Our People Make the Difference


Hannah Marre, EIT

I strive to design safe and practical infrastructure so people of all abilities can walk and ride outdoors with confidence and experience the joy of self-propulsion!


Hannah graduated from The University of Portland in 2011 with a degree in Civil and Environmental Engineering and has since worked at several local engineering firms doing a variety of project types, including right-of-way ADA retrofits, site design, stormwater masterplans and on-site stormwater treatment. At Alta, Hannah has focused on off-street trail design, primarily working on the LA River Path project, which will eventually serve millions and create a continuous multi-use pedestrian and bike path through the heart of Los Angeles connecting uses to Long Beach and Union Station. Alta has offered Hannah a unique opportunity to have a much larger, positive impact by designing infrastructure for active transportation beyond the occasional curb ramp improvement.
