PAUL <br /> <br />WASECA <br /> <br />As you requested, I am writing this letter to document our findings from investigating the <br />rear yard drainage situation between Heritage Landing Addition and Herita2e~ Landing 2nd <br />Addition. As you are aware, there is a relatively prominent swale that was constructed in <br />this area to carry drainage from the west end or: the plat to the east end. It is our opinion <br />that the drainage on the 2nd Addition had to be modified in the field because the grading <br />on the 1st Addition was not completed according to the approved grading plan. The lots <br />that abut the 2nd Addition in the 1st Addition were left high and without defined swales <br />from the rear yard to the street along their sides. <br /> <br />For your reference, I have researched our Erie and put together the following chronological <br />order of events documenting this grading problem. I have also attached copies of each of <br />these letters for your use. <br /> <br />April 15, 1994, MSA letter to Steve Ach. Item #4 indicates that there is no <br />definition of where drainage off the northerly side of the plat ends up. No <br />topography is shown for these lots along Heritage Landing Addition. Additional <br />topography is required. <br /> <br />June 15, 1994, letter from John Oliver & Associates to Terry Maurer. This letter <br />responds to the previous April 15th letter. Item #4 indicates spot elevations and <br />drainage arrows have been added to the northerly side of the plat. <br /> <br />July 11, 1994, letter from MSA to Steve Ach. Item /14 indicates that the <br />information added to the plan is in error as documented from building permits <br />issued on Lots 3-7 of Heritage Landing. Essentially, John Oliver & Associates <br />reproduced the same information for Heritage Landing that was approved, but not <br />followed during the grading process. This letter asks the question, if the drainaze <br />will work properly, and indicates the plan should be revised to show accurate <br />existing elevations. <br /> <br />230/171-2512.oct <br /> <br />An Equal Opportunity Employer <br /> <br /> <br />
