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.
