Box 490 <br /> Elk River, MN 55330 <br /> RE: GRACE ASSEMBLY OF GOD CHURCH <br /> SITE PLAN REVIEW <br /> Dear Mr. Ach: <br /> CIVIL ENGINEERING: As requested, we have reviewed the submittal for the Grace Assembly of God Church. <br /> ENVIRONMThe packet we reviewed was prepared by Robert Baker, Architect, and dated May 28, <br /> "'MUNICIPAL 1996. Based on our review and comments received at the staff review meeting, we would <br /> PLANNING offer the following comments: <br /> SOLID WASTE <br /> STRUCTURAL 1. On the interior of the parking lots, the double row of parking, the City ordinance <br /> SURVEYING requires a depth of 20 feet on each stall for a total width of 40 feet. These double <br /> TRAFFIC rows of parking are currently shown as 36 feet wide. <br /> TRANSPORTATION <br /> 2. At the south end of the parking area, a drive isle should be provided around the <br /> ELECTRICAL/MECHANICAL parking rows. <br /> ENGINEERING: <br /> HVAC 3. The grading plan shows all drainage being funneled to the southwest corner of the <br /> POWER DISTRIBUTION <br /> parking lot where it is discharged through an opening in the curb that is rip-rapped. <br /> SCADA <br /> We would suggest that it would be better to install catch basins and small diameter <br /> SYSTEM CONTROLS <br /> storm sewer to convey a run-off to the proposed storm sewer pond. <br /> 4. Grading along the east and south property lines indicate that the CSAH 13 drainage <br /> will be conveyed through a culvert under the driveway and along a proposed swale <br /> south of the parking area to the proposed pond on-site. We question whether or <br /> not the pond is adequately sized to take all the drainage along the CSAH 13 ditch. <br /> At some point in the future, we will need to see drainage calculations that show the <br /> tributary area north of the culvert, provide documentation that a 15-inch culvert is <br /> satisfactory, and provide inverts for that culvert. <br /> •OFFICES IN: <br /> MINNEAPOLIS <br /> PRIOR LAKE <br /> ST.PAUL <br /> WASECA <br /> An Equal Opportunity Employer <br />
