18.10.010 Purpose and density of single-family zoning districts.
A. Purpose. The purpose of the single-family zoning districts in the city of Monroe is to promote the existing small town character by providing that new development will be compatible with the density and setbacks of the present housing stock. The purpose is also to provide for a broad range of housing types and densities. Areas designated urban residential are envisioned to be served by the city water and city sanitary sewer systems when developed to their zoned densities. Single-family lots shall be limited to one residence except as otherwise prescribed.
B. Standard Density Calculation. To calculate the number of possible dwelling units/lots for single-family zoning districts, remove twenty percent from the gross site area, in square feet, for roads, gutters, curbs, sidewalks, and retention areas and then divide the net site area in square feet by the minimum lot size to determine the base density. In the R-4 zone, remove twenty percent from the gross site area in acres for roads, gutters, curbs, sidewalks, and retention areas and then multiply the net site area, in acres, by four.
1. When calculating the maximum residential density, any resulting fraction 0.50 or over shall be rounded up to the next whole number and any fraction 0.49 or under shall be rounded down to the preceding whole number. For example, in the UR 6,000 zone, a one-acre site could yield six units (43,560 square feet x 0.80 = 34,848 square feet / 6,000 square feet = 5.8 units or six total units).
2. Nothing contained within this chapter guarantees the maximum defined density. The identified maximum residential density may not always be achievable due to unique site considerations including but not limited to critical areas, topography, right-of-way dedication, stormwater requirements, etc. (Ord. 026/2011 § 2 (Exh. 1); Ord. 1177, 1999)
18.10.020 Purpose of the multifamily zoning district.
A. Purpose. The purpose of the multifamily zoning district is threefold: to promote the small town character of Monroe by providing that new multifamily housing be developed on small lots mixed with other housing stock, that development be compatible with the present housing stock, and that multifamily development provide for a broad range of housing types and densities. When single-family dwelling units are constructed on multifamily lots, they shall be limited to one detached single-family residence per lot except as otherwise prescribed.
B. Standard Density Calculation. To calculate the number of possible dwelling units/lots, for multifamily and zoning districts, divide the gross site area by the minimum unit/lot size, in square feet, to determine the base density. In cases when multifamily parcels are subdivided into individual parcels, pursuant to MMC Title 17, the standards of MMC 18.10.010(B) apply. In areas that do not have a minimum lot size, multiply the net site area, in acres, by the maximum allowed number of units/lots per acre.
1. When calculating the maximum residential density, any resulting fraction 0.50 or over shall be rounded up to the next whole number and any fraction 0.49 or under shall be rounded down to the preceding whole number. For example, in the MR 6,000 zone, a one-acre site could yield eleven units (43,560 square feet / 4,000 square feet = 10.89 units or eleven total units).
2. Nothing contained within this chapter guarantees the maximum defined density. The identified maximum residential density may not always be achievable due to unique site considerations including but not limited to critical areas, topography, right-of-way dedication, stormwater requirements, etc. (Ord. 026/2011 § 2 (Exh. 1); Ord. 033/2008 § 6; Ord. 1177, 1999)
18.10.025 Purpose of the professional office zoning district.
A. Purpose. The purpose of the professional office (PO) zoning district is to provide an area for personal and professional service businesses that commonly locate in office buildings, such as banks, medical and dental clinics, accounting, law, real estate, insurance, travel agencies and similar businesses, as well as allowing residential use at varying densities, while providing a transitional zone between commercial and residential zoning districts. When single-family dwelling units are constructed on professional office lots, they shall be limited to one detached single-family residence per lot except as otherwise prescribed.
B. Standard Density Calculation. The density calculation for single-family units/lots will follow the requirements found in MMC 18.10.010(B). The density calculation for multifamily units/lots will follow the requirements found in MMC 18.10.020(B). (Ord. 026/2011 § 2 (Exh. 1); Ord. 033/2008 § 6)
18.10.030 Purpose of the commercial zoning districts.
The purposes of the commercial districts are to provide opportunities for the enhancement of existing commercial uses and for the location of new commercial development.
A. General commercial uses (GC) should be located on traffic corridors that have adequate capacities for traffic flow. Such location assures that uses do not generate traffic through residential areas. Uses located in this (GC) class should be designed into planned centers with safe and convenient access to minimize curb cuts and facilitate better parking and traffic flows.
