Most homes located in Arvada's floodplain were constructed before the floodplains officially existed. Arvada's floodplains took effect in 1974 and most of the neighborhoods along the creeks; including Ralston Creek, were already built.
Just a few inches of water can cause tens of thousands of dollars in property damage. Visit the flood insurance page.
