(a) Proposed earth moving activities and storm water management practices shall be planned, designed and executed as required by this regulation and as required by the Land Development Regulations, Geauga Soil Sediment Pollution Control Regulations, Ohio Department of Transportation Location and Design Manual Vol. Two (Drainage Design) (Chapters 1101 and 1103 through 1110), the Comprehensive Plan, Chapter 901 (Street Regulation) where applicable, Chapter 929 (Storm Sewer Regulation) and such other adopted regulations and master plans of the Municipality as may be applicable. The referenced design standards shall include such future amendments thereto as may hereafter be adopted by the promulgating agency.
(b) All storm water management practices and any temporary or permanent erosion control practices shall be in accordance with the Municipal specifications, which except as may otherwise be provided herein, shall be the requirements set forth in the Geauga Soil Sediment Pollution Control Regulations.
(c) Easements and Rights-of-Way.
(1) Drainage Ways. Where a development project is traversed by a drainage way, channel or stream, a storm water easement or drainage right of way conforming substantially with the lines of such watercourse shall be provided. The easement, or right of way, shall be a minimum of forty (40) feet wide (exclusive of required lot area) for open channel waterways.
(2) Storm Sewer Easements. Storm sewer easements, or rights of way, shall conform to the requirement of Chapter 929 (Storm Sewer Regulations).
(3) Public Uses. Sites for public drainage ways, receiving waterways and other public uses may be required by the Approving Authority under the provisions of Section 1161.05(d)(3) (Easements and Rights of Way).
(d) Topography and Grading for Streets. When the development contains multiple lots and/or building sites it shall be planned and designed so that as many lots and building sites as possible will be above the street grade.
(1) Drainage. Development projects shall be designed to take every advantage of natural grades so that the land can be satisfactorily drained without excessive grading.
(2) Grading for streets shall be in accordance with the requirements of this regulation and S.U. & P.S. Chapter 901 (Street Regulations).
(3) The floor elevation of each building shall be established in proper relation to the surrounding grade, the driveway and the street. The lot shall be graded so that water drains away from each building at a minimum grade of two percent (2%). Grading shall be adjusted so there will be no abrupt grade changes in the required front yard or along side lot lines.
(4) The grading of blocks and lots shall be in accordance with the standards of the Municipality and may use any of the following grading systems:
A. Where there is a ridge along rear lot lines, and the lots drain to the street.
B. Where parts of all lots drain to a swale, or ditch along rear lot lines.
C. Where there is a cross slope, the drainage onto adjoining properties shall be skillfully controlled.
D. Where the land is relatively flat and adequate drainage must be formed.
E. Or a variation of the above conditions.
(5) The slopes of earth terraces shall not exceed a ratio of 2 ½ to l. If a retaining wall exceeds three (3) feet in height, a hedge, fence or railing shall be provided along the higher side thereof.
(6) All new buildings shall be constructed so that the elevation of the lowest floor shall be above the calculated 100 year water surface elevation of any adjacent natural or manmade open drainage way or flood zone designated on the Flood Insurance Rate Map (Federal Emergency Management Agency) (See Codified Ordinance Chapter 1323, Flood Damage Reduction.
(e) Natural Features. Trees, topsoil and other natural resources shall be preserved and utilized in the development project. In areas subject to earth moving activity the topsoil shall be stripped, stockpiled separately, and used in the finish grading and landscaping of the development project. As many existing trees as can be reasonably utilized in the final development plan shall be retained. No material change in grade shall be made within the diameter of the tree crown. When practical, existing trees shall be transplanted from areas subject to earth moving activity to locations within the development where they can be utilized.
