RE. Permit No. 10-101600-00-SM; Retreat Meadows Street Modification - 35615 3rd Ave SW
Dear Mr. LaBrie,
This letter responds to your request to modify and/or waive required street design standards in regard
to the above -referenced project. After evaluating your request, review of Federal Way Code
provisions, and direction provided by the City Council, the Public Works Department addresses your
requests as follows:
Block Perimeter Standards for non -motorized access (including bikeways and walkways):
The Public Works Department hereby agrees to modify this standard as detailed in your
request, and allow the block, created by Roads A, B, C, and D (as shown on the April 20,
2010 drawings), to exceed the City's block perimeter standard of 1,320 feet to approximately
1,500 feet.
Second access for a subdivision of 25 or more lots:
The Public Works Department hereby denies your request for a single access to the
subdivision. Based on the anticipated number of average vehicular trips per day generated by
the development, a second access will provide a benefit to the neighborhood.
No street or combination of streets shall function as a cul-de-sac longer than 600 feet:
The second access to the subdivision is required; consequently, the street systems will not
function as a cul-de-sac or dead end street.
Additionally, the Public Works Department has the following comments on the April 20, 2010 plan
submittal:
Streets:
1) Extension of Road B, west of Road A — This roadway extension shall be located further
south in order to accommodate the future roadway extension beyond Retreat Meadows.
Currently this alignment ends at a developed lot. A southerly shift will allow access to
the undeveloped portions of the parcels to the west. Please keep in mind that the
remainder of Road B (east of Road A), shall align with this extension, and not create an
off -set intersection.

2) Road A connection to SW 3561h Street — This roadway shall be constructed to its full -
width, per City Standard 3-2S.
3) Show the proposed future connection of the Lifeway Church access road to Road A.
4) Road E — City Standard 3-2Y cannot exceed 150-feet in length, and shall be located
within a private tract. Verify Fire Department (South King Fire and Rescue)
requirements for turnarounds and/or sprinkler systems.
Storm Drainage:
Public Works will not approve this revision for the following reasons:
1) The project does not provide adequate on -site flow control facilities for each drainage
basin. The project site (existing) is divided into three separate threshold discharge areas,
as defined in the 1998 King County Surface Water Design Manual. The narrative in the
TIR (page 4-1) suggests that two of these three threshold discharge areas (basins A and
C) reconnect within '/4 mile downstream of the site. However, the Overall Drainage
Basin Map (located in the back pocket of the TIR), which shows the off -site flow paths,
indicates that Basins A and C flow paths do not reconnect within'/4 mile downstream, but
rather on the order of % of a mile downstream of the site. This is well beyond what the
City would consider to be an allowable tolerance to allow combining the on -site flow
control facility into a single pond, and therefore we cannot support the current single
pond concept.
2) Further Technical Review comments will be forwarded under cover of the preliminary
plat process (City File No. 08-101729-00-SU).
If you have any question regarding the above comments, please contact Kevin Peterson, Engineering
Plans Reviewer, at (253) 835-2734.

There is no minimum centerline radius on local streets. Traffic calming devices may be incorporated
into streets in residential zones, as approved by the public works director.
Cross-section type Y may be used in cluster and short subdivisions when all of the following conditions
are met:
(1) The street is in a private tract.
1 (2) The tract abuts four or less dwelling units.

Retreat Meadows Preliminary Plat
Dear Mr. Herrera:

Job No. 1453-001-007
With this letter and enclosed exhibit, ESM is formally requesting a Road Modification for
the Preliminary Plat of the Retreat Meadows.
We understand that this project is vested to the prior version of the FWMC; therefore, all
code citations will reflect the old numbering system, which differs from the newly adopted
Federal Way Revised Code. Specifically, the code citations in this letter refer to the Public
Works Development Standards, Chapter 3, dated February 2005.
The redesigned preliminary plat of Retreat Meadows meets all of the required road design
standards except the following:
1.3.2 Streets
C. Alignment and Location.
4. Block perimeters should be no longer than 1,320 feet for non -motorized
access and 2,630 feet for streets.
The proposed perimeter distance for the internal block bound by proposed Roads A, B, C
and D is 1,720 feet, as measured along the centerlines. The true "perimeter" of this block
is 1,483 feet when measured along the right-of-way, and even shorter when measured
along the actual sidewalk..
Providing an internal non -motorized connection between Roads A and D does not appear
to provide any benefit to the layout or non -motorized circulation within this development
as it would only shorten the walking route for a very few, select lots. We believe that this
requirement was adopted to break up long blocks and that the unique Wnfigklr� �o
this property and the proposed development is not conducive to a 1.320-toot mgxVi
rm D
length for non -motorized access.

