Municipal Engineering

Helping Wisconsin communities maintain, modernize, and expand the infrastructure their residents depend on every day.

Partnering With Communities to Build for the Future

Lynch & Associates has deep roots in municipal engineering across Wisconsin. We understand the unique constraints and opportunities facing local governments - limited budgets, aging infrastructure, evolving regulatory requirements, and the constant pressure to deliver more with less. Our collaborative, hands-on approach means we work alongside municipal staff from concept through construction, ensuring every project delivers lasting value to the community it serves.

We leverage GIS mapping, hydraulic modeling, and asset management systems to help clients visualize their infrastructure conditions and make data-informed decisions - whether planning a capital improvement program or responding to an emergency.

Capabilities & Services

Water Distribution System Design

New water mains, system upgrades, fire hydrant placement, and service lateral design - ensuring reliable, code-compliant water delivery throughout your community.

Sanitary Sewer Design & Rehabilitation

New gravity sewer systems, lift station design, lateral lining, and manhole rehabilitation. We design for capacity, longevity, and minimal disruption during construction.

Stormwater Management

Detention basins, storm sewer relief pipes, watershed studies, and green infrastructure solutions that meet WPDES permit requirements and protect downstream properties.

Wastewater Treatment Facility Design

New facility design, plant expansion, and equipment upgrades - navigating DNR permitting while delivering cost-effective treatment solutions.

Urban & Rural Roadway Design

Street reconstruction, pavement rehabilitation, rural road improvements - coordinated with utility work to maximize project value and minimize community disruption.

Pedestrian & Recreational Infrastructure

Sidewalk networks, ADA curb ramp upgrades, park site development, and multi-use paths that make communities more walkable and livable.

GIS Mapping & Asset Management

ArcGIS-based mapping solutions that give municipalities a clear picture of their infrastructure inventory, condition, and maintenance needs - putting the data in your hands.

Grant Administration & Funding Assistance

We help clients identify, apply for, and administer grants from WDNR, WIFIA, USDA Rural Development, and other funding sources to stretch project budgets further.

Environmental Permitting

Wetland delineations, stream crossing permits, floodplain analysis, and dam removal permitting - we handle complex environmental reviews so you don't have to.

Representative Projects

Questions Communities Ask Us

What is a special assessment?

When a street or utility improvement directly benefits the properties along it, Wisconsin law allows municipalities to recover a share of the cost from those property owners. Each community sets its own assessment policy. We help our municipal clients calculate assessments consistently, prepare the required reports, and explain the numbers at public hearings - so property owners get clear answers before construction starts, not surprises after.

What should residents expect during street reconstruction?

Underground utilities come first - water, sanitary, and storm - then the street is rebuilt from the base up. Access to homes and businesses is maintained through construction, with short exceptions for concrete pours and utility tie-ins. On projects where we provide construction management, an inspector is on site daily and residents have a direct point of contact for questions.

How do communities pay for infrastructure projects?

Few municipal projects are funded from local dollars alone. We help clients identify, apply for, and administer outside funding - WDNR grant and loan programs, WIFIA, USDA Rural Development, and other state and federal sources - and we handle the compliance reporting after award, as we did for the Village of East Troy's dam removal and stream restoration.

We don't have an engineer on staff. How does working with you work?

That's true of most of the villages and towns we serve. We function as an extension of municipal staff - planning capital improvements, preparing budgets and grant applications, designing projects, and answering resident questions during construction - at a scale that fits local budgets.
