An Act amending Titles 8 (Boroughs and Incorporated Towns) and 11 (Cities) of the Pennsylvania Consolidated Statutes, in storm sewers and watercourses, further providing for authority of boroughs and for manner of financing work; providing for storm water management plans and facilities for incorporated towns; and, in watercourses, flood protection projects and storm water systems, further providing for establishing and changing watercourses, flood protection projects and storm water systems and for assessment of benefits and liens.

HB 990 amends Pennsylvania statutes to give boroughs and incorporated towns new authority over stormwater management. It requires municipalities to develop stormwater management plans and facilities, and allows them to charge fees based on property characteristics - particularly impervious surfaces like driveways, roofs, and pavement - which are presumed to benefit from stormwater systems. Property owners may qualify for fee exemptions or credits if they install approved stormwater facilities meeting "best management practices." The bill directly affects local governments (boroughs and incorporated towns) and property owners through new planning requirements and potential fees.
