Details added and changed along the north boundary of the site and on the adjacent St Francis property necessitated these changes. This report identifies the drainage design criteria used, and describes the design of the project drainage and retention system. The analysis identifies the 10 year and 100 -year storm runoff rates and volumes generated within the areas tributary to Tract 35060 that are used in the design of the onsite streets, inlets, drainage pipes, slope cutoff ditches and retention basins. Existing Site Description The site measures approximately 1390 by 1380 feet, consisting of approximately 29 onsite acres and 43 tributary acres, located adjacent to the west side of Washington St, at the intersection with Avenue 48, within the City of La Quinta, County of Riverside, California. It is bounded on the east by the Washington Street Right of Way; on the west by a steep rock mountain; on the north by the vacant sand and rock property of the St Francis of Assisi Church; and on the south by an existing Condominium Resort project The site occupies some of the lowest ground in the vicinity, and is currently used as an event overflow parking lot and retention basin. Proposed Proiect Description Tract 35060 is a project by Laing Luxury Homes to develop 74 single - family residential lots, homes, and associated improvements on the site. Site development includes full improvement of all onsite areas, connection of the onsite streets to Washington St ' at the center of the east side of the site and at the north end of the project on the adjacent property, and retention of drainage from the 28 acre site, 6.2 acres of offsite rock mountain and 7.5 acres of sand to the west. Laing Luxury Homes has entered into an agreement with the St Francis of Assisi Catholic Church to construct the first phase of an access drive into the future church parking area. This drive entrance also provides a secondary access to subject Tract 35060 as required by the fire department. Development also includes interim graded drainage ditches and enlargement of the existing natural retention basin on the Church property. (See Tab 3, Summary 3). Development includes concrete cutoff ditches to contain and control the onsite slope drainage along the south, and offsite slope drainage along the west and north boundaries. ' The historic drainage relief overflow locations and elevations along Washington St are preserved as shown on Exhibit 2, Tab 12. Fire access is provided from Washington St at the central entrance and at the common use driveway access shared with the St Francis site near the northeast corner of Tract 35060. An agreement with the St Francis of Assisi Catholic Church has been finalized with the church leadership. .Existing Drainage Patterns ' (See Tab 12, Exhibit 1 and 2 for the existing and historic drainage control elevations). South: An existing masonry wall along the south tract boundary will remain and prevents any drainage between Tract 35060 and the existing condominium resort to the south. West: There is a development limit line along the west side of the site prohibiting development of the rock and higher sand portions of the mountain. This line is shown on Exhibit 1 and Exhibit 2, Tab 12 of this report. MDS 69400 5/20/2008 ' The rock and sand mountain along about 2/3 of the west site boundary drains to an existing graded swale along the limit line, and is then channeled south to an existing, graded, 1/3 acre retention basin at the southwest corner of the site. The rock and sand mountain along the north 1/3 of the west site boundary drains north in a graded ' swale along the west side of an existing paved drive, to a small, existing retention basin in the northwest corner of the site. This basin then overflows into said drive and flows east along the street into a large gravel paved parking lot along the east side of the site. This parking lot appears to function as a large, shallow retention basin, with an ' average bottom elevation of 53.4 and an overflow elevation into Washington St of 58.1. North: A large, elevated sand access ramp has been constructed by the St Francis of Assisi Catholic Church about 60 feet north of the site boundary. The south slope of this ramp currently drains south into Tract 35060 and the existing drive along the north boundary, and then drains east into the gravel surfaced parking lot / retention basin described above. This offsite ramp prevents the historic natural drainage of the west portions of the St Francis parcel to its historic collection point in the southeast corner of the St Francis parcel. It is necessary for the historic offsite drainage pattern of the St Francis parcel to be reestablished when it is developed. ' Onsite: Tract 35060 currently drains east across the site from the west boundary to the parking lot / retention basin along the east boundary, and ultimately into Washington Street. ,East: Washington Street borders the east side of Tract 35060. There is an existing high point in the street profile approximately 200 feet south of the northeast corner of Tract 35060. The St Francis site, and Washington Street north of the high point, drain north to the historic low area in the southeast corner of the St Francis site. The historic drainage relief for this low area overflows east across Washington Street and east along La Quinta Lakes Drive into the lake at the existing La Quinta Lakes Development. Washington Street south of the high point drains south along the Tract 35060 frontage to two curb inlets which drain into the onsite parking lot / retention basin. The historic outlet at the southeast tract corner (el 58.3) flows ' south for several hundred feet to curb inlets.at the low point in the Washington St profile. If these inlets were to fail, the runoff then ponds to the Street centerline low point elevation (approximate el 56), flows east over the centerline, ponds in the low point on both sides of Washington St until it reaches the overflow elevation at the southeast curb return of Ave 48 and Washington St. (el 58.1), and then surface flows east along the south curb of Ave 48 to the flood channel .crossing Ave 48 at Dune Palm Dr. Proposed Drainage Patterns Tract 35060 is designed to preserve the historic offsite drainage patterns. Offsite grading along the south, and west tract boundaries is prohibited. Recent agreements with the Church require grading of ditches and swales on the church property to redirect the ' church drainage into the existing low area in the southeast corner of the church property. The site grading and the site drainage system are designed to direct both offsite and onsite drainage to two, large interconnected retention basins along the Washington Street frontage, and one small basin in the southwest corner of the site. St Francis