B. Service commercial uses (SC) should be located at intersections of major and minor arterials or their intersections with collector roads. Service commercial areas should be designed so as not to disrupt traffic movement on the arterial and collector roadways. Access and egress should be kept at a minimum and should be so located that they do not conflict with traffic movement and queuing at intersections.
C. Downtown commercial uses (DC) should follow the vision outlined in the downtown master plan. (Ord. 026/2011 § 2 (Exh. 1); Ord. 006/2009 § 4; Ord. 1177, 1999)
18.10.035 Purpose of the mixed use zoning districts.
The purposes of the mixed use zoning districts are to integrate a mix of office, retail, light industrial, institutional, public facilities, and attached residential units throughout the district, within the same property, or inside a single building.
A. Mixed use commercial (MUC) should be located on corridors with available public services and adequate traffic capacities. The mixed use commercial district allows high-intensity development and requires that new developments provide safe and convenient access, minimize curb cuts, and facilitate better parking and traffic flow. This district permits residential, commercial, office, and light industrial land uses.
1. Residential Density. New residential development is limited to attached structures with a density between twelve and twenty dwelling units per acre. The density calculation for multifamily units will follow the requirements found in MMC 18.10.020(B).
2. Commercial Uses. Commercial uses should serve primarily the employment, housing, shopping, service, and recreational needs of those residing within the district and surrounding area. Individual commercial uses should be limited to thirty thousand square feet or less. The city may allow buildings up to sixty thousand square feet with a conditional use permit, per Chapter 18.96 MMC.
3. Design Standards. All development within the mixed use commercial zone shall comply with the Infill, Multifamily, and Mixed Use Design Standards, subject to the requirements of MMC 18.10.132.
B. Mixed use neighborhood center (MUNC) should be located on corridors with available public services and adequate capacities. Access points should prevent conflict with traffic movement and back-ups at intersections. This district permits residential, commercial, and office land uses.
1. Residential Density. New residential development is limited to attached structures with a density between eight and eleven dwelling units per acre. The density calculation for multifamily units will follow the requirements found in MMC 18.10.020(B).
2. Commercial Uses. Small-scale office, retail, and service businesses should meet primarily the convenience shopping and services needs of the immediate mixed use area. Individual commercial uses should be limited to ten thousand square feet or less. The city may allow buildings up to thirty thousand square feet with a conditional use permit per Chapter 18.96 MMC.
3. Design Standards. All development within the mixed use neighborhood center zone shall comply with the Infill, Multifamily, and Mixed Use Design Standards, subject to the requirements of MMC 18.10.132. (Ord. 026/2011 § 2 (Exh. 1); Ord. 024/2011 § 2 (Exh. 1))
18.10.040 Purpose of the industrial zoning districts.
The purpose of the industrial zones is to provide opportunities for enhancement of existing industrial and compatible commercial use and intensities in areas of the city which are suitable for such development. Suitability is based on characteristics such as existing land use, natural features, transportation, and utility service and associated environmental impacts.
Industrial areas should take advantage of rail and highway access points. Development should be separated or well buffered from nearby residential areas. The location of industrial zones should be dependent on and compatible with the size and scale of the surrounding adjacent uses. In addition, design standards are incorporated into the code to ensure compatibility with adjacent uses. (Ord. 026/2011 § 2 (Exh. 1); Ord. 1177, 1999)
18.10.043 Purpose of the limited open space airport zoning district.
The purpose of the limited open space airport zoning district is to protect the viability of First Air Field, a general aviation facility, encourage compatible land uses and densities, and reduce hazards that may endanger the lives and property of the public and aviation users in proximity to First Air Field. (Ord. 026/2011 § 2 (Exh. 1); Ord. 033/2008 § 6)
18.10.045 Purpose of the limited open space zoning district.
The purpose of the limited open space zoning district is to provide for low-density residential uses on lands that lack the full range of public services and facilities necessary to support urban development and that are severely impacted by critical areas. This zone also provides a buffer between urban areas and transitional land uses on the urban growth boundaries of the city, and/or may also provide for enhanced recreational facilities and linkages to existing trails or open space systems. (Ord. 026/2011 § 2 (Exh. 1); Ord. 033/2008 § 6)
18.10.047 Purpose of the public open space zoning district.
The purpose of the public open space zoning district is to provide areas to include public neighborhood, community and regional parks, recreational facilities, and undisturbed natural open space; public school facilities; public city facilities; and other special regional use facilities operated by the county, state, or federal government, within the city’s urban growth area. (Ord. 026/2011 § 2 (Exh. 1); Ord. 033/2008 § 6)
18.10.050 Zoning land use matrix.
The zoning administrator, under MMC 18.08.020, Interpretations, is charged with the responsibility of determining in which zone similar or like uses, not shown in the matrix, would be located and whether or not such uses are permitted outright, require a conditional use permit or special use permit, are an accessory use, or are prohibited.
