1. INTRODUCTION
This report presents a summary of the hydrology and hydraulic studies perform for the proposed Calimesa Channel Storm Drain Improvement “Stage III” (Project). The improvements will take place along the Calimesa Channel storm drain system, one of the five mayor flood control systems traversing the City of Calimesa (City) predominantly in the Southwest direction, all of them been tributary to San Timoteo Creek, a mayor tributary of the upper Santa Ana River. The proposed Project is located on the east side of the Interstate 10 between Avenue H (City of Yucaipa) to the north and Avenue L (City of Calimesa) to the south, in T2S, R2W in Riverside County and has a tributary watershed of 823 acres. The Project is sponsored by the City and the Riverside County Flood Control and Water Conservation District (RCFC&WCD).

2. PROJECT DESCRIPTION
The Project is situated in the proposed Downtown Business District (DBD) in the City and runs along the boundary between Riverside and San Bernardino Counties, and between the City and City of Yucaipa; see Exhibit 1 – Vicinity Map. The proposed Project is considered a continuation of the Calimesa Channel “Stage I” project completed by the RCFC&WCD (Project No. 5-10-160) and is a component of an ultimate storm drain system that will provide 100-year flood protection to existing developments along County Line Road, surrounding the Calimesa DBD.

Calimesa Channel “Stage I” and “Stage II” consists of a concrete lined trapezoidal channel beginning at County Line Road, approximately 500 feet west of California Street. The existing trapezoidal channel, with a base width of 4 feet and a depth of 5 feet, meanders westerly through existing residential neighborhoods and outlets on the west side of 5th Street. Thereafter, the Calimesa Creek is an unimproved earthen channel that continues meandering westerly through the City’s DBD, to near Interstate 10 (I-10) Freeway where an improved storm drain system carried flow under the freeway. Following is again an unimproved earthen channel that continues meandering westerly and southwesterly to the San Timoteo Creek.

The proposed Project (Calimesa Channel “Stage III”) consists of a detention basin and a storm drain system to provide 100-year flood protection. The proposed detention basin is adjacent to the existing Calimesa Channel “Stage I”, approximately 200 linear feet (LF) west of 3rd Street. The proposed storm drain system consists of approximately 312 linear feet (LF) of 78 inch diameter reinforced concrete pipe (RCP), 1,630 LF of 72 inch diameter RCP, 170 LF of 6 foot x 6 foot reinforced concrete box (RCB), 60 LF of RCB to trapezoidal channel transition, with associated catch basins and connector pipes. The Project is sized to convey the ultimate develop condition, 100-year storm flow for the Calimesa Channel watershed upstream from the existing storm drain system at I-10 Freeway; see Exhibit 4, Nodes 99 and 98.

3. PURPOSE
The purpose of this study is to determine the 100-year peak flow rates and hydrograph volumes from the drainages areas tributary to the Project site for both the existing and ultimate developed condition. In addition, this study will confirm detention basin sizing required to reduce the ultimate developed condition peak flows to be manageable within existing storm drain facilities near I-10 and downstream the Project.

4. HYDROLOGY

4.1 Methodology
For this analysis, both the Rational Method and the Unit Hydrograph Method were used.

According to Riverside County Flood Control and Water Conservation District Hydrology Manual, published in 1978 (Hydrology Manual), the Rational Method is to be used for drainage areas smaller than 300 to 500 acres, and the Unit Hydrograph Method is to be used for areas larger than 300 to 500 acres. In this study, it was decided to use 500 acres as an approximate (more conservative) break point to switch from the Rational Method to the Unit Hydrograph method to estimate the peak flow rates.

The AES RATSC hydrology model has the ability to switch between these two peak flow estimation methods using one data base of hydrologic information. The computer model has an internal bookkeeping system which develops the area-average values of the loss rate, low loss rate fraction and rainfall depths for the Unit Hydrograph analysis. The time of concentration (Tc) of the longest flow path is used in the Unit Hydrograph lag estimation. If the total tributary area at any concentration point is greater than 500 acres and the time of concentration (Tc) is greater than 12.5 minutes, the hydrologic analysis can then be switched from Rational Method to the Unit Hydrograph Method without leaving the computer model.

