Engineer's name, number, expiration date and signature included on all sheets? Instructions: This checklist provides advance notification to applicants of the City of Campbell's requirements for final on-site grading and drainage plans. Using this checklist will expedite your application through the City's review process. While this checklist summarizes major and typical topics of review, site specific issues can and will produce additional comments. Prior to submitting a final on-site grading and drainage plan, please place an in the box indicating that you have complied or that the particular item does not apply. This checklist references standard CAD sheets, benchmarks, and stormwater requirements that can be found on our website at: Project Address: Reviewer / Date: Rev. 04-10-20 Page 1 of 4 ---PAGE BREAK--- Engineering Checklist for On-Site Grading / Drainage / Stormwater / Site Improvement Plan Yes N/A ITEM OR DESCRIPTION Technical Requirements Reference to City Benchmark? (See website for list of benchmarks) Existing and proposed easement lines shown? If a subdivision, are proposed monuments shown to avoid conflict with proposed walls, fences, and other surface improvements? Please note that a Certificate of Correction will be required if monuments cannot be set in locations shown on the associated subdivision map due to field conflicts. Quantities of cut, fill, import and export shown on plan in cubic yards (CY)? Plan shows existing ground contours? Property limits shown? Spot elevations shown on-site? Spot elevations shown off-site, sufficient to allow assessment of potential stormwater impacts/runoff on adjacent properties? Proposed elevations at high points, grade breaks, and other significant locations? Flow lines, or at least top of curb elevations shown? Grades of paved areas > 1% for PCC and > 1.5% for AC? Grades within 10 feet of structure conform to Section 1804 of 2019 California Building Code (or latest adopted code)? slope for unpaved areas and 2% slope for paved areas) Plan shows location of proposed/existing buildings? Plan shows finished floor and pad elevations of new buildings? Plan shows finished grade elevations at building corners? Plan shows cross-sections at critical points along boundary? No abrupt grade changes at the property or boundary line? Overland release path and its elevation shown? Use standard large arrow (small thin arrows are for typical drainage flow in a non-failure situation). Must illustrate where stormwater flows in the event of a total failure of the entire underground drainage system. No excessive or concentrated flow into adjacent properties? If Overland Release is directed into an adjacent parcel, has a proper easement been provided to allow such drainage? Plan shows all surface and subsurface drainage devices? Rim and invert elevations shown? Pipe materials, slopes and sizes shown? All storm drain inlets marked with stormwater pollution prevention message "No Dumping - Flows to Bay"?

Rev. 04-10-20 Page 2 of 4 ---PAGE BREAK--- Engineering Checklist for On-Site Grading / Drainage / Stormwater / Site Improvement Plan Yes N/A ITEM OR DESCRIPTION Completed C.3 Data Form included? The Stormwater Control Plan (SWCP) clearly indicates the following: all Treament Control Measures (TCM's), distinct drainage boundaries for each TCM (drainage boundaries can't share TCM's), details for each type of TCM, installation and long term maintenance notes for each type of TCM and TCM summary Table? Drainage arrows are shown to identify where and how stormwater runoff will enter the Bioretention areas (i.e. bubbler box, curb cuts, etc.)? All downspouts shown to indicate where and how roof drainage will enter Flow-Through Planter (FTP)? Energy dissipators (cobbles or rocks) are shown to avoid erosion at the point where runoff enters the Bioretention or FTP area? Overflow structures are located away and not directly in line with curb openings? Perforated pipe underdrain system shown within Bioretention or FTP area with length, slope and material called out on grading plan or stormwater utility plan? Rims and inverts called out at clean out and overflow riser and are in-line with the Bioretention and FTP details on grading plan or stormwater utility plan? Perforated pipe underdrain system shown within Pervious Paver/Concrete areas with cleanouts shown and length, slope, pipe material called out on grading plan or stormwater utility plan? Rims, inverts and top of subgrade elevations called out at clean outs in-line with the Pervious Paver/Concrete details on grading plan or stormwater utility plan? All curb openings shown on Grading and Drianage plan? Curb openings spaced a minimum 10' apart? Curb openings do not line up with overflow riser structure? All appropriate details included on SWCP or Detail sheet (Bioretention, FTP, curb opening, bubbler, etc.)? A 2-inch minimum drop from flowlne to finish grade of landscape is provided? Height of FTP planter wall or curb adjacent to Bioretention areas does not exceed 4' in total height (top of wall to bottom of footing)? If Yes, see Retaining Wall Section below. Drainage Management Area's (DMA) shown clearly on SWCP? DMA's contain only one Treatment Control Measure (TCM) and TCM is appropriately sized?
