The following ad hoc technical committees were convened to conduct research and make recommendations to the Steering Committee. Technical committees are made up of experts from within the Etowah watershed and staffed by researchers from the University of Georgia.
stormwater & better site design
The Stormwater/BSD technical committee developed a model stormwater management ordinance and site design guidelines for residential, commercial and industrial development that would minimize and mitigate impacts on the imperiled species covered by the HCP
The Runoff Limits program requires that in the most sensitive watersheds (determined based on studies of sensitive fish tolerances and the distributions of imperiled fish species) the volume of runoff from new development must match that of the site in an undeveloped, forested condition. For moderately sensitive watersheds and designated development nodes, the runoff limits are higher. The Runoff Limits Technical Committee is developing a design manual and training program to support implementation of the program.
erosion & sedimentation control
The Erosion and Sedimentation Control Technical Committee was convened to provide recommendations for improving E&S management as part of the Etowah Aquatic HCP.
Extensive grading can have serious consequences for aquatic species and habitat. The alteration of topography often makes erosion and sedimentation difficult, if not impossible, to control, and can result in post-construction stormwater management problems as well. The Grading Technical Committee developed a model grading ordinance intended to minimize the impacts of grading on the species covered by the HCP.
The Stream Buffer Technical Committee developed a model ordinance based on the Metropolitan North Georgia Water Planning District model stream buffer ordinance (which many Etowah jurisdictions must adopt in some form) with added provisions designed specifically to protect the imperiled species covered by the HCP.
The design, sizing and installation of culverts and bridges affects the imperiled aquatic species covered by the HCP. Many types of culverts can serve as physical barriers to fish movement, and can also have detrimental effects on stream shape and flow, altering habitat. The Road Crossings Technical Committee developed guidelines for the design of road crossings based on the ecosystem needs of the covered species.
The design and installation of utility crossings affects the species covered by the HCP. The Utility Crossings Technical Committee is developing guidelines for the design and installation of utility crossings based ont he habitat needs of the covered species.
The Conservation Subdivision Technical Committee developed a model conservation subdivision ordinance based upon that of the Metropolitan North Georgia Water Planning District.
water supply planning
The siting of water supply reservoirs affects the species covered by the HCP. The Water Supply Planning Technical Committee is researching ways to meet the region's water supply needs while protecting the viability of the covered species.
