DRC2009-00023, Springfield Fire (Jasper/57th Station)
Date:
To:
From:
The Transportation Division has reviewed the materials provided with the subject
application where the Springfield Fire Department is proposing to purchase property with
a federal grant to construct a new fire station to serve the Jasper/Natron area.
Bob Straub Parkway (BSP) is a major arterial that has limited access controlled by Lane
County. Access from this site directly to BSP would not be allowed per current policy
nor would it be optimal for this location, The local access proposed on S57th Street is
preferable as the lower classification of roadway per SDC 4.2-120(B) which states that
"Driveway access to local streets is generally encouraged in preference to access to
streets of higher classification. Exception: Driveway access to arterial and collector
streets may be permitted if. .. or where heavy use of local streets is inappropriate due to
traffic impacts in residential areas."
The physical attributes of the site, including site access, driveways, and local network
access appear to be acceptable given the proposed design. To examine "heavy use of
local streets" the ITE Trip Generation Manual, 8th Edition contains insufficient data on
which to base a trip generation estimate, For the purposes of this application a
comparable station was used to estimate the number of trips that would be generated by
the proposed development in order to assess the impact on the surrounding transportation
network. As the applicant's narrative has stated that Station 16 is similar in the
conceptual design of the proposed station, the trip log for that facility was used as a
model. Due to the proposed staffing at the new facility being less than that at the 68th
Street (Station 16) location, the estimated trip count is conservative. The following data
was derived from recorded call volume and staffing of the existing station:
Ave. Engine Calls:
Ave. Medic Calls:
Staff:
Ave. Total Outbound Trips:
Ave. Total Trips/day:
3/day
8/day
5/day
16/day
32/day
Based on the estimated number of total trips/day, existing transportation facilities are
adequate to accommodate the 'additional volume of traffic generated by the proposed
development.
