Tustin Avenue and a sit-down restaurant at 301 N. Tustin Avenue. The site is generally located south of Fourth Street and east of Tustin Avenue. Both properties are located in the Professional (P) zoning district. 301 N. Tustin Avenue has a General Plan land use designation of Professional & Administrative Office (PAO) and 325 N. Tustin has the General Plan land use designation of General Commercial (GC). As proposed, the Project requires approval of a general plan amendment to change the land use designation from PAO to GC, zone change from P to Commercial General (C2) and a conditional use permit for the proposed drive-through services. The Project will include the development of a commercial building with a drive-through and a gas station convenience store at 301 and 325 N. Tustin Avenue, respectively. The Project would include construction of a 7,417 square-feet (SF) commercial building with drive-through to replace a 4,200 sit-down restaurant and a 2,778 SF gas service station convenience store to replace the existing gas station building and car wash. Please note that the proposed Project will provide internal access between the two parcels.  Study Scope – The following four (4) key study intersections and one (1) key roadway segment were selected for detailed peak hour and daily V/C / level of service analyses under Existing Traffic Conditions, Existing Plus Project Traffic Conditions, Year 2019 Cumulative Traffic Conditions and Year 2019 Cumulative plus Project: Key Study Intersections 1.
