Title 18 - Unified Development Ordinance

18.460.260 Required Improvements - Streets

For purposes of this Section: “Interior Street” means a public street whereby the entire public street and right-of-way is located within the platted boundary of the development. A “Perimeter Street” means a public street contiguous to the plat boundary where a portion of the public street right-of-way is outside of the plat boundary.  As used in this Section, the term “Standards” shall have the same meaning as set forth in Section 13.10.010 of the Code.

1. A.
   Interior Streets: The subdivider shall be responsible for the installation of all Interior Streets and associated appurtenances within the boundaries of the subdivision. No grading or other construction shall take place within a street right-of-way until the construction plans have been approved by the City Engineer. All street construction must comply with the Standards, and compliance therewith must be confirmed by the City Engineer prior to release of any surety required hereinafter. For new Interior Streets designated as thoroughfares on the City’s official street map, the subdivider shall be responsible for construction of an interim thoroughfare in compliance with the Standards.
2. B.
   New Perimeter Streets - Collector and Super-Collectors: Where a subdivision abuts a proposed super-collector or collector street where no street currently exists, the subdivider shall pay the City an amount equal to one-half of the cost of the design and construction of a super-collector or a collector street complying with the Standards. Said amount shall be either determined or approved by the City Engineer, and is to be based upon the work involved, including but not limited to, design, survey, construction and permitting costs. The subdivider shall deposit said amount in cash with the City’s Director of Budget and Finance, for designation in the street improvements escrow funds. The Governing Body may waive all or a portion of the payment required by this Section in such cases where it determines that the circumstances are unique and compensating benefits are provided to the public.

Where feasible based upon available right-of-way and easements, the subdivider may, with approval of the City, construct an equivalent length of Perimeter Street in lieu of escrowing funds. In cases where additional length of said street is required to provide required access and circulation within the proposed development, the subdivider shall be responsible for said construction as part of the development process.

3. C.
   New Perimeter Streets - Thoroughfares: Where a subdivision abuts a proposed thoroughfare as shown on the City’s Official Street Map and where no street currently exists, the subdivider shall be responsible to construct any portion of the thoroughfare necessary to achieve sufficient access and site circulation. Said street shall be constructed as an interim thoroughfare in compliance with the Standards.
4. D.
   Existing Perimeter Streets - Collectors, Supercollectors, and Thoroughfares: In the case of a subdivision which abuts an existing or proposed collector, super-collector or thoroughfare street that does not contain a paved surface conforming to the Standards, the following standards and procedures shall apply:

   1. 1.
      If the street consists of seal-coated surface, crushed rock or material other than asphaltic concrete, or if the pavement is less than 22 feet in width and three inches in depth, or has an irregular or deteriorated surface as determined by the City Engineer, the subdivider shall improve the length of such street abutting the subdivision as part of the subdivision development process. Such improvement shall consist of up to a 3-inch overlay 24 feet in width, as determined by the City Engineer.
   2. 2.
      In lieu of making the required improvements set forth in subsection (D)(1), the subdivider may, subject to the approval of the Director, voluntarily choose to enter into an agreement with the City whereby the subdivider deposits in cash with the City’s Director of Budget and Finance a street maintenance escrow equivalent to the estimated cost of a 3-inch asphaltic concrete overlay from the edge of the street to the street centerline for the platted frontage and for the cost of a full depth widening of the street. 

      1. a.
         Costs shall be based on widening of at least a 2-foot wide section, to a minimum overall street width of 22 feet, along the platted frontage.  The cost shall be determined by the City Engineer on an annual basis and shall be based upon a review of recent bid prices for roadway surfacing, restriping, traffic control, and other associated costs for a maintenance overlay. Such funds shall be set aside for future maintenance and/or widening of the abutting street, either by the City or a third party. Funds shall be used to defray maintenance and/or widening costs.
      2. b.
         In such event, these funds shall be the only financial contribution paid by the subdivider or its successors in interest related to existing unimproved collector, supercollectors, and thoroughfare maintenance and repairs. Said funds shall not be utilized towards ultimate reconstruction of the street to improved standards.
      3. c.
         The City Engineer may maintain a map that is updated on a periodic basis which determines which streets are eligible for the street maintenance escrow fund option based on an evaluation of pavement section, condition, and width.

4. E.
   In addition to requirements of A-D above, the subdivider shall also perform whatever grading is necessary so that the subdivision grades are compatible with those depicted for any adjacent proposed collector, super-collector or thoroughfare street in street plans available from the City Engineer. In the event that preliminary or final street plans have not been prepared for the collector, super-collector or thoroughfare street, the subdivider must furnish a preliminary street plan in compliance with the Standards. Plans and specifications for said pavement and grading, and where applicable preliminary street plans shall be approved by the City Engineer in the same manner as other construction in the City. Preliminary street plans shall be approved by the City Engineer, and will be kept on file in the office of the City Engineer.
