MEMORANDUM
To: Geoff Stensland, Bellevue Badminton Club
From: Brad Lincoln, PE
Subject: Badminton America Parking Analysis
Date: July 20, 2018
Project #: 18-130
This traffic analysis summarizes the parking generation for the Badminton America development.
The development is proposed to convert 24,976 SF of existing building space from warehouse to a
badminton club. The badminton club is proposed to have 12 courts. The building is located on the
east side of Line Avenue SW, south of SW 7th Street. A site vicinity map in included in Figure 1.

1. PARKING GENERATION CALCULATIONS
The parking generation calculations for the Badminton America development are based on data
collected at a similar racquet sport sites, data contained in the latest Institute of Transportation
Engineers’ (ITE) Parking Generation, 4th Edition and testimony of expected operations.
1.1. Proposed Badminton Use
Badminton activity consist of either singles or doubles, meaning up to 4 people maximum on a court
at the same time. This is similar to a tennis court. Additionally, a foursome will typically include 2 to
3 of the players carpooling since friends and/or family typically play together. Adult lessons are
typically individual lessons. Youth lessons are group lessons, but parents typically drop-off the youth
before the lesson and pick-up the youth after the lesson. Badminton America uses a parking
calculation of 3 spaces per court to accommodate maximum parking demand at its various locations.
1.2. New Parking Generation
The parking demand that will be generated by the badminton use has been calculated based on the
number of courts. The parking generation data for ITE Land Use Code (LUC) 490, Tennis Courts,
and ITE Land Use Code (LUC) 491, Racquet/Tennis Club, has been used in the parking calculations.
It is important to data for ITE LUC 491 (Racquet/Tennis Club) included ancillary facilities such as
swimming pool, sauna, weight rooms, snack bar, etc. The data for ITE LUC 491 is therefore likely to
be more conducive to longer stays and multiple activities; unlike ITE LUC 490 (Tennis Courts) that
has greater similarities to the single primary use at the proposed badminton facility. ITE data for
weekday and weekend periods is summarized in Table 1.
Table 1: ITE Parking Data Summary
Period Average Parking Demand 85th Percentile Parking Demand
Saturday LUC 490
(Tennis Courts) 2.50 per court 3.16 per court
Weekday LUC 491
(Racquet/Tennis Club) 3.56 per court 4.13 per court
Saturday LUC 491
(Racquet/Tennis Club) 2.0 per court 2.0 per court
The ITE Parking Generation data is included in the attachments.
2. CONCLUSION
GTC recommends a parking demand of 3.56 per court to accommodate the maximum anticipated
parking demand based on existing ITE data for similar sites and the testimony experience at the
Mukilteo and Bellevue club. The Badminton America use is anticipated to result in the maximum
parking demand of 43 spaces for the 12 courts.
