11-05-02: Conservation Overlay Districts


1. Generally:

A. Purpose: To preserve the character of selected neighborhoods and to protect unique areas of the city from inappropriate development. A conservation overlay district is usually applied to residential neighborhoods with certain identifiable attributes embodied in architecture, use, urban design, geography, or history. A conservation district can be used to protect neighborhoods from changes that would otherwise be allowed by the underlying zoning.

B. Designation Of Conservation Districts: Conservation districts shall be designated by ordinance. Neighborhoods or areas selected for consideration for a conservation district designation shall meet at least one of the following criteria:

(1) Has a distinctive character with identifiable attributes embodied in architecture, use, urban design, or history that make it a unique and integral part of the city's identity; or

(2) Has a recognized neighborhood identity and a definable physical character that may have a high artistic value or a relationship to urban centers or historic districts and that makes the area's conservation significant to the city's history or function.

C. Establishment Of Conservation District:

(1) Conservation district provisions may apply additional requirements or allow exceptions to the standard regulations of the base zone.

(2) Prior to adoption of a conservation district ordinance in a district that may be of historic significance as determined by the Director, the HPC shall have the opportunity to review and comment on the proposed ordinance.

(3) Prior to recommending an area for designation as a conservation district, the PZC shall:

(a) Conduct any necessary studies, research, or investigations; and

(b) Assess neighborhood and landowner support; and

(c) Prepare a report containing recommendations.

(4) See Section 11-03-04.3, Rezone for procedures to establish a district.


2. Hyde Park Conservation District:

A. Purpose: To maintain the historical commercial district as a functioning community asset and maintain a mix of commercial, office and residential uses. The district encourages land uses that are determined to be key to the district's long-term health and sustainability.The district regulations are intended to protect the historical and architectural character of Hyde Park and establish parking standards for this area. Parking requirements are on a graduated scale for certain uses to encourage street-level retail and restaurants as well as second story office uses. Shared parking is encouraged to reduce the need for surface parking.

The maximum animal density for small animals shall be one animal unit per one-quarter acre of land area behind the front of the principal dwelling.The area used for calculating the allowed number of small animals shall not include land occupied by any building not used for housing said animals.For areas of land different from one-quarter acre, the one animal unit: one-quarter acre ratio shall be applied to determine the allowed number of animals.

iii. The keeping of chickens in conjunction with the keeping of large animals is an exception to animal density standards. Up to six chickens may be kept simultaneously and in addition to the large animals allowed per lot based on the density standard.

iv. No more than one rooster shall be kept on any single parcel, regardless of the size of the parcel.

(f) Site Plan: As deemed necessary, the Director may require the owner or resident to submit a site plan, subject to approval, for the purpose of determining the amount of land available on a particular site for the keeping of animals pursuant to the standards of this section.

(g) Setbacks For Concentrated Feeding Areas, Buildings, And Pasture And Reserve Areas: Concentrated feeding areas and buildings housing animals shall be located behind the front of the principal dwelling and a minimum of ten feet from all property lines. Fully enclosed buildings must comply with the setback standards for the base zone and, therefore, may in some cases be set back less than ten feet from the property line.Pasture or reserve areas shall be located behind the front of the principal dwelling, and may otherwise be located at the side and rear property line.

A BMP is defined as a practice or combination of practices that are the most effective, practicable means of preventing or reducing the amount of pollution generated by non-point sources to a level compatible with water quality goals. Any owner or resident intending to keep livestock and other animals pursuant to this section shall implement the following BMPs:

i. Fencing: Enclose one or more areas on the site as needed with a permanent fence or structure to function as a barrier to livestock and other animals to prevent access to and protect streams, canals, and ditches from trampling, erosion, and contamination.

ii. Filter Strips For Streams, Canals, And Ditches: Maintain a gently sloping strip of ground cover vegetation to filter runoff from the portion of the site occupied by animals.Filter strips shall distribute waste matter uniformly across the high end of the strip and allow waste to flow through and across the strip and shall promote the filtering of nutrients, runoff water, and other material through the grass so that they can be absorbed by the soil and ultimately taken up by the plants.

iii. Runoff Control System: Employ a combination of practices to prevent animal waste runoff to surface water and adjacent properties. Practices may include diversion of runoff from the lot, roof runoff systems, lot shaping, settling basins, and filter strips or buffer areas.

iv. Liquid And Solid Waste Management System: Employ a system for managing liquid and solid waste in a manner that: a) ensures fecal matter and other solid wastes do not create or promote nuisances, odors and disease-carrying insects and animals, and b) does not degrade air, soil, or water resources. The appropriate system will typically include the frequent spreading of liquid and solid waste, composting of manures, and off-site disposal.

v. Additional BMPs: Additional BMPs shall be required if those BMPs listed above are shown to be ineffective.The owner or resident can consult the following agencies for additional technical assistance:Ada Soil Conservation District Natural Resources Conservation Service (Home*A*Syst/Farm*A*Syst Program), Idaho Soil Conservation Commission, The University of Idaho Extension Service, and the Boise Public Works Department.

(k) Periodic Assessment: At three-year intervals the residents and property owners in the S District and the Director shall assess the impact and effectiveness of the standards of this section in protecting residents and owners of the district and those outside the district from unwanted impacts.

(5) Performance Monitoring: The applicant shall monitor the performance of constructed enhancements for a minimum period of 18 months unless otherwise fixed by the PZC. Acceptable performance shall be judged by comparing measured values to standards that were previously agreed-upon.

