Introduction This Engineering Report has been prepared in support of a Planned Development Project Review application for the redevelopment of the 300 Building which is located on Lot 3 of the Aspen Alps PUD. The information within this report presents our summary of preliminary engineering analysis and findings associated with serving the redeveloped building with utilities as well as providing stormwater mitigation per the requirements outlined within the City’s Urban Runoff Management Plan (URMP). The information outlined herein is conceptual with the understanding that more detailed information will become available as the design progresses. Preliminary civil drawings have been included with this report for illustrative support of this document. II. Background The 300 Building is one of eight buildings within the Aspen Alps Condominium Association which is located within the City of Aspen. A Consolidated PUD memorializing the existing conditions of the entire Association was recently approved by the City of Aspen. The entire complex encompasses approximately 7.4 acres and includes 73 condominium units, 3 affordable housing units, a parking structure and tennis court. The 300 Building was constructed in 1963 and currently consists of 7 multi-family units located within Lot 3 along with Buildings 400 & 500. Parcel 6 completely surrounds Parcel 3 and includes S. Alps Road. The Durant Mine Ditch passes through the southern portion of Lot 3. Segments of this ditch are piped as it passes through the subject property. An easement for this ditch was not identified on the Aspen Alps PUD Plat although this ditch likely carries a prescriptive easement given the length of time of uninterrupted flows through the subject property. A 20-ft wide fire hydrant water easement also falls on the subject parcel at the southeast corner. Lastly, a 20-ft wide sanitary sewer easement encroaches on the parcel at the southern part of the parcel. Lot 3 falls within the City’s “Red” mudflow zone. Development or redevelopment within this area, to include modifying existing grades or creating obstructions are required to perform a 100-year mudflow analysis to demonstrate that the proposed development will manage/mitigate any potential mudflow issues and not impact their property or neighboring properties. The applicant will run a quantitative analysis of debris flows, using the FLO-2D model and adjust the building design as necessary to accommodate the results of the modeling effort. The applicant will conduct such modeling as part of the detailed submission for this project so this issue can be accounted for at the same time as other issues identified in the Project Review stage are being addressed. In the meantime, the need for debris flow mitigation walls has been contemplated and potential locations for the walls have been reserved on the conceptual site plan and will be further developed upon the completion of the FLO-2D analysis.

Project Summary The proposed project is currently seeking approval for Planned Development Project Review, Growth Management (Expansion/Addition of Free Market Units within Multi-Family Project), Residential Design Standards Review and 8040 Greenline Review. The relevant approvals will facilitate the redevelopment of the 300 Building which will consist of removing the existing structure and replacing it with a multistory structure comprised of 10 multi-family units. This report outlines the utility, access and stormwater infrastructure required to support the proposed improvements. IV. Site Utilities This Section outlines our findings as it pertains to providing utility services to the proposed building. A conceptual utility plan has been included within the attached civil drawings for illustrative support. Additional details and routing will be provided during Planned Development Detailed Review with finalized design being submitting when a Building Permit Application is pursued. Water Service: The City of Aspen Water Department is the provider of potable water for the entire Aspen Alps Association. The 300, 400, 500, and 800 Buildings all obtain water service from a 6-inch Cast Iron Pipe (CIP) main located along S. Alps Road. Building 300 is currently served via a 2-inch tap off this existing 6-inch CIP water main. The location and orientation of the proposed 300 Building and associated site walls at the southwest corner of the building will result in less than optimal separation between the existing 6-inch CIP water main; therefore a portion of this existing water main will be replaced as part of the improvements to provide adequate separation between water main and structures. The relocation will include upsizing to an 8-inch ductile iron pipe (DIP) with adequate valve control to simplify future upgrades. This water main replacement will provide a minimum of 10-feet of clearance between water main and building/retaining walls. A new service line will be extended from this new segment of 8-inch water main and will be sized based on fire sprinkler demands. Future discussions and coordination with the Water Department is anticipated as the design progresses. Sanitary Sewer: Aspen Consolidated Sanitation District (ACSD) provides sanitary sewer service to this portion of the site via an 8-inch Vitrified Clay Pipe (VCP) that extends west from ACSD Manhole #UA-6 and up S. Alps for approximately 450-ft before terminating at ACSD Manhole UB-2. Two privately maintained independent service lines continue out of this manhole to provide service to three residential units outside the Aspen Alps association and for Aspen Alps Buildings 300-500 and 700. The sizes and material types of these private sewer lines are unknown. The shared sewer service for Buildings 300-500 is believed to run along the east side of the buildings and connects to the District’s main line located just south of the 300 Building. New sewer service will be extended from the existing shared sanitary sewer service line and therefore tapping the District’s main line is not currently being considered. It is our recommendation that this existing sewer service line be televised to verify alignment, material type, existing tap location and integrity of pipe to determine if any improvements are required. Lastly, a sand/oil interceptor will be provided for the proposed elevator drain.

