Laying directly adjacent to the South Platte River, Riverside Park is the main park for the city of Evans, CO. When it was almost completely wiped out in the 2013 Colorado flood, it was a devastating blow to the community. While working at a previous employer, Jon Altschuld was the project manager for the flood recovery Master Plan for the park.

The Master Plan centered around a concept to completely re-grade the park area by lowering the 'native' portion of the park and raising the 'formal' ballfields area. This widens the floodplain in order to slow the velocities of high flows, and allows the water a 'safe' area to dissipate energy. This involved the removal/capping of a large unofficial landfill which was also a de-certified levee. The landfill material wreaked havoc during and after the flood by breaching and allowing flood waters into the park area, and subsequently holding the flood waters in the park. This resulted in the majority of the park being inundated for several days after the flood.

Re-construction of the park is currently underway, with planned completion in late 2018.
