Such recreational vehicle is not used as a permanent dwelling. Leased areas for parking recreational vehicles shall meet requirements for mobile home parks.
RELEASE RATE

Major traffic streets are those serving large volumes of comparatively high-speed and long-distance traffic. Traffic is fed into major streets by collector streets.
Collector streets are those which, in addition to giving access to abutting properties, intercept minor streets or marginal access streets and provide routes, carrying considerable volumes of traffic, to community facilities and to major traffic streets.
Local streets are those used primarily to provide access to abutting property.

SUBSTANTIAL IMPROVEMENTS
Any repair, reconstruction or improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure either before the improvement or repair is started, or, if the structure has been damaged and is being restored, before the damaged occurred. For the purposes of this definition, substantial improvement is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimension of the structure. The term does not, however, include either any project for improvement of a structure to comply with the existing state or local health, sanitary or safety code specification, which are solely necessary to assure safe living conditions, or any alteration to a structure listed on the National Register of Historic Places or the State Inventory of Historic Places.
