DESIGN STANDARDS This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. 2. This stormwater system has been approved for the management of stormwater runoff as described in Section 1.7 of this permit. The stormwater controls labeled 1 and 2, have been designed to handle the runoff from 16,771 and 15,250 square feet of impervious area, respectively. A 50' wide vegetative buffer must be provided and maintained adjacent surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and rivers and the mean high water line of tidal waters. 4. The tract will be limited to the amount of built -upon area as indicated in Section 1.7 of this permit, and per the application documents and the approved plans. This permit does not provide any allocation of built -upon area for future development. All stormwater collection and treatment systems must be located in public rights - of -way, dedicated common areas or recorded easements. The final plats for the project will be recorded showing all such required rights -of -way, common areas and easements, in accordance with the approved plans. The runoff from all built -upon area within the permitted drainage area of this project must be directed into the permitted stormwater control system. Page 2 of 7 Permit Number: (m be provided by DA1Q) Drainage Area Number: Bioretention Operation and Maintenance Agreement I will keep a maintenance record on this BMP. This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important operation and maintenance procedures: — Immediately after the bioretention cell is established, the plants will be watered twice weekly if needed until the plants become established (commonly six weeks). — Snow, mulch or any other material will NEVER be piled on the surface of the bioretention cell. — Heavy equipment will NEVER be driven over the bioretention cell. — Special care will betaken to prevent sediment from entering the bioretention cell. — Once a year, a soil test of the soil media will be conducted. After the bioretention cell is established, I will inspect it once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows.
