The Design-Builder is responsible for ensuring that design and construction of all improvements complies with all laws, codes, and regulations applicable to local detention facilities and that all systems are complete, integrated, cohesive and functional for their intended purposes. The Design-Builder shall provide detailed calculations and design documentation for all systems prior to construction and submit for review by the applicable Authority Having Jurisdiction (AHJ). Performance criteria identify minimum levels of quality, materials, and workmanship. Codes & Standards: The site grading and drainage, pedestrian and vehicle circulation, and site utility design of the project shall be based on but not limited to the following codes and standards: 2016 California Building Code (CBC), California Code of Regulation, Title 24, Part 2-Volumes 1 and 2 as amended therein. 2016 California Green Building Standards Code (CalGreen), California Code of Regulation, Title 24, Part 11 as amended therein. 2016 California Plumbing Code (CPC), California Code of Regulation, Title 24, Part 5 as amended therein. 2016 California Fire Code (CFC), California Code of Regulation, Title 24, Part 9 as amended therein and as amended by local ordinance.

Items not covered herein and in the above documents shall conform to the applicable provisions of the applicable City of Santa Paula and Ventura County Construction Standards, City of Santa Paula Fire Department informational bulletins, municipal codes, council resolutions and ordinances. Public sewer or water mains, if any, may be required to be designed in accordance with City of Santa Paula Design and Construction Standards. BASIS OF DESIGN: Surface Drainage: The existing topography sheet flows at an easterly direction. Off-site runoff from the agricultural farmland is intercepted by a drainage channel along the edge of the existing access road. With the addition of the 63,000-square foot building, the access road and channel will be realigned to the north to circumvent the new footprint. In between the proposed building and the existing parking lot to the west, there is an existing concrete gutter that will be cut-off by a proposed corridor on the south side of the building, connecting to an existing structure. The gutter has a tributary area of about 0.8-acre, upstream of the corridor. This drainage area will be re-routed around the building through a new concrete ribbon gutter with a very minimal longitudinal slope (0.0028 ft./ft.). This proposed ribbon gutter will act as the main storm water conveyance, collecting and conveying runoff from the entire westerly side of the site, including roof drains. Storm water runoff generated within the project limits, including all impervious areas, roof drains, and developed pervious areas, shall be captured and conveyed towards appropriate Best Management Practices (BMPs) for infiltration and/or treatment, prior to discharging off-site, to the maximum extent practicable. The realigned access road will have a super- elevated cross slope that allows runoff to drain on-site to allow for treatment. By intercepting runoff from the agricultural area, commingling of off-site and on-site flows is avoided, eliminating the requirement to treat the off-site runoff as well. An exception will be the 0.8-acre drainage area on the westerly side of the project that will be re-routed around the building. Runoff generated from this area will need to be accounted for in the BMP sizing, along with the rest of the on-site drainage. Initial peak flow calculations for the existing and proposed conditions utilized the Ventura County Watershed Protection District’s Time of Page 2 Ventura County Todd Road Jail Sheriff’s Office Health and Programming Unit April 23, 2018 Volume 2A SCOPE OF CONSTRUCTION – CIVIL Concentration Calculator and the VCRat 2.6 program. With the preliminary grading concept increasing the overland flow path on the westerly side of the project, the time of concentration - defined as the time required for runoff to travel from the hydraulically most distant point of a watershed to its outlet - increased in the proposed condition. This resulted in a reduction of peak flows compared to the existing condition, offsetting the increase in impervious area. Consequently, mitigation (i.e. detention) will not be required to minimize the impacts of development on the existing drainage system. Storm Water BMPs: To mitigate the potential water quality impacts, Best Management Practices will be implemented to reduce the hydrologic and water quality impacts associated with the development, as described in the 2011 Ventura County Technical Guidance Manual (TGM), Errata Update 2015, and the Ventura County Municipal Storm Water Permit (Order 2010-0108). Additionally, a Post Construction Storm Water Management Plan (PCSMP) will need to be prepared for the project, which specifies the storm water quality mitigation employed and its proper sizing. The document will also include a Storm Water Treatment Device Access and Maintenance Agreement, and a Maintenance Plan. For the construction phase, a Storm Water Pollution Prevention Plan (SWPPP) and Erosion Control Plan are required. These documents specify how a construction project will minimize storm water pollution through the application of appropriate temporary BMPs. SWPPPs are designed to comply with California’s General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities and issued by the State Water Resources Control Board. Referencing the Geotechnical Data Report (Fugro USA Land, Inc. Project No. 04.62160076_R1, dated January 13, 2017), low percolation rates, clayey layers beneath the potential basin locations, and a ground water elevation of about 8 ft. below existing grade, there is adequate information to assert technical infeasibility of storm water infiltration. Therefore, a biofiltration BMP will be used and sized to treat 1.5 times the Storm Water Quality Design Flow not retained using Retention BMPs. If further investigation is conducted in the design phase that shows otherwise, then an infiltration BMP should be constructed. The proposed BMP is a vegetated swale for biofiltration treatment and release.
