Box 324 Wappingers Falls, New York 12590 Reference: Keenan Acres Dear Board Members: I am in receipt of the above referenced plan dated November 11 th, 1999, Sheets No. C-1 through C-3, and advise the following: 1. This is a submission of a subdivision of a 24:t acre parcel into twenty (20) lots at the intersection of Pye Lane, All Angels Hill Road and Vorndran Drive. The parcel is located within the Phase 3A, Wappinger Sewer TransmissionlTreatment Improvement, which has been authorized and is in design at the present time. The parcel is also located within the Central Water Improvement Area. The Applicant is aware that the water supply to the Central Wappinger Water Improvement is being improved at the present time to allow for this development and other developments to take place. The Applicant is proceeding with the subdivision review in hopes that when the review process is complete, the water issue will be clarified. 2. The Owner of the parcel and the Applicant of the project appear to be two different groups. The proper legal document will need to be filed with the Town of process this application. 3. Certification by a Licensed Land Surveyor of the property and topographic survey will be required. 4. With respect to Sanitary Sewer: . The Property is located within Phase 3A of the Wappinger Sewer TransmissionlTreatment Improvement. This Improvement has been authorized and is in the process of being designed and constructed at the present time. When the Tri-Municipal Plant expansion is complete, the flow will be able to be delivered from this project into the system. If the approvals of the subdivision are complete prior to the plant expansion, application could be made via the Town Board to the Tri- Municipal Sewer Commission for early entry. This would be addressed when applicable. Joseph E. Paggi, Jr., P.E. Ernst Manln, Jr., P.E., L.S. Charles R. Del Bene, Jr.. P.E. Planning Board RE: Keenan Acres - 2 - December 7, 1999 . During the submission of the subdivision plans, a detailed plan of the proposed collection system, including the two (2) lots on pye Lane, will need to be submitted. When they are submitted a detailed design review will be done. Preliminary review shows that there are numerous sections where the proposed collector lines are too close to the right- of-way lines and do not create a proper separation to other utilities. This will need to be looked at. . The capacity of the existing line on Vorndran Drive will need to be looked at with respect to capacity for the proposed twenty (20) lots that would be tributary to it. This is said because there is a documented history of sewer backups just downstream of the proposed connection. The number of pump stations that are tributary to these lines has at times caused flow problems in the existing collection system. This will need to be studied thoroughly by the Applicant in conjunction with the Town, and an agreeable point of connection to the existing sanitary sewage collection lines arrived at. 5. The location of all existing utilities in the Central Hudson easement will need to be identified and located. 6. With respect to Water SUDDlv: . The Town is in the process of augmenting their source supply that feeds this area. . A detailed submission of the proposed distribution system, including the connection point and service to the two (2) lots in Pye Lane, will need to be developed and submitted during the subdivision process. Of extreme importance is the proposed separation to all of the utilities that will be within the right-af-wav. 7. An overall Stormwater Management Plan and Report will need to be developed. The Town will be looking for qualitative and quantitative mitigation of any new stormwater flows generated by the development of the subdivision. 8. Any New York State Designated Freshwater Wetlands and/or Federal Regulated Wetlands will need to be identified on the map, and any infringement will need to be mitigated. 9. A brief review of the submitted Road Profile indicates that there are vertical curves with insufficient length. This will need to be studied by the Design Engineer. All horizontal curves appear to be appropriate. Planning Board RE: Keenan Acres - 3 - December 7, 1999 10.