The information provided within this section includes utility locates obtained during the improvement survey as well as discussions with the individual utility providers. Gas service is provided by Source Gas via a 1¼ -inch steel main that runs up S. Alps Road. The service line runs along the east side of the building and consists of 2-inch plastic pipe. According to Source Gas this line is owned by Aspen Alps. The existing gas mains and services are adequate given the existing load demands and Source Gas is not currently experiencing any issues in the area; however any redevelopment may require that any steel gas service lines be replaced with plastic pipes. As illustrated on the attached Conceptual Utility Plan a portion of the existing shared gas service line may need to be re-aligned to accommodate the proposed building. The gas service size will be based on load demands associated with the new building which will be determined prior to building permit application. All installation of gas services lines shall be performed in accordance with Source Gas rules and regulations. Electric service is provided by Holy Cross Energy via a three phase transformer (#3133 P5) located west of the building and across S. Alps Road. Emergency shutoffs and meters for Building 300 are provided adjacent to this transformer and service is routed through an electric vault located between the 300 Building and 400 Building. All service connections shall be installed per Holy Cross Energy’s specifications. Cable service is provided by Comcast. According to Comcast staff they recently performed a huge wiring upgrade last fall and there are new lock boxes for each of the 300, 400 and 500 Buildings. Service for the 300 Building will be re-established via one of these lock boxes or by installing a new pedestal adjacent to the new building. Service extensions and/or connections shall be installed per Comcast’s specifications. Telephone service is provided by Century Link via a pedestal located north of Building 500. This existing service line lies along the north side of the 300 Building. A new pedestal is proposed to be set on the existing line and a new service will be extended to the proposed building. All work associated with reestablishing telephone service to the new 300 Building shall be in accordance with Century Link’s rules and regulations. V. Access The primary access for the 300 Building is via S. Alps Road which is a private road that heads west off of Ute Avenue. This access has a minimum asphalt width of 18-ft with an average longitudinal slope of 8%. This road serves several other residences including Building 700 within the Aspen Alps. A fire truck turn-around has been provided at the west end of Building 500. The Fire District has indicated that if an 18-ft wide paved access is maintained and all buildings are equipped with a fire suppressant system that this road will be acceptable if any redevelopment is considered. Parking for the 300 Building is currently provided along the side of S. Alps Road immediately in front of the building. Currently there are no defined parking spots and therefore vehicles simply pull alongside the PD Project Review Engineering Report - Aspen Alps 300 Building March 10, 2016 502 Main Street • Suite A3 • Carbondale, CO 81623 • (970) 704-0311 • Fax (970) 704-0313 SOPRIS ENGINEERING • LLC civil consultants P a g e | 4 building. Additional shared parking is provided across from the 500 Building which requires guests and owners to walk along S. Alps Road to gain access to the 300 Building. The proposed improvements will improve this conditions by providing four parallel parking spaces adjacent to the proposed building. ADA access will be provided for at least one of the proposed parking areas. Access walks will be installed to provide direct access from the parking area to the west side of the building resulting in a much safer condition from what exists today. VI. Conceptual Drainage Analysis Introduction 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 to provide conceptual stormwater mitigation solutions, with a strong emphasis on water quality treatment, per the requirements outlined within the City’s URMP. This analysis will be expanded during the Planned Development Detailed Review process with final details, construction documents and drainage report being submitted with any future Building Permit Application. Existing Drainage Conditions The Aspen Alps 300 Building falls within Sub-Basin 15 of Drainage System 1 as described within the Surface Drainage Master Plan for the City of Aspen. This portion of the City’s storm system routes collected stormwater through the Glory Hole Pond as well as the water quality improvements located within the John Denver Sanctuary before ultimately discharging into the Roaring Fork River. The existing impervious areas surrounding the 300 Building has been estimated to be approximately 