Church drainage The portion of the Church property draining to the southeast corner of the church property is 41.2 acres, generating a peak storm volume of 9.5 Acre Ft, assuming zero percolation, per city requirements. There should be considerable percolation in the higher; west portions of the site, but may be little percolation in the low, Basin 4 area adjacent to Washington St., because of long term drainage and sealing in this area. IMDS 69400 5/20/2008 Proposed grading of Basin 4 occurred due to loss of existing volume of the basin itself with incorporation of the proposed Private Church Drive. Proposed grading for Basin 4 provides some slight additional increase in basin storage volume from the existing condition. The capacity of the expanded Basin 4 is less than 3.4 AcFt. (1/3 ' required volume) using the overflow elevation of the Washington Street median, which assumes flooding of both sides of the street (see Tab 3, Summary 5C). The proposed slight enlargement of Basin 4, and redirecting of the church site runoff to Basin 4, improves the existing drainage condition considerably, but does not solve the St. Francis of Assisi Church site drainage conditions in coordination with City and County standards, as this is not a part of the Tr. No. 35060 scope or ' required per project conditions of approval. Future development of the Church expansion will need to accommodate the drainage conditions within this area. Rough Grading Plans and Storm Drain Improvement plans, with regard to Basin 4, reference a maximum water ' surface elevation using the adjacent Washington Street lowest edge of pavement elevation (57.00). ' South: The existing property line masonry wall will be preserved. The proposed lots along the north side of this wall will be slightly higher than the existing landscaped area on the south side. An earth swale and French drain will be constructed between the north face of the wall and the south toe of the resulting onsite lot slope. The existing ground along the wall footing slopes to the west, requiring that the swale also slope west. A small graded basin ( #3) is being provided at the southwest Tract corner to retain runoff from this lot slope. Onsite drainage will not be allowed to pond against the existing property line wall. Therefore, the maximum water surface in Basin 3 shall be at or lower than the lowest ground elevation at the base of the existing wall, (elev ' } 56.2). (See Tab 3, Summary 4 for Basin 3 Control Elevations) Drainage into the adjacent development to the south is prohibited, and the lowest possible onsite surface overflow ' is west over the ditch bank into inlet DI -1 at elevation 58.0. In lieu of a surface overflow, basin 3 is arbitrarily sized to provide 200% of the storage volume required for the 100 year, 24 hour, design storm, (7440 cf) with a peak water surface elevation of 56.2: This provides adequate storage for a storm larger than the theoretical 1000 -year storm, (159 % of the 100 yr storm). (See NOAA Point Precipitation table in Tab 11, References.) West: The Development limit line will be preserved. The mountain along the west boundary will not be graded and will continue to drain to the west boundary at the limit line. Concrete lined vee ditches will be constructed along the boundary / limit line to intercept the offsite mountain runoff. These swales are adequately sized to convey the 100 -year, 1 -hour design storm to inlets into the storm drain and retention system. All design storm flows are determined using the Riverside County Rational Hydrology Method. Calculations are contained in Appendix B, Tabs 6, thru 9. The existing site slopes steeply from west to east, requiring extensive cutting along the north 2/3 of the west side of the site. The cut slopes will be stabilized with retaining walls. A small concrete swale will be constructed at the top of each slope and wall to convey the drainage from the slope above the wall to storm drain inlets DI 1 through 5. North: Extensive cutting is also required along the westerly 2/3 of the north boundary. Part of this slope is contained within the site, and a portion of the slope is on the adjacent church property. A property line privacy wall and small concrete vee ditch will be constructed at the tract boundary. This wall will intercept existing drainage from the St Francis Church site until the offsite property is improved and intercepts and disposes of all of its onsite drainage. All vee ditches and inlets are sized and sloped to convey the 100 -year, 1 -hour design storm. MDS 69400 5/20/2008 Onsite: The proposed lot pad elevations along the south boundary have been set as low as possible relative to the existing homes to the south to preserve the views of the latter. The pad grades along the west and north boundaries have been kept as high as practical to minimize the cut along the west and north boundaries. This results in the proposed site sloping from the northwest corner to the southeast corner. All onsite storm drainage is conveyed by surface flow in the streets to curb inlets. All offsite storm drainage is intercepted at the boundaries, combined with the onsite drainage in storm drain systems along the north and south streets and conveyed to grated distribution boxes in the bottom of the retention basins. The system is sized to convey the 100 -year, 24 -hour design storm volume and the 100 year, 1 hour storm peak flows to the two retention basins along the east boundary. Large storm flows "bubble -up" through the top grate of the distribution boxes, spread over the bottom of the retention basins, and percolate into the bottom and sides of each basin to the extent limited by the nature of the onsite soils in the retention basins. The tested percolation rate of the soils in the retention basins varies between 0.2 and 1.2 inches per hour. Per COLQ standards, the design percolation rate used for sizing of the Retention Basins is zero, and the design rate used for calculating the time required to empty the basins after a storm is the sum of the average of the tested rates for the basin areas and the drywell locations. Small Nuisance water flows are disposed of in Nuisance Water Disposal System drywells (NWDS). (See discussion below). Retention basins 1 & 2 are interconnected so they function as one. The connector pipe, Storm Drain D, is sized to equalize the average inflow and storage volumes in the basins during the peak inflow portion of the design storm. The retention basins are designed to provide 100 year, 24 hour storm storage with 1.0 foot or more of freeboard between the water surface in the basin and the, normal gutter flow line at the lowest inlet, and to also provide 1.0 foot minimum of freeboard between the highest possible overflow water surface in the retention basins or the storm