The Redding Ridge fire station can be overhauled. The Redding Zoning Commission has signed off on the fire district's plans, as long as the Building Department also gives approval. The existing structure on Blackrock Turnpike would be demolished, the parcel would be expanded a new building for the volunteer firefighters could be constructed.  Construction would be done in four phases, over several years.  Overall work also calls for parking lot expansion and septic system installation.  The architect’s plan involves building a retaining wall to filter stormwater into the wetlands.  Plans are being drawn up for the building department so a construction estimate can be obtained.  The cost is expected to be around $4 million.  Taxpayers in the fire district will eventually vote on funding for the project.  During the work firefighters would operate out of the center firehouse and a member would store one of the engines in their heated barn.