A zoning matrix is used to summarize all land uses and districts to show at a glance both the uses permitted in a specific zoning district as well as the zones in which specific uses are permitted.

Notations to Zoning Matrix
1. Existing single-family dwellings in MUC are considered allowed, legally conforming uses. Existing single-family dwellings that are destroyed may be rebuilt within the building footprint as it existed immediately prior to the destruction. No other new single-family residences are permitted.
2. Existing single-family dwellings in MUC that are converted to a nonresidential use for no longer than twelve months may be converted back to residential use.
3. Existing single-family dwellings in MUNC are considered allowed, legally conforming uses. Existing detached single-family dwellings that are destroyed may be rebuilt in accordance with current code setback requirements. No other new detached single-family residences are permitted.
4. Existing single-family dwellings in MUNC that are converted to a nonresidential use may be converted back to residential use.
P1 Must be located within the city’s defined adult entertainment boundary.
P2 Requires one and one-half the minimum lot area of a single-family dwelling.
P3 Based upon bedrooms as opposed to dwelling units in any combination of one-, two- and/or three-bedroom units, not to exceed the maximum density allowed in the underlying zoning district. The standard formula would be to use the maximum allowed density per acre (forty-three thousand five hundred sixty square feet divided by minimum zone lot size) multiplied by three (standard bedroom equivalent unit) to achieve bedroom density. For example, in the MR 6,000 zone, a one-acre site could achieve thirty-three bedrooms per acre (43,560/4,000 = 10.89 or 11 dwelling units per acre x 3 = 33).
P4 All outdoor storage shall be enclosed by a six-foot-tall site-obscuring fence or wall, and shall include a Type III landscaping buffer along the exterior perimeter of the property or site (see MMC 18.78.030).
P5 Must meet criteria outlined in Chapter 18.40 MMC, Accessory Dwelling Units.
P6 The minimum lot size for duplex and multifamily structures shall be four thousand square feet per unit.
P7 Subject to Chapter 18.60 MMC, Airport Compatibility.
P8 Individual commercial uses should be limited to thirty thousand square feet or less. The city may allow buildings up to sixty thousand square feet with a conditional use permit per Chapter 18.96 MMC.
P9 Individual commercial uses should be limited to ten thousand square feet or less. The city may allow buildings up to thirty thousand square feet with a conditional use permit per Chapter 18.96 MMC.
P10 Drive-up facilities not permitted.
P11 If any outdoor caging of animals is proposed, a conditional use permit is required per Chapter 18.96 MMC.
C1 Limitation on number of children permitted per establishment.
C2 Group homes that qualify as essential public facilities shall follow the regulations in Chapter 18.15 MMC, Essential Public Facilities.
C3 Based upon bedrooms as opposed to dwelling units; see P3.
C4 If a parks and recreation facility is the primary use a conditional use permit will be required; if the facility is secondary to a larger project, the use is considered accessory.

18.10.140 Bulk requirements.
A. The bulk requirement tables establish the maximum lot coverage, height, and setback requirements for lots within the city by zoning district. The bulk regulation tables identify the standards for broad use categories including residential, mixed use, commercial/industrial, and open space and public use. Within each table, specific categories cluster individual zones together by function. For example, the residential use bulk requirements table divides the main category into subcategories of single-family and multifamily development; these are further refined to include subgroups such as mid-density multifamily/small lot single-family, urban residential, suburban residential, and rural residential. A final categorical refinement represents standard requirements and planned residential requirements for zoning districts and functional classifications.
B. All setbacks are measured from the outside lot line unless otherwise noted.

Notes:
1. MMC 18.12.200 defines residential lot requirements for the DC zone and MMC 18.10.140(B) defines residential lot requirements for mixed use zones.
