Commercial Stormwater Management for Old Lyme, CT Properties

Old Lyme presents one of the most complex commercial stormwater management regulatory environments on the Connecticut Shoreline, and that complexity is a direct product of the town's geography. Situated at the confluence of the Connecticut River and Long Island Sound, Old Lyme's commercial development sits within a watershed system that flows to some of the most ecologically sensitive and legally protected receiving waters in New England. That ecological sensitivity is reflected directly in the stormwater management standards that apply to commercial development here.

Commercial properties in Old Lyme are subject to Connecticut DEEP stormwater requirements under the General Permit for Stormwater Discharge from Construction Activities and the General Permit for Stormwater Discharge Associated with Industrial Activity, depending on the nature of the commercial use and the extent of the disturbance involved. For commercial projects that require Old Lyme Inland Wetlands Commission review because they involve regulated activities in or near the town's estimated 2,000 acres of inland wetlands or its tidal wetland corridors along the Lieutenant River, Black Hall River, and Connecticut River estuary, stormwater quality management requirements apply in addition to peak discharge reduction requirements. The stormwater quality standards applicable to commercial discharge near Old Lyme's estuarine and tidal resources go beyond the minimum Connecticut DEEP general permit thresholds and reflect the sensitivity of the Connecticut River Estuary and the Long Island Sound watershed to nutrient loading and sediment discharge.

The Halls Road commercial corridor, the Exit 70 and 71 light industrial zone on Hatchetts Hill Road and Vista Drive, the Route 156 coastal commercial zone, and the marina properties along the Connecticut River and tidal waterways each present different stormwater management challenges and different applicable regulatory requirements. We design stormwater management systems for Old Lyme commercial properties that address the specific conditions and applicable requirements of each site's commercial zone.

Every exterior stormwater management system we install is designed for Old Lyme's specific regulatory and hydrological context. We do not work inside buildings and we do not connect stormwater systems to sanitary infrastructure or interior building systems.


Commercial Stormwater Management Services We Provide in Old Lyme

Post-Construction Stormwater Management System Design and Installation

For Old Lyme commercial development and redevelopment projects that require post-construction stormwater management measures under Connecticut DEEP permit conditions or local approval conditions, we design and install exterior systems that meet the applicable performance standards. This includes retention and detention basin systems, bioretention cells, infiltration practices, and the supporting pipe and inlet infrastructure that routes stormwater to the designed management system.

Stormwater Infrastructure Maintenance

Stormwater management systems on Old Lyme commercial sites require ongoing maintenance to perform at their permitted capacity. Catch basins accumulate sediment, detention basin outlet structures can become blocked, and vegetated bioretention areas require periodic attention to maintain their designed infiltration rates. We provide maintenance programs for Old Lyme commercial stormwater systems on schedules appropriate for each system type and the site's specific debris loading conditions.

Catch Basin and Inlet System Upgrades

Existing catch basin and inlet systems on Old Lyme commercial sites may be undersized, incorrectly positioned, or deteriorated to the point where they no longer perform at the capacity the site drainage requires. We assess existing stormwater inlet infrastructure on Old Lyme commercial properties and recommend replacement, upsizing, or supplemental installation where needed.

Site Drainage Grading and Swale Design

Commercial site grading and swale construction that routes stormwater to designed management infrastructure is an integrated component of stormwater management system design on Old Lyme commercial sites. We design and install site grading and swale systems that route runoff from commercial impervious surfaces to catch basins, retention areas, and other designed stormwater management facilities efficiently and in compliance with applicable permit requirements.


The Regulatory Context for Commercial Stormwater in Old Lyme

Commercial stormwater management in Old Lyme involves coordination with several regulatory bodies depending on the scope and location of the project. Connecticut DEEP administers the General Permit programs that govern construction and post-construction stormwater management for commercial development statewide. The Old Lyme Inland Wetlands Commission reviews and conditions commercial development proposals that involve regulated activities near wetlands and watercourses. The Old Lyme Planning and Zoning Commission reviews site plans for commercial development and may impose stormwater management conditions as part of site plan approval. The Old Lyme Historic District Commission has jurisdiction over exterior work in the Lyme Street Historic District, which applies to commercial projects in the Boston Post Road corridor adjacent to that district.

We work with Old Lyme commercial property owners and developers to understand which regulatory bodies have jurisdiction over their specific project and design stormwater management systems that meet the conditions those reviews produce.
