From The Longmont Times-Call (Anthony Hahn):
According to the complaint filed this week, commissioners approved the floodway expansion over the resistance of local residents, who said the re-mapping would limit development on their private properties — some of which are functioning farms — and cause their flood insurance rates to skyrocket…
The re-drawing was performed by the Colorado Water Conservation Board, with assistance from Boulder County staff, and was approved last month 2-0 by commissioners. Commissioner Cindy Domenico was absent. When the change officially takes effect Oct. 1, it will substantially widen the floodway along portions of Lower Boulder Creek northwest of Erie.
A floodway is a narrow channel where, in the event of a flood, water will be flowing. A floodplain is where shallow water is likely to be during the event of a flood, though shallower and flowing at a lower volume, if at all, than water in a floodway.
The former, by definition of Boulder County’s standards, is more heavily regulated than a floodplain. Land regulated under floodway status is often limited to very specific redevelopment.
According to the complaint, plaintiffs’ efforts to have the hearing delayed to learn more about proposed expansion went unheeded…
The Colorado Water Conservation Board in 2015 changed the definition of a floodway, triggering a review of flood-hazard areas across the state. Wheeler Open Space, however, was not reassessed, given the lack of residential buildings on the land, Boulder County Senior Assistant Attorney Kate Burke said earlier this year.
In light of the planned oil and gas development on the site, a modeling with the new standards was performed. Under the new guidelines, the entirety of well site Section 1, which is in the open space, is within a floodway, according to documents Boulder County submitted in mid-April with its formal comments to the Colorado Oil and Gas Conservation Commission.