The Rational Method modeling approach is widely used due to the simplicity in application, and the capability for estimating peak runoff rates throughout the study watershed. The Unit Hydrograph Method was used to develop peak flow rates for drainage area greater than 500 acres. The unit Hydrograph lag time is calculated as (0.8) Tc, where Tc is the Rational Method time of concentration for the longest flow path. In the Unit Hydrograph study, the “Valley” S-graph was used.

For the Existing Condition, the AES RATSC hydrology model was used to calculate peak flow rates, as described above, see Appendix B.1. For the Ultimate Developed Condition, single area Unit Hydrographs were developed to calculate peak flow rates using the U.S. Army Corp of Engineers (USACE) “Empirical Formula”, AES software was designed to accept watershed data and to perform synthetic unit hydrograph method analyses in accordance with the Hydrology Manual. This process ensures all sub-areas are included in the hydrology analysis; whereas with just AES, smaller areas after a confluence (or basin routing in this case) may not be applied to the overall flow analysis. In addition, this method defines the study area by the distance of the longest flow path, tributary area, centroid location and area loss rate; as shown in Exhibit 3.

4.2 Topography and Drainage Boundaries
Hydrologic boundaries for the Existing and Ultimate Developed Conditions were based on the existing topographic conditions that were created either by natural causes or by the effect of the City’s urbanization, see Exhibit 2. Elevation data for the Calimesa Channel “Stage III” was obtain from a field survey performed by TKE Engineering for the roadway and existing creek between I-10 Freeway and 5th Street, and for the basin site near 3rd Street. Additional elevation data was taken from other TKE Engineering field surveys performed for the City, Calimesa Channel “Stage I” and “Stage II” plan set, and online Digital Elevation Model (DEM) with data collected by NASA’s Shuttle Radar Topography Mission (SRTM). Note, a correction factor was applied to this last data source to match field survey datum.

4.3 Land use and Zoning
Land use and zoning within the Calimesa Channel “Stage III” watershed is based on review of the existing development patterns, field reconnaissance, aerial photos, assessor’s parcel data, the City’s General Plan, and the City of Yucaipa’s General Plan. Undeveloped parcels were assumed to be developed for the Ultimate Developed Condition analysis, based on the land use designations consistent with both Cities general plans and existing development patterns.

4.4 Soil Type Designations
The underlying hydrologic soil groups are Types A, B, C, and D as shown on the RCFC&WCD Hydrology Manual Plate C-1.06 and on the San Bernardino County Flood Control District Hydrology Manual Figure C-16.

4.5 Rainfall
The precipitation depth used in the AES RATSC hydrology model were based on those reported on the RCFC&WCD Hydrology Manual, see Plates E-5.2, E-5.4 and E-5.6, for the 100-year storm event for 3-hour, 6-hour and 24-hour durations, respectively. Per the RCFC&WCD Hydrology Manual, all three durations were analyzed, see Section 5 for additional information.

4.6 Ground Cover
The undeveloped ground cover consists of natural covers including native grasses and broadleaf chaparral in fair condition with runoff index numbers per the RCFC&WCD Hydrology Manual Plate E-6.1. The developed condition ground cover consists of landscaping over pervious areas as well as impervious surfaces consisting of roofs, sidewalks, driveways, and roadways. The percent of impervious area is based on the recommended percentages stated in the RCFC&WCD Hydrology Manual Plate E-6.3.

4.7 Loss Rates
Loss rates for the Existing and Ultimate Developed Conditions were calculated based on the RCFC&WCD Hydrology Manual procedures. Existing Condition data input computed (AES RATSC hydrology model) based on the weighted average of soil type and ground cover components of each watershed. Ultimate Developed Condition used similar methods as presented in the RCFC&WCD Hydrology Manual (Plate E-2.1), see Appendix B.4, but included impervious areas based on proposed developments plans.

