- Zoning District and Uses

_____


4.01 - Zoning Districts

A.

Intent. To carry out the purposes of this code, the following districts are established, with the intent given for the character of specific areas, the development patterns and context, and the types or intensity of uses and buildings.

Table 4-1: Zoning Districts & Intent
District & Intent
Relationship to
Comprehensive
Plan
A/R—Agriculture/Residential. The A/R district is intended for little or no development. These districts allow agriculture and associated uses, and include rural density residential living with detached houses on very large lots. Due to the development patterns and inefficiency of providing city services, this area receives only limited infrastructure investment and is therefore used as a "pre-development" district to either preserve open and rural lands, or hold areas until more coordinated, compact, and efficient growth and development can occur. Limited application as a pre-development area.
RE and AE—Rural Estate and Agriculture Estate. The RE and AE districts are intended for very low density residential living with detached houses on larger lots. These districts permit limited farming, agriculture and similar, less intense rural uses that are compatible with low density living. Due to the dispersed development intensity, this area receives lower levels of infrastructure and public service, and should be very limited in application based on the Comprehensive Plan, unless used in association with planned conservation or agricultural preservation patterns. Limited application on the edges of areas.

Planned applications for conservation or agricultural preservation.
R-1—Single-Family Residential. The R-1 district provides residential living (detached houses) in low-density suburban neighborhood settings with access to supporting uses such as schools, churches, parks and other public facilities. General application in low-density residential areas or limited application to provide larger lots at the edges of walkable neighborhoods.
R-1A—Single- and Two-Family Residential. The R-1A district provides residential living (detached houses and duplexes) in low-density suburban neighborhood settings, with access to supporting uses such as schools, churches, parks and other public facilities. This district may also be used in limited applications to provide larger lots in, walkable neighborhoods, when integrated with other zoning districts that provide additional housing types and access to activity centers. General application in low-density residential areas or limited application to provide larger lots at the edges of walkable neighborhoods.
R-1B—City Neighborhood Residential. The R-1B district provides residential living in compact, walkable neighborhood settings (limited range of small-scale residential building types), and integrates supporting uses such as schools, churches, parks and other public facilities that reinforce residential neighborhoods. This district should be close and connected to zoning districts that provide a broader range of housing types and access to downtown and other activity centers. General application in moderate density residential and as the predominant component of walkable neighborhoods, typically near downtown or other walkable activity centers and destinations.
R-2—Mixed-Density Residential. The R-2 district provides residential living (wide range of small-scale residential building types) in a compact, walkable neighborhood settings allowing a mix of housing options at strategic locations which transition to complimentary and supporting non-residential uses. A well-designed public realm provides the focal point to integrate a variety of building types with a consistent neighborhood character. General application in moderate and high-density areas, as a complimentary component of walkable neighborhoods or the predominant residential component of downtown, mixed use areas, and transit-served nodes.
R-3—Multiple Family Residential. The R-3 district provides residential living in a moderate-density pattern in suburban neighborhoods located in areas that have transitions between lower-density neighborhoods or more intense non-residential uses and where a high level of accessibility, public amenity and support services are immediately available. General application in high-density areas
MH—Manufactured and Small-Format Housing District. The MH district provides residential living for manufactured, mobile, or small format homes in a planned community that shares common amenities located in areas that have transitions between lower-density neighborhoods or more intense, non-residential uses, and where a high level of accessibility, public amenity, and support services are immediately available. See Section 5.07 Manufactured and Small-Format Housing District. Limited application on a project specific basis, considering context and design.
DT—Downtown. The DT district provides a broad range of retail, entertainment and civic uses and supporting office, service, and residential uses in a compact and walkable format. This district preserves the historic "main street" scale and small town character of Brighton. It is the vibrant heart of the community with a high level of civic design, walkable urban patterns, and a concentration of diverse, small-scale uses. General application for Downtown Brighton.
MU—Mixed Use. The MU district provides a mix of retail, service, employment, entertainment and civic uses in a walkable setting. The district includes three variants based on scale and intensity of development:
• MU-NC Neighborhood Center - intended for small-scale, neighborhood serving activity centers tightly integrated with and serving the daily needs of adjacent neighborhoods (typically under 10 acres);
• MU-CC Community Center—providing daily, discretionary and entertainment in a format that is an active destination for broader community, and designed in a way that compliments higher-density neighborhoods (typically 10 to 30 acres); and
• MU-E/REC - providing for regional shopping, employment, or institutional uses, arranging them as the heart of a multi-modal regional destination (typically larger than 30 acres).