drain system and the lowest building pad. The combined Retention Basins 1 and 2 provide the required storage; (347,130 cubic feet, 7.969 Acre feet), for the largest design storm while conforming to the above requirements. (See Tab 3, Summaries 4 and 5.) East: The Washington Street frontage will be improved with curbs, inlets, bus turnouts, and entrances for general and fire access traffic, but the street profile grades will not be changed. The high and low points and historic relief elevations and locations will all be preserved. A curb inlet (CB# 10) will be installed at the northeast Tract Corner to intercept the small amount of frontage drainage flowing north toward the St Francis Church frontage. A curb inlet (CB# 13) will be installed on the upstream side of the entrance drive, to eliminate water flowing through the intersection, and the existing combined curb inlet and drywell (CB #9) at the extreme low point of the street profile will be modified and reused. Ultimate Drainage relief from the retention basins will flow out of the inlet at the street low point, (CB# 9 — Elev 57.57), or will surface overflow the top of the south retention basin berm into Washington Street at elevation 59.2. It will then overflow the historic Washington Street gutter flow line high point at.the southeast Tract corner (elev 58.3), overflow the Washington St centerline just south of Ave 48 (approximate elev 58.6), and overflow the gutter flow line high point at the southeast curb return of Washington St and Ave 48, (Elev 58.1). All overflow elevations are determined assuming total blockage of the storm drain system and surface outflow only. 4 IMDS 69400 Proposed Drainage System Design Methods See Tab 3, Summary 1 and the discussion above for the Design Criteria used. 5/20/2008 The Riverside County Synthetic Unit Hydrograph Method is used to determine the storm runoff volumes of the potential design storms (100 yr — 1 hr, 3 hr, 6 hr, & 24 hr). A Flood Routing program is used to determine the net required retention basin storage for each potential design storm if deduction of percolation from the basins is allowed, and is used to compute the time required to drain the Basins after the design storm. The total onsite and offsite drainage areas for the retention basins are evaluated for the runoff from the design storms. The storm yielding the largest required storage volume is designated the design storm for the Basins. The 24 hr storm is the controlling storm for this project. (See Tab 3, Summary 6, and Tabs 4 and 5, Appendix Al & A2). A CivilCadd / CivilDesign computer program using the Rational Method outlined in the Riverside County Flood Control District Hydrology Manual is used in calculating the required and actual capacity of each street, inlet, and storm drain. structure (See Appendix B1, B2, and B3, Tab 6, 7 and 8). A Water Surface Profile Design program is used to calculate the Hydraulic Grade Lines (HGL10 and HGL100) for each pipe system at maximum flow. (See Tab 9, Appendix B -4). The pipes are sized to provide 0.5 -foot minimum freeboard between the 100 -year, 24 -hour water surface in each inlet and the normal gutter flow line at each curb opening. (See Tab 3, Summary 4 for the control elevations for the drainage system and Summary 8 for the inlet freeboard summary data). Storm drain A is oversized to decrease the slope of the Hydraulic Grade Line to prevent backwater from Basins 1 & 2 from ponding against the existing wall at inlet DI#-1 at the southwest Tract corner. Per COLQ requirements (Paul Goble), HGL10 calculations start at or above the water surface elevation in the basins corresponding to half the water depth at peak 100 year storage, and HGL100 calculations start at or higher ' than the water surface elevation in the basins at the time of peak 100 year inflow, not at peak storage, when the pipe flow has stopped. Bulking: Bulking of storm runoff in concrete lined vee ditches and pipes is not considered a factor in the design for these facilities for the following reasons: • This is a desert environment with no significant vegetation on the rock ridge or the sand slope, and no potential for vegetative debris caused bulking. • The rock is massive with no significant loose fragments small enough to be dislodged by storm runoff, and no potential for rock and gravel caused bulking. 0 The sand slopes are wind deposited. The sand is very small, fine, and light and will be easily transported in the runoff without retarding flow and causing significant increase in volume (bulking). • Settling areas in the storm drain inlets are provided to catch the water transported sand. The concrete ' lined ditches and settling areas must be cleaned as needed after storms. • The small sand grain size should ensure that any wind deposited material deposited in the ditches between storms will be flushed out at the beginning of the next storm. MDS 69400 Nuisance Water Disposal 5/20/2008 Nuisance water is defined as silt and contaminant - carrying runoff from landscape irrigation and the debris and contaminants flushed from pavement surfaces during the first minutes of storm runoff. It does not include runoff from undeveloped areas. All storm drainage from the onsite and offsite areas is collected in the streets and storm drain system, and flows to distribution boxes in the bottom of the retention basins. The distribution box provides flexibility in connecting deep storm drains to the retention basins without unnecessarily increasing the retention basin depth. Retention Basin depth must be minimized for aesthetic, safety, maintenance, construction and hydraulic efficiency reasons. Large storm flows that exceed the capacity of the Nuisance Water Disposal System (NWDS) will flow out through the top grates of these boxes, spread over the bottom of the retention basins, and percolate into the bottom and sides of each basin to the extent possible. Nuisance water flows smaller than the capacity of the NWDS will follow the same flowpath but will flow from the distribution boxes through small diameter (6inch) pipes to the NWDS, to be clarified and percolated into the ground beneath the bottom of the retention basin. A small lateral pipe (6 inch) may connect two or more distribution boxes to a single NWDS. The NWDS is designed per COLQ and the manufacturers requirements to collect nuisance water from hard surface and landscaped areas, remove debris and floating contaminants and dispose of the clarified water using Maxwell Plus percolation drywells in the bottoms of the basins. The Maxwell Plus and Maxwell IV systems are sized per COLQ and Torrant Industries standards. Percolation ' testing is not required for sizing of the systems when disposing of only Nuisance water. i I 6 � I Tab 3 I -� Summary of � Results i, 5D. 5E. 6. 8. 9.