4.8 Drainage Pattern/Mapping
As mention before, the Calimesa Creek system, east of I-10 Freeway, has a tributary watershed area of 823 acres. The existing storm flows travel mainly on the east to west and southwest direction, starting from most upstream areas located at the City’s eastern boundary and adjacent to the San Bernardino National Forest.

The primary stream originates in the City of Yucaipa on Mesa Grande Drive (Exhibit 2, Node 1806), then along County Line Road where storm flows are conveyed through the street. As flows approach Bryant Street, they are combined with flows traveling on the Southwest direction coming from a natural earthen channel (Exhibit 2, Node 114). From this confluence point, flows continue to travel in the east to west direction along County Line Road on a combination of street flow with an unimproved channel running parallel and street flow with a pipe running parallel up to California Street. At California Street, flows are conveyed through two 42 inch RCPs up to 530 LF west to the beginning of the existing improved trapezoidal concrete-lined channel (Calimesa Channel “Stage II”) (Exhibit 2, Node 111). The Calimesa Channel “Stage II” and “Stage I” carries storm flow, picking up additional flows at 2nd Street (Exhibit 2, Node 109), 3rd Street (Exhibit 2, Node 107), 4th Street (Exhibit 2, Node 106), and 5th Street (Exhibit 2, Node 105), to west of 5th Street (Exhibit 2, Node 104).

From California Street to 5th Street and north of County Line Road, storm runoff travels on the east to west direction predominantly as sheet flows, until they intersect and flow into the north to south streets (2nd Street, 3rd Street, 4th Street, and 5th Street). Flows then travel south to County Line Road, where they are collected via drop inlets or catch basins and then conveyed to the existing improved Calimesa Channel, as described above.

From 5th Street, the unimproved earthen channel (Calimesa Creek) continues to convey flows westerly, picking up additional flows at Calimesa Boulevard (Exhibit 2, Node 101), to near I-10 Freeway where an improved storm drain system carries flows under the freeway (Exhibit 2, Node 99).

The proposed Project will join the existing trapezoidal channel, near 5th Street (Exhibit 3, Node 104) and transition from a trapezoidal channel to a 6 foot x 6 foot RCB.

Subsequently, the RCB continues northwest toward County Line Road (Exhibit 3, Node 994) were a low-flow diversion structure will send a portion of flows to the existing Calimesa Creek (Exhibit 4, from Node 994 to Node 997 to Node 996). The remaining flows, including 100-year flows, will continue northwest toward County Line Road, transitioning to a 72 inch RCP (Exhibit 3, at Node 993). From there, the 72 inch RCP will convey flows westerly along

County Line Road to Calimesa Boulevard, picking up additional flow at Nodes 992 and 991 (See Exhibit 3). After this confluence, a 78 inch RCP will convey flows along County Line Road westerly, then curve southwesterly to connect to the existing the 78 inch RCP (Exhibit 3, Node 99).

The end of the proposed Project (Calimesa Channel “Stage III”) connects to an existing 78 inch RCP that crosses beneath a parking lot, then confluences with storm flows from the Avenue L Storm Drain System (RCFC&WCD Project No. 5-0-0165); see Exhibit 4, Node 98.

This is the concentration point for two watersheds: Calimesa Avenue L watershed and the Calimesa Creek watershed. This confluence sump is the inlet for the existing 6 foot x 6 foot RCB that conveys flows under I-10 Freeway then into the existing natural drainage channel then ultimately flows to San Timoteo Creek.

5. RESULTS

5.1 Storm Drain Hydraulic Model
A hydraulic model for the existing 78 inch RCP at the downstream end of the proposed Project was develop using CivilDesign’s Water Surface and Pressure Gradient Hydraulic Analysis program (WSPG). The hydraulic model was run for the Ultimate Developed Condition 100-year storm flow and can be found in Appendix C.1. Based on the rating table of the existing 6 foot x 6 foot RCB under I-10 Freeway (see Calimesa-Avenue L Storm Drain Project No. 5-0-0165 Appendix E.4), the maximum flow rate “due to its limited hydraulic capacity” is 690 cubic feet per second (cfs) with water surface elevation of 13.64 feet above pipe flowline when the sump is “full”, prior to overflowing onto the I-10 off ramps and County Line Road. In order to have consistent analysis with Calimesa-Avenue L Storm Drain calculations, a hydraulic grade line (HGL) with a maximum water surface elevation of 2,372.77 feet (Existing 108” RCP Flow Line = 2,359.13 feet + 13.64 feet) was used as the starting water surface elevation for the WSPG modeling.

