Home My WebLink AboutRPT 4 SAN JUAN VACAT'N 07-05-88OATE: ~UNE 28, 1988 ~.~y .... I TO: WILLIAM HUSTON, CITY MANAGER FROM: PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION SUB,JECT: PROPOSED SAN JUAN STREET VACATION, FILE #2422 RECOMMENDATION: Pleasure of the City Council. BACKGROUND: In September 1987 the City Council authorized Staff to proceed with a traffic analysis to investigate the feasibility.of vacating a portion of San Juan Street adjacent ~to Tustin High School and Lambert Elementary School.. This authorization came as a result of Caltrans' request to the City to consider the vacation of San Juan Street. The firm of Austin-Foust Associates was the City's selection to complete the ~nalysis of this potential street closure. ~altrans' request for street vacation came after their initial contacts with the Tustin Unified School District had surfaced the District's concerns over losing approximately 3 acres of land along the E1 Camino Real frontage of Tustin High School. This 3 acre loss would reduce an already substandard size high schoo~ site to approximately 24 acres. · The vacation of a portion of San Juan Street would allow the residual TuBtin High School site to be physically joined with the Lambert Elementary School site which is approximately 10 acres in size. DISCUSSION: The firm of Austin-Foust Associates, Inc. has completed the San Juan Street Closure Traffic Analysis (copy previously furnished) of which a general summary is as follows: 1. The study area is bounded by E1 Camino Real on the South, Red Hill Avenue on the East, Bryan-Avenue on the North and Newport Avenue on the West. Ten primary intersections surrounding San Juan Street were also evaluated. 2. Traffic generated by the residences and schools on and around San Juan Street was estimated, .with through traffic on San Juan Street being estimated by means of a license plate matching study. Levels of service on the key intersections were tabulated on exist- ing traffic counts. ,. Levels of service at key intersections were then tabulated on a long range time frame and the impacts of the Street closure assessed. SAN JUAN STREET VACATION June 28, 1988 Page 2 Section II of the analysis outlines the following areas: * Existing average daily traffic (ADT) volumes on the key streets within the study area. * Existing peak hour (A.M., Noon and P.M.) turning movements at key intersections. * Through traffic study by use of a license plate matching study. Through traffic on San Juan Street ranges from 26% in the A.M. to 37% in the P.M. Section III of the analysis summarizes the amount of traffic diversion which would occur with the street closure and the impacts of that diversion: * The through traffic diversions generally have minimal impact on the key intersections with the exception of E1 Camino Real and Red Hill Avenue. The Intersection Capacity Utilization (ICU) rate increases 4% from 1.29 to 1.33, or Level F. This level of service is based on a two-lane facility on E1 Camino Real in lieu of the ultimate four-lane facility. * Ail other key intersections show either no change, or only a change of one percent in the ICU level. Some local traffic using San Juan Street' to access Newport or Red Hill Avenue will be forced to use Utt Drive, Lance Drive and Walnut Street. * The long range impacts (Past 2010) were tabulated for the two critical intersections of E1 Camino Real at Newport Avenue and E1 Camino Real at Red Hill Avenue based upon a four-lane roadway on E1 Camino Real. These intersections continue to operate at less than desirable levels, but the impacts increase only from 0% to 2%. In the event the City Council elects to proceed with the San Juan Street vacation proceedings, the following is a suggested procedure: * Refer to Planning Commission for their finding that the vacation of San Juan Street will be in conformance with the General Plan. * Return to City Council for adoption of Resolution of Intention for the street vacation. SAN JUAN STREET VACATION June 28, 1988 Page 3 * Hold public hearing on the street vacation and make final determination. It is estimated that the street vacation proceedings would span a period of 8-12 weeks.

