(dba Berryman & Henigar, Inc.) is pleased to submit this Baseline Avenue Sewer Study Report. This report will provide the City of Fontana with the necessary information to make decisions on the installation of new sewer facilities as well as related sewer upgrades in the subject area. If you have any questions regarding this sewer study, please feel free to call me. Sincerely, Mohammed Rowther, P. E.

The project area is bound by Citrus Avenue and the City limits (Palmetto Avenue) in the east -west direction; and South Highland and Baseline Avenues in the north -south direction. The purpose of this study is to identify and propose new facilities in these streets based on City's Sewer Master Plan flow projection rates at build -out. The City has also requested Berryman & Henigar to determine whether the existing sewer facilities within the project limits are able to accommodate sewer flows at build -out. Recommendations will be made to upgrade the existing sewer system if necessary. This letter report will provide the information to allow the City to make the necessary improvement decisions Evaluation Criteria and Methodology According to City's most recent land use designations, the project study area is comprised of three land use (LU) categories, single-family residential (R -SF), general commercial (C -G), and public facility (P -PF). The City's Master Sewer Plan Update (September 2000) designated sewage flow generation factors in relation to all land use categories. Exhibit A presents the City's Sewage Generation Factors in tabular format. Table 1 summarizes the relevant generation rates corresponding to the project land use designations. Tahle 1 - Sewaae Flow Generation Rates within Prniert I imits Land Use Equivalent DU/Acre Flow Per DU Flow allons/da per Acre R -SF 5.00 279 1395 C -G 5.38 _ 1500 P -PF _ 5.38 1500 The proposed sewer main sizes were determined based on the City's peak daily flow (PDF) calculation formula shown below: PDF = 2.5(Qm9,)o ' Where Qmgd is the average daily flow (ADF) expressed in million gallons per day (mgd). All proposed sewers presented in this report meet the City's design requirements in term of 1 Minimum pipe slope between manholes of one percent (1%) 2 Minimum pipe size of 8 inches 3. Minimum pipe depth of 8 feet 4. Minimum flow velocity of 2.5 feel per second (fps) 5. Maximum spacing between each manhole is 350 feet 6. Depth of flow to depth of pipe diameter ratio (D/d) must be less than 0.50 for main diameters less than 12 inches; and 0.75 for pipe diameters greater than 12 inches 7. All sewer main will be vitrified clay pipe (VCP) using a Manning's 'N' value of 0.013 Sewer System Evaluation The general flow pattern follows the natural drainage topography. The proposed system is designed to direct flow towards the south/southwesterly corner of the project site. Drainage basins are divided among streets aligned in the north/south direction. Once the flow reaches the junctions at the southern limits, the flow continues westerly connecting into an existing 18 -inch vitrified clay pipe (VCP) at the intersection of Citrus and Baseline Avenue. A tabular summary of flow calculations based on land use is shown in Exhibit B. A graphical illustration of the recommendation is shown in Exhibit C. Citrus Avenue It is estimated the flow generated north of Highway 30/210 is approximately 6 mgd (See Exhibit D). Part of the tributary flow from the north will be directed into a system on Citrus Avenue via an existing 21" VCP At the intersection of Citrus and Los Cedros Avenue, the 21" VCP bends and directs flow westerly. The proposed 8" VCP on Walnut Avenue, east of Citrus, will be directed southward connecting into an existing 15 -inch VCP on Citrus Avenue. While the existing 15" VCP on Citrus Avenue is over designed, it is not necessary to replace the existing sewer system. Oleander, Cypress, and Juniper Avenues Based on review of the current system, the existing 8 -inch VCP system along Oleander Avenue south of Walnut Street is able to accommodate the projected volume only if flow east of Oleander is diverted into a new drainage basin on Cypress. It is recommended that the new facilities on Cypress Avenue south of Walnut Street be 10 inches in diameter. Existing flow generated along Sierra Avenue entering the Juniper basin will be directed into an existing 8 -inch VCP south of Baseline Avenue. The proposed 8 -inch collection system on Juniper north of Baseline will be conveyed westerly into the proposed 10 -inch VCP on Baseline Avenue. Mango and Sierra Avenues With the exception � of seven parcels east of Sierra and an approximate 147.5 AC west of Palmetto Ave, all other residential discharge between Sierra and Mango Avenues will flow easterly towards an existing 8 -inch VCP system on Mango Avenue. At build out, it is recommended the existing 8 -inch VCP south of MiCallef Street be upgraded to a 12 -inch VCP. The projected flow west of Sierra Avenue will require an 8 -inch VCP system to be installed connecting into an existing 8 -inch main near the southern end of Sierra Avenue. Baseline Avenue As indicated in Exhibit C, 18 -inch, 15 -inch, and 10 -inch VCPs are recommended along Baseline Avenue to convey flow westerly into an existing 18 -inch VCP at the intersection of Citrus and Baseline Avenue. An 8 -inch VCP collecting flow between Sierra and Mango Avenues along Baseline is recommended to direct flow easterly. For future development along the northwestern side of Baseline and Palmetto Avenue, another 8 -inch VCP collecting flow between Mango and Palmetto Avenues along Baseline is recommended to direct flow easterly toward Palmetto Avenue. All flows currently flowing southerly past Baseline Avenue will be diverted westerly towards Citrus Avenue. Summary of Recommendations Shown below is a summary of the improvements to be made on each street within the project area: ♦ Citrus Avenue o 1500 linear feel of 8 inch VCP o 4 new manholes ♦ Oleander Avenue c 600 linear feel of 8 inch VCP o 2 new manholes Cypress Avenue 600 linear feet of 8 inch VCP 0 2,650 linear feet of 10 inch VCP o 9 new manholes ♦ Juniper Avenue o 3,000 linear feet of 8 inch VCP o 9 new manholes • Sierra Avenue o 3,200 linear feel of 8 inch VCP o 11 new manholes ♦ Mango Avenue 0 1,300 linear feel of 12 inch VCP upgrade ♦ South Highland Avenue 0 2,450 linear feet of 8 inch VCP 0 7 new manholes • Walnut Street 1,900 linear feet of 8 inch VCP u Abandon 270 linear feet of 10" VCP c, 6 new manholes • Baseline Avenue c 1500 linear feet of 8 inch VCP 0 1,320 linear feet of 10 inch VCP 0 1,320 linear feet of 15 inch VCP n 1,400 linear feet of 18 inch VCP o 18 new manholes Exhibit B - BASELINE AVENUE SEWER STUDY (CITRUS TO CITY LIMITS) Citrus Avenue (North of Walnut)- 'Based on City of Fontana's Sewer Master Plan (1998), Flow from Tributary Area North of Highland Avenue is Approximately 6 MGD.
