The New England Erosion Control/RestorationMix contains a selection of native grasses and wild flowers designed to colonize generally moist, recently disturbed sites where quick growth of vegetation is desired to stabilize the soilsurface. This mix is particularly appropriate for water quality/detention basins which do not normally hold standing water. The plants in this mix can tolerate infrequent inundation butnot constant flooding. The New England Erosion Control/Restoration Mix contains the following species: Switchgrass, Virginia Wild Rye, Creeping Red Fescue, Fox Sedge, CreepingBent Grass, Silky Wild Rye, Nodding Bur-marigold, Soft Rush, Grass-Leaved Goldenrod, Sensitive Fern, Jo-Pye Weed, Boneset, Flat-Top Aster, New York Aster and Blue Vervain.The seed mix shall be applied at a rate of 1 pound per 1,245 square feet of disturbed area.Disturbed areas on the water quality/detention basin berm and exterior thereto which are not anticipated to contain the hydrology required to support the New England ErosionControl/Restoration Mix shall be prepared by spreading ground limestone equivalent to 50% calcium plus magnesium oxide applied at a rate of 50 pounds per 1,000 square feet.Fertilizer (10-10-10) is to be applied at a rate of 7.5 pounds per 1,000 square feet. Following the initial application of lime and fertilizer, there are to be no periodic applications of limeand fertilizer. Disturbed areas will be seeded with a seeding mixture of Kentucky Bluegrass applied at a rate of 20 pounds per acre, Creeping Red Fescue applied at a rate of 20 poundsper acre and Perennial Ryegrass applied at a rate of 5 pounds per acre for a total application of 45 pounds per acre. A hydroseed mix containing comparable cultivars shall be anacceptable substitute. In the event that a hydroseed mix is not utilized, after seeding, the areas seeded shall be stabilized with hay mulch immediately applied at a rate of 70 pounds per1,000 square feet, and anchored by tracking. Seeding shall only occur between April 15 and June 15 and August 15 to October 1.17.As future areas of the project site are cleared and grubbed, the Applicant shall install, in the downgradient locations as delineated on the Erosion Control Plan, temporary sediment trapsin a size sufficient to accommodate 134 cubic yards of sediment for each acre of disturbed area draining to the temporary sediment trap.18.Upon completion of the installation and stabilization of the water quality/stormwater detention basin, construction shall progress sequentially in the first phase of project development inaccordance with the site development plan.19.All utility installations, including stormwater, the potable water distribution system and sanitary sewer facilities shall be installed in accordance with the design plans utilizing thetrenching, compaction and cover requirements as hereinbefore set forth.20.As the stormwater drainage system is being sequentially completed, the Applicant shall install sediment control devices in each installed catch basin.21.Areas for road and parking construction and building construction in the first phase of the project shall be ³ER[HGRXW´ and/or excavated, as the case may be, in accordance with thespecifications, and at the elevations, depicted on the project site development plan.22.Excavated material derived from site development shall either be utilized as structural fill in fill areas in the first phase of the project or stored in soil stockpiles.
