A. Following approval of the preliminary plat by the Plat Administrator, the applicant shall file with the Plat Administrator, three (3) 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 Plat Administrator in granting approval of the preliminary plat. All construction plans and specifications shall be in conformance with city Design Standards and the Community Street and Utility Standards. Sheet size shall be twenty-four inches (24") x thirty-six inches (36") and shall have a border on one inch (1") on the left margin and one half inch (½") on the remaining three margins. The scale shall be five feet (5') vertically unless grades exceed ten percent (10%) and forty feet (40') horizontally.
B. The preliminary construction plans and specifications shall be forwarded to the City Engineer within two (2) working days of receipt by the Plat Administrator. Within twenty (20) calendar days of filing of the plans with the Plat Administrator the City Engineer shall approve, conditionally approve, or disapprove the plans. The subdivider shall submit one (1) set of permanent reproducible mylar and three (3) sets of specifications which have been approved for the City Engineer's signature, records, and use.
C. 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 Plat Administrator in granting preliminary plat approval prior to filing of the final plat. A one (1) year maintenance bond shall be required in the amount of one hundred percent (100%) of the construction cost.
D. 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 insure conformance with approved plans and specifications.
E. 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 one hundred fifty percent (150%) of the estimated cost as determined by the Public Works Director, of such improvements required by the Plat Administrator 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.
1. All street and utility improvements listed in the subdivision bond must be installed, completed, and accepted by the city within one (1) year of approval of the final plat by the Plat Administrator.
2. The Plat Administrator may grant one (1) extension of the subdivision bond for a period not to exceed one (1) year provided that said request for an extension is filed with the Plat Administrator at least sixty (60) calendar days prior to the expiration date of the bond.
3. In the event that a time extension is granted, a new subdivision bond or other approved security shall be submitted in an amount sufficient to cover one hundred and fifty percent (150%) 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 Public Works Director to the bond or security to cover the cost of completing utility extensions and street improvements without the written consent of the applicant.
