RWSA has serious concerns regarding the grading over the RWSA sewerline for Road B and the proposed box culvert for the crossing of Morey Creek. The proposed grading would put a significant amount of fill over the RWSA sewerline and the proposed culvert would concentrate the stream flow over the sewerline. RWSA is still evaluating the impacts to the sewerline, but these issues will need to be resolved prior to site plan approval. Possible solutions may include replacement of the sewerline with ductile iron pipe. 2. RWSA would like to minimize the number of connections to the RWSA sewerline. It appears that the connection off Road B may be able to connect to the existing ACSA sewerline. The other connections to the RWSA sewerline should be modified so that they connect to an existing manhole. 3. RWSA is requesting a 60' wide easement, centered on the existing RWSA sewerline, across the entire property. RWSA is also requesting a rectangular easement that will be between the edge of lot 1 on the west and the edge of the electric line easement on the east and extend 100' south of the railroad r/w on the southern edge. RWSA is still working to determine the exact location of this easement. 4. RWSA will need to review and approve the final site plan. In addition to the comments above, additional notes will be required on the final site plan for the water and sewer connections and the landscaping and stormwater management plans may need to be modified so that the RWSA facilities are not adversely impacted. Unfortunately, neither Justin nor I will be able to attend the meeting tomorrow, so you may contact me with any questions or concerns either by email or on my cell at 906 -2813.
