City of Augusta, ME Article III Zoning District Requirements

See the Table of Land Uses in the Base Zoning Districts, included as an attachment to this chapter.

§ 300-314 Urban Growth Area.

[Amended 4-20-2017 by Ord. No. 17-069; 8-1-2024 by Ord. No. 24-104]

A. The Urban Growth Area, as defined on the land use map of the 2023 Comprehensive Plan, includes the City's built-up portions. Building trends in this area indicate that it is primarily infilled and that redevelopment is beginning to occur. The Urban Growth Area is the area of the City where Augusta wishes to contain higher density and compact development. Water, sewer and storm drainage utilities are generally available or are planned to serve this area. Special attention is given to the area to protect residential areas from adverse impacts that may result from other land use activities, to retain its visual gateways into the City, to unify the capital complexes on both sides of the river with the downtown and Western Avenue, and to improve the City's image.

B. Major developments, as defined, shall be required to comply with the site plan review process outlined in Part 4.

§ 300-314.1 Residential Districts.

[Amended 12-6-1993 by Ord. No. 311; 12-18-1995 by Ord. No. 302; 6-3-1996 by Ord. No. 463; 8-19-1996 by Ord. No. 542; 10-21-1996 by Ord. No. 606; 7-17-2000 by Ord. No. 412; 2-12-2001 by Ord. No. 21; 4-2-2001 by Ord. No. 50; 10-25-2004 by Ord. No. 152; 2-20-2007 by Ord. No. 028; 4-20-2017 by Ord. No. 17-069; 8-1-2024 by Ord. No. 24-104]

The Residential District regulations are based on conventional zoning standards, listing permitted and conditional uses as well as minimum dimensional requirements.

A. Low Density Residential District (RA).

(1) Purpose. The RA District is established as a zoning district in which the principal use of land is for low-density residences which will encourage the development of attractive neighborhood living.

(2) Dimensional requirements. The following shall be considered minimums; where the minimum lot size law, special shoreland standards, or State of Maine Wastewater Disposal Rules impose greater requirements, those additional requirements shall be met:

(a) Lot area: 10,000 square feet (public sewer); 20,000 square feet (private sewer).

(b) Lot area per dwelling unit: 5,000 square feet.

(c) Lot frontage: 100 feet.

(d) Lot depth: 100 feet.

(e) Front setback: See § 300-515.

(f) Side and rear setback:

[1] Principal structures: 10 feet.

[2] Accessory structures: five feet.

(g) Minimum frontage for conversion to two or more dwelling units: 50 feet.

B. Medium Density Residential Districts (RB1 and RB2).

(1) Purpose. The RB1 and RB2 Districts are zones in which the principal use of land is for medium-density residences. Both are characterized by a mix of single-family and multifamily homes.

(2) Dimensional requirements. The following shall be considered minimums; where the minimum lot size law, special shoreland standards, or State of Maine Wastewater Disposal Rules impose greater requirements, those additional requirements shall be met:

(a) Lot area: 7,500 square feet (public sewer); 20,000 square feet (private sewer).

(b) Lot area per dwelling unit: 2,500 square feet.

(c) Lot frontage: 75 feet.

(d) Lot depth: 100 feet.

(e) Front setback: See § 300-515.

(f) Side and rear setback:

[1] Principal structure: 10 feet.

[2] Accessory structures: five feet.

(g) Minimum frontage for conversion to two or more dwelling units: 50 feet.

C. High Density Residential District (RC).

(1) Purposes. The RC District is a zone in which the principal use of land is for high-density residences. It contains large structures, many of which were designed for or have been converted to multifamily dwellings. In addition, this district is somewhat removed from major or local shopping areas and offers neighborhood services within the district.

(2) Dimensional requirements. The following shall be considered minimums; where the minimum lot size law, special shoreland standards, or State of Maine Wastewater Disposal Rules impose greater requirements, those additional requirements shall be met:

(a) Lot area: 7,500 square feet (public sewer); 20,000 square feet (private sewer).

(b) Lot area per dwelling unit: 1,650 square feet.

(c) Lot frontage: 75 feet.

(d) Lot depth: 100 feet.

(e) Front setback: See § 300-515.

(f) Side and rear setbacks: five feet (all structures).

(g) Minimum frontage for conversion to two or more dwelling units: 50 feet.

