IOPPENHEIMER WOLFF FOSTER SHEPARD AND DONNELLY Mayor and Council Members May 3, 1982 Page Two 1. The PRD Complies with the Intent of Orono's_ Hard Cover Reaui cements . The intent of hard cover requirements is to control problems with water runoff, whether it be the amount of runoff or the pollution of runoff. It became apparent in the late 1960's and 1970's that a problem was developing in Lake Minnetonka concerning the intensive development of land and detrimental effect on the City and on the water quality of Fake Minnetonka. Uncontrolled development of houses, and perhaps even more so the uncontrolled addition of large garages, patios, tennis courts, parking_ lots, and other hard cover created special problems. As a result of those concerns, both the DNR and the City of Orono undertook studies to deterrrLne the impact of hard cover. s a result, Orono passed an ordinance which limits the amount of hard cover on a lot, thereby controlling; and minimizing the impact of undcc;irable quantity and quality of runoff into Lake Minnetonka and the City of urono as a whole. The PRD of Baldur Park developed by Ernst Associates complies with this intent of the hard cover ordinance. After careful engineering, a system of holding ponds have been developed, such that devele-)rr.ent of the four-tuilding site will result in no additional runoff which__ presently exists on the site. In other words, these holding ponds keep the runoff situation on Baldur Park in status quo. The fact that the professional engineers and City staff have developed a system to prevent additional runoff in order to comply with the intent of the hard cover ordinance should be given great weight by the City Council and Mayor. 2. The Unique Shape of the Baldur Park Peninsula Poses —a Particular Hardship on Tonka Lake Properties. Strict application of the Orono ordinance, in this case, poses a particular and unique hardship upon development of the peninsula from the standpoint of hard cover requirements. This .is so because this particular land happens to have water on three sides, rather than just one front side as in the case of a "typical" building s�te. An example illustrates this unique problem. Assume, for a moment, that the 2.7-acre site on Baldur Park was situated such that there was water on only on- side of the pro- perty (P.q. the South side). Assume, too, that the 2.7-acre site drained -otally towards the Lake on that one side (as it virtually does now anyway), so that the amount. of runoff that presently
