<p>A developer, answering a request from a public agency, proposes to build a 119-unit residential building. Forty-eight of the units are to be affordable to low-and very-low-income persons. The project is a block from a light-rail station, and within a few minutes' walk of 100,000 jobs. It's in a neighborhood that's been environmentally studied and zoned for precisely this kind of infill residential development. Infill, transit-oriented, affordable: the project is a smart growth dream.</p>
