The MDR was prepared in support of the entire Phase II Burlingame Affordable Housing Project that included 161 multi-family affordable housing units divided amongst 15 buildings as well as four single family lots. Buildings 1-7, portions of Paepcke Road, site utilities and drainage infrastructure have been completed and the remaining buildings (Buildings 8-15), utilities, grading and drainage improvements are currently being proposed under the Phase III scope of work. Some architectural and grading revisions have occurred during the design of the Phase III improvements as compared to what was considered within the Phase II approval documents. Accordingly, these drainage and grading revisions have been qualified and, in some cases, revised to adhere to the intent of the MDR. This letter summarizes these various revisions and provides supplemental documentation in support of our analysis and confirmation that the Phase III improvements will not have any adverse impacts to the surrounding area and comply with the intent of the MDR. Master Drainage Report (MDR) Background: The MDR prepared in support of the Phase II improvements, which included what is being considered with the Phase III improvements, were documented and approved under the Phase II 100% Implementation Documents. The MDR was broken into three separate volumes based on the resultant post development drainage basins which included Harmony Pond, Pond 2 and North drainage basins. Each of these volumes provided extensive analysis relative to onsite and offsite peak stormwater runoff, collection and conveyance of developed surface runoff, as well as water quality treatment of the increased proposed impervious areas associated within each of the specific drainage basins. All improvements within the North Drainage Basin (identified within the MDR with a “C” suffix) were completed under the Phase II improvements. In addition, all improvements within Pond 2 Drainage Basin (identified within the MDR with an “A” suffix) have also been completed with the exception of the northern portion of Building 8, carports P8 and P9 and approximately 500-ft of Paepcke Road. All remaining improvements considered within the currently proposed Phase III improvements fall within the Harmony Pond Drainage Basin (identified within the MDR with a “B” suffix). The previous nomenclature that was used within the MDR for drainage basins, rain gardens and various other design points were adopted from the MDR. This nomenclature identified receiving design points and rain gardens by their tributary drainage basins. For example, Rain Garden 4B provides water quality treatment for sub-basin 4B which falls within the Harmony Pond Drainage Basin since it carries the “B” suffix. The remaining portions of this letter are specific to outlining variations in drainage basins, post development peak runoff rates, significant adjustments to rain gardens and other drainage infrastructure revisions specific to the Phase III improvements. It should also be noted that the stormwater model has been updated to reflect the remaining proposed improvements located within drainage basins Pond 2 and 12/28/2020 Burlingame Phase III Drainage Letter S OPRIS E NGINEERING • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 Page 2 Harmony Pond. Input and output data of the updated 5-year and 100-year models are provided as an attachment to this letter. Post Drainage/Sub-Basin Descriptions: The Phase II post development drainage basins were established within the MDR to determine peak runoff rates for the Phase II improvements as well as water quality treatment volumes. The basins were further subdivided to size onsite drainage infrastructure such as inlets, rain gardens and surface swales. The subbasins associated with the Phase III improvements were updated as necessary based on the Phase III architectural and minor grading revisions but for the most part remained consistent with what was considered under the Phase II MDR. The only significant revisions to post development subbasin revisions from the MDR are as follows: Basin 14B1 was further subdivided to include a new basin 14B1.1 in order to determine the tributary runoff to a proposed water quality rain garden located in the front yard of Building 13. Further discussion of the proposed rain garden can be found in the Water Quality section of this letter. Basin 27B1 was further subdivided to include a new basin 27B1.1 in order to determine the tributary runoff to a proposed water quality rain garden and stormwater infrastructure located at the base of the hillside west of Paepcke Road, above parking area P12. This additional basin was created as a result of grading modifications required to reduce unnecessary import of material along the backside of parking areas P12 & P13. As a result, a new rain garden is proposed to collect surface runoff from offsite basin 27B1.1 as well as an additional inlet and extended storm pipe. Further discussion of the proposed rain garden and stormwater infrastructure is outlined within the W ater Quality and Storm Sewer Sections of this letter. A visual representation of the Phase III sub basins can be found on Sheet C7.01 of the permit plans included as an attachment to this letter. The original post development sub basins delineated with the MDR are additionally depicted, faded back, for reference. Interim Drainage Basins: The proposed Single Family Home Lots 3 & 4, previously referred to as RO5 and RO6, which are located east of Building 15 are not part of the proposed Phase III improvements, and will be constructed at a later date. The assumptions used in the MDR were adopted for ultimate buildout conditions however Phase III improvements include interim overlot grading on Lot 3 and Lot 4 to direct surface runoff to existing or proposed stormwater infrastructure. This results in an interim grading