DEPARTMENT COMMENTS
Outlined below are the comments made by the representatives of each department present at the
preapplication conference. Each section should be read thoroughly. If you have questions, please contact
the representative listed for that section.
PLANNING DIVISION (Matthew Herrera, 253-835-2638, matt.herrera@cityoffederalway.com)
Clearing & Grading Plan Approval — The department has determined that no land use permitting
will be required. The applicable clearing and grading regulations set forth in FWRC 19.120.070 et al
will be reviewed and approved as part of the Public Works Engineering (EN) review process.
2. Tree Removal — Pursuant to 19.120.030(13), the removal of trees in easements and rights -of -way
for the purposes of constructing utilities are exempt from Tree and Vegetation Plan approval and
therefore no code -based mitigation is required. Although exempt, the policy makes clear that
protection of trees shall be a major factor in the location, design, construction, and maintenance of
utilities.
Critical Areas — Administrative approval (if needed) for encroachment into wetland/stream buffer
areas within the Belmor Mobile Home Park will also be a component of the clearing and grading
plan approval. Please submit a final critical areas report with the EN submittal.
4. After Hours Work — Permitted work hours are 7:00am to 8:00pm Monday -Friday and 9:00am to
8:00pm Saturday. Work outside of those hours or on Sundays or holidays observed by the city is not
permitted outright and requires written authorization from the Community and Economic
Development Department. Please submit any after-hours work requests to the department at least
two weeks from the expected start date. Any work near residential areas may require the district to
provide mailed notice to property owners.
PUBLIC WORKS DEVELOPMENT SERVICES DIVISION (Kevin Peterson, 253-835-2734,

Right -of -Way Permits
Current project design proposes work in City Right -of -Way (ROW) in four (4) separate locations —
20'h Avenue South, from South 33& Street to 200'Way South; Crossing South 324" Street; Crossing
South 320'' and extending approximately 170 feet north on 21 ' Avenue South; and 20`h Avenue
South from South 318ffi Place to South 316`h Place. Streets Division staff have determined that all
work in the ROW can be covered under a single ROW Permit. If it is necessary to phase the project
over an extended period of time, then additional ROW Permits may be required. The Streets
13-101848 Doc LD. 63424

Division manager will make the final determination if additional ROW Permits will be required,
based on the estimated timing of project phasing. Kathleen Messinger, Street Systems Engineering
Technician, will be the contact for the ROW Permits. Kathleen's contact info is 253-835-2725, or
kathy. messi nger(ar7.cityoffederalway.com .
2. Open -cutting of City streets will require full -width asphalt overlays. Streets Division will determine
the limits and other requirements of the overlay.
3. City policy is to require that all utility crossings (transverse) are to be pushed or bored. However, the
Streets Division Manager has authorized open cuts for crossing South 324"' Street and South 320''
Street. Details of this authorization can be found in letters dated March 4, 2013, addressed to John
Bowman, LUD General Manager.
4. In conjunction with the asphalt overlay, all ADA ramps that are adjacent to the overlay sections shall
be re -constructed (as necessary) to bring those ramps into compliance with current ADA standards.
5. All traffic calming devices (traffic circles, speed humps, etc.), and channelization markings affected
by the asphalt overlay shall be replaced to city standards.
6. Per City standards, all open cuts within the City ROW require 100% crushed rock backfill.
7. Per City standards, pipes shall be removed, rather than abandoned in place, within City ROW. A
request for variance to this standard may be submitted to the Streets Division Manager.
Temporary traffic control shall be per the current edition of the MUTCD and/or WSDOT Standards.
Engineering (EN) Approval Issues
City Development Services staff will review the temporary erosion and sediment control measures
associated with the project work outside the City ROW (on private property). A separate submittal is
required for the EN Approval process. Three (3) sets of the plans shall accompany the application
for EN.
Erosion control measures, per Appendix D, 2009 KCSWDM, are required.
Provide approximate cut and fill quantities on the plans.
4. Provide a copy of the Construction SWPPP with the EN application.

