GENERAL LOCATION AND DESCRIPTION SITE LOCATION The Ridgewood Hills Fifth Filing (hereafter referred to as "the site" or "project site") is a 34.81-acre project site located in the City of Fort Collins, Larimer County, Colorado. The project site is bound to the north by Triangle Drive; to the east by South College Avenue (US HWY 287); and to the south by undeveloped land. The west property boundary is adjacent to parkland and open space to the north and portions of Ridgewood Hills PUD 3�d Filing and Ridgewood Hills Fourth Filing to the south. Ridgewood Hills Fourth Filing is currently under construction. The project site is located on four separate parcels: - Parcel 1 is described as Tract A of the Shenandoah PUD Filing One; Parcel 2 is described as a portion of the East'/2 of the Southeast'/4 of Section 14, Township 6 North, Range 69 West of the 6th Prime Meridian, in Larimer County Colorado; Parcel 3 is described as a portion of the East'/2 of the Southeast'/4 of Section 14, Township 6 North, Range 68 West of the 6th Prime Meridian, in Larimer County Colorado; Parcel 4 is described as a portion of the Tract C of the Shenandoah P.U.D. DESCRIPTION OF PROPERTY The 34.81-acre project site is currently undeveloped and consists of open fallow land. Vegetation on the project site consists of mostly invasive weeds and grasses. The project site currently drains from west to east at slopes ranging from 2% to 50%. The average slopes are between 5% and 10% and the steeper slopes up to 50% occur adjacent to the east property boundary at South College Avenue. Refer to sheets C1.0 and C1.1 — Existing Conditions & Demo Plan in Appendix E. There are several existing delineated natural areas and buffer zones present on the site, as defined by Section 3.4.1 of the City of Fort Collins Land Use Code. There are four wetland areas delineated on the project site — two at the northeast corner of the site, near the intersection of Triangle Drive and South College Avenue and two at the southwest corner of the site (i.e., developed basin WT3). A section of the North Loudon Ditch bisects the project site, which is also classified as a natural area. Proposed development that disturbs these areas and their buffer zones will require mitigation (i.e., developed basin WT2) as required by the Land Use Code. The Robert Benson Lake Inlet Swale (Inlet Swale) bisects the north quarter of the site and conveys off- site drainage (i.e., existing 42" RCP) from the neighborhood to the north of Triangle Drive (Shenandoah PUD Filing One, refer to Appendix D for Northern Engineering storm sewer plan and profile). Diverted flows owned by City of Fort Collins Natural Areas Department and emergency overflow flows (i.e., ±2.0 cfs) from North Louden Ditch also are conveyed through the inlet swale. The Inlet Swale drains to an existing 48" RCP under College Avenue that outlets to Robert Benson Lake to the east. Undetained off-site drainage areas, immediately to the west of the project site, were delineated as part of the Ridgewood Hills PUD 3�d Filing (i.e., OS-4 (Tract N), 821, 917 and 918 per Nolte Associates). These off-site basins were developed as part of the Ridgewood Hills Fourth Filing (Engineer: Owen Consulting Group, Inc.). A small amount of runoff from portions of Ridgewood Hills Fourth Filing basins N-7 and SB- 14 will flow undetained onto the project site and will be routed through as part of the project development. It was the intent of the Ridgewood Hills PUD 3�d Filing drainage design that the majority of the developed runoff from basins OS-4, 821, 917 and 918 was to be captured with Ridgewood Hills Fourth Filing Galloway & Company, Inc. Page 4 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 improvements in Avondale Road and then conveyed to existing storm drain infrastructure in Ridgewood Hills PUD 3�d Filing. However, the Ridgewood Hills Fourth Filing design and as-built condition differed. In a memo dated November 30th, 2020, Larry Owen (Owen Consulting Group, Inc.), estimated no runoff from the 2-year minor storm event and 17.8 cfs from the 100-year major storm event entering the proposed Ridgewood Hills Fifth Filing project site as bypass flows from DP11. We understand there is 10' Type R curb inlet at DP B11. An exhibit in Appendix D tracks the general flow path of this runoff through the proposed Ridgewood Hills Fifth Filing project site. As the runoff enters the project along the south curb line of Avondale Road, it should continue flowing past Field View Drive and rejoin the south curb line of Avondale Road. Some runoff may split and flow into Field View Drive. This runoff will follow the east curb line and drain to Design Point (DP) C10. The available ponding depth at DP C10 is limited to ±0.42' and overtopping flows drain to DP C14/C15. This is the same design point that bypass flows could drain to following the south curb line of Avondale Road toward Torreys Street. Currently runoff in basin C14 drains southeast in Avondale Road and then southwest into Torreys Street. The minor event flows in basin C14 and the majority of major storm event flows should wrap around the corner and drain to the proposed inlets at DPs C14/C15. The