With the passage of “Phase 2” of the National Pollution Discharge Elimination System (NPDES) in 2003, the focus of stormwater management and control has been broadened in scale to include smaller construction sites. Phase 2 regulations lower the threshold to one or more acres of disturbance, thus, even large individual home sites may be subject to the regulations of NPDES. “Phase 2” regulations require that discharges leaving the construction site meet minimum requirements for both stormwater quantity (peak release rates) and water quality. Preparation of stormwater controls during construction (erosion and sedimentation control) and post construction (water quality and quantity control facilities) are typically required and included in a Storm Water Pollution Prevention Plan (SWPPP).

WEC provides a comprehensive range of services including Erosion & Sedimentation Control Plan preparation, permanent stormwater control design, SWPPP preparation and post construction monitoring and inspection. Our projects have ranged from as small as 2 acres to over 100 acres in size and have included residential, commercial and planned unit developments. All of our projects include coordination with local municipal authorities, resource agencies and presentation of proposed stormwater treatments at public meetings. This experience has allowed us to gain a solid working relationship with review boards and agencies resulting in efficient designs and cost savings to our clients

WEC Stormwater Projects By Type

Representative Projects


East Hills Living Center, Binghamton, NY

East Hills Living Center, Binghamton, NY

This project involved preparation of a SWPPP for the construction of a new adult living complex in Binghamton, NY. The SWPPP was developed in accordance with NPDES and New York Stormwater regulations. The plan included design of a closed storm sewer collection system, a series of interceptor swales and a micropool extended detention pond. The pond was designed to provide both water quality and quantity controls. The plan also included preparation of erosion and sedimentation control plans for a multi-phased development plan.


Mirabito SWPPP, Castle Creek, NY

Mirabito SWPPP, Castle Creek, NY

This project included preparation of a stormwater pollution prevention plan for a convenience store/gas station facility in accordance with NPDES regulations. The plan included the design of two stormwater micro-extended detention ponds and a series of intercepting swales. The plan also included the preparation of erosion and sedimentation control plans.


Broome County Public Safety Building, Binghamton, NY

Broome County Public Safety Building, Binghamton, NY

This project consisted of completion of a SWPPP at the Broome County Public Safety Facility. Work Tasks included design of permanent stormwater management practices and temporary erosion and sedimentation control measures. The project featured extensive use of green-infrastructure design including a large, complex area of porous pavement and retrofit of a dry detention basin into a wetland stormwater pond.


Port Dickinson & Vestal, NY Hydrologic and Hydraulic Analysis

Port Dickinson & Vestal, NY Hydrologic and Hydraulic Analysis

This project included detailed hydrologic and hydraulic modeling of interior protected areas of a USACOE levee and flood control system in the Village of Port Dickinson and the Town of Vestal, NY. During the flood of September 2011, record high stages along the Susquehanna and the Chenango Rivers caused extensive interior flooding behind the levee system due to the existing pumping facilities being overwhelmed. This project included a detailed hydrologic and hydraulic study that analyzed the relationship and timing of localized interior flooding on the protected side of the levees to riverine flooding conditions along the Chenango and Susquehanna Rivers. The study included analysis of flood mitigation alternatives including conceptual sizing of additional stormwater pumping systems.
