Aurora is setting up a new development authority to address safety and disinvestment concerns along East Colfax Avenue. The authority will use tax-increment financing for improvements, and a seven-member board could be in place later this month to oversee this work. The area, which has been blighted by crime and empty storefronts, has seen marked marked improvements. Business owners and employees have complained about police responding to suspicious activity and high call volume. The Aurora Downtown Development Authority (DDA) will oversee improvements. The first task will be to finalize the Colfax Community Vision and Action Plan.
