Flood Control Systems

Flood Protection Feasibility Analysis: Feasibility analyses can be performed to screen a number of conceptual alternatives leading to the best solution meeting the project objectives.  A “feasibility” evaluation addresses the (1) economic suitability, (2) constructability, (3) satisfying the primary project objectives, and (4) compatibility with future watershed projects.

Flood Control Facility Engineering / Design: Our staff has extensive understanding of hydraulic principles associated with flood control systems and the different empirical methods for analysis to ensure that the system will function correctly.  Our background in hydraulic analysis includes detailed hydraulic design for a variety of hydraulic structures which range from dams, open channels, river control structures, culverts, storm drains, energy dissipaters, spillways, revetments, river training, levees, drop structures, desilting facilities, and intakes structures.  Detailed hydraulic modeling for water surface profile analysis can be performed for underground systems, prismatic open channels, and variable natural floodplains or riverine studies.  Extensive technical resources have been accumulated regarding hydraulic design analysis procedures for different applications and include familiarity with numerous criteria and design publications. We have specialized analytical tools for the analysis of specialized hydraulic structures which include 3-D modeling and variety of unique empirical equations and process to evaluate the hydraulic operation.

Facility Improvement Plans and Specifications: One of the primary strengths of PACE is the specialization of improvement plan preparation developed for stormwater and flood control systems.  Over half of the stormwater engineer workload is associated with design/plan preparation for installation of flood control facilities.  This extensive project application experience has provided a tremendous wealth of background in specific format for plan requirements and typical agency needs related to plan information.

Urban Drainage Facilities: PACE’s background in urban drainage systems includes a wide variety of specialized underground and open channel facilities that require unique hydraulic analysis techniques.  PACE maintains an extensive library of technical drainage guidance manuals from almost every state in the nation that facilitates providing background to different types of systems typically utilized.

Specialized Construction Materials and Techniques: Developed applications for the use of unique construction materials on flood control facilities and “state of the art technology”, which has included soil cement, geotextile and geosynthetic systems, vinyl sheet piles, precast box sections, concrete gunite arches, HDP systems, underground systems, precast water quality treatment systems, articulating block systems, metal box sections, reinforced earth systems or MSE bank stabilization.

Emergency Flood Protection Repair Design / Planning: Experienced in guiding the planning and participating in the emergency response for flood damage repair and emergency flood protection repair.  The fast track emergency response team is experienced in the formulation of cost effective solutions through planning, coordination, and construction of remediation and restoration measures. We understand processes, issues, and regulations important to the variety of federal, state, city, tribal, private and corporate representatives involved in active, changing, and time sensitive emergency repairs.