STREET CLOSURE IMPACTS Through Traffic Diversion Local Traffic Diversion Long Range Impact~ III- 1 III- 1 III- 7 APPENDIX o I. INTRODUCTION This report describes the results of a traffic study carried out' to determine the traffic impacts associated with closing ~m Suan Street east of Orange Street and west of Charloma Drive in the City of Tustin. BACKGROUND AND SCOPE As ~ of the 1-5 widening project to be carried out by Caltrans, additional right=of=way will be required on the north side of El Camino Real between Newport Avenue and Red Hill Avenue. Acquisition of this right-of-way will result in a net reduction in the Tustin High School property. A potential mitigation measure would be to close San Juan Street east of Orange Street and link the school properties north and south of San Juan Street into a single unit. The purpose of this study is to examine the traffic impacts of such a closure. The study area is, identified in Figure I-1. Of primary concern are the 10 intersections surrounding San ,Iuan Street. These intersections, which are most directly affected by traffic along San Suan Street, were first studied to assess existing traffic conditions. Traffic counts were made for AM, Noon, and.PM peak hours at each intersection. In addition, ADT volumes for the study area were ob~ined from recent counts made by the City of Tustin. The second part of the analysis estimated the amount of traffic generated by the residences and schools on and around San Juan Street. Through traffic on San Juan Street was then estimated by means of a license plate matching study. The trip generation numbers were combined with the through traffic totals to define the current usage characteristics of San Juan Street. Based on the resulting traffic data, the amount of diversion that would occur due to the street closure was calculated. Impacts of these changes on intersection levels of service and increased travel times ~vere then estimated. The final part of the analysis examined a longer range time frame. Predicted levels of service at key intersections were tabulated and the impacts of the street closure again assessed. - San Juan Street \ COLINA z LAKE IRVINE BLVD .

EXISTING CONDITIONS This chapter describes the traffic characteristics of the area being studied. Existing arterials are discussed and their present day volumes and revels of service are summarized for use in the closure impacts section. ~URROUNDING ARTERIAL NETWORK San Juan Street is'a two-lane road with a signalized intersection at Red Hill Avenue. services a residential neighborhood, Tustin High School and an educational/day care building. It Traffic accesses San Juan Street primarily from Newport Avenue and Red Hill Avenue. Newport and Red Hill Avenues are four=lane arterials with left turn pockets at major intersections. Newport Avenue provides access to I=5. via a northbound on,-ramp and southbound off-ramp. Red Hill Avenue provides full access to the I=5 freeway. Other arterials of interest to this project are Bryan Avenue and E1 Camino Real. These two streets run parallel to San Juan Street and are the alternative routes for through traffic between Newport and R~cl Hill Avenues. E1 Camino Real is a two=lane secondary road with !eft turn pockets at Newport and Red Hill Avenues. Bryan Avenue is a four-lane road without additional left turn storage space. AVERAGE DAILY TRAFFIC Existing average daily traffic (ADT) volumes are illustrated in Figure II-1. Newport Avenue and Red Hill Avenue are high volume arterials, with Newport Avenue carrying volumes between 29,000 and 34,000 vehicles per day (VPD) within the study area, and Red Hill Avenue carrying 32,000 vehicles per day near I-5 and 17,000 north of Bryan. El Camino Real is the principal arterial for east-west trat~fic between Newport Avenue and Red Hill Avenue, carrying 10,000 to 12,000 vehicles per day. The traffic along San Juan Street, is significantly lower than that'of either El Camino Real or Bryan Avenue, with about 4,000 vehicles using this street. Bryan Avenue carries between' 6,000 and 10,000 vehicles on an average week day.

These counts were surveyed on weekdays during February and March 1988. To assess existing levels of service for the ten local intersections surrounding San Juan Street, intersection capacity utilization (ICU) rates were calculated based on the above peak hour traffic counts. The resulting ICU values are presented in Table II-l. Detailed ICU summaries can be found in the apl~endix. These ICUs are based on a methodology which assumes signalization, even though some intersections are currently unsignalized as noted in the · table. As the ICU table indicates, most intersections currently operate at level of service "D" or better. The exceptions are E1 Camino Real at Newl~ort Avenue which is at level of service "E' in the PM, .and E1 Camino Real at Red Hill which operates at level of service 'F.' Both of these inter~-ctions are located adjacent to the Santa Aha Freeway (I-5). As noted later in this report, long range plans are to improve El Camino to full, four-lane secondary standard, which would reduce these high ICUs significantly, TI-IROUGH TRAFFIC A license plate matching study was conducted in March 1988 along San Juan Street. This allowed the volume of traffic which uses the street to travel from Red Hill Avenue to Newport Avenue, or vice versa, to be determined. The results of this analysis are as follows: Percent of Through Traffic Time Period Northbound Southbound Total AM Peak Hour. 27% 25% 26% Noon Peak Hour 29% 27% 28% PM Peak Hour 38% 37% 37% As this 'table indicates, the percentage of through traffic varies from 26 percent in the morning to 37 percent in the evening. An average of 30 percent of all traffic using .San Juan Street on a daily basis is through traffic. 11-3 II--4 ®*V ~JodM®N I.' I!

