Drummond Carpenter, PLLC

Provides stormwater management and urban runoff solutions from concept through post-construction analysis. The practice helps municipal, educational, and non-profit clients implement resilient site designs.

• Conceptual Design and Community Planning

  Facilitates collaborative community engagement and site planning to identify sustainable design opportunities.

• Rain Garden Design and Construction

  Designs and implements localized bioretention systems to manage and filter runoff.

• Green Infrastructure Hydrologic Modeling

  Simulates runoff reduction and watershed benefits using advanced hydrologic models.

• Urban Retrofit Performance Monitoring

  Measures and evaluates the post-construction hydraulic and water-quality performance of green installations.

Delivers comprehensive site planning, flood mitigation, and watershed management solutions. Engineering designs focus on balancing the requirements of the natural and built environments.

• Flood Control and Drainage Analysis

  Analyzes storm events and drainage patterns to design mitigation infrastructure that reduces flooding risks.

• Water Quality and TMDL Compliance

  Develops solutions to address total maximum daily load regulatory mandates and treat water quality impairment.

• Erosion Control and Stream Restoration

  Designs natural channel stabilization and erosion prevention measures to restore degraded stream systems.

• Civil Site Plan Development

  Designs physical site layouts, grading, and utility connections for public and institutional facilities.

Develops and applies mathematical models to simulate complex environmental processes. Quantitative assessments support water availability, pollution forecasting, and regulatory decision-making.

• Groundwater Flow Modeling

  Simulates subsurface flow and contaminant transport to protect drinking water aquifers.

• Surface Water Hydrodynamic Modeling

  Models surface runoff, lake systems, and river hydrodynamics to evaluate flooding and water quality.

• Model Calibration and Sensitivity Analysis

  Refines simulations using field-collected data to ensure model accuracy and predictive reliability.

Investigates, characterizes, and cleans up sites affected by hazardous substances. Remedial strategies target metals, chlorinated chemicals, petroleum hydrocarbons, and other pollutants.

• Contaminated Soil and Groundwater Investigation

  Performs field sampling and site characterization to delineate the extent of contamination.

• Remediation System Design and Implementation

  Engineers active and passive cleanup systems to restore environmental media to regulatory standards.

Provides specialized technical advisory and modeling services for nuclear waste management facilities and Department of Energy programs.

• Radiological Dose Prediction

  Evaluates potential exposure pathways and models radionuclide migration to estimate potential doses.

• Waste Containment and Barrier Modeling

  Assesses the long-term performance of containment structures and engineered barriers designed for nuclear storage.
