Ammon City Council Meeting
Date 2/13/2025
Mayor and City Councilmembers:
Parks Capital Improvement Plan FY26-FY46 Adoption
Staff Presenting:
Tyler Draney, Parks and Recreation Director
Recommendation
-Staff recommends adoption of the Parks Capital Improvement Plan FY26-FY46
Summary of Analysis
1.This document is intended to be a guide to accomplish anticipated replacement and
development of amenities in existing parks.
2.In most instances, the order of operations is less important than establishing a funding pathway
to accomplish these goals in the given timeframe. Unexpected damage, infrastructure failures,
and community priorities will likely occur, changing individual project completion dates, but the
overall completion date of this CIP will remain the same.
3.The cost of each project reflects a projected annual inflation rate of 4%.
4.The annual funding request of $225,000/year provides stability for annual budgeting. Any
additional funds via developer contributions, grants, and donations will accelerate the timeline.
Financial Impact
-Sets a predictable annual expectation of funding requests for the Parks Department
-Request an additional ±$45,000 for Parks over FY25 for FY26-FY46 budgets
Motion
“I move to adopt Resolution XXXXXXXX Parks Capital Improvement Plan for fiscal year 2026
through 2046”

Mayor Coletti and City Councilmembers:
Density and Development
Summary of Analysis:
1.Current density standards:
•Hillside Residential east of 45th East up to 2.5 units per acre
•Low density 1-4 units per acre with 6 units per acre allowed in RS as infill development
•Medium density 8-12 units per acre with up to 8 units attached
•High density 16-20 units per acre
2.Medium and High-Density developments must meet the requirements in 10-5-27 (adopted
December 16, 2021)
3.Green space requirements for medium and high density are in code. Open space is regulated by
maximum lot coverage and open space requirements in zoning code and the Residential District
Use Matrix.
4.Net density requirements recently enacted will take time to see the effects
5.Current zoning entitlements as shown on the map can only be changed by a request from the
land owner
6.The Comprehensive Plan recommends a variety of housing types as a land use goal (Chapter 10,
pg. 21)
7.The Comprehensive Plan Future Land Use map shows primarily low-density housing
8.Sustainability requires variety of housing, commercial, and industrial areas

Adopted by 2018-005R. Amended by Resolution 2023-003R.
Chapter 10. Land Use
This section of the Comprehensive Plan lays out the policies to be used in Ammon’s future land use
decisions. This section also contains the future land use map. The future land use map is a graphic
representation of the policies within this chapter. The map is created by using the policies, existing land
use patterns, proposed transportation systems, natural features such as the foothills and flood hazard
areas/floodplains, population projections, and the ideas and opinions contributed during the citizen
participation process. The comprehensive land use map can be found at www.cityofammon.us . Since the
future land use map is a generalized representation of the following policies, the policies are controlling.
The policies outlined in this chapter are to be consulted and used when staff, the Planning and Zoning
Commission and the City Council are reviewing:
•Requests for zoning changes,
•Requests for annexations and initial zoning,
•Plans and expenditures for expansion of major infrastructure such as water and sewer trunk lines
and transportation facilities which encourage growth,
•Plans for new major infrastructure such as parks, schools, and fire stations which will channel
growth to certain locations, and
•Requests or investments in major public buildings such as city halls, libraries, recreation centers
or city center facilities.
Projected Population Growth
The Bonneville Metropolitan Planning Organization (BMPO) has projected an estimated growth rate of
1.88% annually from 2014 to 2040 for the metropolitan area in its 2040 Long Range Transportation Plan.
The U.S. Census Bureau estimates the 2016 population of Ammon at 15,252 (Table 8). According to the
U.S. Census Bureau, the population of Ammon was 17,694 in 2020. If this population is projected to 2040
using the BMPO estimated growth rate of 1.88%, the 2040 population of Ammon is projected to be
25,680. If the densities of Ammon do not increase beyond their 2016 densities, the amount of land
required to hold the 2040 population and businesses ranges from approximately 3,900 acres to 4,700
acres. Today Ammon contains 4,831 acres, of which almost one-half is vacant. Although it appears as if
the future growth until 2040 may be accommodated within the present boundaries of the city, not all of
this vacant land may be easily or economically developed. Therefore, it is likely future annexations may
be required to ensure both public and private investments are made in locations where private investments
and public costs, including maintenance, are economically sound.