8,100+/- sf. The majority of this area consists of roof which directs runoff towards the east side of the building via gutters and downspouts and towards S. Alps Road which lies immediately west of the building. S. Alps Road falls within Lot 6 and is a designated Access and Utility Easement serving multiple buildings within the Aspen Alps Association as well as several single family residences. Offsite drainage is generally routed down this road and spills off at numerous locations. An existing inlet is located between the 300 and 400 Buildings. This inlet captures runoff flowing down S. Alps Road uphill of the 300 Building and redirects flows to the lower green space located on Lot 6. Runoff that does not get intercepted by this inlet as well as runoff immediately west of the 300 Building simply flows towards the 300 Building and gets re-directed to the south via several landscaping walls and curbs. Runoff passing through the area surrounding the 300 Building is then either infiltrated into the underlying soils as it is conveyed over the well vegetated area east of the building, directed into the Durant Mine Ditch or intercepted by an existing trench drain system located along the south side of 861 Ute Avenue. The Durant Mine Ditch and drainage improvements associated with 861 Ute Avenue are each connected to the City’s storm system that runs along the north side of Ute Avenue as described above as System 1. Drainage Mitigation Requirements and Variance Request This section outlines the stormwater requirements per the City’s Urban Runoff Management plan as well as a variance request pertaining to water quality treatment of the 400 and 500 Building for the Engineering Department’s consideration. PD Project Review Engineering Report - Aspen Alps 300 Building March 10, 2016 502 Main Street • Suite A3 • Carbondale, CO 81623 • (970) 704-0311 • Fax (970) 704-0313 SOPRIS ENGINEERING • LLC civil consultants P a g e | 5 The City of Aspen’s stormwater mitigation requirements are outlined within the Urban Runoff Management Plan, dated December 2014. This document states that any development that disturbs more than 1,000 square feet shall be classified as a “Major Design” project which requires water quality and detention volumes to be provided on-site; unless the site is directly connected to the City storm sewer system in which case stormwater detention is not required. The inclusive impervious areas that are subject to this requirement are dependent upon the extents of development or redevelopment. If the disturbed and/or added impervious area is less than 25% of the entire property then only the added impervious area and disturbed areas are subject to these requirements. If the disturbed and/or added impervious areas exceed 25% of the total property area then the entire property is subject to the stormwater requirements. The anticipated disturbance associated with the removal and replacement of the 300 Building is estimated to be approximately 17,000+/- square feet. This equates to approximately 40% of the entire lot area within Lot 3 and therefore technically triggers stormwater mitigation for all of Lot 3. The applicant will be requesting a variance for providing water quality treatment for the impervious areas associated with the 400 and 500 Buildings given the complexities associated with capturing, controlling and treating stormwater runoff from these already developed impervious areas. Any future redevelopment of these buildings will also be required to comply with the URMP requirements at which time water quality treatment mitigation can be implemented into the design. It should be noted however that each of the Buildings located within Lot 3 currently convey runoff over and through densely vegetated areas. This type of conveyance and disconnection of impervious areas does provide a level of water quality treatment. Conceptual Stormwater Mitigation Design The stormwater mitigation approach for this project will include the installation of curb & gutter along S. Alps Road, installation of a lateral storm sewer pipe that will connect to the City’s storm sewer system located along Ute Avenue and the implementation of strategically located Best Management Practices (BMPs) which will provide the required water quality treatment of stormwater runoff generated from the site improvements. This Section provides a brief discussion of the anticipated stormwater mitigation improvements that will be implemented in support of the proposed improvements with the understanding that final design of all drainage improvements will be provided at time of building permit application. A curb and gutter system is proposed along north and east side of S. Alps Road. This curb and gutter system is proposed between the north side of the building and will continue to Ute Avenue. Inlets will be provided at strategic locations along the proposed curb and gutter to maximize