What is the "sewer envelope"?

The sewer envelope is depicted on the category maps as a boundary beyond which no community water and sewer facilities will be approved. The sewer envelope boundary is based on topography, existing sewer service areas, and proposed development density according to the Area Master Plans. The Sewer Envelope boundary was first established in 1994. The County Council reaffirmed the envelope boundary by adopting it as the template for the Rural Tier boundary adopted in the Adopted 2002 Prince George’s County General Plan. Although there are minor mapping differences, the Rural Tier and Sewer Envelope boundaries generally run concurrent.
