The church is conditional use in the Rural zoning ordinance. An Environmental Assessment Worksheet was prepared in 2002 for the project prior to it's start up. Planning and Zoning made recommendation to allow the conditional use. Terms of the Conditional use can be found in (Attachment 1). Eagle Brook Church was built in 2005. The church is now asking for a permit to build an additional parking lot to accommodate increased church membership. The parking lot is located in the SW parking area of the site and was graded in the initial development process to accommodate more cars. According to Eagle Brook Church the area is used as overflow parking now but turns to mud during wet weather. The church wishes to pave the overflow parking area. The original development created an impervious cover of approximately 15 acres and was permitted by RCWD. Analysis: This project falls under the new RMP -3 rule. The expansion area location is depicted in Attachments 2 and 3. The expansion would increase the amount of impervious on site approximately 1.7 acres. The new parking lot expansion area was not considered in the RCWD permit at the time of church construction. The findings of the RCWD can be found in Attachments 9, with the RMP -3 rules listed on Attachment 10. The following Findings are listed in the CAPROC report of the RCWD: Stormwater —The project is subject to section 8 of the RMP -3 The rule requires the retention of runoff from a 2.3 -inch rainfall by infiltration practices if possible. If infiltration is not feasible, the requirement must be achieved by bio- filtration or two -cell wetland treatment system. Volume control is also required for an additional 0.5 inches of wetland treatment system by measures specified in 8C of the rules (Attachment 10).This requirement is subject to the Volume Credits rules of Section 9 of the RMP -3 In regards to this requirement the applicant is proposing to provide an upland area in the existing conservation easement on the SW corner of the site. The existing conservation easement was not a RCWD permit requirement when the church was built. The upland conservation are must meet the requirements of the RMP -3 and be of high quality
