SUBJECT: Right Size Parking Project
Jim Haggerton, Mayor
Issue
A significant project to evaluate parking demand and supply has occurred in Tukwila and
throughout King County. The results of that study are available for review and discussion.
Background
King County is interested in helping jurisdictions and developers build successful transit -
oriented communities. Because parking plays a significant role in this type of development, King
County Metro has undertaken the Right Sized Parking (RSP) Project. Information on local
multifamily residential parking demand has been assembled to guide parking supply and
management decisions in the future. Incentives for actions to reduce parking supply or to
manage the supply through a range of tools is also being developed.
Discussion
The Project Manager for the Right Size Parking Project will provide background to and a
demonstration of the King County Multi - Family Residential Parking Calculator
http: / /www. rightsizeparkinq.orq/
Tukwila parking requirements are two parking stalls per multi - family unit that contains up to
three bedrooms. Mr. Rowe will present field data on how that requirement compares to actual
demand for the stalls. The Calculator also shows the cost of parking stalls and the impact on
rent.
Financial Impact

WHAT IS THE "RIGHT SIZE" FOR PARKING?
Right- sizing parking means striking a balance between
parking supply and demand. Although field data collection
found some projects that were not oversupplied, on average
parking was found to be oversupplied with 1.4 spaces built
per dwelling unit but used at only about 1 space per unit.
Applied to a typical suburban project with 150 units, the
result is roughly $800,000 spent to build unused parking.

WHY DOES IT MATTER?
Over - building parking supply leads to increased automobile
ownership, vehicle miles traveled, congestion and housing
costs. In addition, it presents barriers to smart growth and
efficient transit service.

OPTIMIZE PARKING FOR
SUSTAINABLE COMMUNITIES.
Right -sized parking can increase housing
affordability, economic development,
access to transit, and support livable,
walkable communities.
RIGHT SIZE YOUR CODES.
The project has created new tools to
help adjust zoning code to reflect local
characteristics of parking use. Try out the
Website Calculator, read the Policy Memo
online, and watch for the results of future
pilot and demonstration projects.
RIGHT SIZE YOUR PROJECTS.
Our research found that parking use
depends on location and context. The
Website Calculator estimates use based on
ricing, transit access, location of jobs and
people, and building characteristics.
THE RIGHT SIZE PARKING
CALCULATOR
This map -based tool allows users to
create custom scenarios for a specific
parcel. The user adjusts the scenario using
variables related to the building and its location, including
proximity to transit, price of parking, jobs and population,
and more. Understanding the influence of these variables
helps determine how much parking is "just enough" for a
particular site.
