The improvement plan stage of the major subdivision approval process is for the purpose of accurately showing how subdivision improvements (streets and drainage facilities, for example) will be constructed in order to conform to the layout and design objectives of the preliminary plat and the standards of this chapter.
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
(A) Improvement plans may be submitted with the preliminary plat or the developer may choose to obtain preliminary plat approval before submitting detailed improvement construction plans, in which case improvement plans may be submitted before or concurrently with submittal of the final plat.
(B) When conditions warrant, the Chief Subdivision Engineer may require that preliminary engineering or improvement plans be submitted during the preliminary plat review process in order to determine the land’s suitability for the preliminary plat design. Any required off-site improvements and engineering studies must be provided upon request of the Chief Subdivision Engineer.
(C) If only a single portion or phase of the subdivision will be submitted for final plat approval and the phasing plan has been approved at the time of preliminary plat approval, improvement plans need be prepared for only that phase. However, the entire area of the proposed subdivision, as well as any additional area necessary to properly design facilities, must be the basis for design and must be so indicated.
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
(A) The Chief Subdivision Engineer must review improvement plans to determine if the plans comply with all applicable regulations of this chapter and county standards and specifications.
(B) If the Chief Subdivision Engineer determines that the improvement plans do not comply with applicable regulations and standards, the Chief Subdivision Engineer is authorized to require that modifications be made to bring the improvement plans into compliance with regulations and standards.
(C) After conducting a complete review of the improvement plans, the Chief Subdivision Engineer must approve or deny the application for improvement plan approval.
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
Before approval of the improvement plans, the applicant must submit to the Chief Subdivision Engineer and to all approving agencies and to public utility companies that will service the subdivision a general schedule of the timing and sequence for construction of all required improvements.
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
Except upon the written approval of the Chief Subdivision Engineer, no grading, removal of trees or other vegetation, land filling, construction of improvements or other material change, except for the purpose of aiding in preparation of final engineering drawings or plans, may begin on the subject property until the applicant has:
(A) Received a site development permit from the Chief Subdivision Engineer; and
(B) Obtained necessary approvals and permits from other affected municipal, county, state or federal agencies.
(Ord. passed 7-8-1970; Res. 09-167, passed 6-18-2009)
When a subdivision is to be developed in one or more phases, developers must install public improvements or post financial guarantees for each phase. The county may require public improvements to be installed or financial guarantees to be posted for areas beyond an individual phase if the county determines that improvements or guarantees are necessary to ensure the relative self-sufficiency of the development phase, pending completion of the entire subdivision.
