MIHUTBS OF THE PIAKHIliG CONMISSIOH mcSTING SBPTBfBBR 19* 1988 II >1lOHIMG PILE #1330-POLLERTON PEOPBIKTIES COWTIW The Mr. Joseph Franks was present for this matter. Assistant Planning and Zoning Administrator Gaffron explained that the subject property is located within the 5-acre minimum zone. Applicant is proposing a 7 lot residential subdivision with a private road. The lots would be served by an interior private road. There would be no access off of Townline Road. There would be three lots that would require a variance to the 300' width standard. Lot 2 would have a defined width of 285' at the setback line; Lot 4 would have a defined width of 175' and Lot 5 would have a defined width of 150'. The proposed road length is 1,000' with a 50' outlet with a 100' cul de sac. The paved road section is proposed as urban, which would provide curbing as opposed to shoulders. A 24' paved width is proposed, but Orono code does not specify requirements for seven lots. The City Engineer has suggested 28'. The point where the private road would access Townline Road is directly across from a private road in Independence. Lots 3 and 4 are proposed to cross Painter's Creek. Staff recommends a single shared creek crossing point adjacent to the cul de sac, at the shared lot line. The applicant was now requesting 2 driveway entrances for Lots 3 and 4. Mr. Mark Gronberg, the applicant's surveyor, explained that the Minnehaha Creek Watershed District installed a weir on the property. The flows coming through the property are only 9 cfs and the culvert requirements are much less than the size of the culverts that currently run under County Road 6. The MCWD has no objections to the proposed 2 creek crossings. Chairman Kelley asked if the Minnehaha Creek Watershed District maintained that area. Gronberg replied affirmatively, and added that the MCWD has certain rights and an easement from the County to access that location. Kelley inquired as to the maintenance performance of the MCWD. Gronberg stated, "it looks pretty good in there". Gaffron showed were the Watershed District's easement was located in respect to the proposed subdivision. Gaffron asked the Planning Commission members to refer to a letter from the City Engineer wherein he requested that the storm sewer outlet be 958 rather than 961.0. Buildability of each lot was the next concern. Gaffron stated that each lot contains 1 1/2 - 2 acres with slopes of 6% or less. Mound-type septic systems would be necessary on most of the lots, due to high water table soils. Gaffron is concerned about Lot 2 because the Soil Survey may be incorrect in its depiction of where Hamel-type soils are located. Gaffron requested that soil borings be completed to better determi;ie the soil content of Lot 2. Chairman Kelley asked Mr. Gronberg if he had any other plans prior to this proposal? Gronberg responded, that there were, but one of the main things they wanted to do was access directly
