area and bulk requirements for the affordable housing project. Dimensional requirements for the Water Treatment Facility were established during the adoption of the SPA in 1984, pursuant to Book 15, Page 93 (shown in Figure 2). Subsequent amendments did not change the dimensional requirements of the Water Treatment Plant, with the execption of the lot area. The dimensional requirements were established as follows: Lot Area: 54.36 Acre acres (amended to 49.705 acres) Min. # of Off Street Parking Spaces: 11 Floor Area Ratio: 0.08:1 Min. Setback (All sides): 100 feet Max. Height: 25 feet Open Space (%): 91.54% 7 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 3 of 14 Proposal: Figure 1 – Plat, 1997, Book 41, Page 41. Lot 25 boundary is outlined in red. Figure 2. Dimensions on 1st Amended Plat. 8 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 4 of 14 The applicant has stated the existing water treatment facility has inadequate resources and space for the water treatment process, equipment, and staff. The proposed improvements are part of the Utility Department’s Master Planning Process to better facilitate current operations and anticipated future needs. This proposal includes upgrades to existing infrastructure, a new vehicle storage and maintenance facility, and expansion of water treatment facilities. The proposed improvements include: • Leonard Thomas Reservoir Expansion • Expansion of the Administration Building • New Vehicle Maintenance and Storage Facility • Addition to West Plant Building • Expand Residual Treatment Area A Phasing Plan is proposed in order to reduce disruption to the operations, allow for further refinement of the design of the reservoirs with the State Engineers Office, and allow for funding mechanisms to be in place for each phase prior to construction. The proposed phasing plan includes: • Phase 1 - 2020: o Vehicle Maintenance and Storage Facility • Phase 2 - 2021-2022: o Backwash Pond Improvements o West Plant Expansion • Phase 3 - 2022- 2023 o Administration Expansion • Phase 4 - 2025+: o Reservoir Expansion A site plan depicting the proposed improvements are shown in Figure 3 below (improvements outlined in red and blue): 9 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 5 of 14 Figure 3: Proposed Site Plan Leonard Thomas Reservoir Expansion The Applicant proposes to increase raw water storage at the Leonard Thomas Reservoir. The proposed expansion includes an expansion of the existing reservoir to the northwest (Figure 4), and to create a second reservoir to the southeast of the existing reservoir (Figure 5). Figure 6 shows both reservoirs on site. The additional storage capacity is requested due to concerns of head-gates becoming unusable for short periods of time. Stated reasons the head-gates may be unusable include avalanche, wildfire, or contamination. Recent events in the Roaring Fork Valley, including the Lake Christine Fire and this past winter’s avalanche cycle, have caused staff to evaluate and seek to improve operational resiliency. The Applicant is prepared to discuss the need and reasoning behind the proposed reservoir improvements at the hearing, if needed. 10 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 6 of 14 Figure 4 Existing Reservoir Expansion Figure 5 Reservoir Expansion – Second Reservoir 11 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 7 of 14 Addition to Administration Building A ~1,500 square foot expansion is proposed. The Applicant states the existing administration building is not large enough to accommodate all employees. Currently, some employees are working in a temporary job trailer on site. The proposed addition would allow all employees to work in an adequately sized administration building. The administration building sits on a water storage tank used in the treatment process and the proposed addition would expand above this storage tank. Given that the water storage tank is below the administration offices, the proposed remodel of the upper level would not increase the footprint of the structure (see proposed addition below in Figure 7, 8 and 9). Figure 7: Existing Administration building Figure 8: Proposed Admin. Building shown in red (Looking Southeast) Figure 6 Reservoir Expansion – Both Reservoirs Shown 12 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 8 of 14 Figure 9: Proposed Administration Building (materials to match existing) New Vehicle Storage and Maintenance Facility A ~3,200 square foot vehicle maintenance and storage building is proposed, shown in figures 10 & 11.The pre- fabricated building will be located to the southeast of the existing electric and distribution building. Currently vehicle maintenance and storage happen in other facilities or outside. The use of other facilities for the maintenance and storage or vehicles limits the efficiency of the water treatment operations. Also, the outdoor storage of machinery and vehicles creates additional wear on equipment that is vital to the water treatment process. Figure 10: Rendering of Proposed Vehicle Storage and Maintenance Facility 13 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 9 of 14 Figure 11: Location of Proposed Vehicle Storage and Maintenance Facility West Plant Addition and Replacement of Chlorination Tanks A ~525 square foot addition is proposed on the west façade of the West Plant building, shown in Figure 12. The chlorination materials and equipment are currently located in the “Ex. Chlorine Building” and will be moved into the proposed addition. The “ex. Chlorine building” will no longer be used in the water treatment process in the same capacity. The purpose of the addition, and relocation of equipment and materials, is to allow for more efficient operations. Current operations include moving materials between the Ex. Chlorine Building and the West Plant building during the water treatment process. During the winter months this can be problematic. The proposed addition will allow all equipment and materials to be located within the same structure. Figure 12: West Plant Addition and Replacement of Chlorination Structure and Tanks 14 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 10 of 14 The final request is for an additional backwash pond and improvements to the existing “south” backwash pond. Additional facilities for water processing require additional backwashing capacity. The proposal includes a second backwash pond to the north of the existing pond, expansion of the existing pond, repair and armoring of existing pond embankments, and improvements to a de-watering bed (see Figure 13). The Utilities Department plans to phase the construction of the requested improvements. Some elements, like the proposed vehicle storage and maintenance facility, are more immediate. The expansion of the Leonard Thomas Reservoir will commence at a later date. All improvements are requested to accommodate existing operations, future needs of the facility, and anticipated demand. STAFF EVALUATION: Public Project (Exhibit A): The proposed facility is subject to Major Public Project review. The Public Project review process was adopted by City Council in December 2015 to bring the Land Use Code into compliance with Colorado Revised Statute §31-23- 209. Public Project review is an alternative process for development projects submitted by governmental entities, quasi-municipal organizations, or public agencies providing essential services to the public. The review process includes a requirement to provide a decision within 60 days of application. The proposed development complies with multiple stated community goals from the Aspen Area Community Plan (AACP). Those specific goals are discussed in Exhibit A. The proposed development is compatible with the PUB zone district and the existing uses on the property. Based on initial review by the Development Review Committee, the application will comply with all applicable section of the Municipal Code, including Land Use Code regulations. The following chapters of the Land Use Code also apply to the proposed project: Planned Development, 8040 Greenline (ESA), Growth Management, and Transportation and Parking Management, Conditional Use Review. Staff responses to each section are detailed in Exhibits A-F, with specific highlights noted in the sections below. Planned Development (Exhibit B): The Public zone district requires the property proceed through a Planned Development review to establish dimensional requirements. Typically, Planned Development review is a two-step process including Project Review (uses, layout, mass scale, dimensions) and Detailed Review (landscape, fenestration, materials, lighting). As a Public Project, Project Review and Detailed Review are consolidated into one review, with a recommendation from P&Z and final approval on all aspects of the project from City Council. Overall, Staff is supportive of the proposal. Because of the expedited review process required by Major Public Project Review, a number of details that would normally be immediately resolved are still being discussed Figure 13: Backwash Pond Area Proposed Site Plan and Improvements 15 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 11 of 14 and refined. These issues have been identified by City referral agencies and will continue to be negotiated with the Applicant as the project moves toward building permit issuance. Addressing these unresolved design issues constitute the bulk of the recommended conditions of approval. A table listing proposed dimensional limitations is proposed below: Dimensions Proposed Lot Area 49.705 acres (2,165,149.8 sq. ft.) Maximum height 25 feet Front yard setback 100 feet Rear yard setbacks 100 feet Side yard setbacks 100 feet Allowable FAR (floor area ratio) 0.08:1 Off-street parking spaces 22 spaces Table 1: Proposed Dimensional Limitations The Applicant is continuing to work through floor area drawings to determine the gross floor area for the site. Based on initial review by the Zoning Department, there is ample floor area available for the proposed developments. City staff has requested more detailed depiction of existing floor area in order to accurately document existing conditions, including the proposed development. The SPA required 11 onsite parking spaces, but twenty-two (22) exist on site. The number of existing parking spaces (22) are shown in the table above. All dimensional limitations will be enumerated in the final ordinance, if approved, for clarity. The proposed development complies with all other dimensional limitations established through the SPA and subsequent amendments. 