REVIEW PROCESS
The platting process is comprised of three (3) basic steps:
1. Preliminary Plat Application;
2. Installation of street and utility improvements according to the approved Preliminary Plat; and
3. Final Plat Application.
This handout covers only the first step in the process — the Preliminary Plat Application and approval process.
Once a complete land use application package has been accepted for initial review, the Planning Division will post mail
notices to property owners within 300 feet of the project site and post the notice on the City's webite. The proposal
will be routed to other City departments and other jurisdictions or agencies that may have an interest in the
application. The reviewers have two (2) weeks to return their comments to the Planning Division. Within approximately
two weeks, the Planning Division will prepare a report regarding the proposal's compliance with applicable codes and
the City's review criteria.
The application will then be presented to the City's Environmental Review Committee. The Environmental Review
Committee (ERC) is comprised of the Administrator of Public Works, the Administrator of Community and Economic
Development, the Administrator of Community Services, and the Fire Chief. The Committee is responsible for
determining whether the proposal will result in significant adverse environmental impacts. To do this, the committee
will consider such issues as environmental health hazards, wetlands, groundwater, energy and natural resources and
will then issue its decision (Environmental Threshold Determination).
The Environmental Review Committee will either issue a:
• Determination of Non -Significance (DNS) -Make a determination the proposal will have no significant negative
environmental impacts; or
• Mitigated Determination of Non -Significance (DNS-M)-Make a determination the proposal, if modified, would
have no significant negative environmental impacts; or
• Determination of Significance (DS)-Make a determination the proposal will have significant adverse environmental
impacts and require the applicant to submit an Environmental Impact Statement (EIS) prepared by a qualified
consultant.
Once the Environmental Review Committee has issued its Environmental Threshold Determination (provided an EIS is
not required), a public notice of the Determination is issued and posted on the City's website. A 14-day appeal period
commences following the publication date. At the discretion of the City, a separate and additional 15-day comment
period may be added prior to the 14-day appeal period.
After the fourteen (14) day appeal period has ended, the project can be scheduled for public hearing before the City
Hearing Examiner, provided no appeals have been filed.

PRELIMINARY PLAT
HEARING EXAMINER PERMIT REVIEW AND REVIEW OF ENVIRONMENTAL DETERMINATION APPEALS
A public hearing is required. After review of the proposal and any staff or public comments, the Planning Division staff
will forward a report and recommendation and the Environmental Review Committee decision to the Hearing Examiner
prior to the hearing. This report will be mailed to all persons listed on the Master Application and all parties of record.
Notice of the public hearing will be published in the local newspaper at least 10 days prior to the hearing. Applicants
are strongly encouraged to attend the public hearing for their proposal. City staff will first make a presentation to the
Hearing Examiner about the proposal. Then the applicant and any citizens in support of the proposal will give
testimony. When giving testimony, names and addresses must be stated for the record. Following this, individuals with
neutral or opposing comments will give their testimony to the Hearing Examiner. City staff or the applicant will address
additional questions raised throughout the hearing. The Hearing Examiner will review the application concurrently with
any environmental appeals and issue a final decision(s) within fourteen (14) days of the hearing unless, at the time of
the public hearing, the Hearing Examiner indicates additional time will be required for issuance of the decision. The
decision to approve, conditionally approve, or deny the proposal will be mailed to all persons listed on the Master
Application and all parties of record.
APPEAL AND RECONSIDERATION PROCESS FOR DECISIONS
Any person, including the applicant, aggrieved by the granting or denial of an application, may make a written
application for reconsideration to the Reviewing Official within 14 calendar days of the date of the decision. After
review of the request, the Reviewing Official may take whatever action is deemed proper. The Reviewing Official's
written decision on the reconsideration request will be mailed to all parties of record within 10 days from the date the
request was filed. If any party is still not satisfied after a reconsideration decision has been issued, an appeal may be
submitted within 14 days to:
• The Hearing Examiner for Administrative decisions
• The City Council for Hearing Examiner decisions
An appeal may be filed without first requesting reconsideration by the Reviewing Official; however, it must be filed
within 14 days of the date when the original decision was issued. See RMC 4-8-110 for further information on the
appeal process and time frames.
