These are engineering design plans for Jackson Drive, located in the Borough of Brookhaven, Delaware County, Pennsylvania, prepared by Catania Engineering Associates, Inc. The documents include a site plan, profile plan, and detail sheet for a road/infrastructure project involving storm sewer and utility infrastructure. The plan includes technical specifications for precast concrete inlet structures, street trench restoration, and pipe bedding and backfill details. The design drawings are dated 08/12/2025 and provide technical specifications for concrete strength, reinforcing steel requirements, material specifications, and installation guidelines for various infrastructure components including inlet tops, storm sewer pipes, and street restoration techniques.

The technical drawings provide detailed engineering specifications for construction, including concrete strength requirements (4,000 PSI in 28 days), reinforcing steel yield strength standards, and precise dimensional details for precast concrete structures. The design includes specifications for street trench restoration with layered materials including asphalt wearing courses, binder courses, and base concrete, as well as detailed bedding and backfill requirements using AASHTO #67 clean crushed stone. The project appears to be a municipal infrastructure improvement focusing on drainage and utility infrastructure along Jackson Drive, with meticulous engineering standards for construction materials and installation methods.
