C. 
Preparation of subgrade. All soft spots shall be compacted with a power roller weighing not less than 10 tons. If the base cakes up and moves under the roller, the spongy, soft area must be removed and replaced with a suitable material and rerolled until it compacts firmly without movement under the roller. The base shall be shaped to conform to the finished grade of the roadway.
D. 
Storm drains.
(1) 
All roads shall be properly drained and sufficient culverts and catch basins installed, except that, at the crest of a grade, no portion of any road shall drain in one direction a distance of more than 250 feet without catch basins on both sides of the road.
(2) 
Culverts shall be of sufficient size to handle a normal maximum amount of water from the area drained. All drainage pipe shall be reinforced concrete and at least 15 inches in diameter, with a minimum of three feet of cover, except as directed by the City Engineer.
(3) 
Where the contours of lots adjacent to the road are above the road and where subsurface drains exist and where concentrated water from driveways exists, creating icy surfaces on the roadway, the installation of storm drains across the entire area is required, voiding the two-hundred-fifty-foot exception.
(4) 
Drainage rights through lots shall be at least 20 feet wide, and all drainage to at least 200 feet away from the road shall be piped and covered. Headwalls of concrete, fieldstone or rubble masonry at the ends of pipe shall be three feet below the flow line and a minimum distance of three feet on all sides of the pipe in a vertical plane. Highway posts or guardrails shall be installed where necessary.
E. 
Sewers, mains and laterals.
(1) 
All sanitary sewers, storm sewers, water and gas mains must be installed prior to spreading the gravel course on the roadway. This includes sanitary sewer, water and gas main laterals which must be installed to at least three feet inside of the property line on each lot.
(2) 
It is the responsibility of the developer to notify the Director of Public Works that the subgrade is ready for a check of elevations. These elevations must be checked before gravel may be spread.
F. 
Gravel course. Gravel shall be subject to the inspection and approval of the Director of Public Works.
(1) 
The gravel shall be spread in a course of such depth that, after rolling has been completed, it shall be not less than six inches in depth when compacted.
(2) 
The gravel shall be wetted, if necessary, and rolled with a power roller weighing not less than 10 tons, and wetting and rolling shall be continued until the gravel is thoroughly compacted and the surface conforming to the grade of the roadway.
(3) 
The developer shall notify the Director of Public Works that the gravel course is completed and ready for inspection. No stone may be spread until this stage of construction has been approved by the Director of Public Works or his authorized agent.
G. 
Crushed stone base.
(1) 
One and one-half inches of crushed stone shall be applied, and the same shall be rolled to a thickness of four inches with a power roller weighing no less than 10 tons.

A filler shall be applied consisting of stone dust or a sharp clean sand in sufficient amounts to fill the voids in the course stone, and the same shall be thoroughly wetted, rolled and swept until voids are completely filled.
(3) 
The finished stone grade shall be [three inches] below the finished grade of the roadway.
(4) 
The developer shall notify the Director of Public Works that the stone course is completed and ready for inspection. No bituminous concrete material may be applied until this stage of construction has been approved by the Director of Public Works or his authorized agent.
H. 
Bituminous surface.
(1) 
Three inches of bituminous concrete shall be applied to the stone base. Said bituminous concrete may be applied in two courses, each 1 1/2 inches in depth.

Excavation.
(1) 
Soft and yielding materials from walk and driveway areas that exist within the confines of the legal lines of the street right-of-way shall be removed.
(2) 
Sidewalk area to eight inches below the finished grade shall be excavated and backfilled with four inches of gravel base, and four inches of monolithic two-thousand-five-hundred-pound concrete shall be placed on the same. Ten inches below the finished grade for driveways shall be excavated and backfilled with four inches of gravel base, and six inches of monolithic three-thousand-pound concrete shall be placed on the same.

A. 
Excavation. Any existing sidewalk or driveway shall be removed to the required depth below finished grade. All softyielding material shall be removed and replaced with suitable material.
B. 
Gravel bases of six-inch depth, after compaction, shall be placed between wooden forms on line and grade, allowing two inches for the placing of bituminous concrete.
