The plan will need to be reviewed and permitted by the Lower Rum River Water Managemem OrganiZation. Care should also be given toward locating the pond inlets in close proximity to one another to facilitate cleaning. The inlets and outlets should be placed as far as possible from one another to improve nutrient removal efficiency. Consideration should also be given for creating an outlet to access the inlets for sediment removal. There also appears to be ex'tensive use of rear Yard drains. There are nine such structures on th/s proposed plat. An effort should be made to reduce the use of rear yard drains as, like any storm drain, they are subject to freezing and subsequent flooding. Several locations along the perimeter of the subdivision propose slopes as steep as 20%, one foot vertical to 5 feet horizontal. It appears these grades are necessary to accommodate walkout or lookout iots. Consideration should be given toward modifying these areas to flatten slopes and restricting the development to rambler type homes on these sites. No grades shall be flatter than 1%. Grades flatter than 2% will require a certificate on grading prior to an occupancy permit being granted. Tree Preservation. In accordance with City Code, the Preliminary Grading and Erosion Control Plan does identify ex. isting tree growth and removal limits. The addition of one 2.5 inch dbh tree to each lot should also be identified on the Plan. Sidewalks. In accordance with City Code, sidewalks are proposed on one side of all non cul- de-sac streets. There is also a sidewalk connection proposed from the terminus of Waco Court N.W. to Bear Park. Trail Development: There is also a trail development fee of $325 per unit that must be paid prior to release of the final plat for recording. Stormwater Management: The City has established a storm water management fee of $375 per unit that must be paid prior to release of the final plat for recording.