D. Resource Development District (RD).

(1) Purpose. The RD District encompasses the area on both sides of Mount Vernon Avenue. The area's highly congested mixed-use building pattern, its floodplain and steep slopes, its recreational opportunities and its function as a major gateway make this corridor as environmentally sensitive as it is economically attractive. It connects the Heart of Augusta with the City's growth area. The infrastructure capacity is strained. In recognition of these factors, and based on the policies outlined in the 2023 Comprehensive Plan, the RD District encourages low-intensity mixed-use development supporting residential/recreational activities and the commuting public.

(2) Dimensional requirements and performance standards.

(a) Dimensional requirements. Unless otherwise stated, the following shall be considered minimums. Where minimum lot size law, general or specific standards, or Maine Wastewater Disposal Rules impose greater requirements, those additional requirements shall be met. Notwithstanding § 300-309C, the minimum frontage requirements in the RD Zone shall be met.

[1] Minimum lot frontage: 100 feet.

[a] Maximum impervious area: 25%.

[b] Maximum building height: 35 feet.

[c] Minimum front yard setback/buffer (all structures): 20 feet.

[d] Maximum front yard setback/buffer (principal structures): 25 feet.

[e] Minimum side and rear setbacks (all structures): 10 feet.

[f] Minimum buffer adjacent to Bond Brook: greater of 25 feet or width of floodway.

[2] Minimum lot frontage: 125 feet.

[a] Maximum impervious area: 30%.

[b] Maximum building height: 35 feet.

[c] Minimum front yard setback/buffer (all structures): Buffer A applicable.

[a] Maximum impervious area: 35%.

[b] Maximum building height: 35 feet.

[c] Minimum front yard setback/buffer (all structures): Buffer A applicable.

[d] Maximum front yard setback/buffer (principal structures): Buffer A applicable.

[e] Minimum side and rear setbacks (all structures): 10 feet.

[f] Minimum buffer adjacent to Bond Brook: greater of 25 feet or width of floodway.

[4] Notes:

[a] The intent of the maximum front setback is to minimize structural intrusion into the floodplain; to encourage parking at the rear or to the sides of buildings; and to provide for green space between the road right-of-way and structures.

[b] Ord. No. 14-038, adopted 3-6-2014, eliminated the maximum setback of 25 feet from the north side of Mount Vernon Avenue.

(b) Performance standards.

[1] Buffers; parking lot perimeter; waiver provision. Perimeter parking lot buffers may be eliminated when common (shared) driveways/circulation patterns are provided between two separate lots.

[i] Freestanding: one; and

[ii] Sandwich board: one; and

[iii] Wall: one per wall facing street or parking lot.

[3] Access management (existing standard): one driveway per development per street frontage.

[4] Minimum separation between two-way driveways serving two separate uses: 100 feet (based on 25 mph).

[5] Minimum separation between one-way driveways on one lot or serving two separate uses: 50 feet.

[6] When two adjacent lots are combined for reuse or redevelopment resulting in the elimination of at least one driveway, the minimum separation between two separately owned/operated two-way driveways may be reduced to 50 feet.

§ 300-314.7 Riggs Brook Village District (RBV).

[Amended 12-3-2001 by Ord. No. 141-C; 11-20-2014 by Ord. No. 14-202]

A. Purpose.

(1) The Riggs Brook Village District (RBV), establishes commercial and residential land uses, land development requirements, infrastructure requirements, development design standards and open space amenities appropriate to fostering development of a new economic sector in Augusta. Riggs Brook Village will be a geographically and visually unique area wherein people can live, work, shop, converse, and recreate within walking, bicycling and quick commuting distance of one other. Attracting development of a new economic sector is critical to the improvement of the general welfare of current and future residents and businesses of Augusta, and the incorporation of higher design standards and amenities in the RBV District will be required to make Augusta competitive with other Maine cities as a location for knowledge-based businesses, workers and residents.

(2) It has been proven that allowance of a linear pattern of land use development results in a very inefficient use of land, resulting in vacant backlands, excessive infrastructure costs, and added commuting costs, known collectively as "development sprawl." The prevention of development sprawl is identified as the first of 10 goals of the Maine Growth Management Program (see 30-A M.R.S.A. § 4312, Subsection 3). The pattern of land development that will be strongly encouraged in Riggs Brook Village (the Village) in support of this goal shall be that of development parks that will create multiple lots or land uses out of a larger tract/parcel of land.

