Why Heneghan & Associates?

Heneghan Storm Water Featured Projects

Our goal is to provide our clients with feasible projects that can be implemented in a timely manner to meet their needs.  HA’s professional staff provides continual communication throughout the project’s analysis/feasibility study, design, permitting, construction, and funding process to provide creative/practical/collaborative/cost-effective solutions.  Solutions which result in budget conscious reliable systems requiring minimal maintenance and providing consistent performance year after year.
Heneghan’s team has an extensive portfolio of experience necessary to address storm water projects, as small as localized drainage problems of less than 1 acre to system-wide improvements with regional detention covering hundreds/thousands of acres.  We work proactively to assist clients with efficient and cost-effective solutions, while maintaining regulatory compliance.  Our experience with storm water management is well documented.  See OUR WORK for sample projects.
Heneghan’s team works with you from the beginning of the project to provide funding solutions to enable your projects to be implemented.  Our vast funding experience includes providing project budgets, cash flow analyses, and storm water rate studies.  In addition, we assist in obtaining government funding through various grant and low-interest loan programs, and assist in developing storm water utility user fees.  See our FUNDING ASSISTANCE page for additional details.
We are in the middle of difficult times with aging infrastructure, increasing regulations, increasing regulatory enforcement, and diminishing funding sources.  During times like these we realize that client needs cannot always be met with standard methods so HA offers alternative project delivery methods (Design/Build and Design/Build/Finance) through our partnership with Heneghan Construction Services, LLC (HCS).  The Design/Build method allows for faster project completion, reduced engineering fees, collaborative versus adversarial relationships, and a single-point-of-contact.  The Design/Build/Finance method allows clients to meet their current financial constraints by spreading out the project payments over a period of years while still resolving their problems immediately by constructing the project now.  See our Design/Build Construction service page for more details.
