Date: January 4, 2005 1500 Piper Jaffray Plaza 444 Cedar Street Saint Paul, MN 55101 -2140 (651) 292-4400 (651) 292 -0083 fax www.tkda.com City of Lino Lakes, Minnesota Comm. No. 13265 -002 Routing: Revised plans have been submitted providing for a single family residential development titled Vaughan Addition. The proposed development essentially provides for the construction of 5 single family homes on 3 acres of property. The property is located along the south side of Birch Street between Tomahawk Trail and West Shadow Drive, or directly across Birch Street from Rice Lake Elementary School. Access to the 5 units would be provided by the construction of a short cul -de -sac that would extend from Birch Street. The following documents have been received for review: 1. Full size and half size plan sheets prepared by Loucks Associates received by the City of Lino Lakes December 23, 2004 as follows: Site Plan (C2 -1), Grading, Drainage, and Erosion Control (C3 -1), and Right Turn Lane (C2 -2). 2. Hydrologic Calculations, submitted by Loucks Associates and received by the City of Lino Lakes December 23, 2004. The following comments are provided.: Grading, Drainage, and Drainage Calculations 1. The revised drainage calculations are currently under further review. The calculations are based on the assumption that all hard surface areas (Area 4S, which includes all houses, driveways, and streets), will all be directed to Pond 7P, which may not be possible unless all roof drains are discharged directly to the driveways at the front of every house, which may be difficult. The Developer must demonstrate that no additional runoff beyond the existing runoff rate may be discharged from the site, especially along the west boundary of the property. Flood elevations for the adjacent wetlands must be shown on the grading plan. 3. The types of housing units are all shown as full basement walls outs, and floor elevations are provided. An emergency overflow location and elevation of 895.0 is also identified on the plan. All housing units • must meet the City's minimum requirements as follows: The lowest floor must be a minimum of 2 feet above the adjacent 100 -year pond/flood levels, 4 feet above normal pond and ground water levels, and the lowest opening must be at least 1 foot above the nearest emergency overflow elevation.