11-05-07: Special Purpose Overlay Districts


1. Airport Overlay Zone District: [Reserved]

11-05-08: Specific Plan Districts


1. Purpose: Specific plan districts provide a means to modify or create new zoning regulations for unique areas and developments where other conventional zoning mechanisms cannot achieve the desired results. Specific plans shall implement and be consistent with the Boise City Comprehensive Plan land use map and policies.


2. Scope:

A. Examples Of Specific Plans: Specific plans may take the form of mixed use districts and planned communities or planned development. Each specific plan has its own non-transferable set of regulations. The regulations may include: zoning standards, design guidelines, site plan,infrastructure plan, phasing plan and other elements. Specific plans are adopted into the zoning code by ordinance and become either the base zone or an overlay zone for the property.

B. Basic Specific Plan: A specific plan may be an overlay zone that modifies or expands the base zone to allow different dimensional standards, streetscape treatments, and architectural designs. Every basic specific plan should include a detailed site plan and illustrations.

C. Complex Specific Plan: A specific plan may also address a very large site of hundreds of acres. In this case, the specific plan may include many different chapters with detailed standards for the issues addressed in each chapter. For example, a large planned community specific plan may include a detailed land use plan with lotting patterns, building envelopes, and street networks. Detailed zoning standards could be included that address setbacks, building heights, mix of uses, and parking ratios. A design chapter could describe materials, architectural styles and sign programs. A Landscape Section could address common open space areas with a plant palette and irrigation plans. A transportation chapter could include roadway cross sections and streetscapes, pathways, or a public transportation or transportation management program. An infrastructure chapter could address the location, sizing and timing of sewer, water, fire and other facilities. An environmental chapter could address water quality, riparian protection, revegetation of graded slopes and similar issues. A phasing chapter could identify how the construction would proceed and at which point in time certain infrastructure elements would be installed. A review process chapter could describe the specific review and approval process for individual phases within the project. In this case, the specific plan might constitute all aspects of project approval short of subdivision final plat approval.


3. Land Use Controls: The type of uses and amount of development in a SP district shall be as established by the specific plan. Pre-existing legal non-conforming uses shall be permitted in a SP district. Any permitted or conditional use may be included in a specific plan district.


4. Initiation: An amendment may be initiated by a property owner or authorized agent, the PZC, or the Council. If the property is not under a single ownership, the majority of ownership shall join in the application, and a map showing the extent of ownerships shall be submitted with concept plans and materials. For the purposes of this Section, a majority of ownership shall be defined as either 75 percent of the affected owners or 75 percent of the affected land area. For projects larger than 200 acres, a neighborhood scoping meeting, per Section 11-03-03.2, between the applicant and the City of Boise shall be conducted prior to application submittal to determine which supporting materials and specific plan elements shall be appropriate and required for the proposal.


5. Minimum Area Standards: The minimum area of a SP district shall be two acres or one city block.


6. Required And Optional Elements: A specific plan shall include some or all of the following elements:

A. A map depicting the proposed pattern of land use and open space, with acreage by land use type.

B. A written document, describing in detail the zoning standards for all land uses including but not limited to: setbacks, height, density, parking, floor area ratios, landscaping,signage, lighting requirements, and similar issues. When the existing base zone is left in place and the specific plan becomes an overlay zone, this document need only address the elements that differ from the standards of the base zone.

C. A map depicting the proposed street and lot pattern.

D. A map depicting the location and configuration of all infrastructure/public services and facilities proposed within the specific plan district. Such facilities include but are not limited to roads, sewers, lift stations, drainage facilities, fire stations, police substations, parks, libraries, communications equipment, and similar facilities.

E. A phasing plan for development of all uses and supporting infrastructure.

F. A capital improvement program for all infrastructure.

G. A written and illustrated document, describing in detail any design guidelines for the development, including but not limited to: architectural style, materials, colors, themes, streetscapes, public realm elements, and similar issues.

H. A written document describing the review, approval, and amendment process for all proposed uses and phases in the project.

I. Other elements such as grading plans, wildlife mitigation plans, open space management plans, hazardous materials remediation plans, etc.


7. Procedures: The PZC shall consider an application for rezone to a SP District and shall at the same time consider the proposed Specific Plan accompanying the application.

A. Required Findings: The PZC shall forward a recommendation to the Council based on findings that the specific plan:

(1) Is consistent with the goals, objectives and policies of the Comprehensive Plan, with particular emphasis placed upon those polices related to diversity of housing, mixing and integration of uses, pedestrian and transit design, level of service provision and environmental protection;

(2) Is compatible with surrounding development and properly integrates land uses and infrastructure with adjacent properties;

(3) Includes adequate provisions for utilities, services, roadway networks and emergency vehicle access; and public service demands will not exceed the capacity of existing and planned systems; and

(4) Will enhance the potential for superior urban design and land use in comparison with development under the base district provisions that would apply if the specific plan were not approved.

B. Zoning Map Designation: A SP district shall be noted on the zoning map by the designation "SP," followed by the number of the SP district based on order of adoption. The SP may be either appended to the base zone as an overlay, or may be the primary zoning with no other base zone.

C. Status Of Specific Plan: A specific plan adopted by ordinance of the Council shall be administered as prescribed by the Council and as established by the provisions of the specific plan for review, approval, and amendment. Adopted specific plans shall be listed by name and number in Section 11-05-08.8 of this ordinance and shall be maintained on file in the Director as a bound and printed document.

D. Review Of Plans: Application for building permits for projects in a SP district shall be accepted only if the project plans are consistent with the standards of the adopted Specific Plan.


8. Adopted Specific Plans: Adopted specific plans are included in Chapter 11-13.
