Donors and co-locating agencies create projects in pursuit of more than one of six benefits. Typical combinations include the desire to both enhance access and to strengthen partnering agencies. The hope: to strengthen agencies that have a shared mission. The goal: simultaneously promoting sustainability and innovation. These are only the most common combinations. When done well, all real estate and location decisions are made with the intention of building community. However, the attempt to aid neighborhood development alone without careful consideration of the "mission benefit" of colocation first can have a profoundly negative consequence for non-profit organizations. At the inducement of neighborhood leaders, non-profits can feel compelled to move to locations that do not enhance their ability to deliver on mission. To borrow a phrase from the movie Field of Dreams - if we build a new community services center they will indeed come. Unfortunately, they may come for the wrong reasons and the project is likely to be unsustainable.