(3) Internal streets, stormwater, sewer, and water infrastructure will be required to achieve an appropriate density of Village development. The creation of independent, small lots in a linear fashion along Route 3 and Church Hill Road shall be strongly discouraged, and the creation of development parks that efficiently utilize backlands will be strongly encouraged so that the Village can economically support sewer, water and road infrastructure without subsidization from the remainder of the community.

(4) The design and scale of development projects in Riggs Brook Village shall be that of small and medium-sized structures that, along with defined setbacks, buffering, landscaping and sidewalks, encourage pedestrian and bicycle travel and human interaction. Residential land uses are encouraged throughout the Village in several configurations: townhouse/row house; two-family; and single-family. The identification of the Village as a unique and unified area shall be encouraged via the use of signage, lighting, and other streetscape improvements. Village greens should be created along Church Hill Road to provide a common Village focal point for each side of Route 3.

B. Dimensional requirements.

(1) Minimum lot size: 20,000 square feet.

(2) Minimum frontage on new internal roads: 100 feet.

(3) Minimum frontage on Rt. 3, Church Hill Road and South Belfast Avenue: 300 feet.

(4) Minimum depth: 200 feet.

(5) Area per dwelling unit: 20,000 square feet.***

(6) Minimum front setback: 10 feet/80 feet.**

(7) Maximum height: 60 feet.

(8) Notes:

(a) Minimum side/rear setbacks are flexible; see §§ 300-502 and 300-515.

(b) **Minimum front setback: 80 feet from street ROW line of arterial and collector streets; 10 feet from the street ROW line of all other streets.

(c) ***May be reduced to 2,500 square feet per dwelling unit if served by public sewer.

(d) See the arterial/collector street list in § 300-515C.

C. Design criteria. The following minimum design criteria shall be met within the Riggs Brook Village (RBV) District:

(1) Utilities. All utility services for new building/structure construction shall be placed underground.

(2) Outdoor lighting standards. The purpose of this subsection is to provide outdoor lighting standards to help ensure compatibility with neighboring uses, preserve our dark skies, and provide a more pleasant and comfortable nighttime environment while preserving the ability to install effective security lighting.

(a) Use of motion-sensing devices is encouraged; and

(b) Lighting shall not blink, flash or be of unusually high intensity or brightness; and

(c) All lighting fixtures shall be appropriate in scale, intensity and height to the use they are serving; and

(d) Lighting shall also conform to § 300-511A, C, D, E and F of this chapter.

(3) Location of parking, servicing, and loading areas for nonresidential uses. All off-street parking lots/areas/stalls, vehicle servicing areas (including gasoline/diesel pumps), and delivery and garage bay doors shall be located at the side or rear of buildings, the only exception being for handicapped parking spaces, which may be located at the front of the building. Buffer yard standards for Urban, Industrial, and Planned Development Districts identified in § 300-502 of this chapter are applicable to all parking lots with six or more spaces.

(4) Screening of machinery, equipment, storage areas, and other appurtenances for nonresidential uses. Open storage areas; exposed machinery, electrical/electronic equipment, heating and/or air-conditioning equipment, fuel tanks, etc. (whether located above the ground on structures or on the ground); areas used for storage and collection of rubbish; and areas determined to be similar to those listed must be visually screened from roads and surrounding land uses. Suitable types of screening for aboveground equipment, storage areas and appurtenances include landscaping (e.g., shrubs, plants, trees, fencing) and/or architectural elements (e.g., false walls, false roofing, masonry, blocks, etc.). Suitable types of screening on the ground include opaque wood fences and dense evergreen hedges of five feet or more in height. Where evergreen hedges are proposed, a temporary fence shall be built to provide screening until the evergreens are of sufficient height to hide the unit(s) being screened.

(5) Building design standards for new structures.

(a) Exterior building design. Buildings with exterior walls greater than 50 feet in horizontal length shall be constructed using a combination of architectural features and a variety of building materials and landscaping near the walls. Walls which can be viewed from public streets shall be designed using architectural features and landscaping (abutting the building) for at least 50% of the wall length. Other walls shall incorporate architectural features and landscaping for at least 30% of the wall length.

[1] Architectural features include but are not limited to the following: recesses, projections, wall insets, arcades, window display areas, awnings, balconies, window projections, landscape structures or other features that complement the design intent of the structure and are acceptable to the review authority. A portion of the on-site landscaping shall abut the walls so that the vegetation combined with the architectural features significantly reduce the visual impact of the building mass as viewed from the street.

