A. 
Adoption. A map entitled "City of Saco, Zoning Map" and dated December 2, 2020[1] is hereby adopted as part of this chapter and hereafter shall be referred to as the "Official Zoning Map."
[1]
Editor's Note: The Zoning Map, which took effect 4-12-2021, and as subsequently amended, is included as an attachment to this chapter.
B. 
Exceptions. The Official Zoning Map shall be the final authority as to the boundaries of zoning districts, except in regard to the Shoreland Zoning Overlay Districts, which are more particularly described in Article VIII herein.
C. 
Copies of the Zoning Map. Representative maps which may be appended to this chapter are for reference only and shall not be construed to be the Official Zoning Map.
A. 
Uncertainty of boundaries. Where uncertainty exists with respect to the boundaries of the various districts as shown on the Zoning Map, the following rules shall apply:
(1) 
Boundaries depicted as approximately following the center lines of streets, highways, or alleys shall be construed to follow such center lines.
(2) 
Boundaries depicted as approximately following well-established lot lines shall be construed as following such lot lines.
(3) 
Boundaries depicted as approximately following municipal limits shall be construed as following municipal limits.
(4) 
Boundaries depicted as following shorelines shall be construed to follow such shorelines, and in the event of natural change in the shoreline shall be construed as moving with the actual shoreline.
(5) 
Boundaries indicated as approximately following the center lines of streams, rivers, canals, lakes, or other bodies of water shall be construed to follow such center lines.
(6) 
Boundaries depicted as following or measured from natural features such as the upland limit of wetlands or the limit of floodplains shall be construed to follow or be measured from the actual limit of the natural resource as located on the face of the Earth even if such location is at variance with the location shown on the Official Zoning Map.
(7) 
Where physical or cultural features existing on the ground are at variance with those shown on the Official Zoning Map, except as provided in Subsection A(1) through (6) above, or in circumstances where the items covered by Subsection A(1) through (6) above are not clear, the Board of Appeals shall interpret the district boundaries.
B. 
The district boundaries located on the Zoning Map represent the City of Saco's ordinance. In addition, areas along the Saco River are also governed by the Saco River Corridor Commission. Separate, and in some cases more restrictive, regulations exist for this area and must be consulted when development is contemplated.
C. 
Division of lots by district boundaries. Where a zoning district boundary line divides a lot, the regulations applicable to either lot may be extended up to 100 feet into the other lot.
The City is divided into the districts stated and described in this chapter and as shown by the district boundary lines on the Official Zoning Map. The district classifications are shown in Tables 3-1 and 3-2:

Portions of this district are sewered. It is intended that new land uses in this district are restricted to those that are compatible with the character of existing residential development.
(2) 
Location. The LDR District is located in four areas of the City, including:
(a) 
A 600-foot-wide corridor along Buxton Road/Route 112 to the west of Louden Road.
(b)

(2) 
Location. The HP Overlay District is located along Main Street, including portions of Route 1 and Route 9, and along Bradley Road/Route 112 and Beach Street/Route 9. The HP Overlay District includes areas shown on adopted Historic Preservation Map.
A. 
Saco River Corridor. The Saco River Corridor Commission has been established by the Maine Legislature to regulate development within in the Saco River Corridor. The Saco River Corridor includes all lands adjacent to the Saco River to a distance of 500 feet, as measured on a horizontal plane, from the mean high-water line of the river or to the edge of the 100-year floodplain if the floodplain extends beyond 500 feet, up to a maximum of 1,000 feet.
B. 
Activities within the Saco River Corridor are subject to the jurisdiction of both the City of Saco and the Saco River Corridor Commission (SRCC). Construction, development, and some other activities require approval from both the City and the Corridor Commission. Refer to Title 38 M.R.S.A §§ 951 through 969 for Saco River Corridor Act, and contact the Saco River Corridor Commission for applicable performance standards.
C. 
Activities within the Saco River Corridor must conform to the applicable City regulations as well as to the Commission's regulations.
D. 
To coordinate the review and permitting process, applicants or potential applicants should first determine if the proposed activity is allowed under the City's regulations. The applicant should then obtain a permit for the activity from the Saco River Corridor Commission. Once the SRCC permit has been obtained, the applicant should apply for City permits or approvals needed for the project. Obtaining a permit from the SRCC does not absolve the applicant of the requirement to obtain City permits and approvals.
