Survey of Transit-Oriented Development Residential Properties in Santa Clara County
Dear Mr. Augenstein: With much pleasure, I would like to transmit to your office the final Technical Appendices (Volume II) for the above referenced project, which has been prepared by the graduate students of URBP 256: Transportation Planning – Local Issues (Spring 2010), under the leadership of Mr. Eduardo C. Serafin, PE, AICP. This volume includes the appendices to the main report, which details the findings of the parking utilization surveys of transit-oriented development (TOD) residential properties in Santa Clara County and provides empirical evidence that these types of development are “over-parked.” We would like to express our gratitude to the Santa Clara Valley Transportation Authority—particularly Mr. Robert W. Swierk, AICP and Ms. Ying C. Smith, AICP—for collaboratively working with our graduate students on this project, giving them the opportunity to gain real-world experience that could help shape future land development in the South Bay. We believe this report will be useful in your efforts in informing local decision-makers regarding the benefits of reducing local parking requirements for TOD residential properties in Santa Clara County. We would also like to thank you very much for acknowledging our students’ contribution with individual commendations letters. We consider this collaborative research project between SJSU and VTA an unqualified success for all parties involved. Sincerely,
Dayana Salazar Professor and Chair Department of Urban and Regional Planning

• Improvedurbanform(e.g.,gardenapartmentshaveagreateramountof“activestreet

This property has been selected as a potential location for data analysis. With your permission, a research team of 2-3 people will enter the parking area to count parking spaces and parked cars from 11PM to 5Am on a typical weekday during the week of April 6-8. There is no anticipated risk to you, the property owner or manager from allowing the research teams in the parking area of the property. There are no benefits for allowing the research teams in the parking area of the property. The results of this study may be published, but no information that could identify you, the property owner or manager will be included. Allowing the parking survey on the property is voluntary. If you decide to allow the research team to gather parking related data from the property you are free to not answer any questions and to withdraw at any time without any negative affect on your relations with San Jose State University or with any other participating institutions or agencies. No service of any kind, to which you are otherwise entitled, will be lost or jeopardized if you choose to not to allow the research. By signing below we will know that you have agreed to allow SJSU students from the Department of Urban and Regional Planning to enter the parking area and gather the necessary data of parked cars and parking spaces.
