Thc advanta/~cs associated wRh platting Krypton Street N.W. as a through street _w_,o_uld include the climinatibn of the cul-de-sac, which would have been in excess of Ramscy s maximum allowable length. A second advantage would bc that the area gained from designing a through street allows the developer to plat one additional lot over the 12 previously proposed. This bridge V~ill require a permitting process with the DNR. The developer has submitted an application tq the DNR for the necessary permit. It should be noted that the costs associated with bridgingithe ditch are highly dependent upon the type of structure ultimately allowed by the DNR. ~: DNR Wetland #114*P is located on the property. The ordinary high water level (OHW) in in4icated to be 858.1 feet. Any work which changes the course, current or cross section of th~s wetland will require a DNR Protected Waters Permit. In addition, other wetlands are !known to be adjacent to DNR protected wetlands. This project should be reviewed by ithe Lower Rum River Water Management Organization (LRRWMO) for compliance w~th their standards and those of the Wetland Conservation Act. The Army Corps of Engineers should also be contacted. Grading and Drainage: A chief grading concern will be the protection of the surrounding wetland from [:rosion and sedimentation resulting from the development. Silt fence has been specified for s~iected areas.' The LRRWMO will address the adequacy of the proposed erosion control. The grading Dian, as proposed by the Developer, would have the majority of the run-off conveyed to tfi. e northeast, down Krypton Street N.W., where it would be collected by catch basins and tr~smitted to an existing sedimentation pond constructed in the Wood Pond Hills subdivision. The overflow from this sedimentation pond flows into Protected Wetland 114-P. The westernmost 250 feet of roadway will drain west and discharge into a sedimentation pond constructed forlthe Chestnut Hills 4th Addition. This sedimentation pond will be expanded to accommodate Ithe additional runoff and will need to.be reviewed by the LRRWMO for compliance with their standards. -' The developer is also responsible for providing an addendum to the grading plan to show the proposed tree ~reservafion'plan. Ramsey's Parks and Utilities Coordinator, Mark Boos, is available for cohsultafion in preparing the tree preservation plan. 8. Park Ded_icatio~:' In it's current configuration, it is anticipated that the park dedication will consist of a cas~ payment for Chestnut Ridge.
