Spring Hill Farms

Old Westbury, NY

Show Project Details

To prepare the distinctive Gold Coast Estate character of the 150-acre Phipps Estate, Spring Hill Farms was planned and engineered as an Estate Conservation Subdivision consisting of 22 estate lots with lot sizes ranging from 4-10 acres. Preservation efforts included maintaining the Gatehouse, Greenhouses and ornamental entrance gates. The development entrance area includes a six-acre lake and boathouse within 12-acres of open space. The subdivision roads were built with stone gutters in keeping with the original Gold Coast Estates.

Stone Hill at Muttontown

To preserve the distinctive Gold Coast Estate character of the 148.5 acre Kirby Hill Estate, Stone Hill at Muttontown was planned and engineered as a Conservation Subdivision consisting of 80 parcels including the existing estate manor retained on 7.3 acres.

A clubhouse with recreational amenities and equestrian trails are integrated within the development. The Conservation Subdivision Plan preserved greater than 50 acres of existing forested land, steeply sloped terrain, vernal pools (freshwater wetlands), orchard area, specimen trees, and open field areas. The subdivision layout and infrastructure engineering was guided by the conservation principles of “maximizing open space and minimizing development disturbance.”

This project received the 2009 ACEC New York Silver Award for Engineering Excellence.

Two Master Plan Concepts, Wastewater and Facility Plan, were prepared for the redevelopment of a 326-acre parcel spanning two Towns. One Master Plan Concept was prepared under the Planned Development District zoning and incorporated housing, industrial, retail and recreational elements. The Wastewater Facility Plan included comprehensive analysis for sewering the entire 326-acre site. Analysis of using vacuum assisted technology to reduce capital and operating costs. Engineering Report for sewage treatment plant identified modular approach for constructing a Sequence Batch Reader (SBR) facility with groundwater recharge of effluent.

Approved Design Standards (ADS) were prepared for use in negotiating leases with future occupants. The ADS cover all areas of lot development including site plan approval, approved uses, landscaping, refuse collection, signage, lighting, parking requirements, sewer use regulations, placement of utilities and HVAC equipment, and common area usage.

A Traffic Impact Study and Planned Development District Pre-Application were prepared for the proposed rezoning of the 326-acre Flowerfield site from Industrial to a mixed-use. Six Conceptual Development Plans were studied, as well as four as-of-right scenarios. The development alternates balanced entering and exiting peak hour volumes to minimize site traffic impacts. A new internal road system was proposed to accommodate internal site traffic and, at the same time, discourage “short-cutting” through the site using “smart growth” and traffic calming techniques. A unique methodology was used in the Traffic Impact Study – peak hour site traffic volumes were based on the future capacity of the adjacent road network after potential traffic improvements were assessed. Later on, our office prepared another Traffic Impact Study for the development of a golf course community and championship 18-hole golf course, while maintaining existing industrial and commercial uses. Both plans incorporated smart growth concepts to minimize environmental impacts and maximize a sense of community. The environmental impacts of both plans were analyzed. Our office recently completed a new Traffic Impact Study to compare As of Right scenarios to proposed Change of Zone scenarios for various sections of the overall site. The scope included thirteen (13) study intersections with traffic data collection, Synchro traffic impact analysis with SimTraffic simulations, and a traffic signal warrant study.

Redevelopment of an industrial site into a 349-unit, three-story apartment complex with two interior courtyards, swimming pool, 524 below grade and at-grade parking spaces, and associated site improvements on a 7.1-acre site in the Village of Rockville Centre. The civil design, site plan drawings, Draft and Final Environmental Impact Statement and Traffic Study were prepared. The Application for Site Plan Approval was processed through the Village of Rockville Centre and assistance was provided to the architect with the Design Review Board process. Due to the shallow depth to groundwater an innovative stormwater management design was required in order to retain site runoff on site. A Village utility easement for sewer, stormwater and electrical services was located in the middle of the site and had to be relocated to the property boundary. Infrastructure capacity was analyzed by installing flow meters in the Village’s sewer mains. The mechanical, electrical and plumbing systems were designed for the complex. Each unit has a self-contained natural gas fired HVAC system with domestic hot water and separately meted electrical service. A complete fire protection sprinkler system and ADA compliant fire alarm system was provided.

Metro 303 – Mill Creek Residential Luxury Apartments

West Hempstead, NY

Show Project Details

This project involved the re-development of a key underutilized 1.8 acre parcel at main entry area to the Village. The residential development consists of 172 apartment units in four stories constructed over two below-grade parking levels. The new building includes two outdoor central courtyard spaces including a swimming pool, fountain, terraces, outdoor fireplace, seating areas and gardens. The site improvements also included the entire property streetscape frontage.