T� to DPs C14/C15 is ±20.5 minutes. This is based on the routed T� to DP 917 (i.e., ±15.5 minutes) as shown in the Ridgewood Hills PUD 3�d Filing plus the T� in basin C14 (i.e., ±5.0 minutes). Looking at the T�, the local peak should have passed by the time off-site flows arrive. Since time of concentration values presented in the above-mentioned memo were not calculated using CoFC methods, we used time of concentration values presented in the Ridgewood Hills PUD 3�d Filing drainage report. Local flooding at DPs C14/C15/C16 should not impact local structures. Once the ponding depth is greater than ±0.60-foot, water will spill into Avondale Road and flow southeast. A copy of the drainage maps from the Ridgewood Hills PUD 3�d Filing and Ridgewood Hills Fourth Filing are included in Appendix D. Proposed improvements with the project site include the construction of multi-family, single-family attached and single-family detached residential units with associated roads, drives and utilities infrastructure. On-site detention of the project site will be divided amongst three separate constructed ponds that will release at 0.2 cfs/ac as mandated by the Fossil Creek Drainage Basin Master Plan. Stormwater quality And Low Impact Development (LID) features will be constructed to satisfy the City of Fort Collins Low Impact Development (LID) and Natural Areas mitigation requirements. According to the Natural Resources Conservation Service (NRCS) Web Soil Survey, the project site consists of a mix of soil types and Hydrologic Soil Groups (HSGs)including: - Fort Collins Loam, HSG `C', 41.9% of total project area - Heldt Clay Loam, HSGs `C', 12.2% - Longmont Clay, HSGs `D', 18.2% - Renohill Clay Loam, HSGs `D', 1.0% - Santana Loam, HSGs 'B', 9.7% - Wiley Silt Loam, HSGs `B', 17.0% Galloway & Company, Inc. Page 5 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 The predominant on-site HSG is `C'. Group C soils are described as having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Refer to Appendix A, for the Web Soil Survey and soils information. A geotechnical report was prepared by CTL Thompson, Incorporated in August 2019 for the project site. The report included site-specific borings for the project site. Twelve exploratory borings were performed across the project site and discovered that subsurface conditions generally consisted of sandy clay over weathered and competent bedrock. Bedrock consisted primarily of sandy claystone. Groundwater was observed at depths of approximately 0.5' to 23.5' below the ground surface. Areas that experience shallow groundwater under the existing condition are located primarily at the south end of the site, at the location of the existing wetlands. The shallow groundwater present on the site contributes to the existing wetlands and should help reestablish wetlands within areas proposed as mitigation for those to be disturbed (i.e., developed basin WT2). Proposed site improvements, including the detention ponds, are determined to be above modeled groundwater levels as outlined in the geotechnical report. Galloway & Company, Inc.

DRAINAGE BASINS AND SUB-BASINS MAJOR BASIN DESCRIPTION The project site is enveloped entirely within the Fossil Creek drainage basin, as delineated by the City of Fort Collins Drainage Basin Master Plan. The Drainage Basin Master Plan was approved by City Council in June of 2004 and describes the flooding history of the specified basins and offers guidance for new development within the basins. On-site detention is required to detain the 100-year developed storm event and release it at the 2-year historic release rate. In the Fossil Creek drainage basin, the 2-year historic release rate is 0.2 cfs/acre. The project site is shown on FEMA Map Number 08069C1200F. The floodplain map indicates the project exists within Zone X- Area of Minimal Flood Hazard and is, therefore, not impacted by an existing floodplain/floodway. Refer to Appendix A for a Firmette of the Flood Plain Hazard Map. SUB-BASIN DESCRIPTION The sub-basin development included herein is intentionally general with respect to the on-site developed drainage basins. More detail is provided in section IV. DRAINAGE FACILITY DESIGN. Refer to Appendix E for sheets C12.0 and C12.1, Drainage Plan. Detailed information does follow for the off-site basins located west of the project site. OFF-SITE Ridgewood Hills PUD 3�d Filing and Ridgewood Hills Fourth Filing Off-Site Basins: Several off-site basins exist along the west property boundary and were originally delineated with the Ridgewood Hills PUD 3�d Filing development and consist of portions of single-family residential lots, paved roadway associated with the Avondale Road extension to the east and undeveloped fallow land (i.e., basins OS-4, 821, 917 and 918). Under current conditions, runoff from these basins sheet flows directly onto the project site. Upon completion of the Ridgewood Hills Fourth Filing, the Avondale Road extension and the majority of the developed areas are captured and routed to existing Pond #2 constructed with Ridgewood Hills PUD 3�d Filing. A small portion of Ridgewood Hills Fourth Filing along the west property boundary slopes