Auk u st ;2007 Hydrology and Hydraulic Design Report Tract 35060 - City Of La Quinta (Northwest Corner of Ave 48 and Washington St) Purpose This report identifies the drainage design criteria used, and describes the design of the project drainage and ' retention system. The analysis identifies the 10 year and 100 -year storm runoff rates and volumes generated within the areas tributary to Tract 35060 that are used in the design of the onsite streets, inlets, drainage pipes, slope cutoff ditches and retention basins. ' Existing Site Description The site measures approximately 1390 by 1380 feet, consisting of approximately 29 onsite acres and 43 tributary ' acres, located adjacent to the west side of Washington St, at the intersection with Avenue 48, within the City of La Quinta, County of Riverside, California. It is bounded on the east by the Washington Street Right of Way; on the west by a steep rock mountain; on the north by the vacant sand and rock property of the St Francis of Assisi Church; and on the south by an existing Condominium Resort project The site occupies some of the lowest ' ground in the vicinity, and is currently used as an event overflow parking lot and retention basin. Proposed Proiect Description I Tract 35060 is a project by Laing Luxury Homes to develop 75 single - family residential lots, homes, and associated improvements on the site. Site development includes full improvement of all onsite areas, connection of the onsite streets to Washington St �. at the center of the east side of the site, and retention of drainage from the 28 acre site, 6.2 acres of offsite rock mountain and 7.5 acres of sand to the west, and 1.2 acres of offsite slope along the north project boundary. (See Tab 3, Summary 3). ' Development includes concrete cutoff ditches to contain and control the onsite slope drainage along the south, and offsite slope drainage along the west and north boundaries. ' The historic drainage relief overflow locations and elevations along Washington St are preserved as shown on Exhibit 2, Tab 12. Alternate fire access is provided from Washington St between the south tract boundary and Retention Basin One, ' and between the north tract boundary and Retention Basin two. Provision for a future common use driveway access with the St Francis site is made near the northeast corner of Tract 35060. An additional access drive to be shared with the St Francis of Assisi Catholic Church is planned for future construction when the St Francis property develops. The agreement with the church has not been finalized and is dependent on the church leadership. Provision for the future connection has been made in the street and storm drain designs. Existing Drainage Patterns (See Tab 12, Exhibit 1 and 2 for the existing and historic drainage control elevations). ' South: An existing masonry wall along the south tract boundary will remain and prevents any drainage between Tract 35060 and the existing condominium resort to the south. West: There is a development limit line along the west side of the site prohibiting development of the rock and higher sand portions of the mountain. This line is shown on Exhibit 1 and Exhibit 2, Tab 12 of this report. The rock and sand mountain along about 2/3 of the west site boundary drains to an existing graded Swale along the limit line, and is then channeled south to an existing, graded, 1/3 acre retention basin at the southwest corner of the site. The rock and sand mountain along the north 1/3 of the west site boundary drains north in a graded Swale along the west side of an existing paved drive, to a small, existing retention basin in the northwest corner of the site. This basin then overflows into said drive and flows east along the street into a large gravel paved parking ' 1 MDS 69400 8/22/2007 lot along the east side of the site. This parking lot appears to function as a large, shallow retention basin, with an average bottom elevation of 53.4 and an overflow elevation of 58.1. North: A large, elevated sand access ramp has been constructed by the St Francis of Assisi Catholic Church about 60 feet north of the site boundary. The south slope of this ramp currently drains south into Tract 35060 and the existing drive along the north boundary, and then drains east into the gravel surfaced parking lot / retention basin described above. This offsite ramp prevents the historic natural drainage of the west portions of the St Francis parcel to its historic collection point in the southeast corner of the St Francis parcel. It will be necessary for the historic offsite drainage pattern of the St Francis parcel to be reestablished when it is developed. Onsite: Tract 35060 currently drains east across the site from the west boundary to the parking lot / retention basin along the east boundary, and ultimately into Washington Street. East: Washington Street borders the east side of Tract 35060. There is an existing high point in the street profile approximately 200 feet south of the northeast corner of Tract 35060. The St Francis site, and Washington Street ' north of the high point, drain north to the historic low area in the southeast corner of the St Francis site. The historic drainage relief for this low area overflows east across Washington Street and east along La Quinta Lakes Drive into the lake at the existing La Quinta Lakes Development. ' Washington Street south of the high point drains south along the Tract 35060 frontage to two curb inlets which drain into the onsite parking lot / retention basin. The historic outlet at the southeast tract corner (el 58.3) flows south for several hundred feet to a low point in the Washington St profile. The runoff then ponds to the Street centerline low point elevation (approximate el 56), flows east over the centerline, ponds in the low point on both sides of Washington St until it reaches the overflow elevation at the southeast curb return of Ave 48 and Washington St. (el 58.1), and then surface flows east along the south curb of Ave 48 to the flood channel crossing Ave 48 at Dune Palm Dr. 0 Proposed Drainage Patterns Tract 35060 is designed to preserve the historic drainage patterns. Offsite grading along the south, west, and north ' tract boundaries is prohibited. The site grading and