Revised trip generation estimates are presented along with design recommendations for the northerly access intersection. PROJECT OVERVIEW The proposed project comprises 265,000 square feet of commercial uses located west of El Camino Real and south and east of Calle Barcelona immediately north of the City of Encinitas. A portion of the project (47,413 square feet) will be second floor office uses and the remaining 217,5i'1"7::t square feet of ground floor uses will be retail. The retail component will have a variety of tenants (including restaurants) and hence can be classified as a shopping center. Trip generation estimates for the proposed project were derived from the Institute of Transportation Engineers (ITE) Trip Generation Manual, 6th Edition, and also from tbe SANDAG Trip Generation. The ITE land use category (LU 820) specifically addresses mixed retail uses such as this, and the trip generation is calculated using an equation which accounts for the size of the center in the trip generation rate. As can be seen, the total daily trip generation is estimated at 11,760 trips per day, with 324 in the AM peak hour and 1,121 in the PM peak hour. The SANDAG rates do not vary with size of center and result in a trip generation of 16,180 ADT with 590 in the AM peak hour and 1,646 in the PM peak hour. Although the ITE rates may be more representative of this type of center, both sets of trip generation estimates have been used to evaluate driveway volumes at the northerly access point. In this manner, comparisons can be made with respect to the findings under both sets of data.

Volumes at the northern driveway were added to the background traffic as contained in the previous traffic report to provide total turn movement volumes. These volumes are shown in the form of peak hour intersection capacity utilization (ICU) calculations in the appendix to this report. Lane configurations for the northern driveway assume single eastbound and westbound left-tum lanes and two thru-lanes in each direction. As can be seen here for the ITE trip generation rates, the PM peak hour ICU is .36 which represents level of service (LOS) "A" and for the SANDAG trip generation rates the ICU is .46 which also represents WS "A." Queue length requirements were calculated for the westbound left-tum volume in the PM peak hour. The queue lengths were determined from Synchro version 4.0 which uses Highway Capacity Manual2000 methodology in its calculations. The results are as follows; VOLUME lTE Trip Generation 290 SANDAG Trip Generation 455 QUEUE LENGTII (95m Percentile) 116feet 197 feet Hence the turn pocket needs to be 197 feet to accommodate traffic volume as estimated by the SANDAG trip rates (116 feet underthe ITE trip generation.) To account for higher volumes which can occur at shopping centers in weekends, it is recommended that the westboWld left-tum pocket be 300 feet in length. This provides for a potential 50 percent increase in left-turn volumes.

The project contains 260,000 square feet of commercial retail uses and was included in the Green Valley Master Plan at a higher square footage. Since this project was previously approved, only a site specific driveway analysis is being provided at this time. Attachment 1 shows the project site plan and location on the south side of Calle Barcelona, west of El Camino Real. Attachment 2 shows the project peak hour and average daily traffic volumes. Also shown is the traffic expected from La Costa Glen, the health and assisted living community planned to the north of Calle Barcelona. Attachment 3 includes the average daily traffic volumes expected on Calle Barcelona with the project traffic, with La Costa Glen traffic, and with through traffic added. These volumes are used in the traffic signal warrant analysis that follows. Attachment 4 includes a traffic signal warrant analysis for the three project driveways. As shown on these warrant worksheets, only the north driveway (Driveway A) is expected to meet traffic signal warrants. The approach traffic volumes are expected to be higher at this location since it is planned as the major entrance near the major stores and restaurants, and is the driveway near El Camino Real. 3100 C:\OFFICE_2000\ Trans. fax.2000\31 00. 6.2 7.00 4540 KEARNY VIUA ROAD, SUITE 106 • SAN DIEGO, CA 92123-1573 • (858) 560-4911 • FAX (858) 560-9734 Mike Shirey june 28, 2000 Urban Systems Associates, Inc. Attachment 5 includes a conceptual lane configuration layout, for discussion only, not for design purposes, at the Calle Barcelona(Driveway A intersection. The inbound PM peak hour traffic volumes are expected to need a dual left turn into the project driveway. Since Calle Barcelona through traffic in the westbound direction is expected to be of low volume, needing only a single lane, the westbound approach can be designed with a single through-right lane and dual left turn lanes within the existing 64 foot curb-to-curb dimension. Attachment 6 shows the intersection level of service calculation at the Calle Barcelona(Driveway A intersection which is expected to be at LOS A in both the AM and PM peak hour, which is an acceptable level of service. Driveway queuing areas will be provided as follows: Driveway A Driveway 8 Driveway C (11,151 ADT) (4,368 ADT) (3,094 ADT) (12x20 ft.= 240ft.) 2 lanes at 120ft. (5x20 ft. = 100ft.)
