OF PAGES INCLUDING COVER: 8 PHONE NUMBER: SENDER’S REFERENCE NUMBER: RE: YOUR REFERENCE NUMBER: Crawford – (2) Lot Subdivision Water, Sewer & Basic SWPPP  URGENT  FOR REVIEW  PLEASE COMMENT  PLEASE REPLY  AS REQUESTED ENGINEERING REPORT: INTRODUCTION: Engineering America Co. has been retained by the applicant, Jessica Crawford, to provide land planning and site/civil engineering services in connection with the subdivision application for #16 Excelsior Spring Ave. in the City of Saratoga Springs, Tax Map # 166.10-1-7. Subdivision approval will be required from the Planning Board which includes all requirements listed on the City of Saratoga’s Preliminary/Final Subdivision Approval Required Submittal Checklist. This report is intended to fulfill items 4 & 6 of the Required Items part of the Preliminary / Final Subdivision approval checklist. DESCRIPTION OF INTENDED SITE DEVELOPMENT & USE: The site, #16 Excelsior Spring Ave. is located at the South East intersection of Excelsior Spring Ave. and Audrey Ln. in Saratoga Springs New York. The 32,743 sq.ft. lot has an existing single family residential building with attached garage. The existing dwelling is accessed via paved driveway from Excelsior Spring Ave. The lot area is nearly level in the area of the existing house and across the property. The property is mostly grassy with lawn & garden areas, a few larger mature trees with additional trees along the South property line along Audrey Ln. and at the intersection. 2 The proposed subdivision of this parcel would result in dividing the single lot into two lots. The existing dwelling would be located on a 20,033 sq.ft lot (designated as Lot 1 on the map). The existing driveway access off of Excelsior Spring Ave. would be removed for safety (as requested by the Planning Board). A new driveway for Lot #1 would be constructed for access off of the South property line along Audrey Ln. The existing electrical utility connection overhead from a utility pole along the existing Eastern property line, would be required to be relocated. A zoning variance was granted by the City of Saratoga Zoning Board of Appeals on June 2, 2025 for the existing residence remaining on Lot #1: Min. Rear yard Setback (to existing residence): 30’ required / 12.6’ proposed: 17.4’ variance (58% relief). The new lot to be created to the East of the existing dwelling, would be subdivided from the main parcel and marketed for sale as a residential building lot. The new Lot 2 is proposed to be 12,710 sq.ft. in area. There are no variances proposed for this lot. Compliance with the requirements of Table 3-A of the City of Saratoga Springs Unified Development Ordinance (UDO) for the lots within a UR-1 District is as shown on the subdivision plat pages S2 & S3 WATER REPORT : Currently, there are 2 bedrooms within the existing single-family dwelling on the property (Lot 1). Using a standard demand of 110 gallons per capita day (gpcd) the existing property can be estimated to have an annual water consumption usage of 80,300 gallons. Assuming the new lot will accommodate a single-family residence with 4 total bedrooms the annual water consumption would increase by 160,600 gallons to 240,900 gallons (increase of 440 gallons per day). There is a 6” water main located in Excelsior Spring Ave. The existing residence appears to be currently connected to this main with services to remain unchanged. There is a 6” water main located in Audrey Ln. A new 3/4” Type K copper water service connection is being proposed for the new residence on the proposed new Lot #2. SANITARY REPORT : There are 2 bedrooms within the existing single family residence. Using a standard sanitary sewer of 110 gallons per capita day (gpcd) the existing property can be estimated to have an annual sanitary load of 80,300 gallons. Assuming the new lot will accommodate a single-family dwelling containing 4 bedrooms the annual sanitary load for the two lots will increase by 160,600 gallons to 240,900 gallons. 3 There is an 8” sanitary sewer main located in Excelsior Spring Ave. The existing residence appears to be currently connected to this main with services to remain unchanged. There is a 12” sanitary sewer main located in Audrey Ln. The proposed new single dwelling unit building would be expected to use a 6” diameter SDR-35 service line connecting to this main. The additional load from the construction of the new residence is not expected to tax the capacity of the municipal system. STORMWATER & BASIC SWPPP / EROSION CONTROL SOIL CONDITIONS: The project site (in location of the proposed new lot & current residence) is slightly pitched towards Audrey Ln. Soils on this site appear to be WnB (Windsor B) according to Saratoga County Soil surveys. the depth to any restrictive feature in this soil type is typically greater than 60”. The soil is classified as very deep, excessively drained, rapid permeability, slow surface runoff and slight erosion hazard. SEDIMENT & EROSION CONTROL: A sediment and erosion control plan has been developed in order to specify minimum controls and measures to reduce sediment runoff during construction. - Construction Entrance: One construction entrance has been specified to accommodate the new driveway off of Audrey Ln to the proposed existing residence on the new Lot #2. No construction entrance is required for the proposed new driveway for Lot #1 onto Audrey Ln. - Topsoil: A potential topsoil storage area for grading backfill will be identified (possibly located at the North West corner of the new lot #2) and will be surrounded by silt fencing. In general, excavation is proposed to be limited to the site modifications as relative to removal of the Lot 1 existing driveway, installation of the Lot 1 new driveway and Lot 2 new house construction with driveway. All driveway removal materials shall be removed from the site & not buried. No soil is proposed to be removed from the site. - Concrete Wash: A Concrete washout location has been proposed at the South West corner of the new Lot #2. Concrete washout details and instructions are include on page S-4 of the subdivision development plans. 4 Sediment Control: Less than 0.25 acres are anticipated to be disturbed during construction of the new Lot 2 residence and installation of the new Lot 1 driveway. Silt fencing has been specified around the perimeter of the existing Lot 1 driveway to be removed, as well as surrounding the new Audrey Ln. driveway. In reference to Lot 2, silt fencing has been specified around the perimeter of the site to reduce silt migration off site during construction of any new house.
