Structures that are not attached to the dwelling that are of wood or steel platform framed construction are permitted to have foundations that extend to not less than 18 inches in depth below finished grade, provided all of the following apply:
(a) The maximum dimension of the structure does not exceed 24 feet in length or width.
(b) The maximum height of the structure does not exceed 15 feet when measured to the highest point of the roof.
(c) The structure is located a minimum distance of ten feet from the dwelling it serves.
(d) The foundation bears upon soil capable of supporting all imposed loads.
(e) The foundation is constructed of solid concrete poured at least 12 inches wide continuously around the perimeter of the structure.
(f) The foundation is poured monolithically with a minimum four-inch nominally thick concrete floor slab that is reinforced with steel mesh weighing not less than 40 pounds per 100 square feet or equivalent reinforcement that is turned down continuously into the footing.
(g) No sheds, porches or other structures are attached increasing the structure's length or width beyond 24 feet or height beyond 15 feet.
(h) A six-inch wide concrete curb is constructed around the perimeter of the structure that is a minimum of eight inches above the adjoining grade.
(Ord. 91-2009. Passed 4-20-09.)
(a) All disturbed ground areas shall be graded to provide positive drainage in conformance with Chapter 921 and the regulations of the Director of Public Service.
(b) Except where approved by the Director of Public Service, a drain shall be provided in the driveway area. The drain and its accompanying sewer shall conform to the requirements of Chapter 921 and regulations of the Director of Public Service.
(c) Where a driveway is replaced in its entirety or a detached building in excess of 180 square feet is constructed, the construction shall comply with Chapter 921 as relates to storm water drainage.
(Ord. 91-2009. Passed 4-20-09.)
(a) Applicability. The following constitute minimum standards which apply to hard surface pavement installations located outside of the public rights-of-way. The pavement design shall be based on soil support values and projected traffic volumes but not less than the following standards. All paving materials and installations shall conform to the State of Ohio Department of Transportation Construction and Material Specifications, published by the Ohio Department of Transportation (ODOT).
(b) Portland Cement Surfaces.
(1) Sub-grade preparation. Treatment of installation area shall include removal of all topsoil, loam, roots, and undergrowth; loose, soft or excessively wet soils shall be replaced with premium fill and leveled prior to placement of base material.
(2) Base preparation. Concrete shall be placed on a base course to a depth of three inches for residential and six inches for commercial or industrial uses comprised of ODOT 304 aggregate base.
(3) Concrete. The mixture of Portland cement concrete shall conform to ODOT item 499 class C-modified. The mix shall be air entrained per specification and otherwise modified to achieve a minimum 28-day flexural strength of 650 psi. Or, any Portland cement concrete mix which is air entrained and has a minimum compressive strength of 3,500 psi shall constitute an acceptable alternative. Concrete shall be poured to a depth of four inches for residential and six inches for commercial or industrial uses.
(4) Reinforcement optional. The concrete may be installed using a ten gauge welded wire fabric reinforcement with a six inch by six inch maximum opening, or fiber reinforced concrete which complies with ASTM C1116 standard specifications is also an acceptable reinforcement option.
(5) Surface finish. Surface treatment shall be of a medium broom finish or better.
(c) Asphaltic Concrete Surfaces.
(1) Sub-grade preparation. Treatment of installation area shall include removal of all topsoil, loam, roots, and undergrowth; loose, soft or excessively wet soils shall be replaced with premium fill and leveled prior to placement of base material.
(2) Base preparation. Asphaltic concrete shall be placed on a base course to a depth of six inches comprised of ODOT 304 aggregate base.
(3) Asphaltic concrete shall be comprised of a base course of two and one-half inches of ODOT 448 Type II asphaltic concrete and a surface course of ODOT 448 Type I asphaltic concrete leveled to a depth of one and one-half inches.
(d) Water permeable surfaces.
(1) “Permeable pavement” shall be defined as an area paved with material that permits water penetration into the soil. Permeable pavement may consist of any porous surface materials which are installed, laid or poured.
(2) Alternative surfaces engineered to promote water percolation shall comply with the following:
A. Sub-grade and sub-base preparation shall be installed per manufacturer specifications or per engineer’s specifications.
B. Exposed surface materials are to be reviewed by the City Engineer based on performance expectations similar to that of traditional Portland cement or asphaltic concrete.
