(1) Following approval of the preliminary plat by the council, the applicant shall file with the plat administrator three complete sets of preliminary construction plans and specifications prepared by a professional engineer licensed by the state of Washington showing all street and utility improvements as required by the council in granting approval of the preliminary plat. The construction plans and specifications shall be accompanied by a minimum plan check fee as per the rate schedule established by the city engineer. All construction plans and specifications shall be in conformance with city design standards and the community street and utility standards. Sheet size shall be 24 inches by 36 inches and shall have a border of one inch on the left margin and one-half inch on the remaining three margins. The scale shall be five feet vertically and 40 feet horizontally.
(2) The preliminary construction plans and specification shall be forwarded to the city engineer by the plat administrator. The city engineer shall approve, conditionally approve, or disapprove the plans. The subdivider shall submit one set of permanent reproducible Mylar and three sets of specifications which have been approved for the city engineer’s signature, records, and use.
(3) After the city engineer has approved the construction plans and specifications, the subdivider shall complete and install all street and utility improvements required by the council in granting preliminary plat approval prior to filing of the final plat. A one-year maintenance bond shall be required in the amount determined pursuant to ECMC 17.17.130(1)(b).
(4) The public works department or a licensed professional engineer or engineering firm hired by the city shall be responsible for the inspection of all subdivision improvements to ensure conformance with the approved plans and specifications.
(5) In lieu of completing and installing all required street and utility improvements prior to filing of the final plat with the plat administrator, the subdivider may post a subdivision bond or other approved security in a form satisfactory to the city attorney. The subdivision bond or approved security shall be in an amount equal to 150 percent of the estimated cost as determined by the city engineer, of such improvements required by the council in granting approval of the preliminary plat. In the event that all street and utility improvements are not completed within the time limit specified in the subdivision bond or approved security, the bond or security may be forfeited and the city may undertake the installation and completion of all required street and utility improvements.
(a) All street and utility improvements listed in the subdivision bond must be installed, completed and accepted by the city within two years of council approval of the final plat.
(b) The planning commission may grant one extension of the subdivision bond or security for a period not to exceed two years; provided, that the request for an extension is filed with the plat administrator at least 60 days prior to the expiration date of the bond or security.
(c) In the event that time extension is granted, a new subdivision bond or other approved security shall be submitted in an amount sufficient to cover 150 percent of the cost of completing utility extensions and street improvements. The bond will be updated with new estimates of cost on all uncompleted improvements and all increased cost estimates shall be passed onto the bond. If these increased costs are not accepted by the surety, then the city shall foreclose on the bond and the plat will be held in abeyance. Departments issuing recommendations for new subdivision bonds or other approved security shall not modify the terms and requirements of the bond or security other than to pass on all increased cost estimates as determined by the city engineer to the bond or security to cover the cost of completing utility extensions and street improvements without the written consent of the applicant.
