• Mr. Steve Ach <br /> January 17, 1997 <br /> Page Two <br /> 4. 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 /> 5. 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 /> 6. 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 /> • 7. 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 /> 8. 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 /> If you have any questions concerning these comments, please call. <br /> Sincerely, <br /> MSA, CONSULTING ENGINEERS <br /> ,r <br /> Terry J.
