Our press releases keep you up to date on current events at S2O Design. Tune in for news about our latest projects, developments, and company milestones.
One of the things I love about S2o is how personally we take our work. All of us kayak, all of us love whitewater, and all of us have a vested interest in making sure that the parks that we make come out with amazing results. It goes without saying that we take our projects very personally.
Perhaps the project that has hit the closest to home, however, is the Lyons recovery projects that we have become involved in. S2o was back at work in Lyons within a week of the disaster striking. Our number one goal was working with the Town of Lyons, FEMA, and the other federal and state recovery agencies such as the NRCS, CWCB, State of Colorado, Colorado Parks and Wildlife, etc.
Putting the engineering work aside the critical path on these efforts are funds. If Lyons wants to come back, it needs to have money. Our staff has now volunteered countless hours to help the Town of Lyons apply for a number of grants from all kinds of sources including a $1 million grant from Great Outdoors Colorado for parks recovery, a $1.6 million grant for trails recovery, and a number of $100,000 to $300,000 grants for stream and riparian zone restoration. We continue to search out these opportunities.
At S2o we are proud to be pursuing these funding opportunities because we believe that the recovery of this Town is founded in rebuilding and recreating the great outdoor recreational opportunities that fuel our central business district.
Lyons, CO: Colorado Governor John Hickenlooper visited Lyons, Colorado today to announce the recipients of the Great Outdoors Colorado (GOCO) Flood Recovery grants for 2014. The Town of Lyons came away the big winner with a $1 million dollar award for the reconstruction of Meadow Park.
“This park is central not only to our community, but to our economy”, said Parks and Recreation Director Dave Cosgrove. S2o worked with Cosgrove as well as others in the community to help define the project, craft the grant, and create conceptual designs to aid GOCO in visualizing Lyons’ concept for the new and improved Meadow Park.
“We have a lot of projects we are working on at S2o right now”, said S2o Director Scott Shipley, “but the thing we are most proud of as a team are our efforts to help our hometown recover from the flood.” The $1 million dollar grant will aid Lyons with the more than $4 million dollars in damages that occurred in Meadow Park during the September 2013 flooding event. Rainfall in that month created flows of greater than 20,000 cubic feet per second in a streambed that normally runs less than 600 cubic feet per second. The disaster is credited with causing more than $50 million dollars damage to the Town as a whole.
“The great thing this grant does, more than any other funding so far, is begin the process of recreating Lyons as a destination for visitors and as a rebuilt Town for the people of Lyons. This is one of our first projects that is designed to welcome people back to this community”, commented S2o Engineer Nathan Werner. The funding will be put to use almost immediately as the S2o and DHM designed phase 1 of meadow park begins construction later this month.
The Lyons Emergency Channel and McConnell Flood Berm at peak design flow.
One year ago S2o Design and Engineering completed an emergency flood channel through the Town of Lyons for the Federal Emergency Management Agency (FEMA). The channel routed down both the North and South Forks of the St. Vrain and beyond the Confluence for 1/2 mile. Creation of the Emergency Flood Channel protected the Town of Lyons from subsequent flooding during run-off the following year and allowed the Town time to create and implement a well-designed river restoration project in subsequent years.
It has been almost 16 months since the Town of Lyons, CO was devastated by a 1 in 500 year flood. Over 30,000 cubic feet per second flowed through a channel that typically peaks at 600 cfs in any given year. The flood damage rearranged channels, swept away homes, trapped people on any one of seven separate “islands” and left behind a tremendous amount of damage.
The Town itself was evacuated but for those residents who chose to stay and, “essential businesses”. One of those essential businesses was S2o Design and Engineering. A local Whitewater Park/River Engineering firm that is based in downtown Lyons.
S2o immediately began to partner with the Town, State, and Federal Government to aid with the recovery. This included detailed damage assessments, which has helped the Town to recover its losses; immediate damage recovery, such as the design of the work that put the river back under McConnell Bridge and allowed residents to return home, and a number of other, equally important tasks. We continue to partner with Lyons on the tasks associated with rebuilding this Town.