(b) Building materials. The predominant building materials shall be materials that are characteristic of Central Maine such as brick, wood, native stone and tinted/textured concrete masonry units and/or glass products. Other materials such as smooth-faced concrete block, undecorated tilt-up concrete panels, or prefabricated steel panels should only be used as accents and not dominate the building exterior of the structure. Metal roofs may be allowed if compatible with the overall architectural design of the building. Materials shall be of low reflectance, subtle, neutral or earth-tone colors. The use of high-intensity colors such as neon, metallic or florescent colors for the facade and/or roof of the building are prohibited except as approved for building trim. The use of trademark colors will require approval by the Planning Board.

(c) Roof design. Roofs shall be designed to reduce the apparent exterior mass of a building, add visual interest and be appropriate to the architectural style of the building. Variations within one architectural style are highly encouraged. Visible rooflines and roofs that project over the exterior wall or a building enough to cast a shadow on the ground are highly encouraged. Architectural methods shall be used to conceal flat roof tops. Overhanging eaves, sloped roofs and multiple roof elements are highly encouraged. Mansard style roofs are discouraged.

(d) Customer entrance(s). Each building shall have at least one clearly defined, highly visible customer entrance using a combination of the following architectural features: canopies, porticos, arcades, arches, wing walls, and permanent above-grade integral planters.

(6) Additions to existing structures. The Planning Board may waive any of the design criteria outlined in this subsection via a conditional use permit process.

§ 300-315.3 Rural Ponds District (RPDS).

The RPDS District is patterned after the "Agricultural District" described in Part Two–Model Ordinance from author and land use planner Lane Kendig's book entitled "Performance Zoning," Copyright 1980, American Planning Association.

A. Purpose. The RPDS District is an area where highly erodible, shallow soils, steep slopes, wetlands, deer yards, shoreland areas and State of Maine wildlife management areas shall be protected. All new development and conversions shall be designed and located, and all land use activities shall be conducted in a manner that prevents additional phosphorous loading to Togus and Three Cornered Ponds especially and stringently protects the water quality of all other ponds. The vulnerability of the ponds to water quality degradation is taken into account. The protection of wildlife, fisheries, scenic, and forest values are given high priority. Residential and recreational uses are encouraged, and maximum densities shall be in keeping with the capacity of the ponds and groundwater supplies to accommodate new development without water quality degradation. Clustering and retention of open space will be favored over conventional development patterns.

B. New single lots or subdivisions involving four or fewer lots.

(1) In general.

(a) The conventional zoning process in Subsection C designates minimum lot sizes and buffer widths for single lots created after the effective date of this ordinance.

(b) Although all subdivisions are encouraged to utilize the performance zoning dimensional requirements listed in Subsection D, conventional residential subdivisions, involving the creation of four or fewer lots of construction of four or fewer units, may also utilize Subsection C to determine minimum lot sizes, if such developments do not exceed the following:

[1] Maximum length of new or upgraded road is 200 feet with cumulative driveway length not to exceed 450 feet for three lots or 600 feet for four lots; or

[2] If no new or upgraded road is proposed, the cumulative driveway length shall not exceed 950 feet for three lots or 1,100 feet for four lots; or

[3] Single-family or duplex residential development of one or two lots or two lots with less than 200 feet of new or upgraded road with cumulative driveway length not to exceed 150 feet for one lot or 300 feet for two lots; or

[4] Single-family or duplex residential development of one or two lots with no new or upgraded road with cumulative driveway length not to exceed 450 feet for one lot or 600 feet for two lots.

(2) Exceptions.

(a) Existing lots of record within Shoreland Districts. Single lots of record existing prior to the effective date of this ordinance and located in the Shoreland Zoning Overlay Districts shall comply with no lesser requirement than the minimum dimensional and performance standards outlined in the applicable shoreland district and § 300-528.

(b) Existing lots of record outside Shoreland Districts. Except as provided by § 300-312D, single lots of record existing prior to the effective date of this ordinance that are located in areas of the RPDS District not covered by the Shoreland Zoning Overlay Districts shall comply with no less than the minimum dimensional requirements, as outlined in the applicable Tables 315.3-A and 315.3-B in Subsection C(2), that most nearly conform to the existing lot size and soil conditions. No building permit shall be denied for an existing lot which is not able to meet the minimum buffer widths as established. If necessary, due to site conditions and lot configuration, the minimum buffer width may be reduced to 20 feet without obtaining a variance from the Board of Zoning Appeals.

