DETAILED INSTRUCTIONS   CONSTRUCTIVE NOTIFICATION   NOTE: The Condition Compliance Monitoring Number (CCM#) will be provided by the Engineering Department during review. The CCM# shall then be used on all annual correspondence the City.   The following information shall be completed:   • Property Address • Property APN • Permit/Project # • Property Legal Description NOTE: The legal description is available in the property owner’s title report. See section IV above regarding Notarize Constructive Notification EXHIBIT A - POST CONSTRUCTION STORMWATER MANAGEMENT SYSTEM OPERATIONS AND MAINTENANCE PLAN PART 1A - GENERAL INFORMATION 1 Property APN(s): If the project has a shared Stormwater Management System (i.e. HOA), insert all the Property APNs served by the SYSTEM. Highlight the Property APN which contains the shared Structural Stormwater Control Measures (SCMs), such as a basin. 2 Project Address(es): where the Structural Stormwater Control Measures (SCMs) to be maintained are located. 3-6 Self-explanatory 7-8 Designer and Company/Firm: Insert name of the original designer of the stormwater management system. In the case that the Designer is no longer available or practicing, the Company/Firm to which the designer worked will be considered responsible to supply information regarding the SYSTEM. 9-11 Self-explanatory 12 Estimated Annual Cost for Maintenance Once Established (Attach Cost Estimate Spreadsheet): Designer to provide an estimate of annual cost to owner for services to inspect, maintain, and report on SYSTEM per instructions provide in this Exhibit. (Consider line item for inflation.) 13 Other Pertinent Info: For example, is the SYSTEM shared? Specifics of how will it be managed. Appendix B‐17    PART 1B - STRUCTURAL CONTROL MEASURE (SCM) DETAILS General: Data provided on these sheets should match information provided in the Stormwater Control Plan (SWCP) or other plans approved by the City of Pismo Beach for the permitted project. A Structural Control Measure (SMC) is defined by the RWQCB as: Any structural facility designed and constructed to mitigate the adverse impacts of storm water and urban runoff pollution. Numbers for SCMs shall be assigned by the City of Pismo Beach officials at approval of the project SWCP or other plan. 1 Purpose(s) of SCM (check all that apply): See City of Pismo Beach Stormwater Management Requirements. 2 Self explanatory 3 Description & Location of SCM (As necessary, refer to PART 2 – Drawings & Photos): The most effective means to describe the location of SCMs on a project site is in reference to a Drawing. (See Part 2 explanation.) If there is a basin serving multiple properties on its own lot, note which properties (by APN) the SCM serves. 4 Drainage Design Criteria: Per approved SWCP or Drainage Plan. 5 Design Details (as applicable): Per approved SWCP or Drainage Plan. If it does not apply, write N/A. 6 Self-explanatory 7 SCM Inspection & Maintenance Requirements: These requirements will be based on the design life and considerations of the SCMs ability to meet requirements for water quality and/or flow control as set out by RWQCB and the City of Pismo Beach. Short Term Requirements include those things that will be required within a reporting year, i.e. clearing of debris, sediment or other obstructions to inlets. Long-Term Requirements would be those things done on multiple-year schedule (2-year, 5 year, 10 year) to ensure the continual proper functioning of the SCM. For example, for a filter strip or biofiltration swale, include a plan ensuring the vegetation is healthy and method for replacement of plants (planting plan). For basins (infiltration or detention), provide a schedule for vegetation management and sediment removal. The replacement of inlet grates or other devices that could rust or degrade should be considered in this area, along with the design life. PART 2 - DRAWINGS AND PHOTOS The official documents related to the approved design of the Project’s Stormwater Control Measure(s) (signed by the Engineer of Record) are required as a part of the Plan. If changes are made to the design of the SCM during construction, Record Drawings must be submitted. Include dated photos of the completed SCM with pertinent notes (i.e. direction from which the photo was taken.) Reduced size Site and Drainage Plans and/or Details Sheets shall be provided. Any relevant details shall be copied at the original scale on 8.5x11 (for example, on an exhibit) for inclusion in the Plan. Ensure any exhibits include all the listed components. Appendix B‐18    PART 3 - CERTIFICATION AND APPROVAL Along with the Owner and Designer, the designer or a 3rd party professional engineer, geologist, architect or landscape architect is required to field verify the Stormwater Control Measure(s) per RWQCB Resolution No. R3-2013-0032 Attachment 1, Section D. Field Verification of Post-Construction Stormwater Control Measures. Prior to the submittal of this Plan, it is recommended that the field verifier signatory and City official signatory visit the site together to inspect the SCMs, discuss the proposed plan and any potential issues prior to submittal. EXHIBIT B - POST CONSTRUCTION STORMWATER MANAGEMENT SYSTEM OPERATIONS AND MAINTENANCE CHECKLIST TEMPLATE General: The initial purpose of Exhibit B is to produce a template checklist which will be used for inspections and submitted to the City annually by June 15th. The approved template will be included in the recorded document, so consideration of checklist items that meet the short and long term maintenance requirements of the SCM is important. Since each SYSTEM design is different, it is the responsibility of the designer/engineer to advise the owner in completing the checklist, which must be approved by the City prior to recordation. For this reason, the template can change in content to meet the particular SCM’s maintenance needs. Two examples are included for a Biofiltration Area/Swale and Catch Basin(s). Suggestions for Inspection Timing: Note that the official rainy season in California is October 15th – April 15th, so annual inspections of SYSTEMS would logically occur before October 15th to beat the possibility of a storm coming before any required maintenance is undertaken. Monthly inspections could be scheduled along with planned landscaping maintenance of the overall site, so the removal of vegetation debris or sediment could be done simultaneously. If the Project is a HOA-run development or similar, it will be beneficial to consider the project Operations & Maintenance schedule and add the SYSTEM maintenance therein. Inspectors: It is required for a licensed Civil Engineer or Qualified SWPPP Practitioner (QSP) to sign off on the checklist annually. However, this does not prevent the signatory from delegating inspection responsibly to trained maintenance staff. All inspectors must be listed, and initialed to designate who did each inspection. However, the responsibility for certifying that the information provided is true & correct rests on the signatory. Corrective Action/ Required Maintenance: Inspectors shall estimate how long it will take to rectify the situation in discussion with the owner, and re-inspect promptly. Any issues that are not addressed shall be recorded.