The area of impact contains over 11,000 acres and has sufficient land for growth beyond 2040. However,
as with the presently annexed lands within Ammon, not all lands within the area of impact may be
suitable for economic and efficient future municipal development. As Ammon grows into its area of
impact, the natural features of the land, proximity to the existing infrastructure, the cost of maintenance of
existing or proposed public facilities, the cost of development, and impact on neighboring land uses
should be considered prior to approval of annexation and new development.

Ammon’s land use goal should be to foster a community which continues to recognize and respect its
rural roots yet provides a variety of housing types and styles for its residents; encourages shopping
opportunities for the region, community, and neighborhood; continues to support and enhance the
infrastructure necessary to work and live successfully in the 21st Century; wor ks to attract tech and
professional businesses to the community; uses its natural features for open space and recreation; and
through a public/private partnership, builds a city center or gathering place which provides a walkable
environment of mixed-uses including community event space, small shops, public buildings, and mixed
housing types housing and offices.
Policies Based on Existing Land Use Patterns
The land use policies and, therefore, future land use map reflect these existing patterns in land use in Ammon:
1. Regional and community commercial uses line 25
th East and portions of 17 th Street, one a major
ar terial street and the other a minor arterial street.
2. In limited and newer locations, high-density residential uses buffer low-density residential uses
from commercial uses (Figure 3).
3. Community and neighborhood commercial uses have been channeled to the intersections of major
or minor arterial streets.
4. Secondary school facilities buffer residential uses from regional commercial uses.
5. Elementary schools are generally located in the center of the residential neighborhoods they
serve.

Adopted by 2018-005R. Amended by Resolution 2023-003R.
6. In certain limited locations, parks reflect natural features or limitations to development.
7. Development on the foothills is generally proposed to be lower density; therefore, residential
densities generally decrease further from regional commercial land uses and 25 th East. Densities
decrease as one travels farther from commercial land uses.
8. Residential densities are predominantly less than four units per acre.
Ammon’s land use policies and strategies should be to accomplish the following:
1. In new developments, density declines as development moves further away from arterial and
collector streets, with higher densities transitioning to lower densities.
2. Recognize natural features, such as topography, floodplains, drainage areas, and wildlife
corridors, may be amenities to development and may be used to enhance the community and
neighborhood (Figures 4 and 5).
3. Encourage completion and submission of site analysis, including topography, hydrology
including water table, soil suitability, drainage patterns, slope and similar natural features, prior to
submission of preliminary development designs.
4. Protect life and property from natural hazards through, but not limited to, identification of such
areas, open space and park plans and acquisition, reduction of densities in such areas, and
enforcement of construction codes.
5. Preserve and protect the major transportation corridors in Ammon and enhance the experience of
the visitor and resident by ensuring such corridors are attractive and inviting.
6. Protect the public investment in major transportation corridors through land use decisions which
discourage strip commercial development; discourage mid-block commercial uses except on
designated arterial roadways; require, when necessary due to anticipated traffic demand, traffic
studies and related improvements; control highway access; and use landscaping to beautify as
well as control traffic movement.

AND MINOR ARTERIAL STREETS.