Re: Lakehaven Utility District Sewer Line Project Delineation Report
The Watershed Company Reference Number: 120804
Dear Adam:
On November 28, 2012 Ecologist Ryan Kahlo and I completed a wetland and stream
delineation study at the storm water detention pond located on the Belmor Golf &
Country Club in the City of Federal Way (parcel number 1621049037). This letter
summarizes the findings of this study and details applicable federal, state, and local
regulations. The following attachments are included:
Wetland and Pond Delineation Figure
Wetland Determination Data Forms
Project Description
The Lakehaven Utility District plans to replace approximately 6,400 linear feet of
existing gravity sanitary sewer pipe located within the City of Federal Way's Downtown
Core area. The existing sewer pipe is under capacity and needs to be upsized to handle
anticipated future flows. Approximately 500 lineal feet of sewer pipe runs through the
Belmor Golf and Country Club in a raised berm that separates two water bodies - an
equalization pond and an upland stream. The new sewer pipe in this area is proposed
to be 27-inch.
The District is evaluating two alignment alternatives for replacement of the new sanitary
sewer main through the golf course (see Wetland and Pond Delineation Figure). The
proposed alignment is to replace the existing pipe in, or near, the current sanitary sewer
alignment, located in the raised berm that separates the pond and the stream. The
alternative alignment is the installation west of the pond in the ninth fairway of the golf
course. The alignment alternatives are shown in the Wetland and Pond Delineation
Figure.

Methods
Public -domain information on the subject property was reviewed for this delineation
study. These sources include USDA Natural Resources Conservation Service Soil maps,
U.S. Fish and Wildlife Service National Wetland Inventory maps, Washington
Department of Fish and Wildlife interactive mapping programs (PHS on the Web and
SalmonScape), King County's GIS mapping website (iMAP), and the City of Federal
Way website.
The study area was evaluated for physical wetland characteristics using methodology
from the Corps of Engineers Wetland Delineation Manual (Manual) (U.S. Army Corps of
Engineers [Corps] 1987) and the Regional Supplement to the Corps of Engineers Wetland
Delineation Manual: Western Mountains, Valleys, and Coast Region Version 2.0 (Regional
Supplement) Corps May 2010). Wetland boundary determinations are based on an
examination of vegetation, soils, and hydrology. Soil, vegetation, and hydrologic
parameters were sampled at several locations to determine wetland presence or absence.
Data points on -site are marked with yellow- and black -striped flags. We recorded data
at two of these locations. Note that not all areas that meet physical wetland
characteristics are necessarily jurisdictional or "legal" wetlands. Therefore, delineated
wetland areas covered under this study were also evaluated for their jurisdictional
status at the local, state and federal regulatory levels.
We also reviewed two documents for background information on the regional
stormwater detention facility:
Geotechnical Data Report: South 32411, to South 336th Trunk Storm Drainage and
Belmor Regional Storage Facility Improvements Project RFB 98-107, Geotechnical Data
Report, CH2M HILL,1998.
Operations and Maintenance Manual: South 32411, to South 33611 Trunk Storm
Drainage and Belmor Regional Storage Facility Improvements Project, Operations and
Maintenance Manual, CH2M HILL, 1999.
Areas meeting wetland parameters were marked with pink- and black -striped flags.
Pond A was marked with 36 flags. The ordinary high water mark (OHWM) of the
stream was flagged with blue- and white -striped flags. Stream A was marked with 31
flags on the right bank and 18 flags on the left bank. We assessed the ecological
functions and values of the pond area using a credit and debit calculating tool from the
Washington State Department of Ecology (Calculating Credits and Debits for Compensatory
Mitigation in Wetlands of Western Washington, Publication #10-06-011).
Delineation Report
Miller, A.
January 24, 2013