8040 Greenline Review, ESA (Exhibit C): The proposed project is entirely above the 8040 Greenline. As such, it is subject to review criteria outlined in 26.435.030.C. The majority of facilities and infrastructure already exist on site. Access will not change and an increase in allowable height is not requested. The site has been determined to be a suitable location for the proposed use. The Applicant is working with the State Engineers Office, specifically the Dam Safety Engineers, to ensure that any hazards that result from the proposed reservoirs, ponds and facilities are adequately mitigated. The Applicant is proposing to phase the development of the reservoirs, beginning in 2025, and as a result, the approval and permitting process has not yet been started with the State Engineers office. The 8040 Greenline review criteria considers impacts to the land and the visual impact of the development because of the prominent location above the elevation of 8040 feet above sea level. The proposed development is concentrated around existing infrastructure and all efforts are being made to minimize the impacts of grading and the disturbance to the terrain. The project requires a significant amount of earthwork, however, the Applicant has been working with the Parks and Engineering Departments to ensure the disturbance to the site is minimal. Staff has found the proposal to comply with the requirements of the 8040 Greenline review criteria. 16 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 12 of 14 Growth Management (Exhibit D): The proposed project has been determined as an essential public facility. With regard to Growth Management, there are two unique features of essential public facilities: 1. There is no annual allotment limit. 2. Employee generation is determined by P&Z or HPC. City Council may then assess, waive, or partially waive any mitigation requirement. Although employee generation is determined by P&Z, the Public zone district provides for an employee generation rate of 5.1 employees per 1,000 square feet of net leasable area. This generation rate was evaluated for office uses only and is not always appropriate for facilities with other purposes such as a maintenance garage. As such, the Code allows each Essential Public Facility proposal to be evaluated for actual employee generation. The application provides a current number of 26.5 employees that are working in the existing water treatment facility with no immediate plans to increase this number (detail shown in Figure . The proposed improvements will accommodate existing operations and staff. The Utilities Department does not intend to generate any additional employees as a result of the proposed improvements. APCHA staff has evaluated the request and recommends an audit of current employees be completed prior to issuance of a building permit and at two years after the issuance of the Certificate of Occupancy.

Planning staff concurs with APCHA’s recommendation and recommends that P&Z support this determination of no additional employees generated and the audit procedures. Should the P&Z have questions on generation, the applicant will be at the hearing to provide clarifications. Transportation and Parking Management (Exhibit E) This project requires a Level One Transportation Impact Analysis (TIA). The TIA outlines appropriate mitigation requirements using the Transportation Demand Management (TDM) and Multi-Modal Level of Service (MMLOS) toolkits. The Applicant submitted a Level 1 TIA. Engineering, Transportation and Planning Staff have determined the submitted plan does not satisfy the requirements of the TIA. Many of the improvements proposed already exist or are not practical give the restricted pedestrian access to the site. The Applicant will continue to work with the Engineering and Transportation departments to satisfy the TIA requirements prior to building permit issuance. More information will need to be provided prior to Council Review at Second Reading. This condition will be included in the draft ordinances for City Council. The Applicant has submitted a site plan showing twenty-two (22) parking spaces. The site is required per the SPA to have eleven (11). Staff recommends the P&Z review the existing parking and consider the additional parking demands generated by the development. If the P&Z determines additional on-site parking shall be required, the P&Z can make a recommendation to City Council to amend the parking minimum outlined for the SPA. Staff recommends the twenty-two (22) existing parking spaces be formalized and enumerated in the final Council ordinance. Conditional Use (Exhibit F) Conditional Use review is required for the vehicle maintenance and storage facility. The Conditional Use Review considers if the proposed uses conform with the intent of the zone district including compatibility with existing development and the surrounding area. The vehicle maintenance and storage facility is accessory to, and in support of, the primary use of the property as a water treatment facility. The proposed development is consistent with the design, bulk and mass of existing development. Vehicle maintenance and storage already occurs on site, and the proposed structure would improve existing operations and improve efficiency. The additional impacts of this use will be minimal. Staff is supportive of the Conditional Use and recommends that P&Z recommend approval to City Council of the Conditional Use request. REFERRAL DEPARTMENTS: The application was reviewed by APCHA, Engineering, Building, Zoning, Parks, Transportation, Environmental Health, Parking, the Aspen Consolidated Sanitation District, and the Aspen Fire District. The Development Review Committee met with the Applicant and provided comments at a meeting on July 10, 2019. All comments have either been addressed or will be conditions of approval that must be met at a later date. All received comments are included in Exhibit G, with applicable recommended conditions of approval included in the Draft Resolution. STAFF RECOMMENDATION: 18 Water Treatment Plant Planning and Zoning Commission Review Staff Memo 8.6.19 Page 14 of 14 Staff recommends that P&Z approve Resolution No. 10, Series of 2019 providing a recommendation of approval for the water treatment plant facility to City Council, subject to the following conditions: 1. The Applicant shall provide an employee audit to the satisfaction of the Aspen Pitkin County Housing Authority (APCHA) and Community Development Director documenting existing and proposed employees prior to issuance of the building permit. On the second anniversary of the Certificate of Occupancy the Applicant shall submit to APCHA an additional audit documenting employee generation. Additional subsequent audits may be requested at the discretion of APCHA. Any additional employees generated shall require the provision of affordable housing mitigation at the rate in effect at the time of the audit. 2. The Applicant shall work with the City Parks Department to ensure the proposed improvements minimize impacts to mature native gamble oaks identified on a site visit with the City Forester. The Applicant will be required to submit a tree removal permit, along with six (6’) foot tall fence shown for tree protection fencing around all impacted trees. The Applicant shall work with the Parks Department prior to approval of the final resolution by City Council to ensure the proposed reservoirs do not negatively impact the existing trails on site. 3. The Applicant shall work with the City Engineering and Transportation Departments, to satisfy the requirements of the Level 1 Transportation Impact Analysis, including the Transportation Demand Management (TDM) and Multi-Modal Level of Service (MMLOS) worksheet, prior to building permit issuance. Note: If the Planning and Zoning Commission determines additional employees are generated as a result of the proposed development, the number of employees generated must be included in the resolution.

