SUBJECT:Traffic Scoping Memo
Long Shot Indoor Range Expansion – Yelm, WA
TENW Project No. 2022-183
This memorandum documents the preliminary traffic information for the proposed Long Shot Indoor Range
Expansion project for the purpose of establishing a scope of work for the Traffic Impact Analysis (TIA). This
memo includes a project description and trip generation estimate.
Project Description
The existing Long Shot Indoor Range site is located at 16910 SR 507 in Yelm as shown in the Attachment A
Site Vicinity Map. The existing site includes a 9,850 square foot (SF) building consisting of retail and storage
space. The proposed expansion project is anticipated to be built in two (2) phases. Full buildout of the
proposed expansion is expected to include 34 shooting bays (22 shooting bays in Phase 1 + 12 shooting
bays in Phase 2).
Vehicular access to/from the existing Long Shot Indoor Range site is currently provided by two (2) full access
driveways: one (1) each on Grove Road SE and SR 507. No changes to vehicular access are proposed as
part of the proposed expansion project. A preliminary site plan is provided in Attachment B.
Project Trip Generation
The most recent version of the Institute of Transportation Engineers (ITE) Trip Generation Manual does not
include a land use category for a shooting range. Therefore, trip generation estimates for the proposed project
were based on an alternative approach using Land Use Code (LUC) 432 (Golf Driving Range). A golf driving
range was assumed to be comparable to a shooting range based on the general operational characteristics
of both (similarity between the independent variable of shooting bays and driving tees, the presence of a
“pro shop or small refreshment facility” per the ITE definition, general hours of operation, etc).
Based on the addition of 34 shooting bays, the resulting weekday PM peak hour trip generation estimate
associated with the full buildout of the proposed Long Shot Indoor Range Expansion project is summarized in
Table 1. Detailed estimates are included in Attachment C.
These estimates are likely conservative in that no reductions were made to account for existing customers who
currently use the existing facility without the range and would therefore already be at the facility without
generating new vehicle trips.

Upon your review of the above trip generation, we would like to confirm if any additional traffic impact
analysis would be required to complete your review of the proposed Long Shot Indoor Range project.
