Ridgewood Hills Preliminary Plat Page 2 <br /> January 23, 1996 <br /> • Background <br /> The eastern 80 acres of the subject property went through an administrative <br /> subdivision in 1993. The application included subdividing the northeast 10 <br /> acres and leaving a 70 acre parcel. The 10 acre parcel is not included in this <br /> preliminary plat request. <br /> Wetlands <br /> In order to gain access to the developable portion of the parcel, approximately <br /> 1.7 acres of wetland will need to be filled. In accordance with the State <br /> Wetland Conservation Act, the developer will be required to mitigate at a <br /> ratio of two to one. Therefore, approximately 3.4 acres of new wetland will be <br /> created to offset the requested fill activity. <br /> Approval of this proposed plat will be conditioned upon receiving the <br /> appropriate wetland permits from the city and other agencies. The City's <br /> Technical Advisory Committee is reviewing the wetland mitigation and will <br /> be forwarding a recommendation to the City Council in February. <br /> Minimum Lot Size <br /> • The A-1 zoning district requires a minimum lot size of ten acres or a density <br /> of 4 per 40. Based on 110 acres included in the plat, if possible, 11 lots could <br /> be created. If the density option is selected, which the developer has, the <br /> minimum lot size is 2 1/2 acres with at least 1 acre of upland area for a <br /> house, two septic sites and a well. <br /> When determining a minimum lot area, wetland types 3 (Inland Shallow <br /> Fresh Marshes), 4 (Inland Deep Fresh Marshes), and 5 (Inland Open Fresh <br /> Water) are not included in the calculation. The type of wetland impacting <br /> lots 1, 2, and 3 is a type 2 (Inland Fresh Meadow) and 6 (Shrub Swamp); <br /> therefore, the wetland can be used in determining the total lot area. It <br /> should be noted that all three of these lots have the minimum 1 acre of <br /> upland as previously mentioned. <br /> Streets <br /> The proposed road off of Jarvis will continue through the plat to the western <br /> limits. Extending streets to the plat's limits has been done consistently on <br /> plats in recent history. <br /> • The street section that will be used is a 32 foot wide rural street with <br /> bituminous curbs. County Road 24, (Jarvis Street) is a Anoka County <br /> s:planning:pc:p95-9 <br />