Staff finds this criterion to be met. 38 Exhibit D – Growth Management Page 3 of 5 26.470.110.D. Essential public facilities. The development of an essential public facility, upon a recommendation from the Planning and Zoning Commission, shall be approved, approved with conditions or denied by the City Council based on the following criteria: a. The Community Development Director has determined the primary use and/or structure to be an essential public facility (see definition). Accessory uses may also be part of an essential public facility project. Staff Findings: The proposed project’s primary use has been determined by the Community Development Director to be an Essential Public Facility that meets the definition: “A facility which serves an essential public purpose, is available for use by or benefit of, the general public and serves the needs of the community.” A vehicle maintenance and storage facility is also proposed, which requires conditional use approval. The conditional use review will happen concurrently with all reviews. Staff finds this criterion to be met. b. Upon a recommendation from the Community Development Director, the City Council may assess, waive or partially waive affordable housing mitigation requirements as is deemed appropriate and warranted for the purpose of promoting civic uses and in consideration of broader community goals. The employee generation rates may be used as a guideline, but each operation shall be analyzed for its unique employee needs, pursuant to Section 26.470.100, Calculations. Staff Findings: The P&Z will review the project and determine the employee generation of the project. The Applicant has represented 26.5 employees exist, and no additional employees will be generated as the development will support existing operations. If the P&Z determines the proposed development generates additional employees, the applicant is requesting City Council waive any affordable housing mitigation. APHCA has recommended the applicant mitigate for any additional employees generated. Staff finds this criterion to be met. c. The applicant has made a reasonable good-faith effort in pursuit of providing the required affordable housing through the purchase and extinguishment of Certificates of Affordable Housing Credit. Staff Findings: Staff finds this criterion to be not applicable. d. The proposal furthers affordable housing goals, and the fee-in-lieu payment will result in the near-term production of affordable housing units. Staff Findings: No fee-in-lieu is requested, the Applicant is requesting any affordable housing mitigation requirements be waived by City Council. Staff finds this criterion to be not applicable. The City Council may accept any percentage of a project's total affordable housing mitigation to be provided through a fee-in-lieu payment, including all or none. Unless otherwise required by this Title, the provision of affordable housing mitigation via a fee -in-lieu payment for 0.25 FTEs or less shall not require City Council approval. 39 Exhibit D – Growth Management Page 4 of 5 26.470.050.C Employee generation. Applicants may request an employee generation review with the Planning and Zoning Commission, pursuant to Section 26.470.110, Growth management review procedures, and according to the following criteria. All essential public facilities shall be reviewed by the Planning and Zoning Commission to determine employee generation. In establishing employee generation, the Planning and Zoning Commission shall consider the following: a) The expected employee generation of the use considering the employment generation pattern of the use or of a similar use within the City or a similar resort economy. Staff Findings: The Land Use Code identifies an employee generation rate of 5.1 FTEs per 1,000 sq. ft. of net leasable space for the Public zone district. However, this generation rate is specific to office uses only. While this facility has some office use, much of the floor area is given to vehicle storage and other uses. In the case of Essential Public Facilities, the Land Use Code allows for the evaluation of actual employee generation – in this case the applicant has initially identified 26.5 employees. The Applicant claims no additional employees will be generated and that will be verified by an audit performed prior to building permit issuance and two years after the issuance of a certificate of occupancy. Staff finds this criterion to be met. b) Any unique employment characteristics of the operation. Staff Findings: Because of the unique nature of this facility, staff finds it appropriate to use actual employees to determine employee generation. c)The extent to which employees of various uses within a mixed-use building or of a related off-site operation will overlap or serve multiple functions. Staff Findings: Staff finds this criterion to be not applicable. d) A proposed restriction requiring full employee generation mitigation upon vacation of the type of business acceptable to the Planning and Zoning Commission. Staff Findings: There is no proposed restriction for the proposal as this is anticipated to serve as government facility indefinitely. e) Any proposed follow-up analyses of the project (e.g., an audit) to confirm actual employee generation. Staff Findings: APCHA has recommended, and Planning Staff concurs, that an audit of employees is required prior to issuance of a building permit and two years after receipt of the certificate of occupancy. Staff finds this criterion to be met. f) For lodge projects only: An efficiency or reduction in the number of employees required for the lodging component of the project may, at the discret ion of the Commission as a means of incentivizing a lodge project, be applied as a credit towards the mitigation requirement of the free-market residential component of the project. Any approved reduction shall require an audit to determine actual employee generation after two (2) complete years of operation of the lodge. 40 Exhibit D – Growth Management Page 5 of 5 Staff Findings: There is no lodge component to this project. Staff finds this criterion to be not applicable. 41 Exhibit C – Transportation and Parking Management Page 1 of 2 EXHIBIT E TRANSPORTATION AND PARKING MANAGEMENT 26.515.060.C. Review Criteria. All applicable projects are required to submit a Mobility Plan, which shall include and describe a project’s mitigations for TIA and Parking Requirements. The Engineering, Transportation, and Community Development Department staff shall determine whether the project conforms to this Chapter requirements using the following standards: 1. Project TIA and the resulting mitigation program meets requirements for exempt, minor, or major project categories as outlined in the TIA Guidelines. Staff Findings: The proposed project is considered a minor development outside the roundabout and is required to complete a Level One TIA. The Applicant’s TIA and TDM/MMLOS submission is not complete. The Applicant will work with the Engineering and Transportation Departments to ensure compliance with the transportation requirements prior to building permit issuance. Staff finds this criterion to be met, with conditions. 2. Project provides full mitigation for the Parking Requirements pursuant to Section 26.515.050. Staff Findings: The parking requirements are established through the Planned Development Process. The original SPA required 11 on site parking spaces. The Applicant will be required to provide at least 11 parking spaces. Currently 22 parking spaces exist on site, staff recommends the existing conditions be enumerated in the final ordinance to be approved by City Council. Staff has determined that the proposed development does not result in increased parking demands and does not recommend additional parking spaces be provided as a result of the proposal. Staff finds this criterion to be met. 3. If existing development is expanded, additional Parking Requirements shall be provided for that increment of the expansion. Staff Findings: The proposed development does not increase employees and supports existing operations. Staff does not believe that increased parking requirements are needed. Staff finds this criterion to be met. 4. If existing development is redeveloped, on-site parking deficits may not be maintained unless all parking, or at least 20 spaces are provided as Public Parking. Projects failing to meet the requirements of this section may apply for a variation to the Planning and Zoning Commission through the Special Review process (Section 26.430 and Section 26.515.080). Staff Findings: The proposed development does not maintain a parking deficit. Staff finds this criterion to be not applicable. 42 Exhibit C – Transportation and Parking Management Page 2 of 2 26.515.080. Special Review Standards. Whenever the transportation, mobility, and parking impacts of a proposed development are subject to special review, an application shall be processed as a special review in accordance with the common development review procedures set forth in Chapter 26.304 and be evaluated according to the following standards. Review is by the Planning and Zoning Commission. If the project requires review by the Historic Preservation Commission and the Community Development Director has authorized consolidation pursuant to Subsection 26.304.060.B, the Historic Preservation Commission shall approve, approve with conditions or disapprove the special review application. A special review for establishing, varying or waiving transportation, mobility, or off-street parking requirements may be approved, approved with conditions or denied based on its conformance with all of the following criteria: 1. The transportation, mobility, and off-street parking needs of the residents, customers, guests and employees of the project have been met, taking into account potential uses of the parcel, the projected traffic generation of the project, any shared parking opportunities, expected schedule of parking demands, the projected impacts on the on - street parking of the neighborhood, the proximity to mass transit routes and the downtown area and any special services, such as vans, provided for residents, guests and employees. Staff Findings: As mentioned, the applicant’s TIA and TDM/MMLOS submission are not sufficient. The Applicant will work with Transportation and Engineering staff to identify and implement appropriate mitigation strategies to enhance possible on-site pedestrian, bicycle and transit facilities. Staff finds this criterion to be met, with conditions. 2. An on-site mitigation solution meeting the requirements and guidelines is practically difficult or results in an undesirable development scenario. Staff Findings: There are numerous options for meeting mitigation options on-site. Criterion is not applicable. 3. Existing or planned on-site or off-site facilities adequately serve the needs of the development, including the availability of street parking. Staff Findings: The end outcome of the new facilities will not generate new demands for parking, but will require the redesign of on-site multi-modal facilities. Street parking is not available. Staff finds this criterion to be met, with conditions. 