Mr. Steve Ach <br />January 17, 1997 <br />Page Two <br /> <br />The access to this site is a 40-foot wide driveway along the lot line between Lots <br />1 and 2. This width of driveway will allow for one lane of traffic inbound and <br />two lanes outbound. Therefore, a dedicated left turn lane and right turn lane can <br />be provided. This should help to keep traffic moving in the peak traffic flow <br />times. Currently, water from the north curb line of this driveway will sheet <br />across the driveway to a catch basin located on the south curb line. There is over <br />a foot of fall across the driveway because of the general topography of the site. <br />However, we would suggest that an attempt be made to pick up drainage on the <br />north side with a catch basin to eliminate as much as possible any sheeting action, <br />due to the large volume of traffic that can be expected to utilize this driveway. <br /> <br />The majority of runoff from this site will flow to one catch basin located adjacent <br />to the pond. We question whether or not one catch basin is sufficient to take <br />drainage from the majority of the site. <br /> <br />o <br /> <br />Grading for the drainage pond needs to provide a 10-foot flat area adjacent to the <br />sidewalk and a 5-foot flat area adjacent to the curb on the interior of the lot. <br /> <br />It is unclear from the submittal package how much of the improvements to the <br />north into Lot 2 will be constructed at this time. At a minimum, the entire <br />driveway approach needs to be constructed and the parking along the north of the <br />building, which actually falls in Lot 2, should also be constructed. The grading <br />for the Heying Addition needs to make provisions on Lot 2 to eliminate any <br />potential for erosion and/or overland flow down into the Holiday site. <br /> <br />o <br /> <br />The Landscape Plan shows a number of trees that are proposed to be located in <br />the existing watermain easement on the east side of the lot. Major landscaping <br />components such as trees should not be allowed in this area. Smaller landscaping <br />components such as shrubbery would be acceptable. <br /> <br />If you have any questions concerning these comments, please call. <br /> <br />Sincerely, <br /> <br />MSA, CONSULTING ENGINEERS <br /> <br />TJM:tw <br />345-1704.jan <br /> <br /> <br />
