17.10.030 Improvements and dedications.

(1) Requirements Before Recordation. The improvements required by this title shall be constructed, installed and maintained by the subdivider until accepted by the municipality prior to recording the final plat in the office of the county recorder, unless the construction, installation, and maintenance is guaranteed in the manner provided in this title. Improvements shall not be installed or constructed until their design and specifications have been approved by the city.

(2) Guarantee of Improvements. In lieu of the actual completion and acceptance by the city council of the improvements required by this title, the subdivider shall guarantee the installation and construction of the required improvements within one year from the date of recordation of the final plat by one or more of the following methods:

(a) Bonds. In order to ensure that the development will be constructed to completion in an acceptable manner, the applicant (owner) shall enter into a bond agreement to guarantee construction of dedicated improvements. Said bond agreement shall include either an escrow deposit, letter of credit, or surety bond issued by a bonding company licensed to do business in the state of Utah, which posts or deposits a financial guarantee with the city in an amount equal to 100 percent of the costs to construct dedicated improvements, as estimated by the city engineer. All financial instruments offered to the city to ensure the construction of public improvements shall be approved as to legal form by the city attorney. The agreement and escrow deposit shall assure timely construction and installation of all required public improvements. Developer may not seek release of individual public improvements from coverage under the bond agreement before all public improvements are ready to be dedicated. The developer may request partial bond releases of whole categories of improvements within the bond. Ninety percent of the entire bond may be released when 100 percent of the site is complete, inspected, accepted by the city and approved by the city council. The remaining 10 percent will be held to insure that the improvements shall be maintained in a state of good repair for a period of 12 months from the date of completion and acceptance by the city inspector for all improvements bonded. The final release must receive approval by the city council.

(b) Inadequate Bond. If the bond proceeds are inadequate to pay for the cost of the completion of the improvements according to the city’s standard of specifications for whatever reason, including previous reductions, the subdivider shall be responsible for the deficiency and no further building permits shall be issued in the subdivision until the improvements are completed or, with the city council’s approval, a new, satisfactory bond has been executed and delivered to the city or other satisfactory arrangements have been made to insure completion of the remaining improvements.

(c) Electronic Version of As-Constructed Drawings. Prior to acceptance of the subdivision, as-constructed drawings shall be turned in to the city engineer in both an electronic format which is acceptable to the city engineer and in 22-inch by 34-inch drawings.

(3) Acceptance of Dedicated Streets and Improvements. The dedication of the streets and other improvements required by this title shall be deemed an offer by the subdivider which shall be kept open for at least two years and may not be withdrawn during that time. The city shall accept the offer of dedication only if it finds that the subdivider has constructed, installed and maintained the improvements required by Riverton City Standard Specifications and Plans Manual and the improvements comply with the minimum requirements of Riverton City Standard Specifications and Plans Manual at the time of acceptance. [Ord. 15-23 § 1 (Exh. A); amended during 2011 recodification; Ord. 07-13 § 1; Ord. 9-26-06-1 § 1 (Exh. C); Ord. 8-17-99-1 § 1 (Exh. A); Ord. 2-3-98-1 § 1 (Exh. A). Code 1997 § 12-325-020-C.]

(2) Changes on Plats without Approval. It shall be unlawful for any person to change the lines, drawings, lot sizes or shapes, or any other provision of a plat after it has received approval by any person whose approval is required. Any plat that is changed in violation of this subsection is void and the subdivider may, upon conviction thereof, be punished to the extent of the law for violation of a misdemeanor. In addition, the city may compel the person recording the plat to withdraw the plat from the county recorder’s office or to file a notice, or the city may itself file a notice that the recordation of the plat is void.