the site drainage system are designed to direct both offsite and onsite drainage to two, large interconnected retention basins along the Washington Street frontage, and one small basin in the southwest corner ' of the site. South: The existing property line masonry wall will be preserved. The proposed lots along the north side of this wall will be slightly higher than the existing landscaped area on the south side. An earth swale and French drain will be constructed between the north face of the wall and the south toe of the resulting onsite lot slope. The existing ground along the wall footing slopes to the west, requiring that the swale also slope west. A small graded basin ( 0) is being provided at the southwest Tract corner to retain runoff from this lot slope. rOnsite drainage will not be allowed to pond against the existing property line wall. Therefore, the maximum water surface in Basin 3 shall be at or lower than the lowest ground elevation at the base of the existing wall, (elev 56.2). (See Tab 3, Summary 4 for Basin 3 Control Elevations) Drainage into the adjacent development to the south is prohibited, and the lowest possible onsitecsurface overflow is west over the ditch bank into inlet DI -1 at elevation 58.0. In lieu of a surface overflow, basin 3 is arbitrarily sized to provide 200% of the storage volume required for the 100 year, 24 hour, design storm, (7440 cf) with a peak water surface elevation of 56.2. This provides adequate storage for a storm larger than the theoretical 1000 -year storm, (159 % of the 100 yr storm). (See NOAA Point Precipitation table in Tab 11, References.) West: The Development limit line will be preserved. The mountain along the west boundary will not be graded and will continue to drain to the west boundary at the limit line. Concrete lined swales will be constructed along ' the boundary / limit line to intercept the offsite mountain runoff. These swales are adequately sized to convey the 100 -year, 24 -hour design storm to inlets into the storm drain and retention system. MDS 69400 8/22/2007 i All design storm flows are determined using the Riverside County Rational Hydrology Method. Calculations are contained in Appendix B, Tabs 6, thru 9. The existing site slopes steeply from west to east, requiring extensive cutting along the north 2/3 of the west side of the site. The cut slopes will be stabilized with earth retained walls as much as 20 feet high. A small concrete swale will be constructed at the top of each wall to convey the drainage from the slope above the wall to storm drain inlets. North: Extensive cutting is also required along the westerly 2/3 of the north boundary. This cut slope will also be stabilized with a tall earth retained wall located 25 feet south of the Tract boundary. A small concrete swale will be constructed at the top of this wall to convey the drainage from the slope above the wall to an inlet into the drainage system. All swales and inlets are sized and sloped to convey the 100 -year, 24 -hour design storm. A masonry property line wall will be constructed 10 feet south of the north tract boundary at the existing ground elevation at that location. This wall will intercept existing drainage from the St Francis Church site until the offsite property is improved and intercepts and disposes of all of its onsite drainage. Temporary concrete swales and inlets (Dl -6 & 7) will be constructed at the base of the north side of this wall to intercept drainage from the existing offsite slope of the driveway ramp described above, and convey it into the onsite drainage system. This wall and VeeDitch will be constructed without offsite grading. Onsite: The proposed lot pad elevations along the south boundary have been set as low as possible relative to the existing homes to the south to preserve the views of the latter. The pad grades along the west and north boundaries have been kept as high as practical to minimize the cut along the west and north boundaries. This ' results in the proposed site sloping from the northwest corner to the southeast corner. All onsite storm drainage is conveyed by surface flow in the streets to curb inlets. All offsite storm drainage is intercepted at the boundaries, combined with the onsite drainage in storm drain systems along the north and south streets and conveyed to grated distribution boxes in the bottom of the retention basins. The system is sized to convey the 100 -year, 24 -hour design storm to the two retention basins along the east boundary. Large storm flows "bubble -up" through the top grate of the distribution boxes, spread over the bottom of the retention basins, and percolate into the bottom and sides of each basin to the extent limited by the nature of the onsite soils in the retention basins. The tested percolation rate of the soils in the retention basins varies between 0.2 and 1.2 inches per hour. Per COLQ standards, the design percolation rate used for sizing of the Retention Basins is zero, and the design rate used for calculating the time required to empty the basins after a storm is the average of the tested rates. Small Nuisance water flows are disposed of in Nuisance Water Disposal Systems (NWDS). (See discussion below). Retention basins 1 & 2 are interconnected so they function as one. The connector pipe, Storm Drain D, is sized to equalize the average inflow and storage volumes in the basins during the peak inflow portion of the design storm. The retention basins are designed to provide 100 year, 24 hour storm storage with 1.0 foot or more of freeboard between the water surface in the basin and the normal gutter flow line at the lowest inlet, and also provide 1.0 foot minimum of freeboard between the highest possible overflow water surface in the retention basins or the storm drain system and the lowest building pad. The combined Retention Basins 1 and 2 provide the required storage, (347,130 cubic feet, 7.969 Acre feet), for the largest design storm while conforming to the above requirements. (See Tab 3, Summaries 4 and 5.) East: The Washington Street frontage will be improved with curbs, inlets, bus turnouts, and entrances for general and fire access traffic, but the street profile grades will not be changed. The high and low points and historic relief elevations and locations will all be preserved. A curb inlet (CB# 10) will be installed at the northeast Tract Corner to intercept the small amount of frontage drainage flowing north toward the St Francis Church frontage. A curb inlet (CB# 13) will be installed on the upstream side of the entrance drive, to eliminate water flowing through the intersection, and the existing combined curb inlet and drywell (CB #9) at the extreme low point of the street profile will be modified and reused. 