Saltworks Proposal- Transportation Group Summary Report (22 January 2010) 7A - ATTACHMENT NO.4 Page 23 for additional capacity in this section of Blomquist Street, there would be a need for additional right-of-way which could impact numerous existing land owners. The potential impact on this portion of Blomquist would need to be evaluated during a CEQA analysis using volumes generated by the travel demand forecasts prepared for the Saltworks project. 9. Existing Local Roadway Improvements - While the preliminary modeling indicates that the Saltworks project trips will replace many of the existing trips on the local and regional roadways and alter the travel patterns in the area, there will be additional trips on the local roadways and therefore the need for additional local roadway improvements if the project were developed. The operation of these local roadways and intersections would be included in a CEQA analysis to determine the level of impact and need for mitigation. 4.1.2 Conclusions Related to Site Access - Major Connections to Surrounding Roadway System The application and project description should clearly identify the features of the parallel roadway system and external roadway connections, including conceptual engineering drawings, which would need to be provided by the project. DMB is preparing supplemental information that will more clearly define the physical designs of these external roadway connections; however, a clear description of what the project proposes would be needed to provide a starting point for a CEQA analysis. A CEQA analysis would provide an understanding of the impact of property acquisitions and access modifications to create the external connections. Alternative connections or alignments may need to be studied for these major external connections in the event that they are prohibited due to right of way acquisition or other impacts. The evaluation of alternative roadway connection concepts could also be used to identify alternatives to the connections proposed by the project. During a CEQA analysis, the costs of any off-site roadway improvements or other major transportation infrastructure improvements would need to be identified as well as funding sources for these improvements. 4.2 MIXED-USE BALANCE As stated previously, the project description generally includes 8,000 to 12,000 residential dwelling units, 1,000,000 square feet of office and 140,000 square feet of retail space. Based on our review of the available materials and discussion with DMB, this land use mix has not been tested to see if the land uses are balanced to maximize internalization of trips. Therefore, there could be variations on the land use mix that could reduce external trips and mitigate potential impacts on the roadways. 4.2.1 Key Issues The following issues would need to be addressed as part of a CEQA alternatives analysis or to mitigate project impacts: 1. Determine whether the relative proportions of housing and jobs are well sized for purposes of maximizing internal interaction and minimizing external traffic impacts. 2. What measures and conditions are incorporated into the development that would assure the socio-economic match between jobs and housing? 3. Evaluate if the proposed development plan contains the appropriate amounts of local-serving retail, schools and recreational facilities to minimize external travel. 4. Are the locations of uses within the site, and the networks and amenities proposed for pedestrian, bicycling, transit, and auto connectivity appropriate for minimizing motorized travel? 5. Determine the impact of on-site amenities - e.g. playfields and access to open space - in terms of local and sub-regional travel demand. 16