5.2 Hydrology/Hydraulics: Existing Developed Condition
The general drainage pattern and distribution of flows for the existing condition was described in Section 4.8 and is shown on Exhibit 2. A summary of peak flows for the three rainfall events is presented in Table 1 below. Since the 3-hour rainfall event generated the highest peak flow rates, it was selected as the governing existing condition hydrology; see the full hydrology report in Appendix B.1. Starting at 5th Street (Exhibit 2, Node 104), there is a 100-year tributary runoff of 1,043 cfs coming from the existing trapezoidal channel, with a portion of the top 1.0 feet of free board being used under this storm event. The channel then widens and transitions to earthen channel through ungrouted rip-rap. Flows continue traveling west though a winding earthen channel, with vegetation growth. The 100-year tributary runoff of 1,043 cfs is kept within the most critical cross section of the existing creek before the culvert crossing at Park Avenue (Exhibit 2, Node 103). The Park Avenue crossing consists of an existing 54” corrugated metal pipe (CMP). The 54” CMP can convey a 100-year storm flow of 217 cfs with a maximum channel elevation of 2,418.00 feet. Therefore, the Park Avenue crossing is critically deficient in managing 100-year tributary runoff of 1,043 cfs, see culvert analysis in Appendix C.2. In a 100-year storm

event, storm flows (approximately 817 cfs) would backup behind the Park Avenue crossing and eventually overflow onto Park Avenue and County Line Road. Of note, the City has experienced flooding at the Fire Station and City Hall approximately 150 feet south of said crossing during even moderate storm event.

99 823 1,047 920 604
After Park Avenue culvert crossing (Exhibit 2, Node 102), it is assumed that a majority of the overflows will be redirected back in to Calimesa Creek, and continue flowing westerly though the existing earthen channel with vegetation and tree growth at the base and walls of the channel. The 100-year tributary runoff of 1,043 cfs is again kept within the most critical cross section of the existing creek before the culvert crossing at Calimesa Boulevard (Exhibit 2, Node 101). Here, the existing flows confluence with stream flows from both the north and south, for a peak flow runoff of 1,051 cfs after confluence. The Calimesa Boulevard crossing consists of an existing 6 foot x 6 foot RCB and can convey a 100-year storm flow of 403 cfs with a maximum channel elevation of 2,391.50 feet. Therefore, the Calimesa Boulevard crossing is critically deficient in managing 100-year tributary runoff of 1,051 cfs, see culvert analysis in Appendix C.3. In a 100-year storm event, storm flows (approximately 648 cfs) would backup behind the Calimesa Boulevard crossing and eventually overflowing onto private property and Calimesa Boulevard.

After Calimesa Boulevard culvert crossing (Exhibit 2, Node 100), it is assumed that a majority of the overflows will be redirected back in to Calimesa Creek, and continue flowing westerly though the existing earthen channel with vegetation and tree growth at the base and walls of the channel. The 100-year tributary runoff of 1,051 cfs is again kept within the most critical cross section of the existing creek before the downstream culvert inlet east of I-10 Freeway (Exhibit 2, Node 99). Here, the existing flows enter into the existing 78 inch RCP, discussed in Section 5.1. As described above, the existing 78 inch RCP can convey a 100-year storm flow of 754 cfs. Therefore, the 78 inch RCP is critically deficient in managing 100-year tributary runoff of 1,051 cfs, see culvert analysis in Appendix C.1. In a 100-year storm event, storm flows (approximately 297 cfs) would backup and eventually overflowing onto private property and County Line Road.

