maximum roadway cancer risk value applies to residents located adjacent to the plaza location, along Owens Drive. Plaza visitors would have much lower exposure parameters. If we conservatively assume a visitor is present at the plaza for 2 hours/day, 365 days/year for 70 years, the risk from roadways is 4.2 in a million (5.4 for all cumulative sources), which is below the single- source threshold of 10 in a million. The actual value is likely much lower if more realistic exposure parameters are assumed. Staff also notes that the current level of such contaminants is expected to continue to decline due to more stringent emissions regulations. Trail Connections The applicant will be responsible for dedicating 10 feet of property along the east side of Site 1, and the northeast and west sides of Site 2 to accommodate trail connections to Owners Drive and BART. The applicant will improve these trails adjacent to the project with 8 feet of asphalt and two feet of landscaping. They will be responsible for maintaining the landscaping and the City will be responsible for maintaining the asphalt. Because the two sites do not connect, this will leave an approximately 365 foot gap in the trail between the two sites that would have to be filled in with right-of-way from either the Kaiser or Shaklee Corporation properties. While neither property owner has committed to providing the needed right-of-way, staff continues to discuss this need and is optimistic that a connection can be made as part of future development projects on either or both of the sites. Completion of Owens Drive Council members inquired as to what the timetable was for the completion of the narrowing of both the north and south sides of Owens Drive. As was mentioned at the Joint Workshop, no changes are required to be made to the center median, and the applicants are being required to complete the narrowing on the south side as part of their project. The narrowing of the north side was intended to be postponed until such time as the BART property was developed. Concerns were raised regarding what the widening on only the south side would look like, the period of time it would remain that way, and what the funding sources would be. Staff does not believe that completing only one side of the narrowing would be unattractive. The timeline for BART moving forward with development of their site is uncertain. While BART staff has prepared and approved a set of Development Standards and Design guidelines for the site that are consistent with the City's Standards and Guidelines for the TOD sites, there is no specific timeline for development and it is unlikely to occur within the next five years. BART staff has also indicated that they are unable to fund the improvements to narrow Owens Drive in advance of the redevelopment of their site. Potential funding for the north side improvements would include BART or its development partner, various North Pleasanton Improvements District funds, City CIP funding, or grants made available through the One Bay Grant Program.
