The developer shall establish and clearly mark on the site the limits of the road right-of-way and easements, the center line and grades of the road pavement and the location and elevation of drainage and drainage structures in accordance with the approved plans. Such markers shall be maintained at the developer's expense until the construction of all required improvements within the right-of-way limits has been completed, inspected and approved by the Town Superintendent of Highways.
A. 
The developer shall clear the entire area within the limits of:
(1) 
The road right-of-way, exclusive of trees designated by the Town to remain.
(2) 
Stream channels and ditches.
(3) 
Easement areas.
B. 
All roots and stumps shall be grubbed, excavated and removed from the above areas. No roots and stumps shall be buried on any portion of any lots without the expressed permission of the Town Engineer and the Town Zoning Administrator.
A. 
The developer shall complete the shaping of the road right-of-way, stream channels and ditches and easement areas to the line and grade as shown on the approved plan and as otherwise may be directed by the Town Superintendent of Highways. All unsuitable or unstable materials shall be completely excavated and removed from the right-of-way and all rock or boulders larger than six inches in diameter shall be excavated at least eight inches below the finished subgrade of road pavement, drainage or drainage structures, curbs and sidewalks.
B. 
Where fills are necessary to complete the required line and grade or to back fill trenches or other excavation, the materials incorporated in the work shall be acceptable to the Town Superintendent of Highways and Town Engineer and shall be placed in layers not exceeding eight inches in depth, each layer to be thoroughly compacted by rolling with a vibratory roller, sheepsfoot, pneumatic-tired or padded-wheel roller or by impact rammer or vibrator equipment in areas inaccessible to power rollers. All compaction shall continue until the fills are firm and unyielding. Refer also to § 199-26.
C. 
The areas between the edge of the pavement and the right-of-way line must be graded and seeded in order to prevent erosion. This may include temporary seeding if determined necessary.
D. 
The rough grade of the road pavement, curb and sidewalk areas shall be completed to within one inch above or below finished subgrade as shown on the approved cross section of the right-of-way improvement.
E. 
Earth shoulders and flow line of ditches, gutters, culverts and catch basins shall be maintained in satisfactory condition at the developer's expense at all times during the course of construction of the subdivision and until such time as the Town Board has accepted dedication of the right-of-way.
A. 
The width of the trench in which drainage pipe is placed shall be sufficient to permit thorough tamping of the backfill under the haunches and around the pipe. Where rock in either boulder or ledge formation is encountered, it shall be removed below grade and replaced with suitable materials in such a manner as to provide an earth cushion having a thickness under the pipe of not less than eight inches, and where there are excessively heavy fills over the top of the pipe, the Town Superintendent of Highways may specify that an earth cushion up to 1/2 inch in thickness per foot of fill be placed over the top of the pipe. In no case shall the top of any drainage pipe be less than 18 inches below the finished grade of the pavement. Where soft, spongy or other unstable soil is encountered at the grade established, all such unstable soil under the pipe and for a width of one diameter on each side of the pipe shall be removed and replaced with run-of-bank gravel or other acceptable material. In all cases the bed shall be thoroughly compacted and shall provide a firm foundation for the pipe.
B. 
Pipe shall be laid to true line and grade on the prepared bed of the trench. All connections for making field joints in corrugated metal pipe shall consist of corrugated metal bands so constructed as to lap on equal portions of each of the culvert sections to be connected. All joints in making field connections of reinforced concrete pipe shall be filled with portland cement mortar or shall use watertight gaskets (ASTM C443 - latest revision).
C. 
Backfilling of trenches shall be done in accordance with § 199-16B.
D. 
Any additional drainage facilities not shown on the approved plan and which may be ordered by the Town Superintendent of Highways shall be constructed by the developer at the developer's expense and in accordance with these specifications. In all such cases the Town Engineer's review and approval is required. In cases where the Highway Superintendent and Town Engineer are unable to agree on the need for such changes or additions, the matter(s) shall be brought before the Town Board.
E. 
Refer also to §§ 199-23 and 199-26 for additional requirements relative to culvert excavations, installations, and backfilling.