sharply to the project site (i.e., portions of basins N-7 and S614) and will not be captured and directed to the existing detention pond. These areas will remain undeveloped and will primarily consist of lawn and landscaped areas. The basins will be diverted at the property boundary via a system of swales and curb and gutter and directed into the Ridgewood Hills Fifth Filing storm drain system. Shenandoah PUD Filing One Off-Site Basins: The basins consist of a developed neighborhood subdivision to the north of Triangle Drive. These basins were delineated with the Shenandoah PUD Filing One development and consist of portions of single-family residential lots, paved roadways, sidewalk, landscape and other hardscape. These basins are captured via a system of underground storm drain that discharges on the project site into the Inlet Swale. The existing 42" RCP underground storm drain from the Shenandoah PUD Filing One (refer to Appendix D for a copy of the approved storm drain plan and profile) will be re-routed through the project site where it will discharge into the Inlet Swale and eventually into the 48" RCP culvert under South College Avenue that discharges into Robert Benson Lake. Galloway & Company, Inc. Page 7 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 Louden Irrigation Ditch: A portion of the Louden Irrigation Ditch bisects the existing project site. The ditch enters the site at the south property boundary, where it meanders across the property, generally from south to north. The ditch enters a culvert near the north property line at Triangle Drive where it passes under the street and resumes open-channel flow north of Triangle Drive. The Ridgewood Hills Fifth Filing project requires the relocation of the ditch. The ditch will still enter the site at the south property boundary where it will continue in its current configuration to a point north and west of the large existing wetland at the southwest corner of the site. There, the ditch will be intercepted and conveyed via an underground pipe system to the northeast. The ditch then resumes open-channel flow as it crosses onto a neighboring property to the east. It is then intercepted again with an underground pipe system as it re-enters the site further north and continues toward the culvert at Triangle Drive via a combined open channel and underground piping system. A portion of the open-channel conveyance north of Castle View Drive will be within the existing ditch before being intercepted again by an underground piping system directed to the culvert at Triangle Drive. The ditch continues its current conveyance pattern north of the Triangle Drive culvert. ON-SITE A-Basins: These basins are compositionally similar and comprised of the north and east portion of the project site, east of Strasburg Drive, Strasburg Drive, and portions of Castle View Drive, west of Strasburg Drive. The composition of the development consists of the building roof areas from the multifamily buildings and clubhouse building, asphalt, curb and gutter, sidewalks, landscaping and outdoor amenity areas. These basins are intended to be captured via the on-site storm drain system and routed to Pond A at the northeast corner of the site, near the intersections of South College Avenue and Triangle Drive. The outlet flows from Pond A will be routed to the Inlet Swale and eventually into the existing 48" RCP storm drain that passes under South College Avenue and discharges into Robert Benson Lake. B-Basins: These basins are compositionally similar and are comprised of a portion of the proposed Castle View Drive right-of-way; a portion of the Field View Drive right-of-way, north of Avondale Road; a portion of the east right-of-way of the Avondale Road extension, north of Field View Drive; and a portion of the detached single-family buildings to the east of Pyramid Vista Way. The composition of development consists of paved roadways and sidewalks, paved parking areas, roof areas from detached single-family homes, landscaped areas and other hardscape. These basins are intended to be captured via the curb and gutter, overland flow and on-site storm drain system and routed to Pond B to the southwest of the intersection of Strasburg Drive and Castle View Drive. The outlet flows from Pond B will be routed to the Inlet Swale via a storm drain system and eventually into the existing 48" RCP storm drain that passes under College Avenue and discharges into Robert Benson Lake. C-Basins: These basins are compositionally similar and are comprised of the Avondale Road right-of- way extension, south of Field View Drive; the detached single-family buildings to the north and south of Field View Drive, east of Avondale Road; the proposed Maroon Vista Way, Pyramid Vista Way and Grand Way; and the attached single-family buildings along Torreys Street and Field View Drive. The composition of development consists of paved roadways and sidewalks, paved parking areas, roof areas from attached and detached single-family homes, landscaped areas and other hardscape. These basins are intended to be captured via the on-site storm drain system and routed to Pond C at the southwest corner of the site. The