'The redevelopment drainage area was originally permitted in 1995 and was expanded in 2022 to cover more project area. The area added in 2022 is subject to the 2017 rules.
Sheet 5 shows the area permitted in 1996. Sheet 1 shows the entire campus area including SW8 190107, which remains permitted separately. The area subject to the 2017 rules
is outside of the 1996-permitted area and also outside of SW8 190107.
2The property is 38.88ac, and contains 0.52ac coastal wetlands. The resultant project area is 38.36ac.
3These three permits were combined on June 3, 2022. SW8 970426 and SW8 020908 were rescinded.
°The original SW8 960424 permit set 7/16/1996 as the baseline date for redevelopment as shown on Sheet 5 of 25. On that date 188,923sf of impervious was inside SW8 960424.
After accounting for the impervious that has since been demolished, impervious that remains, impervious that was built unpermitted, permitted redevelopment from 1996
(57,654sf), permitted redevelopment from 2020 (2,400sf), and a permitted trail added in 2022 (21,205sf), the amount that remains available for redevelopment outside of a
permitted drainage area is 53,500sf.

I Rainwater Harvesting Maintenance Requirements I
Important operation and maintenance procedures:
The roof area will be maintained to reduce the debris and sediment load to the system. Excess debris can clog
the system and lead to bypass of the design storm, and reduced reuse volume.
To ensure proper operation as designed, a licensed Professional Engineer, Landscape Architect, or other
qualified professional will inspect the system annually.
The system components will be repaired or replaced whenever they fail to function properly.
If the outlet is metered, use must be recorded at a minimum of monthly. These records shall be kept on site for
inspection by DWQ.
The system will be inspected by the owner/operator at least monthly and within 24 hours after each rain event. 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. Any problems that are found shall be repaired immediately.
