Storm Sewer: Figure 6.3F in the EDA Study shows the existing storm drainage system in and around the site. The current system incudes both closed and open drainage ways. Pipe sizes range from 10" to 66" in diameter. The ditch through the center of the Burkland site carries water from along :t\1ain Street to the Q-Street ditch, which flows west to east past the northern border of the site. Surface runoff from the residential area to the east is directed into ditches that flow west onto swales on the Burkland site. The EDA study states that .the Burkland site could be served for industrial development by replacing the open ditch with Ita 66" pipe through the Iniddle of the Burkland site and utilization of the existing systenl \vithin the 1\1cKenzie Highway. II As the applicant's engineers have determined, the saIne solution \\'ould fully serve the proposed mixture of residential and commercial uses enlbodied in the applicant's proposal for the site. As they say, "The proposed development would cause less inlpact on the storm sewer system than was originally anticipated for heavy and light industrial development. Residential developments have a smaller percentage of imperllleable surface areas than industrial sites that typically have requirenlents for large structures and paved surfacing. II Modifications to the existing drainage systelTI shall be approved upon site review and shall be such as will, on balance, protect and enhance its amenity and resource values, maintain or slow runoff rates, and preserve or enhance its carrying capacity, consistent with applicable plan policies and wetlands regulations. Goal 12 - Transport.ation. This goal requires the provision of a safe, convenient, and economic transportation system to move people and goods between geographic and jurisdictional areas. The site plan proposes a north-south through street that runs from Main Street on the south along the west side of the centerline drainage ditch and will exit from the north-east corner of the property, just south of the wetland/woodland preserve, onto an access leading to 32nd Street. This will provide two points of access to Main Street both for residents of the new developments and for residents of the existing residential area to the east, who have expressed a desire for improved circulation and access. The roadway will also provide bus access to all parts of the development. A bus stop and shelter facility \\'i11 be designed in cooperation with the Lane Transit District to allow residents access to mass transit ,without having to cross Main Street. Current traffic volumes on Main Street nea~ the site are at acceptable levels, varying between Level of Service B and Level of Service C. These levels of service reflect urban traffic volumes but also reflect smooth and unobstructed flows of traffic at urban speeds. The City of Springfield's Transportation Department has advised the project engineers that the Department does not foresee problems with the traffic volumes associated with the proposed project. If an impact study reveals a need for a traffic signal, refuge lane, or other improvements, such improvements shall be provided for at the ti Ine of site review. 10
