� <br />6.0 STAFF COMMENT — PUBLIC WORKS ENGINEERING: <br />6.1 On October 23, 2007, the Public Works, Environment, and Transportation Commission <br />met to review the Har Mar Proposal. The following are their suggested conditions of <br />approval: <br />a. Staff should review whether there are domestic water supply wells within one <br />quarter mile of the infiltration basins to determine if there are potential <br />contamination concerns and require monitoring wells if water supply wells exist. <br />b. Staff should review the soil boring information for determination of soil <br />suitability for infiltration of storm water. <br />c. The applicant's traffic study should be revised per the recommendations of the <br />city's reviewing consultant dated October 23, 2007. <br />d. The applicant should develop a pedestrian and bicycle access plan. <br />e. The applicant's traffic consultant should determine if there are ways to mitigate <br />traffic flow toward the Snelling Avenue and County Road B intersection. This <br />intersection is near a failing LOS. <br />6.2 Staff has completed additional review on the first condition to better understand the <br />existing regulations regarding domestic water supplies. As a part of the applicant's storm <br />water management plan, they are required to construct infiltration areas. Underground <br />infiltration galleries are considered Class V injection wells. As such, the owner is <br />required to register these wells with the US Environmental Protection Agency. They are <br />also required to comply with Federal underground injection control program regulations. <br />These regulations require the owner to construct and operate the well in a manner that <br />does not endanger underground sources of drinking water. <br />6.3 There are 6 residential domestic wells located between 1,000 and 1,350 feet away from <br />these infiltration basins. Residential wells are regulated by the Minnesota Department of <br />Health. <br />6.4 Staff feels that requiring the applicant to install monitoring wells implies that the City <br />will monitor these infiltration areas. Since wells are regulated by state and federal <br />agencies the City code does not regulate wells. As a result staff does not believe that this <br />should be added as a condition of approval. We will make the applicant aware of the well <br />requirements as a part of our review process. <br />6.5 The remaining 4 conditions are consistent with City Code and staff requirements. <br />PF07-0�3_RPCA_1 10707.doc Page 4 of 12 <br />