3 MDS 69400 8/22/2007 SUltimate Drainage relief from the retention basins will flow out of the inlet at the street low point, (CB# 9 — Elev 57.57), or will surface overflow the top of the south retention basin berm into Washington Street at elevation 59.2. It will then overflow the historic Washington Street gutter flow line high point at the southeast Tract corner (elev 58.3), overflow the Washington St centerline just south of Ave 48 (approximate elev 58.6), and overflow the gutter flow line high point at the southeast curb return of Washington St and Ave 48, (Elev 58.1). All overflow elevations are determined assuming total blockage of the storm drain system and surface outflow only. Proposed Drainage System Design Methods See Tab 3, Summary 1 and the discussion above for the Design Criteria used. The Riverside County Synthetic Unit Hydrograph Method is used to determine the storm runoff volumes of the potential design storms (100 yr - 3 hr, 6 hr, & 24 hr). A Flood Routing program is used to determine the net required retention basin storage for each potential design storm if deduction of percolation from the basins is allowed, and is used to compute the time required to drain the Basins after the design storm. The total onsite and offsite drainage areas for the retention basins are evaluated for the runoff from the design storms. The storm yielding the largest required storage volume is designated the design storm for the Basins. (See Tab 3, Summary 6, and Tabs 4 and 5, Appendix Al & A2). A CivilCadd / CivilDesign computer program using the Rational Method outlined in the Riverside County Flood Control District Hydrology Manual is used in calculating the required and actual capacity of each street, inlet, and storm drain structure (See Appendix B1, B2, and B3, Tab 6, 7 and 8). A Water Surface Profile Design program is used to calculate the Hydraulic Grade Lines.(HGL10 and HGLI00) for each pipe system at maximum flow. (See Tab 9, Appendix B -4). The pipes are sized to provide 1.0 -foot minimum freeboard between the I00 -year, 24 -hour water surface in each inlet and the normal gutter flow line at the curb opening. (See Tab 3, Summary 4 for the control elevations for the drainage system and Summary 8 for the inlet freeboard summary data). ' Storm drain A is oversized to decrease the slope of the Hydraulic Grade Line to prevent backwater from Basins 1 & 2 from ponding against the existing wall at inlet # DI -1 at the southwest Tract corner. Per COLQ requirements (Paul Goble), HGL10 calculations start at the water surface elevation in the basins corresponding to half the water depth at peak 100 year storage, and HGL100 calculations start at the water surface elevation in the basins at the time of peak 100 year inflow, not at peak storage, when the pipe flow has stopped. ' Bulking: Bulking of storm runoff in concrete lined ditches and pipes is not considered a factor in the design for these facilities for the following reasons: • This is a desert environment with no significant vegetation on the rock ridge or the sand slope, and no potential for vegetative debris caused bulking. • The rock is massive with no significant loose fragments small enough to be dislodged by storm runoff, and no potential for rock and gravel caused bulking. • The sand slopes are wind deposited. The sand is very small, fine, and light and will be easily transported in the runoff without retarding flow and causing significant increase in volume (bulking). i • Settling areas in the storm drain inlets are provided to catch the water transported sand. The concrete lined ditches and settling areas must be cleaned as needed after storms. • The small sand grain size should ensure that any wind deposited material deposited in the ditches between storms will be flushed out at the beginning of the next storm. Nuisance Water Disposal Nuisance water is defined as silt and contaminant - carrying runoff from landscape irrigation and the debris and contaminants flushed from pavement surfaces during the first minutes of storm runoff. It does not include runoff from undeveloped areas. All storm drainage from the onsite and offsite areas is collected in the streets and storm drain system, and flows to distribution boxes in the bottom of the retention basins. The distribution box provides flexibility in connecting 4 MDS 69400 8/22/2007 ' deep storm drains to the retention basins without unnecessarily increasing the retention basin depth. Retention Basin depth must be minimized for aesthetic, safety, maintenance, construction and hydraulic efficiency reasons. Large storm flows that exceed the capacity of the Nuisance Water Disposal System (NWDS) will flow out through the top grates of these boxes, spread over the bottom of the retention basins, and percolate into the bottom and sides of each basin to the extent possible. Nuisance water flows smaller than the capacity of the NWDS will follow the same flowpath but will flow from the distribution boxes through small diameter (6inch) pipes to the NWDS, to be clarified and percolated into the ground beneath the bottom of the retention basin. A small lateral pipe (6 inch) may connect two or more distribution boxes to a single NWDS. The NWDS is designed per COLQ and the manufacturers requirements to collect nuisance water from hard surface and landscaped areas, remove debris and floating contaminants and dispose of the clarified water using ' Maxwell Plus percolation drywells in the bottoms of the basins. The Maxwell Plus and Maxwell IV systems are sized per COLQ and Torrant Industries standards. Percolation testing is not required for sizing of the systems when disposing of only Nuisance water. 5 Tab 3 Summary of Results 1. Design Criteria 2. Design Storms Precipitation Table 3.

