IV. SUBAREA PLAN PROVISIONS
SOUTH OF TREAT BOULEVARD
The area south of Treat Boulevard represents an important land resource suitable for intensification because of its proximity to the BART Station and adjacent access afforded by Treat Boulevard and I-680. Treat Boulevard, however, also functions as a barrier to pedestrian access to the BART Station and automobile access has been prohibited directly from Treat in order to maintain the vehicular capacity of the street.
Subarea 14A
This subarea in the southwest corner of the Pleasant Hill BART Station Area is separated by the raised BART tracks. In order to avoid severe obstructions to traffic flow on the north bound off-ramp of I-680 vehicular access to Subarea 14A shall not be permitted directly from Treat Boulevard. This restriction is also essential to avoid traffic safety problems which would otherwise exist. With this provision, Subarea 14A would become landlocked. The Specific Plan therefore provides for two options concerning this area. First, the development rights can be transferred to a portion of Subarea 14B (and presently the two areas are in the same ownership), with the condition that Subarea 14A be landscaped and maintained by the owners. Second, the site can be developed according to the facilities and site requirements in the Specific Plan and an internal circulation adjacent to Treat, beneath the BART tracks be incorporated to join the development to Subarea 14B. Unique to the Station Area, this development site may include business services and uses not otherwise permitted, e.g., storage. Uses would have to be of a low intensity nature, and include design features that would recognize the high level of visibility of the site. Design guidelines shall be developed and used to facilitate site planning and design.
The Circulation Policy reserves a 60 foot wide right-of-way centered on the existing Jones Road for future public access improvements. The reserve will retain the future option of using Jones Road as an exit off the north-bound off-ramp at I-680 beneath the BART tracks.
Subarea 15
This development area is the largest single development site except for the BART Station. As such it represents an important opportunity to achieve an integrated development. The Circulation Policy Diagram reserves a 60 foot wide right-of-way (ROW) for future public access at the southern and eastern perimeter of the development area (now Jones Road). This route will be developed primarily for internal access to any development on Subarea 15. This future circulation route may be required in order to retain intersection capacity along Treat Boulevard by providing an alternate route for through traffic along the east-west corridor. Precise alignment and design of the access road shall be reviewed at the time a specific project is proposed.
Offers of dedication along Jones and Oak shall be provided for to facilitate Iron Horse Trail installation.
The Urban Design Policy Diagram, Figure 7.2 provides for a second level pedestrian plaza within the development area oriented toward the intersection of Treat and Oak. This plaza shall provide commercial opportunities adjacent to an open, outdoor-use area and connect directly with the overhead pedestrian crossing of Treat Boulevard to the development in Subarea 12. Stairs or ramps, to connect this second level circulation route with Treat Boulevard shall be provided as part of the development project. Provisions shall be made to maintain necessary public circulation open at all times.