outlet flows from Pond C will be routed to the existing 24" RCP that runs parallel to the south property boundary and discharges into Stanton Creek on the east side of South College Avenue. D-Basins: These basins are not to be captured and conveyed offsite via the proposed on-site storm drain system. Basins D2 and D3 are largely comprised landscaped areas and sidewalk that runs parallel to Galloway & Company, Inc. Page 8 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 South College Avenue. Due to the location of these basins directly adjacent to the South College Avenue right-of-way, runoff generated in these basins cannot be captured via the on-site storm drain system and will runoff directly into College Avenue. Basin D4 consists of the Basin D4 consists of landscaped areas. Existing runoff in this basin flows north in a swale to an existing FES (DP 14 in Shenandoah PUD Filing One) and outfalls into POND 18 (Shenandoah PUD Filing One). The proposed condition, which reduced the tributary area (0.748 ac to 0.29 ac), should have a negligible impact on the existing detention pond. Due to the location of basin D5 directly adjacent to the Triangle Drive right-of-way, runoff generated in these basins cannot be captured via the on-site drainage system and will runoff directly into Triangle Drive. Basin D5 is similar in size and composition (i.e., vegetation) to the existing condition as well as the portion of basin 19 south of Triangle Drive that was delineated with Shenandoah PUD Filing One. Basin D6 is located along the south property boundary of the site and consists of the existing wetland area and vegetation. Runoff from this basin will sheet flow east along existing grades and off-site. Galloway & Company, Inc. Page 9 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 IV. DRAINAGE DESIGN CRITERIA REGULATIONS This final drainage design presented herein is prepared in accordance with the Fort Collins Stormwater Criteria Manual (December 2018). DEVELOPMENT CRITERIA REFERENCE AND CONSTRAINTS The project site is enveloped entirely within the Fossil Creek drainage basin, as delineated by the City of Fort Collins Drainage Basin Master Plan. The Drainage Basin Master Plan was approved by City Council in June of 2004 and describes the flooding history of the specified basins and offers guidance for new development within the basins. Several site-specific constraints helped develop the Low Impact Design Water Quality BMPs and detention pond design presented here. • The outfall for proposed Detention Pond A and Detention Pond B is the inlet swale at the northeast corner of the site that drains to a 48" RCP culvert under South College Avenue. • The outfall for the proposed Detention Pond C is a 24" RCP storm sewer that runs parallel to the south property boundary. This storm sewer passes under South College Avenue where it discharges into Stanton Creek on the west side of South College Avenue. The 24" RCP was designed and constructed with the Ridgewood Hills P.U.D. 3�d Filing. • The project site currently drains from west to east at slopes ranging from 2% to 50%. The steeper slopes up to 50% occur adjacent to the east property boundary at South College Avenue; however, slopes as steep as 30% exist at several locations throughout the project site. • The property has direct frontage along South College Avenue to the east and Triangle Drive to the north. • The existing soils are unsuitable for infiltrating stormwater runoff and generally consist of clayey sand/sandy lean clay and/or lean clay with sand subsoils. Due to the project site being encumbered by these constraints, we developed a strategy for implementing "The Four-Step Process" for stormwater quality management to the Maximum Extent Practicable (MEP). Each step is listed below along with a brief narrative describing the implementation strategy. Step 1— Employ Runoff Reduction Practices To the Maximum Extent Practicable (MEP) the proposed development plan will Minimize Directly Connected Impervious Areas (MDCIA) by directing roof runoff in the B- and C-basins to lot line grass- lined and landscaped swales before draining to the adjacent curb and gutter. All developed runoff from the A-, B- and C-basins will be routed through on-site detention ponds Pond A, Pond B and Pond C, respectively. The detention ponds will restrict the flowrate of stormwater leaving the site and reduce the impact on downstream drainage areas. Step 2— Implement BMPs that provide a Water Quality Capture Volume The proposed design allows for ±90% of the project's newly added impervious area to be routed through an approved LID water quality treatment Best Management Practice (BMP). In the A-basins, ±39% of the total newly added impervious area will be routed through an ADS StormTech chamber system; In the C-basins, ±51 % of the total newly added impervious area will be routed through a Rain Garden (RG)/bioretention area. Galloway & Company, Inc. Page 10 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 The developed runoff from the basins, which will not be routed through an LID BMP, will be treated for water quality in an Extended Detention Basin (EDB) in Pond B before it is