As described in Section 4.8, the 78 inch RCP cross beneath a parking lot (for Baker’s Restaurant) and outlets in to a sump (Exhibit 4, Node 98), where it confluences with storm flows from the Avenue L Storm Drain System. This sump drains to the existing 6 foot x 6 foot RCB that crosses under I-10 Freeway. Base on the RCFC&WCD’s sump analysis, the I10 Freeway culvert crossing is critically deficient in conveying the 100-year tributary runoff, causing overflow onto County Line Road and the I-10 Freeway underpass. Overflow runoff

would then travel west, through the existing roadway, and then south until draining back into the existing unimproved Calimesa Creek at 7th Place.

5.3 Hydrology/Hydraulics: Ultimate Developed Condition
The Ultimate Developed Condition is shown on Exhibit 3. The primary objective of the ultimate storm drain system is to provide 100-year flood protection within the existing Calimesa Creek watershed, with the greatest benefit along County Line Road and the City’s DBD. The general drainage pattern and distribution of flows for the proposed Project was described in Section 4.8. A summary of peak flows for the three rainfall events is presented in Table 2 below. Since the 3-hour rainfall event generated the highest peak flow rates, it was selected as the governing Ultimate Developed Condition hydrology; see the full hydrology report in Appendix B.2. East of 3rd Street, the Calimesa Channel “Stage I” 100- year flow rate of 811.48 cfs will be diverted into a detention basin (Exhibit 3, Node 1062).

The proposed 53 acre-foot detention basin will reduce 100-year flows leaving the basin to 375 cfs (Exhibit 3, Node 1061); see Section 5.4 for detailed basin routing analysis.

104 784 608 372 343
99 823 662 422 385
The reduced 100-year flows would continue down the existing trapezoidal channel to west of 5th Street (Exhibit 3, Node 104). There, the proposed Project will transition the 100-year flow rate of 608 cfs from the existing trapezoidal channel into a 6 foot x 6 foot RCB. Then, the RCB continues northwest toward County Line Road were a low-flow diversion structure will send a portion of flows to the existing Calimesa Creek (Exhibit 4, Node 994).

Approximately 60 cfs will be diverted back into the existing Calimesa Creek. The remaining 100-year flow rate of 547 cfs will continue northwest toward County Line Road, transitioning to a 72 inch RCP (Exhibit 4, at Node 993). From there, the 72 inch RCP will convey said flows westerly along County Line Road to Calimesa Boulevard. At Calimesa Boulevard, additional flows are picked up (Exhibit 4, Nodes 992 and 991), for a combined 100-year flow rate of 662 cfs. After this confluence, a 78 inch RCP will convey the 100-year flows along County Line Road westerly, then curve southwesterly to connect to the existing the 78 inch RCP (Exhibit 4, Node 99). The 100-year flow rate at the connection to the existing 78 inch RCP is 663 cfs. As described in Section 5.1, the existing 78 inch RCP (Calimesa-Avenue L Storm Drain Project No. 5-0-0165) can adequately convey up to 690 cfs with a water surface elevation of 13.64 feet above pipe flowline when the sump is “full”; therefore, it can convey the proposed Project flows downstream.

Of note, the proposed system was also modeled under the assumption that there was no low flow diversion (Exhibit 4, Node 994) to account for any potential blockage or issues with

the existing creek system or should the City elect to eliminate it entirely. Again, the 3-hour rainfall event generated the highest peak flow rates and was selected as the governing Ultimate Developed Condition hydrology with no low flow outlet (i.e. no flow split); see the full hydrology report in Appendix B.3. Under this scenario, the full 100-year flow rate of 607 cfs at Node 994 would continue down County Line Road to Calimesa Boulevard. At Calimesa Boulevard, additional flows are picked up (Exhibit 4, Nodes 992 and 991) for a combined 100-year flow rate of 662 cfs. After this confluence, a 78 inch RCP will convey the 100-year flows along County Line Road westerly, then curve southwesterly to connect to the existing the 78 inch RCP (Exhibit 4, Node 99). The 100-year flow rate, under this worst-case scenario, at the connection to the existing 78 inch RCP is 662 cfs; and as described in Section 5.1, the existing 78 inch RCP can adequately convey these flows downstream.

