(Armstrong Blvd). A second western entrance to this development from CR 116 is permissible, however, it must be extended to the western boundary of the plat so that good public access is available to the parcel to the west. One access is proposed onto CR 56, a distance of 420 feet south of 149t~ Ave. It is in the public interest to mimmize the number of accesses on the County trunk highway system. Therefore, staff recommends that this access be eliminated. Staff suggests that the new roadway connect to 149t~ Ave. at the Peridot St. intersection. This will provide the neighborhood to the north a convenient access to the intersection of CR 116 and CR 56 which will likely be signalized in the future. Care should also be made to minimize townhouse driveways from this .roadway. The drives serving the townhomes are shown to be private and maintained by the Homeowners Association. City ordinances state that private streets shall not be allowed in Ramsey. However, past practice has been to allow them in certain developmentsl All public and private streets shall be named in conformance with the City's street grid pattern. City ordinances call for sidewalk to be installed on all roads except cul-de-sacs. The concept plan does not show any sidewalks, Lots: The single-family lots do not have dimensions on them, but they appear to meet minimum lot standards. Staff will review these lots in greater detail at the preliminary plat stage. Staff needs clarification on the status of the large lot in the northeast part of the property shown in the sketch plan. You have indicated that this area is an exception to the plat, but City records do not show it as a separate lot. Performance Standards: The PUD development agreement will establish appropriate Performance standards relating to setbacks, lot coverage, .-landscaping, parking, screening, architectural standards, minimum floor areas, etc. Grading and Drainage: A grading plan is required at preliminary plat stage. The sketch plan shows two ponds into which stormwater ~vill be collected in pr/or to overflowing into protected wetland 671W. A permit for erosion control and stormwater management will be required from the Lower Rum River Water Management Organization (LRRWMO). It should be noted that wetland 671W currently does not have an outlet, therefore building pad elevation wilt need to be designed to accommodate back to back 100-year storm events. Further information will be needed for the grading and drainage plans at the time of preliminary, plat review. Wetlands: The sketch plan proposed to fill approximately i/3 of an acre of wetland adjacent to DNR protected wetland 671W. A permit for wetland filling will need to be obtained from the Lower Rum River Water Management Organization (LRRWMO). The plan must address sequencing for wetland fills which includes avoidance, minimization, and mitigation of the wetland. It would appear that the wetland fill could be substantially minim/zed by eliminating two of the eight townhouse units.
