COMMENTS RESPONSE LETTER
11410 SE Petrovitsky Rd, Renton, WA 98055
Dear Valerie Porter,
We addressed your comments provided from the planning division for this project
on January 23, 2026.
The City’s landscape regulations (Renton Municipal Code (RMC) 4-4-070 require a
10-foot landscape strip along all public street frontages. While the site plan shows
a 10-foot-wide landscape strip, it does not provide details of the proposed
vegetation. Please submit a landscape plan that details plant locations and a plant
schedule specifying species, size, and quantity.
A landscape plans set is submitted in this review cycle.
The subject parcel is allowed to have one driveway. Please submit a revised site
plan decommissioning the second driveway and providing vegetation to the right-
of-way.
This comment has been addressed in the revised site plan.
• According to RMC 4-4070F.4, a nonresidential development in a residential zone
is required to provide either a fifteen-foot (15') wide partially sight-obscuring
landscaped visual barrier, or ten-foot (10') wide fully sight-obscuring landscaped
visual barrier along shared property lines. Please provide a revised landscape plan
showing the required screening.
A landscape plans set is submitted in this review cycle.
• The most recently submitted site plan identifies eight (8) existing trees on the
project site, which conflicts with the Tree Retention Worksheet that lists 5 existing
trees. To resolve the discrepancy, please submit an updated landscape plan clearly
identifying trees proposed for removal and retention, along with a revised Tree
Retention and Credit Worksheet that is consistent with the site plan.
A landscape plans set is submitted in this review cycle.

• The parking lot layout does not comply with the most recently approved Code
Interpretation. The minimum parking space dimensions are eight feet (8’) in width
by twenty feet (20’) in length. Please revise the site plan to demonstrate
compliance.
A landscape plans set is submitted in this review cycle.
• Per RMC 4-4-090B.3, refuse, recyclables, and compostables deposit areas may
not be located within fifty feet (50') of a lot zoned residential, unless approved
through the site development plan review process or the applicable modification
process. The site plan shows the waste container and associated enclosure within
the side setback, which is not permitted. Please submit a revised site plan showing
the new location for the waste containers outside of the required setbacks.
The revised site plan is showing a new location for the waste containers outside
the required setbacks.
• The project site is required to provide on-site lighting. Please submit an
illumination plan demonstrating compliance with RMC 4-4-075, Lighting, Exterior
On-site. The illumination plan(s) must depict the type of lighting proposed, the
direction of the lighting, and the location of all of the exterior lights.
An illumination plan is submitted on this cycle.
• It has been discovered additional structures have been added to the project site.
Please submit revised plans show all existing and proposed structures on the
project site.
Submitted.
• Multiple sources, including City of Renton (COR) Maps, King County iMap, aerial
imagery, LiDAR data, field reconnaissance, and public comments, indicate that a
large area on the north side of the parcel has undergone vegetation removal and
substantial clearing, grading, and fill. This conflicts with the most recent site plan
submitted to the city for review, which depicts the area as existing vegetation.
Staff estimates that approximately 12,000 square feet of area has been cleared,

and 750-1,000 cubic yards of fill has been placed on the project site. While initial
clearing on the project site (APN 2923059025) occurred between 2009 and 2012,
evidence shows clearing and grading has expanded onto the northern parcel (APN
2923059157) in 2019.
All the unauthorized clearing and fill dumping will be restored as shown on the
submitted landscape plans.
City records indicate the parcel (APN 2923059157), directly north of the project
site, contains a stream, a wetland, and associated buffers that may encroach onto
the project site. To proceed with the land use review, the following information
must be provided:
o Wetland Report: A report prepared by a qualified professional documenting
critical area boundaries and buffers, assessing functions and impacts, and
identifying mitigation measures.
Wetland Report has been prepared and submitted on this review cycle.
o Technical Information Report (TIR) / Drainage Report: A report prepared by a
qualified professional accounting for all existing and proposed structures on the
project site, prior work conducted on the north side of the project site and
adjacent parcel to the north, and all new or replaced impervious surfaces,
including the large asphalt area along SE Petrovitsky Rd that was paved between
2017 and 2019. This area must be included in drainage and water quality
threshold calculations. Thresholds must also account for areas converted from
forest or vegetation to gravel unless a restoration plan is proposed. Please note
that exemptions from flow control and water quality requirements may likely be
met without large-scale restoration.
City staff has received public comments and supporting documentation from an
adjacent property owner indicating that clearing and grading activities on the
project site and parcel immediately north have adversely affected their property,
which has resulted in multiple flooding events. The TIR/Drainage Report must
evaluate potential impacts to wetland hydrology and downstream properties in
accordance with the 2022 Renton Surface Water Design Manual and evaluate
downstream flooding impacts to neighboring properties.

Per the meeting held with the Michael Sippo and Valerie Porter on June 11th
virtually at 1pm. The report will be revised to model predeveloped as forest and
the mitigated areas as lawn since restoration will be done as indicated on the
landscape plans submitted on this round.
Per the meeting Michael confirmed that since the restoration will be completed
on both the north of the property and the adjacent property on the north side,
there is no need to include the wetland in the drainage report, and no need to
assess the impact on the wetland.
The existing asphalt area along SE Petrovitsky Rd as shown on the survey mapping
has been considered in the TIR report.
