WATER MAIN SYSTEM <br /> <br />Each of the proposed home sites have been designed to be serviced with city <br />water. The proposed water main system will help to create a looped water <br />system, connecting the 50th Street System to the St. Croix Sanctuary’s system, <br />which will help to improve water quality in the water main line and better flow <br />for fire flow protection to this and area developments. City hydrants will be a <br />part of the water main system and will be spaced according to city and state <br />requirements. <br />EXISTING GAS PIPELINE <br /> <br />There is a high-pressure gas main that bisects the parcel and will require <br />permitting for crossing the main for road and for any utilities. We are <br />experienced with this type of crossing and see no issues that would result from <br />the proposed design. <br /> <br />STORM SEWER AND PONDING <br /> <br />The natural rolling nature of this site facilitates a design of storm ponding and <br />infiltration systems. The storm design will allow for a treatment train of <br />ponding, swales and infiltration areas to clean and reduce the impacts to the <br />existing natural wetland features of the site. The storm sewer ponding facilities <br />will be designed to meet both the State and Watershed Requirements for <br />infiltration and for rate of runoff. <br />The site has land locked basin(s) that the Watershed District recently conducted <br />a study which subsequently lowered the flood elevation for the wetlands <br />located on this site. This will require the revision of the flood boundary and a <br />letter of map revision sent to FEMA for a few of the proposed lots as identified <br />on the plan. <br />HOME SETBACKS AND BUFFERING <br /> <br />All proposed home construction will be limited to the setback as identified in <br />the city code. Currently the plan as designed meets the setbacks and no <br />variance is requested. <br /> <br /> <br />
