Civil Engineering


LACO’s engineers have the experience, professional licensure, and problem-solving skills that help Tribes, public agencies, developers, and people resolve issues and achieve their goals.  Our teams strives to work collaboratively with our clients, project stakeholders, and regulatory agencies to determine cost-effective and robust engineering solutions.

LACO works with the client team to understand the long-range goals and evaluate the water supply needs of each project. Our team has experience with source, supply, and delivery system design of these systems. We work to fold in the goals of self-sufficiency and resiliency into our design approach.

We also understand that reliable and compliant wastewater systems are the cornerstone of a healthy and prosperous community. Whether it’s applying the fundamentals of design to the collection system or researching and applying new and more reliable technologies in the treatment and disposal of wastewater all while staying up to date on the regulatory environment, our team takes on the challenges so that our clients have the tools and resources necessary to overcome the barriers associated with owning and operating these systems.

LACO’s engineers bring decades of experience in road, street, and highway design to the doorstep for our clients. It doesn’t matter the size or complexity of the project; our team is always looking for the most cost-effective and durable design for our clients. We continually stay up to date on the changes associated with these standards so that we can advocate for our clients and navigate these processes on their behalf. The LACO design and engineering team has extensive experience with all types and phases of site development, including commercial, industrial, single-family residential, and high-density residential projects.