intercepting capacity of stormwater runoff. The inlets will be directly connected to a storm sewer pipe that will be extended up S. Alps Road and will ultimately connect to the City’s existing storm system that runs along Ute Avenue. This drainage collection system will assist with diverting stormwater runoff away from the proposed building, reduce runoff being conveyed through Lots 3 and 6 as well as minimize the amount of stormwater runoff being conveyed directly to the Durant Mine Ditch. Further analysis of this proposed system will be pursued as the project progresses towards Building Permit Application. In addition to the proposed drainage collection system the improvements associated with the proposed 300 Building will include the integration of water quality treatment BMPs. BMPs will likely include bioretention cells, green roofs, permeable pavers and grass buffers. A description of each of these potential BMPs are provided below: PD Project Review Engineering Report - Aspen Alps 300 Building March 10, 2016 502 Main Street • Suite A3 • Carbondale, CO 81623 • (970) 704-0311 • Fax (970) 704-0313 SOPRIS ENGINEERING • LLC civil consultants P a g e | 6 Green Roofs are structural roof components that filter, absorb and retain/detain stormwater runoff. The water quality benefits of green roofs include: biological uptake of stormwater runoff, evapotranspiration, moderates stormwater runoff temperatures, and reduces peak runoff rates and volumes by decreasing the amount of impervious area typically associated with traditional roof systems. Other advantages green roofs offer include reduced temperatures of rooftops, reduces air pollution, extends life of rooftops, provides heating and cooling effects for the building, presents an aesthetic improvement from a traditional rooftop and reduces noise pollution. The project is currently proposed approximately 2,000 sf of green roof which will offer a significant contribution to assisting with the overall reduction of impervious area currently associated with the 300 Building. Final locations and quantities of green roof areas will be explored as the design develops with the goal of reducing overall impervious areas as compared to what exists today. Permeable Pavers are comprised of a layer of concrete pavers separated by joints filled with small stones. Water enters the joints between solid concrete pavers and flows through an open graded base; i.e. crushed stone layers with no small or fine particles. The void spaces among the crushed stones store water and infiltrate it back into the soil sub-grade. Currently permeable pavers are contemplated for the parallel parking area located along the west side of the building and will assist with reducing impervious areas currently surrounding the existing 300 Building. The final design of the permeable pavers will be based on the criteria as outlined within Section 8.5.1.4 of the City’s URMP. The installation of all permeable pavers shall comply with the specifications provided by Interlocking Concrete Pavement Institute (ICPI). Grass Buffers are uniformly graded and densely vegetated areas that promote filtration, infiltration and settling to reduce runoff pollutants and when appropriately designed can provided the required water quality capture volume. The area located immediately east of the 300 Building does consist of well vegetated area and therefore offers the opportunity to integrate this type of water quality treatment mitigation. Further analysis of this concept will be pursued as the overall drainage mitigation plan develops with final design conforming with the requirements as outlined with the City’s URMP. Bio-retention Cells are depressed landscaping areas designed to capture and filter and/or infiltrate the water quality capture volume from a contributing drainage basin. The soil matrix and plantings remove pollutants through a variety of physical, biological and chemical treatment process. This type of BMP will likely provide the required water quality treatment of stormwater for areas that are not conveyed over or through permeable pavers, green roof and/or grass buffers. Overflow inlets will likely be required and can be connected to the proposed lateral storm pipe extended up S. Alps Road. Final sizing, location and design of any proposed bioretention cell will be determined prior to any future building permit application. Lastly, Per Section 3.5 of the PUD Agreement all future redevelopment projects within the Aspen Alps PUD shall be required to memorialize existing drainage patterns through drainage easements surrounding the proposed redevelopment area. The curb and gutter system described above will prevent upstream stormwater from passing through the southern portion of Lot 3 and contain runoff within S. Alps Road. Therefore, the resultant drainage easement associated with this redevelopment project will primarily fall within Lot 6 along S.

