• KUKHOTSKIY DUPLEX Element# 10: Control De-Watering • De-watering of the site is not expected. If dewatering of the site is needed, all groundwater removed shall be retained and recharged into the ground after de-watering has been finalized. Element# 11: Maintain BMPs All Temporary Erosion and Sedimentation Control (TESC) devices and equipment will be • inspected and maintained on a weekly basis_ if not sooner, based on storm events contributing to runoff. When construction is complete and the site is stabilized, any existing sediment will be removed and stabilized onsite. Element# 12: Manage the Project A general construction manager will manage the project for or by the owners. The construction manager shall maintain all the above items in order to minimize sediment transport and turbid water leaving the site. His job will entail continual observation of the grading operations to ensure minimal effects to adjacent properties and offsite waterways. Element# 13: Protect On-Site Stormwater BMPs • Compost amended vegetated areas and future infiltration areas will be protected from compaction and sedimentation when feasible during construction. Minimal Requirement # 3: Water Pollution Source Control All proposed development is to consist of residential construction.No water pollution • source control is needed. Minimum Requirement # 4: Preservation of Natural Drainage Systems and Outfalls, and provisions of off-site mitigation • No changes to the existing drainage systems and outfalls are proposed with this development. All proposed runoff from the project area is to disperse to maintain natural drainage paths and systems. Minimum Requirement #5 On-Site Storm Water Management • Due to the project proposing more than 5,000 sf of new hard surfaces, Minimum Requirements 1 through 9 must be evaluated. As such, the project shall use List#2 to evaluate on-site stormwater management BMP feasibility. • • • WESTERN ENGINEERS,INC. 15 PROJECT: 19-1825-A
