Blue Marsh Lake, Bernville Protective Works. Design Memorandum Number 13 Schuylkill River basin. Tulpehocken Creek, Pennsylvania
Abstract
Construction of protective works for the Borough of Bernville is necessary to relieve that community of flooding hazards created by the construction of the Blue Marsh Dam and Lake project. Below elevation 300 at the proposed project site lies a relatively uninhabited low-lying area which serves as an overbank flood plain. Many commercial and private improvements, as well as a utility substation and sewage treatment facility, lie above elevation 300. Therefore, elevation 300 was fixed as the upper allowable flooding elevation from project-induces flooding. Four alternate plans--and several options under each plan--were investigated and priced to determine the most economical way to provide effective flood protection acceptable to local officials/utility owners. The alternative selected called for diverting both the upper and middle tributaries of the Schylkill River through culverts to Northkill Creek. This plan substantially reduced the size of the pond area and the anticipated use of part of this excavated material to construct the levee.
