In all cases where curbs and/or sidewalks are constructed, the developer and/or contractor constructing them shall mark thereon the location of the sewer and water connections with the proper letter "S" and "W".
(Ord. 40-1962. Passed 5-28-62.)
(a) Any new allotment and/or subdivision proposed and/or commenced in the City shall contain provisions for the construction and installation of Portland concrete cement sidewalks therein. For all sidewalks constructed on corners in any new allotment and/or subdivision in any use district in the City, ramps must be installed pursuant to Federal law specifications to accommodate persons using wheelchairs. However, such allotment and/or subdivision shall be serviced by sanitary sewer facilities. Such sidewalks shall be constructed and completed within a two-year period from the time that construction of other required improvements commence within such subdivision. When the construction of homes within such subdivision is completed in less than two years and less than two sublots on each side of the street remain unimproved with house construction, or eighty percent of the house construction is completed, the developer shall, in either case, construct such remaining sidewalks in order to assure safe pedestrian travel within such subdivision.
(Ord. 29-1982. Passed 6-28-82.)
(b) The following specifications and requirements shall and are determined to be minimum requirements for sidewalks to be constructed in the City:
(1) Materials. All the materials used in constructing concrete walks shall comply with the following specifications.
Portland cement (air entraining), ASTM C-175;
Premoulded fibre expansion joints, ASTM D-5440
(2) Grading. Except as shown otherwise on the construction plans, grading shall include all excavation required to permit the construction of the proposed walks to the designated lines and grades.
A. Excavation. Except as otherwise ordered or shown on the construction plans, excavation at the elevation of the finished grade of the work shall extend six inches beyond each edge of the walk and then on a slope of one vertical to one and one-half horizontal. The cost of all excavation for a total depth of the full thickness of the proposed slab plus one and one-half inches shall be included in the price paid for walk complete in place. Excavation shall include the removal of all earth, roots and material of every description within the limits of the proposed work, except the removal of concrete and reinforced concrete.
B. Fill. Material excavated at one point on the project may be used for fill at another point if acceptable to the Engineer.
Filling shall extend at least one-half foot beyond each side of the walk unless otherwise ordered or permitted. Side slopes shall be trimmed to a slope of one vertical to one and one-half horizontal, except as otherwise ordered by the City Engineer.
Filling shall be made sufficiently in advance of walk construction to allow for settlement. The fill material shall be thoroughly compacted by tamping or rolling or by both, so as to produce a solid, dense subgrade.
(3) Construction. Except as otherwise directed, concrete walks shall be of one course of concrete.
(Ord. 987. Passed 5-8-61.)
A. Walks. Walks shall be four inches in thickness, except at driveways where the walks shall be six inches thick with wire mesh.
(Ord. 52-78. Passed 11-13-78.)
B. Concrete. Concrete for walks shall be proportioned as shown in the following table, using one inch maximum size aggregate and air entraining Portland cement:
Approx. Weight Pounds Per Sack of Cement | Approx. Volume Cu. Ft. Per Sack of Cement | ||||||
Max. Water Gals. Per Sack | Min. cement Sacks Per Cu. Yd. | Real Mix | Maximum Size Aggregat | Fine | Course | Fine | Course |
7 | 5.6 | 1-4.49 | 1" | 235 | 330 | 2.35 | 3.80 |
C. Placing concrete. Foundation beds shall be sprinkled immediately prior to depositing of concrete. Concrete, when mixed, shall be rapidly deposited in the work, and any concrete not in final position within thirty minutes after completion of the mixing shall not be used. Concrete shall be continuously deposited between bulkheads to a uniform thickness and to the full depth and width of the walk. The concrete, after being placed, shall be thoroughly compacted and brought to the proper pitch and grade with a template or straight edge. No concrete showing segregation of materials shall be deposited in the work.
(4) Cutting slabs. Immediately prior to the finishing of the surface, the walk shall be cut into slabs not longer than six feet on any one side. The joints shall be cut through the full thickness of the walk. The joints shall be formed by a cutting tool or other means satisfactory to the Engineer. The markings in the surface of the work at these joints shall not be more than one-fourth inch deep. All edges shall be rounded with an approved edging tool to a radium of one-fourth inch.
