Gjffron Assistant Building and Tuning Administrator City of Orono Post Offici* Box 66 Crystal Bay. Minnesot.i 55323 Rc Garden Lane Site Sketch Plan File No, 139-2239 Dear Mike. We have reviewed the sketch plan prepared for Jim Waters on the proposed Garden Lane Site, a seven-lot .subdivision of Lot 2. Block I. Heatltercroft and Lot 90. Tonkaview Ga.'dens. located west of Wildhuisi Trail in the west half of Section 7 Thc.c are several issues ihut need to he addressed relative to engineering matters and included with the plan 1. UtlUtles: A sanitary sewer will need to be extended north along WildhurM Trail approximately .310 feel to the adjoining lot line l>etween Lots 5 iu.J 6 and then westerly and northerly to the end of the northerly cul-de-sac. Sewer seA’ice an be provided from Tonkaview Lane. However. 200 feet of existing sewer must be replaced at greater depths Plans and speciflcatiuns should be prepared for the sanitary .sewer and street reconstruction of either Tonkaview Lane or Wildhu.st Trail, with us-buili plans provided to the City upon completion. As this sanitary sewer and street will be owned tuid maintained by the City, we recommend that the design, bidding and construction be done by the City with assessments levied to the development. Please note there is no municipal water service available for this area. Each lot will be required to be served by a well. 2« Streets, The propo.sed street location appears acceptable. There should be some provision to provide street access to (he City Park north of the development. This could be done by providing a driveway to the Park from the cul-dc-sac. constructing the cul-dc-sac wahin the Park, or eliminating the cul-de-sac and creating a parking/tumarmind are.i within the Park property. The easterly cul-de-suc should drain west to a storm sewer line which would run westerly and northerly to the end of the cul-dc-sac. Drainage could be routed to the ravine on Lot 2. Plans should be prepared for the su’cei and storm sewer construction. 3. Grading: A grading, drainage and erosion control plan should be prepared that shows both the existing and proposed contours, building pad locations and elevations, and erosion control measures to he used during construction 4. Drainage: There are two major drainage ways running through the property One is located at the northern end of the site which drams northeasterly through Lot 2. The other is ItKated at the southern end of the site which dr.uns easterly through Lots 6 and 7. We recommend that the majority of the dniinage from the site be directed to north. The north nivmc gradient is half a.'^ steep as the south ravine which will allow more options to handle the stonn water runoff. .Some type of stomnvater retention and/or How reduction structure (or other type of improvement) should be installed within this ravine. 2335 West Highway 36 • St. Paul.
