Subject: “On Hold” Notice

Dear Mr. Kitzes:
The Planning Division of the City of Renton accepted the above master application for review on
December 6, 2017. During our review, staff has determined that additional information is necessary in
order to proceed further.
The following information will need to be submitted before April 11, 2018 so that we may continue the
review of the above subject application:
Under a previous land use application made for this site (LUA05-089, SHPL-H, ECF), the City of
Renton received professional studies identifying several onsite streams and one onsite wetland.
A copy of some of the exhibits and figures from these previous report are included as an
attachment for your reference (Attachment A). A copy of the land use file is available in
Laserfiche through the Office of the City Clerk. Please revise and resubmit a Critical Areas Report
that identifies and evaluates all existing critical areas onsite. Submitted reports shall comply
with all current Critical Area Regulations of the Renton Municipal Code (RMC). Please note that
the City may require an independent review of an applicant’s report when appropriate due to
lack of substantial documentation of impact avoidance as part of the first study. Evaluation by
an independent qualified professional is paid for at the applicant’s expense and is selected by
the City (RMC 4-3-050F.6.a).
A preliminary drainage plan and Technical Information Report (TIR) prepared by Core Design
dated August 21, 2017 were submitted to the City as part of the site plan submittal. The site is
located in the City’s Flow Control Duration Standard (Forested Site Conditions). The site is
located in the Thunder Hills Creek drainage basin. The TIR was not completed in accordance
with the standards found in the 2017 Renton Surface Water Design Manual (RSWDM). All nine
core and six special requirements were not addressed. For example:
o Due to the re-routing of surface water through the steep slopes onsite the final TIR
needs to include a Level 2 downstream analysis for the proposed adjustments to the
drainage path to satisfy Core Requirement #2, Offsite Analysis. The analysis will
need to discuss the potential increase in erosion due to the increase amount of
water volume.
o Conveyance calculations were not provided in the preliminary TIR. Conveyance
calculations shall be included in the final TIR to satisfy Core Requirement #4,
Conveyance System.
o A geotechnical report evaluating site soil conditions was prepared by the Riley
Group dated March 14, 2017. The report recommends to not use any type of
infiltration systems onsite due to the surface and subsurface conditions.
One of the content requirements for a Geotechnical Report with medium and high coal mine
hazards is to utilize test pits to investigate coal mine waste dumps and other shallow hazards
such as slope entry portals and shaft collar areas. Drilling is required for coal mine workings or
other hazards that cannot be adequately investigated by surface investigations. Please verify
that the Geotechnical Report was prepared in accordance with the content requirement for all
onsite geologic hazards (RMC 4-8-120D.7). All geotechnical reports prepared for geologically
hazardous areas will be subject to an independent review by a qualified specialist selected by
the City, at the applicant’s expense (RMC 4-3-050F.6.b).
Please revise and resubmit all plans and application submittal items that are impacted through
updated reports.
Please provide me with a response to two (2) Public Comment Letters received by the City of
Renton on January 5, 2018 (Attachment B).
At this time, your project has been placed “on hold” pending receipt of the requested information.
Please contact me at (425) 430-7289 if you have any questions.
Sincerely,
Clark H. Close
Senior Planner