Each of these areas requires a high level of accessibility, public amenity and civic design to serve as the organizing element of a broad range of uses and building types.
MU-NC - General application for mixed use commercial, commercial, or any format where commercial uses support surrounding areas in a walkable context.

MU—CC General application mixed use commercial in the Urban Centers, or the edges of downtown, or commercial areas along major arterials

MU-RC—Limited application in association with the strategic location of large scale retail, instructional or employment uses.
C-O—Commercial Office. The C-O district provides administrative, professional and limited personal services in a low or moderate intensity format that can be compatible with adjoining residential districts or low-intensity uses. It is generally located near residential neighborhoods an along minor arterial streets. General allocation in commercial areas or as support uses on the edges of mixed use centers.
C-1—Local Retail. The C-1 district provides small-scale retail, service, civic and employment uses to support suburban or walkable neighborhoods. It is generally located near residential neighborhoods an along minor arterial streets. General allocation in commercial areas, or as support uses on the edges of mixed use centers.
C-2—Restricted Retail and Services. The C-2 district provides a wider variety of small and moderate scale retail, service, civic and employment uses. It is centrally located and along arterial streets or intersections, and where transitions and buffers between lower-density residential and low-intensity uses are possible. Limited application in commercial areas along corridors, and where mixed-use designations may not accommodate uses.
C-3—General Retails & Services. The C-3 district provides wide range retail, service and employment uses at a scale, intensity or in a format that requires a high level of vehicle accessibility and visibility, typically along corridors or major intersections, and is not easily integrated with other land uses or development patterns. Planned versions of this district can yield campus or mixed-use district patterns that are oriented to internal open space systems or other focal points of development. Limited application in commercial areas along major thoroughfares and where mixed-use designations may not accommodate uses.
BP—Business Park. The BP district provides planned business, employment and light manufacturing uses, and supporting services arranged in a campus development pattern around common amenities, well-designed open space systems, and internal circulation systems. It is typically along corridors or major intersections and not easily integrated with other land use patterns. Limited application based on specific campus designs, and where mixed-use designations may not accommodate uses.
I-1—Light Industrial. The I-1 district provides primarily service, employment, manufacturing and distribution uses at a scale, intensity and format that won't have significant impact on adjacent uses, and which can mix with supporting and compatible service and retail uses. General application in industrial areas, and limited application on the edges of Mixed-use Community Centers or Mixed-use Regional Centers
I-2—Heavy Industrial. The I-2 district provides for the broadest scope of service, manufacturing and distribution uses that are generally not compatible with residential or commercial activity due to the scale, operation, intensity or impacts of activities, or due to the high level of transportation access and support infrastructure required of the business. Limited application in industrial areas or other locations on major regional freight routes.

4.03 - Accessory Uses

In addition to the general use and development standards applicable to all districts, permitted uses may include other accessory uses. This section provides basic performance standards for all accessory uses and some specific standards for particular accessory uses.

A.

Accessory Uses, Generally. All principal uses shall include accessory uses subject to the following general standards:

1.

The use and any structure is clearly incidental and subordinate to an allowed use and customarily associated with the allowed use.

2.

The use is on the same lot as the principal use or otherwise clearly associated with an active principal use.

3.

The use is compatible with the general character of the area and comparable in scale and intensity to uses of other property in the vicinity.

4.

No use or structure may be constructed, maintained or conducted in a way that produces noise, vibration, noxious odor or material, any visible light, glare or other visible impacts that are harmful, damaging or disturbing to the adjacent property.

5.

Any structures or site design elements to support the use can be screened or located to minimize impact on adjacent property or are not significantly different from what is typical for other allowed uses in the district.

6.

There are no unusual traffic patterns or increases in operational activity that impact the use and design of streets and public spaces differently that other allowed uses.

7.

All uses and structures are conducted in a way that is consistent with the intent and objectives of all other design and development standards applicable to the property.

B.

Accessory Dwelling.

1.

Residential. A dwelling unit that is secondary to another dwelling unit on the same lot, known as an Accessory Dwelling Unit or ADU, is allowed as an accessory use to a primary residential building (the "principal building") in zone districts where detached houses or duplexes are allowed. An ADU is not considered an accessory building as referenced in this code and is subject to the following standards:

a.

