GENERAL T,eekley's Inc., of Wayzata is currently constructing two single family residences along C.S.A.H. 6 in Orono. The property is described as Lots 2 and 3, Block 1, Willow Run Addition. This development is located in the southeast quarter of Section 28, Town- ship 118 North, Range West. Leekley's has requested the City of Orono to authorize the construction of a shallow excavated pond on each of the two subject lots. since the City of Orono has not officially adopted any guide- lines or regulations pertaining to the construction of ponds, Leek- ley's was referred to the Hennepin Conservation District to conduct an analysis and provide reconunendations for the requested ponds. The following presents those findings and recommendatio,,s made by; the District. FINDINGS A site inspection conducted on Monday, July 30, 1984 revealed the lot size for Lots 2 and 3 to be approximately 3.65 acres each (see Figures lA and 1B). The lots utilize a single access driveway from C.S.A.H. 6 along their common property line (see Figure 2). Both lots are generally open, with grass cover consisting primarily of bromegrass, reed canary grass, and bluegrass. Accurding to the soil survey of Hennepin County, the lower elevations of the two subject lots contain Glencoe silty clay loam soils while the higher eleva- tions consist of Le Sueeur loamy soils. Glencoe soils have high avail- able moisture capacity, very slow internal drainage, and moderate to moderately slow permeability. The water table is near the surface during wet seasons. Le Sueur soils have high available moisture capacity. They have moderate permeability and medium internal drain- age. The water table is at a depth of 3 to 5 feet during wet seasons.