This proposed drainage easement is illustrated on the attached Civil Project Review Plans. VII. Summary & Conclusion The improvements proposed for the 300 Building are consistent with current underlying zoning and provide improvements to the amenities currently available at the subject property. Utility routing required to serve the redevelopment have been coordinated and schematically presented on the attached civil documents. Any and all required easements will be provided to the appropriate utility providers at the time of final plat. In regards to stormwater mitigation, the reduction in effective impervious areas and incorporating water quality treatment facilities and storm sewer improvements will reduce impacts to the surrounding properties while improving the quality of stormwater runoff exiting the site. Furthermore, the redevelopment includes the construction of four parallel parking stalls immediately west of the proposed building which will vastly improve direct access to the building and reduce pedestrian traffic on S. Alps Road. In conclusion, no adverse impacts will result from the proposed redevelopment of the 300 Building. Additional information will be provided during the Planned Development Detailed Review phase with final site grading, utility routing, drainage report and proposed stormwater mitigation infrastructure being provided at time of any future building permit application.

Project Description In the space below provide a description of the proposed project. The project consists of removing and replacing the 300 Building located within the Aspen Alps PUD. The new building will replace the existing 7 units and add 3 additional free market units as well as provide four parallel parking stalls with ADA access to the building. MMLOS In the space provided desicribe what new landscaping is proposed and how the proposed landscaping plan enhances the pedestrian experience. This measure is only applicable to large scale projects and requires more extensive landscaping then a few plantings or lawn area. The project shall establish extensive landscaping which significantly benefits the site and improves the pedestrian comfort and experience. A detailed landscaping plan has not been developed however it is anticipated that landscaping improvements will include trees, appropriate ground cover to help screen the west side of the building from the road as well as tiered landscaping walls along the north and south sides of the building. Describe the enhanced pedestrian access point(s). This measure is to improve pedestrian access to the site from the ROW. It includes adding additional access points which prevent pedestrians and bicyclists from crossing a street, improvements to the project's ADA ramps in the ROW, and improvements to existing access points. This particular project is unique in that it is not located in the downtown core, is not located adjacent to any major intersections, is connected to a private road and employees typically report to the 200 Building; however the goal of implementing MMLOS measures is to enhance the pedestrian access from the site to the City's ROW. Therefore, the most logical improvement will be to provide a landscaped trail linking the new building with the existing, and improved, trail along the east side of the site. This trail currently provides access to Ute Avenue's pedestrian corridor. This trail connection will provide a safe pedestrian route from the site to the City's ROW and will not require crossing any streets or travel along S. Alps Road to Ute Avenue. The alignment and treatment of this proposed path is still under design. In addition, it is likely that this trail connection may not always be available during winter months because of required maintenance associated with keeping the route open. This MMLOS concept was presented and found to be acceptable to City Engineering Staff. Explain any additional minor improvements which benefit the pedestrian experience and have been agreed upon with City of Aspen staff. Currently there are no sidewalks or formal parking provided along S. Alps Road and adjacent to the 300 Building which forces residences and guests to park across from the 500 Building and utilize S. Alps Road as the primary route to the 300 Building. The proposed improvements include the addition of four parallel parking spaces along the west side of the building which will allow residences and/or guests to park in dedicated parking stalls adjacent to the building. This will eliminate need to park across from the 500 Building and use S. Alps Road as the primary means of access to the building. Furthermore, access walks are proposed along the west side of the building which will provide direct ADA access to the building thereby improving the pedestrian experience. Include any additional information that pertains to the MMLOS plan in the space provided below. The goal is to encourage guests and employees to bike from the proposed building to downtown amenities and therefore bike racks will be provided onsite. Furthermore, the