• r Howard R. Green Company May 23, 2002 File: 816091J-0240 Ms. Michele McPherson Director of Planning City of Elk River 13076 Orono Parkway PO Box 490 Elk River, MN 55330-0490 RE: GRACE ASSEMBLY OF GOD CHURCH SITE PLAN REVIEW Dear Ms. McPherson: As requested, we have reviewed the Grace Assembly of God Church site plan. The items we reviewed were a site plan prepared by St. Rosa Lumber Company of Freeport, Minnesota, dated April 18, 2002, and drainage calculations prepared by Bogart Pederson and Associates, Inc., dated May 3, 2002. Based on our review of these documents and comments received at the staff review meeting, we would offer the • following comments. 1. The layout of the parking area is substantially larger than it needs to be. The three drive aisles are shown as 24 feet wide, 32 feet wide, and 38 feet wide. All three could be reduced down to the 24- foot width, which is the minimum for two-way traffic. The easterly row of parking adjacent to the curb line could be reduced to 18 feet, since there is the ability of a car to overhang the curb line. The entire perimeter of the parking area needs to include barrier concrete curb and gutter. We would suggest that concrete islands be used to define the ends of the parking aisles. 2. The access drive on to CSAH 13 is shown approximately 40 feet wide, and is not perpendicular to CSAH 13. This is too wide; the maximum driveway width for this type of development is 30 feet according to the City ordinance. Also, Sherburne County should comment on requirements such as turn lanes or bypass lanes for allowing this access on to CSAH 13. 3. The sanitary sewer and water service for the proposed church will have to come from the west, out of the Royal Oaks Ridge development. It is unlikely that the sanitary sewer is deep enough to service this church by gravity means; therefore, the church will need to provide a pumping station and forcemain to get sanitary sewer flow over to the existing sewer line. The proposed plat of the development includes a drainage and utility easement through the entire site. Bryan Adams, General Manager of the Elk River Municipal Utilities, intends to eventually loop watermain from Royal Oaks Ridge to the trunk line in CSAH 13. Perhaps this looping of the watermain could happen concurrently with providing service to the church location. In addition, at least one hydrant will need to be strategically placed on the site for fire fighting purposes. The most likely location would be in the concrete island defining the closest row of parking to the church building. It is likely additional hydrants will be needed if the future additions are built. If all the hydrants are to be installed with this • first phase, a meeting with the Fire Chief to determine location will be necessary.
