XV. Infrastructure E�ansions The majority of required infiasttucture for the Twin Lakes Business Park is currently in place with the exception of the Twin Lakes Pat�kway and interior sanitary sewer, water main and sb�xn sewer extensions west of Fairview Avenue. Major ir�f�uctrm� improvements are not necessary to redevelop parcels located east of �'aixuiew Avenue, however minor utility relocations and curb cuts in Terrace Drive may be required in some ar�eas. The full redevelopment of interior parcels located west of Fairview Avenue will require the construction of Twin Lakes Parkway. Twin Lakes Parkway is proposed to begin at the intersection of Cleveland Avenue and the nortllbound I-3 5 W entrance/exit ram� and run east to the intersection of Fairview Avenue and Terrace Drive. The parkway is proposed to be approximately 3100 feet m length and include two 16-foot wide through lanes with �� t�nn lanes and a center median throughout. A separate bituminous pedestrian trail is also proposed along the parkway. Sanitary sewer facilities are proposed to be constructed along Mount Ridge Road to serve interior parcels m the development. Approximately �� feet of &inch sanitary sewer is proposed to be constructed The City's Sanit.ary Sewer Plan estimates total flows for the entire City of 1,910 Mgal/yr m 2000, 2,079 MgaUyr in 2010, and 2,144 M�al/year by 2020. The development of Twin Lakes as outlined in the AUAR is asstuned within these total City numbers. The entire Twin Lakes area has a current estimated sewer flow of 74 MgaVyr. At fitll development Twin Lakes will have an estimated total sewer flow of between 180-217 MgaUyr, or an increase of 106-143 Mga1/yr over the existing development pattern. The City does not anticipate that full development will occur by 2010 and therefore the worst case scenario increase is not expected to occur unti12020 or beyond depending upon market forces and public financing sources for brownfield redevelopment. Water main facilities may be constructed along Mount Ridge Road easement and Twin Lakes Parkway to serve interior parcels m the development and provide additional loops withitl the City water main grid Appro�mately 3000 feet of 8-inch diameter water main is proposed to be constructed along a portion of Twin Lakes Parkway. Appro�mately 2000 feet of 12-inch diameter water main i s proposed to be constructed along the existing Iona Lane utility easement and the Twin Lakes Parkway. Storm sewer facilities include catch basins for the two proposed roadways witll tnmk sewer running to existing storm water treatment ponds. Additional tr�mk sewer facilities will be constructed to provide connections between proposed parcels and existing storm water treatment ponds. Appro�mately 3500 feet of 12-inch through 36-inch diameter storm sewer is proposed to be constructed 'm conjunction witll ultimate development m the Twin Lakes Business Park. ��
