G5. The developer of the Spotomo Flat area is required to replace crossroad drain lines with properly- sized culverts, improve site drainage by constructing an earthen vee ditch with consistent fall (or other comparable improvement), and construct storm water detention facilities on the Spotomo Flat Area. Timing: Prior to acceptance of public itnprovements in the Spotorno Flat area. G6. In the Spotorno Upper Valley Medium Density Residential area, construction of storm water detention facilities to reduce increases in runoff into Sycamore Creek is required. Timing: Prior to occupancy of new homes in the Spotorno Upper Valley Medium Density Resi- dential area. G7. Evaluation of the existing Spotomo Dam by a qualified professional engineer is required. This evaluation would address safety and stability. If any needed upgrades are identified as a result of this evaluation, they would be completed prior to completion of the Bypass Road. Timing: Evaluation prior to ~nalization of construction specifications for the Bypass Road; upgrades. if necessary, prior to completion of the Bypass Road. GS. The Golf Course improvements include construction of a maintenance facility for servicing of equipment required for Golf Course operations (suc~n as mowers and aerators) and golf carts. The maintenance of this equipment would be conducted within a building or under a roofed and paved area to isolate spills or residues of maintenance-related pollutants from storm water rimoff. The maintenance area would also be the site of hazardous materials (e.g., lubricants, coolant, and cleaners) storage and an aboveFound fuel tank. The maintenance area would be operated under a Storm Water Pollution Prevention Plan that would include implementation of structural e.g., drain- age inlets with oil/water separators or filters, secondary containment for hazardous spills) and non- structural (e.g., "good housekeeping" policies, dry cleanup of spills) Best Management Practices (BMPs). Timing.' Prior to approval of a final design for the Golf Course. G9. A Golf Course Design and Management Plan shall be developed that. when properly implemented, would reduce or eliminate impacts to surface water quality from Golf Course operation and main- tenance. This plan would, at a minimum: · Minimize Golf Course runoffinto nearby creeks. The plan would require (1) a minimum ten- foot natural vegetated buffer between the edge of irrigated turf grass and the top of bank of sen- sitive drainages and (2) drainage of all maintained tuff areas away from nearby creeks and toward facilities planned to accommodate and manage runoff. These runoff management facilities include the new lake(s) planned for the Golf Course and grassed swales, area drains, and/or sumps for percolation. Flow of Golf Course drainage away fi'om creeks and drainage channels must be shown on grad- ing and drainage plans. Areas of maintained turf grass that drain towards creeks and drainage channels shall be mini- mized, and any such areas shall be indicated in the grading and dr~iinage plans. Those areas 10
