I. NARRATIVE SUMMARY
A. Background
The proposed Cortlandt Pitch Project is located in the Town of Cortlandt, NY and
owned by New York Indoor Sports, Inc. The property is located along U.S. Route
202/ Crompond Road, set back at least 260-feet north through NYSDOT-owned land,
between the intersections of Rte. 202 and the Bear Mountain State Parkway to the west
and Maple Row to the east. The site is bounded by adjacent Bowling Alley driveway
(Lincoln Avenue) and parking lot to the east, Lincoln Titus Elementary School and
outdoor playing field to the north, and residential area to the west.
The property was previously owned as farmland and is currently largely meadow and
open space, except for a single family residence and two accessory buildings on-site. The
main house was originally located in the Right-of-Way and was relocated when the land
was taken by the State for a potential future parkway extension. The R.O.W. land is
currently undeveloped except for separate driveways to the on-site home and adjacent
Bowling Alley, with meadow and limited wooded areas along the roadways. The
majority of the site gradually slopes from south to north, with a portion separated by a
ridge that drains west to east to an existing off-site un-named watercourse. See Existing
Conditions Figure EC-1.
B. Project Description
The subject property is situated on a +/- 6.3 acre parcel with a current use of a
occupied single-family dwelling and supported by an accessory buildings, public water
supply and an onsite individual subsurface sewer treatment system. All existing
structures and utilities will be razed and removed from the site. The existing subsurface
septic tanks and/or infiltration pits will be demolished in place and backfilled in
accordance with the Westchester County Department of Health (WCDOH) rules and
regulations. The water supply will be removed and abandoned in accordance with the
Town of Cortlandt requirements. The proposed 56,680 square feet building foot print
for an indoor sports facility that will include soccer/multi use fields with attached
exercise rooms, offices, restrooms and eating facilities.
C. Septic Area Soils
Reported from the United States Department of Agriculture (USDA) Natural
Resources Conservation Service (NRCS), the soils within the septic area is Paxton
(PnB) fine sandy loam, 3-8 percent slopes. See Figure No. 1 Soil Map.

D. Wetlands
Within the 6.3-acre project site, there is a 0.28-ac wetland delineated by the wetland
scientist, The Town’s consultant indicates the wetland was previously disturbed and
isolated, resulting in limited importance for wildlife habitat. The wetland is not federally
regulated.
E. Project Permits and Approvals
The following are anticipated permits and approvals to be sought for the Project.
Town of Cortlandt
• Site Plan Approval
• Wetland Permit
• Watercourse Diversion
Westchester County (WC)
• Department of Health: Onsite Wastewater Treatment System, Backflow Devices
State of New York (NYS)
• Department of Environmental Conservation: SPDES Permit
• Historic Preservation Office: Historic and Archeology Sensitivity Review
• Department of Transportation: Highway Work Permit
Federal (US)
• Army Corps of Engineers: Wetland Permit (off site wetlands)
II. Construction Program
A. Duration of Activity
The construction activity is expected to be completed over approximately a one-year
period and will involve the grading and construction of new access roadways,
parking areas, underground utility systems, building footing and foundation systems,
building structures, stormwater management measures, subsurface septic system,
landscaping and other physical improvements.
B. Sequencing Schedule
The majority of the proposed project will be constructed in one phase. Which will
incorporate the clearing and demolition of existing buildings and construction of the
new facility, subsurface septic and utilities and driveway improvements.
5
C. Construction Refuse Control All contractors working on the site will provide adequate trash containment services for the construction site at the start of work to maintain a clean, debris-free work area. Typical facilities may be covered containers with openings three inches or smaller or approved equal, and will be emptied on a regular basis. Refuse will be removed from site via a solid-waste contractor and be recycled or disposed per Federal, State and local requirements. Refuse will not be disposed of on site.
III. SUBSURFACE SEWER DESIGN
A. Engineering Criteria and Testing The design was completed to comply with the New York State Design Standards for Intermediate Sized Wastewater Treatment Systems March 5, 2014. The design includes the following. Five deep test holes were performed within the proposed subsurface sewer treatment area which the soil consists mostly of a sandy loam with water seep between 62 and 72 inches and one test hole mottled soils was observed at approximately 42 inches. Eight percolation tests were performed between depths 48 and 66 inches from existing grade. A soil percolation rate of 16-20 min./inch or 0.7 GPD/ft2 is used for the design of required absorption area. See Appendix for testing data sheets.
B. Design Flow and System Type
The average daily design flow was estimated to be 2,588 gallons per day. Excavated test pits indicated groundwater seep between five and six feet and mottled soils at 42 inches which were measured from finished grade. To provide the required separation from ground water the design includes placing a minimum of 36 inches of run-of-bank sand and gravel fill over the entire primary and expansion areas. The subsurface treatment systems primary absorption area will be located within a lawn area and the 100 percent reserve area will be located in a paved parking area. The system layout meets the required separation distances listed in Table 2 of the Design Manual. See Appendix for Table B-2.
C. Tanks and Pump Station Prior to the subsurface treatment system pretreatment tanks will include a 4,000 (1.5 x average daily flow) gallon septic tank and a Type II 2,000 gallon grease interceptor for the kitchen service area. A pump station will be required for the difference in elevation of the septic tank outlet pipe and absorption fields, this will also allow to dose the system to provide a system resting period.
6
D. Subsurface Treatment Area
The projected daily sanitary load for the proposed development site is calculated to be 2,588 gallons per day (gpd), see Table 1 for detailed sanitary loading calculations. An 8-ft x 4-ft x 2.2-ft Tri-Galley subsurface infiltration system was chosen for the subsurface sewer treatment. The Tri-Galley provides a 5.2ft2 of effective infiltration per linear foot plus 15.5 ft2 for each end section. See Figure No. 2 for Tri-Galley Detail. Using an application rate of 0.7 GPD/ft2 and a sanitary load of 2,588 GPD, the disposal system will require 3,697 ft2 of Tri-Gallies.
E. Flooding The proposed sewer treatment system is not located within the 100-year floodplain, and therefore, should not be impacted by flooding.

For retail or commercial establishments, give total number of employeesand/or customers per day. For summer camps, resorts, etc., give total number of residents.
DISCHARGE DATA For discharges to surface waters, each separate outfall pipe shall be assigned an outfall number. Surfacewater discharges are outfalls to streams, lakes, ponds, ditches, oceans, etc. Subsurface disposal systemsare discharges to groundwater from such facilities as seepage pits, seepage lagoons, tile fields, etc. Designflow is the average gallons per day of wastes that the disposal system is designed to handle. Examples oftypes of wastes are: sanitary (e.g. toilet, lavatory, showers, etc.), cooling, kitchen wastes (restaurants),laundry wastes (laundromats), filter backwash, etc. Examples of type of treatment are: septic tank-tile fields(or seepage pits), activated sludge, biodiscs, sand filtration, etc. Name of water should be given fordischarges to surface water if water body has a name, or designated as a tributary or subtributary of thenearest downstream named body of water. Class (official classification) and waters index number arepublished in the Official Compilation of Codes, Rules and Regulations of the State of New York, Title6-Conservation, Volumes B. C, D, E, F. The name of and distance to the nearest surface water shall begiven for subsurface disposal systems as well as the soil type (sand, gravel, etc.) and depth to the watertable below the ground surface. If this application is for a facility or subdivision which will have a number ofsimilar disposal systems to handle the same type of wastes (for example, a 40 lot residential subdivisionwhich will have an individual septic tank and leach field system on each lot), then the Discharge Data portionof this application should be completed using the following example as a guide.