43 Exhibit C – Conditional Use Review Page 1 of 2 EXHIBIT F CONDITIONAL USE 26.425.040. Standards applicable to all conditional uses. When considering a development application for a conditional use, the Planning and Zoning Commission shall consider whether all of the following standards are met, as applicable. A. The conditional use is consistent with the intent of the Zone District in which it is proposed to be located and complies with all other applicable requirements of this Title; and Staff Response: The proposed vehicle storage and maintenance facility is accessory to, and in support of, the primary operation of the water treatment facility as an essential government facility that provides utilities and services for the community. It is compatible with the Public (PUB) zone district, staff finds this criterion to be met. B. The conditional use is compatible with the mix of development in the immediate vicinity of the parcel in terms of density, height, bulk, architecture, landscaping, and open space, as well as with any applicable adopted regulatory master plan. Staff Response: The structure is compatible with the other structures on the Water Plant SPA site. The proposed structure is located in proximity to existing buildings and has a minimal impact on the open space of the property, Staff finds this criterion to be met. C. The conditional use is consistent and compatible with the character of the immediate vicinity of the parcel proposed for development and surrounding land uses and enhances the mixture of complimentary uses and activities in the immediate vicinity of the parcel proposed for development; and Staff Response: The proposed vehicle maintenance and storage facility is consistent and compatible with the use and existing development on site. The structure is used to support and improve existing operations, which are consistent with the intended uses of the PUB zone district, Staff finds this criterion to be met. D. The location, size, design and operating characteristics of the proposed conditional use minimizes adverse effects, including visual impacts, impacts on pedestrian and vehicular circulation, parking, trash, service delivery, noise, vibrations and odor on surrounding properties; and Staff Response: The location, size, operational characteristics, and design are all compatible with existing development on site and comply with the adopted dimensional limitations established by the zone district. The proposed structure will not increase pedestrian or vehicular circulation , or other impacts to the surrounding properties, as the structure supports existing infrastructure and operations. Staff finds this criterion to be met. E. There are adequate public facilities and services to serve the conditional use including but not 44 Exhibit C – Conditional Use Review Page 2 of 2 limited to roads, potable water, sewer, solid waste, parks, police, fire protection, emergency medical services, hospital and medical services, drainage systems and schools; and Staff Response: There are adequate public facilities and services in place to accommodate the proposed conditional use structure. Any additional impacts of the proposed development will be upgraded at the Applicant’s expense and will comply with all adopted regulations of the City of Aspen, Pitkin County, and State of Colorado. Staff finds this criterion to be met. F. The applicant commits to supply affordable housing to meet the incremental need for increased employees generated by the conditional use; and Staff Response: The proposed development will not result in additional employees, rather, the proposed development supports existing operations and employees. Staff finds this criterion to be not applicable. G. The Community Development Director may recommend and the Planning and Zoning Commission may impose such conditions on a conditional use that are necessary to maintain the integrity of the City's Zone Districts and to ensure the conditional use complies this Chapter and this Title; is compatible with surrounding land uses; and is served by adequate public facilities. This includes, but is not limited to, imposing conditions on size, bulk, location, open space, landscaping, buffering, lighting, signage, off-street parking and other similar design features, the construction of public facilities to serve the conditional use and limitations on the operating characteristics, hours of operation and duration of the conditional use. Staff Response: The proposed structure is compatible with the existing use and operations of the Water Treatment Plant and enhances existing operations. The Community Development does not recommend any additional conditions on the proposed vehicle storage and maintenance facility at this time. Staff finds this criterion to be not applicable. 45 EXHIBIT G DRC REFERRAL COMMENTS The Development Review Committee met with the Applicant to discuss the proposed project on Wednesday, July 10th in Council Chambers. Representative of the following referral agencies were present: Engineering, Building, APCHA, Zoning, Environmental, Aspen Fire District, and Parking. The Environmental Health and Parks Departments have provided comment but were not present at the meeting. Pitkin County Community Development reviewed the application and did not submit comments. The Transportation Department coordinated with Engineering and their comments were combined with Engineering. The following comments were provided by referral agencies: Engineering Comments – provided by Hailey Guglielmo These comments are not intended to be exclusive, but an initial response to the project packet submitted for purpose of the DRC meeting. The TIA needs to be finalized prior to approval of the land use case. 1. The narrative starts to say two pedestrian improvements will be completed further down on Doolittle, but it does not specify what those improvements will be. 2. The property cannot receive credit for programs that are already in place. The bus subsidy is an existing strategy. Are the bike racks, showers, and lockers already existing? What is the proposed improvement to the employee shuttle van situation? How does it go above and beyond what is already being done? The following items should be included/addressed at building permit. 1. Andy Rossello stated the project team is working with the CDPHE for all dam and reservoir permitting requirements. At building permit please provide this information to the City Engineering Department. In particular the analysis of an emergency spillway and any potential impacts to downstream properties. 2. The engineering drainage report should include an analysis of the drainage path all the way to Castle Creek Bridge. Is the culvert under Castle Creek road adequately sized? 3. The project will need to provide detention or show the system to the river is sized for the 100 - year event. Andy mentioned using the backwash pond for stormwater detention. This may have been done for previous projects. If the backwash pond is utilized it needs to be analyzed for the whole site to see if there is capacity. 4. Drywells are the BMP of last resort. If there is adequate space for a sand filter or bioretention area that should be implemented. 5. Any addition to structures will need to be designed to collect stormwater and treat for WQCV. The property is only required to treat new additions. . Building Comments – provided by Denis Murray - An oil and sand separator are required in the vehicle maintenance and storage facility. - Snow stops will be required as applicable. 46 - A building permit shall not be issued unless the project is in compliance with policies and codes as currently adopted and amended per Title 8 (Building and Energy Codes) of the Aspen Municipal Code. Including Ordinance 40, Series of 2016 and Colorado Revised Statues 9-5-101, as well as any applicable building codes in place at the time of permit submission. Parks Comments – provided by David Radeck: Parks comments would be that we would like to minimize impacts to the native gamble oak stand that would be impacted due to the increase of the size of the ponds. Other than that, a tree removal permit would be required along with a 6’ tall fence for tree protection fencing around all impacted areas. Parks would like to see what impacts if any would be to the trail just above the proposed expansion of the pond as well. Comments from Environmental Health and Sustainability – provided by Liz O’Connell Chapman I am unable to attend this DRC. I have a had a look at the plans and I cannot tell what size or configuration the trash enclosure will be. As long as they meet code and provide 200 SF of accessible trash and recycling storage, it’s probably going to be good. I will need to see more detail about the size, placement, and configuration before I can approve. Aspen Fire District comments – provided by Parker Lathrop None Zoning Comments – provided by Bob Narracci 1) With the building permit application, please provide all math demonstrating how maximum allowable Floor Area was derived. On Sheet 38, the existing and proposed tables convey considerably different allowable Floor Area numbers. (Page 5, Sheet 38) a. This PD Amendment is an opportunity to clearly specify maximum floor area allowances for the Water Plant SPA/PD; b. The proposed pump station building should be included in the Floor Area calculations; c. It does not appear that floor area calculations have been provided for the proposed new maintenance garage. d. Unless this project is exempted from impact fees by Council, please provide the existing and proposed net-leasable calculations for all existing and proposed buildings on the Water Plant site. This will be necessary for impact fee calculations at the time of building permit. 2) The PD calls out a minimum 100-foot setback from the property boundary. Not all the existing and proposed improvements are within the 100-foot setback. (Sheet 32) a. The PD Amendment process is an opportunity to either specify a lesser setback, and/or define separate setbacks for the buildings versus the ponds, pump station and other ancillary improvements. b. The Verizon cell site does not appear to satisfy the 100-foot setback. An as-built setback could be called out in the PD. 47 3) All exterior stairs count towards ‘deck’ area. If all the deck area is less than 15% of the total allowable floor area, then it is exempt. (Sheet 38) APCHA Comments – provided by Cindy Christensen, ISSUE: The applicant is seeking approval to provide a new vehicular storage garage, and updating and expanding several key water treatment facilities, including the administrative office. BACKGROUND: The application has been submitted as an Essential Public Facility under the Land Use Code. Chapter 26.445.110, C., states: “Employee generation review. All Essential Public Facilities shall be reviewed by the Planning and Zoning Commission to determine employee generation, pursuant to Section 26.470.110D. In addition, any applicant who believes the employee generation rate is different than that outlined herein may request an employee generation review with the Planning and Zoning Commission during a duly noticed public hearing, pursuant to Section 26.304.060.E.” Per the applicant, it is not anticipated that additional employee generation will result from the upgrades provided for in this application. Chapter 26.470.080, D, 6) Affordable Housing Mitigation for Essential Public Facility development, states that mitigation shall be determined based on section 26.470.110.D. Chapter 26.470.110.D. allows the City Council to waive or partially waive affordable housing mitigation requirements as is deemed appropriate upon recommendation from the Community Development Director and the Planning and Zoning Commission. SUMMARY: Based on the Land Use Code, the Planning and Zoning Commission reviews the application and decides on any mitigation requirement. APCHA RECOMMENDATION: Staff recommends that the Planning and Zoning Commission request an employee audit prior to building permit approval, showing the hours of all employees in the Water Department and then dividing by 2,080 hours for a Full-Time Equivalent (FTE) count. After two years from the Certificate of Occupancy (CO), another employee audit shall be conducted to see if any FTE’s were added. If at such time employees were added, it is recommended that mitigation be required. Mitigation can be satisfied from the credits the City of Aspen may have from their specific housing fund.

