Public Works Engineering

HHR has extensive experience in well permitting, new community water systems, state permitting for water extensions, booster pumps, storage tanks, troubleshooting, and development of standards and specifications. We have designed sewer pump stations, sewer line extensions, and coordinated environmental permitting. As Certified Floodplain Managers, we have experience with floodplain engineering related to FEMA’s National Flood Insurance Program (NFIP). We can assist a community with floodplain mapping and revisions, ordinance revisions and program updates, flood mitigation planning, and Community Rating System (CRS) implementation. HHR can address drainage problem areas by designing improvements to storm sewers, detention ponds, water quality, culverts and bridges. We can provide master planning for drainage improvements. We have assisted communities with NPDES Ph 2 implementation and establishing a local stormwater utility to fund stormwater improvements. We are qualified and experienced in erosion and sediment control design, and are instructors in Georgia’s Erosion and Sedimentation Control certification program.
