Any structure hereafter erected or altered shall comply with the height limitations of the district in which it is located except as specified below.

The height limitations of this appendix shall not apply to church spires, belfries, flag poles, monuments, cupolas, domes, ornamental towers, nor to observation towers not intended for human occupancy, water towers, transmission towers, radio or television towers or aerials. These exclusions shall not apply in the vicinity of airports.

The setback requirements of this appendix shall not prohibit any necessary retaining wall nor prohibit any wall or fence, except that in a residential district, no wall or fence shall exceed eight feet in height within a side yard or rear yard and shall not extend into a required front yard. Further, no wall or fence shall extend into a required land use or landscaping buffer without specific authorization by the zoning administrator or city council.

Any building, structure or use thereafter erected, altered or established shall comply with the yard space requirements of the district in which it is located except as specified herein. The required yard space for any building, structure or use and such required yard space shall fall entirely upon land in a district or districts in which the principal use is permitted.

The front yard requirements of this appendix shall not apply on any lot where the average depth of the front yards of existing buildings on adjoining lots located wholly or in part within 300 feet on each side of such lot within the same block and zoning district and fronting on the same side of the street is either greater or less than the minimum required front yard depth.

A temporary building for use in connection with a construction project or land subdivision development shall be permitted on the land of the project during the construction period. Temporary buildings related to a subdivision development shall be removed when 60 percent of all lots are occupied by completed homes or within four years, whichever occurs first.

Except in districts allowing the construction of buildings or structures to the property line, there shall be provided an unobstructed view across the triangle formed by joining points measured 20 feet distant along the property line from the intersection of two streets or 15 feet along both the street and alley line from the intersection of a street and an alley. Within said triangle there shall be no sight-obscuring wall, fence or foliage higher than 30 inches above grade or, in the case of trees, foliage lower than eight feet. Vertical measurement shall be made at the top of the curb on the street or alley adjacent to the nearest side of the triangle, or if no curb exists, from the edge of the nearest traveled way.

Heights of fences, hedges and other continuous foliage shall be measured from the adjacent top of the street curb, surface of an alley or the officially established grade thereof, whichever is the higher. On inside lot lines, the measurement shall be from the average grade of the lot line of the parcel or property having the lower elevation.

The zoning administrator may approve, or may direct as a condition for granting site plan or landscaping plan approval, that fences or plantings of a height in excess of these regulations be placed as shielding between different uses or incompatible types of development of like or similar uses, provided that no such approval shall have the effect of reducing corner visibility as, provided for herein. This requirement shall be subject to approval by the affected parties.

Every building hereafter erected or moved shall be on a lot adjacent to a public street, and all structures shall be so located on lots as to provide safe and convenient access for servicing, fire protection and required off-street parking.

Vehicles, trailers or equipment used recurrently for commercial or industrial purposes and weighing in excess of 3,600 pounds or containing a weight load capacity in excess of 3,000 pounds shall not be parked or stored on or about any property within a residential zoned district. This section shall not apply to construction vehicles, trailers or equipment temporarily located within a subdivision, provided such vehicles, trailers or equipment are used in connection with dwelling units under construction within said subdivision.

Except as heretofore provided, all vehicles, trailers and equipment which do not exceed the stated weight limitations may be parked or stored only in the side yard or the rear yard or in an enclosed building. In the case of a corner lot, no such vehicle, trailer or equipment may be parked or stored in the side yard on the street side of the lot. Recreational vehicles or equipment may be parked or stored only in the side yard or the rear yard or in an enclosed building. No such recreational vehicle or equipment shall be used for living, sleeping or housekeeping purposes when parked or stored on a residential lot, or in any location not approved for such use. This section does not apply to properly licensed operable vehicles not used recurrently for commercial or industrial purposes.

Vehicles and trailers of any kind without current license plates, or vehicles, trailers or equipment permitted to remain in an inoperable condition for more than 30 days shall not be parked or stored on or about any property within a residential zoned district. Provided, however, this provision shall not apply to vehicles, trailers or equipment stored in an enclosed structure or appropriately covered and located in the rear yard area.

Automotive vehicles having more than four wheels, major recreational equipment and school and other buses are prohibited from parking on residential streets or within public rights-of-way.

Public rights-of-way especially for city, county or state roads are permitted in all zoning districts.
