Boundaries of these districts are hereby established as shown on a map entitled "Zoning Map of Winslow, Maine," dated December 13, 2012, which accompanies and is part of this chapter. Such boundaries shall be construed to follow corporate limits; lot or property lines; center lines of streets, highways, alleys, easements, and railroad rights-of-way, or such lines extended; unless otherwise noted on the Zoning Map. Any zoning district boundary disputes will be decided by the Board of Appeals.
Vacation of public streets and alleys shall cause the land vacated to be automatically placed in the same district as the abutting side to which the vacated land reverts. A certified copy of the zoning map shall be adopted and approved with the text as part of this chapter and shall bear upon its face the attestation of the Chair of the Town Council and the Town Clerk, and shall be available to the public in the office of the Town Clerk.
When any amendment is made to any district boundary or other matter portrayed on the certified copy of the zoning map, the map shall be revised promptly after the amendment has been approved by the Town Council with an entry on the map indicating the number of the ordinance and the date it was adopted. The revised zoning map shall be signed by the Chair of the Town Council and attested by the Town Clerk. The current zoning map shall be kept in the office of the Town Clerk. Dimensional requirements pertain to all buildings, principal and accessory, unless specific statements indicate otherwise.

§ 300-43 Accessory dwelling units (ADUs); up to four additional dwelling units on a single lot.

The authorization of multiple dwelling units on a single lot, including the addition of accessory dwelling units and the conversion of existing accessory structures into ADUs, as outlined in Article III, Divisions 3 and 4 of this chapter, is permissible in zoning districts where these primary and conditional uses are allowed:
Single-family dwellings.
Two-family dwellings.
Multifamily dwellings.
New mobile homes outside a mobile home park.
Any addition of an ADU or conversion of an existing structure into an ADU must adhere to the same minimum dimensional requirements as a residential structure, as indicated in the tables within this article.
Additional dwelling units developed on a single lot are subject to the provisions of Article III, Division 4 of this chapter, as well as the minimum lot size requirements for the zoning district, as specified in the tables in this article.
The addition of any dwelling units (ADUs, additional dwelling units on a single lot, or affordable housing) will be subject to the provisions of Article III, Divisions 3, 4, and 5 of this chapter and must comply with the same minimum dimensional requirements for residential structures per the tables in this article for the zoning district in which they are constructed.

§ 300-44 High-Density Residential District.

Purpose. The High-Density Residential District includes predominantly built-up areas of Town that consist of existing residential structures on small lots and some municipal and educational uses such as schools, parks, playgrounds, churches and other public buildings.
The district is designed to protect and enhance the existing character, scale and uses already established in these areas. New construction, alterations and proposed changes of use shall be required to be consistent with the established residential character of the district.
Minimum dimensional requirements. All dimensions are minimum requirements unless otherwise indicated.

§ 300-46 Low-Density Residential District.

Purpose. The purpose of the Low-Density Residential District is to provide locations for new single-family residential housing in a rural setting adjacent to existing built-up areas of Town. This district is envisioned to have public water and sewer. These areas are established to attract new home construction that would otherwise be located in the more rural sections of the community. The goal is to provide ample areas that will supply future home buyers a setting in a rural environment, yet still close to the Town center. Agriculture and forestry and similar resource based activities are encouraged; however, some commercial, service and municipal uses are allowed in this district and any mixed use will have to blend into these residential areas.
Requirements to blend. To blend into the existing character of the neighborhood, all existing residential properties within 500 feet of any property line of a proposed nonresidential use shall be considered as neighborhood. The Planning Board and Code Enforcement Officer shall address the following items when reviewing a use or building permit application:
How different the uses are to each other.
Buffering with natural vegetation and/or structural requirements to help blend or disguise the proposed use.
Traffic and traffic control and parking.
Hours of operation, lighting and signage. (Hours may be limited depending on the proposed use.)
Sewage disposal: If private, the plan must include an additional area shown on the site plan for a replacement system dedicated to future subsurface waste disposal.
Stormwater management and snow removal.
Noise and odor control.
Outside storage of goods and materials on site must be buffered and not visible from any public way or abutting property.
Architectural compatibility: For those uses which require high visibility, the Planning Board may require additional public hearings and input from the neighborhood.
Minimum dimensional requirements. All dimensions are minimum requirements unless otherwise indicated.

§ 300-47 Mixed Use District.