Findings
The subject area contains a jurisdictional stream and a constructed detention pond with
wetland characteristics located between a golf fairway and a row of mobile homes along
Augusta National Lane.
Stream A
The stream emerges from an 82-inch concrete culvert west of Augusta National Lane
and Pebble Beach Circuit (see Figure 1). The culvert carries stormwater from a highly -
urbanized basin to the north that contains the Commons Mall, roads, and other
commercial activities. Stream A flows south in the subject area for approximately 440
feet, then drains to a concrete control and pump station, then into another culvert that
carries the flow beneath The Dunes Court and eventually off -site. Stream A is a
perennial watercourse that does not support migratory fish due to several blockages
downstream. It does, however, flow to Hylebos Creek, which supports Coho and Fall
Chinook, according to SalmonScape (SalmonScape website, data downloaded 12/2012).
Figure 1. Left: Photo looking north showing the 82-inch concrete culvert where Stream A enters the
subject area. Right: Photo looking south showing the outflow of Stream A and control station to which
Stream A and Pond A drain.
Federal Way classifies streams as "Major' or "Minor" according to FWRC section
15.05.030 - Additional definitions. A "'Major Stream' means any stream, and the
tributaries to any stream, which contains or supports, or under normal circumstances
contains or supports, resident or migratory fish." Stream A is a tributary to a salmon -
bearing stream, thus is a "Major Stream".
Delineation Report
Miller, A.
January 24, 2013

