About Tierra Plan

We are a small, nimble team that values hard work, collaboration, and building enduring relationships with our clients. Unlike engineering or environmental services companies with additional GIS developers, we are a team of experts who specialize in creating bespoke and well-considered web mapping applications for planning and engagement.

Our approach

We believe in being clear, collaborative, and engaging. We approach each project with care, flexibility, and the goal of creating highly useful tools and great relationships. We don’t take a black-box approach to application development, but coordinate closely with our clients, including regular opportunities for knowledge sharing, input, review, and testing. 

Our team

We’re an efficient team with skills in database architecture, geospatial software development, and information design. 

Tierra Plan was born from a shared love of solving interesting problems.

Founder Kevin Knapp met Bryan and Sarah when we collaborated on map-based planning websites way back in 2009.

Since then, we’ve been honored to create amazing tools for hundreds of great clients.

Our simple strategy is the same today as it was 15 years ago: 
work hard, be nice, and keep getting better.
