With the exception of chemx^ algae control all <br />of the above BMPs have been incorporated into the project as p^ ot the draf <br />coooeradve agreement between the MCWD, the cities of Long L^e, Orono, and <br />MeSia and Hennepin County. Site-specific numencal water qu^ty goals for Long <br />Lake were developed in conjunction with the MPCA. To meet the implementauon <br />coal both intemal^d external phosphorus loadmgs must be substanaaily reduced. <br />To reduce external phosphorus loading sigmricant wet detention pondmg at both the <br />CouiS' Road No. 6 and the Deer Hill Road sites is required. Due to econoimcs and <br />Sal Constraints, the overall pond areas have been reduced somewhat from uhe <br />S^d feasibdltv study. Therefore, it is important that the remaining proposed <br />^ be'constructed so as to not funher reduce water quality projections for <br />Long Lake below the original water quality goal. <br />Durina the planning and design phase of the project an exhausd^analysis was <br />completS which evaluated aU altemadve detention pond sites.