(5) Surface finish. The finish of the walk shall immediately follow the placing and compacting of the concrete. Unless otherwise ordered, a finish produced by rubbing with wood floats will be required. In the compaction of the freshly placed concrete, care shall be exercised that the concrete is worked only sufficiently to properly imbed the coarse aggregate and to produce concrete uniform in appearance, density and composition. The surface shall be free from depressions or inequalities. The application of dry cement to hasten drying of the surface is prohibited.
(6) Curing and protection. Immediately after the concrete has been properly placed and finished as heretofore specified, a white membrane curing compound meeting the requirements of Section M-10:25 of the State of Ohio Department of Highways Construction and Material Specifications, dated January 1, 1959, shall be applied uniformly by means of an approved pressure spray distributor at the rate of one gallon to each two hundred square feet of surface, and it shall be so applied that the concrete surface is completely coated and sealed at one application. After the surface has been coated, it shall be protected from all and abrasive action from any source. The contractor shall erect suitable barricades and take adequate precautions to keep all traffic or other operations off the newly-laid walks for a period of not less than forty-eight hours from the completion of construction. No walks will be accepted where foot marks, depressions or other irregularities exist.
(7) Expansion joints. Prepared strips of premoulded fibre expansion material shall be one-half inch in thickness and of sufficient width to extend the entire depth of the concrete and shall be placed in such a manner that the joint will be filled to within one-half inch of the finished surface of the wale and shall be constructed at intervals of not greater than fifty feet, unless otherwise ordered. Joints shall also be placed where the walk abuts curbing or other lateral walks and along the building line where the walk is laid full width from the curb to the building or other structures, or as otherwise ordered. The edges of all joints so placed shall be rounded as hereinbefore specified.
(Ord. 987. Passed 5-8-61.)
(c) The supervision and inspection of any sidewalks laid in the City shall be under the direct control of the Building Commissioner. (Ord. 15-1977. Passed 5-23-77.)
(d) A maintenance bond in the amount of ten percent (10%) of the total estimated cost of the sidewalk improvement, as estimated by the City Engineer, shall be posted by the contractor, developer or builder charged with the responsibility for the construction of the sidewalk installations to assure the satisfactory workmanship of the sidewalk installation. The bond shall run for a period of three years after the completion of the construction and installation of sidewalks. (Ord. 42-1983. Passed 11-28-83.)
(a) Driveways for New Dwellings. All driveways for new dwellings constructed in the City after the effective date of this section shall be Portland cement concrete or brick pavers of equal or greater strength than Portlamd cement concrete in thicknesses required by the Codified Ordinances of the City of Seven Hills.
(Ord. 105-1992. Passed 1-11-93.)
(b) Replacement of Existing Driveways. Replacement of existing gravel, aggregate, brick or concrete driveways replaced in the City of Seven Hills after the effective date of this section, shall be Portland cement concrete, asphaltic concrete or brick pavers of equal or greater strength than Portland cement concrete in thickness equal to Portland cement concrete required by the Codified Ordinances of the City of Seven Hills. Where brick pavers are used, a proper base and base material must be used to establish a stable foundation.
(1) Excavation and Base. For light traffic areas excavate 5" to 6" where the pavers are to be laid. Three to 4" will be the #9d crushed limestone material and 2-3/8" for the pavers laid on top. The base and pavers combined will equal 5" to 6".
For drives or heavy traffic areas. Excavate 10" where pavers are to be laid. Place 5" of #57 limestone (3/4") in the excavated area. Place 3" of the #9d crushed limestone on top of the #57. This combination will ensure proper drainage. The base and pavers combined equal 10". Proper compaction of subgrade and base are important to successful installation.
(2) Edging. An edge should be used to hold the entire patio or driveway together. Some typical edges include landscape timbers and various curbing edges such as plastic, steel, or aluminum which must be approved by the Building Board.
(3) Sanding. Sweep fine silica sand or mason sand into the joints of the pavers. This “sanding” locks the paver in and tightens the entire patio. Sweep off the excess sand and hose patio off with water. Let dry and repeat this sanding process.
(Ord. 22-1995. Passed 7-10-95.)
(c) Concrete Usage; Quality. Any and all concrete used for the purposes set forth in this section shall:
