Municipal Infrastructure for Everyone.

Public agencies face growing demands to improve infrastructure, serve expanding communities, and make the most of limited public resources. MacKay partners with cities, counties, ports, and other public agencies to deliver practical, community-focused infrastructure solutions. By bringing together expertise from across our firm, we help clients navigate funding, permitting, regulatory requirements, public engagement, and every stage of project delivery.

We partner closely with public agencies to deliver practical solutions that reflect local priorities, support long-term performance, and make the most of public investment. From planning and design to construction and public engagement support, our multidisciplinary team helps clients navigate complexity with confidence and deliver projects that create lasting value for the communities they serve. 

Our Municipal Expertise

  • Aerial view of a multi-lane roundabout in a green, wooded area, with cars circulating, crosswalks and yield markings, and a landscaped central island near a small pond.

    Roads & Streets

    Our team delivers transportation and infrastructure solutions that improve and safeguard communities. We design streets, stormwater solutions, roundabouts, and other critical transportation infrastructure that keep people moving safely, efficiently, and economically.

    Community & Recreation Facilities

    We prioritize people in everything we do, and our team recognizes that community and recreational facilities serve as more than buildings or open space; they become the heart of public life. We bring both technical skill and a deep understanding of how well-crafted recreational areas foster relationships and bring people together.

    General Utilities & Infrastructure

    When it comes to essential utilities and infrastructure projects, we offer a specialized skill set and expertise that travels to every site. We provide planning, design, and construction solutions for essential utilities and critical infrastructure, ensuring communities have what they need to operate safely and efficiently.

    Downtown Revitalizations

    We help breathe new life into downtown areas through smart urban design and engineering. We help local governments modernize aging infrastructure, improve pedestrian safety, and create welcoming public spaces. By integrating strategic vision with durable utility, parking, and streetscape solutions, we lay the foundation for sustainable economic growth that serves the local community.
