Water Resource Management Services

Chastain-Skillman, Inc. offers a wide array of integrated water resource management services. Our Engineers and Scientists utilize state of the art technologies to develop the tools and solutions necessary to maintain a thorough understanding of your water resource assets. We can evaluate your system, identify system deficiencies, and provide holistic solutions to enhance your system.


Know your System

Watershed Management Planning

Chastain-Skillman’s experts understand the need to develop holistic, cost effective management strategies to get the most out of limited resources. We strive add value into every step of our processes. In our watershed management plan we develop a complete inventory of your stormwater infrastructure, provide analysis of existing watershed conditions and geo-spatial visualization of flood risk. Additionally we offer water quality assessments, hydrologic and hydraulic modeling, maintenance evaluations and system inspections.  

Infrastructure Inventory/Maintenance Evaluations/Inspections

A critical part of our comprehensive watershed management plan is to develop a complete digital infrastructure inventory and evaluate the current condition of your stormwater system. Our professionals will digitally document the spatial location and condition of every system element to provide system managers the information to operate and maintain the stormwater system. Remediation efforts will be developed and prioritized to outline a cost effective maintenance strategy.

Hydrologic and Hydraulic Modeling

Our water resource engineers will develop highly detailed stormwater models to provide cost effective evaluation of the functionality of a storm water system, under a variety of scenarios. We utilize the latest technology to  reduce the cost of model development and provide visualization of flood risk. Our digitally based, geospatial approach provides the information necessary to maintain a comprehensive understanding of your system’s functional capacity.

Water Quality Assessments

Our water quality assessment of your lakes and streams will identify deteriorating water quality due to excess pollutant loading or biological/ecological imbalances. We provide specific management strategies to Improve water quality.20140525_155613 (1)


Know your risk

  Flood Risk Assessment

Flooding caused by stormwater runoff results in billions of dollars of property damage every year, not to mention displacement of citizens from their homes and loss of irreplaceable processions. Our predictive stormwater modeling and flood risk mapping will identify the functional limitations of your stormwater system, under a variety of conditions, allowing communities to prepare for and mitigate flood risk before disaster strikes.

FEMA Flood Risk Mapping

Due to recent Federal legislation, the cost of flood insurance and floodplain impact mitigation is expected to increase significantly. Outdated or incorrect flood mapping can cause unreasonable flood insurance premiums. Our floodplain management services can provide a highly detailed and up to date flood risk maps, resulting in a substantial reduction of flood insurance premiums year after year.


Know your Options

Stormwater Improvement Projects

Our stormwater design engineers can provide the full suite of services to take your stormwater retrofit project from conceptual design and feasibility analysis to construction in the most cost effective manner possible.

Low Impact Stormwater Infrastructure

Let our stormwater design professionals help reduce the foot print of your stormwater infrastructure and add value to your land with low impact development retrofits such as rain gardens, bio-swales, pervious pavement, sub-surface storage and multi-use facilities. Our solutions will meet regulatory requirements while improving the aesthetics and recreational benefits of your property.

Know your Responsibilities

Regulatory Permitting Support

Our experts bring the knowledge and tools needed to navigate the strict regulatory environment associated with management of any stormwater system. We provide the full range of National Pollution Discharge Elimination System (NPDES) support to meet your regulatory obligations including system inspections, negotiations, and annual reporting.

 Stormwater systems discharging stormwater to a water body with an established Total Maximum Daily Load (TMDL) are required to take steps to reduce contribution of pollutants We understand the daunting mandate a TMDL  posses and can provide the support necessary to meet this mandate..

The goal of the Environmental Resource Permitting program is to prevent adverse impacts to the existing stormwater system.  Projects which potentially modifying the existing system hydrology or hydraulics require an ERP. Our Engineers can streamline the regulatory process to get your project off the ground.
