Restoration Monitoring
Montgomery County's Department of Environmental Protection protects and enhances aquatic ecosystems through stormwater management and stream restoration. The County is committed to its natural resources and complying with the County's National Pollution Discharge Elimination System (NPDES) Municipal Separate Storm Sewer (MS4) Permit.
Monitoring the success and/or failures of the various restoration projects is crucial in determining how future projects will be designed and built to ensure a positive impact on the aquatic ecosystem.
DEP conducts monitoring beyond the baseline requirements set forth by the regulatory agencies to ensure all the goals of the projects are met. Various techniques are used to determine whether a restoration project is successful, partially successful, or did not meet the restoration goals.
| Restoration Goals | How Monitoring is Done to Evaulate Goals |
|---|---|
| Improve water quality |
Aquatic Communities: Benthic macroinvertebrates, fish & salamanders Qualitative In-situ water chemistry |
| Avoid introduction of new thermal impacts | Stream Temperature |
|
Reduce stream erosion and sedimentation Reduce erosive stream flows |
Quantitative habitat (stream morphology surveys) |
| Create vernal pool to catch overland flow and stormwater | Vernal pool |
| Reforest riparian zone | Botanical survey |
