(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 Portland cement concrete in thicknesses required by the Codified Ordinances of the City of Seven Hills.
(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, asphalt 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.
(Ord. 69-2005. Passed 7-11-05.)
(c) Driveways, turnarounds, and parking areas whether new or replacement shall not be placed nearer than five (5) feet to any lot line on lots with greater than forty (40) foot frontage. For replacement of existing driveways that serve detached garages, where the distance between the house and the property line is less than 15 feet, this code shall permit the placement of a maximum 10 foot wide driveway to encroach on the 5 foot setback requirement provided the provisions of paragraph (d) are met.
(d) Driveways closer to a lot line than 10 feet shall be tapered from the outside edges to the centerline to form a "vee". This "vee" shall run the full length of the driveway. The minimum taper shall be one-eight (1/8)inch per foot. In lieu of the "vee", the Building Commissioner may authorize the installation of a curb at least 4" wide and 4" high on the edge of the driveway to control and direct the flow of water. This curb shall run the full length of the driveway. (Ord. 14-2012. Passed 2-27-12.)
(e) Where brick pavers are used, a proper base and base material must be used to establish a stable foundation. Drainage shall be provided to minimize settling or heaving.
(f) Excavation and Base. For light traffic areas excavate 5" to 6" where the pavers are to be laid. 3" to 4" will be the #9 crushed and compacted 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. The base and pavers combined equal 10". Proper compaction of sub-grade and base are mandatory.
(g) Edging. A substantial edge or curbing is required to retain the patio or driveway and to minimize “creeping” and 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 Commissioner.
(h) Sanding. Fine silica sand or mason sand shall be sweep into the joints of the pavers. This “sanding” locks the pavers in and tightens the entire surface. Sweep off the excess sand and hose patio off with water. Let dry and repeat this sanding process.