As indicated, the existing land uses on and a~ljacent to San Juan Street are estimated to generate approximately 2,971 trips per day, with 471 trips during the AM peak hour and 435 trips during the PM peak hour. The actual counts for February and March, 1988, when adjusted for through traffic trips, can be compared to these trip generation estimates as follows: Trio Gen. Actual ADT 2,971 3,150 AM Peak Hour 471 586 PM Peak Hour 435 459 The minor differences are primarily due to the number of trips generated by the high school, a certain portion Of which use E'I Camino Real and not San Juan Street. A' summary of the traffic characteristics for San' Juan Street can be seen in Table II-3. This shows the number of trips using the street, separated into local and through traffic. ADT at the Newport Avenue end is 4,000 VPD, of which 1,350 (34 percent) is through traffic. At the Red Hill end, the volume is 5,000 VPD, of which the 1,350 through traffic represents only 27 percent.

STREET CLOSURE IMPACTS - The closure of San Juan Street to. through traffic would cause current through trips to be diverted, and would cause some re-routing of local trips to take place. This chapter discusses the amount of diversion that would occur and the impact of that diversion. THROUGH TRAFFIC DIVERSION Aa previously exhibited, between 26 and 37 percent of all traffic along San Juan Street are through trips. With the closure of San Juan Street, these trips would divert to E1 Camino Real, and to a lesser extent to Bryan Avenue. For the purposes of this study, a worst case scenario was used in which all trip diversions are routed to £I Camino Real. Under these circumstances, the trip diversions would affect the most critical intersections. Figures III-1 and 1II-2 illustrate the number and direction of movement of the estimated trip diversions for AM and PM peak hours respectively. Figures III-3 and III-4 present the resulting turn volumes, which take -into account the diversions, £or the respective AM and PM peak hours. The imffact of the trila diversions on intersection capacity utilization is presented in Table III-1. As indicated in this table, the trip diversions have minimal impact on most intersections. The one exception is the intersection of El Camino Real and Red Hill Avenue, during the PM peak hour the ICU value will be increased by four percent from 1.29 to 1.33. All other intersections show either no change or a change of only one percent in ICU level. Note that these ICUs again assume the existing two-lane configuration for El Camino rather than the four-lane section planned for this facility in the future. LOCAL TRAFFIC DIVERSION Some local traffic using San Juan Street to access Newport Avenue or Red Hill Avenue will be forced Under the street closure to use other facilities. Utt Drive, Lance Drive and- Walnut Street are the facilities that are primarily effected in that regard.

The area is.divided here 'into' three sectors, and trips to and from each sector involve some additional travel time and distance due to the dive~sion. These calculations assume a travel time of 25 miles per hour and that commuters will choose the shortest alternative travel route.

'LONG RANGE IMPACTS The ICU data presented above considered the impacts on-present day traffic volumes. In the future, additional traffic is forecast for Newport Avenue, Red Hill Avenue and E1 Camino Real. The most recent source of data for long range projections is the Tustin Ranch/I=5 Interchange Traffic Analysis. The estimated volumes give some idea of anticipated growth trends in this area, although the assumptions made in that 'report are not consistent with the recent Memorandum of Understanding (MOU) between the Cities of Irvine, Orange, and Tustin. That MOU has a "two-legged" corridor configuration, the west leg being of expressway standard and having no connection with I-5, while the above noted report indicates a single, north-south ETC alignment. Table Ill-2 summarizes the ICUs from the above referred source for the critical intersections with El Camino Real. The project impacts are also shown here, it being assumed that growth in through traffic on San Juan Street would not exceed 50 percent, and that the local traffic diversion would remain unchanged. In all cases, the full, four-lane secondary III-7 CAy :j.fodMeN I 0 III-8 TabLe III-2 INTERSECTION CAPACITY ANALYSIS - LONG RANGE POST-2010 la/OUT DIVERSIONS POST-2010 U/DIVERSIONS INTERSECTION , ~14 PI( HR Pt4 PC HR AH PK,HR P# PK HR EL Camirm RasL/Ne~port 1.04~ 1.10 1.GG 1.10 EL Camino R~L/Red HtLL 1.04, 1.~, 1.0~ 1.37 ,, lClJI ere caLcuteted on the basis of signalized intersection, ~hereis those denoted here with an asterisk ere currently un~igrmLized.
