• MINUTES OF THE ORONO PLANNING COMMISSION MEETING HELD ON APRIL 21, 1997 ( #14 - #2209 Spring Hill Golf Club - Continued) Gaffron said the drainfield area designated on the site plan is suitable for a single mound system. A secondary site will need to be located elsewhere outside that designated area. Schroeder inquired about the septic system for the main club house. Gaffron said the existing conference center septic system will be used and is adequate. Gaffron reported Staffs recommendation is for approval conditioned on receipt and Staff approval of the maintenance facility site evaluation plan. Commissioners agreed 6/0 in favor of the recommendation. (MG) Ground Water - Gaffron indicated water supply is not anticipated to be a problem for the site. The existing well is 178' deep, cased down to 143. An EAW comment requested the applicant be required to perform ground water modeling studies to predict the impact of the golf course's irrigation water appropriations on the local water supply. Gaffron felt it was appropriate to address this issue. Hydrologist, Ken Adolf reviewed the expected impact from the existing irrigation well on the south side of the conference center. The analysis had assumed a 750 gpm radius, although the well is rated at only 500 gpm. The influence would be a radius of 950', and • no wells are located within that distance. He indicated a majority of neighboring wells are bed rock wells. A drift well is to be used for the irrigation system. The result is that there will be no influence between this well and other wells. Braman commented on the depth of the well. Hennepin County staff had noted a discrepancy in the reported well depth. While the well was drilled to a deeper level, it was found that formations higher up were better and the well was grouted to make use of the shallower aquifers. Commissioners accepted applicants information as fulfilling the Staff recommendation. (EM) Storage of Fuels and Agricultural Chemicals - Gaffron reported an above- ground fuel storage system will be installed at the site meeting all pertinent code requirements. Class I and Class II chemicals will be stored in this secured building and labeled "caution" and "warning ". These chemicals are used for plant protection, regulators, and chemicals typically used for golf courses. Schroeder inquired how much chemicals would be used or budgeted for use. Tim Johnson said their budget is $20,000- $40,000 per year. isCommissioners agreed 6/0 with Staff recommendation subject to appropriate permits. 22