2. The city will provide development incentives, by zoning district, as defined under the PRD columns for single-family and multifamily infill projects, south of US 2 and less than three acres in size, when the proponent designs projects that meet the Infill, Multifamily, and Mixed Use Design Standards, unless otherwise restricted. The density bonus and development modifications will not require an additional open space dedication as required in MMC 18.84.080 for planned residential developments.
3. The mid-density multifamily category includes the MR 6,000 and PO zones; however, the PRD standards only apply to MR 6,000 zone per Chapter 18.84 MMC unless otherwise restricted in this title.
4. Lot size is per dwelling unit unless otherwise specified.
5. Lot sizes for residential zoning districts may be reduced up to thirty percent to accommodate limited density transfers attributable to critical areas as authorized by MMC 20.05.070(I).
6. Duplexes are allowed at one and one-half times the underlying minimum lot size.
7. Refer to the open space and public use matrix for nonresidential standards (Table D).
8. To maintain proportionate lots, the minimum lot width-to-depth ratio for single-family lots will be approximately 1:2; that is, the lot depth should be approximately two times greater than the lot width. When townhomes or other attached housing units are built on separate lots, the lot width-to-depth ratio will be approximately 1:4 and the lot width can be reduced to twenty-five feet. There will be no minimum lot width or width-to-depth ratio for low-rise multifamily apartments/condominiums to maintain flexibility for lot configuration.
9. All lots shall have access to a public street and meet the minimum lot width requirement along the frontage. Lots fronting a cul-de-sac shall meet the minimum lot width at the building setback line.
10. Lots with access to a public street via private access easement or panhandle shall have a minimum frontage of not less than twenty feet in width at the public street and shall meet the minimum lot width at the setback line measured from the end of the panhandle or easement where it joins the wide portion of the lot. An access easement or panhandle shall be a minimum of twenty feet wide along its entire length; the remainder of the lot shall provide adequate area to comply with the bulk development requirements.
11. The standard front setback for zones that allow single-family uses is ten feet to the living area and twenty feet to the garage, unless otherwise specified. Front setbacks in zones that allow single-family uses along arterials will be twenty feet for both living area and garage.
12. When townhomes or other attached housing units are built on separate lots, a zero setback between units is permitted in allowed zones. The outside setback for attached housing units abutting a ROW, separate detached unit(s), or different zone will be ten feet.
13. The rear setback can be reduced to ten feet if parking is underground or in a structure underneath the unit for multifamily developments or parking is accessed off an alley/private drive to the rear and provides a maximum backup area of twenty feet including the alley or private lane.
14. The landscape buffer is along the perimeter of the lot.
15. The PRD landscape buffer is required along the outside of the development where it abuts a standard subdivision or different zoning district. This landscaped buffer may coincide with required open space.

It is expected that sound pressure level of noise radiated from any enterprise located in a zone will never exceed the above described values in any residential district between the hours of eight p.m. and seven a.m. and not more than ten percent of the time between seven a.m. and eight p.m., except construction between six a.m. and ten p.m.
F. Smoke. It is expected that smoke will not be emitted from any source in a light industrial zone in greater density or shade of gray than that described as No. 1 on the Ringlemann chart, except that visible gray smoke, of a shade not darker than that described as No. 2 on the Ringlemann chart, may be emitted for not more than four minutes in any thirty minutes. These provisions applicable to visible gray smoke also apply to visible smoke of a different color with an equivalent apparent opacity.
G. Dust, Dirt. It is expected that dust, dirt, fly ash or other airborne solids will not be emitted from any source in any zone in greater density than that described as No. 1 on the Ringlemann chart.
H. Vibration. It is expected that vibrations from any machine, operation or process will not exceed three thousandths of one inch displacement applied to the frequency range of zero to five thousand cycles per second, as measured at any point off the lot on which the machine, operation, or process is located.
I. Glare and Heat. It is expected that customary operation or process which causes offensive glare or heat will be conducted in a completely enclosed building, and that any such operation or process of any unusual or sporadic nature will be so conducted as to be invisible beyond the lot on which it is located.
J. Toxic Gases. It is expected that toxic gases or matter will not be emitted in quantities damaging to health, animals, vegetation, or which can cause any excessive soiling beyond the lot on which they are generated. (Ord. 1177, 1999)
