APN: 028-304-74 Reviewer: Jennifer Buckley 1st Routing Comments - Approved

Based upon Stormwater Management's review of the submitted civil plans (dated March 2023) and Drainage Report (dated 19 March 2021 with latest revision date of 17 August 2021) by RI Engineering, Inc., the application to remodel and construct an addition to a residence (totaling 1,491 square feet of new and/or replaced impervious area) has been approved. The plans show runoff will be directed to a percolation pit and/or biotreatment swales. If subsequent revisions are made to drainage patterns or impervious areas, Stormwater Management requests to review the revised plans.

Please note, the following two holds will be placed on the permit. These items are not required to be addressed/completed prior to resubmittal.

1. Please notarize and record a maintenance agreement (SWM-25A form) that includes the approved drainage plan and maintenance schedule as a packet. It will be the responsibility of the property owner to inspect and maintain all drainage features. Please contact the County of Santa Cruz Recorder’s office for appropriate recording procedures. The maintenance agreement form can be picked up from the Public Works office or can be found online by navigating to County of Santa Cruz Public Works Department, Stormwater, Permit Requirements, SWM-25A.

2. Upon approval of the project, a drainage “Hold” may be placed on the permit and will be cleared once the construction is complete and the stormwater management improvements are constructed per the approved plans: In order to clear the Hold, one of these options shall be exercised:

a. The Civil Engineer / Designer must inspect the drainage improvements on the parcel and provide public works with a letter and photographs confirming that the work was completed per the plans. The Civil Engineer / Designer’s letter shall be specific as to what was inspected (such as invert elevations, pipe sizing, the size of the mitigation features and all relevant design features). Notes of “general conformance to plans” are not sufficient.

b. As-built plans stamped by the Civil Engineer may be submitted in lieu of the letter. The as-built stamp shall be placed on each sheet of the plans where stormwater management improvements are shown.

c. The Civil Engineer / Designer may review as-built plans completed by the contractor and provide the County with an approval letter of those plans, in lieu of the above two options. The contractor installing the drainage improvements will provide the Civil Engineer / Designer as-built drawings of the drainage system, including construction materials, invert elevations, pipe sizing and any modifications to the horizontal or vertical alignment of the system. The as-built drawings, for each sheet showing drainage improvements and/or their construction details, must be identified with a stamp (or label affixed to the plan) stating the contractor’s name, address, license and phone number. The Civil Engineer / Designer will review the as-built plans for conformance with the design drawings. Upon satisfaction of the Civil Engineer / Designer that the as-built plans meet the design intent and are adequate in detail, the Civil Engineer / Designer shall submit the as-built plans and a review letter, stamped by the Civil Engineer / Designer to the County Public Works Department for review to process the clearance of the drainage Hold, if the submittal is satisfactory.