(3) To determine minimum lot size:

(a) In creating a new lot or a subdivision of four or fewer lots/units as outlined above, the lot owner or applicant shall consult with City staff to determine in which watershed the property is located.

(b) Upon such determination, and upon obtaining a soils test for on-site waste disposal suitability, Subsection C(1) shall be consulted and the applicant or lot owner shall be directed to utilize either Table 315.3-A or 315.3-B in Subsection C(2) to determine the minimum lot size required in order to control phosphorous loading into the affected pond.

(c) The soils test shall be performed by a professional engineer or soil scientist registered or licensed in the State of Maine with the authority to conduct such a test. The soils test shall indicate what hydrologic soils group (see definitions) exists on the site in the area where placement of the septic system and structures is to occur, and shall be matched with the appropriate lot size noted in Table 315.3-A or 315.3-B in Subsection C(2).

(d) Lots occurring in more than one watershed shall comply with the regulations of the district (RPDS/RRES or RPDS/RR) or subwatershed (e.g., Lower Togus/Wellman Ponds) in which 51% or more of the lot area exists.

	Tables 315.3-A and 315.3-B in Subsection C(2) were derived from the chart included in Appendix B of this ordinance. The chart was created by the DEP Water Quality Division and includes: pond or lake name; its water quality category; the direct drainage area in acres; the level of protection desired by the City of Augusta; a measure of additional phosphorous that, exported from the watershed to the lake, would produce a one-part-per-billion increase in the lake's phosphorous concentration; and the "P" value, the maximum acceptable increase in the amount of phosphorous exported per acre of watershed on a yearly basis. The full description of the process for determining the "P" factor can be found in "Phosphorous Control in Lake Watersheds, A Technical Guide to Evaluating New Development" (Guide), Maine Department of Environmental Protection, September 1989.
	Table 315.3-A was created by grouping all ponds with a "P" value greater than 0.07 and reflects a variation of the Guide's Table 4-1 on page 26; Table 315.3-B was created by grouping all ponds with a "P" value below 0.07 and also reflect a variation in the Guide's Table 4-1. Even though the chart in Appendix B lists "P" values for each pond, the intent of these regulations is to simplify the application of the regulations while providing a determined amount of phosphorous loading protection for each pond based on the DEP's work.
	As water quality monitoring work by the DEP and others proceeds, Tables 315.3-A and 315.3-B will be reevaluated and adjustments made where necessary.

C. Conventional zoning process.

(1) Dimensional requirements. [See also Subsection C(2) below.]

(a) Minimum lot size for all uses.

	Watershed	For Minimum Lot Size, Refer to
	Anderson Pond	Table 315.3-A
	Dam Pond	Table 315.3-A
	Little Togus Pond	Table 315.3-A
	Lower Togus Pond	Table 315.3-A
	Spectacle Pond	Table 315.3-A
	Togus Pond	Table 315.3-A
	Tolman Pond	Table 315.3-A
	Unnamed Pond	Table 315.3-A
	Greeley Pond	Table 315.3-B
	Mud Pond	Table 315.3-B
	Three Cornered Pond	Table 315.3-B
	Wellman Pond	Table 315.3-B

(b) Minimum area per living unit shall be no less than the minimum lot size.

(c) Minimum road frontage: 150 feet; minimum depth: 100 feet.

(d) Side/Rear setbacks are flexible; see minimum buffer widths.

(e) Front setback: 35 feet from the street line of arterial and collector streets; 20 feet from the street line of all other streets.

(f) The total area of all structures, parking lots and other nonvegetated surfaces shall not exceed 20% of the total lot area.

(g) Additional water quality measures may be required in accordance with section

(2) Lot size based on hydrologic soil group.

(a) Use of Tables 315.3-A and 315.3-B requires determination of hydrologic soil group before determining the minimum lot size. Once the hydrologic soil group has been identified through a subsurface wastewater disposal soil test, a lot owner must agree to maintain the required buffer width at all perimeter property lines. No more than 20% of the parcel may be covered with structures, parking areas and other nonvegetated surfaces. Driveways shall be included in the calculation of total impervious surface; however, total square footage of gravel driveways may be discounted by 50%. A gravel driveway 15 feet wide and 100 feet long equals 1,500 square feet; however, only 750 square feet is required to be used in the calculation of total area covered by structures, parking areas and other nonvegetated surfaces. Paved driveways shall be calculated at 100% of their area.