piped directly into the Inlet Swale that flows into the 48" RCP culvert under South College Avenue. Step 3 — Stabilize Drainageways Portions of the existing Louden Ditch are to be removed and replaced with an underground pipe system. The Robert Benson Lake Inlet Swale will be preserved to the greatest extent possible. Tributary areas to the Inlet Swale will be piped across the project site. Earthen swales and embankments will be stabilized with vegetation. Retaining Walls are proposed along the east side of the project site to allow for the proposed grading to tie-into the existing grades. Step 4— Implement site specific and other source control BMPs An erosion and sediment control plan and Stormwater Management Plan will be implemented to prevent erosion and control sediment on the project site and downstream drainageways during and after construction. HYDROLOGICAL CRITERIA For urban catchments that are not complex and generally 160 acres or less in size, it is acceptable to estimate the design storm runoff with the rational method. The rational method is often used when only the peak flow rate or total volume of runoff is needed (e.g., inlet sizing, storm sewer sizing or simple detention basin sizing). The Rational Method is based on the Rational Formula: Q = CiA where: Q= Peak rate of runoff, cfs C = Runoff coefficient, dimensionless i= Average intensity for a duration equal to the time of concentration, in/hr A = area, acres The runoff coefficient, C, for each basin is a weighted average of the runoff coefficient associated with each surface type (e.g., asphalt/concrete = 0.95). Refer to Appendix A and Table 3.2-2 which lists the runoff coefficient associated with common surFace types and Table 3.2-3 which lists the Frequency Adjustment Factors (Cf) that were used to adjust the runoff coefficients for lower probability storm events. The one-hour rainfall Intensity-Duration-Frequency tables for use with the Rational Method of runoff analysis are provided in Table 3.4.1 (refer to Appendix B). The 2-year and 100-year storm events serve as the basis for the drainage system design. The 2-year storm is considered the minor storm event. It has a fifty percent probability of exceedance during any given year. The 100-year storm is considered the major storm event. It has a one percent probability of exceedance in any given year. The 2-year drainage system, at a minimum, must be designed to transport runoff from the 2-year recurrence interval storm event with minimal disruption to the environment. The 100-year drainage Galloway & Company, Inc. Page 11 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 system, as a minimum, must be designed to convey runoff from the 100-year recurrence interval flood to minimize life hazards and health, damage to structures, and interruption to traffic and services. HYDRAULIC CRITERIA STREET CAPACITY ANALYSIS The street encroachment standards presented Table 2.1-1 were used to establish minor storm event street capacity, and the street encroachment standards in Table 2.1-2 were used to establish major storm event street capacity. The minor storm event street capacities were estimated with the Modified Manning Equation and Excel. The major storm event street capacities were estimated using Bentley FlowMaster. Refer to Appendix C for the street capacity calculations. The No. 16 Combination inlet and Type `R' curb inlet capacity was estimated with the current Excel-based version of UD-Inlet_v4.05.xlsm (UDFCD). The Nyloplast inlets were sized with capacity charts provided by Nyloplast. In most basins, we selected an inlet grate that provided 2x Q,00 capacity at the maximum allowable ponding depth. The storm drain system hydraulic analysis was completed using Bentley StormCAD V8i. This software routes flows based on the longest upstream Time of Concentration (t�) at each junction. Given the controlling t�, StormCAD V8i calculates the flow at the junction with the corresponding intensity (e.g., iz and i�oo) and aggregate CA. Riprap sizing calculations will be provided in a follow-up submittal. Galloway & Company, Inc. Page 12 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 V. DRAINAGE FACILITY DESIGN GENERAL CONCEPT This Final Drainage Report presents the design of a system for collecting and conveying developed runoff from the proposed Ridgewood Hills Fifth Filing project site into the on-site stormwater quality BMPs and detention ponds. Developed runoff generally consists of flows generated from roof areas, paved roads/drives and parking areas, landscaped areas and hardscape. The developed runoff for each basin begins as overland flow at numerous locations throughout the project site. The runoff then flows via a stormwater conveyance system consisting of swales, curb and gutter and underground storm drain pipes into water quality BMPs and detention ponds. SPECIFIC DETAILS A-Basi ns These basins comprise approximately 8.89 developed acres tributary to Pond A. The developed runoff from these basins is captured via a system of swales, curb and gutter, storm drain system A and routed into the underground ADS StormTech chamber system which follows a modified design procedure to meet