This request meets the standards for granting a modification because a mid -block, non -
motorized connection would not be advantageous to the neighborhood or city as a whole.
5. More than one connection to the existing public street system will be
provided for any development, or part thereof, of four acres or more, or
generating more than 250 trips per day or more (25 single-family lots). If not
otherwise infeasible, each connection will be to a different street
Since this project is only bound by one public street (SW 356th Street) and the length of
frontage is only approximately 326 feet, two connections are not practical to this arterial
roadway.
This project is proposing to stub public roads to the east, west and southern boundaries
in order to provide future connections to, and expansion of the public street system as
perimeter properties develop in the future.
Expansion of the existing private road along the western property boundary (3`d Ave. SW)
was previously analyzed to provide a second connection to SW 356th Street; however, the
intersection of Sd Ave SW and SW 3561h Street occurs on the inside of the horizontal curve
and would require dedication of private property from adjacent landowners, which is
outside the control of the applicant Furthermore, expansion of 3"d Ave. SW could cause
turning conflicts with traffic from 41h Ave. SW and 2n" Ave. SW, both of which are within 335
feet of this intersection. There are also other improvements (a rock wall and vegetation)
that hinder the existing sight distance at this intersection.
This request meets the standards for granting a modification because a second
connection to the existing public street system would not function as safely as combining
the access points to align with the existing intersection of 2nd Ave SW.
G. Cul-de-sacs and Dead-end Streets. No street or combination of streets shall
function as a cul-de-sac longer than 600 feet.
The cul-de-sac nature of this project is a temporary condition and will be relieved when
adjacent properties develop. In order to provide for future connectivity and expansion of a
grid -style road network in this area, this project is stubbing public roads to its east, west
and southern boundaries.
Phase 1 will provide for three separate "hammer -head" style turnarounds at the
intersections of Road A with Roads E, B and C. During Phase 2, an internal loop will be
created providing greater turn -around and circulation options, and a continued roadway
stub to the east
This request meets the standards for granting a modification because the unusual
configuration of the property and lack of adjacent right-of-way preclude the construction of
a secondary access.

1.3.4 Bikeways and Walkways
C. Pedestrian and bicycle access shall be provided to develop a non -motorized
network with a block perimeter of no greater than 1,320 feet, as measured on the
centerlines. This requirement may be modified if connections cannot be made due
to:
1. Topographic constraints
2. Environmentally sensitive areas
3. Adjacent development not being conducive.
Please see the justification above provided for Section 1.2.3 Streets, as to why the site plan
and adjacent development are not conducive to this requirement
If you have any additional comments or questions regarding this modification request,
please contact me immediately. In the meantime, thank you for your attention to this
request and we look forward to moving toward a hearing in the near future.

RE: Retreat Meadows Subdivision - File No. 08-101729-00-SU
Dear Mr. Miller:
This letter is a right-of-way improvement modification request for improvements at the
proposed Retreat Meadows subdivision, just off of SW 356t" Street and 2nd Ave. SW.
This modification request comes out of the traffic section within the August 8, 2008 letter
from Matthew Herrera and Sarady Long to ESM Consulting Engineers.
The following items are part of this modification request:
Under item #1 of the Traffic Section, we request a modification from any improvements to
-SW 356t" St. from the existing road section to the Type "C" road section. The existing SW
��"
356t"St. road has been improved over recent years to include four travel lanes and a
middle turning lane, curb, gutter and sidewalks. The existing street functions safety and
n adequately for the neighborhood and the city as a whole and does not need
4 improvements at this time or in the near future. The requirement for 11 feet of right-of-way
l� dedication is not being opposed.
Under item #2 of the Traffic Section, 2nd Ave. SW between SW 358t" St. and SW 350" St is
proposed be constructed as a half street improvement of a Type "W" street. This would
include 24' paved street with vertical curb, 4' planter strip with street trees, 5' sidewalk, and
I streetlights. Ten feet of these improvements would be built on an access, utility easement
Qwithin the Lifeway Church property. This easement would be recorded prior to preliminary
plat approval. This same half street improvement and 10' easement is proposed for SW
lb 358t" Street between 2nd Ave. SW and the easterly property line.
Under item #3 of the same Traffic Section, the section of the proposed SW 358t" St.
between 2nd and 3`d has been called out as "W" street section. Since this section of 358th
will not be extended west dues to existing homes in the area, this wide road section is
^ not warranted. A request to modify this road section is proposed. Instead of a 52 foot
i� right-of-way, 28 feet of roadway, curb, gutter and sidewalks and a 3 foot utility strip the
following is proposed; a 40 foot right-of-way, 24 feet of roadway, curb, gutter, sidewalk and
a 3 foot utility strip is proposed. This smaller road section is similar to other streets in the
area and will help with traffic calming requested under item #6 in this letter.