5.4 Detention Basin Routing
The hydrology computed for the Ultimate Drainage Condition was used in combination with the proposed detention basin properties to perform basin routing calculations; See Exhibit 3 for detailed basin routing. Basin storage properties are based on an area and depth for the proposed basin grading. Basin discharge through the low-flow outlet was based on inlet control analysis of the proposed dual 42 inch RCP outlets; see Appendix C.4. The basin data was entered into the AES Flood Routing Analysis downstream of the basin’s tributary inflow hydrograph. Basin outflows were then Channel Routed back into the existing channel to continue the routing process (Convex Method) downstream by combining additional subareas hydrographs up to the connection point at the existing 78” RCP (Exhibit 4, Node 99). A summary of the reservoir routing results for the three rainfall events is presented in Table 3 below. Since the 3-hour rainfall event generated the highest peak inflow, it was selected as the governing Ultimate Developed Condition hydrology; see the full hydrology report in Appendix B.2. The proposed detention basin will receive a peak inflow of 812 cfs and release a peak outflow of 375 cfs downstream. The peak flood volume through the basin is 86.96 acre-feet. Additionally, the peak water surface elevation is the basin is 2,478.73 feet, which is below the spillway crest elevation of 2,480 feet and the basin crest elevation of 2,482 feet. The proposed dual 42 inch RCP outflow can convey a 100-year storm flow of 428 cfs with a maximum basin elevation of 2,482 feet; see culvert analysis in Appendix C.4.

[1] The Basin Crest Elevation is 2,482 feet and the Spillway Crest Elevation is 2,480 feet. The basin has a total storage capacity of 53.1 Acre-Feet.

5.5 Proposed Storm Drain Hydraulics
The proposed Project includes three storm drain lines; the Mainline, Line A, and Line B. The Mainline consists of 6 foot x 6 foot RCB, 72 inch RCP, and 78 inch RCP. The Mainline hydraulic model and analysis can be found in Appendix D.1 and D.2, respectively. In addition, the Mainline hydraulic model and analysis was also run in the “no flow split” scenario and the results can be found in Appendix D.3 and D.4, respectively. Storm drain Line A consists of the 54 inch RCP in Calimesa Boulevard and its hydraulic model and analysis can be found in Appendix D.5 and D.6, respectively. Finally, Storm drain Line B consists of the 36 inch RCP low flow outlet and its hydraulic model and analysis can be found in Appendix D.7 and D.8, respectively. As shown in the analysis, all proposed storm drain facilities maintain an hydraulic grade line below the existing and/or proposed ground surface.

5.6 Project Impact
The net effect of the proposed Calimesa Channel “Stage III” is a decrease in the 100-year flow rate from 1,051 cfs in the Existing Condition to 662 cfs in the proposed Ultimate Condition (Exhibit 4, Node 99). The proposed Project with provide the following benefits:
 Reduce peak 100-year flow rate to downstream facilities,  Reduced storm drain infrastructure costs,
 Eliminating flooding at Park Avenue and Calimesa Boulevard,  Alleviate flooding along County Line Road and I-10 underpass, and  Provide flood protection for the Fire Station, City Hall, and DBD.

The proposed Project, the Calimesa Channel “Stage III”, is an important component of an ultimate storm drain system. However, in order to convey the 100-year runoff from both the Calimesa Creek watershed and the Avenue L watershed westerly across I-10 Freeway, the existing sump and 6 foot x 6 foot RCB would require additional modifications, replacement, or the construction of an additional drainage facility crossing the freeway as a component of a regional drainage plan. This would involve coordination among Caltrans, the City, the City of Yucaipa, RCFC&WCD, and San Bernardino County Flood Control District.

However, the proposed Project has significantly decreased the flooding potential by incorporating a detention basin. The detention basin reduced 100-year flow rates by over 380 cfs.
