"Aquatic Resources"means wetland waters (i.e. vernal pools, swales, freshwater marsh, other seasonal wetlands, etc.), non-wetland waters (i.e. ponds, lakes, streams, rivers, drainages, ditches, etc.), and riparian (i.e. mixed riparian scrub, mixed riparian woodland, etc.).
"Aquatic Resources Delineation"means identifying the amount and boundaries of Aquatic Resources, including wetlands, using U.S. Army Corps of Engineers (USACE) mapping standards and USACE minimum standards for delineations.
"Avoidance"means avoiding the permanent and/or temporary impact altogether by not taking a certain action or parts of an action.
"Compensatory Mitigation"means the restoration (re-establishment or rehabilitation), establishment (creation), enhancement, of aquatic resources for the purposes of offsetting unavoidable adverse permanent and/or temporary impacts which remain after all appropriate and practicable avoidance and minimization has been achieved.
"Compensatory Mitigation Ratio"means the amount of Compensatory Mitigation that must be provided to offset an acre or fraction thereof of permanent and/or temporary impact.
"Director"means the Director of the Department of Community Development.
"Enhancement"means the manipulation of the physical, chemical, or biological characteristics of an aquatic resource to heighten, intensify, or improve a specific aquatic resource function(s). Enhancement results in the gain of selected aquatic resource function(s), but may also lead to a decline in other aquatic resource function(s). Enhancement does not result in a gain in aquatic resource area.
"Establishment"means the manipulation of the physical, chemical, or biological characteristics present to develop an aquatic resource that did not previously exist at an upland site. Establishment results in a gain in aquatic resource area and functions.
"Habitat"means the place or environment where a plant or animal naturally lives and grows (a group of particular environmental conditions), and as defined in the South Sacramento Habitat Conservation Plan. Habitat may be occupied (i.e. individuals or a population of species are or have recently been present) or unoccupied.
"Impact."See "Permanent Impact" and "Temporary Impact."
"Minimization"means to reduce permanent and/or temporary impacts by limiting the degree or magnitude of the action and its implementation.
"Open Water"means a permanent water impoundment that is mostly free from masses of underwater vegetation at very shallow depths.
"Permanent Impact"means the permanent loss of an Aquatic Resource resulting from the adverse effects of grading, filling, excavation, dredging, or changing of drainage of an Aquatic Resource.
"Plan Area"means that portion of the unincorporated County that is south of U.S. Highway 50, east of the Sacramento River levee and County Road J11, west of the Sacramento County line with El Dorado and Amador Counties, and north of the Sacramento County line with San Joaquin County, as depicted in Figure 1, "Plan Area."
"Re-establishment"means the manipulation of the physical, chemical, or biological characteristics of a site with the goal of returning natural/historic functions to a former aquatic resource. Re-establishment results in rebuilding a former aquatic resource and results in a gain in aquatic resource area and functions.
"Rehabilitation"means the manipulation of the physical, chemical, or biological characteristics of a site with the goal of repairing natural/historic functions to a degraded aquatic resource. Rehabilitation results in a gain in aquatic resource function, but does not result in a gain in aquatic resource area.
"Riparian"means a transitional area between terrestrial and aquatic ecosystems, which is distinguished by gradients in biophysical conditions, ecological processes, and biota, typically adjacent to perennial, intermittent and ephemeral streams, lakes, and estuarine-marine shorelines.
"Setback"means an upland, wetland, and/or riparian area that protects and/or enhances aquatic resource functions associated with wetlands and streams from disturbances associated with adjacent land uses.
"Stream"means a perennial, intermittent, or ephemeral course of water that has a bed and bank and with a definable ordinary high water mark.
"Temporary Impact"means the grading, filling, excavation, dredging, or changing of drainage of an Aquatic Resource where the Aquatic Resource is restored to pre-construction contours and elevations after construction, and revegetated, as appropriate.
"Vernal Pool"means a type of seasonal wetland habitat that is characterized by a specific set of physical parameters and a unique assemblage of highly specialized endemic plants and animals; a seasonal body of standing water that typically forms in the spring from direct precipitation, with occasional contributions from other sources, dries out completely in the hotter months of summer, and refills in the autumn; pools free of fish that provide important breeding habitat for many terrestrial or semi-aquatic species such as Branchiopods, frogs, and salamanders.
"Watershed"means a drainage basin that is defined by a 10-digit hydrologic unit code as defined by the Federal Standard for Delineation of Hydrologic Unit Boundaries.
"Wetland"means those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include freshwater marsh, vernal pools, swales and similar areas.
