PAUL <br />WASECA <br /> <br />As requested, we have reviewed the submittal for the Grace Assembly of God Church. <br />The packet we reviewed was prepared by Robert Baker, Architect, and dated May 28, <br />1996. Based on our review and comments received at the staff review meeting, we would <br />offer the following comments: <br /> <br />On the interior of the parking lots, the double row of parking, the City ordinance <br />requires a depth of 20 feet on each stall for a total width of 40 feet. These double <br />rows of parking are currently shown as 36 feet wide. <br /> <br />At the south end of the parking area, a drive isle should be provided around the <br />parking rows. <br /> <br />The grading plan shows all drainage being funneled to the southwest corner of the <br />parking lot where it is discharged through an opening in the curb that is rip-rapped. <br />We would suggest that it would be better to install catch basins and small diameter <br />storm sewer to convey a run-off to the proposed storm sewer pond. <br /> <br />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 /> <br />An Equal Opportunity Employer <br /> <br /> <br />