This application has been prepared in conformance with the City of Aspen Pre- Application Conference Summary dated 8 March 2018, made a part of this application as Attachment 14. The Property consists of approximately 50 acres and is located outside the Aspen Infill Area. Underlying zoning is the Public (PUB) zone district with a Planned Development (PD) Overlay. Existing uses include City of Aspen water treatment facility. Proposed Development The Applicant proposes providing a new vehicular storage garage and updating and expanding several of the key water treatment facilities, including the administrative office, as part of a master planning process for the water plant facilities. Specific proposed modifications and additions to the existing facilities include:  Reservoir expansion for surface area and volume – The City Utilities Department is planning the expansion of the Leonard Thomas Reservoir, an on-site body of water providing approximately 10 acre-feet of raw water storage upstream of the City’s Castle Creek Water Treatment Plant. Reservoir expansion alternatives include a new earth dam or concrete reservoir located to the south of the existing reservoir or expanding the surface area of the existing body of water to the northeast. The attached Master Planning Exhibit shows the potential locations of both reservoir expansion options;   Expansion of the existing administration building - The 1,499 SF expansion will provide additional administrative office space to the west of the existing building. The design of the addition will match the existing building;  New maintenance and vehicle storage structure - The new maintenance and vehicle storage structure, which will be used to store heavy equipment currently stored outside, will be approximately 3,200 SF. The pre-fabricated building will be located to the southeast of the existing Electric and Distribution Building and will include a shed roof, possibly OV panels, and a concrete access apron;  New chlorination structure and tanks – Replacement of the existing chlorination tanks and structure with a new approximately 525 SF structure adjacent to the West plant;  Expansion of Residual Treatment Area – The City Utilities Department currently uses a portion of the Thomas Parcel to treat residuals produced from its WTP process. Spent filter backwash and residuals collected in settling process are sent to an existing holding pond. The residuals sent to this pond settle within the pond and the clarified water overflows to Castle Creek and/or Holden-Marolt Ditch. Residuals accumulate in the pond over time and are periodically removed by dredging the pond and drying those dredged residuals within a geosynthetic textile bag called a GeoTube. The residuals within the Geotube are allowed to dry and sent to the landfill for disposal. The City Utilities Department is planning the following improvements to this area: 52 City of Aspen Water Department, Lot 25, Water Treatment Plant Site 6 June 2019 Page | 5    Construction of a second, lined holding pond.  Expansion of the existing holding pond and dewatering Geotube area.  Lining and improving existing pond embankment. These improvements are necessary for the current operations of the water plant and anticipated future needs of this Essential Public Facility. Previous Approvals Ordinance 7, Series of 1980 created the original City Water Plan Specially Planned Area (SPA) designation. A series of amendments have occurred since 1980 with the most significant amendment occurring in 1996 that granted Final SPA approval, Subdivision, Conditional Use Approval for Affordable Housing in the Public Zone District, Special Review for Parking, Open Space and Dimensional Requirements for Affordable Housing, 8040 Greenline Review, and GMQS Exemption for twenty-three (23) Affordable Housing units. The Affordable Housing units, known as the Water Plan Affordable Housing, have been subdivided and are no longer a part of the Property. The City Thomas Property Subdivision Exception, Lot 4, Specially Planned Area Map, dated 27 March 1984 provided the following SPA data: o Area of Lot: 54.36 ac o Existing Area Developed: 3.83 ac o Total Floor Area Ratio: 14:1 o Proposed Water Plant Development: .77 ac o Proposed Floor Area Ratio: 11.82:1 o Minimum Development Set Back: 100 feet (all sides) o Maximum Height of Structures: 25 feet o Minimum Parking:  Water Treatment Plant and Officer: 6 spaces  Water Maintenance Building: 3 spaces  Caretakers House: 2 spaces (no caretake house provided nor proposed at this time) o Open Space as Developed: 50.53 ac o Open Space After Proposed Development: 49.76 ac o Open Space % of Lot After Development: 91.54% We look forward to working with the City of Aspen Community Development Department, the City of Aspen Planning and Zoning Commission, and the City of Aspen City Council in connection with this application. 53 City of Aspen Water Department, Lot 25, Water Treatment Plant Site 6 June 2019 Page | 6   Code Response 26.304.035 Neighborhood Outreach In addition to traditional public noticing requirements and in order to facilitate citizen participation, the Applicant proposes a public outreach meeting to review the proposed development. A written summary of the neighborhood outreach meeting, including any documentation that was presented to the public as part of the outreach, as well as the method of public notification, will be prepared by the Applicant and will be submitted as part of the official record. 26.435.030 8040 Greenline Review A.

