Land Development Services’ (LDS) Site Development and Inspections Division (SDID) is pleased to announce the promotion of two individuals into key leadership positions.

Kirsten Munz, Director of SDID, said, “I am thrilled with the new leadership these talented individuals bring to our team in SDID. With their strong technical backgrounds, and deep commitments to customer service, SDID is well positioned to continue to evolve and grow to better serve the development community and citizens of Fairfax County.”

Bin Zhang, PE, has been promoted to the Assistant Director of Engineering for SDID. In this new position, Bin will provide technical leadership and expertise over the plan review process, overseeing the four plan review branches. In this role, she will promote efficiency, consistency and teamwork among all stakeholders and participants. Bin will lead internal training and improvements to processes and resources related to site review, while strengthening our relationships with industry and our partner agencies.

Bin has worked in SDID for over 12 years, first as the Tysons site reviewer, and most recently as the chief of the North Branch, where she has been intimately involved in a wide range of highly complex, high-profile projects. She has demonstrated her ability to provide strong leadership among diverse stakeholders, upholding important regulatory requirements while remaining committed to delivering top-notch customer service. Bin’s technical proficiency and exceptional ability to distill complex processes and problems into clear, streamlined systems and solutions are an ideal fit for this new role.  

Daniel Rizzo, PE, has been promoted to Chief of South Branch plan review. In this position, Dan will provide leadership to a diverse group of engineers and code specialists performing plan reviews in Franconia, Mason, and Mount Vernon Districts.

Dan came to LDS two years ago after over a decade of extensive civil engineering design and project management experience in the private sector. As a stormwater specialist for the past two years on the South Branch team, he has reviewed numerous projects and studies, where he has skillfully collaborated with diverse stakeholders to find common sense solutions, and provide clear guidance to submitting engineers. Dan’s creativity and innovation will be an outstanding addition to the SDID leadership team in developing new policies and tools to promote consistency and streamline our processes.
