ENGINUITY is a full-service water resources engineering firm. Specific areas of expertise and described below:
Enginuity has worked on numerous master planning projects and understands the challenges, pitfalls, and solutions to deliver successful master planning documents. Some of the keys to success include:
- Making use of the most efficient planning methods,
- Addressing water quantity and quality issues,
- Addressing local drainage issues,
- Identifying long-term capital improvement plans, and
- Providing an easily updateable master plan.
Our approach to your master plan provides you with easy access to critical stormwater data, is easily updateable, and provides for a capital improvement program that addresses flood hazards with practical and constructible solutions. The master plans we develop for you will:
- Become the foundation of the stormwater infrastructure capital improvement program,
- Clarify funding sources for such a program,
- Establish floodplain boundaries, drainage infrastructure and regulation for future development
- Address water quality implementation, operations and maintenance and long term asset management.
Floodplain Management is an evolving profession. What used to be a process of determining floodplain limits and managing development to those limits has now become a much more involved effort. Managing flood hazards is now a process of not only understanding the flood hazard itself, but also how entire river systems are affected by development and changes in the environment. In effect, a present day floodplain manager's goal is finding ways to minimize impacts to the river system and fully realize the natural and beneficial functions of the floodplain corridor. Enginuity works within these guidelines to assist out clients with floodplain management challenges.
The Enginuity team has an extensive background working with the Federal Emergency Management Agency (FEMA), the Colorado Water Conservation Board (CWCB), UDFCD, and multiple local agencies in order to complete the following types of analyses:
- Hydraulic modeling of stream systems (1D and 2D)
- Floodplain mapping, modification studies, and review
- Floodway modeling and delineation
- FEMA Conditional Letter of Map Revision(CLOMR)/Letter of Map Revision (LOMR) analyses and submittals
- NEPA floodplain technical assistance
- Floodplain development permit assistance
Due to key staff's past experience working as contractors to both CWCB and FEMA during FEMA's Map Modernization and Risk MAP Programs, we possess an insider's knowledge of the following to assist communities:
- FEMA's Knowledge Sharing System (the new official Guidelines and Specifications reference)
- Working with FEMA Region VIII's Professional Technical Services Contractor to facilitate CLOMR/LOMR and floodplain study reviews
- Key relationships with FEMA Project Managers; and
- National Flood Insurance Program and the Community Rating System Program
Enginuity’s passion for moving the stormwater industry forward has resulted in the implementation of complex hydrologic and hydraulic modeling practices seamlessly integrated into every day stormwater planning and design for our clients along the Front Range. Not only have we modeled thousands of square miles utilizing traditional CUHP, SWMM, and HEC modeling programs, but we are constantly striving to utilize new technologies to save both time and money while also providing more accurate and detailed results. Some of these practices include:
- Extensive use of 2-D hydraulic and sediment transport modeling (FLO-2D, GSSHA, SRH2D, RiverFlo2D, ParFlow)
- Performing the first study of rain-on-grid hydrology calibration effort for the UDFCD
- Performing the first re-calibration effort of CUHP in almost 40-years
Channel Migration and Erosion Zone Mapping: Enginuity is working with UDFCD and Douglas County to develop the first Channel Migration and Erosion Zone Mapping for 14 Miles of Plum Creek. After the 2013 Floods, the State has indicated that erosion, avulsion, and channel migration zones should be considered with floodplain management. Enginuity is helping develop and deliver these new requirements for UDFCD.
Regional Hydrologic Update: We have been trusted by UDFCD to lead the re-calibration of the Colorado Urban Hydrograph Procedure (CUHP), which is the single largest hydrologic procedure in the Denver and Aurora Metropolitan Areas.
Rain on Grid Hydrologic Modeling: We are the forerunners for modeling urban drainage systems with rain-on-grid technology in the Denver area. With Rain-on-Grid modeling we pay attention to every inch of the urban catchment instead of only the outlets of drainages. This allows for a more comprehensive understanding and assessment of flooding risks, small storm drain systems, pollutant transport, and benefits of LID practices. Enginuity has calibrated three separate rain-on-grid models for final recommendations on proper modeling procedures for tomorrow’s hydrologic methods to be used today.
Channel restoration and rehabilitation poses many challenges. First and foremost is the location of the stream itself; is it urban or is it rural? Our team has performed design for both applications using many of the standard methodologies in the engineering community today provided by the Natural Resource Conservation Serivice, the Urban Drainage and Flood Control District, The U.S. Army Corps of Engineers, U.S. Fish and Wildlife, and numerous local entities and professionals. Our stream rehabilitation and restoration services include:
- Stream restoration;
- Stream stabilization using bioengineering;
- Open channel design;
- Grade control structure design;
- Hydraulic analysis and geomorphology;
- Wetland mitigation design; and
- Trail and separated crossing design.
Many proposed highway improvements involve replacement or widening of bridges over streams. It is imperative that several elements be reviewed on these types of projects including flood conveyance, floodplain impacts, accommodation for wildlife and recreational activities, stream morphology, and scour caused by the structure itself. Our team has extensive experience on bridge projects and has performed numerous hydraulic analyses for highway bridges, pedestrian bridges, and utility crossings. Some of our key services include:
- Bridge hydraulic analysis
- Bridge scour analysis
- Scour countermeasure design
- Bridge sizing and freeboard analysis
- FEMA CLOMR/LOMR assistance
Solving client problems using technology has been a focus of Enginuity since our inception. We are committed to using the latest technology on projects whether it be the latest computer models, GIS, or innovative project delivery. Two of his most recent accomplishments include the development of a CIP cost estimating tool used for all planning studies for UDFCD called UD-MP Cost. The UD-MP Cost tool is a sophisticated spreadsheet with visual basic programming which provides standardized cost estimating within the entire Flood Control District. As a follow-on, Enginuity has been working to develop the StormWater InFormation Tool (SWIFT); a GIS extension for master planning database entry, cost estimating, and program management.
- Customized spreadsheet development;
- Research studies;
- GIS application development; and
- Hydrologic and hydraulic model studies.
Providing hydrologic and hydraulic services for transportation projects is about communication, coordination, and knowing your ultimate client and what their requirements are. Our staff has worked on numerous transportation projects from large interchanges in metropolitan areas to small rural highways traveling through National Forests. In every case, understanding the clients criteria and requirements has been the foundation of success. Building on that foundation, close coordination with roadway engineers, structural engineers, and environmental scientists paves the way for project success. Our team has the right experience to deliver on your transportation projects. Some of our services for transportation projects include:
- Hydrologic analysis;
- Culvert and storm drain design;
- Ditch analysis and sizing;