Pond A
The storm water detention pond, called the Belmor Regional Storm Water Storage
Facility (from here on called the Belmor RSF), is "...an off -channel excavated basin
hydraulically interconnected to the existing stream channel aligned through the Belmor
golf course (along 9th/18th fairway)" (Operations and Maintenance Manual, CH2M HILL,
1999). It is separated from Stream A by a maintenance access road that acts as a berm.
Two sets of culverts provide hydrologic connectivity between Stream A and the Belmore
RSF. The pond was built in 1998 to replace and enhance the storm water attenuation
functions of the old storm water detention pond on the Commons Mall property to the
north (Geotechnical Data Report, CH2M HILL, 1998). The Belmor RSF was designed as a
component of a larger drainage improvement project in the West Branch Hylebos Creek
Sub basin (City of Federal Way website, data downloaded 12/2012).
The reservoir operates at two levels depending on the time of year (Operations and
Maintenance Manual, CH2M HILL, 1999). Between October 1 and May 1, the level is
reduced to a minimum operating level to increase live storage during the rainy season.
Minimum level is achieved by opening a 24-inch sluice gate at the minimum elevation in
the concrete control station at the south end of the Belmore RSF. The sluice gate is
closed in the summer to raise the level of the water to a 30-inch upper opening with a
bottom elevation that is 4 feet higher than the bottom of the sluice gate. Two spillways
are situated above the second opening to accommodate storm events: the highest, an
emergency spillway 10 feet higher than the lowest 24-inch opening, gives the pond 10
feet of live storage capacity (Operations and Maintenance Manual, CH2M HILL, 1999). The
Belmor RSF is currently functioning as intended.
Figure 2. Left: Photo facing north of the berm/ maintenance access road. The pond is located to the left
and the stream to the right. Right: Photo facing southwest showing the parallel culverts and north
detention pond area.
The two sets of culverts that provide hydrologic connection between Stream A and the
Belmor RSF are eight feet above the minimum pond elevation (Operations and
Delineation Report
Miller, A.
January 24, 2013
Page 5
Maintenance Manual, CH2M HILL,1999). A small amount of water from the stream was
flowing into the pond at the time of our visit which was being maintained at the
minimum elevation.
The seasonally ponded area exhibits wetland characteristics. Rooting zone soil is a
yellowish gray (2.5Y 4/1) gravelly sandy clay loam with dark yellowish brown (10YR
4/6) redoximorphic features. Red alder (Alnus rubra, FAC), reed canarygrass (Phalaris
arundinacea, FACW), soft rush Uuncus effusus, FACW), and small -fruited bull rush
(Scirpus microcarpus, OBL) dominate the area in the sampling area. The water table was
noted within 6 inches of the surface in the soil pit.
Conditions near Pond A
The area near Pond A is characterized by mowed lawn and some scrub shrub vegetation
dominated by red -osier dogwood (Cornus sericea, FACW), and young Douglas -fir
(Pseudostuga menziesii, FACU) and red alder trees. The soil sampled near the pond was
not saturated at the time of our visit after heavy rain events had moved through the
area.
Local Regulations
Pond A
Pond A may not be regulated as a wetland by the City of Federal Way despite meeting
physical wetland criteria. Per section 19.175.010(3) of the Federal Way Revised Code
(FWRC) "Surface water ponds, drainage ditches, and other such facilities which were
designed to impound or convey water for an engineered purpose are not considered
regulated wetlands under this division provided they meet all of the following criteria:"
(a) The drainage facility must have been intentionally human -created. This is to
differentiate from those wetland sites that are accidental consequences of
development actions, such as road construction or culvert placement. Such sites
may be considered regulated wetlands by the director upon a review, under
subsection (2)(g) of this section, of the ecological functions and values of the site.
(b) The drainage facility must have been originally constructed on uplands
(nonwetland areas). If the drainage facility is located within a straightened,
channelized, or otherwise disturbed natural watercourse, it may be considered a
regulated wetland by the director upon a review, under subsection (2)(g) of this
section, of the ecological functions and values of the site.
(c) The facility must be actively operated as a surface water drainage facility.
Abandoned drainage facilities may be considered regulated wetlands by the
director upon a review, under subsection (2)(g) of this section, of the ecological
functions and values of the site.
Delineation Report
Miller, A.
January 24, 2013
Page 6
(d) Wetland conditions have not expanded beyond the originally constructed
drainage facility boundary. In such a case, the expanded area may be considered
a regulated wetland by the director upon review, under subsection (2)(g) of this
section, of the ecological functions and values of the site.
(e) The drainage facility was not designed or constructed as a requirement to
mitigate previous wetland impacts.
(f) The director finds that limited ecological functions and values do not warrant
application of the city's wetland regulations.
The pond meets criteria (a), (c), (d) and (e). With regards to criterion (b), historic aerial
photographs from 1998 and 1990 (King County iMap) show that Pond A was excavated
from lawn within the golf course. However, it is unclear from the photography whether
wetland features were present in the lawn before construction. Peizometer data from
the 1998 CH2M HILL study, taken from the pond location, provides additional
evidence. A water table "...from approximately 5 to 9 feet below the ground surface..."
(pp. 5-2) was observed in a well in the project area, showing the water table was well
below the rooting zone and therefore not shallow enough to satisfy wetland hydrology
criteria. Furthermore, the study found the Alderwood soil, "...which underlies most of
the project alignment..." to be very dark brown (10YR 2/2) to dark brown (10YR 3/3) to a
depth of 27 inches, colors that are consistent with non -wetland soils. The report data
and the photographic evidence show the pond was built from non wetland, thus
subsection (b) is met.
Criterion (f) requires a decision of the director based on an assessment of "ecological
functions and values". We evaluated the functions of the Belmor RSF using the Ecology
Credit and Debit tool. As expected, the pond rates moderate to high for hydrologic
function (as it was engineered specifically for flood flow attenuation). However, water
quality improvement function is moderate due to the lack of substantial vegetation in
the ponded areas. The habitat function is low due to the lack of structural features (e.g.,
large woody debris, snags, etc.), developed vegetation structures, and lack of
connections to undisturbed habitat areas nearby. The functional level of the Belmor RSF
would likely be consistent with other engineered storm water detention facilities in the
area. Based on our evaluation of this pond using Ecology guidance, the strict
application of FWRC wetland regulations are not justified.
Stream A
Per chapter 19.165.010 of the FWRC, Stream A requires a 100-foot buffer extending
horizontally in all directions from the OHWM. Public utilities may be constructed
within a stream setback pursuant to requirements in the FWRC, Chapter 19. Table 1,
below, summarizes the conditions under which public utilities may be routed through a
stream setback.

