An application may be submitted for any proposed revision to a preliminary subdivision or preliminary short subdivision. The application shall contain the signatures of the parties having an ownership interest in the preliminary short subdivision or subdivision and shall be reviewed as a Type I land use decision under RMC Title 19.
(Ord. 2024-06 § 1)
A. 
A request to revise a subdivision or short subdivision that has received preliminary approval shall be submitted to the development services department.
B. 
Proposed revisions to a preliminary subdivision that would result in a substantial change, as determined by the administrator, shall be treated as a new application for purposes of vesting and transportation concurrency, and shall be reviewed as a Type III land use decision under RMC Title 19.
C. 
Proposed revisions to a preliminary short subdivision that would result in a substantial change, as determined by the administrator, shall be treated as a new application for purposes of vesting and, where applicable, transportation concurrency, and shall be reviewed as a Type I land use decision pursuant to RMC Title 19.
D. 
For the purpose of this section, a substantial change includes, but is not limited to:
1. 
Any revision that would result in or would have the effect of decreasing the aggregate area of open space in the subdivision by 10 percent or more;
2. 
Any revision that would result in increasing the number of lots in the subdivision beyond the number previously approved;
3. 
Any revision that would result in the relocation of any roadway access point as it connects to an exterior street from the plat;
4. 
Any revision that proposes phasing of plat development when no phasing plan was included in the original preliminary subdivision approval; or
5. 
Any revision that, in the opinion of the administrator, would significantly increase any adverse impacts or undesirable effects of the plat;
6. 
A change to conditions of approval of an approved preliminary subdivision or preliminary short subdivision that leads to environmental impacts that were not addressed in the original approval.
E. 
Proposed revisions to a subdivision or short subdivision that do not result in a substantial change, as determined by the administrator, shall be treated as a minor change and may be approved administratively by the administrator as a Type I land use decision pursuant to RMC Title 19.
F. 
For purposes of this section, minor revisions include, but are not limited to:
1. 
Revisions to engineering design standards necessitated by changed circumstances, such as reconfiguration or reduction of lots;
2. 
Revisions in lot dimensions that are consistent with the underlying zone;
3. 
A decrease in the number of lots to be created so long as the minimum lot size and minimum density of the underlying zone is maintained;
4. 
Revisions in timing of phased plans; and
5. 
Revisions to engineering design that reduce construction-related impacts and do not eliminate off-site improvements specifically required as a condition of preliminary approval.
