HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR <br />CITY OF SANTA ANA <br />5. Environmental Analysis <br />TRANSPORTATION AND TRAFFIC <br />Table 5.13 -1 HCM 2000 Level of Service Descriptions <br />Level of Service <br />Description of Traffic Conditions <br />Controlled Delay (seclveh) <br />A <br />Insignificant delays: no approach phase is fully utilized and no vehicle waits longer <br />< 10 <br />than one red indication. <br />B <br />Minimal delays: an occasional approach phase is fully utilized. Drivers begin to feel <br />> 10-20 <br />restricted. <br />C <br />Acceptable delays: major approach phase may become fully utilized. Most drivers <br />> 20-35 <br />feel somewhat restricted. <br />D <br />Tolerable delays: drivers may wait through more than one red indication. Queues <br />> 35-55 <br />may develop but dissipate rapidly, without excessive delays. <br />E <br />Significant delays: volumes approaching capacity. Vehicles may wait through <br />> 55-80 <br />several cycles and long vehicle queues form upstream. <br />F <br />Excessive delays: represents conditions at capacity, with extremely long delays. <br />> 80 <br />Queues may black upstream intersections. <br />Soumz:1B12013. <br />The minimum acceptable level of service established by the cuculation element is LOS D for major <br />intersections in the City, except in major development areas, where LOS E is the minimum acceptable LOS. <br />Intersections are considered significantly impacted if an unacceptable peak hour level of service is created by <br />the project or if the project increases the V/C at the study intersection by 1 percent of capacity (0.010 when <br />the intersection already operates at an unacceptable level. <br />Congestion Management Plan Facilities <br />The Orange County Congestion Management Program requires that a traffic impact analysis be conducted <br />for any project generating 2,400 or more daily trips, or 1,600 or more daily trips for projects that directly <br />access the CMP highway system. Per the CMP guidelines, this number is based on the desire to analyze any <br />impacts that add 3 percent or more of the existing CMP highway system facilities' capacity. The CMP <br />highway system includes designated CMP intersection and CMP arterial monitoring locations. <br />The CMP monitors the level of service at all designated CMP intersections in the county. The Congestion <br />Management Plan establishes LOS E as the minimum level of operation for CMP roadways (freeways and <br />Smart Streets). A significant impact is caused by a 1 percent increase in V/C (0.010 if the CMP intersection <br />already operates at LOS E <br />Harbor Boulevard, 1st Street, and Warner Avenue west of Harbor Boulevard are designated CMP arterials. <br />Designated CMP intersections include: <br />Page 5.134 PlaceWorkr <br />
