In the Industrial district, buffer areas may not be reduced by modification or variance. For developed sites where an existing building is set back farther than the maximum allowed setback, additions to that building are intended to be set forward to meet the setback, however, where that would result in an inefficient site design or make the project unviable, the reviewing board may grant a waiver. In granting a waiver, the board must review alternatives and take into consideration the public interest to determine if a waiver is needed. Waivers should be the minimum amount needed to remedy the hardship. 75 ft minimum setback from shoreline all structures other than permitted piers, docks, marinas, dams, bridges, and other water-dependent uses; 50 ft minimum shoreline and 25 ft minimum stream buffers to be maintained in natural vegetative state Minimum shoreline frontage 100 ft (10) Any required side or rear setback area located within fifty (50) feet of a lot containing a dwelling not in a residential zoning district shall be maintained as a buffer area meeting the standards of the Design Lewiston Site Plan Review and Design Guidelines/Standards.

(17) For the purpose of determining compliance with front, rear and side setback requirements, an enclosed walkway connecting structures on abutting lots in the institutional-office (IO), whether it be underground, elevated or at grade, shall not be considered a structure but shall be considered a walkway. Similarly, awnings and canopies installed on lots in the institutional-office (IO) district that provide shelter from the elements, whether made of permanent or non-permanent material shall not be considered as structures and may extend into the front, side, and rear setback areas to the extent necessary to provide adequate shelter from the elements as long as the installation will not result in undue impact on adjacent properties, due to the placement of the awnings or canopies, location of service, parking or storage areas, or blocking of solar access, and shall in no way interfere with utilities or with the convenient and safe use of the sidewalk and street right-of-way by all pedestrians and vehicles, but in no case may the canopy be closer than two feet from the property line. (18) Existing lots of record having 150 feet or less of frontage on a street functionally classified as an arterial shall be limited to one point of vehicular access to the arterial to serve all development on the lot including the division of the lot into additional lots. ---PAGE BREAK--- APPENDIX A – ZONING AND LAND USE CODE ARTICLE XI. DISTRICT REGULATIONS Lewiston Code A XI:17 Existing lots of record having more than 150, but less than 500 feet of frontage on a street functionally classified as an arterial shall be limited to two points of vehicular access to the arterial to service all development on the lot including the division of the lot into additional lots. Existing lots of record having 500 feet or more of frontage on a street functionally classified as an arterial shall be limited to two points of vehicular access to the arterial for up to 1,000 feet of frontage, plus one additional point of access to the arterial for each additional 500 feet of frontage on the arterial or portion thereof.

Ground signs are encouraged to be pedestal type ground signs not exceeding eight feet in height. e. The following design standards are encouraged for any project subject to development review; however, may be waived by the appropriate reviewing authority due to site limitations and the nature of the development: Off street parking is to be located on the side and rear of buildings; Any new development or renovations shall generally relate in design features to the surrounding building, showing respect for the local context of Main Street, as seen from Holland Street to Montello Street; Gable or hipped roofs should be used to the greatest extent possible with any new development or renovations. Flat and shed style roofs are discouraged, unless architectural features are applied to minimize the roofs appearance from Main Street false fronts, parapets, etc.) Shared driveway entrances shall be encouraged with adjacent sites, in order to minimize curb cuts. Additional landscaping, buffering, and screening are encouraged to minimize views of parking areas from streets and abutting properties. (20) Where the side or rear setback area for uses other than residential is located within fifty (50) feet of a residential zoning district, a minimum fifty (50)-foot wide buffer area shall be maintained along the side and rear setbacks and a buffer provided in accordance with the buffer standards of the Design Lewiston Site Plan Review and Design Guidelines/Standards. In the Industrial district, buffer areas may not be reduced by modification or variance. (21) Reserved. (22) In areas where the existing buildings have an established uniform setback relationship to the street, any new building or modification to an existing building shall maintain this established relationship notwithstanding the setback provisions of that district. An established uniform setback relationship is deemed to exist when the distances between the front face of the building and the edge of the travel way in the adjoining street for the two adjacent parcels fronting on the same street on each side of the subject parcel are within five feet of mean of this distance for the four parcels.

DISTRICT REGULATIONS Lewiston Code A XI:19 (26) The required minimum lot area per dwelling unit for any residential use in the neighborhood conservation district shall be the average lot area per dwelling unit of impacted properties. The maximum number of dwelling units that can be placed on a parcel in the district shall be figured by the following procedures: The total lot area of all developed impacted properties shall be calculated. In determining the total area of the impacted properties, the tax records of the City of Lewiston shall be used unless the applicant or the owner of an impacted property presents definitive evidence to the contrary. The total number of legally existing dwelling units shall be calculated. The total lot area shall be divided by the total number of dwelling units existing on the impacted properties. This figure divided into the lot area of the subject parcel yields the total dwelling units which can be placed on the lot. If less than 50 percent of the impacted properties are in residential use, the minimum lot area per dwelling unit shall be the greater of: One thousand five hundred square feet per dwelling unit; or The minimum area derived by the procedure outlined above.

Waiver Requests Development Review applications shall meet Design District Overlay standards contained in this subsection, unless the appropriate reviewing authority grants a waiver request. Applicants shall provide written justification as to how the waiver request meets the following criteria. ---PAGE BREAK--- APPENDIX A – ZONING AND LAND USE CODE ARTICLE XI. DISTRICT REGULATIONS Lewiston Code A XI:33 There are extraordinary and exceptional conditions pertaining to the particular piece of property. For example, the waiver is justified because of topographic or other special conditions unique to the property and development involved as opposed to the mere inconvenience or financial disadvantage. The conditions are not the result of the applicant’s own actions. Granting of the waiver would not substantially conflict with the Comprehensive Plan. Because of these conditions, the application of this Code to the particular piece of property would effectively prohibit or unreasonably restrict the utilization of the property. The authorization of a waiver will not be of substantial detriment to adjacent property or the public good, and the character of the zone will not be harmed by the granting of the waiver. 6) Growth area overlay district (GA) Statement of purpose: The purpose of the growth area overlay district is to develop a clear growth zone for the city in order to be consistent with state requirements in 30-A MRS §4364 and 4364-A.
