(a) Proposed development shall comply, as much as is practical, to the following design guidelines:
(1) Upland sites shall be chosen for building locations. The presence of upland soils shall be verified by reference to the Summit County Soil Survey by the U.S. Soil Conservation Service.
(2) Normally isolated wetlands, which tend to fill, then overflow during floods. Flowage areas should be protected from incompatible development. Road construction across such areas shall be limited. Where construction does occur, roads should be constructed on pilings or with adequate culverts so as not to obstruct the flowage area.
(3) Runoff should not be discharges directly into open waters. Vegetated buffers, swales, vegetated watercourses, wetlands, catch basins and similar systems for detention, retention, treatment and percolation of runoff should be used as appropriate to decrease velocities, increase infiltration, and remove pollutants.
(4) Natural watercourses shall not be filled, dredged, cleared, deepened, straightened, stabilized or otherwise altered, except in cases of over-riding public interest.
(5) Intermittent watercourses, such as swales, shall be vegetated.
(6) Vegetated areas shall be retained in their natural state, along the banks of all natural watercourses, water-bodies, and wetlands. The width of the vegetated area shall be sufficient to prevent erosion, trap sediment and pollutants in overland runoff, and allow for periodic flooding without damage to buildings, roads, or other structures.
(7) Runoff from newly developed or redeveloped parking lots shall be treated or run through a filtering basin to remove oil and sediment before it enters receiving waters.
(8) Detention and retention areas shall be designed so shorelines are sinuous rather than straight to maximize shoreline length so as to increase growth of littoral vegetation. Care should be taken to avoid creating stagnant water areas.
(9) Detention and retention areas shall have maximum bank slopes of 4:1 so as to safeguard against personal injury, and to encourage growth of littoral vegetation.
(10) Although the use of wetlands for storing and purifying water is encouraged, wetlands should not be damaged by overloading beyond their limited capacity to serve these functions.
(11) Erosion should be minimized and sediment retained on the development site through the use of Best Management Practices as outlined in the publication "Rainwater and Land Development".
(12) The total or partial filling of any lake, pond, or other water body in existence at the time of enactment of this Code, shall be subject to permitting procedures of the U.S. Army Corps of Engineers, Ohio Department of Natural Resources, the Ohio Environmental Protection Agency and other appropriate regulatory agencies as well as the provisions for Environmental Impact Assessment in Section 1175.05 of these development regulations.
