12.28.210: SIDEWALKS; REQUIREMENTS FOR CONSTRUCTION AND IMPROVEMENT:
   A.   Sidewalk Construction Required: Hereafter when building structures are constructed on or moved to or alterations are made to existing structures on lots within the city where there are no sidewalks, the persons constructing, or causing such construction, or moving, or causing to be moved such structures, or altering or causing to be altered such existing structures on the lots, shall, during the construction, moving or alteration of structures, construct sidewalks and curb ramps as described in sections 12.28.220 and 12.28.230 of this chapter.
   B.   Subdivision Improvements: Hereinafter, but subject to the provisions of subsection C5 of this section regarding hillside subdivisions, sidewalks and curb ramps will be required to be constructed as subdivision improvements.
   C.   Exceptions To Sidewalk Requirements: No sidewalk is required when:
      1.   The building permit is for an amount less than thirty thousand dollars ($30,000.00), or the value of a structure moved onto the lot together with the amount for which the building permit is issued is less than thirty thousand dollars ($30,000.00); however, if a footing and foundation only building permit is issued, and a subsequent building permit is issued for the structure that is to be placed on top of that same foundation, and the combined valuation of both permits exceeds thirty thousand dollars ($30,000.00), then for the purposes of this section both permits shall be considered as one permit and sidewalks shall be required subject to any exceptions further defined herein.
      2.   There is a natural change of elevation in the ten foot (10') strip adjoining the curb of greater than four feet (4') and a safe alternative pedestrian pathway is available.
      3.   In a previously developed residential neighborhood:
         a.   All of the lots on one side of the street have been previously built upon in accordance with city codes without sidewalks; and
         b.   Said lot frontages without sidewalks extend a maximum of four hundred fifty (450) front feet in either direction or to the nearest intersection, whichever is less; and
         c.   A neighborhood for purposes of all parts of this section shall be defined within the limits delineated in subsections C3a and C3b of this section;
         d.   In the event a local improvement district is created in the neighborhood, this section shall no longer apply.
      4.   The building permit is for a portable classroom which meets the parking requirements of subsections 17.44.050D4 and D5 of this code and other requirements of section 17.44.050 of this code.
      5.   There is a hillside subdivision. A "hillside subdivision" is defined as a subdivision where the highest and lowest points are at least one thousand feet (1,000') distant horizontally and the difference in elevation is at least thirty percent (30%) of the horizontal separation.
      6.   Sidewalks may not be required for immediate installation if the requirements of subsection 12.28.180C, D, or F of this chapter are met. However, such sidewalks will be installed at such time that curbs would be pursuant to subsections 12.28.180C, D, and F of this chapter.
   D.   Sidewalk Length:
      1.   The length of the sidewalk required on large lots shall be limited to one hundred feet (100') or ten percent (10%) of the building permit valuation, whichever is greater. For the purposes of this calculation, the price of the sidewalk shall be determined by the most recent sidewalk bid available to the city. Remainders of twenty percent (20%) or less shall be included in the required sidewalk.
      2.   However, if the length of required sidewalk would exceed five hundred feet (500') and the building permit is for an alteration or modification of an existing structure, the city may enter into an agreement with the property owner to construct the length of sidewalk exceeding five hundred feet (500') within a period of time not to exceed five (5) years.
   E.   Sidewalk Location: Sidewalk location shall allow for a five foot (5') separation between the curb and the sidewalk in residential areas. Sidewalk location shall be adjacent to the curb in commercial areas, except as otherwise allowed by this chapter or title 17 of this code.
   F.   Exceptions:
      1.   In the event of less than adequate right of way, reduction of the parking strip or placement of the sidewalk against the curb shall be allowed, dependent upon the width of the right of way.
      2.   The occurrence of the following natural and manmade features shall allow alternate placement:
         a.   Trees and shrubs larger than six inches (6") at the base;
         b.   A grade change between two feet (2') and four feet (4') in the ten foot (10') strip adjoining the curb;
         c.   The presence of permanent structures.
      3.   When sidewalks are being installed in a local improvement district construction project, the sidewalk may be located next to the curb at the request of a majority of the property owners within such district witnessed by a written petition filed with the city prior to the awarding of the contract for the construction of the sidewalk.
