CITY OF FEDERAL WAY
RE: Permit #15-101430-00-SM; Proposed CVS Pharmacy at 33520 215' Ave SW;
Request for variance to driveway spacing standards
Dear Mr. Wecker,
This letter responds to your request to modify the City's driveway spacing standards on 21s' Avenue
Southwest, as part of the proposed CVS Pharmacy development at the location referenced above.
After evaluating the existing conditions along the referenced street, review of your variance request, and
the analysis provided by Transportation Engineering Northwest JENW), dated March 23, 2015, the
Public Works Department hereby approves your request for a variance to the driveway spacing standards.
Federal Way revised Code (FWRC) Section 19.135.290(2), allows the Public Works Director to
administratively grant a modification to reduce the access spacing standards by up to 20 percent. Your
modification request substantially exceeds the 20 percent threshold; however, based on (11e analysis
provided by TENW, the City will allow the development to proceed with the driveway locations and
turning movements as shown on the Site Plan - Attachment A - of the TENW analysis.
This approval will be applicable for a period of one year from the date of this letter. 1f a Complete Land
Use Application is not submitted for the project within the one-year time limit, then this waiver will be
void, and a new request for modification must be submitted. If a Complete Land Use Application is
submitted within the one-year time limit, then this approval will be valid for (lie duration of the Land Use
Approval issued for the project.
If you have any questions regarding this approval, please feel free to contact Erik Preston, Sr. Traffic
Engineer at (253) 835-2744, or Kevin Peterson, Engineering Plans reviewer at (253) 835-2734.

City of Federal Way
Attention: Rick Perez, P.E.
33325 81h Avenue South
Federal Way, WA 98003
Subject: Federal Way CVS Pharmacy Variance Request
Dear Rick,
The following is a variance request relating to the proposed CVS Pharmacy. The store would be
located on the east side of 21 st Avenue SW, north of SW 336th Street on the lot of the existing 76
Gas Station. The variance is requested for driveway spacing as it relates to a proposed shared full
access driveway located off of 215t Avenue SW.
Project Access
Access to the CVS site would be provided via an existing right -in right -out (RIRO) driveway on SW
336th Street, and a relocated BIRO driveway on 21 st Ave SW. In addition, CVS proposes a new
internal connection (via easement) to a proposed full access driveway on the adjacent AutoZone
property to the north. The AutoZone full access driveway would be constructed concurrent with the
CVS site (see attached Site Plan included as Attachment A).
The proposed full access driveway on 21,11 Avenue SW would be located approximately 80 feet
south of the existing Fire Department driveway (centerline to centerline), and approximately 150 feet
north of the proposed RIRO driveway on the CVS property. This proposal does not meet the City's
driveway spacing standard for adjacent driveways, which states that same -side driveways must be
separated by a minimum of 150 feet regardless of which property they are on. Therefore, this
variance is being requested for acceptance of reduced driveway spacing to the adjacent fire station
driveway.
The provision of a full access driveway to 21 st Avenue SW is crucial for the function of the proposed
CVS Pharmacy. Absent this access point, the CVS site would have no immediate access to 21 st
Avenue SW in the souhbound direction or SW 336th Street in the eastbound direction, and would
require a u-turn at the 21,IV336th signalized intersection for users utilizing the north access. In
addition, without the full access and internal easement connection, the existing AutoZone would be
limited to only a RIRO access, with access to the site only coming from 21 st Avenue SW for users
travelling in the northbound direction.
Design Standards
Applicable design standards for driveway spacing on 21 st Avenue SW were found in the City of
Federal Way Public Works Development Standards, Rev. November 2014. Per section 3.2.13
Driveways, the minimum driveway spacing is 150 feet to any intersection or to any other same -side
driveway, whether on or off the subject property. This standard applies to all non -State Route arterials
and collector streets (see attached City of Federal Way Standards included as Attachment B).

Variance lustification
It is not possible to meet the City's 150 foot driveway spacing requirement to the adjacent fire station
driveway due to limited property frontage lengths and close proximity to the 215t Avenue SW and
SW 336rh St intersection. To maximize spacing between adjacent driveways and comply with the
access management standards, the full access driveway is proposed to be located 330 feet from
the 215t/336th intersection. The new CVS BIRO driveway would be located 150 feet south of the
full access driveway (centerline to centerline). This would satisfy the City's minimum driveway spacing
requirement (see Attachment A for dimensions).
Driveway alignment with SW 334rh Place was also analyzed to ensure that concurrent left -turns could
be accommodated at the opposing driveways. The SW 3341h Place driveway primarily serves the
Parkway Apartments Complex on the west side of 215t Avenue SW. There are multiple constraints
which preclude the ability to align the CVS driveway with SW 334rh Place. Alignment with the
existing SW 334rh Place would require encroachment north onto the adjacent fire station property,
which could have significant impacts on the usability of their current access. This would also require
the relocation of an existing Puget Sound Energy transmission pole, fire hydrant, and various other
utility components located behind the sidewalk. Thus a slight offset would be present between the
opposing driveways. Attachment C illustrates that concurrent opposing turn movements would
function acceptably.
Conclusion
In summary, this Variance requests approval of less than the standard 150 foot driveway spacing
requirement between the proposed CVS/AutoZone full access and adjacent fire station access based
on the following justifications:
• Due to limited property frontages, it is not possible to provide a full access to 2151 Avenue
SW while maintaining 150 foot driveway spacing standard to the adjacent fire department
driveway.
The proposed driveway spacing for the full access and RIRO driveways would meet City
spacing standards.
■ The full access driveway would be located 330 feet from the intersection of 215t Avenue
SW and SW 336rh Street, satisfying the Class 2 Access Management Standards.
■ Entering Sight Distance would meet/exceed minimum standards for the proposed
movements.
Provision of the shared full access driveway and CVS Pharmacy/AutoZone connection would
reduce traffic volumes at the existing driveways and would reduce u-turn movements at the
215t/336th and 215t/334th signalized intersections.
■ The proposed full access driveway is critical to site economics and usability of the CVS
Pharmacy.

+ Per AutoTURN, the proposed 25 foot centerline offset from the existing SW 334th Place
would allow for concurrent opposing entering and exiting maneuvers onto 21 st Avenue SW.
+ The proposed location of the full access driveway maximizes spacing to the fire department
driveway while achieving standard spacing to the proposed RIRO access and SE 336th
Street intersection.

3.2.14 Sight Obstructions
The following sight clearance requirements take into account the proportional
relationship between speed and stopping distance.
The sight distance area is a clear -view triangle formed on all intersections by extending
two lines of specified length right and left from the intersecting street along the centerline
of the through street and connecting those endpoints to form the hypotenuse of the
triangle. The area within the triangle will be subject to restrictions to maintain a clear
view on the intersection approaches.
Intersection Sight Distance TrianRl_e:
A. Areas around all intersections, including the entrance of driveways onto streets,
must be kept clear of sight obstruction. Intersection sight distance shall be
determined based on posted speed limits per AASHTO requirements. FWRC
19.135.130 establishes what may be in the area that is to be kept clear of sight
obstructions.
B. The vertical clearance area within the sight distance triangle will be free from
obstructions to a motor vehicle operator's view between a height of 2.5 feet and
ten feet above the existing surface of the street.
C. Exclusions
The following are permitted to be within the area that must be clear of sight
obstructions:
Any structure erected before the effective date (2-27-90)
2. Natural topography of the ground. However, the Public Works Director
may require land surface modification to fulfill the intent of this division
of FWRC as part of any development activity on the subject property.
