(A) Adequate Access: No building shall be constructed or erected on a lot in a zoning district unless adequate access to a fifty foot (50') wide minimum standard all weather public trafficway is provided. Said access may be a private drive providing such drive conforms with the following chart:
PRIVATE DRIVEWAY LENGTH
Width |
100 Feet
|
150 Feet
|
200 Feet |
250 Feet
|
300 Feet
|
20 feet | 8 units | 7 units | 6 units | n/a | n/a |
25 feet | 10 units | 10 units | 8 units | 8 units | n/a |
30 feet | 12 units | 12 units | 12 units | 12 units | 12 units |
This requirement may be limited to a minimum length of fifty feet (50') for driveways serving not more than three (3) single-family residences within the AG and SUI zoning districts.
In commercial and manufacturing zoning districts, a private drive may not exceed three hundred feet (300') in length, must have a developed width of twenty feet (20') for one-way traffic and twenty five feet (25') for two- way traffic and may not serve a total building area of over fifty thousand (50,000) square feet.
The city council may approve additional driveway length in excess of three hundred feet (300') in cases where isolated parcels of land cannot be developed with a minimum fifty foot (50') dedicated right of way.
Such a private drive shall be surfaced with Portland concrete or asphaltic concrete. No zoning subdistrict will be allowed that does not have direct access to a fifty foot (50') wide minimum standard all weather paved public trafficway. (Ord. 2850, 2-21-2006)
(B) Curb, Gutter And Sidewalk:
1. New curb, gutter and sidewalk shall be constructed at the expense of the property owner with and at the same time as all new construction or modification of existing buildings in accordance with city standards on all streets, within and adjacent to the development, and in all zoning districts except the AG district, for all land uses except under any one or more of the following conditions:
a. Sidewalks are not required in the SUI, M1 or M2 zoning districts except on arterial streets or areas of high pedestrian traffic. (Ord. 2347, 9-3-1991; amd. Ord. 2796, 6-14-2004)
2. The city engineer may defer the construction of required curb, gutter and/or sidewalk until other curb, gutter and/or sidewalk is constructed adjacent to other lands in the neighborhood under any one or more of the following conditions:
a. If the total length of existing curb-gutter on both sides of the street in an existing development plus the length of the property in question is less than forty percent (40%) of the total property length adjacent to a standard block unless the curb-gutter will connect to an existing curb-gutter section. The standard block shall be the distance between two (2) intersecting streets or four hundred feet (400') whichever is less. The same criteria shall apply separately to sidewalks. All curb-gutters to be considered as existing shall be to acceptable line and grade.
b. If another governmental agency having jurisdiction over a particular street requests that curb-gutter be deferred.
c. If existing curb, gutter and/or sidewalk is in good repair and to an acceptable line and grade which conforms to the line and grade of other curb, gutter and/or sidewalk in the standard block, it may be retained.
3. Curb, gutter and sidewalk shall not be required or allowed to be constructed or may be deferred if, in the opinion of the city engineer, the improvement would create a traffic hazard or an unusual drainage problem.
(C) Construction Standards For Vertical And Rolled Curb: Both vertical and rolled curb shall be allowed in the city, in accordance with the provisions of this code and in conformance with the standard construction design and specifications for the same, as are on file in the city engineer's office. The most recent construction design and specifications shall prevail.
Standard detail C-2 (4 inch rolled curb) shall be used only when the following applicable conditions have been met:
1. On local residential streets in new developments, when the top of curb to top of curb street drainage capacity is not exceeded by the peak flow generated during a 50-year 24-hour storm. It shall be the developer's engineering consultant's responsibility to compile and submit drainage calculations to the city for review and approval.
2. On residential cul-de-sac streets in new developments which meet the drainage requirements set forth in subsection (C)1 of this section.
3. On local residential streets in existing developments where no curb or gutter exists in the block under consideration and a study by the city engineering department indicates that the proposed installation will meet the drainage requirements set forth in subsection (C)1 of this section.
4. In all cases four inches (4") rolled curb shall be transitioned into six inch (6") vertical curb around all curb returns.
(D) Restrictive Requirements: In areas where two (2) or more zoning districts or subdistricts abut, and said zoning districts or subdistricts have different public improvement requirements, the council may impose the least restrictive requirements if the council finds that imposition of the least restrictive requirements will further the policies and purposes described in chapter 1 of this title.
