BOULDER, Colo. (CBS4) – The Sierra Club is calling this Colorado Flood Recovery Weekend as hundreds of volunteers stepped up to help rebuild.

“The fact that people jumped on this was really encouraging,” Bryce Carter with the Sierra Club said.

The effort came with less than a week of planning.

“We clean up people’s homes, help clean up the reservoirs, the greenways and really rebuild the community,” Carter said.

Nearly two dozen organizations were involved in the all-volunteer event to clean up family homes and areas like the Boulder Reservoir.

“Big turnout, got the mayor over here, it’s nice to see,” volunteer Ted Noyes said.

“This group is rebuilding the beach which obviously got ripped apart during the high waters,” Boulder Mayor Matthew Appelbaum said.

After the flooding much of the beach at the Boulder Reservoir was washed away and what was left was filled with debris.

“It’s okay to mail off a check, but to physically be here and help the people of Boulder,” volunteer Susan Gemmill said.

It’s happening at nearly a dozen locations across Boulder, Lyons, Longmont and Greeley.

“This is really a small number. I know we have hundreds and hundreds more people just eager to go,” Appelbaum said.

It’s an eagerness that doesn’t surprise the volunteers who came from all over the state, and when help is needed in Colorado, it comes in droves.

The events were happening all weekend and will end with a celebratory appreciation party Sunday night in downtown Boulder.

“Anybody whose lived here knows the people here really care about their community,” Appelbaum said.
