Mr. Pat Klaers October 25, 1995 Page Two July 26, 1994 letter from John Oliver & Associates to Terry Maurer. Item//4 indicates spot elevations have been checked and changed to indicate the currently existing elevations. This letter is the first indication we have that the intent of the Developer is to grade a swale in the drainage easement along the back lot lines. The elevation of the swale is indicated by the spot elevations on the plans. This letter also indicates that there will be regrading in Heritage Landing between Lots 5 and 6. ~ ~ August 12, 1994, letter from MSA to Steve Ach. Item//2 questions how a swale that gets 2 feet deep at one point can be constructed along the rear lots of Heritage Landing Addition, which already have their yards f'mished and sodded. It indicates that the drainage plan will work, but it questions how they will be physically constructed, given the current status of Heritage Landing Addition. June 1, 1995, letter from MSA to Todd McLouth, John Oliver & Associates. This letter documents a discussion with Mr. Kincannon indicating that the grading has not adequately addressed the drainage in this area and needs to be corrected prior to final acceptance of Heritage Landing 2nd Addition. · June 20, 1995, letter from MSA to Steve Ach. This letter indicated that there has been a revised drainage plan in this area that will now handle the drainage and that we through our on-site inspection will make sure that this is completed according to this plan. This is the actual improvement that was made in this development. For your information, the Planning Department and Building and Zoning Department have attempted to rectify this situation on future developments by requiring the Developer to submit a letter through his surveyor, certifying that the plat has been graded according to the approved plan. At the same time, we are making spot checks of critical locations or any other areas we feel are in question. ' We have looked at ways to improve the situation along the rear lot line of Heritage Landing 2nd Addition. It would be possible to install a pipe in this location to carry the runoff from small frequency storms, while still having a small lesser defined swale over the top of the pipe to carry any larger frequency rainfall events. We have done a preliminary estimate and design of such an installation and have determined that its costs would be between $16,000-$18,000. If the City decided to participate in the cost of such an installation, I would suggest that the best scenario would be to have the Developers design and install the pipe, have the City inspect its installation, and then participate by contributing cash.