7. Recognize the benefits of different residential street layouts and encourage the use of the one
which is most beneficial to the public in the proposed location. Grid layouts disperse local traffic,
enhance walkability, and connect neighborhoods. Circular street layouts reduce costs for
construction and maintenance, reduce the amount of impermeable cover, discourage through
traffic, and encourage layouts which protect sensitive lands. Cul-de-sacs share the benefits of
circular street layouts but should be used only when staff, Planning and Zoning and the City
Council agree it to be in the best interest of the residents. Cul-de-sacs, while providing benefits,
also provide significant issues when considering parking and snow removal.
8. If developments are constructed with circular street layouts or cul-de-sacs, pedestrian pathways
should be provided to ensure neighborhood connectivity and to ensure convenient pedestrian
access to schools, parks, and open space. Such paths might also provide access to small
commercial facilities needed for daily goods.
9. Encourage infill development to ensure development is compact, economic and efficient.
10. Establish land use patterns which build on existing water and sewer facilities.
11. Link homes, schools, parks and shopping areas with bicycle and pedestrian paths. Consider using
sensitive lands in such linkages.
12. Continue to require adequate storm water management for new development and explore methods
to safely allow multi-use of such facilities.
This sketch illustrates one approach to
steep slopes and a floodplain. The
private lots encompass a portion of the
steep slopes and are partially covered
with a no-build easement. The
floodplain may be owned and included
as a part of a platted lot with a no-
build easement within the floodplain
portion, in common by the homeowner
association or is a natural park owned
by the city. Another approach is to
extend the lot lines to the stream and
encompass the steep slopes and the
floodplain within the no-build
easement. SOURCE: Based on Figure 25
from Land Development 2 .

13. Develop site and design review standards to increase depth of yards adjacent to major streets and
railroad. Encourage design treatments such as building orientation, height limitations, fencing,
and landscaping to reduce land use conflicts, especially adjacent to major streets, the railroad, or
heavier commercial and industrial areas.
14. To ensure open space on sensitive lands or to reduce conflicts with neighboring land uses,
consider encouraging clustering of homes. Clustering reduces the cost of site preparation,
provision of streets and utilities, and maintenance of streets and utilities. Housing clusters of 40
to 80 homes are safer for residents and offer the developer an economic unit.
15. Locate commercial and higher density residential uses at or near intersections of major roads,
provided the layout of such uses allows sufficient land for safe ingress and egress not interfering
with traffic flow near intersections.
16. Explore the development of a tech/research park to increase employment opportunities in
Ammon.
17. Encourage land uses which generate major traffic to locate near major and minor arterial streets,
provided the design of such uses reduces the impact on the street system by controlling access.
18. To retain the rural nature of Ammon, discourage lot splits in established subdivisions and protect
existing farm operations from land use conflicts with proposed developments.
The policies by land use categories found on the future land use plan are as follows, pursuant to
regulations in Title 10 of City Code:
High Density Residential
1. The maximum density for high density residential is twenty (20) dwelling units per acre.
2. High-density land uses are proposed adjacent to or near arterial roadways and commercial areas.
High-density developments not located near an arterial roadway are not recommended.
3. High-density residential uses should be located within walking distance of commercial
developments.
4. High-density residential uses offer flexibility in design. Parking, garages, storm water retention
areas, landscaping, outdoor amenities, and larger yards can be used to buffer the dwelling units
from the noise of neighboring land uses. Such buffering techniques should be encouraged in new
high-density development.
5. Developments built at these densities should be walkable and, when available, can be served by
transit. Site design should ensure such developments have walkways which connect housing with
neighboring uses such as shopping areas, offices, schools, churches, and public facilities.
6. High-density developments that do not provide walking access to essential amenities, such as
grocery stores and retail establishments, are not recommended.
7. A mixture of housing types should be encouraged that may include, walk-up buildings, twin
homes and/or duplexes, town homes and/or row houses, and condominiums and/or apartments
within one development which broadens the occupant mix, fosters a neighborhood environment,
and reduces the monotony of multiple buildings of the same exterior design and scale. If done on
a smaller scale or mixed, different housing types do not overwhelm one another.