One ADU is allowed per lot, and an ADU is allowed only where the principal building is a detached house or duplex (see Accessory Dwelling - Agricultural, Commercial, or Industrial for caretaker or watchman homes).

b.

ADUs shall provide an entrance and living, sleeping, cooking, eating, and sanitation facilities independent from those of the principal building. ADUs shall not be mobile homes, motor homes, park models, other recreational vehicles, or other temporary shelters.

c.

New and existing planned developments and planned unit developments that allow the construction of one or more single-unit detached dwellings shall not restrict ADUs more than this code restricts ADUs outside of a planned development or planned unit development or in any way that is prohibited by C.R.S. 29-35-103 as amended.

d.

ADUs may be located (a) detached from the principal building, (b) within or attached to an accessory building such as above a detached garage, or (c) within or attached to the principal building. An ADU located entirely within the principal building, such as in an attic or basement, is known as an internal ADU.

e.

An ADU shall not be subdivided, converted to a condominium, or otherwise severed in any way from the principal building property or ownership.

f.

An ADU shall have an address assigned to it that differs from that of the principal building. Depending on the location of the ADU, the principal building address may change.

g.

The applicant is responsible for verifying that adequate utility services will be in place for both the ADU and the principal building. The property owner shall obtain the necessary approvals and be responsible for the installation of the utilities necessary to serve the ADU, including when increased service capacity is required.

h.

ADUs shall meet all development and design standards in Article 5, Accessory Dwelling Unit (ADU) Design Standards.

i.

Off-street parking specific to an ADU is not required unless all 3 of the following conditions apply, in which case one off-street parking space shall be provided on the lot [if]: (a) there is no existing off-street parking space on the lot, (b) the lot is located in a zone district that requires one or more parking spaces for the principal building, and (c) the lot is located on a block where on-street parking is prohibited. Driveways serving ADUs shall meet all standards in Articles 5 and 7.

2.

Agricultural, Commercial, or Industrial. Dwellings for a caretaker or watchman shall be accessory to a principal agricultural, commercial, or industrial use on the lot, are not Accessory Dwelling Units (ADUs), and are subject to the following additional standards:

a.

The principal use must be a lawful conforming use.

b.

The caretaker/watchman dwelling unit shall be for occupancy by the caretaker or watchman employed on the premises.

c.

Only one (1) caretaker/watchman dwelling unit shall be allowed in conjunction with a principal lawful use and shall be clearly ancillary to the primary business or use.

d.

The caretaker/watchman dwelling unit may be a detached building or within or attached to the principal non-residential building. If a detached building, the caretaker/watchman dwelling unit is in addition to the accessory buildings allowed in Section 6.02.

e.

In addition to the parking required otherwise on site, one off-street parking space shall be provided for the exclusive use of the caretaker/watchman.

f.

The applicant shall demonstrate proof of adequate utility services for both the principal use and caretaker/watchman dwelling unit.

g.

Proof of adequate access shall be provided.

h.

No caretaker/watchman dwelling unit shall be deeded, sold, leased, or rented without conforming to the subdivision and zoning regulations.

i.

Driveways shall meet all standards in Articles 6 and 7.

C.

Home Occupation. Home occupations shall meet all of the following standards:

1.

The occupation shall be limited to residents of the dwelling and no non-resident employees. If the resident applicant is not the homeowner, the homeowner shall provide a notarized authorization with the permit application.

2.

No more than 25% of the floor area of any one floor of the dwelling unit shall be utilized for a home occupation except as may be required for state-licensed family child care homes.

6.

No traffic shall be generated by the home occupation that is abnormal to a residential neighborhood. Any deliveries shall be from vehicles 16 feet or less or rated 8,000 pound gross vehicle weight or less, except for limited larger vehicles at a frequency typical of the principal residential use.

7.

All activity shall be conducted with an enclosed living area or the garage, except as required for state-licensed family child care homes.

8.

No equipment, machinery or operation shall be used in such activities that is perceptible off the premises because of noise, smoke, odor, dust, radiation, electrical interference or vibration.

9.

No home occupation shall produce on a regular or repeated basis quantities or types of refuse not customarily associated with a normal residential use in that zone district.

10.

Only up to 10 customer or patron visits per day shall be permitted and limited to between the hours of 7 a.m. and 7 p.m. There is no restriction on the number of customers or patrons visiting at any given time, so long as the total number of visits per day does not exceed 10 and all other specific and general accessory use criteria are met. All parking necessary for the use shall be confined to the garage, driveway or street directly in front of the dwelling.