(See Tab 3, Summary 6) • Storm drain HGL10 and HGL100 calculations shall be based on the Time of concentration (Tc), rainfall Intensity (I), and resultant peak flow (Q) in each pipe reach as adjusted for confluence Time of Concentration (Tc) differences using the Riverside County Rational Hydrology Method. • Drainage inlets, catch basins, and their lateral pipes shall be designed for the Q100 resulting from the Rational Method Tc and I at the individual inlet, not for the adjacent main line Tc & I. • NOTE Except at the most upstream inlets, the inlet and lateral Tc will be smaller, and the resultant I and Q used to size the inlet/lateral will be larger, than for the main line inflow from the inlet used in sizing the main line pipe.) • NOTE: Storm Drain design flow downstream of junction points will be less than the sum of the upstream main line and lateral design flows due to the differences in Tc and I of the main and lateral inflows at the junction described above. • All street inlets shall be curb opening without grates. • Inlets shall be placed at low points (sump) wherever possible. Maximum spacing shall be 1200 feet. • The 100 yr design storm water surface inside curb inlets shall be a minimum of 1.0 foot below the normal gutter flow line at the inlet. (1 foot of freeboard). • Curb depressions shall be 4 inch at all inlets, unless revised by the COLQ. • Per COLQ staff decisions, individual Curb depression detail drawings are not required on the improvement plans. TC elevations at each end of each Curb Inlet are required on the Street Improvement Plans • Sump inlets shall be sized for complete interception of the 100 -year design storm street flows. • Flowby inlets shall be sized to intercept 85 % or more of the street flow. • A Dedicated overflow outfall route and elevation shall be determined for all sump locations, with at least 1.0 ft of freeboard between the overflow water surface and any building pad. • The Historic Drainage Relief route along the Washington St curb at the south -east corner of Tract 35060 (approximate elevation 58.3) and thence east along the Historic Avenue 48 Drainage Relief route will be preserved as the Designated drainage relief route from Retention Basin # 1 (South). m= m r m m == m m == m m = == i MDS 69400 11- Jun -07 Summa, nr 2 - Storm,Precipitation; Volume Tract 35060 {Storm Volumes - .Rainfall Total during storm Per COLCQ Exhibit 4A- A.ttached Recurrance 2 Year 100 Year Storm Duration (inch) (inch) 1 Hour 0.50 2.20 3 Hour 0.70 2.80 6 Hour 1.00 3.40 24 Hour 1.60 4.50 :(us in Unit ed .H dro ra y. g p h Calculations un Summalry 3 - Drainage Area ` -- Hydrologic Soil Glloup•= Runoff Index Tract 35060 -� ;Hydrologic Soil Groups:A 8'B per..USDA- Soil Conservation Service= Rl;per Riverside County Hydrol Manual -1978 Drain Area A;?

' MAXWELL" PLUS DRAINAGE SYSTEM DETAIL AND SPECIFICATIONS CALCULATING MAXWELL PLUS REQUIREMENTS: The type of property, soil permeability, rainfall intensity and local drainage ordinances determine the number and design of MaxWell Systems. For general applications draining retained storm water, use one standard Maxwell Plus per the iti tmdtions below for up to 5 acres of landscaped contributory area, and up'to 2 acres of paved surface. ' To drain nuisance water flows in storm runoff systems, add a remote Wet to the Sgstem. For smaller drainage needs, refer to our Type IV MaxWeu For industrial drainage, our EndbreSo" may be recommended. For additional considerations, please refer to 'Design Suggestions For Retention And Drainage Sgstcurs" or consult our Design Staff. COMPLETiNGTHE MAXWELL PLUS DRAWING To apply the MmrWelf Plus drawing to your specific project, simply fill in the blue boxes per the following instructions. For assistance, please consult our Design Staff. #� 14�f L� PRIMARY SETTLING CHAMBER DEPTH BOLTED RING 5 GRATE /COYER The overall depth of the Primary Settling Chamber is determined by the amount of surface area being drained. Use a standard depth of 10 feet for the initial acre. of contributory drainage area, plus 2 feet for each additional acre, up to the design limits of the property type noted in "Calculating MaxWell Plus Requirements" noted above. Other conditions that would require increased chamber depths are property usage, maintenance scheduling, and severe or unusual service conditions. Connecting Pipe Depth may dictate deeper chambers so as to maintain the effectiveness of the settling process. ESTIMATED TOTAL DEPTH ( 20 f / 0 The Estimated Total Depth is the approximate total system depth required to achieve 10 continuous feet of penetration into permeable soils, based upon' known soil information. Torrent's specialized "crowd" equipped rigs get through the difficult cemented soils to reach dean drainage soils at depths up to 189 feet and their extensive drilling log database is available to use as a reference. SETTLING CHAMBER DEPTH On MfaxWell Plus Systems of over 30 feet overall depth and up to 0.25cfs design . rate, the standard Settling Chamber Depth is 18 feet. 13 �� D OVERFLOW HEIGHT The Overflow Height and Settling Chamber Depth determine the effectiveness of the settling process. The higher the overflow pipe, the deeper the chamber, the greater the settling capacity. An overflow height of 13 feet Is used