Cameron-Cole worked closely with a municipality to evaluate the siting and relevant permitting requirements for a showcase neighborhood enrichment and stormwater improvement project located in a historic preservation neighborhood. The regional stormwater pond and park were designed to capture and treat runoff from approximately 40 acres in a downtown urban area that previously discharged untreated stormwater directly to a local bay.  Utilizing funding from the National Fish and Wildlife Foundation and the municipality’s Stormwater Capital Projects Fund, the pond utilizes a three-tiered advanced treatment system that incorporates proprietary underground pretreatment units to remove debris and floatables prior to entering the wet detention pond. Portions of the proposed pond site were located within the footprint of a groundwater plume associated with a nearby Brownfield site that was undergoing active remediation.  Working closely with the municipality and the state regulatory agency, Cameron-Cole evaluated the mass of contaminants present in a groundwater plume associated with the Brownfield site to determine the feasibility of the proposed development. Adjustments to the static pool volume of the pond were subsequently incorporated into the final design and Cameron-Cole completed treatment of a “hot spot” located near the pond using In Situ Chemical Oxidation (ISCO). Cameron-Cole then designed, installed, and operated a high-capacity treatment system for groundwater recovered during dewatering that was necessary for the construction of the pond.  Upon receipt of regulatory approval of the treatment system, and procurement of the required National Pollutant Discharge Elimination System (NPDES) Permit, Cameron-Cole installed and operated the treatment system for approximately three months during the construction of the stormwater.  During that period, more than 40 million gallons of recovered groundwater were successfully treated to within low Parts Per Trillion (PPT) discharge criteria with no permit excursions. The pond now discharges directly into a coastal mitigation wetland that also contributes to the long-term sustainability of the coastal wetland and adjoining bay. In addition to its significant water quality improvement, the pond and its lush landscape now serve as a habitat for a wide variety of native flora and fauna.
