The remainder oi the south central wetland and the ��?y southeastern most wetland that abuts Casino Road would be 'j� "' � retained and incorporated into the mitigation plan. 5. Mitigation Design. The proposed mitigation area will be located in the southeast corner of the Fite (SD-1) , and would incorporate the ~ southeastern portion of the middle wetland and all of the southeastern wetland. The entire site, minus the buffer area, will constitute a 1.3: 1. replacement in acres of wetlands over those areas to be lost with the proposed development. � The mitigation area will consist of an excavatecl '�1 retention/detention area which duplicates the conditions and �_' the functions uf the wetlands that occur under existing conditions . The area will be revegetated using a mix of .. native plant species and nursery stock plus seedings and plant ' ; slips (i.e. , individual non-rooted shoots of wetland dependent shrubG and trees) . (See attached planting plan) � � Grass lined swales wi. 11 be constructed around the �� „ periphery o[ the south and east side ot the site (SD-3 and SD- '_1 5) . Thc swales will be 1.1..5 feet wide at the top with 3: 1 slope down to a 3.5 foot wide bottom. They will graded at a 3- ' S percent slope to create slow flows which will expedite � biofiltration. The swales will be planted with a dense low � ' « grass/soft rush mix to provide a dense vegetative ground cover ' both in the summer growing season andl nts haveh beennselected grasses become dormant. Low growing p ��' to maximize the sunlight or openness and to avoid dense tall ' monocultures which frequently occur with cattail or big sCem `� bulrush. 2
