A. Permit Required: All persons desiring to build cement sidewalks abutting any lot within the city limits shall first obtain a written permit therefor from the engineer, which permit shall be issued at a fee of ten dollars ($10.00). (Ord. 15, 4-8-1908; amd. 2001 Code)
B. Cement Sidewalks: All sidewalks hereafter constructed within the city shall be built of cement and according to the specifications prescribed in subsection D of this section.
C. Building Supervision: The building of all cement sidewalks shall be under the direction and control of the city engineer. (Ord. 15, 4-8-1908)
D. Specifications:
1. Width: All cement sidewalks hereafter built shall be five feet (5') in width, except on Gold and Silver Avenues, between Railroad Avenue and Hemlock Street, and on Pine Street, between Gold and Silver Avenues, which shall be of a width of ten feet (10'), and on Spruce Street between Gold and Silver Avenues, which shall be of a width of eight feet (8'). (Ord. 43, 2-1-1909)
2. Specifications: Such sidewalks shall be built in accordance to the following specifications:
a. Stakes shall be set by the direction of the engineer to define the line of one edge of the walk with a grade mark thereon to indicate the top of the walk at said lines. The transverse slope of the walks shall be one-eighth of an inch (1/8") per foot and shall be determined by such means as said engineer shall direct.
b. The sidewalk shall be graded to a width designated by said engineer for the entire length, including all wings and curbings, on a well-packed subgrade, which shall be satisfactory to said engineer and must first be inspected and accepted by him.
c. Upon this subgrade a pavement of the following description shall be placed: a layer of portland cement concrete not less than four inches (4") deep, well rammed and compacted, and a wearing surface of portland cement mortar one inch (1") thick.
d. All materials shall be of good quality and must be approved by the engineer. The gravel used for the concrete shall not exceed one and one-half inches (11/2"), and shall be of the best quality, sharp and clean and free from dust, loam and other foreign matter.
e. The cement used shall be portland cement of a good quality.
f. The water used shall be fresh and free from earth, dirt or sewage.
g. The concrete shall consist of one part in volume of portland cement, three (3) parts sand and four (4) parts gravel.
h. The cement and sand in the specified proportions shall be thoroughly mixed dry in a tight box or on a platform with shovels or hoes until no streaks are visible; water shall then be added in sufficient quantity to produce a mortar of the desired consistency, and the whole thoroughly mixed until a homogeneous mass is produced.
i. The mortar, prepared as hereinafter specified, shall be spread upon a platform, the proper quantity of gravel, after having been thoroughly wetted, shall then be spread over the mortar and the mass thoroughly turned over not less than three (3) times and until every piece of gravel is completely coated with mortar. Water shall be added by sprinkling during the process of mixing, if required to secure a better consistency.
j. All surfaces on or against which concrete is laid shall be cleaned and dampened by sprinkling with water just previous to placing the concrete.
k. The concrete shall be evenly spread upon the foundation, as soon as mixed, in a layer in such depth that after having been thoroughly compacted with rammers, it shall not be in any place less than four inches (4") thick, and the upper surface of it shall be parallel with the proposed surface of the completed pavement.
l. The slab or flag divisions shall be formed by cutting the concrete clear through as soon as laid, and the space made by the cutting tool shall be immediately filled with dry sand and well rammed.
m. Concrete shall not be mixed in larger quantities than is required for immediate use and no batch shall be larger than can be made of one barrel of cement with the proper proportions of sand and gravel.
n. The wearing surface shall be composed of one part in volume of cement to two (2) parts of sand.
o. The cement and sand in specified proportions shall be mixed dry on a platform or in a tight box until no streaks are visible. Water shall then be added in sufficient quantities to produce a mortar of the desired consistency, and all being turned and mixed until a homogeneous mass is produced.
p. The mortar, while fresh, shall be spread over the concrete base, before the latter has reached its first set, in such quantities that after being thoroughly manipulated and spread over the concrete it will make a layer one inch (1") thick conforming to the required grade and cross section. It shall be smooth and present a neatly finished surface.
q. The surface shall then be cut in flags, the markings to be made directly over the joints in the concrete and cut clear through the wearing surface, with edges nicely turned, so, also, the edges at each side of walk shall be nicely turned.
r. The pavements shall be kept moist and protected from the elements and travel until thoroughly set. Mortar or concrete that fails to show a proper bond or fails to set after, in the opinion of the engineer, it has been allowed sufficient time, shall be removed and material of proper quality put in its place. Wood frames or molds must be left in place until the cement sets perfectly and to the satisfaction of the engineer. (Ord. 15, 4-8-1908)
