Meet the Staff

PCTPA has been around for a while, with a history that dates back to 1978.  Many of our projects and programs can be seen throughout Placer County, from highway improvements to public transportation that is accessible for everyone to Freeway Service Patrols to bikeways to repavement programs.  What you may not be familiar with, however, is who we are...

Leading the agency since 2018 is Executive Director, Mike Luken. Mike has more than 34 years of experience in the fields of transportation, economic development, and city planning. Mike raised his family in West Roseville and has resided in Placer since 1989. Prior to coming to PCTPA, Mike served as the Deputy Director of the Yolo County Transportation District. Mike has also worked for the cities of West Sacramento, Sacramento, the County of Yolo, served as the Director of the Port of West Sacramento and worked in the private sector prior to coming to PCTPA.

As PCTPA Deputy Executive Director, Rick Carter works closely with the Executive Director Mike Luken, to execute PCTPA’s work program efforts, focusing on the timely and cost-effective execution of PCTPA-led transportation projects and programs. Rick’s extensive knowledge and record of success in improving transportation infrastructure throughout the Sacramento region made him our top pick to join PCTPA. In his more than 25 years of experience in the region, Rick has done it all, including all phases of capital project delivery, transportation funding and planning, and rural transit system management. Born and raised in Orange County, CA, Rick studied Civil Engineering at California State Polytechnic University Pomona and is a registered Civil and Traffic Engineer. After graduating college, Rick moved to the region to take a job at Caltrans as a Bridge Engineer. Since then, Rick has held increasingly responsible positions as a transportation project manager at El Dorado County Department of Transportation (DOT), the Capital Program Manager at the City of Elk Grove, and most recently, managing transportation funding and bicycle, pedestrian, and transit programs at Sacramento County DOT.  In his free time, when not playing soccer, Rick enjoys golf, or coaxing his wife, son, or daughter out to kayak, bike ride, or play disc golf.

Planning Administrator and Board Secretary, Solvi Sabol believes that her career was “meant to be.” She’s a Placer County native whose family includes three generations of public servants at the County, so it was a perfect fit when she started work for Placer County 25 years ago. Sabol was first employed with the Placer County Public Works Department. At that time, Placer County Transportation Commission (PCTC), now known as PCTPA, was housed under Public Works. As PCTPA became its own agency, the Executive Director saw Sabol as a perfect candidate for the Administrative Assistant position and convinced her to apply. She has been with PCTPA ever since, and feels that she “grew up with the agency.” For Sabol, transportation projects are “more than roads, bus routes, and bikeways,” because she believes these projects represent a potential to improve the quality of life for Placer residents. It’s about getting people to where they need be efficiently and safely. Sabol enjoys living in Newcastle with her husband and finds that Placer County has been an ideal place to raise her two children. Solvi can be reached at via phone at 530-823-4030 or via email at ssabol [at]

Coming up on her one-year, Jodi LaCosse has been working for PCTPA since August of 2021, serving as the Fiscal and Administrative Offer. She was born and raised in Orange, which is located in southern California. Her area of expertise is rooted in 15 years of public finance. She has always enjoyed working in finance and appreciates the cyclical nature of it, which is why she chose this career. Jodi believes that PCTPA benefits the community by helping to improve the lives of those living in the region. Some of the hobbies and things she likes to do in her free time involve spending time with family and friends, camping, and boating. Specifically in Placer County, her favorite place to visit is the foothills.

Senior Transportation Planner David Melko originally came from Wallingford, PA and has served at PCTPA for the past 11 years. David brings 36 years of planning experience involving not only transportation, transit, and airport, but also land use, flood control and environmental issues. David currently works on Airport Land Use Commission, the Freeway Service Patrol Program, the Western Placer Consolidated Transportation Services Agency, and many transit studies. David finds planning work satisfying because transportation planning is a collaborative process. When many different stakeholders provide their input, they can combine their expertise to create better plans for local transportation projects. Without stakeholder feedback, PCTPA would not be able to plan effective and safe connections between communities and their destinations. When David is not coordinating with the Airport Land Use Commission or working on a transit study, he is running, bicycling and going to the gym. David’s favorite band the Beach Boys, circa ’66 to’73, also paved the way for his favorite type of music – progressive rock (aka “prog music”). And although he cheers for Penn State football, David is the biggest fan of his son and daughter. David can be reached at via phone at 530-823-4090 or via email at dmelko [at]

In December 2021, Mike Costa took on the position as PCTPA’s Senior Transportation Planner. Mike primarily assists with the short- and long-range transportation and transit planning, and fund programming efforts. He also serves as lead staff support for the Western Placer Consolidated Transportation Services Agency (WPCTSA). Prior to coming on board, Mike served as the Transit System Manager for the City of Elk Grove. His passion is helping bring transportation opportunities to communities that need it the most and providing transportation alternatives to this region.  During his spare time, Mike enjoys hiking in the Auburn Ravine, wine tasting in the Sierra Nevada foothills, relaxing on the shores of Lake Tahoe or somewhere in the California Central Coast, as well as traveling both within the country and internationally. Mike is looking forward to working on developing a short-range transit plan for Placer County’s transit operators and assisting with a marketing plan to help promote those public transit services in the Placer County region. He sees PCTPA benefitting the community in many ways including connecting all partnering cities, towns, and County agencies with federal and state financial resources, helping establish a coordinated planning approach, and maintaining and building local and regional transportation networks for all.
