Transitions from graded areas to existing unmodi~ed creek channels shall be carefully designed to avoid creation of nickpoints~ and abrupt changes in channel conditions that could lead to instability. Steepened channel reaches shall. where necessary, include channel grade controls. Energy dissipation structures shall be included in the design of the outlets of culverted sections of the creek to avoid erosion of creek channels. Golf cart creek crossings shall be designed to eliminate potential erosion impacts associated with golf carts in creeks. Either bridges or paved surfaces shall be provided at each crossing. Obstructions (e.g., appropriate vegetation and rocks) shall be placed along the creek at each crossing to discourage "off-path" travel through the creek channels. Timing: Prior to approval of a ~nal design for the Golf Course. G10. An Integrated Pest Management Plan (IPM) shall be prepared by a qualified agronomist or tuff grass specialist. The IPM shall by guided by the principles of ( 1 ) minimizing the use of pesticicles on the Golf Course, (2) using pesticides only in response to a persistent pest problem, (3) prohibit- ing preventative chemical use. and (4) fully integrating cultural and biological approaches to pest control into the IPM, ~vith an emphasis toward reducing pesticide application. Consistent with these pnnciples. the IPM will: · Address and recommend methods of pest prevention and tuff grass management that use pes- tieides as a last resort in pest control. ~ · Specify types and rates of fertilizer and pesticide application. Special attention in the IPM shall be directed toward avoiding runoff of pesticides and nitrates into sensitive drainages or leach- ing into the shallow groundwater table. · Detail how fertilization requirements are to be reduced dunng tuff grass grow-in. Fertilizer requirements for turf grass germination and maturation can be lowered by ensuring topsoil is maintained or replaced dunng grading operations to sustain the organic quality of the native soil. Organic amendments such as sludge, manure, fir bark, or peat greatly increase the organic quality of the soil and greatly reduce fertilizer needs. These organic amendments also increase percolation rates and act as stronger binder for the adsorption of fertilizer and pesticide com- pounds. Soil tests shall be performed prior to seeding to determine the proper fertilization rates pre- and post- seeding. Timing: Prior to approval of a ~nal landscapeplan for the Golf Course. G11. A Water Quality Monitonng Plan shall be prepared and implemented to evaluate the effectiveness of the Storm Water Pollution Prevention Plan (SWPPP; see the discussion of NPDES requirements on p. 89 of the DEIR) and Golf Course Design and Management Plan (See Requirement Gg, above) at protecting surface and groundwater quality in the vicinity of the site. The Water Quality Monitoring Plan shall include the following: · Identification of sampling locations. The plan shall establish fixed surface and groundwater sampling locations. Surface water samples shall be collected from detention basin outlets dur- 1 The point of abrupt steepening of a stream profile. 12
