Re: Letter of Concurrence
I-405 Wells & Parks Task Force
Dear Mr. Zimmerman:
The City of Renton and the Washington State Department of Transportation (WSDOT) are
working together to move the I-405 projects forward in Renton. WSDOT understands that the
City's groundwater wells are a vital source of water and that the City's parks, trails, open spaces,
and recreation facilities are valuable assets essential to quality of life for Renton's citizens.
A focused effort and cooperation between our two agencies is required to work out the I-405
design challenges in the vicinity of the City's water supply system, Liberty Park, Cedar River Park,
and the Narco property. Consequently, the City and WSDOT formed a Wells & Parks Task Force
in 2004 to address these complicated issues, The Task Force was able to successfully resolve some
of the key issues, but other issues need more evaluation. This concurrence letter documents the
Task Force's objectives, accomplishments to date, and - in the attached Findings Report -
outstanding issues, future steps, and decisions.
Task Force Objectives
The Task Force's primary objective was to identify a proposed alignment for the northbound I-405
to SR 169 off -ramp that:
1. Avoids and/or minimizes impacts to the City of Renton's drinking groundwater supply — well
heads, pump stations, water treatment facilities, and associated utilities;
2. Ensures adequate and safe access:
a. For the City's maintenance personnel to operate and maintain the drinking water wells,
pump stations, water treatment facilities, and associated utilities; and
b. For the public to the City's public park land and facilities; and
c. For emergency response vehicles to the City's water wells and their associated
facilities and park land and their associated facilities; and
d. For the City's maintenance personnel to operate and maintain the City's parks, trails,
building facilities and open space areas; and
Avoids and/or minimizes impacts to public park land and park facilities and is safe for park
users.
Accomplishments
An important accomplishment for the Task Force was identification of the northbound I-405 to SR
169 ramp alignment. The Task Force recommended a northbound I-405 to SR 169 ramp alignment
to the Executive/Administrators Committee as Recommendation #1, understanding that resolution

of wells/park access and impacts will be further addressed. The Executive/Administrators
Committee agreed with this alignment on July 23, 2004. The ramp alignment:
• Avoids the footprint of the existing City well buildings (RW -1, 2, and 3, PW -8 and 9, EW -
3) and the existing water treatment facilities (the corrosion control and treatment facility
(CCTF) and the fluoridation facility).
• Strives to minimize impacts to Cedar River Park and amenities. The ramp alignment
requires an approximate 25 -foot swath along the west side of the Cedar River Park multi-
use ballfield/soccer field and the Renton Community Center, placing the ramp within 65
feet of the Community Center.
The selected ramp alignment will be further examined in the South Renton Implementation Plan
NEPA document and final Section 4(f) determination.
Wells & Parks Task Force Findings Report. Determining the northbound I-405 to SR 169 ramp
alignment was critical for more in-depth discussion about other aspects of this project. With the
specific alignment information we will be able to more effectively analyze other issues, such as the
location of potential public access to and from Cedar River and Liberty Parks, Narco property, trail
connectivity, internal park circulation and access points for maintenance vehicles for Wells 8 and S
and the treatment facilities, as well as underground utility issues. These afore -mentioned issues and
other issues are complex and will need further evaluation. The access and unresolved issues are
documented in the attached Wells & Parks Task Force Findings Report.
Moving Forward
South Renton Implementation Plan Project. The Task Force work done to date has been under
the umbrella of the I-405 North Renton project, now known as the Renton to Bellevue project..
WSDOT has moved project elements south of the SR 169 interchange (including work in the wells
and parks vicinity) to the South Renton Implementation Plan project. The improvements made
south of the SR 169 interchange are more appropriately connected to improvements made through
the Renton "S" curves, and they can be designed and implemented independent of the Renton to
Bellevue project improvements north of the SR 169 interchange. Therefore, it is appropriate to
move project elements south of the SR 169 interchange to the South Renton Implementation Plan
project, allowing WSDOT to construct improvements south of SR 169 only once — avoiding costly
and disruptive rework.
The Wells & Parks Task Force Findings Report will be the basis for continued work and problem
solving in the South Renton Implementation Plan project. Starting immediately, WSDOT will
closely work with City staff to revisit and solve the issues as the 15% design is developed. The
15% design will identify recommended solutions to be evaluated in the South Renton
Implementation Plan NEPA document and final Section 4(f) determination. This work needs to be
completed prior to January 2006 so that WSDOT can begin the NEPA process on/before January
2006. This aggressive schedule is driven by the 2005 Legislative intent to complete the SR 515
(Talbot) interchange in 2010.
The City provided EA scoping comments (October 23, 2003, letter) for the North Renton project.
WSDOT will move the Wells & Parks -related scoping comments to the South Renton
Implementation Plan NEPA scoping document so that they can be appropriately addressed.
Parks Master Plan. The City will be preparing a Parks Master Plan for Cedar River Park, Liberty
Park, and the Narco property commencing in 2005 with an estimated completion date of March

Parks Master Plan. The City will be preparing a Parks Master Plan for Cedar River Park, Liberty
Park, and the Narco property commencing in 2005 with an estimated completion date of March
2006. WSDOT evaluated the City parks at a corridor level in the I405 Corridor EIS and resulting
Selected Alternative in the I-405 Corridor Record of Decision. The I-405 corridor -level final
Preliminary Section 4(f) determination recognized the potential effects on the parks, stating park
areas may be permanently incorporated into the transportation facility. WSDOT recognizes the
importance of parks to the City and is obligated to evaluate park impacts though the NEPA and
Section 4(f) decision-making processes. The City and WSDOT will continue to work together as a
team to explore new solutions and to coordinate plans and designs for the area.
Concurrence
The I-405 South Renton Implementation Plan NEPA document is scheduled to begin on or before
January 2006. Realizing the complexity of the issues at hand, it is advantageous for both parties to
resolve and make decisions prior to January 2006. By working together, both parties will be able
to go forward with greater certainty to identify elements that will shape the Parks Master Plan and
to define project elements the I-405 South Renton Implementation Plan NEPA will examine. By
signing below, the City and WSDOT concur:
• The northbound I-405 to SR 169 ramp alignment recommendation will be carried forward
to the NEPA environmental document and final Section 4(f) determination for the South
Renton Implementation Plan project.
• The Wells and Parks Task Force commit to work together to expeditiously resolve
outstanding issues documented in the Wells & Parks Findings Report and other issues as
they arise.
• The agreed upon solutions will be examined in the South Renton Implementation Plan
NEPA Document,
• WSDOT will examine avoidance, minimization, and mitigation measures in the NEPA
environmental document, project design plans, and final Section 4(f) determination for the
South Renton Implementation Plan project.
Sincerely,
Crai J. Stone
