BACKGROUND INFORMATION: The State Water Resources Control Board issued the City of Lodi PermitWDID No. 5B39NP00028 that governs the discharge of storm water runoff. A condition of that permit requires the adoption of developmentand redevelopment design standards per Attachment No. 4 of the State's General Discharge Permit. These standards were scheduled to be in place by May of 2007. The Public Works and Community Development Departments have been working with WGR Southwest, a local firm with expertise in this area, to prepare development standard plans (DSP) that would comply with the requirements of the State's Attachment No. 4. The DSP address all new development and qualifying "significant redevelopment". New development project categories that trigger DSP are defined as commercial developments of over 100,000 square feet, automotive repair shops, retail gasoline outlets, restaurants, parking lots of over 5,000 square feet or 25 spaces, and housing subdivisions of more than ten units. Significant redevelopment is defined as creation or addition of at least 5,000 square feet of impervious surfaces on an already developed site. The typical DSP consists of an activity -specific Best Management Practices (BMP's) that alone or in combination with other BMP's achieve the water quality objectives of the regulations. Staff has held several meetings with members of the building industry and has met with the Executive Officer of the Building Industry Association (BIA)to discuss these changes. These standards require an annual inspection of the post construction Best Management Practices (BMP's) to confirm they are being maintained and operated correctly. The proposed $122 inspection fee is the same fee charged for construction inspections related to erosion control during construction. The property owner would be billed for each inspection when completed. Should a site require multiple inspections, that expense would also be billed. The inspection fee would be subject to inflationary price adjustments. Subdivision developments would be required to establish an assessment district to address the inspection of post construction BMP's. These properties would be tracked by GIS plotting and recorded with the County Assessor's Office.

California State Water Resources Control Mrd adopted a NPDES Permit for the discharge storm water from storm drainage systems of n ici pal ities with a population < 100,000. Ii was identified by the State as one of these nicipalities and, therefore, prepared a Storm :er Management Plan (SWMP) in January B. s DSP was prepared in accordance with the uirements contained in the City's storm :er permit (Attachment 4) and the SWMP. J J J Phase I cities (Stockton, the Port of Stockton, ramento) and many Phase II cities (San quin County, Tracy, Lathrop, Manteca) have !ady implemented their version of the DSP. relopers who have projects in these other es or in the County have already had to nply with these regulations for, in some es, several years. Lodi's DSP Calendar of Events 006- State required the DSP to be in place and enforced by May 2007. 6- Staff advised the building community that Attachment 4 requirements are required. 7- Draft DSP prepared and reviewed with Community Development and Public Works. 007- During the Hutchins Street Square Got SWPPP Event, the DSP was presented to the building community. There were 65 attendees — 5 different development companies were present. 07- A workshop held by the San Joaquin Storm Water Partnership at Micke Grove presented the DSP requirements to the 49 attendees.
