Other methods <br /> for reduction of phosphorus have been reviewed by the Watershed District <br /> and do not appear feasible. Therefore it appears that use of a N[TRP �ond <br /> based on the Wa�ker mod'el is eapected to be an effective method of <br /> phosphorus reduction for this watershed. <br /> g. The location of the propqsed detention basin is appropriate because it is <br /> located betvveen the outlet of the creek to Long Lake and the co�ifluence of..;i,. <br /> the two creeks from Medina;�because it avoids excavation on wooded hills • <br /> with steep slopes north of County Road 6 which «�ould have a significant <br /> impact on the adjacent residential properties and potential impact on <br /> Wolsfeld Woods Nature Area; and because it avoids the need for excavation <br /> or alteration of the signific�nt Type III wetland located directly upstream <br /> from the creek outlet at Lo�rg Lal:e. <br /> h. While the site is adjacent to residential properties;the location will be heavily <br /> screened from surrounding houses by existing veaetation. The primary visual� <br /> impacts will be fi•om County Road 6. The proposed site is adjacent to <br /> Count.y Road 6 which enhan;.es ease of the construction and long-term poncl <br /> � maintenance. . <br /> Page 3 of 14 <br />
