PROJECT NUMBER: LUA24-000040, ECF, CAE
PROJECT NAME: Wolde Critical Area Restoration
PROJECT MANAGER: Andrew Van Gordon, Associate Planner
APPLICANT/CONTACT: Kerrie McArthur, Confluence Environmental Company
146 N Canal St Suite 111, Seattle, WA 98103
OWNER: Elias Wolde
13701 SE May Valley Rd, Renton, WA 98059
PROJECT LOCATION: 13701 SE May Valley Rd, Renton, WA 98059 (APN 3424059113)
PROJECT DESCRIPTION: The applicant is requesting approval of a Critical Areas Exemption to allow for the
restoration of 7,000 square feet within the critical area buffer of May Creek at 13701 SE May Valley Rd (APN
3424059113). The property is 22,771 square feet (0.52 acre) in size. The property is located within the Residential
– 1 (R1) zone. A detached dwelling is present on the site. Access to the property is via SE May Valley Rd.
The proposed restoration is a corrective action in response to CODE22-000071, which includes the following
unpermitted work:
• Grading;
• Placement of gravel;
• Placement of flagstone pavers;
• Installation of a stairway from the northern, upper portion of the property down to the southern, lower
portion; and
• Installation of two (2) retaining walls: one (1) four-foot (4’) wall at the base of the slope and a three-foot
(3’) tall wall adjacent to May Creek on the south side of the unpermitted work.
Per the SEPA Environmental Checklist (Exhibit 5), approximately 3,307 square feet of area was graded. One
thousand six hundred and fifty-four (1,654) cubic feet of gravel and 1,082 square feet of flagstone pavers were
placed on the north side of May Creek. This does not include the work completed for the stairs which included
regrading and pavers. Amounts were not included related to work to construct the stairs or the retaining walls. All
unpermitted work occurred within the critical area of May Creek.
Restoration work will include removal of the unpermitted improvements, regrading to before the unpermitted

The mitigation plan includes a planting plan, planting specifications and a maintenance and
monitoring plan. Staff has not seen evidence that the activity would conflict with best
management practices.
iii. Impacts are minimized and, where applicable, disturbed areas are immediately restored;
Staff Comment: Disturbance is proposed to occur within a 7,000 square foot area located on the
southern portion of the property. Disturbance would include removal of unpermitted development and
invasive species. Based on the site plan (Exhibit 2) and site photos provided within the mitigation plan,
two (2) chain link fences abut the project area on the eastern and western sides. It appears they have
been placed within the critical area buffer at the property line. The fencing looks to have a green
material draped over it. Removal of this fencing was not included as part of the mitigation plan. As
such, staff recommends as a condition of approval that the applicant provide revised plans at the time
of civil construction permit application showing the removal of the fences along the property lines
within the critical area(s) abutting the area of restoration. The plans shall be reviewed and approved
by the Current Planning Manager prior to civil construction permit issuance.
As part of the restoration mitigation plan, specifications for removal of unpermitted improvements,
installation of plantings and maintenance and monitoring have been included by the qualified
professional. To ensure disturbed areas are restored per the recommendations of the biologist, staff
recommends as a condition of approval that the applicant complete the restoration process per the
guidelines provided within the mitigation plan prepared by Confluence Environmental Company, dated
August 2023, and any future addenda.
The geotechnical documents provide recommendations related to removal of English Ivy on the slope,
erosion control and grade restoration. As such, staff recommends as a condition of approval, the
applicant comply with the recommendations of the Residential Geotechnical Mitigation Report,
prepared by The Concept Group dated June 27, 2023, and any future addenda. The applicant’s
geotechnical engineer shall review the project’s civil plans to verify compliance with the geotechnical
report. The geotechnical engineer shall submit a letter directly to the Current Planning Project
Manager that they have reviewed the construction plans and in their opinion the plans and
specifications meet the intent of the report.
The arborist report identifies that unpermitted work damaged five (5) on-site significant trees. Off-site
trees were within the impacted area; however, it appeared that the majority of impacts were likely
limited to feeder roots which would not impact structural stability of the trees. Based on the arborist’s
experience, trees can take three to five (3-5) years before displaying signs of negative impact from
construction activity. Additionally, it does not appear that the mitigation plan includes monitoring of
the existing trees. As such, staff recommends as a conditional of approval the applicant submit an
updated arborist report at the time of civil construction permit application. The updated arborist report
shall reassess the on-site trees and off-site trees impacted by the unpermitted work. A monitoring plan
shall be included which runs concurrently with the provided maintenance and monitoring plan
provided in the mitigation plan. If it is found that any of the retained trees need to be removed, they
shall be replaced with an equal number of native trees at an equal rate of tree credits to the removed
tree. The plan shall be reviewed and approved by the Current Planning Project Manager prior to civil
construction permit issuance.