11.

The operation of any wholesale or retail business is prohibited unless it is conducted entirely by mail or sales are transacted no more than once per week (i.e., Tupperware party). Incidental sales of products associated with a service shall be permitted (e.g., instructional books sold in conjunction with music lessons).

12.

Any person operating a home occupation shall obtain a home occupation permit from the Community Development Department, and submit any other local, state or federal government or agency licenses necessary for the proposed business. The Director shall either issue the permit or notify the applicant in writing as to why the permit does not meet these standards. The Director may condition the permit on any specific conditions necessary to ensure these standards are met and maintained.

13.

Permits shall be valid for up to 1 year, may be revoked at any time for non-compliance with these standards or conditions, and shall be void if the applicant ceases engaging in the home occupation or does not reside on the premises for more than 60 days.

14.

Specific home occupation conditions:

4.05 - Special Purpose & Overlay Districts

A.

South 4th Street Overlay District (S4).

1.

Intent. The South 4 th Street Overlay District is intended to allow a broader range of uses in a scale and format that is compatible with the residential character of the area. It allows small-scale and neighborhood-compatible commercial for reuse of residential structures and small-scale commercial buildings at key nodes. It is divided into a "gateway" portion (S4GW), primarily at the transition to downtown and at Bromley Lane, to promote development that creates greater activity and serves as signature entry to the neighborhood and a "corridor" portion (S4CR) that preserves the neighborhood scale and character for the edges of surrounding neighborhoods and length of the corridor.

2.

Applicability. The South 4 th Street Overlay District is an overlay district that applies in addition to the base zoning district for areas designated on the official zoning map. Specifically it applies to all property abutting 4 th Street between Bridge Street and Bromley Lane, and is further designated as "gateway" and "corridor" as indicated on the official zoning map

3.

Uses. The Sough 4 th Street District is specifically intended to promote the adaptive reuse of residential structures with limited, small-scale and neighborhood compatible structures, while preserving the residential character of the area and residential uses within the corridor. Table 4-2 provides uses allowed in the S4GW and S4CC district and overrides the uses permitted in the base zoning districts.

4.

Development Standards. The development standards applicable to the base zoning districts shall apply, except that the allowed building types and frontage types are specifically modified in Section 6.04.D. Specifically, the S4GW district shall allow C-1 building types, follow the non-residential design standards, and require Street-front or Terrace frontages, and the S4CR district allows R-1-B building types, follows residential design standards, and requires terrace or Neighborhood Yard frontage types.

5.

Performance Standards. In addition to all other building and site design standards, the following specific performance standards apply in the S4 district.

a.

Any use designated a conditional use in the S4 district shall be restricted to buildings up to 2,000 feet or up to 3,000 feet on corner lots.

b.

Any storage areas or trash bins shall be located behind the building and towards the back of the lot so they are not visible from 4 th Street and otherwise screened from adjacent property according to the standards in Article 8.

B.

Open Space District (O).

1.

Intent. The Open Space district is intended to preserve public and private open space. It ensures that a wide range of open and civic spaces are integrated into the development patterns of the City, appropriate to the context or inherent natural features of the area.

2.

Applicability. The Open Space district is a special purpose district for areas designated on the official zoning map and typically applies to public, common or private lands designed to be used as open or civic space.

3.

Uses. The Open Space district preserves open spaces and the uses designated in Table 4-2 shall control in the O district. Also note that all parks and open spaces are allowed in all districts, and it is not necessary to be in the O district to develop portions of the Open and Civic Space system.

4.

Development Standards. The Open Space district is intended for development of public, common, private open, or civic spaces. Development should occur according to the design types specified in Section 3.02. The O district may include buildings or structures, only to the extent they support the essential function of the open spaces. In these cases, all buildings shall follow the non-residential building and design standards.

C.

Mineral Extraction District (ME).

1.

Intent. The Mineral Extraction district is intended to allow limited use of property for the specific purpose of mineral extraction, subject to following all federal, state or local rules, guidelines or industry standards that protect the public health, safety and welfare, and subject to proper mitigation, operation, and reclamation of the lands for other uses once the mineral extraction is complete. The district promotes the reasonable and uniform limitations, safeguards and controls for the conservation and wise utilization of natural resources and for rehabilitation of excavated land.

2.

