The Watershed Company■ EAjBlumen June 2012 Site Conditions Prior to Conversion Prior to development of the fire station and roadway uses,the Conversion Site was primarily comprised of forested/vegetated areas and contained no emission sources. Air quality emission sources in the vicinity of the site prior to conversion primarily included vehicle emissions from the Sullivan Park parking lot and area roadways. Existing Air Quality Conditions Air quality at the site of the previous conversion is primarily affected by vehicular emissions from I-5 and 112th Street SE. The operation of the existing fire station(Fire Station#7) contributes building exhaust and periodic truck vehicle maintenance idling emissions to the area. Vehicular operations at Fire Station#7 and along the one-why roadway also contribute emissions to the area. Environmental Consequences Development of Fire Station#7 and the one-way roadway increased emissions on the Conversion Site when compared to the previous vegetated/forested condition of the site. However,the level of emissions generated on the Conversion Site was similar to or less than surrounding uses in the area(I-5, 112th Street SW, and commercial uses to the north) and did not significantly affect uses or activities associated with Sullivan Park. No further development is anticipated on the Conversion Site and emissions associated with Fire Station#7 and the one-way roadway would remain similar to the existing conditions. 4.3.2 Replacement Site Existing Air Quality Conditions The Replacement Site presently contains forested and other vegetated areas and contains no existing emission sources. Air quality in the Replacement Site area is primarily composed of emissions from vehicular traffic on I-5 (to the east of the site) and, to a lesser extent, 112th Street SE(to the south of the site). Environmental Consequences The Proposed Action would convert the existing vegetated Replacement Site into a new public park with trails, seating areas, and picnic tables. Construction of the proposed park would result in temporary short-term increases in dust and emissions associated with equipment operations and construction vehicle trips to and from the site. Subsequent to construction,the operation of the proposed park would not directly generate any new emissions and no impacts to air quality are anticipated. Some vehicular traffic and associated emissions would be generated Page 19
