LUA22-000230
I have reviewed the application for the Palermo Short Plat located at parcel 6198400340 and have the
following comments:
EXISTING CONDITIONS
The site is comprised of an existing parcel (6198400340), is approximately 44,866 square feet in size and
is generally rectangular in shape. The site currently is vacant without any structures. The site is fronted
by 120th Ave SE to the east, SE 192nd St to the south (City of Kent) and private property on all other sides.
WATER: The proposed development is within Soos Creek Water and Sewer District water service area.
SEWER: The proposed development is within Soos Creek Water and Sewer District sewer service area.
STORM: The site is generally sloped from the northeast to the southwest. There is an existing 18-inch
public stormwater main on the west side of 120th Ave SE (no record drawing available). There is
an existing roadside ditch alon the west side of 120th Ave SE (no record drawing available). They
City of Kent may have existing facilities within SE 192nd St. There is no existing on site stormwater
conveyance system.
STREETS: The proposed project fronts 120th Ave SE along the east property line. 120th Ave SE is classified
as a Residential Access street. Existing Right-of-Way (ROW) width, according to the King County
Assessor Map, is 60 feet. This portion of 120th Ave SE is unimproved with an existing paved road
of approximately 26 feet, 13 feet from ROW centerline, and vegetation at the back of pavement.
The proposed project fronts SE 192nd St along the south property line. The existing property line
serves as the City limits between Renton and Kent. As such SE 192nd St is within the City of Kent’s
ROW. All other property lines abut private property.

STORM DRAINAGE COMMENTS
1. A geotechnical report dated October 21, 2021, completed by Robinson-Noble, was provided with
the Land Use Application. The report discusses the soil and groundwater characteristics of the site
and provides recommendations for project design and construction. Geotechnical
recommendations presented in this report support the use of permeable pavement as the only
viable infiltration style BMP due shallow groundwater observed approximately 2 feet below
ground surface.
2. Daley-Morrow-Poblete Inc., with the Land Use Application, submitted a Preliminary Drainage Plan
and Technical Information Report (TIR), dated March 13, 2023. Based on the City of Renton’s flow
control map, the site falls within the Flow Control Duration Standard- Matching Forested and is
within the Soos Creek Drainage Basin. The report is based on a Full drainage review and Core
Requirements 1 thru 9 and the six Special Requirements have been discussed in the Technical
Information Report.
a. Offsite Analysis, RSWDM Core Requirement #2: All proposed projects must submit an
offsite analysis report that assesses potential offsite drainage and water quality impacts
associated with development of the project site. The preliminary TIR submittal includes a
Level 1 Downstream Analysis that does not identify any downstream drainage problems.
b. Flow Control, RSWDM Core Requirement #3: Any proposed detention and/or water
quality vault shall be designed in accordance with the RSWDM that is current at the time
of civil construction permit application. The project proposes to use an R-tank for the
detention facility which is conceptually acceptable.
c. Conveyance, RSWDM Core Requirement #4: All new conveyance systems constructed as
part of the project must be sized to RSWDM standards for the total tributary area (onsite
and offsite) that the storm systems serve. The preliminary TIR indicates that an analysis
will be added.
i. A conveyance capacity analysis shall be included with the TIR submit as part of
the civil construction permit.

d. Construction Stormwater Pollution Prevention, Core Requirement #5: The proposal does
not include a CSWPP and ESC plan. The preliminary TIR states that these plans and reports
will be added.
i. A CSWPP and ESC plan shall be included with the TIR and utility plans submit as
part of the civil construction permit.
e. Maintenance and Operations, Core Requirement #6: The proposal includes a preliminary
maintenance and operation manual.
f. Financial Guarantees and Liability, Core Requirement #7: All persons constructing any
surface water facilities (including flow control/water quality, conveyance systems,
erosion control and road drainage) are to post with the City a surety device. The amount
of the surety is calculated using the City’s bond quantity worksheet. The preliminary TIR
indicates that this will be provided if required.
i. A Bond Quantity Worksheet shall be submit as part of the civil construction
permit.
g. Water Quality, RSWDM Core Requirement #8: All projects that add more than 5,000
square feet of pollution generating impervious surface (PGIS) that is not fully dispersed
and less than 0.75 acre of pollution generating pervious surface that is not fully dispersed
require water quality. The TIR indicates that the project is adding less than 5,000 SF of
PGIS and is exempt.
i. The project exceeds the 5,000 SF threshold, however, if a leechable metals
covenant is provided for the individual lot rooftops, then the rooftops will not
be counted as PGIS and the project would be exempt. The TIR submit with the
civil construction permit shall include a draft copy of the covenant.
h. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be required
to help mitigate the new runoff created by this development. The proposal discusses the
feasibility of each BMP as listed in section 1.2.9.2.1 Small Lot BMP requirements.
i. Each BMP feasibility shall be explicitly assessed with specific infeasibility criteria
cited where not feasible.
2. A construction Storm Water General Permit from the Department of Ecology will be required as
clearing and grading of the site is shown to exceed one acre.
3. There is a 2023 system Development Charge of $2,300 per new single family residence. SDC fees
are payable at construction permit issuance.
TRANSPORTATION/STREET COMMENTS
1. Frontage improvements are required for all new construction with valuation in excess of

Residential Access street is 53-feet that includes a 26-foot paved road (13 feet from
centerline), a 0.5-foot curb, an 8-foot planting strip, a 5-foot sidewalk, street trees and
storm drainage improvements. No dedication is anticipated.
i. The preliminary plans show the minimum Residential Access street section with
the curbline shown to be 17 feet from the property line. however, there is an
established curbline fronting the parcel immediately to the north which is set 14
feet from the property line (per record project file TED04045). The existing