and drainage condition where surface runoff generated from these lots will be directed toward Phase III improvements with final drainage and water quality improvements specific to these lots being constructed at a later date. Accordingly the tributary runoff and resulting water quality capture volume to the Phase III improvements were analyzed for both the interim and full buildout conditions to determine appropriate sizing parameters were being met. In summary, our analysis determined that the full buildout condition was more conservative in all cases and therefore all rain gardens to be constructed with the Phase III improvements are sized based on the full ultimate buildout condition of Lots 3 & 4. Hydrologic/Hydraulic Methods and Assumptions: The Phase II Storm and Sanitary Sewer Analysis (SSA) model was updated to reflect the various grading and drainage revisions associated with the Phase III improvements. The model was also updated to reflect adjusted recommended runoff coefficients per UDFCD as well as revised NOAA rainfall data. This information was used to update estimated 5 and 100-year peak runoff rates. A summary of the resultant post development peak flows for all sub-basins analyzed with the Phase III improvements have been summarized within Tables 1a and 1b below for drainage basins Pond 2 and Harmony Pond, respectively. Also, these tables compare the original peak runoff volumes for the individual design basins as calculated 12/28/2020 Burlingame Phase III Drainage Letter S OPRIS E NGINEERING • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 Page 3 with the MDR compared to the new estimated peak runoff values from the minor modifications necessitated by the Phase III improvements and adjusted runoff coefficients and rainfall data. Table 1a-Pond 2 Sub-Basin Peak Runoff Summary Table 1b-Harmony Pond Sub-Basin Peak Runoff Summary 12/28/2020 Burlingame Phase III Drainage Letter December 11, 2020 S OPRIS E NGINEERING • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 Page 4 Storm Sewer sizing performed in the MDR was achieved by using StormNET Software (now known as Storm and Sanitary Analysis). As mentioned above, the Phase II SSA models were updated to reflect the proposed modifications within the Phase III improvements. As previously mentioned a new rain garden (RG 27B1) and associated outlet pipe is proposed with the Phase III improvements as depicted on sheet C6.02 of the permit drawings. The updated SSA analysis determined that the existing 15” RCP pipe that was installed under the Phase II improvements is undersized to handle the additional tributary runoff that was not considered under the MDR. Accordingly, the portion of the 15” RCP storm sewer segment beneath Paepcke Road will be upgraded to an 18” RCP storm pipe and then extended to serve the proposed rain garden. Supporting data from the SSA model can be found as an attachment to this letter. All other storm sewer results are consistent with the Phase II MDR. Culverts were proposed at several locations within the MDR. All locations previously studied in the MDR were adopted in the Phase III SSA model, and remain unchanged. An additional culvert (Culvert 31B2) is proposed under the Phase III scope of work to direct runoff under the proposed trail that passes through Park 3. Although this culvert was necessary under the original Phase II design it was not identified within the plans or included in the stormwater analysis and therefore the models were updated to reflect this additional culvert. Supporting data can be found within the appendix of this letter and the resultant culvert size is identified on the plan set. Water Quality: During the development of the Phase III design documents, some modifications were made to the proposed building architecture, roof lines, site access walks and associated site grading. Accordingly, slight adjustments were made to the proposed water quality treatment improvements to ensure the required water quality capture volumes meet the requirements of the City’s Urban Runoff Management Plan. A summary of the updated water quality design basins can be found in Table 2 below and depicted on Sheet C7.01 of the permit drawings. Rain Gardens are integrated throughout the development to provide water quality treatment for impervious roof and pavement proposed with the Phase III improvements. The onsite drainage sub- basins originally delineated in the MDR have been verified and modified slightly where necessary to meet the updated building architecture and associated grading. The proposed rain gardens were additionally updated in the SSA model to verify the individual adequate water quality treatment volume is provided for the respective tributary area. Revisions to the proposed rain gardens worth noting include the following: RG-5B was located northeast of Building 14 and fell within Harmony Pond Drainage Basin. Due to previously installed utility infrastructure and the need to extend a water service through this area this rain garden was eliminated from the design. As a result runoff from Basin 5B will be conveyed to Rain Garden 4B via overland flow, shallow swale and a series of drain chases. Accordingly RG 4B was revised to account for the additional water quality treatment volume. RG-14B1.1 is located in the front yard of Building 13, above the proposed boulder wall adjacent to Paepcke Road. RG-14B1.1 collects roof drainage and surface runoff from a portion of Building A13. Filtered water is collected in an underdrain and routed to the storm sewer system within Paepcke Road. RG-14B1.1 is additionally outfitted with an overflow inlet to safely convey larger storm events above the water quality capture volume. 