Harper Houf Peterson Righellis Inc.

Civil Engineering | Transportation

HHPR collaborates with a diverse group of public and private clients to deliver top-level civil engineering, planning, landscape architecture, surveying and project management services. We deliver services with an emphasis on transportation, hydrology, water resources, and land use planning. We have the capability to take a project from conception and master planning, through design and construction. Senior-level professionals perform the majority of all technical tasks. By taking this hands-on approach, an experienced professional always has in-depth and intimate knowledge of each project. This improves overall project management, reduces the opportunity for costly oversights and delays, and allows HHPR to provide effective and efficient service.
