ICON has established long term contracts with many Front Range municipalities to complete drainage related design improvements. Many of our projects have been recognized by regional and national organizations for engineering excellence. Our projects have been selected twice by the Colorado Association of Stormwater and Floodplain Managers (CASFM) for Grand Awards with an additional six Honor Awards. Several of our projects have been tested by major flood events and have proven capable of surviving flood flows even much greater than the design frequency. A prime example is our work on Spring Creek in Fort Collins that experienced a disastrous 11-inch plus storm of 1997 with minimal impact.
ICON’s design services include a full range of solutions, including open channel and stabilization improvements, drop structure design, channel rehabilitation and wetlands, restoration, 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 involves evaluation of a full range of project solutions, project cost estimates, bid document preparation, permitting, outreach and meeting facilitation, and meeting local design criteria.
ICON expertise includes stream geomorphology, focusing 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.
Mitigation Master Planning
ICON has vast knowledge and experience in the completion of Stormwater and Stream Restoration Master Plans studies. 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.
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), competing assignments related to FIS updates in all of the FEMA Region VIII states. ICON staff has experience in 2-dimensional modeling and unsteady flow hydraulics, including use of the FLO-2D, SRH-2D and HECRAS 2D software programs.
Roadway Design and Multi-Modal Transportation
ICON provides engineering expertise related to roadway design, trail systems and construction. We are familiar with both CDOT and other local agency’s roadway design standards including AASHTO’s Policy on Geometric Design of Highways and Streets. Our projects have included local, collector, and arterial roadways and state highways. We have completed many CDOT local agency projects which require obtaining environmental, right-of-way, and utility clearances. Roadway designs typically included associated right-of-way drawings, construction phasing and traffic control plans, drainage design, including storm sewers, swales, and permanent BMP’s, storm water management plans, and erosion and preparation of sediment and control plans.
Parks & Recreation
ICON’s repertoire includes engineering design for major parks and trail projects. These projects often include, site and infrastructure planning, and preliminary and final design documents, water quality and Low-Impact-Development (LID) infrastructure. Recent project examples include Johnson Habitat Park and Sun Valley Community Park for the City and County of Denver. Located along the South Platte River and Weir Gulch. These projects are based on concepts originally developed in the River Vision Implementation Plan (RVIP) completed by Denver Department of Parks and Recreation and the Greenway Foundation which was endorsed by the Denver City Council in November 2010. Both projects help return the land to a more natural state, increase riparian habitat and wetlands, and improve floodplain conditions. From a recreation standpoint the project provides better connect with the riverine environments and incorporate recreation programming specific to each site.
GIS and Web-based Interfacing
Cutting edge technology is common to ICON’s current projects and planning studies. Data collection is often assembled with GIS attributes and seamlessly transitions to web-based applications. ICON customizes web-based interfaces for continued interaction by users and to make 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 will develop custom project websites to display general project information, as well as upcoming events, mailing list subscriptions, and web-based comment.