Applicability. The Mineral Extraction district can apply as an overlay district or as a special purpose district for areas designated on the official zoning map. In cases where it applies as an overlay district, the standards of the base zoning district control, and the ME district standards supplement those standards to the extent necessary to permit proper mineral extraction. In cases where it is applied as a special purpose district, the ME district standards apply, but should any change in the ME district occur, the property shall revert to the A/R zoning district standards, unless another district is specifically designated at that time. In all cases, the ME district should convert to the Open Space (O) district upon reclamation of the mineral extraction areas.

3.

Uses. The Mineral Extraction district includes land designated as containing commercially feasible mineral deposits in sufficient size parcels and in areas where extraction and rehabilitation can be undertaken while still protecting the health, safety and welfare of the inhabitants of the area and the City. In cases where the location of the District or use abuts other zoning or use, use of land, structures, excavation and rehabilitation may be restricted to be compatible and protect the adjoining areas. The uses designated in Table 4-2 are permitted in the ME district, or supplement any other uses permitted in the any underlying zoning district in cases where it is designated as an overlay district.

4.

Development Standards. No permanent structures may be constructed on mineral conservation districts, except fences, without demonstrating by competent proof that either minerals are not of commercial quantity and quality, or that such construction will not prohibit eventual extraction. Where structures are allowed, the minimum requirements of the R-1 or C-1 District shall be followed where applicable, except by special or conditional use permit.

5.

Excavation and Rehabilitation Plan. The extraction of commercial mineral deposits with necessary accessory uses shall be allowed in Mineral Extraction district only in conformance with an approved excavation and rehabilitation plan. The plan shall contain the following in the required number of copies.

a.

A detailed description of the method of operation of excavation and rehabilitation to be employed, including any necessary accessory uses.

b.

An excavation plan showing the areas to be mined with accompanying time schedules, fencing, depth and other pertinent factors.

c.

A detailed rehabilitation plan showing detailed proposed rehabilitation with time schedules, including finished contours, grading, sloping, types, placement, and amount of revegetation, after-use plans and any other proposed factors.

d.

A water report and evaluation prepared by a registered engineer analyzing the effect and/or feasibility of both ground and surface water.

e.

A drainage report and drainage plan prepared by a registered engineer with consideration of natural drainage, drainage during excavation and drainage after rehabilitation such that the proposed rehabilitation and excavation will have no adverse effect in excess of natural conditions (where applicable, the report should consider floodway and flood storage aspects).

f.

Any additional information as may be requested by the Community Development Department.

g.

Upon approval, the excavation and rehabilitation plan should be filed as a Planned Resource Development Plan with bonding and insurance deemed necessary by the City Council to insure compliance with both the excavation and rehabilitation plans as approved. Any change in either plan shall be prohibited unless amended by approval of the City Council after review by the Planning Commission.

h.

The procedure for consideration of any request change in the plans shall be the same as for a zone change.

6.

h.

The operator shall submit a route plan to the Director of Infrastructure & Public Works and receive permission to use for haulage any public right-of-way not designed for such haulage by reason of load limit, dust, right-of-way or pavement width, or other relevant factors. He or she may place reasonable restrictions on such right-of-way use.

i.

The floor of excavated pits, whether wet or dry, shall be left in a reasonably smooth condition.

j.

The operator shall not excavate, store, overburden or excavate material, or dike in such a manner as to increase any drainage or flooding on property not owned by the operator or damage to public facilities.

k.

Prior to starting excavation, the operator shall fence gravel pit operations with a V-mesh or chain link fence to a height of 72 inches topped with 3 strands of barbed wire canted at a 45 degree angle outward. The operator may fence the entire area immediately or fence only areas of excavation; however, no fencing shall be removed until rehabilitation has been completed.

D.

Flood Control District (FC).

1.

Intent. The Flood Control district is intended to protect areas that are susceptible to periodic or occasional inundation due to natural weather cycles, rare weather events, or changing weather and climate patterns. This district preserves the ecological functions of water courses, wetlands, and areas susceptible to floods and protects or limits any investments in and around these areas. The district implements the national Flood Insurance Program for the City of Brighton.

2.

Applicability. The Flood Control district can apply as an overlay district or as a special purpose district for areas designated on the official zoning map. In cases where it applies as an overlay district, the standards of the FC district override all standards and uses of the base zoning district that are contrary. In cases where it is applied as a special purpose district, the FC district standards apply, but should any change in the flood boundary or FC district occur, the property shall revert to the A/R zoning district standards, unless another district is specifically designated at that time.

3.

Uses.
