January 22, 2025 Planning Board Special Meeting Minutes

the wall is about another 15 feet to the property line. In total, it is about 80 feet from the property line to the pool. Mr. Guarino asked was there a measurement made of any additional storm water runoff into the municipal storm source. Mr. Cokeley said no, everything drains away from the municipal storm source. Mr. Guarino asked was there any considerations in putting any storm water from the back to the municipal storm water to lessen the flow onto anyone’s property. Mr. Cokeley said drainage calculations are done to mimic the existing conditions. The site flows towards the other property. By bringing storm water to the municipal system in Eagle Ridge Way, that would contribute more water runoff but also more challenging as storm water would need to go uphill. Chairman Bagoff asked did you have any comments about the 36-inch pipe that now faces Llewellyn Park from his property and the water runoff, is it more, less, or about the same as previously said to occurred. Mr. Cokeley said he doesn’t know because he doesn’t have a survey that includes the 12-inch pipe that was there. Chairman Bagoff asked do you think it makes sense in the overall project to address that pipe that flows from Crystal Point to Llewellyn Park traversing 40 Eagle Ridge Way. Mr. Cokeley said the outlet control structure that Mr. Cohn asked them to do does address it in some way. It is essentially mimicking 2 12-inch pipe to best they can. Chairman Bagoff asked is your testimony that based on the way the storm water management will be accommodated in your project, the flow from Crystal Point through 40 Eagle Ridge Way, the water will be decreased to Llewellyn Park. Mr. Cokeley said no they didn’t look at Crystal Point He said that his testimony and what the report shows is the storm water runoff from 40 Eagle Ridge Way to the neighboring property is going to be reduced in compliance with the regulations. Chairman Bagoff asked can you agree that all the requests in the Matrix World Engineering Report of November 26", 2024 will be agreed to by the applicant. Mr. Cokeley said the only one he mentioned before is the architectural plan and then the rest will be addressed. PROFESSIONALS QUESTIONS Mr. Scott asked is there anything in my letter that you have any issue or have a problem addressing as part of our review. Mr. Cokeley said they do not. Mr. Scott asked in terms of the

ALS QUESTIONS Mr. Scott asked is there anything in my letter that you have any issue or have a problem addressing as part of our review. Mr. Cokeley said they do not. Mr. Scott asked in terms of the outlet control structure and scour hole, how is the outlet control structure going to be working without having a storage mechanism to hold back the water. Mr. Cokeley said they were looking at it from a perspective if there were 2- inch pipes here before what could they put in place to closely mimic that situation as closely as possible so the outlet control structure consists of 2 10-inch outfalls to mimic the prior drainage pattern. The scour hole was per SCD direction. Mr. Scott asked do you have any information prior to the SCD coming in and making the request to put in the elliptical pipe. Mr. Cokeley said he doesn’t. Mr. Scott asked has there been any calculations or analysis of the ditch like what kind of flows that can be anticipated during any type of storm events. Mr. Cokeley said they looked at strictly from this site and in their design and drainage area maps it is part of the 40 Eagle Ridge Way that goes into the ditch. From the analysis of 40 Eagle Ridge Way property, it is going to be a reduction getting to that ditch. Mr. Scott asked in your revising of your plans, did you do any calculations to show what that reduction is. Mr. Cokeley said he believes their storm water report includes analysis a3 different design points one of which is the ditch and they can extract that out and 13
