Approval of the preliminary plat shall constitute authorization for the subdivider to develop the subdivision's facilities and proceed with design of improvements in strict accordance with standards established by this title and any conditions imposed by the board. Design approval by the county public works director shall be obtained prior to commencement of construction of subdivision improvements.
(Ord. 2005-31, 2005)
A final plat meeting all requirements of this chapter shall be submitted to the board for approval within the timeframe specified by RCW 58.17.140. Failure to do so will result in the preliminary plat being expired and no longer valid. No further action is necessary regarding an application once the preliminary plat has expired pursuant to this chapter. Any applicant who files a written request with the administrator at least 30 days prior to the expiration date, showing that the applicant has attempted in good faith to submit the final plat within the time period and that the associated fees are paid, shall be granted a one-year extension. Such an extension can be requested and granted five times.

1. 
A request to revise a plat, short plat, or binding site plan that has received preliminary approval shall be submitted to the department.
2. 
Proposed revisions to a preliminary subdivision that would result in a substantial change, as determined by the department, shall be treated as a new application for purposes of vesting and transportation concurrency.
3. 
Proposed revisions to a preliminary short subdivision or binding site plan that would result in a substantial change, as determined by the department, shall be treated as a new application for purposes of vesting and, where applicable, transportation concurrency.
4. 
For the purpose of this section, a substantial change includes, but is not limited to:
a. 
The creation of additional lots;
b. 
The reduction or elimination of open space;
c. 
A change in use;
d. 
A change in points of ingress or egress; and
e. 
A change to conditions of approval of an approved preliminary subdivision, preliminary short subdivision or binding site plan that leads to environmental impacts that were not addressed in the original approval.
