• • • FEB -05 -2003 12 :46 Engineering Review Bruggeman Properties, LLC CITY OF LINO LAKES 651 982 2499 P.09/11 Page 2 February 4, 2003 however, it is unclear as to which buildings that this system would serve or where it would connect to. Thus, further information will be necessary to determine if the sanitary sewer system will meet City requirements. It is strongly urged that a gravity sanitary sewer system be investigated for the entire parcel for present and future proposed development. The ten (10) inch PVC sanitary sewer piping shown on the plan sheet will not be allowed if it will be installed as a slope reducing mechanism only. The residential properties on the west side of Hodgson Road do not currently have sanitary sewer service from the City. However, it is the right time to evaluate whether the proposed sanitary sewer system to the Bruggeman Properties can also serve these properties. Public cost would be increased if this option is possible. Sanitary sewer system materials and installation shall follow City of Lino Lakes engineering standards. MPCA will require a permit for the sanitary sewer system installation, and the City will need permit verification prior to field construction. 2. Watennain System The watermain system layout as shown on plans (Sheet U1) in general is acceptable depending on connection for looping on either the north side (Birch) and/or the east side (Ware) of the overall project site. That is, the overall project site will need to be considered for watermain layout and sizing prior to approval of the commercial /retail portion of the development site. Also, if wet taps to the existing 12" watermain on Hodgson Road are necessary due to gate valve position, then a tapping sleeve with gate valve will most likely be necessary. A permit will be necessary from the Minnesota Department of Health (MDH). The City will need permit verification prior to field construction. Watermain system materials and installation shall follow City of Lino Lakes engineering standards. 3. Stormwater System From the submitted plans (G1) and the stormwater calculations (existing and post development), the information submitted was incomplete to determine stormwater compliance with City of Lino Lakes requirements. For example, a drainage area map with divides was not submitted so that the runoff / stormwater calculations could be tracked. Stormwater conveyance systems (piping and catch basin) were not included in the HydroCAD modeling. Thus, more detailed stormwater runoff and routing information will be needed.