Purpose. The Mixed Use District consists of many of the older sections of Town and contains a variety of residential, commercial, recreational, municipal and educational uses. Municipal water and sewer are available throughout most of the district. The character of the district is dominated by a dense development pattern with commercial uses dispersed among single- and multifamily residential homes. The existing mixed use development pattern shall be maintained by allowing a wide number of residential uses; allowing the expansion of existing nonresidential uses; and by allowing some commercial uses that are able to blend and exist in harmony with the character of the district.
Requirements to blend. To blend into the existing character of the neighborhood all existing residential properties within 500 feet of any property line of a proposed nonresidential use shall be considered as neighborhood, The Planning Board and Code Enforcement Officer shall address the following items when reviewing a use or building permit application:
How different the uses are to each other.
Buffering with natural vegetation and/or structural requirements to help blend or disguise the proposed use.
Traffic and traffic controls and parking.
Hours of operation, lighting and signage. (Hours may be limited depending on the proposed use.)
Sewage disposal: If private, the plan must include an additional area shown on the site plan for a replacement system dedicated to "future subsurface waste disposal."
Stormwater management and snow removal.
Noise and odor control.
Outside storage of goods and materials on site must be buffered and not visible from any public way or abutting property.
Architectural compatibility: For those uses which require high visibility, the Planning Board may require additional public hearings and input from the neighborhood.

§ 300-50 Seasonal Residential District.

Purpose. The Seasonal Residential District includes areas adjacent to Pattee Pond that are already divided into small lots and contain structures or are undeveloped. Most of the lots contain seasonal homes; however, there are some year-round dwellings and undeveloped parcels. The primary goal of the district is to maintain and improve the water quality of Pattee Pond by strictly regulating any increases in land use intensity and the expansion of structures and uses within the built-up areas around the Pond. The existing low intensity land use of seasonal homes and camps is allowed. Expansion of structures and uses, including conversion from seasonal to year-round dwellings, are subject to performance standards.

§ 300-51 Conservation District.

Purpose.
The Conservation District is the area within the boundaries of the Pattee Pond watershed as determined by Maine Department of Environmental Protection.
It is intended to be a rural area with limited commercial or industrial activity or other uses which would tend to adversely affect water quality. The district is generally restricted to low-impact development with special attention to the following areas:
Floodplains that make building or development difficult, costly or unacceptable.
Poor soil types not suitable for building or development.
Steep slopes or embankments that render building or development generally difficult, costly or unacceptable.
Significant wetlands that provide breeding and feeding habitat for waterfowl.
Natural sites of significant scenic or aesthetic value, historic sites and archeological sites.
Minimum dimensional requirements. All dimensions are minimum requirements unless otherwise indicated:

§ 300-52 Contract zoning.

Authority. In accordance with 30-A M.R.S.A. § 4352(8), as amended from time to time, property in the Town of Winslow may be rezoned by means of a process known as contract zoning.
Purpose.
It is the general purpose of this section to provide for the reasonable regulation of uses of land and structures where competing and incompatible uses conflict. In these special situations, in which traditional zoning regulations are inadequate, more flexible and adaptable zoning methods are needed to permit differing land uses and at the same time recognize the effects of change.
In considering a change in zoning for a particular property or group of properties, it may be determined that public necessity, convenience, or the general welfare require that provision be made to impose certain limitations or restrictions on the use or development of the property. Such conditions are deemed necessary to protect the best interests of the property owner, the surrounding property owners and the neighborhood, all other property owners and citizens of the Town, and to secure appropriate development consistent with the Town's comprehensive plan. The provisions of this section shall not exempt the use or development of any property from other minimum standards or requirements otherwise provided in this chapter, or as otherwise provided by law.
Definition. "Contract zoning" is the process by which the property owner, in consideration of the rezoning of his property, agrees to the imposition of certain conditions or restrictions not imposed on other similarly zoned properties.
Mandatory conditions. Any amendment to the boundaries of a zoning district adopted pursuant to this section shall:
Be consistent with the Comprehensive Plan of the Town of Winslow, as amended;
Be consistent with the existing and permitted uses within the rezoned district;
The request for contract zoning consideration must be initiated by the property owner;
Only include conditions and restrictions which relate to the physical development or operation of the property;
Be subject to an agreement executed by authorized representatives of both the property owner and the Town providing for the implementation and enforcement of all terms and conditions imposed and agreed to by the parties pursuant to this section.
Discretionary conditions. Any zone change adopted pursuant to this section may include reasonable conditions or restrictions such as, but not so limited to, the following:
Limitations on the number and type of authorized uses of the property;
Limitations on the height, exterior appearance and lot coverage of any structure or structures built on the property;
Increased or decreased setbacks and side yards for any structure or structures built on the property;
The installation, operation and maintenance of physical improvements for the convenience of the general public, including but not limited to off-street parking lots, traffic control devices, fencing, shrubbery and screening;
The creation, operation and maintenance of open space areas or buffer zones;
The dedication or conveyance of property for public purposes, including but not limited to, streets, scenic and conservation easements, parks and utility systems.
Procedure. All proposed amendments to this chapter being considered under this section shall be processed in accordance with this chapter and 30-A M.R.S.A. § 4352(8). If at all possible, the processing of the application under both shall be accomplished concurrently.
