this general location needs to be relocated or the symbol should be for an existing hydrant. This issue should be clarified. 3. There are two connections shown from the existing trunk sanitary sewer line located on the south side of the site. The most easterly is a deep line intended to collect discharge from the cooler drain. The westerly connection branches off into three stubs into the building. This is due to the architectural layout of the internal workings of the building and may actually be reduced in the final building design. The westerly three connections come into a new manhole, which can be utilized as a sampling manhole. The easterly connection needs to have a sampling manhole prior to connection to the existing trunk line. According to City policy, sanitary sewer services cannot connect to existing manholes. Therefore, the two connections need to be cut into the existing trunk sanitary sewer line by means of a "Y" connection. 4. The driveway connection to Waco Street is relatively close to the driveway connection to the Target site to the south. It would make for better traffic flow if this driveway were moved to the north to align with 18yd Avenue. If the need for the driveway location on Waco Street is for truck traffic servicing the data center, perhaps truck traffic could utilize the Target data center access off of Waco Street and be continued from that location into the UnitedHealth Group site. The connection to Business Center Drive is approximately 150 feet east of the easterly driveway to the clinic located on the north side of Business Center Drive. There is, however, an undeveloped commercial lot east of the clinic site which will likely have additional driveways which can be made to line up with the proposed driveway to the UnitedHealth Group site. It would be impossible to get the UnitedHealth Group's driveway onto Business Center Drive to line up with the existing driveways on the north side, due to the size of the proposed pond. 5. Due to size of the site, a NPDES permit will be required. Along with that permit, a Storm Water Pollution Prevention Plan (SWPPP) needs to be submitted. There is one included in the plan set on Sheet C.5. City policy however is that the SWPPP must be submitted on 8 ~" x 11" paper and signed by the owner, engineer and contractor. Also, proof of the application for the NPDES permit must be submitted. 6. According to City policy, record drawings of the site improvements including sanitary sewer, water and storm sewer facilities must be submitted at the end of construction in both an electronic and paper format. Specific information regarding the format of the submittal can be provided at the appropriate time. If you have any questions regarding any of these comments, please contact me.