City of Fort Collins LID design criteria. Runoff treated in the ADS StormTech chamber system outfalls into Pond A. The ADS StormTech chamber system tributary area from the A-Basins is 7.98 acres. The StormTech chamber system is manufactured by Advanced Drainage Systems, Inc. (ADS). When a modified sizing calculation is used, this system is an allowed method by the City of Fort Collins for the Low Impact Development (LID) stormwater management technique requirements. The ADS StormTech system utilizes underground chambers and aggregate with a void ratio of ±40% to hold the Water Quality Capture Volume (WQCV). The system is designed to infiltrate the WQCV through a filtering fabric on the floor of the chambers over 40-hours, removing contaminants. An underdrain system captures the filtered runoff and conveys it to Pond A. The required WQCV was determined comparing two methods - the greater of the two dictating the volume required. The Mile High Flood District Extended Detention Basin (EDB) sizing calculations and the City of Fort Collins Modified FAA Method for the Water Quality Event (80% Annual Probability Storm Event) were compared. The system is designed to externally bypass the estimated 100-year inflow of ±55.3 cfs. Refer to Appendix C for the ADS StormTech system sizing calculations and final design details. In general, the on-site detention ponds were sized using the City of Fort Collins Modified FAA Method for the 100-year storm event. The allowable release rate for projects within the Fossil Creek drainage basin is 0.2 cfs/acre of tributary area. The allowable release rate for Pond A is 1.8 cfs. The estimated volume of 84951 cu. ft. provides the required detention volume for the 100-year storm event. Calculations for the sizing of the Detention Pond A are included in Appendix C. The detention pond will discharge via an outlet structure that conveys discharge from the pond directly into the Robert Benson Lake Inlet Swale and eventually to the 48" RCP culvert under South College Avenue. RBS-Basin Shenandoah PUD Filing One releases ±129.2 cfs to the Robert Benson Lake Inlet Swale, which then flows underneath U.S. 287 in an existing 48" RCP. The approved Shenandoah PUD Filing One Final Drainage Report estimated the maximum capacity of this pipe at ±228.5 cfs. Ridgewood Hills Fifth Filing Galloway & Company, Inc. Page 13 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 will contribute additional flow totaling ±2.6 cfs to the existing swale, 1.8 cfs from Pond A and 0.8 cfs from Pond B. The North Louden Ditch contributes ±2.0 cfs. B-Basi ns These basins comprise approximately 3.82 developed acres tributary to Pond B. The developed runoff from these basins is captured via a system of swales, curb and gutter, storm drain system B and routed to Pond B. The allowable release rate for Pond B is 0.8 cfs. The estimated volume of 25876 cu. ft. provides the required detention volume for the 100-year storm event. In addition to detention volume for the 100-year return period, the detention is designed as an Extended Detention Basin (EDB) to capture the required WQCV of 2526 cu. ft. for the B-Basins. The total volume provided in Pond B is 28402 cu. ft. Calculations for sizing Pond B are included in Appendix C. The detention pond will discharge via an outlet structure that is connected to a storm drain system that conveys discharge from the pond directly into the Robert Benson Lake Inlet Swale and eventually to the 48" RCP culvert under South College Avenue. C-Basi ns These basins comprise approximately 14.44 tributary acres to Pond C. The developed runoff from these basins is captured via a system of swales, curb and gutter, storm drain system C and routed through the above ground Rain Garden (RG)/bioretention area to Pond C. The developed runoff treated in the Rain Garden (RG)/bioretention area will infiltrate through the filter media into an underdrain system that outfalls into basin WT2, a proposed wetland mitigation area. Developed runoff from the C-basins will drain into the Rain Garden (RG)/bioretention area which the Mile High Flood District (MHFD) defines as "an engineered, depressed landscape area designed to capture and filter or infiltrate the water quality capture volume (WQCV). BMPs that utilize bioretention are frequently referred to as Rain Gardens (RGs) or porous landscape detention areas (PLDs)." During storm events producing excess runoff exceeding the WQCV, the Rain Garden (RG)/bioretention area is designed to fill to the design volume and spill excess runoff into Pond C. The incoming runoff will spill through a weir designed to pass the 100-year incoming flows at a flow depth of ±6". The downstream face of the spillway will be protected with a Turf Reinforcement Mat (TRM). The spillway and downstream protection are designed to pass ±76.8 cfs, the peak 100-year developed runoff entering the Rain Garden (RG)/bioretention area. The allowable release rate for Pond C is 2.9 cfs. The estimated volume of 120769 cu. ft. provides the required detention volume for the 100-year storm event. Calculations for sizing Pond C are included in Appendix C. Pond C will discharge via an outlet structure that is connected to a storm drain system that conveys discharge from the pond directly into the 24" storm drain that runs parallel to the south property boundary and was constructed with the Ridgewood Hills PUD 3�d Filing. The existing outfall pipe drains east underneath South College Avenue and south of Carpenter Road. The alignment outfalls approx. 