Also under item#3, a temporary turn around at the easterly portion of SW 358th St. is
required. A modification to the standard hammerhead is requested. The request is to
offset the temporary hammerhead from the centerline of the 24' paved street north 28 feet
(to stay within the future right-of-way) and south 62 feet into the 23' wide pedestrian
corridor. The overall length of the hammerhead will meet the minimum required 90'. The
south radius would meet the 28' min., but the north radius would be 16.0'.

Retreat Meadows - 356153rd Ave SW
Response to Right -of -Way Modif►cation Request
Dear Mr. Scheuerman,
This letter responds to your August 19, 2008 request to modify the City's Standard roadway
sections associated with the proposed plat of Retreat Meadows.
After evaluating your request, review of Federal Way City Code (FWCC) provisions (Section 22-
1477, 22-1496), and direction provided by the Public Works Director, each of your specific
requests to modify the roadway sections for this project are addressed below, with the City's
response following each:
Requesting waiver of the required street improvements associated with SW 356d'
Street, and agreeing to dedicate right-of-way along SW 3560 Street, adjacent to
the project:
The City hereby waives the construction of required street improvements, with
the additional 11-feet of right-of-way to be dedicated to the City at final plat
recording.
Request to place the east 10-feet of the 27d Avenue SW improvements (north of
SW 3560 Street) and the north 10-feet of the SW 358`" Street improvements
(east of 27d Avenue SW) within 10-foot easements on the adjacent Lifeway
Church property, rather than dedicate the entire width as right-of-way.
(Applicant is agreeing to construct the required half -.street improvements along
these roadway sections )
The City hereby denies this request per the requirements of FWCC Section 20-
180(a), which states that'Streets within an approved land division shall be within
a dedicated public right-of-way.' The entire half -street improvements must be
within right-of-way, and shall be dedicated to the City at final plat recording. For
the record, the required half street improvements for the segments of roadway
identified above shall be as follows: 24-foot paved roadway with vertical curb

and gutter, 4-foot planter strip with street trees, 5-foot sidewalk, and 3-foot
utility strip with street lights. Future development on the adjacent parcel to the
north and east of the plat will require 2'd Avenue SW and SW 358th Street to be
developed to a City Standard Type `S' street section, rather than a Type 'W', if
future traffic warrants the expanded section. However, the expanded street
section would only affect the future development and does not affect this project
since it is constructing 24-feet of paved roadway.
Requesting modification of SW 35e Street between 3`d Avenue SW and 2'd
Avenue SW from a City Standard Type 'W street to a 24-foot roadway with
sidewalks on both sides adjacent to the roadway (no planter strip), and 3-foot
utility strips, all within a 40-foot right-of-way.
The City hereby denies this request per the requirements of FWCC Section 20-
180(b), which states that 'All streets within the public rights -of -way shall be
improved to the standards as specified in FWCC 22-1471 et seq., regarding
required improvements to rights -of -way.' The roadway section that you are
requesting does not meet adopted City standards. This section of roadway shall
be constructed to meet the requirements of City Standard Street Section Type
AW,
Requesting modification of the required turnaround at the east end of the
pmposed SW 35e Street.
The City, with input from the South King Fire and Rescue Fire Marshal, hereby
denies your proposed layout for a modified fire apparatus turnaround
(hammerhead). A hammerhead turnaround can be approved if it meets the
dimensions as depicted in current City Standards (Standard Detail 3-46).
Additionally, per the Fire Marshal, any new homes on those lots that abut that
roadway (currently lots 53-56) shall be sprinkled, should a standard
hammerhead be approved and constructed.
Furthermore, your requests for modifications do not meet any of the criteria
identified under FWCC Section 22-1477: "Modifications, deferments and waivers
The Public Works Director may modify, defer or waive the requirements of this
article only after consideration of a written request for the following reasons
(1) The improvement as required would not be harmonious with existing street
improvements, would not function properly or safely or would not be
advantageous to the neighborhood or city as a whole.
(2) Unusual topographic or physical conditions preclude the construction of the
improvements as required.

(3) Proper vertical or horizontal alignments cannot be determined because the
existing streets do not have correct alignments
(4) The required improvement is part of a larger project that has been scheduled
for construction in the Cdy's adopted Six -Year Transportation Improvement
Program.
In addition, Public Works staff determined that the proximity of the proposed
dual access points at SW 356th Street and 3rd Avenue SW (existing private access
road just west of the proposed 3rd Avenue SW) presents a safety issue that shall
be addressed by combining the existing private driveway with the new 3rd
Avenue SW roadway. This access management issue shall be addressed and a
proposal presented to the Public Works Department for review and approval,
prior to preliminary plat approval.
The conditions of this Right -of -Way Modification will be applicable for a period of one year from
the date of this letter. If a permit for this project is not issued within the one-year time limit,
this waiver will be void and a new request for modification must be submitted.
If you have any questions, please contact Kevin Peterson at (253) 835-2734, or via e-mail at
