As I indicated in my facsimile dated March 16, 1995, the City Engineer has surveyed the CIVil ENGINEERING: topography of the site and observed the site to determine the possible cause of Mr. Aiken's ENVIRONMENTAL concern. I ~IPAl LANNING Based upon our records for the lot split, a drainage swale was to be constructed under the SOUD wASTE agreement with the Developer (Mr. Tom Wegleitner). Several letters were sent to both the I STRUCTURAL City and the Developer regarding the issue. These letters were dated December 4, 8, and SURVEYING 29, 1989. Based upon the resulting grading plan submitted by the Developer, a drainage TRAfFIC swale was to be constructed from the pond to culverts north and east of the developing lots, I r~ANSPORTAT10N (see attached). The bottom of this swale should have provided an outlet for the pond at an ELECTRICAL/MECHANICAL elevation of 875.2 feet above mean sea level. Our survey of the site indicates that the I ENGINEERING: swale drains west into the pond rather than east from the pond. The pond would have to HVAC reach an elevation of approximat0pt in order to actually begin to drain. POWER DISTRIBUllON 11S: I SCADA Based upon our review of the situation, it appears that the City should rectify the problem SYSTEM CONTROlS by having the drainage easement graded along the back lot lines of parcels A and B adjacent to Amble Road. This should be done in accordance with the Developer's original grading I plan, if possible, at the Developer's expense. We should note that it may be difficult for the City to force the Developer to correct this issue at this point. We would also I recommend the City allow Mr. Aiken to place up to 40 cubic yards of fill behind the existing pond easement, up to the 976 elevation. This would allow the pond to drain to the east prior the pond encroaching the Aiken property. It may be beneficial for the City to I j:"''' utilize its own Public Works staff to complete the placement of fill on Mr. Aiken's property to reduce the costs of such work. NEAPOlIS I PRIOR LAKE 51.