State and Federal Regulations
Wetlands are regulated by the U.S. Army Corps of Engineers (Corps) under section 404
of the Clean Water Act. Artificially created features such as ditches and storm water
detention ponds that drain to Waters of the State may also be regulated by the Corps.
Any filling of Waters of the State, including wetlands (except isolated wetlands) and
some upland ditches or ponds that exhibit wetland characteristics and that are found to
be non -isolated, would require notification and permits from the Corps. Pond A would
be regulated by the Corps. Federally permitted actions that could affect endangered
species (i.e. salmon or bull trout) may also require a biological assessment study and
consultation with the U.S. Fish and Wildlife Service and/or the National Marine
Fisheries Service. Application for Corps permits may also require an individual 401
Water Quality Certification and Coastal Zone Management Consistency determination
from Ecology.
In general, neither the Corps nor Ecology regulates wetland or stream buffers, unless
direct impacts are proposed. When direct impacts are proposed, mitigated wetlands
may be required to employ buffers based on Corps and Ecology joint regulatory
guidance.
Delineation Report

Summary
Both possible sewer replacement alignments will include construction within the 100-
foot buffer extending from Stream A. Construction of the proposed alignment is all
within this buffer and the alternative alignment includes some construction within the
buffer. Therefore, construction of the new sewer will have to be in conformance with
City of Federal Way local regulations for construction within a stream buffer. If any
construction is proposed within Pond A it will need to be in conformance with the State
and Federal regulations listed in the report.
The information contained in this letter or report is based on the application of technical
guidelines currently accepted as the best available science and in conjunction with the
manuals and criteria outlined in the methods section. All discussions, conclusions and
recommendations reflect the best professional judgment of the author(s) and are based
upon information available to us at the time the study was conducted. All work was
completed within the constraints of budget, scope, property access, and timing. The
findings of this report are subject to verification and agreement by the appropriate local,
State and Federal regulatory authorities. No other warranty, expressed or implied, is
made.
Please call if you have any questions or if we can provide you with any additional
information.
Sincerely,
?d, k-

SPACING ARE USED, THE MIRE MESH SUPPORT FENCE MAY BE ELIMINATED.
IN SUCH A CASE. THE FILTER FABRIC IS STAPLED OR WIRED DIRECTLY TO
THE POSTS WW1TH ALL OTHER PROVISIONS OF FILTER FENCE NOTE 5
APPLYING. EXTRA CARE SHOULD BE USED WHEN JOINING OR OVERLAPPING
THESE STIFFER FABRICS
7. THE CITY SPECIFIES THE USE OF PROPERLY COMPACTED NATIVE MATERIAL
IN MANY INSTANCES, THIS MAY BE THE PREFERRED ALTERNATIVE BECAUSE
THE SOIL FORMS A MORE CONTINUOUS CONTACT WITH THE TRENCH BELOW.
AND USE OF NATIVE MATERIALS CUTS DOWN ON THE NUMBER OF TRIPS
THAT MUST BE MADE ON AND OFF -SITE IF GRAVEL IS USED INSTEAD, THE
TRENCH SHALL BE BACKFIU D WITH 3/4-INCH MINIMUM DIAMETER WASHED
GRAVEL CARE MUST BE TAKEN WHEN USING GRAVEL TO ENSURE GOOD
CONTACT BETWEEN THE FABRIC AND THE TRENCH BOTTOM TO PREVENT
UNDERCUTTING.
B. FILTER FABRIC FENCES SHALL BE REMOVED WHEN THEY HAVE SERVED THEIR
USEFUL PURPOSE, BUT NOY BEFORE THE UPSLOPE AREA HAS BEEN
PERMANENTLY STABILIZED, RETAINED SEDIMENT MUST BE REMOVED AND
PROPERLY DISPOSED OF, OR MULCHED AND SEEDED.
1. INSPECT IMMEDIATELY AFTER EACH RAINFALL. AND AT LEAST DAILY DURING
PROLONGED RAINFALL REPAIR AS NECESSARY.
2. SEDIMENT MUST BE REMOVED WHEN IT REACHES APPROXIMATELY ONE THIRD
THE HEGHT OF THE FENCE, ESPECIALLY IF HEAVY RAINS ARE EXPECTED.
3. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE FILTER FENCE IS
NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM WITH THE EXISTING
GRADE, PREPARED AND SEEDED.
4. ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHAH BE
REMOVED WITHIN 3D DAYS AFTER FINAL SITE STABILIZATION IS ACHIEVED OR
AFTER THE TEMPORARY 'BEST MANAGEMENT PRACTICES" ARE NO LONGER
