A screengrab from the Norwalk Sailing School website. NORWALK, Conn. — Many people question what will happen at the Calf Pasture Beach Norwalk Sailing School site, now that Bruce Caslowitz isn’t putting in a bid to continue the service he’s offered there for 36 years. The City has issued a request for proposals rather than renew the $1 a year lease to Caslowitz’ nonprofit for another 5-year term, calling for qualified vendors to “provide a sailing instruction program and a seasonal non-motorized watercraft program, at Calf Pasture Beach, during regular park hours.” Among its requirements is a 20% fee based on the previous month’s gross revenue or “a standard monthly rate” to be paid to the City for use of the property.
