Minnesota 55323 <br />r' «1VED <br />MAY 9 1994 <br />C. r OftONO <br />Re: Liljequist V'ariancc <br />File No. 13s 1904 <br />Dear Jeanne, <br />We have inspeaed the propern- and rcsicwxd the certificate of survey submitted with the <br />variance application for the proptiscd house on Eric & Shelly Liljcquist’s property. The <br />inlormation shows that the proposed house will require approximately 625 cubic feet of fill to be <br />placed within the flo<>dplain of Lake Minnetonka. The applicant has proposed to excavate <br />approximately 6 inches over a 36 feet by 35 feet area adjacent to Birch Lane as compensatory <br />fltxidplain storage. We do not rewmraend this location because it is has the highest elevation on <br />the lot. To qualify for floodplain storage, the excavation must take place below the floodplain <br />elevation of 931.5. To provide the 625 cubic yards required, the propsised kKation near Birch <br />Lane wrould first have to be excavated dowm to the 931.5 elevation, then lowered an additional 6 <br />inches to create floodplain storage. The total excavation in this kKation would be nearly 2 feet <br />in depth. <br />The side and rear yard areas presently have poor drainage. It is apparent that the low areas on <br />the lot drain solely by seepage into the soil. Although the proposed improvements will not <br />increase the runoff on the property, the drainage aiuld be improved by excavating a shallow <br />ditch out to the lake. If the excavation is done cither west or north of the house, nearly all of <br />the excavation would qualify as floodplain storage. The excavation should be graded to drain <br />around the west side of the house and out to the lake shore. <br />Prior to the work, silt fence should be installed near the lake for erosion control. The disturbed <br />area should be seeded or sodded shortly after the work has been completed. We see no adverse <br />impacts on the property from either the fill placement or excavation, if it is done in this manner. <br />Please cont.ict me t this office if you have any questions regarding this matter. <br />Yours very truly, <br />BONTSTROO, ROSENE, ANDERLIK & ASSOCIATES.