Review Criteria. All development and redevelopment projects are required to submit a Mobility Plan, which shall include and describe a project’s mitigations for TIA and Parking Requirements. The Engineering, Transportation, and Community Development Department staff shall determine whether the project conforms to this Chapter requirements using the following standards: 1. Project TIA and the resulting mitigation program meets requirements for exempt, minor, or major project categories as outlined in the TIA Guidelines. The Level One TIA included with this application illustrates compliance with all requirements for major project categories. 2. Project provides full mitigation for the Parking Requirements pursuant to Section 26.515.050. The project will fully meet required parking onsite. 3. If existing development is expanded, additional Parking Requirements shall be provided for that increment of the expansion. Parking will be provided for any incremental expansion of development, as required. It is not anticipated that additional parking will be required as proposed development will be in support of existing activities. 4. If existing development is redeveloped, on-site parking deficits may not be maintained unless all parking, or at least 20 spaces are provided as Public Parking. Not applicable Projects failing to meet the requirements of this section may apply for a variation to the Planning and Zoning Commission through the Special Review process (Section 26.430 and Section 26.515.080). Applicable parking requirements will be met onsite and a variance is not anticipated to be required at this time. 26.515.070. Off-Street Parking Requirements. A. Applicability. Where off-street parking spaces are provided as part of a Mobility Plan, the regulations in Sections 26.515.070.(B – I) apply. The proposed development does not include off-street parking. 26.575.020 Calculations and Measurements A. Purpose. This section sets forth methods for measuring floor area, height, setbacks, and other dimensional aspects of development and describes certain allowances, requirements and other prescriptions for a range of structural components, such as porches, balconies, garages, chimneys, mechanical equipment, projections into setbacks, etc. The definitions of the terms are set forth at Section 26.104.100 – Definitions. Floor area, height, setbacks, and other dimensional aspects of the proposed development will be provided pursuant to the Planned Development dimensional limitations. The area calculation sheets describe all allowances, requirements and other prescriptions for a range of 69 City of Aspen Water Department, Lot 25, Water Treatment Plant Site 6 June 2019 Page | 22   structural components, such as porches, balconies, garages, chimneys, mechanical equipment, projections into setbacks, etc. 26.600 Impact Fees and Dedications 26.610.010. Purpose and intent. For residents and visitors, parks and recreation facilities make up a significant part of the community character of the City. As a result of growth, increased pressure is placed on existing parks and recreation facilities necessitating acquisition of new park lands and development of additional recreation facilities in order to maintain the current level of service. In order to maintain the current community standards for acquisition of open space and development of parks and recreation facilities, the City finds it necessary to impose a Park Development impact fee on new development. Transportation demand management and air quality capital facilities ensure the mobility of residents, workers and visitors through multi-modal solutions, as well as clean air for the community. The Aspen Area Community Plan directs the City to maintain traffic levels at or below 1993 levels in order to protect our environment and quality of life, and the City has invested in capital facilities to do so. As new development and growth occur, increased pressure is placed upon our existing facilities, necessitating expansion of these capital facilities to maintain the current level of service. In order to maintain the current community standards for transportation demand management and air quality, the City finds it necessary to impose a Transportation Demand Management/Air Quality impact fee on new development. This Chapter is enacted for the purpose of implementing the City's plans for capital facilities by requiring that new development pay for its fair share of such facilities through the imposition of impact fees that will be used to finance, defray or reimburse all or a portion of the costs incurred by the City to serve new development. (Ord. No. 33, 2006, §1) 26.610.020. Applicability. Unless expressly exempted, the Park Development impact fee and the Transportation Demand Management (TDM)/Air Quality impact fee shall be assessed upon all development within the City which contains residential floor area or net leasable commercial space. The proposed development does not contain residential floor area nor net leasable commercial space; the proposed development is exempt. 26.610.100. Waiver of fees. Whenever the City Council determines that any part of a proposed development constitutes an affordable housing development or an Essential Public Facility, as defined by this Title, and wishes to subsidize the construction, the City Council may exempt that part of the development from the application of the impact fees or may reduce by any amount the fees imposed by this Chapter. As an economic development incentive, a lodging development may apply for a waiver of the impact fees. An application for a waiver must be made and acted upon by the City Council prior to the submission of a building permit application. Retroactive waivers are not permitted. The proposed development has been determined by Staff to be an Essential Public Facility. 26.620.020.030. School Land Dedication / Exemptions Any development considered nonresidential development, as defined by this Chapter, is exempt from the school land dedication. The proposed development does not contain residential floor area and is therefore considered nonresidential development that is exempt from school land dedications. 70 City of Aspen Water Department, Lot 25, Water Treatment Plant Site 6 June 2019 Page | 23   26.710.250 Public (PUB).

Purpose of Report This Engineering Report has been prepared in support of a Major Public Project Review for the proposed improvements located on Lot 25 of the Water Treatment Plant Site, 500 Doolittle Drive (Parcel ID: 273513204825). The information within this report presents our summary of preliminary engineering analysis and findings associated with serving the proposed improvements with required utilities as well as providing stormwater mitigation strategies per the requirements outlined within the City’s Urban Runoff Management Plan (URMP). Preliminary civil drawings have been included with this report for illustrative support of this document. B. Background & Existing Site Description The original City Water Plan Specially Planned Area was approved under Ordinance 7, Series of 1980. Several amendments to this Ordinance have occurred to include the City Thomas Subdivision Exception, Lot 4 SPA dated March 1984 and the most recent being the Final SPA Approval Subdivision in 1996. The City Water Department (Applicant) is currently seek ing to amend these previous approvals to provide some clarifications as well as planning for future expansions to support the water plant operations. The existing site sits on a flat bench above Castle Creek Road and encompasses approximately 50 acres. The property currently consists of several buildings, storage yards, parking, water storage reservoir, settling ponds and undeveloped areas. The improved areas are confined to an area consisting of approximately 5.5 acres. Ground cover in undisturbed areas consists of scrub oak and other native plants. Site topography generally slopes south to north on grades varying between 5%-35%. The steeper grades are associated with the hillside that lies southwest of the developed area while the flatter grades coincide with the operation facility of the water treatment plant. The site is a tributary drainage basin to Castle Creek which runs along the east side of the property. The site is bounded by Castle Creek Road on the east, Moore Family Subdivision & Meadowood Subdivision to the west, private property to the south and the Water Plant Affordable Housing Complex and Twin Ridge Subdivisions to the north. C. Project Summary The proposed improvements currently being considered at the City’s Water Plant include: 1. New Maintenance Garage: The Water Department is proposing the construction of a pre-fabricated building for vehicular storage and maintenance. The proposed location is southeast of the existing Electric and Distribution Building. The new building will be approximately 3,200 square feet and will include a shed roof, potentially PV panels, and a concrete access apron. 2. Reservoir Expansion: The City Utilities Department is planning the expansion of the Leonard Thomas Reservoir, an on-site body of water providing approximately 10 acre-feet of raw water storage upstream of the City’s Castle Creek Water Treatment Plant. Reservoir expansion alternatives include a new earth dam or concrete reservoir located to the south of the existing reservoir or expanding the surface area of the existing body of water to the northeast. The attached Master Planning Exhibit shows the potential locations of both reservoir expansion options. 3. Administration Building Expansion: Expansion of the existing Admin Building is desired to provide additional office space for existing employees. Currently, the expansion is being proposed on the east side of the building replacing an existing deck.