As shown on the site plan, the unpermitted work comes as close as within one foot (1’) of the ordinary
high-water mark (OHWM) of May Creek. Provided documents do not indicate whether in-water work
would occur or how restoration work would avoid in-water work. The Construction Mitigation letter
(Exhibit 15) recommends that demolition work should occur in the dry season, such as summer 2024
with restoration (removing invasive species and installation of native vegetation) occurring in fall
2024. Further, the Hazardous Materials Management Statement (Exhibit 16) states that it’s not
expected that construction vehicles would be refueled on-site, but if it does then it would be limited to
driveway areas only and a spill control kit would be on-site. As such, to ensure impacts to May Creek
are minimized, staff recommends as a condition of approval that the applicant provide revised plans
with the civil construction permit application identifying how restoration would avoid in-water work.
If in-water work is deemed unavoidable, the work shall only occur between July 1 and September 30.
All demolition work shall be completed by September 30, 2024. All plantings shall be installed and
inspected for compliance by December 2, 2024. All work shall be completed by hand. No refueling shall
occur on-site. The plans shall be reviewed and approved by the Current Planning Project Manager prior
to civil construction permit issuance.
The unpermitted work occurred within mapped critical areas and their buffers. Staff has seen no
evidence that the critical areas and their buffers have been marked on the site. RMC 4-3-050G3, Native
Growth Protection Areas requires a native growth protection area by instituted to protect critical areas
from any proposed development for a non-exempt activity. This includes protected slopes and their
buffers and Class F streams, such as May Creek. Creating a Native Growth Protection Area on the site
would ensure that impacts to the restoration area, and on-site critical areas in general, would be
minimized. As such, staff recommends as a condition of approval that the applicant establish and
record a permanent and irrevocable easement encompassing the entirety of the area on the property
from the southern property line to the northern most point of restoration (top of slope). The protective
easement shall be held by the current and future property owners, shall run with the land and shall
prohibit development alteration, or disturbance within the easement except for purposes of habitat
enhancement as part of an enhancement project which has received prior approval from the City, and
from any other agency with jurisdiction over such activity. Prior to recording of the easement, the
applicant shall submit draft easement language with the civil construction permit for review and
approval by the Current Planning Project Manager. The easement shall be recorded prior to final
inspection of the civil construction permit. Permanent fencing at the top of the slope shall be installed.
Fencing shall be a wooden two (2) rail split fence with permanent attached wood or metal signs
identifying the purpose of the fencing. Suggested wording is as follows: “Protection of this natural area
is in your care. Alteration or disturbance is prohibited by law.” The applicant shall provide fence and
signage details. The final design shall be reviewed and approved by the Current Planning Project
Manager prior to construction permit approval.
iv. Where water body or buffer disturbance has occurred in accordance with an exemption during
construction or other activities, revegetation with native vegetation shall be required;
Staff Comment: All proposed vegetation to be planted is native species.
v. If a hazardous material, activity, and/or facility that is exempt pursuant to this Section has a significant
or substantial potential to degrade groundwater quality, then the Administrator may require
compliance with the Wellhead Protection Area requirements of this Section otherwise relevant to

that hazardous material, activity, and/or facility. Such determinations will be based upon site and/or
chemical-specific data.
Staff Comment: Not applicable. The proposal does not include a significant or substantial potential to
degrade groundwater quality.
