Hazelton Avenue <br /> Stockton, CA 95205 <br /> Dear Ms. Hernandez: <br /> The California Department of Transportation appreciates the opportunity to review the <br /> proposed expansion of an existing unmanned trailer parking and storage facility from <br /> 200 trailers to a total of 439 trailers at 26901 South Hansen Road, Tracy. Operations will <br /> be 24/7 and access will be granted off Hansen Road. <br /> 1 . Caltrans previously commented on this project in a letter dated October 26, <br /> 2021. Those comments are still applicable and are included below. <br /> 2. Please submit to Caltrans for review and comment the pre and post <br /> construction runoff calculations and drainage plans so we can understand the <br /> flow patterns. The developer needs to ensure that the existing State drainage <br /> facilities will not be significantly impacted by the project. <br /> a. If historical undeveloped topography shows drainage from this site flowed <br /> into the State Right-of-Way, it may continue to do so with the conditions <br /> that peak flows may not be increased from the pre-construction quantity <br /> and the site runoff be treated to meet present storm water quality <br /> standards. <br /> b. If historical undeveloped topography shows drainage from this site does not <br /> flow into the State Right-of-Way, then it will not be allowed to flow into the <br /> State Right-of-Way at this time. <br /> 3. It is observed that Bio-swales were proposed to capture the onsite runoff, <br /> hydraulics would like to review the Basin calculations to understand the volume <br /> of runoff capacitated in the basin. Please submit the drainage plans and <br /> calculations to Caltrans for review and comment prior to project approval. <br /> "Provide a safe and reliable transportation network that serves all people and respects the environment" <br />
