The Capital Improvement Program (CIP) is responsible for the design and construction of the County's transportation infrastructure and the maintenance and rehabilitation of the existing infrastructure.

CIP construction  activities include new roadway construction, road widening, intersection improvements, sidewalk installation and repair, bridge construction and rehabilitation, traffic design and construction and may also include stormwater drainage infrastructure built in conjunction with a roadway or bridge. In 2008, the CIP engineers managed over $20 million in professional service contracts and construction projects.

Goals established for CIP activities include the following:

  • Ensuring that the improvement, construction, maintenance and rehabilitation of infrastructure provides the public with an acceptable and enhanced transportation network that takes into consideration access and mobility for citizens and the economic viability of business and industry.
  • Effective coordination with adjacent public jurisdictions, special districts and private entities on optimization of services and joint funding opportunities for construction projects.
  • Investigation of new and innovative ways to maintain, improve and fund transportation infrastructure needs.
  • Maximization and effective management of federal and state grant monies for bridge and roadway construction and rehabilitation projects.
  • Compatibility of traffic concerns and hydraulic/hydrology issues of a completed construction project with existing infrastructure and general compliance with County criteria.
  • Standards development for the Metropolitan Government Pavement Engineer's Council. The section is active in the lobbying efforts for federal earmark funds.

Key components of all CIP projects include preparing preliminary engineering and cost estimates, performing in-house design/engineering/construction project management, managing the consultant engineering components of various projects (design review of consultant plans, resultant contract negotiations and on-going budget reports), managing the construction of all authorized capital projects and acquiring necessary right-of-way for CIP projects. In addition, the section contracts its services to various metropolitan districts for capital project management and inspection, as well as other County departments (Open Space).