BUILDING AND CONSTRUCTION PERMIT ISSUANCE AND INSTALLATION OF IMPROVEMENTS
In the City of Renton, a Building Permit must be obtained to build buildings and structures. A Construction Permit must
be obtained to install utility lines, transportation improvements and undertake work in City rights -of -way. Building and
Construction Permits are separate permits.
Applicants may apply for building and construction permits concurrently with their request for a land use application.
However, the applicant should be aware any conditions of land use permit approval may create a need for revisions to
other permit applications whereby additional fees may be charged. Refunds of building permit charges are not
available.
If no appeals or reconsideration requests are filed within 14 days of the effective date of the decision to approve the
application, the applicant may obtain building and construction permits. A construction permit for the installation of
on -site and off -site utilities will be issued upon the review and approval of civil engineering drawings by the
Development Engineering Section and receipt of all applicable development and permit fees. A building permit will be
issued upon the Building Section's approval of building plans and receipt of all applicable fees.
INSTALLATION OF IMPROVEMENTS
Prior to applying for Final Plat approval, all required improvements must be installed. The developer shall obtain all
necessary construction permits and pay all fees and inspection costs. Typically, a Final Plat application cannot be
processed until required improvements have been satisfactorily installed.

PRELIMINARY PLAT
DEFERRAL OF IMPROVEMENTS
If a developer wishes to defer certain on -site or off -site improvements (i.e. landscaping, curbs and sidewalks), written
application with full and complete engineering drawings must be submitted to Development Engineering. The
application should explain the reasons why such delay is necessary. If approval is granted, security in the form of an
irrevocable letter of credit, set -aside fund, assignment of funds or certified check shall be furnished to the City in an
amount equal to a minimum of 150% of the estimated cost of the required improvements.
EXPIRATION AND EXTENSIONS
Once an application has been approved, the applicant has five (5) years to comply with all conditions of approval and to
submit for Final Plat before the approval becomes null and void. In order to revitalize an expired Preliminary Plat, a
new application must be submitted to the Planning Division. One one-year extension shall be granted to an applicant
who files a written request with the Administrator at least thirty (30) days before the expiration of this five (5) year
period, provided the applicant demonstrates that he/she has attempted in good faith to submit the final plat within the
five (5) year period. It is the responsibility of the sub -divider to monitor the expiration date.
ADDITIONAL EXTENSIONS
Additional time extensions beyond this one-year time period may be granted by the Hearing Examiner if the applicant
can show need caused by unusual circumstances or situations which make it unduly burdensome to file the final plat
within the five (5) year time period. The applicant must file a written request with the Hearing Examiner and the CED
Department for this additional time extension; this request must be filed at least thirty (30) days prior to the plat
expiration date. The request must include documentation as to the need for the additional time period.
PHASED SUBDIVISION
In the case of a phased subdivision, final plat approval by the Hearing Examiner of any phase of the preliminary plat will
constitute an automatic one-year extension for the filing of the next phase of the subdivision.
PLAT AMENDMENTS
At any time after preliminary plat approval and before final plat approval, the applicant may submit an application to
the Administrator that proposes an amendment to the approved or conditionally approved preliminary plat. The
Administrator shall have the authority to determine whether the proposed amendment qualifies as a major or minor
amendment.
MAJOR PLAT AMENDMENTS
Major amendments to an approved or pending plat application shall require a new application. For major amendments
that due to extraordinary circumstances would result in a highly unreasonable and unconscionable burden on the
applicant or plat holder, if the applicant or plat holder was required to go through a new application process, the
Administrator may permit the major amendment to be treated as a minor amendment.
MINOR PLAT AMENDMENTS
Minor plat amendments may be reviewed and permitted as part of final plat approval. To be considered a minor
amendment, the amendment must not:
• Decrease the aggregate area of open space in the subdivision by ten percent (10%) or more;
• Increase the number of lots in the subdivision beyond the number previously approved;
• Result in a violation of development standards;
• Relocate any roadway access point to an exterior street from the plat;
