Project Spotlight: Ligonier Beach Park Feasibility Study & Master Site Plan

Mackin is proud to be leading the feasibility study and master site planning effort for the revitalization of historic Ligonier Beach Park — a beloved community destination for more than 90 years.

Working alongside project partners and the community, our team is helping evaluate future possibilities for the site while balancing its rich history with modern recreation needs and long-term sustainability.

Projects like this are about more than planning — they’re about helping communities reimagine spaces that bring people together.

Earlier this week, our office welcomed a team of “Junior Engineers” for Bring Your Kid to Work Day, where they explored engineering through hands-on activities including hard hat decorating, traffic sign and safety lessons, a parking lot field view, measuring exercises and truss bridge building!

The day was filled with curiosity, creativity, and a lot of fun, it was exciting to see engineering come to life through their eyes.

Thank you to everyone who helped make the day such a success and to the families who joined us. We may have a few future engineering in the making!