1515 I.f. east of U.S. 287 and into a swale tributary to Stanton Creek. The existing outfall is 24" dia. increasing to 30" east of U.S. 287. Refer to Appendix D for as-built drawings of the existing outfall. Avondale Road Improvements An extension of Avondale Road is proposed with the Ridgewood Hills Fifth Filing. The road will be dedicated as public right-of-way and will connect the northwest corner of the proposed development to Galloway & Company, Inc. Page 14 of 19 FINAL DRAINAGE REPORT — Ridgewood Hills Fifth Filing June 5, 2024 the southeast corner of the site. The roadway will connect to an extension of Avondale Road to the project's west property line that was constructed with the Ridgewood Hills Fourth Filing. A series of curb inlets in Avondale were constructed within Ridgewood Hills Fourth Filing to maximally intercept runoff before it continues southeast down the portion of Avondale Drive proposed with this project.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

In such cases a composite runoff coefficient must be calculated for any given drainage sub-basin. The composite runoff coefficient is obtained using the following formula: „ � (c;xA; ) C = '-' A, Where: C= Composite Runoff Coefficient C; = Runoff Coefficient for Specific Area (A;), dimensionless A; = Area of Surface with Runoff Coefficient of C;, acres or square feet n= Number of different surfaces to be considered At= Total Area over which C is applicable, acres or square feet 3.2.2 Runoff Coefficient Frequency Adjustment Factor Equation 5-2 The runoff coefficients provided in Table 3.2-1 and Table 3.2-2 are appropriate for use with the 2-year storm event. For any analysis of storms with higher intensities, an adjustment of the runoff coefficient is required due to the lessening amount of infiltration, depression retention, evapotranspiration and other losses that have a proportionally smaller effect on high-intensity storm runoff.

U.D., Filing No. 3 4.2 for basins 821, 925, OS-1 through OS-5 and basins 1000 - 1004, entire lots or portions thereof, street flows and open space tracts account for much of the area in the remaining basins. Developed flows for each basin are conveyed to the design point (for that basin} or to a common design point (far a combination of basins) via overland flow, grass lined side-lot swales, rear lot swales; and curb and gutter. Basin Descriptions Basins OS-1 (3.35 ac) and OS-2 (0.79 ac) are Iocated along the West property line and drain areas comprised mostly of lawns or landscaping and undeveloped areas. The Historic Basins Exhibit (See Appendix A) shows an area along the west property boundary of approximateiy the same area as OS-1 and OS-2. This basin shoutd release at less than historic rates without adversely affecting the historic drainage pattern. Care was taken during the 'grading design of lots bordering these basins to ensure that all impervious areas from rooftops and concrete surfaces would drain toward the east into the streets. Basins OS-3 through OS-5 are located along the East property line. Basins OS-3 (0.42 ac) and OS-5 (0.05) are of negligible size and drain mostly landscaping and undeveloped area. Basin OS-4 (5.16 ac) will remain undeveloped for now and drain to the east per historic drainage patterns. In the future, this parcei will be developed as a multi-family site. Developed flows from the future development will be routed through one of the two on-site detention ponds that are being proposed as part of the Ridgewood Hills P.U.D., Filing No. 3 improvements. Both Pond #1 and Pond #2 have sufficient capacity to handle future developed flows from this area. 6 N:\FC0045.NEW�Drainage\WordlDmgRpt041 I OO.doc this unofficial copy was downloaded on Aug-27-2019 from the City of Fort Collins Public Records Website: http://citydocs.fcgov.com �or additional infonnation or an official copy, please contact City of Fort Collins Utilities 700 Wood Street Fort Colli��s, CO 80524 USA � \ .�J � 0 E Y O N D E N G 1 N E E R 1 N G Fina! Drainage & Erosion Control Study Ridgewood Hills P. U.D., Filing No. 3 This inlet and the 5' Type `R' on the west side are designed to fully capture 100- year developed flaws. In cases where the upstream inlets are blocked, carryover flow from D.P.'s 807, 808; 849 and 817 will spill to the low point in Fountain Drive. If the inlets in Fountain are blocked, the combined flows overtop the curb and spill directly to Pond #2 (Refer to the Swale Design section of AppendiY C for cross-sections). The embankment in Pond #2 will be protected with American Green P300 Erosion Control/Turf Reinforcement Matting. Developed flows of 47.92 cfs from basins 915 and 917 concentrate to a 43' No. 16 combination inlet at D.P. 917. The inlets are designed to capture 100-year developed flows in ihis area and release a O.I6 cfs carryover flow to future