(A) No new development or construction that requires a permit under the International Building Code, as adopted by ordinance, shall be allowed on any lot unless it has legal access. All development shall include a minimum of 50% of the necessary additional right-of-way to conform to the required width, as defined in this chapter, if property is adjacent to the road right-of-way or road easement.
(B) All development shall include a minimum of 50% of the necessary additional right-of-way to conform to the required width, as defined in this chapter, if property is adjacent to the road right-of- way or road easement.
(C) Development connecting to or adjacent to a county arterial or collector shall provide adequate acceleration/deceleration lanes using standard engineering design practices based on the American Association of State Highway and Transportation Officials (AASHTO) regulation “A Policy on Geometric Design of Highways and Streets” or other appropriate/approved methods. The Zoning Administrator and Compliance Coordinator shall determine what an adequate design for acceleration/deceleration access lanes shall be, or other improvements, based on appropriate engineering standards.
(D) Other than construction of a single-family dwelling on an existing lot, all development, including the creation of a lot through the claim of exemption process, shall require that roads linking the development to a county- or state-maintained road shall be a minimum of 50 feet of right-of-way or road and utility easement with a minimum width of 24 feet of improved roadway unless a lesser width is approved by the Zoning Administrator. Based on an analysis by a professional engineer, the Zoning Administrator may reduce the required width to not less than 30 feet of right-of-way or road and utility easement and 20 feet of improved roadway if it is determined the lesser standard is sufficient for the potential traffic based on the potential number of lots served by the right-of-way and allowed uses under current zoning. Composition of the road surface shall be by design to withstand the proposed loading. Width and design may vary depending upon the use. Drainage swales and drainage structures shall be part of the road design.
(E) Driveways shall be spaced a minimum of 150 feet from an intersection or a driveway used for off-street parking. For lots where this is not possible, driveways shall be spaced as far from the intersection as practical. Conflicts with adjoining driveways, exits and entrances will be spaced to create the safest possible conditions for traffic movement and shall be justified by engineering analysis. Driveways linking residential development to a county- or state-maintained road or private easement shall meet the following standards: the drivable width shall be 25 feet wide for two-way traffic and 20 feet for one-way traffic, the maximum length shall not exceed 150 feet and shall serve not more that driveway and/or four dwelling units unless the site plan is approved by the County Fire Marshal.
(F) Private roadway easements shall be maintained by adjacent property owners. New private roadway easements shall include a statement that adjacent property owners area responsible for maintenance. Such road maintenance agreements must be filed when a building permit or mobile home permit is issued.
(G) Existing substandard road easements in designated “colonias” are subject to the requirements for maintenance as outlined in division (F) above.
(H) All development shall provide for a clear sight triangle at all intersections with or between all public and private roads; and off-street multiple parking area entrances, exits; driveways to and from public and private roads; and at any unique geometrical situation involving horizontal, vertical and skewed intersections or driveways (see example in Appendix E, attached to the ordinance incorporated herein). The County Transportation Department may rely upon the American Association of State Highway and Transportation Officials (AASHTO) publication “Policy on Geometric Design of Highways and Streets”, dated 1990 (and amendments thereto), in determining the appropriate design requirements for the particular intersection at issue.
(1) A clear sight triangle (as shown in Appendix E, attached to the ordinance incorporated herein) shall be an area of unobstructed vision, beginning at a point three feet above the finished grade of the road at the lowest adjacent point on the edge of the pavement, and bounded by one of the following:
(a) The front and side property lines of a corner lot and a line connecting points 30 feet from the intersections of the property or roadway easement lines of the lot;
(b) The front and side lines of a private driveway, exit or entrance and a line connecting points 15 feet from the intersection of the corner of the lines of the private driveway, exit or entrance; or
(c) The front and side lines of a public or off-street multiple parking area driveway, exit or entrance and a line connecting points 30 feet from the intersection of the corners of the lines of the public or off-street multiple parking are driveway, exit or entrance.
(2) Within the clear sight triangle, no structure, including, but not limited to, signs or walls, shall be constructed or erected higher than three feet from the edge of the pavement, except that barbed wire or other fences that do not obstruct the view of the roadway shall be allowed. No trees, shrubs or other vegetation that would normally grow to a height of three feet from the edge of the pavement shall be planted within the clear sight triangle.
