(a) The specific purpose and intent of this regulation is to regulate building and land use within riparian zones that would impair the ability of these areas to:
(1) Reduce flood impacts by absorbing peak flows, slowing the velocity of floodwaters and regulating base flow.
(2) Assist in stabilizing the banks of watercourses to reduce woody debris from fallen or damaged trees, stream bank erosion, and the downstream transport of sediments eroded from watercourse banks.
(3) Reduce pollutants in watercourses during periods of high flows by filtering, settling, and transforming pollutants already present in watercourses.
(4) Reduce pollutants in watercourses by filtering, settling and transforming pollutants in runoff before they enter watercourses.
(5) Provide watercourse habitats with shade and food.
(6) Reduce the presence of aquatic nuisance species to maintain a diverse aquatic system.
(7) Provide riparian habitat to a wide array of wildlife by maintaining diverse and connected riparian vegetation.
(b) This regulation has been enacted to protect these services of riparian areas by providing reasonable controls governing building and land use within a riparian zone along designated watercourses in the City.
(Ord. 75-15. Passed 7-13-15.)
(a) This regulation shall apply to all zoning districts in the City as defined in the most recent version of the Zoning Resolution.
(b) This regulation shall apply to all lands that are within the jurisdiction of the City and that border designated watercourses as defined in this regulation.
(Ord. 75-15. Passed 7-13-15.)
For the purpose of this regulation, the following terms shall have the meaning herein indicated:
(a) "Avon" means City of Avon, its designated representatives, boards, or commissions.
(b) "City Engineer" shall mean the City's Engineer, its consulting engineer or engineering firm, any engineer or engineering firm hired by the City to perform work for the City on any given project or any designee of one of the above, e.g., a Building Inspector designated to perform stormwater inspections.
(c) "Damaged or diseased trees" means trees that have split trunks; broken tops; heart rot; insect or fungus problems that will lead to imminent death; undercut root systems that put the tree in imminent danger of falling; lean as a result of root failure that puts the tree in imminent danger of falling; or any other condition that puts the tree in imminent danger of being uprooted or falling into or along a watercourse or on to a structure.
(e) "Ditch" means a stream of water in a definite channel, having a bed and sides or banks and discharging itself into some stream or body of water, whether natural or man-made, and whether stream flows continually or not. The two types of ditches (major and minor) are defined by a map on file at City Hall.
(f) "Federal Emergency Management Agency (FEMA)" means the agency with overall responsibility for administering the National Flood Insurance Program.
(g) "Ohio Environmental Protection Agency" means the organization referred through this regulation as the "Ohio EPA".
(h) "100-Year Floodplain" means any land susceptible to being inundated by water from a base flood. The “base flood” is the flood that has a 1% or greater chance of being equaled or exceeded in any given year. The 100-Year Floodplain shall be defined by the Federal Emergency Management Agency maps for the City.
(i) "Ordinary high water mark" means the point of the stream bank to which the presence and action of surface water is so continuous as to leave an area marked by erosion, destruction, or prevention of woody terrestrial vegetation, predominance of aquatic vegetation, or other easily recognized characteristic. The ordinary high water mark defines the bed of a watercourse.
(j) "Riparian area" means naturally vegetated land adjacent watercourses that, if appropriately sized, helps to stabilize stream banks, limit erosion, reduce flood size flows, and/or filter and settle out runoff pollutants, or performs other functions consistent with the purposes of this regulation.
(l) "Soil and Water Conservation District" means an entity organized under Ohio R.C. Chapter 1515, referring to either the Soil and Water Conservation District Board or its designated employees.
(m) "Soil-disturbing activity" means clearing, grading, excavating, filling, dumping, grubbing, stripping, or other alteration of the earth's surface where natural or human-made ground cover is destroyed and which may result in, or contribute to, erosion and sediment pollution.
(n) "Top of bank" means the location of the upper edge of the active ditch above which the water spreads into the overbank areas on either side of the ditch.
(o) "Waste Water Treatment Plant (WWTP)" means a facility at the end of the sanitary collection system which processes the influent waste, and discharges water to a receiving system, treated to the standards of the Ohio Environmental Protection Agency (EPA).
(p) "Watercourse" means any brook, channel, creek, river, stream, or ditch having banks, a defined bed, and definite direction of flow, either continuously or intermittently flowing.
(q) "Watershed" means the total drainage area contributing stormwater runoff to a single point.
(r) "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, including swamps, marshes, bogs, and similar areas. (40 CFR 232, as amended)
