If required, alley maintenance or upgrades shall extend across the frontage of the proposed parking spaces to the nearest public right-of-way, as determined by the city engineer. The need for alley maintenance shall be a component of the special land use review for triplexes and fourplexes, and recommendations from the city engineer and fire marshal shall be transmitted to the appeal board of adjustment for their consideration.
Maintenance, upgrades, and/or improvement to a public alley necessitated by a new development shall require a public improvement permit prior to commencing work.
