§ 220-34 General requirements.

Construction starting date.

Construction may not be commended until after a public hearing has been duly held on the particular subdivision map and the final map has been approved and filed with the County Clerk.

The developer must consult or notify the Planning Board's authorized representative not less than 24 hours before beginning any construction work that requires inspection in accordance with the site bond.

Building permits. Building permits shall not be issued by the Building Inspector before final action by the Planning Board and plat filed with the County Clerk, with the exception of those pertaining to model houses.

Model houses. After a public hearing and before final action by the Planning Board, the developer may secure building permits for model houses, subject to requirements and conditions as imposed by the Planning Board. In no event will a certificate of occupancy be issued until all improvements have been made, with the exception of landscape items. Separate performance bonds for all site improvements incidental to the site of each model house, including a proportionate share of off-site but related other improvements, shall be filed by the developer before any permit shall be issued for a model house.

Schedule of operations. The developer shall indicate, in writing, a schedule of operations prior to the start of construction to ensure the orderly procedure of the work.

Neatness. The developer, during the entire period of construction work, shall keep the site in a neat and orderly condition and shall immediately comply with any reasonable directives of the Building Inspector or Planning Board as and when issued.

Sanitary facilities. The developer shall provide sufficient and suitable conveniences, well secluded, constructed and maintained in conformance with the local, county and state sanitary laws, for use of all workmen employed on the site. On or before the completion of the work, the developer shall remove all of the temporary buildings and structures used for this purpose.

Traffic maintenance. The flow of traffic or the safety thereof on any public street or highway within the Village will not be restricted or endangered in any way by construction operations, equipment, vehicles or materials connected with the construction or sales' operations of a subdivision. The developer must provide off-street parking space for all vehicles used in construction or sales' operations. Equipment or materials may not be stored within the right-of-way lines of any public street or highway but shall be stored in an area protected by solid-type fence structure not to exceed eight feet in height.

Temporary roads. All roads within a development which are used by the contractors or others and which have not been surfaced must be suitably treated and maintained to minimize dust.

Temporary drainage. Rainfall runoff from developments during construction operations must be confined to the site unless an adequate stormwater drainage system exists. Methods of providing for temporary drainage and erosion control shall be approved by the Planning Board. Stormwater runoff disposal during construction onto existing roads, streets or private property is prohibited. All work shall conform to the soil erosion, sediment control and water retention policy of the Village.

Condition of construction equipment. Equipment used for site improvement work shall be of modern type and in sound operating condition and adequate for the purpose for which it is to be used and must conform to those laws, rules and regulations of the New York State Department of Motor Vehicles.

Developer's responsibility. The developer is responsible for keeping all roads, streets and private property free of debris and damage caused by construction operations or by stormwater runoff from the development site. Any damage so caused shall be immediately repaired by the developer at his own expense. If after due notice by the Village Clerk or Building Inspector or Planning Board, the developer does not proceed within 72 hours to make the necessary repairs or to remove the debris caused by his operations, the Village is empowered to take necessary corrective measures and the costs shall be paid by the developer. The developer shall comply with the New York State Manual of Uniform Traffic Control Devices (Maintenance of Traffic) and New York State Code 23 (Safety - Excavations).

[Added 1-22-1990 by L.L. No. 1-1990]

Undedicated roads remain the property and responsibility of the developer. However, upon issuance of the first certificate of occupancy in the development involving new or undedicated roads, the developer shall post a cash bond to cover estimated cost of snow plowing and sanding to be performed by the Village in the event that the developer shall fail to plow and sand the roads.

The purpose of this provision is to insure the public safety by maintaining access to residents in newly developed areas.
