The proposed project consists of a 3 story, 71 unit apartment building with a footprint of approximately 25,555 sf. Additionally, there will be a 3,000sf office/amenity building along the frontage of the parcel to serve the apartments. Associated parking lots, utilities, and landscaping are proposed to serve the development. The project is proposed to be serviced by public utilities via the City of Saratoga Springs DPW. The proposed project area is approximately +/- 3.63 acres, of which +/- 2.91 will be disturbed. This letter/report will describe the water use and wastewater generation for the proposed development. Public water services and sanitary sewer services are proposed to be provided by the City of Saratoga Springs Department of Public Works. WASTEWATER DEMANDS The wastewater generated by the proposed development has been calculated for each residential dwelling. The total wastewater demands have been calculated based on the 10 State Standards of 100 gallons per capita per day (gpcpd) with an estimated population density of 2.0 residents per dwelling unit. The wastewater demands for the amenity building were calculated using the 10 State Standards Hydraulic loading rate of 0.10 sf per square foot of commercial floor space. The Average Daily Wastewater Flow and Peak Hour Wastewater Flow generated for the proposed development are 14,440 gpd and 42.12 gpm, respectively. A detailed outline of the wastewater flow calculations are as follows: Finley Street Residential – Development consist of 71 apartment units and a 3,000 sf amenity building. Apartment building: Population = (71 units) x (2.0 residents/dwelling) = 142 persons Design Average Daily Wastewater Flow = (142) x 100 gpcpd = 3,200 gpd Amenity building : Commercial floor area = (3,000 sf) Design Average Daily Wastewater Flow = (3,000 sf) x 0.10 gallons/sf = 300 gallons pg. 2 Total Design Average Daily Wastewater Flow = 14,440 gpd Total Population = 142 persons Peak Hour Factor (P=population in thousands) = (18 + P1/2) = (18 + 0.1421/2) = 4.20 (4 + P1/2) (4 + 0.1421/2) PHF = 4.20 Cumulative Peak Hour Wastewater Flow = (Average Daily Wastewater Flow) x (Peak Hour Factor) = (14,440 gpd) x (4.20) = 60,648 gpd = 42.12 gpm (calculated design flow, required flow) The proposed apartment and amenity buildings will have privately owned e-one grinder pumps that will discharge sanitary sewer via a 2” DR11 low pressure forcemain. The proposed forcemain will connect to a new forcemain manhole at Finley street and will then travel east connecting to the existing gravity sewer manhole at the intersection of Adelphi Street and Union Street. Based on the properties of a 2” HDPE DR-11 forcemain pipe and a 2 fps cleansing velocity, the capacity of the proposed 2” piping is 19.58 gpm minimum and 58.75 gpm maximum. Based on the calculated 42.12- gpm flow rate the proposed 2” low-pressure forcemain piping includes sufficient capacity to service the proposed development. WATER DEMANDS The water demand for the proposed development has been calculated for the apartment units and amenity building. The total water demand has been calculated based on the 10 State Standards of 100 gallons per capita per day (gpcpd) with an estimated population density of 2.0 residents per dwelling unit. The water demands for the amenity building were calculated using the 10 State Standards Hydraulic loading rate of 0.10 sf per square foot of commercial floor space. The Average Daily water demand and Peak Hour water demand generated for the proposed development are 14,500 gpd and 45.3 gpm, respectively. A detailed outline of the water demand calculations are included within Appendix A of this report. The project proposes a water main extension from the 6” existing gate valve on Finley Street. The proposed 6” DIP main will be extended approximately 265 linear feet to the west where it will dead end with a gate valve and 6” stub with and end cap for future development. Each building will be serviced by a 6” DIP water service, a new hydrant is proposed within the project area. The City of Saratoga Springs DPW has indicated the existing water supply system includes sufficient capacity to service the proposed development. A hydrant flow test will be conducted in the Spring to confirm. The estimated water usage and wastewater flows for the Finley Street Residential Development are relatively insignificant in comparison with the water and wastewater capacity in the area. Therefore, it is pg. 3 expected that the connection of the water and sanitary systems will not have an adverse impact on the existing utilities. Please review this letter/report and pending your approval please provide an approval letter for this connection. Please contact me at 899-5243 ext. 113 if you have any questions or require any additional information. Thank you. Sincerely, Andrew J.
