The water level of the pond will be controlled by two cul- verts. The applicant has not provided information as to a spacific elevation for culverts but they must be so placed as to not create blockage of drainage on Lot 4. The pond wi 1 1 be 4 1/2 feet at its deepest point. An aerator will be installed to control growth of algae and unwanted vegetation. The pond is decorative and will not function as a wildlife pond, thus no need for DNR review. The watershed involved is localized and does not qualify for watershed review. The City Engineer has reviewed the pond and the surrounding properties and has the following comments: A. In regard to bank slopes, he advises no changes but to let them seek their natural grade. The spoils on the northwest side of the excavation must be used to trim banks along west and north sides of pond (use same slope ratios for banks as found un southern pond;. B. As soon as final grading is completed, the entire disturbed area must be seeded with appropriate ground cover. C. The City will ask for a drainage easement to reflect the drainage pattern/flow at the time banks of pond are re- stored. The drainage easement of 20 feet will assure that the applicant or a future owner will not block the culverts taking immediate drainage from Lot 4 to the south. The drainage easement will secure the natural drainage flow to the west (in this case probably northwest). Normally we would have required elevations of culverts but in light Df the localized nature of the watershed, the City need only >>e concerned that a drainageway be defined and protested via the easement.
