BUA REQUIREMENTS. The maximum amount of BUA allowed for the entire project is 150.654 square feet. The runoff from all BUA within the permitted drainage areas of this project must continue to be directed into the permitted SCMs. The following specific requirements pertain to the BUA on this project: Page 1 of 6 State Stormwater Management Permit No. SW8 010405 a. LOW DENSITY BUA LIMITS. The low-density area, also referred to as Drainage Area 3 in the approved plans and specifications, must not exceed 24% per the requirements of the stormwater rules. Within this low-density area, this permit covers the construction of a total of 3,296 square feet of BUA, which includes 3,296 square feet of proposed BUA. This permit does not provide any allocation of built-upon area for future development within this low-density area. b. SCM BUA LIMITS. The SCMs labeled Detention Pond 1 and Detention Pond 2 have been designed using the runoff treatment method to handle the runoff from 123,807 square feet and 23,551 square feet of BUA, respectively, within the delineated drainage areas. This permit does not provide any allocation of BUA for future development within the delineated drainage area(s). c. #57 STONE. SCM drainage area 1 is proposing 5,429 square feet of#57 stone laid at least four inches thick over a geotextile fabric as a pervious surface for the access road to the back portion of the lot. The underlying soil should not be mechanically compacted prior to installation. If, in the future, this pervious surface is found to no longer meet these requirements, a permit modification will be required. 2. SCM REQUIREMENTS. The following requirements pertain to the SCMs on this project: a. SCM DESIGN. The SCMs are permitted based on the design criteria presented in the sealed, signed and dated supplements and as shown in the approved plans and specifications. These SCMs must be provided and maintained at the design condition. b. PLANTING PLAN. The SCM landscape planting plan shown in the approved plans shall be followed in its entirety during construction. After the plants are established, the operation and maintenance agreement must be followed. c. FOUNTAINS. At this time, a decorative spray fountain has not been proposed within the wet pond. Decorative spray fountains will be allowed in the wet pond if documentation is provided demonstrating that the proposed fountain will not cause resuspension of sediment within the pond or cause erosion of the pond side slopes d. IRRIGATION. If the wet pond is to be used for irrigation, it is recommended that some water be maintained in the permanent pool, the vegetated shelf is planted with appropriate species that can handle fluctuating conditions, and human health issues are addressed. 3. LOW DENSITY AREA REQUIREMENTS. The following requirements pertain to the low- density area of this project: a. LOW DENSITY AND CONVEYANCE DESIGN. The low-density area is permitted based on the design criteria presented in the sealed, signed and dated supplement and as shown in the approved plans and specifications. This low-density area and conveyances must be provided and maintained at the design condition. b. PIPING. Other than the piping shown on the approved plans, only minimal amounts of piping under driveways and roads is allowed within the low-density area when it cannot be avoided. No additional piping is allowed. c. DISPERSED FLOW. The low-density area has maximized dispersed flow of stormwater runoff through vegetated areas and minimized the channelization of flow. Page 2 of 6 State Stormwater Management Permit No. SW8 010405 d. VEGETATED CONVEYANCES. Stormwater runoff that could not be released as dispersed flow may be transported by vegetated conveyances with minimum side slopes of 3:1 (H:V) designed to not erode during the peak flow from the 10-year storm event as defined in the stormwater rules and approved by the Division. 4. NON-ENFORCEABLE SCMS. The existing pond shown on the plans in Drainage Area 3 is not required by the Division and has not been demonstrated to meet the State Stormwater Minimum Design Criteria and therefore is not considered a part of the approved state stormwater treatment system. This additional measure is incorporated only by reference and is not enforceable parts of the permit. 5. STORMWATER OUTLETS. The peak flow from the 10-year storm event shall not cause erosion downslope of the discharge point. 6. VEGETATED SETBACKS.

Important maintenance procedures: _ Immediately after the wet detention basin is established,the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. _ If the basin must be drained for an emergency or to perform maintenance,the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected 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 should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows.
