Construction plans for subdivisions, site development and public improvements must include steps needed to prevent and mitigate urban erosion and urban sedimentation. The developer shall submit plans and/or a report, prior to construction, which indicate the mitigating and controlling measures appropriate to the site. The Highway Superintendent and Town Engineer shall review this plan. The Highway Superintendent or Town Engineer shall have the authority to require that the approved plan shall be implemented.
A. 
Vegetative control measures include:
(1) 
The planting of grasses, legumes, trees and shrubs. The developer shall select species that are adapted to the site and purpose of planting. A planting guide should be consulted which lists the most common and important area species of grasses, woody plants and legumes that may be used for controlling erosion and sediment.
(2) 
Topsoiling and slope stabilization (mulched anchoring) for establishment of the grasses and legumes; grassing waterways and outlets; ditch and channel bank seedings, jute and sod. The developer shall apply needed ground cover on exposed soils within 15 to 30 days of exposure, except on areas where final construction will begin within 30 days. The developer shall stockpile topsoil to apply on sites as required for establishing vegetation.
(3) 
Protection of trees against damage from construction grading and landfilling.
B. 
Burning of vegetative cover will not be allowed, unless by county permit.
A. 
Land grading shall be in accordance with the approved plan. The plan shall limit the grades of slopes so that plants may be easily established.
B. 
Suitable side slopes which are not greater than two to one shall be maintained for slope stability.
C. 
Benches, berms, terraces or ledges, temporary and permanent, shall be constructed as necessary across sloping land to reduce the length and grade of a steep slope.
D. 
Diversion ditches or channels and ridges shall be constructed to intercept surface runoff as necessary.
E. 
Grassed waterways or outlet swales shall be constructed to maintain nonerosive velocities as required.
F. 
Siltation, debris or sediment basins shall be constructed to trap runoff waters during construction, prior to entering a stream, creek, pond, lake, swamp or other environmentally sensitive or protected body of water.
G. 
Grade stabilization structures shall be constructed from earth, pipe, concrete, masonry, steel, aluminum, wood or sod. These structures shall be used as required to safely convey water, reduce grades, stabilize downcutting or change the direction of flow of water.
H. 
Any detention structure, retention structure or impoundment pond shall be constructed to store runoff waters and release same at a rate which will prevent flooding and erosion. The pond may have earthen dams, spillways, pipe outlet structures, overflow weirs or ditches to control the outflow.
I. 
Gabions and mattresses (compartmented rectangular containers made of heavy galvanized steel wire woven in twist patterns and filled with stone), may be used to support vegetation growth, to mitigate erosion and ice flows, as revetments for embankment protection, as weirs in basin designs or channel lining in ditches.
J. 
Temporary silt fences and staked hay (straw) bale berms shall be used to contain sediment on site and allow the passage of runoff waters.
K. 
Finished culvert end sections shall be installed on all pipe ends to prevent scouring and undercutting. Rip-rap shall be placed beyond the end section on both the sides and bottom slopes of the drainageway.
L. 
Protective slope materials shall be utilized and they include straw or hay anchored in place with asphalt emulsion, stapled-down jute or polypropylene mesh, wood chips and continuous filament fiberglass.
M. 
Temporary erosion and siltation control measures shall conform to the requirements of the United States Department of Transportation, Federal Highway Administrative Guidelines, New York State Guidelines for Urban Erosion and Sediment Control, or Dutchess County SCS Soil Erosion and Sediment Control Guidebook.
A. 
The developer shall take reasonable measures to control fugitive dust emissions on haul roads or roads under construction.
B. 
Dust control should be by means of continuous watering or other means approved by the Highway Superintendent or the Town Engineer.