12/28/2020 Burlingame Phase III Drainage Letter S OPRIS E NGINEERING • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 Page 5 RG-27B1 is located just west of parking area P12 and falls within Harmony Pond Drainage Basin. This proposed rain garden was added to the overall water quality treatment design for the Phase III improvements and was not originally conceptualized within the MDR. Grading at the base of the hillside west of parking area P12 was altered from the Master Drainage Study to reduce import fill quantities for the development. As a result, a new rain garden RG-27B1 is proposed to collect surface runoff from offsite basin 27B1.1 and to provide water quality treatment for the impervious roof areas associated with parking area P12. Runoff volumes in excess of the rain garden’s treatment capacity are collected within an overflow inlet and discharges to a proposed 18” RCP storm sewer that will connect to the existing storm system that runs along Paepcke Road. Due to the additional flow directed to this storm system, our analysis indicates a short section of existing 15” RCP will need to be replaced with an 18” RCP as reflected on the civil plan set and attached exhibit. RG-2A was located west of Building 9 and fell within Pond 2 Drainage Basin. This rain garden was eliminated from the design due to revisions to Building 9’s roof lines which reduced the tributary impervious area being conveyed to this water quality treatment area. As a result it was determined that the water quality volume from this small tributary area could be provided within the next downstream rain garden (4A). RG 6A-8A were constructed with the Phase II improvements but were determined to be undersized. Therefore some modifications to these rain gardens is being proposed with the Phase III improvements as summarized below in Table 2 and the civil plan set. Tables 2a and 2b summarize the rain garden design parameters for the proposed Phase III improvements for Drainage Basins Pond 2 and Harmony Pond, respectively. It should be noted that rain gardens identified with an asterisk (*) will require an underdrain system with an orifice plate given their proximity to buildings and retaining walls. Although the underlying soils don’t suggest the need for underdrain systems elsewhere through the site orifice calculations were performed for the remaining rain gardens in case they are determined to be necessary once further geotechnical evaluations are performed during construction. Table 2a-Pond 2 Revised Rain Garden Design Summary 12/28/2020 Burlingame Phase III Drainage Letter S OPRIS E NGINEERING • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 Page 6 Table 2b-Harmony Pond Revised Rain Garden Design Summary Water Quality Dry Well (DW) is proposed at the northwest corner of Paepcke Road/Forge Road intersection (DW-25B). This dry well provides water quality treatment for portions of Harmony Rd and Mining Stock Parkway. This water quality dry well was proposed under the Phase II improvements and analyzed within the MDR but given the various site grading revisions it was re- qualified under the design of Phase III improvements. In summary, the rim elevation was adjusted slightly and the required water quality treatment volume was confirmed. It should be noted that an additional dry well is proposed (DW-21B) which is located between parking area P11 and Building E15. This drywell is not required for water quality treatment mitigation but rather allows for the up gradient storm system to be lower than the outlet to ensure adequate cover of the storm system is provided. This is consistent with the approach taken under the design of Phase II improvements and outlined within the MDR. Permeable Pavers were designed with the MDR to promote water quality treatment and infiltration of stormwater runoff within parallel parking areas along Paepcke Road. The tributary runoff to the respective permeable paver zones remains unchanged from the MDR and the respective basin imperviousness has been adopted with the Phase III SSA model update. 12/28/2020 Burlingame Phase III Drainage Letter S OPRIS E NGINEERING • LLC civil consultants 502 Main Street Suite A3 Carbondale Colorado 81623 (970)704-0311 Fax:(970)704-0313 Page 7 Harmony Pond Design Point corresponds with the outfall to Harmony Pond which is an existing pond that provides irrigation storage and detention for Burlingame Phase II improvements. The as-built conditions of this pond and associated outfall structure were analyzed in the MDR (Vol. 1) to verify the capacity of the facility for the ultimate buildout of the Phase II improvements. Table 3 summarizes the design release rates associated with the anticipated peak runoff that is to be conveyed through Harmony Pond and its outfall structure. Allowable release rates and post development release rates outlined within the original Phase II MDR (Vol 1) are provided within Table 3 along with the updated post development release rates based on the revised Phase III improvements. Table 3: Harmony Pond Peak Inflow/Outflow Summary The slight increase in peak inflow and discharge rate for the proposed improvements, associated with the 100-year storm event, can be attributed to the increase in peak rainfall intensity for a 5-minute minimum time of concentration within the NOAA Atlas 14 rainfall data. Regardless, the anticipated peak discharge from Harmony Pond is well below the historic rates. Conclusion: All aspects of this design were prepared in accordance the City of Aspen URMP. The post development drainage basins were also delineated and corresponding 5- and 100-year peak flow rates have been estimated. The proposed stormwater infrastructure has been determined to be adequate for the 100-year storm event. Harmony Pond and its outfall structure was also analyzed to ensure the existing facility has adequate capacity. The proposed Phase III improvements are in general conformance with the Phase II Master Drainage Report and will have no negative impacts to adjacent downstream users.
