The District should develop neighborhood-specific parking strategies and enforce its laws against double parking in order to reduce the frequent Sunday clashes between church congregates and neighborhood residents over sparse spaces, a task force recommends.

After four months of work, the task force of religious, community and government leaders suggested using existing policies and tools — angled parking, median parking, private garages, shuttle services, valet, carpooling and staggered worship hours — to relieve the problem. It said each neighborhood must work with the government to design a strategy.