(b) With respect to Tables 315.3-A and 315.3-B, subsurface wastewater disposal soil tests indicating soil profile and condition are translated into hydrologic soil groups through the use of Appendix B.2 found at the back of this ordinance. As an example, profile and condition 6B translates in a hydrologic soil group of "A." For a parcel in the Togus Pond watershed, Table 315.3-A specifies that soils have a hydrologic soil group A require a one-acre minimum lot size and a twenty-foot perimeter buffer.

	Table 315.3-A
	If Hydrologic Soil Group Is	Minimum Lot Size (acres)	Minimum Buffer Width Required Along Perimeter Property Line (feet)
	A	1.0	20
	B	2.0	30
	C	3.0	40
	D	4.0	50

	A	1.5	40
	B	2.5	50
	C	4.0	60
	D	5.0	70

D. Performance zoning process. Projects utilizing the performance zoning process outlined below shall perform a site capacity analysis (Article IV) to determine the dwelling units per acre or FAF, as applicable. Once this determination has been made, the applicant shall comply with all applicable performance standards outlined in Part 5 of this chapter and shall pay particular attention to § 300-514B(3), Phosphorus control standards, and Part Two of the Guide noted.

They may, however, be represented by an agent or attorney at any meeting of the Commission. If the property owner is not present, any person acting as the property owner's agent or attorney shall provide evidence of such authority.

M. Administrative procedures.

(1) Notice to owners. Before meeting to review an application for an historic preservation certificate, the Commission shall notify by United States mail, the applicant, abutting property owners, and the owners of property within 500 feet of the property that is the subject of the application. The notice shall be sent to the person who receives the property tax bills at the address shown in the municipal tax records. Failure of any person to receive notice shall not necessitate another public meeting or hearing nor invalidate any action by the Commission.

(2) Hearing. At the request of the applicant or any other person receiving notice under Subsection M(1) above or when the Commission deems it necessary, a public hearing on the application shall be conducted by the Commission.

(3) Procedure of the Commission. The Commission shall consider the application at a meeting. A minor change, as defined in Subsection E, shall ordinarily be approved and without conditions. The judgment of at least one professional consultant may be obtained in reviewing any major change involving issues of design. The Commission shall approve, approve with conditions, or deny the application pursuant to Subsection N(4) and (5). The review period may be extended by mutual agreement of the Commission and the applicant, either written or oral, on the record at a public meeting.

(4) Approval. If the Commission finds the application meets the standards of evaluation as detailed in Subsection N, it shall issue a decision to grant an historic preservation certificate. Within seven days of its decision, the Commission shall furnish the applicant a copy of the application, a written decision including written findings of fact supporting the decision and any written recommendations. The Commission shall also furnish copies of these documents to the Code Enforcement Officer for filing in the City Map and Lot files.

(5) Conditional approval and disapproval.

The Commission shall also furnish copies of these documents to the Code Enforcement Officer for filing in the City Map and Lot files.

N. Standards of evaluation.

(1) General.

(a) The Commission's areas of focus shall be matters affecting the maintenance of historic structures, the protection of archaeological resources, and the preservation of the historic character of viewscapes.

(b) The standards of evaluation described below and elsewhere in this section are intended for the evaluation of contributing properties. Changes to a noncontributing property are considered only insofar as they may affect the historic integrity of the viewscape or the district as a whole.

(2) Reconstruction, renovation and alteration.

(a) Except as specified in Subsection L, a structure designated as an historic landmark or site or a structure located in a designated historic district, or related structures or improvements, such as walls, fences, light fixtures, steps, or paving located in a designated historic district, shall not be altered, and no historic preservation certificate shall be issued for such actions unless these actions will preserve or enhance the historical and architectural character of the structure, and are visually compatible with the viewscape.

(b) Every reasonable effort shall be made to use a property for its originally intended purpose or to provide compatible use for a property that requires minimal alteration to the character-defining features of the structure or site and its environment. When NFPA Life Safety 101 Code modifications subject to the Historic District Ordinance are made to a structure, every effort shall be made to accommodate the standards of the Historic District Ordinance while meeting the NFPA Life Safety 101 Code requirements. The Commission shall review the cost of complying with NFPA Life Safety 101 Codes and determine that the changes made have the least impact possible on the historic characteristics of the structure, while still enabling the building to generate a reasonable return to the owner. In cases where the originally intended purpose of the structure has been modified over time, those changes shall be considered during the Commission review of the application.

