Stormwater Design
Our stormwater design solutions have helped municipalities across Colorado’s Front Range for over 20 years – many of which have been recognized by regional and national organizations for engineering excellence. Several of our projects have been tested by major flood events and have proven capable of withstanding flows much greater than the design frequency. ICON’s design services provide a full range of solutions including conduits and storm sewers, water quality planning and design, detention ponds, jurisdictional dams, and trenchless installations such as pipe boring/jacking/tunneling improvements. Each project incorporates of a full range of project solutions, project cost estimates, bid document preparation, permitting, outreach and meeting facilitation, and meeting local design criteria.
Stream Restoration & Stabilization
ICON’s well-rounded skill set includes open channel and stabilization improvements, intentional drop structure designs, channel rehabilitation, and wetlands restoration. We have expertise in working with stream geomorphology which focuses on sediment transport and natural stream design function. Geomorphic principals are inherent to our restoration planning and design projects. ICON has completed several studies and projects related to stream stability and sediment transport challenges where restoration activities provide a balance of geomorphic design, sediment transport, and ecological diversity.
Roadway Design & Multi-Modal Transportation
ICON provides engineering expertise related to roadway design, bicycle lanes, pedestrian systems, and construction. We are familiar with both CDOT and other local agency roadway design standards including AASHTO’s Policy on Geometric Design of Highways and Streets. Our projects include local, collector, and arterial roadways and state highways. We have completed many CDOT local agency projects requiring environmental, right-of-way, and utility clearances. Roadway designs typically include right-of-way drawings, construction phasing and traffic control plans, as well as drainage design that encompasses storm sewers, swales, permanent BMP’s, storm water management, erosion prevention, and sediment control plans.
Master Planning
ICON has vast knowledge and experience in the completion of Stormwater and Stream Restoration Master Plan studies throughout the Front Range. In general, each study involves a wide range of engineering tasks, including but not limited to hydrologic and hydraulic modeling, floodplain delineation, damage assessment, geomorphology, stream stabilization, alternatives analysis, economic analysis for benefits vs. costs, conceptual or preliminary design presentation, and report preparation.
Floodplain Analysis
ICON specializes in the completion of challenging floodplain delineation projects and Flood Insurance Study (FIS) updates, including FEMA Letters of Map Revisions (LOMRs), Conditional Letters of Map Revisions (CLOMRs) and Physical Map Revisions (PMRs); completing assignments related to FIS updates in all of the FEMA Region VIII states. ICON’s staff has experience in 1 and 2-dimensional modeling and unsteady flow hydraulics, including use of the FLO-2D, SRH-2D and HECRAS 2D software programs.
Trails, Parks & Recreation
ICON’s repertoire includes engineering design for major parks and trail projects. These projects involve site and infrastructure planning, preliminary and final design documents, water quality and Low-Impact-Development (LID) design, and construction management. Whether it’s a brand new trail, a sports park, or a children’s play area, our design work has often included ADA compliance, retaining walls, bridges, soft surface walkways, paved pathways, culverts, lighting, signage, play areas, landscape features, parking lots, and coordination with end users, interest groups, municipalities and water districts.
GIS & Web Solutions
Cutting edge technology is common to ICON’s current projects and planning studies. Data collection is often assembled with GIS attributes and seamlessly transitioned to web-based applications. ICON customizes web-based interfaces for continued interaction by users, making the plan both user-friendly and easily updated. Similarly, ICON integrates new tools and techniques to outreach and engage interested parties in our projects. For many projects, ICON develops custom project websites to display general project information, upcoming events, mailing list subscriptions, and web-based public commentary.
