E. Commence site grading. F. Disturbed areas of the site where construction activity has ceased for more than 14 days shall be temporarily seeded and watered. G. Construction of buildings H. Installation of proposed utilities I. Finalize pavement subgrade preparation. J. Construct all curb, drainage inlets, storm sewer pipes and storm sewer manholes, as shown on the plans. Install temporary inlet protection at the locations of all inlets. K. Dust control. L. Remove inlet protection around inlets and manholes no more than 48 hours prior to placing stabilized base course. M. Install base material as required for pavement. N. Carry out final grading and seeding and planting. O. Clean storm system following construction, clean detention basins of any silt and return to design grades. P. Remove silt fencing/silt sock only after all paving is complete and exposed surfaces are stabilized. Q. Remove temporary construction exits only prior to pavement construction in these areas. Note: Sediment control storage during construction (traps & basins) during construction shall be 134 cy per acre of disturbance per NYSDEC requirements. 112.4 STORMWATER MANAGEMENT Existing site drainage generally flows to two primary drainage areas. The western portion of the site drains toward Slade Avenue, while the remainder of the site is collected by an existing network of catch basins that ultimately discharge through a large storm sewer outlet located near the north central portion of the site. This outlet conveys runoff directly to Cazenovia Creek. Stormwater runoff generated by the proposed redevelopment will be collected and conveyed through a stormwater management system consisting of a wet pond, catch basins, yard drains, manholes, and smooth interior HDPE storm sewer pipe. The proposed stormwater management infrastructure has been designed to accommodate the ultimate full build out of the site and will provide the necessary conveyance, water quality treatment, and peak flow attenuation for future development phases. As a redevelopment project, the site is required to provide Water Quality Volume (WQv) treatment for 25 percent of the disturbed impervious area and 100 percent of any new impervious area in accordance with NYSDEC requirements. The existing site contains approximately 47.75 acres of impervious cover, while the proposed redevelopment will result in approximately 47.0 acres of impervious cover. Since the project does not create any new impervious area, all proposed improvements are classified as disturbed impervious area and are therefore subject to the 25 percent WQv treatment requirement. Because no new impervious cover is being created, no Runoff Reduction Volume (RRv) is required for the project. The proposed wet pond provides 100 percent of the required Water Quality Volume (WQv) treatment for the redevelopment and also provides peak flow attenuation. Discharge from the wet pond is controlled West Seneca Exchange 07/20/2026 Page 12 of 24 Page 833 of 1174