One of the most important tasks was the design of the Lyons Emergency Channel. This project was initiated by FEMA, in cooperation with the Town, and allowed for the creation of an emergency channel through the Town. The purpose of this channel was to create enough flow capacity, in the channel and under the bridges, to accommodate a run-off equal to the 1-in-5 year flood, should that occur in the year after the disaster. S2o was commissioned to do this work. A later phase of work is tasked with recreating the natural morphology and restoring the habitats along this reach of the river. This work is ongoing.
In-Channel construction work as the channel is excavated and armoring is placed to protect homes in the confluence area from further flooding.
The project direction was, get it done right, and get it done quickly. The Town needed the work completed prior to spring run-off. S2o commissioned a survey of the streambed throughout Town and, foreseeing the construction, had the surveyor leave stakes and elevations at 400 foot intervals throughout the project area. S2o Engineer Dan Woolley then used hydraulic software to design and draft a channel that accommodated the necessary flows in both the North and South Channels with S2o designer Christine Clark making the construction drawings in parallel with Dan’s work.
The project also required the design of flood berms to prevent the evulsion of the channel at the failure points that had occurred during the previous flood. S2o Engineer Nathan Werner, a reformed Dam Engineer, designed berms that protected a number of homes from repeat damage in a project that also allowed the McConnell Causeway to be rebuilt. The entire project was bid, and built, by March of last year.
It is not often that an engineer gets to their work tested at the extreme limit of design but this project did in fact see design flows this last summer. S2o Engineer Scott Shipley spent several evenings in May and June with a flashlight inspecting berms throughout the Town. The result, not a single issue that required maintenance. Even in a rushed environment each part of the project remains s2o strong one year later!
Organizers of the Lyons Outdoor Games came to S2O Design with an urgent request: Can you pull together whitewater for this year’s Lyons Outdoor Games? A 1-in-500 year flood event devastated the town of Lyons, CO in 2013 and damaged a large swath of Town around the river. While the Town is committed to continuing its outdoor games, venues have needed to be re-created in order to host many of the events. S2o was asked to help create both the Slalom and Freestyle venues. S2o worked with the Town of Lyons Department of Parks, Recreation, and Cultural Events and the local parks and recreation commission as well as organizers of the Outdoor Games to create the whitewater park needed for the games to occur.
S2O Design donated more than $10,000 in in-kind services and also sponsored the event. As a part of its efforts S2O Design worked with local stakeholders to design and lay-out the slalom and freestyle venues and then applied for USACE and FEMA permits required to work in the active waterway. The improvements included creation of a freestyle feature at the Black Bear hole and stabilization of the riverbed at the former location of the “A-Hole”, installation of a bendway weir to redirect flow off the south bank, and random boulder placements for slalom eddies and character.
The redesign has been a resounding success. The Freestyle feature is in and creates a great venue for the competition. The new eddies and pools also create a much better reach for the slalom races during this year’s Lyons Outdoor Games. “We are so excited to have world-class features for this year’s outdoor games” said event Organizer Rebecca Louzan, “we look forward to having some of the country’s best paddlers here on May 30th for the games”.
The Lyons Outdoor Games is a premier Colorado outdoor lifestyle, adventure sport and music festival. There will be a number of events focused around Bohn Park including a kid’s climbing wall and drink craft microbrew from over 50 craft microbreweries around the country. There will also be a number of world class athletes competing in professional kayaking, dirt jumping and slacklining comps! Visitors can sign up for this year’s Beer Relay or kick off your flip flops and jump on a slackline. Music will be performed by national touring acts and there will be concessions for food and beverages.
S2O Design is excited to have helped make this event happen. We are proud to provide our services to enhance great events like the Lyons Outdoor Games and to make Lyons a better place to live, visit, and recreate in.