Expansion of West Plant: An expansion of the West Plant to house new sodium hypochlorite tanks is being proposed along the west side of the existing building. 5. Expansion/Improvements to Residuals Treatment Area: The City Utilities Department currently uses a portion of the Thomas Parcel to treat residuals produced from its WTP process. Spent filter backwash and residuals collected in settling process are sent to an existing holding pond. The residuals sent to this pond settle within the pond and the clarified water overflows to Castle Creek and/or Holden-Marolt Ditch. Residuals accumulate in the pond over time and are periodically removed by dredging the pond and drying those dredged residuals within a geosynthetic textile bag called a GeoTube. The resdiuals within the geotube are allowed to dry and sent to the landfill for disposal. The City Utilities Department is planning the following improvements to this area:  Construction of a second, lined holding pond.  Expansion of the existing holding pond and dewatering Geotube area.  Lining and improving existing pond embankment. 6. New Maintenance Garage: The Water Department is proposing the construction of a pre-fabricated building for vehicular storage and maintenance. The proposed location is southeast of the existing Electric and Distribution Building. The new building will be approximately 3,200 square feet and will include a shed roof, potentially PV panels, and a concrete access apron. All of the improvements outlined above are essential to current operations as well as anticipated future needs of the City’s water treatment facility. D. Site Utilities This Section outlines our findings as it relates to serving the proposed improvements with required utilities. A Conceptual Utility Plan has been included within the attached civil drawings for illustrative support. Final design information will be provided once Permit Applications are pursued. It is our understanding that the West Plant and the Administration Building will not require utility upgrades given the small expansions being considered. Also, utility services to the proposed reservoir expansion and/or residual treatment area are also not anticipated; therefore our utility evaluation outlined below is specific to the proposed Maintenance Garage. Water Service: The City of Aspen Water Department is the provider of potable water for the subject property. The proposed Maintenance Garage will require water service to serve a wash bay and a small sink. The current plan is to extend a new service from the West Plant to the proposed building as illustrated on the attached plan set. Final sizes, service alignments, meters, backflow preventers, boilers and other required appurtenances will be provided in support of any future Building Permit Application. 144 Engineering Report-Aspen Water Plant Major Public Project Review SE Job#19003 S OPR IS E N G IN E ER IN G • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 4 | P a g e Sanitary Sewer: Aspen Consolidated Sanitation District (ACSD) is the supplier of sanitary sewer service to the subject property and surrounding area. The ACSD currently has a mainline that runs along Doolittle Drive and terminates just north of the subject property. A shared service line extends from the mainline and serves several of the existing buildings located on site. Sewer service to serve the proposed Maintenance Garage will be extended from the existing service line. A few utility crossings are anticipated; however the new sewer service should be able to be routed under these existing lines. The need for a sand/oil separator is anticipated given the use of the proposed facility. The service alignment, utility crossings and the need for a sand/oil separator will be further evaluated as the project design progresses through the City’s review process with final designs being provided in support of any future Building Permit Applications. Shallow Utilities Shallow utilities serving the existing campus include electric, gas, fiber optic and telephone. The information provided within this section includes utility locates obtained during the improvement survey as well as discussions with the individual utility providers. Electric: Through coordination with the COA Electric Department we understand there is the possibility to connect to the meter currently serving the Electric & Distribution Shop Building; provided load demands are not too high. Since electric demands are not known at this time we are assuming that elec tric service will be extended from an existing transformer located at the northeast corner of the Raw Water Building as illustrated on the Conceptual Utility Plan. Once the final electric demands are determined the routing of the service line will be evaluated further with final designs being provided at time of Building Permit. Gas: Black Hills Energy is the provider of natural gas to the subject property via a 2” plastic main that runs up Doolittle Drive and extends through the site and ends north of the West Plant. There are several service taps that extend to the various buildings on site. Currently the plan is to extend a new service line to the proposed building and set a new meter. There is also an option of tapping off the existing meter serv ing the Electric and Distribution Building; this option will be further evaluated with Black Hills Energy and City Management prior to issuing any Building Permit. Telephone: CenturyLink is the provider of telephone to the subject property. A service line is extended from a connection point just north of the security gate on the west side of Doolittle Drive. If telephone service is determined to be necessary for the proposed Maintenance Garage a service line could be extended from one of the existing buildings that currently have telephone service. This will be further coordinated with Century Link as the design progresses. Comcast: It is our understanding that Comcast does not currently provide service to the subject property. Fiber Optic: City of Aspen fiber optic is currently available if it is determined to be needed for the proposed Maintenance Garage. E. Conceptual Drainage Analysis 145 Engineering Report-Aspen Water Plant Major Public Project Review SE Job#19003 S OPR IS E N G IN E ER IN G • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 5 | P a g e The intent of this section is to provide background drainage information of the subject property, describe the existing onsite and offsite drainage conditions as well as provide conceptual stormwater mitigation solutions, with a strong emphasis on water quality treatment, per the requirements outlined within the City’s URMP. Final details, construction documents and drainage report will be provided in support of any future Building Permit Application. Background: The subject property falls outside the City’s designated storm drainage system as described within the Surface Drainage Master Plan (SDMP) for the City of Aspen, dated November 2001 prepared by WRC Engineering, Inc. Our office prepared a Drainage Report dated March 21, 2012 (SE Job No. 12052) in support of a proposed pump station located on the subject property. In summary, the water quality treatment for the pump house was provided via conveyance over well vegetated ground cover before flows enter Castle Creek and stormwater detention was not required given the close proximity and direct connection to Castle Creek. The property is located in Zone X on FEMA Flood Insurance Rate Map panel number 08097C0203C with effective date of June 4, 1987. FEMA designates Zone X as being an area outside the 0.2% (500 year storm) annual chance floodplain. CTL Thom pson prepared a Geological and Geotechnical Evaluation and determined that “the site is not within any recognized geologic hazard area and the underlying soils consist of silty to clayey sand, underlain with silty sand, gravel and cobbles all of which exhibit good support characteristics for building st ructures.” Site runoff is routed through the site via surface runoff and shallow swales. Generally all offsite and onsite stormwater runoff is routed towards the existing backwash pond located at the northern end of the site which offers an opportunity for water quality treatment and stormwater detention. Flows are released from the backwash pond and routed over well vegetated ground cover and conveyed under Castle Creek Road and ultimately towards Castle Creek. Lastly, based on discussions with City Water Department staff, there are no known drainage issues on the subject property. Conceptual Stormwater Mitigation Design: SE has studied the proposed improvements and based on Table 1.1 of the City’s URMP we believe that collectively the improvements fall into the Major Project category to include landscaping, grading, installing new hardscapes, additions to structures, etc. >1000 Sq Ft and < 25% of the entire site which requires the following items:  CMP  WQCV for the new impervious area  Conveyance of major flows  Detention to the historic undeveloped rate or fee-in-lieu for the disturbed or added area, unless discharging directly to the City’s stormwater system or an established water way It is assumed that the proposed reservoir and residual treatment area will consist primarily of grading work and that no additional impervious areas will be created with these improvements; however this will be further 146 Engineering Report-Aspen Water Plant Major Public Project Review SE Job#19003 S OPR IS E N G IN E ER IN G • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 6 | P a g e evaluated as the designs progress and required stormwater mitigation will be addressed in support of any future Landscaping/Grading Permits. In addition, it is understood that water quality treatment will be required for any addition and/or expansion of the Admin Building and West Plant and that the design of stormwater mitigation for these components of the project will be addressed in support of any future Building Permit Application and therefore this section focuses on the stormwater mitigation recommendations for the Maintenance Garage. The drainage basin associated with the proposed Maintenance Garage was determined to be approximately 1.3 acres. This basin slopes from southwest to northeast. Conceptual grading has been performed for the proposed structure and consists of cutting into the existing hillside. A mechanically stabilized earthen wall (MSE) is being considered around the perimeter of the building to provide room for storing materials as well as serve as a shallow swale to convey runoff around the building. The proposed building will have a shed roof that pitches from the north to the south. This will result in maximizing the roof area for potential PV Panels. A concrete access apron is anticipated at the north end of the building. The concrete apron will include a drain pan that will direct runoff to the proposed stormwater treatment and detention infrastructure via overland flow, swales and storm pipes. The required water quality treatment volume associated with the proposed Maintenance Garage and upstream tributary area as well as the 10- and 100-year detention volumes have been estimated and are summarized within Table 1. Supporting calculations are provided as an attachment to this report. Table 1: Water Quality & Detention Volume Summary The information summarized within Table 1 was used to conceptually size and design stormwater mitigation infrastructure. In addition, integration of the proposed stormwater improvement options discussed below took into account existing operations of the facility. It should also be noted that although the site currently directs runoff towards Castle Creek and therefore stormwater detention is not necessarily required it is being considered to ensure existing downstream improvements are not adversely impacted by increased peak runoff rates and/or volumes. Below are a couple of options for providing the water quality treatment and stormwater detention volumes as outlined within Table 1. Sand Filter Basin: A sand filter basin is a stormwater treatment facility that is capable of providing water quality treatment by filtering captured stormwater runoff through a sand filter media. This particular type of BMP is also capable of providing detention storage. A potential location for a sand filter basin has been identified on the attached plan set and consists of approximately 250 square foot natural shallow depression. Initial design suggests that the area can be re-graded to accommodate the required water quality treatment volume as well as detention storage. Short landscaping walls might be necessary to maximize the available area. An overflow riser structure would be incorporated to control the allowable historic peak runoff rates. Discharged flows will then follow existing drainage patterns 147 Engineering Report-Aspen Water Plant Major Public Project Review SE Job#19003 S OPR IS E N G IN E ER IN G • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 7 | P a g e through the site towards the backwash pond where additional water quality treatment and detention volume will be provided. Drywell If the sand filter basin is determined to be infeasible for one reason or another an alternative option would be a dry well to provide the water quality treatment and detention volume. The location and general routing of runoff will remain the same as described above. The water quality treatment volume for a dry well is 150% more than the calculated water quality treatment volume and therefore the water quality treatment volume if a dry well is used will be approximately 234 cf. The drywell would have an overflow riser discharge pipe capable of detaining flows to historic levels. The approximate size and depth of the dry well is estimated to be a 6-ft diameter structure at 16-ft depth. Discharged flows will then follow existing drainage patterns through the site towards the backwash pond where additional water quality treatment and detention volume will be provided. The conceptual drainage mitigation design is illustrated on the attached civil plan set and will be evaluated further as the design progresses. F. Conclusion The proposed improvements being considered at the Water Plant Campus are all essential for current and further anticipated needs of the City’s Water Treatment Facility. Utility routing for the proposed building expansions is not anticipated since they are already being served. Conceptual utility service extension required for the proposed Maintenance Garage have been coordinated and schematically presented on the attached civil documents. Stormwater mitigation recommendations for the Maintenance Building have been conceptualized and outlined herein. It is understood that water quality treatment for the proposed addition to the West Plant and Administration Building will be required and that this analysis will be performed in support of any future Building Permit Application.