(c) Rehabilitation work shall not destroy or displace the distinguishing features or character of a structure and setting. Distinctive stylistic features that characterize historic structures shall be preserved wherever possible.

(d) All structures and sites shall be recognized as products of their own time. Alterations that have no historical basis or create a false sense of historical development, such as adding conjectural features or elements from other properties, shall be discouraged.

(e) Changes that may have taken place in the course of time are evidence of the history and development of a structure or site and its environment. These changes may have acquired significance in their own right, and this significance shall be recognized and respected. Features not original to the structure and that have not acquired their own significance are deemed noncontributing and, therefore, can be replaced according to standards under Subsection O(2)(g) or (j).

(f) Distinctive stylistic features or examples of skilled craftsmanship that characterize a structure or site shall be treated with sensitivity.

(g) Deteriorated architectural features of structures, or settings, shall be repaired rather than replaced whenever possible. In the event replacement is necessary, the new material should match the material being replaced in composition, design, texture and other visual qualities. Repair or replacement of missing architectural features should be based on accurate duplication of features, substantiated by historic, physical or pictorial evidence, rather than on conjectural designs or the availability of different architectural elements from other structures.

(h) The surface cleaning of structures shall be undertaken with the gentlest means possible. Sandblasting and other methods that will damage the historic building materials shall not be undertaken.

(i) Every reasonable effort shall be made to protect and preserve archaeological resources affected by or adjacent to any project.

(j) Contemporary design for alterations and additions to existing properties is permitted when it does not destroy significant historical, architectural or cultural material, and the design is compatible with the size, scale, material and character of the property, neighborhood or environment. In particular, modern energy systems and their features (solar panels, heat pumps, etc.) shall be allowed to be incorporated into properties with an effort to make them fit into the character of the property and neighborhood as best as possible.

(k) Whenever possible, new additions or alterations to structures shall be done in such a manner that if such additions or alterations were to be removed in the future, the essential form and integrity of the structure would be unimpaired.

(3) Construction and/or placement of new buildings and other structures in historic districts.

(a) The construction and/or placement of a new building or other structure shall be in keeping with the surrounding area and compatible, as defined in Subsection E, with other structures in the historic viewscape to which it is related.

(b) The Commission shall review associated elements visible from the street, such as fences, walls, and signs to protect the district's viewscape.

(4) Visual compatibility factors for new construction and additions. Within historic districts, historic sites or landmarks, all new construction and all new additions shall be visually related.

(a) Height. The height of proposed buildings and other structures shall be visually compatible with adjacent structures.

(b) Proportion of building's facade. The relationship of the width of the building to the height of the front elevation shall be visually compatible with nearby buildings and open spaces.

(c) Proportion of opening within the facade. The relationship of the width of the windows to the height of the windows and doors in a building shall be visually compatible with the windows and doors of nearby buildings.

(5) Demolition or removal. An historic landmark, or any structure in an historic district or any attached structure, whether residential or commercial, shall not be demolished or removed and an historic preservation certificate to do so shall not be issued unless one of the following conditions is met:

(a) The structure has been identified by the Commission as noncontributing or incompatible with the historic district in which it is located; or

(b) The property owner can demonstrate that it cannot be renovated or reconstructed so as to earn an economic return on its value in its present location as determined by a qualified real estate appraiser.

O. Maintenance and repair. The property owner or the person in charge of an individual historic property, a structure within an historic district or of an historic landmark shall not allow that structure or landmark to fall into a state of deterioration by neglect. This condition consists of the deterioration of any exterior structural or architectural feature to such a degree that it would produce, in the judgment of the Commission, an irremediably detrimental effect on the life and character of that historic structure or landmark and that could lead to a claim that demolition is necessary for public safety. When the Commission acquires evidence of such deterioration, it shall notify the Code Enforcement Officer who will in turn notify the property owner of the potential violation of this section. This condition of deterioration includes but is not limited to:

(1) The deterioration of exterior walls or other vertical supports.

(2) The deterioration of roofs or other horizontal members, including the ineffective waterproofing of exterior walls, roofs and foundations, as well as broken windows and doors.

(3) The deterioration of exterior chimneys.

(4) The deterioration of exterior plaster or mortar.

(5) The deterioration of any feature to the extent that it would create or permit the creation of any hazardous or unsafe condition.