2018 City of Ammon Comprehensive Plan
26
Adopted by 2018-005R. Amended by Resolution 2023-003R.
8. To create a walkable neighborhood, destinations should be within ¼ mile or five minutes walking
time, sidewalks in residential areas should be at least five feet in width and wider in commercial
areas, sidewalks should be separated from public roadways by a six- to seven-foot-wide planting
strip, and vehicle speeds should be 15 to 25 MPH. Traffic calming measures such as narrow
traffic lanes, gateways, landscaping, and corner flares also create a pleasant environment.
9. High density residential should be located near or provide for transit pickups as they are
available. As high-density developments are created in the City, there should be a review of the
current transit stops for the potential of offering pickup on site or near the high density
developments
10. Clustering buildings also offers the ability to buffer dwellings from major roads and neighboring
land uses as well as offering an opportunity to create open space on sensitive lands.
11. Each living unit in a high-density residential development should be individually platted to
encourage homeownership.
Ammon City Council February 13, 2025 Page 15 of 42
2018 City of Ammon Comprehensive Plan
27
Adopted by Resolution 2018-005R
Medium Density Residential
1. The maximum density for medium density is twelve (12.0) dwelling units per acre.
2. Town homes offer flexibility in design. Parking, garages, storm water retention areas,
landscaping, fencing, outdoor amenities, and larger yards can be used to buffer the dwelling
units from the noise of neighboring uses. Such buffering techniques should be encouraged in
proposed medium density development.
3. Clustering buildings also offers the ability to buffer dwellings from major roads and neighboring
land uses as well as offering an opportunity to create open space on sensitive lands.
4. Medium density is envisioned to consist of single-family attached townhomes. Often homes
built at such densities will be a buffer between commercial or residential developments of
higher densities and single-family homes on large lots or will be located on entrance ways to
residential subdivisions.
Low Density Residential
1. The maximum density is six (6.0) units per acre for detached housing.
2. Arterial corridors east of 45th E along 45th E, 1st Street, Sunnyside Road, 49th South, and
65th South shall not exceed 500 feet from the arterial, measured from the Right-of-Way.
3. Low-density residential may consist of single-family detached homes on larger sized lots
with wider side yard setbacks. Low density may also consist of single-family detached homes
on smaller lots as well as single-family attached twin-homes. Other creative solutions may
exist in low-density developments, provided the maximum density is not exceeded.
Hillside Residential
1. The maximum density is two and a half (2.5) units per acre.
2. Hillside residential consists of single-family detached homes on larger sized lots with wider
side yard setbacks.
3. This designation is used for development east of 45th East, excluding the arterial corridor as
defined in Low Density Residential.
Institutional Uses (Schools and Churches)
1. Institutional uses such as elementary schools and churches should be located in residential
neighborhoods on collector streets. Secondary schools should be located near minor or major
arterial streets.
2. Shared use agreements should be pursued with schools to allow the playgrounds to be used
outside of school hours by the surrounding neighborhood as park and open space.
3. A line of communication should be maintained between school and city personnel to regularly
discuss population projections and anticipated growth patterns, needs for school facilities, and
impacts of school location on municipal utilities and facilities. Discussions should also include
potential requirements by the City as placement of schools are considered.

Heavy Commercial
Table 10. shows the general characteristics associated with heavy commercial developments. Not all
numbers in this table fit eastern Idaho. These numbers are based on national numbers. Locally the market
area is likely to be larger than found in the tables below while the population served is often smaller. As a
result of a larger market area and longer distance to the shopping centers both the minutes of driving time
and the distance in miles will likely be increased for this market.

1. Regional and super-regional shopping areas should be located on major and minor arterial
streets (Figure 6).
2. Access from such shopping areas shall meet the standards of the Bonneville Metropolitan
Planning Organization Access Management Plan, July 2012.
3. The clustering of major commercial developments should be encouraged at intersections. The
continuation of commercial development along the frontage of arterial roadways should
maintain low access egress for businesses along the frontage at major points or roadway
intersections. A shared access traffic aisle should be required throughout developments along
the entirety of the arterial roadway. Landscaping within all commercial developments should
meet the requirements of Ammon Code Title 10, Chapter 5, Section 24.
4. Require perimeter landscaping for new commercial development. Landscaping not only
reduces the visual impact of parking lots; it also directs traffic movement through the parking
area and defines access to the neighboring street network. The Urban Land Institute states a
reasonable amount of landscaping is 10% of the total site and 20% of the parking area. Such
landscaping can be used for storm water retention and snow storage.
5. Shopping areas should buffer adjacent residential areas from the lights and noise of commercial
areas by landscaping, fencing, and building placement.
6. Professional offices offer an effective buffer between major commercial areas and apartments
and homes. If high density residential is located next to major commercial areas, the location of
parking areas, garages, landscaping and fences for such residential uses should buffer the
dwelling units from the noise and light of the commercial areas.

