Those wishing to use shared parking as a means of satisfying off-street parking requirements must submit a shared parking analysis along with a design review application that clearly demonstrates the feasibility of shared parking. The study must be provided in a form established by the zoning administrator. It must address, at a minimum, the size and type of the proposed development, the composition of tenants, the anticipated rate of parking turnover and the anticipated peak parking and traffic loads for all uses that will be sharing off-street parking spaces.
(4)
Agreement for shared parking. A shared parking plan will be enforced through written agreement among all owners of record. An original executed and acknowledged copy of the agreement between the owners of record must be submitted to the town for recordation in a form approved by the town attorney. Recordation of the agreement must take place before issuance of a building permit for any use to be served by the shared parking area. A shared parking agreement may be revoked only if all required off-street parking spaces will be provided in accordance with the off-street parking schedule. (See section 21-895.)
