Development projects and changes to roadways in the north Salmon Creek area have neighbors worrying about the quickening pace of their quiet neighborhood.Construction for a Fred Meyer gas station was recently completed, with a soft opening this past weekend and a grand opening scheduled for later this month. The off-site gas station is part of a small retail complex across the street from the Salmon Creek store at 800 N.E. Tenney Road. The site will also be home to a credit union and a coffee house with a drive-through.“I think (the gas station) is definitely going to have a negative impact on traffic flow,” said Ann Foster, vice president of the North Salmon Creek Neighborhood Association. “People are going to be lining up on Third Court getting in and out of there.”With the possibility for an influx of cars in the area on the immediate horizon, other traffic changes are expected down the road. Just east of the Fred Meyer gas station, at the northeast corner of Northeast 139th Street and 10th Avenue, a commercial development project is in the works.MAJ Development, which specializes in retail projects and is the same developer that planned the retail area that includes the Fred Meyer gas station, has recently ironed out some of the wrinkles in their plan to develop a 20.8-acre project. Five parcels of land, the most visible of which is home to a crane yard for DeWitt Construction, were all approved to be rezoned from light industrial and apartments to general commercial in 2008. At that time, however, rezoning included conditions that would cap the number of cars allowed to travel through the area during rush hour, or 5 to 6 p.m.
