Engineering AgreementEngineering Agreement:
Download the engineering agreement and work plan approved by CT DEEP for a 55% Clean Water Fund Planning Grant. The purpose is to develop the sewer system designs for the Candlewood Peninsula and Dean Road areas at a greater cost-share by the state than the conventional 20% Clean Water Fund construction grant—a savings to Brookfield of over $500,000. The 45% difference will be provided in the form of a loan from the WPCA to be repaid when the project is funded by a Bond.

Candlewood Peninsula Boring Report
Quoting:
The data suggests that rock and dewatering, while in localized areas will be required, should not have a significant impact on project costs to cause adding additional allowances as part of the project budget cost estimates.

FirstLight Shoreline Management Plan (SMP)
This plan was approved August 2019 by the
Federal Energy Regulatory Commission (FREC)
The plan is designed to promote the protection, preservation and improvement of environmental values into the future mostly through land management. Section VII. a) reads “FirstLight does not have … jurisdiction over public health and water quality. Therefore, the CTDPH, local health departments, CT DEEP and any other jurisdictional bodies are primarily responsible for public health and water quality … on and in [Candlewood Lake].
