This is the last week to submit ideas for the second year of the Knight Green Line Challenge, a three-year competition to fund the best ideas to enliven St. Paul neighborhoods along the light-rail line.

Any person, business or nonprofit is eligible to enter the competition. There are two rules: projects must take place in and benefit one of six St. Paul neighborhoods along the Green Line (downtown, Frogtown/Thomas-Dale, Hamline Midway, St. Anthony Park, Summit-University or Union Park); and the ideas must energize current or future residents, expand economic opportunity, or strengthen civic engagement.

Total funding for the three-year project amounts to $1.5 million, with individual grants in the past ranging from $1,000 to $75,000. Projects will be judged on their potential impact, proximity to the Green Line and feasibility.

For an application and more information, go to Applications must be submitted by noon on Friday.
