Hydraulics, Hydrology and Drainage/Flood Control


The PEC Drainage and Flood Control team offers recent and extensive drainage planning, design, and construction experience. Due to our large municipal client base, we have addressed a wide array of drainage problems, particularly inadequate drainage capabilities following significant rainfall and flooding across Louisiana. From minor road side ditch culvert traffic challenges to major drainage basin improvement strategies, PEC designs and implements drainage plans and improvements tailored to meet the financial capabilities of each community.

 

Our experience includes all aspects of drainage planning:

  • Hydraulic models with software capable of evaluating up to 100 year storm events.

  • Drainage basin, watershed and runoff definition, and flood evaluations

  • Related mapping and water surface elevation

  • Proposed drainage improvement preparation to meet proposed water surface elevations

  • Construction cost estimate preparation

  • Improvement prioritization and schedule planning

  • Environmental and implementation concern resolution

  • GIS and CADD drawing preparation for integration and compatibility with existing programs and systems

 

PEC has conducted over 30 Flood Hazard Evaluations, as well as FEMA Flood Insurance, bridge, and associated drainage basin hydraulic studies, which are all relevant components to a Drainage Master Plan. We have been involved in preparing over 40 Drainage Master Plans and drainage basin planning assessments, including LA DOTD bridge hydraulic studies and large tract airport drainage assessments for LA DOTD Office of Highways and many parish and local governments throughout southern Louisiana.

 

This experience entails all elements of drainage work projects:

  • Field reconnaissance

  • Environmental assessments and permitting

  • Hydraulic studies and analysis

  • Utility relocations and upgrades

  • Preliminary engineering

  • Preliminary and final designs, plans, and specifications

 

Each of our Drainage Project Managers offers over 20 years’ experience in varied hydraulic programs for the infrastructure design of road and highway drainage projects and site planning. Drainage projects are routinely designed in-house for PEC’s state, parish, and local community clients.

 

Drainage design services include:

  • Comprehensive drainage master plans

  • Hydraulic basin studies

  • FEMA flood insurance studies

  • Flood hazard evaluations

  • Road drainage design

  • Airports drainage planning requirements

Our engineers follow a phased, financially feasible approach to efficiently and effectively solve drainage and flooding control problems, one project at a time.
