THEWAYMAKER LETTER OF EXPLANATION AND G COMPLIANCE

Application: © THEWAYMAKER LLC Block 106 Lot 20.03 40 Eagle Ridge Way Submitted: September 18, 2024 township engineer opined’ for the first time that because of the extended construction activity, the construction had become a Major Development for which a Major Development Site Plan application must proceed. Notwithstanding a commitment to restore grades and bring the boulder wall into compliance, the township engineer asserted that the process requires a Major Development Site Plan, not an ultimate, good faith result, even though all work was permitted and inspected. A request for a waiver was denied and this Application proceeds to address that directive of the township engineer to file a Major Development Site Plan Application for a single family house. THIS APPLICATION As a Major Development, the State Regulations and West Orange Code requires additional stormwater collection which has been designed by Colliers Engineering to be placed underground in the rear yard. Certain drains from the impervious areas will be redirected to the new proposed system and a curtain drain has been designed to collect the surface stormwater. Asa result of the proposed designs, the original grades on the property will not be completely restored. While the grading will be generally close to the pre-existing grades, in order for the curtain drain to be most effective, the grading has been modified for maximum collection. Additionally, there is a pre-existing drainage ditch on the property that serves to transport stormwater from off-site sources on and abutting Eagle Ridge Way as well as the stormwater from the subject property adjacent to the ditch. The Owner maintains Lot 40 and keeps the ditch free of debris and replaced the two parallel clay pipes that were in disrepair with a single concrete elliptical pipe and at the recommendation of the HEPSCD, put riprap in the ditch to stow and control the water flow, even though the water does not originate on Lot 40. An outlet control chamber’ is proposed to be installed at the start of the previously installed elliptical pipe and a scour hole will be placed at the outflow end of the elliptical pipe prior to the stormwater following its natural path over the mountain to follow the pre-existing drainage ditch that continues on other properties. 1 This is the same township engineer that reviewed the Drainage and Grading Plan

wing its natural path over the mountain to follow the pre-existing drainage ditch that continues on other properties. 1 This is the same township engineer that reviewed the Drainage and Grading Plan on March 6, 2023 that DPW approved and for which substantial work proceeded in reliance on that authorization, the inspections and approval. Said reviewed plan indicated the greater area of disturbance required for the new installation. In her review memo at that time, the engineer did not state that the project had now become a Major Development. 2 As set forth in the details and calculations from Colliers Engineering, this outlet control chamber will actually reduce the outflow from the elliptical pipe to a level less than the outflow from the pre-existing twin clay pipes.