redevelopment of the 300 Building also contemplates providing a formal path connection to the stairwell located along the south side of the 400 Building which will benefit the residents/guests of that building. TDM Provide details for the proposed bike share program participation. Bike sharing provides access to a fleet of bicycles for short trips, thus reducing SOV travel. The successful project will provide memberships to the existing WE-cycle program. Include details on how many WE-cycle memberships will be purchased and whether these will be made available to guests, employees, or both. In an attempt to further reduce the number of SOVs traveling to the site Aspen Alps managment has suggested participating in the WE-Cycle program. The applicant is currently looking into purchasing approximately 10 season passes for employees to use to run errands around town. The applicant is also looking into purchasing 500 (2) 1/2 hour trips that could be used by guests. Guests will be made aware of this service at time of check-in. The number of season passes and (2) 1/2 hour trips will be reviewed and usage adjustments will be made accordingly. Include the following on a site plan. Clearly call out and label each measure. Attach the site plan to the TIA submittal. Slopes of parallel parking and access to the Building Enhanced Pedestrian Access Point Explain the proposed self-funded emergency ride home strategy below. Emergency Ride Home programs reduce barriers associated with alternative commute modes, thus reducing SOV trips. The successful project will develop and fund a program to provide commuters who carpool, vanpool, bike, walk or take transit to work with a reliable and free ride home - usually in a taxi or rental car when unexpected emergencies arise. The use of the TOP program's Emergency Ride Home service is not applicable for mitigation purposes. The Aspen Alps will provide either a shuttle ride in one of their vehicles or a taxi ride down valley depending on the circumstances and more importantly the needs of the employee and their family. Include any additional information that pertains to the TDM plan in the space provided below. Aspen Alps is very interested in reducing single occupancy vehicles to and from the property. In fact, management currently offers subsidized bus passes for maintenance and housekeeping staff who commute from outside the Aspen area. This currently makes up about 28 of the total 46 full time employees. Also, Aspen Alps provides 3 onsite employee housing units within the 700 Building. Furthermore, maintenance staff currently travels the property by bicycle whenever appropriate (such as when no tools are necessary for their task). These strategies certainly reduce the number of SOVs to & from the site everyday. MMLOS Site Plan Requirements Pedestrian Directness Factor Additional Minor Pedestrian Improvement Enforcement and Financing Provide an overview of the Enforcement and Financing plan for the proposed transportation mitigation measures. All MMLOS and TDM measures will be monitored and paid for by Aspen Alps Condominium Association. The Aspen Alps management will make a good faith effort to survey the homeowners, guests, tennants and employees participating in the proposed TDM measures. The purpose of this required survey is to assess whether the measures are being maintained and if participation levels meet critical mass. The results of the survey along with an associated monitoring report shall be submitted to the CIty of Aspen's Transportation Department at least annually for the first three years. The report shall include the following information: 1) Status of all exisitng TDM programs, 2) Status of all recommended TDM programs from prior monitoring reports (if applicable), 3) Data collection methodology, 4) Survey results, 5) Evaluation of performance compared to TDM/MMLOS plan, 6) Conclusion of whether compliance is met 7) Next steps (if needed) ie. future modifications and enhancements of TDM program, including timeframe of implementation. Scheduling and Implementation Responsibility of Mitigation Measures Provide an overview of the scheduling and implementation responsibility for the proposed transportation mitigation measures. All MMLOS and TDM measures will be completed during the construction phase of the project. They will be part of the plan set submitted to the City of Aspen Building Department for Engineering review. The applicant understands that issuance of a certificate of occupancy is contingent upon satisfactory installation of MMLOS improvements and implementation of TDM measures, as reviewed and approved by the Engineering Department. Monitoring and Reporting Provide a monitoring and reporting plan. Refer to page 17 in the Transportation Analysis Guidelines for a list of monitoring plan requirements. Components of a Monitoring and Reporting Plan should include (1) Assessment of compliance with guidelines, (2) Results and effectiveness of implemented measures, (3) Identification of additional strategies, and (4) Surveys and other supporting data.
