Describe what measures you will use (before and after construction) to minimize impacts to the waterway or wetland. <br /> Construction erosion control practices will include protection of existing storm water conveyance structures and <br /> stockpiles. Silt fence and silt screen (turbidity barrier) will be used to protect the features. Temporary seeding and <br /> mulching of topsoil stockpiles will be required if material is not scheduled to be moved within seven days. Dust control <br /> and tracking prevention along with the compliance to the Lane Regional Air Pollution Authority Air Permit No. <br /> 202543-125 will be spelled out in the plans and specifications. Erosion mat will be installed in drainage swales and <br /> ditches when applicable. <br /> <br /> ' Permanent erosion control will consist of seed, fertilizer and mulch on all topsoil areas and riprap at culvert and storm <br /> Structure openings. Temporary erosion control devices will be removed upon establishment of <br /> permanent vegetation. <br /> Construction access and staging will not impact wetlands. Construction access will be via Highway 99 to Airport <br /> 'Road. <br /> Impact area is o Ocean o Estuary o River o Lake o Stream X Freshwater Wetland <br /> Note: Estuarine Resource Replacement is required by state law for projects involving intertidal or tidal marsh <br /> alterations. A separate Wetlands Resource Compensation Plan may be appended to the application. <br /> ,Has a wetland delineation been completed for this site? X Yes. <br /> ~IIf yes, by whom: The current project (the Airport Road Realignment) was delineated in 2004 and 2005 by <br /> ,Coyote Creek Environmental Services, loc., and the Report of Findings is submitted with this JPA. <br /> !,Has the wetland delineation been approved by DSL or the COE? O Yes X No Review will be concurrent <br /> ~Iwith this application. <br /> 'Describe the existing physical aad biological character of the wetland/waterway site by area and type of resource. <br /> '(LTse separate sheets and photos, if necessary.) <br /> 'For wetlands, include vegetation, Cowardin and Hydrogeomorphic Method (HGM) class, position in the landscape, prior <br /> !,disturbance, soil types, hydro period, summary of functional assessment. <br /> The Study Area (a corridor approximately 125 feet in width centered on the proposed alignment) is bordered on the <br /> ',north by Airport property (generally used <br /> for Airport purposes or in cultivation for grass seed), on the east by a <br /> '.mixture of light industrial and residential, on the west by Airport properties, and on the south by cultivated <br /> ',agricultural lands. A few scattered residences are present immediately north and east of the southern realignment <br /> 'segment. <br /> ~~!The Study property has been and is actively cultivated. The Eugene Airport leases all of their open lands beyond the <br /> Runway Safety Area for cultivation, partly to keep the lands economically productive, and partly to discourage wildlife <br /> 'habitat from becoming established. <br /> 'On-site sampling confirmed the general presence and layout of hydric soils, as mapped by the Soil Survey of the Lane <br /> 'County Area. Hydric soils are found in broad bands organized along the several drainages that flow from the south to <br /> ,ditches along Airport Road. <br /> 'Vegetation in the cultivated <br /> fields is not representative of wet or dry conditions, but simply representative of the e,,~`orts <br /> of the local farmer. Along the drainages in uncultivated areas, more representative vegetation is allowed to persist. <br /> .The roadside ditch along the south side ofAirport Road supports wet-tolerant vegetation only in the lower portion of <br /> .the ditch. Se uential surve s were conducted or rare lasts ties and no rotected !ants were ound to be resent. <br /> Coyote Creek Environmental Services o„~ice: (541) 484-7336 <br /> <br />