with the standard settling chamber depth of 18 feet. & -Ff- O DRAINAGE PIPE This dimension also applies to the Prueflo" Debris Shields, the flofosf" Drainage Screen, and fittings. The size is based upon system design rates, multiple primary settling chambers, soil conditions, and need for adequate venting. Choices are 6" a" or 12" diameter. Refer to our company's "Design Suggestions for Retention and Orabage Systems" for recommendations on which size best matches your application. Standard models are quality cast iron and available to fit 24" 0 or 30" 0 manhole openings. All units are bolted in two locations with wording "Storm Water Only" In raised letters. For other surface treatments, please refer to "Design Suggestions for Retention and Drainage Systems." O INLET PIPE INVERT Pipes'up to 24" in diameter from catch basins, underground storage, etc. may be connected into the primary settling chamber. Inverts deeper than 4 feet will require additional depth in both system settling chambers to maintain respective effective settling capacities. C� INTAKE INLET HEIGHT The Intake Inlet Height determines the effectiveness of the settling process to the Primary Settling Chamber. A minimum inlet height of G feet is used with the standard primary settling chamber depth of 10 feet. Greater inlet heights would be required with increased system demands as noted in Primary Settling Chamber Depth. CHAMBER SEPARATION The standard separation between chambers is 1S feet from centerto center for inlet pipe inverts up to 7 feet. For deep inlet pipes or underground storage systems that result in a deeper Connector Pipe, add 5 feet of separation for each 3 feet of additional Connector Pipe depth. Maximum Connector Pipe depths and Chamber separations are 13 feet and 25 feet, respectively. A pump and Hit station is recommended for systems with deeper requirements. ' MAXWELL..

Site Description The site location is shown on the attached Figure 1. The parcel is located within: the SE 1%4 of the SWIA of Section 30; TSS, R7E of the San. Bernardino Baseline and Meridian. The proposed retention basins are to be constructed along the east. side of the development, parallel to Washington Street with the bottom elevations at 50 feet, or approximately 5 feet below existing grade.. ' The project site presently consists of a graded gravel parking lot with landscaped islands and paved. access roads. ' The. site- is. situated on sloping to nearly level ground that drains by sheet flow to. the. southeast. INovember 22, 2006 -2- File No. 06990 -07 Soil Conditions The field exploration indicates that site soils consist generally of Sil ty (Unified.

Free groundwater was The attached boring logs include detailed descriptions. of the soils encountered. Infiltration Testing The purpose. of the infiltration testing. was to measure: the ultimate infiltration rate to be used (with an appropriate factor of safety) in the design. of the: storm water. retention basins. The approximate locations of the tests: are. shown'on� the,attached: Figure 2:. Four exploratory borings were drilled in the vicinity of the proposed retention basins to depths of approximately: 20': feet. In addition, four infiltration test borings::were. drilled next to the. exploratory borings to depths of approximately 8' feet below the existing ground surface,.1 &6t below-* the proposed. depth .of the basins. The borings were drilled' on November 8, 20.06 using: an 8 -inch outside diameter hollow =stem auger, powered by a Simco 2800 HT truck- mounted drilling rig. A 3%4 -inch diameter perforated pipe.was set in each borehole. and the.annuluI&was backfilled.with pea =sized gravel. The testing was accomplished on November 8 and 9, 2006, and was completed according to the guidelines of the U.S: Bureau of Reclamation Method for Unsaturated Soils above Groundwater. The water. head was maintained at approximately 3 feet above the bottom of the test boring in order to test the zone 3 feet below the bottom of the proposed basin.

Maintenance of the retention basin is crucial' if no factor of safety is applied. Maintenance may include periodic scarifying the bottom of basin to open soil pores- clogged by siltation, oils,. or vegetation growth. A silt and oil trap placed at influent points may be considered to reduce the potential for reduction in the infiltration rate of soils.

Land' use should be based on ultimate development of the watershed. Long range master plans for the County and-incorporated cities should.be reviewed to insure reasonable land use assumptions. 2. Recommended values are based on average conditions which- may' not apply to a, particular study area. The percentage impervious -may vary greatly even on comparable sized lots due to differences in. dweling.s.ize, improvements, etc. Landscape practices should also be considered as it is. common in some areas to use ornamental grav- els underlain. by impervious plastic materials in place of lawns and shrubs. Afield investigation of a study area should always be made, . and a review of aerial photos, where available may assist in estimat -- ing the percentage of impervious cover in.-developed areas. 3..For typical horse. ranch subdivisions increase impervious area S per - cent over the values recommended in the table.above.