off-site development along Avondale Road. Likewise, a 100-year developed flow of 5.14 cfs at D.P. 918 is captured by a No. lb combination inlet. The carryover flow to the future off-site development is 0.05 cfs. � The developed flows from the aforementioned basins {915, 917 and 918) combine with overland flows from basin 821 (future commercial development, Tract F} and developed flow from basins 818 and 819 (D.P.'s 818 and 819) in Storm Drain System "E". This system outfalls to.Pond #2. Calculations in Appendix B show that Storm Drain Systern "E" has capacity for the 100-year developed flows (Q,Qo= 53.01 cfs) that accumulate at D.P. 821. Water will pond around the flared end section (F.E.S.) up to 5073.01 (the berm around the F.E.S. is graded to I 50.75.0). Refer to Storm Drain System "E" in Appendix C for calculations. The discharge capacity of the pipe was calculated with ihe tailwater elevation in Pond #2 set to the lOQ-year W.S.E.L. This candition is temporary until the proposed commercial property is fully developed. 9 N:\FC0045.NEW�DrainagelWord\DmgRpt041100.doc ['his unofficial copy was downloaded on Aug-27-2019 from the City of Fort Collins Public Records Website: http://citydocs.fcgov.com 'or addifional information or an ot�icial copy, please contact City of Fort Collins UfiliCies 700 Wood Street Fort Collins, CO 8052�4 USA � A � `�' Z o p oc � c� a U � � _ � c� � z � o a rn w � � oi a p Z � S O � O w � � N U i� co 0 �'or additional infonnation or au official copy, please contact Engineering Office 281 Nortl� College Fort Collins, CO 80521 USA I � NC�LTE 0 E�' p N O E N G� N E E R 1 N G Fina! Drainage c� Erosion Contro! Study Ridgewood Hills P. U.D., Filing No. 3 The tailwater downstream of our outlet structure was accounted for in•the design of Pond # i. The downstream system was originally designed to accept 25 cfs from our Site. We re-evaluated the downstream tailwater condition using ihe proposed Pond #1 release rate of 9.9 cfs. The autlet structure will operate under inlet control. Refer to Appendix E for portions of the approved Final Drainage Report for Shenandoah P.U.D., First Filing. The outlet system for Pond #2 regulates the release rate at 10.I cfs (Q>H,5=10.1 cfs) through a 11-1 /2" diameter orifice plate. Pond #2 discharges to the proposed off-site storm drainage system (See Appendix D}. The design of the system is included as part of the Ridgewood Hills P.U.D., Fiiing No. 3 drainage improvements. � The Pond #2 outfall connects to the proposed off-site system at a manhole in the. southeast corner of the Site. From here, the system heads directly east and across the property owned by Colorado Land Source. A letter of intent from Colorado Land Source (dated December 14, 1998) has been submitted to the City of Fort ' Collins. The developed runoff will be piped under College Avenue and across the Coiland Center Third Filing property in existing road right-of-way and an existing drainage easement. The pipe will daylight east of the Colland Center Third Filing property into an existing swale. Nolte Associates, Inc. is working with the , engineer for Colland Center Third Filing, Northern Engineering Services, Inc., to design a common outfall for this line and the outfall from their proposed detention pond. The existing swale has a capacity of approximately 124 cfs (Note: representative cross-sections downstream of the proposed outfall, which were selected following a site visit, are included in Appendix C}.

North Louden Ditch and Reservoir Company Matthew Pepin, P.E. Galloway 4/14/2023 Ridgewood 5th - No. Louden Realignment Memorandum Louden Ditch will be realigned to incorporate the development of Ridgewood Hill Filing No. 5. The ditch will become piped and experience open channel flow in the proposed condition. Galloway analyzed the ditch in the proposed condition to determine if the ditch would function in a satisfactory manner to meet Louden Ditch Board Standards. Galloway assumed that common flows through the system would be between 2 CFS and 5 CFS. The model also included a split flow condition at structure IRR A-8 at the northern part of the system. This flow would constantly allow for 2 CFS to be conveyed east outfalling at S- 26. Thus, no flow would be conveyed north in this condition. In the 5 CFS model, 3 CFS would be routed to the north. Within each of these conditions, the model would analyze velocities within the system to determine if sedimentation would occur and how HGL (hydraulic grade line) functions with the shallow grade. In the below table, minimum and maximum velocities within the ditch when conveying flows 2 CFS and 5 CFS. Louden Ditch Realignment Velocity in Pipe(ft/s) Velocity in Ditch Min. Max. 2 CFS 1.7 8.9 5 CFS 1.7 8.9 Min. Max. 0.4 0.72 0.5 0.95 While velocities do remain low within the system, the HGL's remain above the pipe inverts, thus proving flows would not become stagnant within the ditch. Refer to attached output of HGL information in Appendix of this memorandum. In conclusion, Galloway believes with the current hydraulic analysis, the ditch would perform to the Louden Ditch Board Standards and no adverse impacts are to result from this realignment.
