March 15: Alterra’s Broad and Washington plans | Voluntary street sweeping | Deregulating garage businesses

Mayor Jim Kenney is doubling down on the idea of bringing back street sweeping services, but only for neighborhoods who accept alternate-side parking. It’s still unclear what the administration will consider an acceptable threshold of neighborhood support. “I’m not forcing people to have a clean street,” he told Andrew Thompson at NBC, “We should clean the city at least twice a year with a massive clean-up, which we’re planning. But in the meantime, on a bi-monthly or monthly basis, I’m not going to have people screaming and yelling that they don’t want to move their car from one side of the street to the other because it’s such an inconvenience, when they do it in Manhattan twice a week.”

Katie Colaneri looks at the Philadelphia Coalition for Affordable Communities’ idea for a developer impact fee to support the Housing Trust Fund. The fee could generate between $3-12 million a year for submarket development, but the report prepared for PCAC by Econsult Solutions found it could also depress new construction. “On the higher end, a fee of $4.80 per square foot could “reduce market rate activity” by as much as 14 percent,” writes Colaneri.