Community and Neighborhood Shopping Areas and Professional Offices
As with the table above under regional shopping areas, not all the numbers fit eastern Idaho. These
numbers are based on national numbers. Locally the market area is likely to be larger than found in the
tables above while the population served is often smaller. As a result of a larger market area and longer
distances to shopping centers, both the minutes of driving time and the distance in miles will likely be
increased for this market.
However, the table still provides a framework for commercial locations and provides fairly realistic
numbers for the site area necessary for stores and shopping centers (Table 11).

1. Neighborhood centers should be located in clusters at the intersections of arterial streets. Since
they serve the immediate residential area, they may be located at intersections with minor
arterials or with major collectors.

Adopted by 2018-005R. Amended by Resolution 2023-003R.
2. If neighborhood centers are located at the major arterial intersections, pedestrian access to the
neighboring residential areas should be provided to allow residents to shop without having to use
the arterial street to access the shopping area.
3. Access from such shopping areas shall meet the standards of the Bonneville Metropolitan
Planning Organization most current Access Management Plan.
4. Shopping areas adjacent to residential areas should be required to use exterior lighting designs
that shield the residential area from light pollution, as well as using fencing and landscaping to
reduce noise from commercial areas.
Industrial
1. When reviewing requests by heavy industries that may have major off-site impact costs and
infrastructure needs beyond what is available at the time of the request, those cost should be
included as part of any approval and passed on to the developer as a required development cost.
2. When zoning for industrial uses, consider the predominant wind patterns from the southwest.
3. Locate industrial lands near major arterials with good access to highways, and/or adjacent to
railroad facilities. Regional airport access is available by accessing the east and west arterial
roadways and accessing either I-15 or Highway 20.
4. Buffer residential areas from industrial lands by roadways, office and shopping areas, open space,
landscaping, berms, and fencing. Such buffering should be tailored to the industrial use. The
buffering required for a food processing plant is likely to be different than the buffering required
for a research laboratory or light assembly plant.
Parks and Open Space
1. The existing parks are shown on the future land use map as parks.
2. Future parks are shown symbolically on the future land use map to suggest a park or open space
needed to serve the neighborhood as it develops.
3. Sensitive lands such as floodplains, wetlands, steep slopes, and drainages, plus exhausted gravel
pits, may be shown as open space.

Ammon City Council Work Session
February 13, 2025
Mayor Coletti and City Council Members:
School Development Standard
Staff Presenting:
Cindy Donovan – Planning Director
Heather McBride – Assistant Planner
Recommendation:
- Staff recommends adopting a students per acre requirement for minimum school site size
- Staff recommends adopting a standard that considers traditional public, charter, and private
schools
Summary of Analysis:
1. Title 10, Chapter 41 PSC Parks, Schools, and Churches Zone was approved by the City Council
and added to the Ammon City Code on March 16, 2023
2. Part of adopting PSC was to replace the conditional use overlay that was previously used for
schools in residential areas
3. Planning resources referred to the North Carolina Public Schools guide “The School Site Planner”
for school lot designs, including minimum lot size – this standard requires more space than what
is traditionally in this area likely due to the difference in school design between east and west
coast areas
4. The attached research summary shows three different standards, minimum required acreage
based on the standards and number of students, students per acre comparison between the
standards, and how using a 65 students per acre standard would influence private and charter
schools in the area
5. Based on the research summary, the most restrictive student per acre from the standards is 37
students/acre
6. Based on the research summary, the least restrictive student per acre from the standards is 65
students/acre
7. Schools are allowed in all commercial and industrial zones. Schools looking for a higher use
would locate in commercial/industrial areas rather than PSC in residential areas.
8. Building size is limited by occupancy, fire code, and building code
