L In the space provided below, y brief -I summarize how the stormwater runoff will be treated, summz
Stormwater runoff from the developed areas of the site will be captured and treated in three in -filtration
basins and two wet 12ands
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:

b. If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
[] Coastal SW - 1995 El Ph 11 - Post Construction
3. Stormwater runoff from this project drains to the CLipc. Fear I'Ziver basin.
4. Total Property Area: 109.723 —acres 5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 2,494 acres
