Impervious surface

A church outside Philly is trying to build an expansion, but some neighbors are contesting a decision to allow the new construction. One of the sticking points is a complaint about the change in impervious surface:

Zoning hearing board chairman David Malinowski said the variances were justified. One of the variances allows the church to increase the percentage of impervious (hard pavement) surface on the five-acre property, from 22.3 to 31.5 percent. The other allows the continuation of some encroachments into front yards along Makefield and Sutphin roads.
