About this file
This is a Permit Planting Plan document prepared by BL Companies, Inc. for the Connecticut Department of Transportation, detailing environmental restoration requirements for the replacement of Bridge No. 02599 spanning Route 101 over Alvia Chase Reservoir in Killingly, Connecticut. The project encompasses three permit planting sheets (PMT-01, PMT-02, and PMT-03) that specify planting locations, species requirements, and habitat protection measures. The permit planting plan designates a total planting area of 1,500 square feet with 90 total plants to be installed, including species such as marsh fern, blue flag iris, narrowleaf cattail, common rush, swamp milkweed, and sweet pepperbrush distributed across wetland zones classified by wetland indicator status (OBL, FACW, and FAC). The document also identifies odonate habitat impact areas with permanent impacts of 0.024 acres and temporary impacts of 0.003 acres, totaling 0.027 acres, along with conservation seeding requirements for disturbed areas both above and below the wetland limit.
All plant material must conform to American Standards for Nursery Stock and be nursery grade straight species with no cultivar substitutions without coordination with the Connecticut Department of Transportation's Office of Environmental Planning (OEP). Proposed plantings require field location approval by CTDOT OEP or their designated representative prior to installation. The plan includes provisions for treatment and removal of invasive vegetation, restoration of disturbed areas, implementation of sedimentation control systems, and protection protocols to avoid disturbance to native vegetation to the maximum extent possible. Water surface elevations were measured on March 17, 2023, at elevation 567.5, and the project site is subject to easements in favor of AT&T for telephone lines and Eversource Energy for electric distribution lines.
