Ms. Katie Larsen <br />7/6/2022 <br />Page 2 <br />Villas on Vicky Concept Plan Engineering Memo <br />functional rear yard drainage system. <br />Ponding areas shall not be within the public right-of -way. <br />•Water Supply <br />The existing property is identified as a Stage 1A Planned Service Area in the 2040 <br />Comprehensive Plan. There is an existing 8-inch diameter ductile iron pipe (DIP) water main <br />along the south side of Vicky Lane and an existing 12-inch diameter DIP water main along the <br />east side of Lake Drive (CSAH 23). <br />It is feasible to extend the water main to service the proposed lots. However, the size of the water <br />main will have to be determined and the water main will most likely need to be looped through <br />the site. All proposed units will be required to connect to the City’s water system. <br />•Sanitary Sewer <br />The existing property is identified as a Stage 1A Planned Service Area in the 2040 Comprehensive <br />Plan and is in the 2B sanitary sub-district. There is existing 10-inch diameter polyvinyl chloride (PVC) <br />trunk sanitary sewer along the south side of Vicky Lane and 21-inch diameter PVC trunk sanitary <br />sewer along the east side of Lake Drive (CSAH 23). City records do not indicate the invert elevations <br />of the sanitary sewer manhole closest to the proposed development. Elevations will have to be field <br />verified before design can be completed. <br />The 2040 Comprehensive Plan does not identify any future trunk lines in this area. The development <br />would have to connect to the existing trunk sanitary lines on Vicky Lane or Lake Drive (CSAH 23). It <br />is feasible to extend sanitary sewer through this development. All proposed units will be required to <br />connect to the City’s sanitary sewer system. <br />•Transportation <br />The Villas on Vicky is located at the southwest corner of the existing Vicky Lane and Lake Drive <br />(CSAH 23) intersection. Vicky Lane is a 2-lane residential street and Lake Drive (CSAH 23) is a <br />county state aid highway. In this area, Lake Drive (CSAH 23) has 2-lanes with a striped center gore <br />and paved shoulders. The concept plan includes realigning the Vicky Lane and Lake Drive (CSAH <br />23) intersection so that the entrance to Vicky Lane aligns with Kelly Street on the east side of Lake <br />Drive (CSAH 23). This realignment would include curving Vicky Lane so that the proposed portion <br />runs parallel to Lake Drive (CSAH 23) for approximately 200 ft. A private drive is planned to connect <br />to Vicky Lane in two different locations. <br />Anoka County reviewed the development and they will require that the existing right turn lane on <br />southbound Lake Drive (CSAH 23) be extended to the proposed intersection. Anoka County also <br />reviewed the need for a designated left turn lane on northbound Lake Drive (CSAH 23). A left turn <br />lane will not be required at this time as it would have significant geometric and construction impacts <br />on Lake Drive (CSAH 23) and surrounding streets and properties. <br />Based on the review of the Villas on Vicky Concept Plan the following was concluded: <br />•The Concept Plan is generally consistent with the Transportation Section of the City’s <br />2040 Comprehensive Plan. <br />•A Traffic Impact Study (TIS) should be completed to document the traffic operational <br />and safety impacts of the proposed development. <br />•City Standard Details state that residential streets included in a PUD must be at least <br />30-ft wide from back-of -curb to back-of -curb (B-B). The plans currently show a road <br />width of 28-ft B-B. <br />•Staff does not recommend that the city approve layout of the Vicky Lane and private <br />drive as currently proposed. The southern intersection of the private drive and Vicky
