A. 
Environmental Management Districts may consist of one or more of the following overlay districts: Wetlands and Watercourse (W) District, Hillside Management (HM) District and Ground and Surface Water Protection (WP) District. These districts were created to provide regulations for certain special aspects of land use and development as they pertain to public safety, environmental protection and the preservation of scenic and cultural resources. An Environmental Management District shall function as an overlay zone and shall be used in combination with the base zoning districts. If there is any conflict between the requirements of the overlay zone and the base district, the more restrictive requirement shall apply.
B. 
In considering any special permit, site plan, project development plan or subdivision plan, the Planning Board shall, to the maximum extent practicable, maintain the areas delineated in an Environmental Management District as perpetual open space, directing allowable development into those areas not mapped within the district.
[Amended 6-20-2018 by L.L. No. 2-2018]
Environmental Management Districts shall be designated by means of the following methods, which may be used alone or in any combination:
A. 
By showing additional boundary lines and zone designations on the Official Zoning Map.
B. 
By using a separate Environmental Management District Overlay Map(s).
C. 
By describing Environmental Management Districts and regulations in the text of this article.
A. 
Purpose and intent. The purpose and intent of the Wetlands and Watercourses (W) Overlay District is to implement programs and policies of the Master Plan and Chapter 144, Freshwater Wetlands, of the Code of the Town of Putnam Valley, as they relate to preserving resources for flood protection, erosion control, wildlife habitat, pollution treatment, open space, groundwater and surface water quality, recreation and other benefits associated therewith.
B. 
Applicable regulations. The law regulating and controlling activity in and around freshwater wetlands, watercourses and water bodies is Chapter 144, Freshwater Wetlands, of the Code of the Town of Putnam Valley.
A. 
Purpose and intent.
(1) 
The purpose and intent of the Hillside Management (HM) District is to implement the programs and policies of the Master Plan, as they relate to protecting designated ridgelines and steeply sloped areas from erosion and maintaining the natural character and amenity of hillsides and ridgelines as a scenic resource of the town.
(2) 
In reviewing plans for development in hillside areas and along designated ridgelines, the Planning Board shall act to ensure the attainment of the following objectives:
(a) 
The preservation of natural topographic features and appearances by means of land sculpturing so as to blend any manmade or manufactured slope into the natural topography.
(b) 
The retention of major natural skyline profiles so as to avoid abrupt changes in grade.
(c) 
The retention of major natural topographic features, such as drainage swales, steep slopes, watershed areas, floodplain, view corridors and scenic vistas.
(d) 
The preservation and enhancement of prominent landmark features, such as natural rock outcroppings, prominent trees and plants, other areas of special natural beauty and stone walls and structures.
(e) 
The design and arrangement of building sites, utilizing increased lot sizes, greater setbacks and setback variations and reduced residential densities on steeper terrain so as to limit the extent of grading alterations.
(f) 
The utilization of clustered sites and buildings in areas with extreme topographical features so as to reduce grading alterations on slopes.
(g) 
The utilization of varying setbacks, building heights, innovative building techniques and compatible building forms and materials which serve to blend all buildings into the terrain.
(h) 
The utilization of building designs, locations and arrangements which serve to avoid a continuous intrusive skyline effect and which afford view, privacy and protection.
(i) 
The preservation and introduction of plants so as to protect slopes from soil erosion and minimize the visual effects of grading and construction on hillside areas.
(j) 
The utilization of driveway and road designs and improvements which serve to minimize grading alterations and harmonize with the natural contours and character of the hillside.
B. 
Applicability of regulations. The provisions of this section shall apply to all steeply sloped areas within the Town. For the purpose of this section, "steeply sloped areas" shall mean all properties in the Town which have a slope of 20% or more on any existing or proposed parcel, or portion of a parcel, or portion of a parcel proposed for development. The law regulating and controlling activity in a Hillside Management (HM) District is Chapter 155, Soil Erosion and Sediment Control, of the Code of the Town of Putnam Valley.

D. 
Special use permit. The uses and structures permitted in the Hillside Management (HM) District subject to the approval of a special use permit shall be as permitted in the underlying base district.
E. 
Development requirements. Prior to the issuance of a grading permit or a building permit or the approval of a subdivision or development approval plan or site plan for any parcel of land located within a Hillside Management (HM) District, the applicant shall submit development plans to the Planning Board.

Purpose and intent. The protection of the Town's lakes, ponds, reservoirs, wetlands, streams, drinking water, and watershed areas from surface water and groundwater contamination is essential to the proper maintenance of the quality and quantity of water in the Town and surrounding communities. It is, therefore, necessary to protect these areas from development encroachment, erosion and water pollution from surface or subsurface runoff.
[Amended 6-20-2018 by L.L. No. 2-2018]
B. 
Applicability of regulations. These regulations shall apply to all structures, parcels of land, and uses identified as Aquifer Protection Zones, Flood Zones, and/or Watershed Areas on the December 12, 2006, Ground and Surface Water Protection (WP) District Map, a copy of which map is on file with the Town Planning Department and the Town Clerk, and all areas within the City of Peekskill and New York City watershed areas.
[Amended 6-5-2002 by L.L. No. 5-2002; 6-20-2018 by L.L. No. 2-2018]
