Infiltration Basin & Trench, cont. B. CALCULATIONS 1. The basin or trench must draw down within 5 days. Spray irrigation is not acceptable as the sole means of drawdown. 2. The design storm is 1.5" if the project is subject to Phase 11 or is sited within '/z mile of and draining to SA waters. The design storm for projects subject to Phase II sited within '% mile of and draining to SR waters must treat the difference between the pre and post development conditions for the 1-yr 24-hr storm. Otherwise, use 1" design storm. 3. Report the bottom surface area. 4. Report the surface area at the overflow elevation. 5. Show the calculation for the minimum required volume. 6. Provide a table of elevations, areas, incremental volumes and accumulated volumes to demonstrate that the minimum required volume has been provided. 7. Calculations are signed, sealed & dated. 8. Report the Drainage Area and Built -upon area for each basin or trench. 9. The seasonal high water table must be at least 24" below the proposed bottom elevation of the system. For Phase II projects, at least 12" of this must be in naturally occurring soils. 10. All runoff in excess of the design storm must bypass to a vegetated filter prior to entering the basin or trench. If the system is designed to store a larger design storm (generally 2-3 times the minimum), the requirement for an offline bypass can be waived. Please contact the Division to determine what design storm is appropriate for the project. �12.L , / `% Infiltration Basin & Trench, cont. C. PLANS - Plan sheets should be kept to a minimum.

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 be taken 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).