The City of Aspen Water Department is an Essential Public Facility.  It is a secure facility and receives very limited traffic.  Due to the secure  and compact nature of the water plant, the buildings located on the site are linked by internal sidewalks and driveways.  Due to the limited  number of external visitors, traffic calming is not required.  As a secure facility, there are no internal bicycle paths or meaningful  opportunities to make improvements  for bicycle traffic.  As suggested by Engineering staff, the Applicant will participate in two (2) minor  pedestrian improvements at the base of Doolittle Drive consisting of pedestrian improvments on the sidewalk and installation of an improved  hdilbhidh ii kTDM Explain the proposed shared shuttle service strategy in the space below. The use of hotel or other customer service vehicles to shuttle  employees can maximize the use of on‐site resources while reducing SOV trips. The successful project will creatively consider the use of  necessary business vehicles for shuttle purposes. For example, a health club with a guest shuttle could provide employee transfers to a  transit center or park and ride. Note, the provision of a hotel shuttle alone does not qualify for this measure. The Water Plant will improve the existing operation a shared shuttle service that will shuttle employees to meetings or other gatherings, as  necessary.  The Water Plant will pick employees up at the Bruch Creek Park and Ride Lot for shuttling to the Water Plant or other necessary  locations.   The City of Aspen provide bus passes to Water Plant employees.  Facilities will be maintained to support employees commuting  via bicycle including bike parking, locker rooms, and shower facilities.   Project Description In the space below provide a description of the proposed project. The City of Aspen Water Department is proposing the updating and expansion of several water plant facilities as part of their master planning  process for this Essential Public Facility.  Proposed development includes reservoir expansion, expansion of the existing administration  building, construction of a new maintenance and vehicle storage structure, new chlorination structure and tanks, and expansion of residual  dewatering bed.  No new employees are anticipated to be generated following the completion of the proposed development.   MMLOS Include any additional information that pertains to the MMLOS plan in the space provided below.  Click on the "Generate Narrative" Button to the right.  Respond to each of the prompts in the space provided.

The original City Water Plant Specially Planned Area (SPA) was approved in 1979. A series of amendments have occurred since then, with the most significant approving the development of affordable housing in 1996. The subject site is outside the Aspen Infill Area and underlying zoning is Public (PUB) with a Planned Development (PD) Overlay. Surrounding zone districts include City of Aspen Low-Density Residential (R-30), Conservation (C), Moderate-Density Residential (R-15/PD), Residential Multi-family (RMF) and Pitkin County Suburban Density Residential (R-30), Affordable Housing (AH), and Agricultural/Residential-10 acre (AR-10). The applicant is interested in updating and expanding several of the facilities as part of their master planning process for the water plant operations. This includes the development of a new maintenance and vehicle storage structure, expansion of the existing administration building, and potential expansion of the reservoir. An estimated 1,700 sq. ft. of additional structure is contemplated. As a governmental entity, the applicant is requesting review as a Major Public Project, pursuant to Chapter 26.500, Public Projects. Major Public Project review requires two public hearings, one at the Planning & Zoning Commission and one at City Council. The applicant shall respond to the review standards for Public Projects, as well as the other reviews listed below to ensure a robust consideration of the proposal and to meet one of the general review standards for Public Projects (26.500.070 (3)). The review criteria include all sections of the Land Use Code that would otherwise be applicable to the project in a standard review process, which are listed below. The following reviews will be combined into a two-step process, with a recommendation from the Planning and Zoning Commission and final decision at City Council. Planned Development The subject property currently contains a PD Overlay. For the PUB zone district, the dimensional requirements are established through the adoption of a Final PD Development Plan, pursuant to Chapter 26.445, Planned Development, which includes both Project Review and Detailed Review. The current allowances for the property were approved under Ordinance 18, Series of 1983 and are memorialized on the plat recorded at Book 16, Page 6, reception no. 259644. The proposed new development will likely require amending these allowances as well as the current and proposed development on the plat. The applicant will also be required to respond to the review standards in Sections 26.445.050 and 26.445.070 as part of the application. Growth Management The existing and proposed facilities qualify as essential public facilities. The development of essential public facilities requires Growth Management Review, pursuant to Sections 26.470.110.D. The Planning and Zoning Commission shall determine the number of employees generated by the proposed development (if any) pursuant to Section 26.470.050.C and make a recommendation to City Council. City Council will determine the level of 188 2 mitigation required. The applicant needs to provide responses to Section 26.470.080, General Requirements, in addition to the two sections already listed. Parking & Transportation The parking impact requirement for this property shall be reviewed and established through the Planned Development process. The current plat requires 11 parking spaces. Under the Traffic Impact Analysis (TIA) Guidelines, this project is considered Minor Development outside the roundabout (Between 501 and 2,199 sq. ft. of essential public facility outside the roundabout) and therefore required to submit a complete Level One TIA, pursuant to Section 26.515.030. A TIA requires that the trips associated with the new development be mitigated through MMLOS and TDM measures. The applicant is encouraged to discuss the best MMLOS mitigation measures with the Engineering Department prior to application submittal. All proposed TIA and parking impact mitigation shall be included in a complete Mobility Plan. More information on the TIA requirements can be found at https://www.cityofaspen.com/280/Documents-and-Permits. Environmentally Sensitive Area The property is located above the 8040 Greenline (8040 feet above mean sea level) and is therefore subject to 8040 Greenline review, pursuant to Section 26.435.030. Additional Requirements/Limitations This project will require Neighborhood Outreach, in addition to traditional public noticing requirements. The applicant must choose one or more of the forms of outreach as identified in Section 26.304.035.C. Due to the property adjacencies, Pitkin County will serve as a referral on this application. Pursuant to Chapter 26.600, redevelopment will require compliance with all adopted Impact Fees as well as the trash and recycle requirements from Municipal Code Section 12.10.
