Woodard a Curran Engineer's Opinion of Probable Construction Costs (EOPCC) Summary EOPCC Notes: ► Scope and quantities included in this estimate are based on preliminary concepts and aerial takeoffs. ► Construction General Conditions includes general contractor's overhead costs associated with Division 01 specifications including, but not limited to, insurance, bonding, mobilization, etc. ► Item 9 allowance for off-site disposal of excess fill material assumes that the existing material meets NYSDEC restricted residential use criteria. Testing is required to determine soil classification for disposal purposes during construction. ► Assumes general contractor is contracted with Town of Mamaroneck and the project that complies with prevailing wage labor rates. ► Does not include repairs or replacement of existing site utilities. ► Assumes that a final grading plan can accommodate no net filling within the 100-year floodplain and there is no need to provide compensatory storage. ► Differential settlement mitigation allowance is intended to set aside funds for solutions that are to be determined for reducing the potential for and impacts from differential settlement for proposed surfaces (e.g. synthetic turf, asphalt parking area, etc.). ► Assumes proposed stormwater discharge is directly to a tidal waterbody, therefore flow attenuation is not required. ► Does not account for costs associated with a seasonal outdoor ice rink. ► Does not include soft costs associated with design development, permitting, bidding, contractor procurement, design services during construction, resident project representative, etc. Woodard$Curran Q&A Woodard Steven Lauria, PE, Senior Project Manager & Curran Thomas Shay, PE, Senior Technical Manager Woodard &Curran TECHNICAL MEMORANDUM TO: Jaine Elkind Eney, Supervisor, Town of Mamaroneck CC: Robert Wasp, PE, CDT, Town Engineer,Town of Mamaroneck Anthony C. Catalano, PE, BCEE, Senior Principal,Woodard &Curran PREPARED BY: Thomas P. Shay, PE,Technical Manager, Woodard &Curran REVIEWED BY: Steven Lauria, PE, Project Manager,Woodard &Curran DATE: June 13, 2023 RE: Regulatory Permitting Review Associated with the Feasibility Assessment for Town of Mamaroneck Fields Adjacent to Hommocks Middle School We understand that the Town of Mamaroneck is evaluating the redevelopment of the open space area to the rear(east)of the Hommocks Middle School property,south of Hommocks Road,and north of Flint Park. The existing area is currently open lawn and used as athletic fields. The project components under consideration include a multi-sport synthetic turf athletic field, a multi-sport natural grass athletic field, LED athletic field lighting, a shade structure with picnic tables, walkways, and related amenities and supporting utility infrastructure.As part of Woodard &Curran's approved scope for the Feasibility Assessment for Town of Mamaroneck Fields Adjacent to Hommocks Middle School, we have prepared the following preliminary regulatory permitting review. REGULATORY PERMITTING REVIEW Based on review of various public databases, mapping, and our team's experience, the following is a preliminary list of anticipated permits, approvals, and environmental conditions that we expect will be necessary to investigate further and potentially obtain some form of approval for during the design and permitting phase of the project. 1. NYSDEC SPDES Permit for Stormwater Discharges During Construction (Notice of Intent) • Stormwater Quality • Stormwater Flow Attenuation • Stormwater Pollution Prevention Plan (SWPPP); including Erosion &Sediment Controls 2. Work within the 100-year FEMA Floodplain (No filling) 3. State Environmental Quality Review (SEQR) a. Critical Environmental Area (East Creek, Hommocks Conservation Area, Hommocks Salt Marsh Complex, Hampshire Country Club, Long Island Sound) 4. USACE/NYSDEC/NYSDOS Joint Application • Tidal Wetlands (and Adjacent Area/Buffer) • SC Stream Classification (Stream 935-69) • Coastal Consistency(Coastal Area with a Local Waterfront Revitalization Program/Plan) 5. SHPO Archeological Sensitive Area Town of Mamaroneck(0214798.00) 1 Woodard&Curran Eng and Geo Svcs P.A. P.C. Regulatory Permitting Review June 13,2023 Woodard &Curran Based on review of the public database and mapping information, the proposed project/site is not anticipated to include permitting or approvals associated with any of the following criteria: 1. Project site is not located within 2,000 feet of any site in the NYSDEC Environmental Site Remediation Database 2. No unique geologic features 3. Waterbodies are not listed as impaired 4. Not a designated floodway 5. Not a sole source aquifer 6. No significant natural community 7. No state or federal endangered or threatened species 8. No rare plants or animals 9. No agricultural district 10. No registered national natural landmarks 11. Athletic field lighting towers do not exceed FAA OE/AAA Notice Criteria In addition to the formal permitting requirements, it is anticipated that the design will incoporate the following considerations for a more environmentlaly responsible project: 1. Dark-Sky Compliance (athletic and parking lot lighting) 2. Synthetic Turf System Materials • Natural Infill (shock pad required) Please note that extent of the permitting and approvals scope and associated requirements may only be known upon submission of formal jurisdictional request determinations to the respective agencies and once the final scope of design and construction is determined.

Scope and quantities included in this estimate are based on preliminary concepts and aerial takeoffs 2. Construction General Conditions includes general contractor's overhead costs associated with Division 01 specifications including,but not limited to,insurance,bonding,mobilization,etc. 3. Item 9 allowance for off-site disposal of excess fill material assumes that the existing material meets NYSDEC restricted residential use criteria.Testing is required to determine soil classification for disposal purposes during construction. 4. Assumes general contractor is contracted with Town of Mamaroneck and the project that complies with prevailing wage labor rates. 5. Does not include repairs or replacement of existing site utilities. Page 1 of 2 6. Assumes that a final grading plan can accommodate no net filling within the 100-year flood plain and there is no need to provide compensatory storage. 7. Differential settlement mitigation allowance is intended to set aside funds for solutions that are to be determined for reducing the potential for and impacts from differential settlement for proposed surfaces(e.g.synthetic turf,asphalt parking area,etc.). 8. Assumes proposed stormwater discharge is directly to a tidal waterbody,therefore flow attenuation is not required. 9. Does not account for costs associated with a seasonal outdoor ice rink. 10. Does not include soft costs associated with design development,permitting,bidding,contractor procurement,design services during construction,resident project representative,etc. *This cost opinion is preliminary and is intended as a guide to help with initial project budgeting and fund allocation. Estimates can be revised as design progress is made in order to develop more accurate project cost projections. Page 2 of 2 Phone WHITE PLAINS, N.Y.
