landscaping is to be installed with future buildings. Landscaping will be watered with City water.

Section 2
If this project is not part of a site plan, the following developments must follow the Landscape and Irrigation
Design Requirements listed below:
• Single Household or Townhome
• Duplex, Triplex, Fourplex
Landscape and Irrigation Design Requirements:
Select either A) or B):
A) Turfgrass areas may not exceed 35 percent of the total landscaped area or 400 square feet,
whichever is more. Remaining landscaped areas must consist solely of low and/or very low water
use vegetation (plant factor of 0.3 or less) and landscape design elements such as rock mulch and
wood mulch except for raised beds dedicated to edible gardens. Refer to the City of Bozeman plant
list for acceptable plant types. It is strongly encouraged to install at least 50% native plants in the
overall landscape.
B) In lieu of compliance with the above requirement, for those seeking more landscape design
flexibility, a landscape water budget demonstrating that the landscape does not exceed an average
annual irrigation demand of 10 gallons per square foot may be provided. Project applicants pursuing
the water budget approach must provide a completed Water Budget Calculator as outlined in the
City’s Landscape and Irrigation Performance and Design Standards Manual with this form.
Additional requirements:
At least 60 percent of the site area not included in footprints of buildings or structures, sidewalks, driveways,
walkways, or other hardscaped areas, such as decks or pervious pavers, must be landscaped and maintained
39
with some combination of vegetative understory plantings, such as shrubs, perennials, turfgrass, creeping
or rooting groundcovers, or other living plants (excluding weeds). The installation of at least 50% native
plants in the overall landscape is encouraged.
Landscaped areas must have at least 6 inches of topsoil depth throughout the entire planted area. The
building footprint and all areas within 5 feet of the actual building are exempt from the topsoil requirement.
The topsoil requirement may be met by implementing one of the following methods prior to planting:
- Amend existing topsoil at a rate of 4 cubic yards of compost/1000 square feet;
- Amend existing topsoil based on the recommendations of a soil test; or
- Import topsoil to achieve a minimum depth of 6 inches of topsoil.
A minimum three-inch layer of mulch must be applied on all exposed soil surfaces of planting areas except
for turf areas, creeping or rooting groundcovers, or direct seeding applications where mulch is
disadvantageous.
Rock mulch is discouraged around private trees and prohibited around public, boulevard trees. Public,
boulevard trees must have a 3’ diameter wood mulch ring 3”-4” in depth.
A minimum of 75 percent of trees shall be drought adapted or have a plant factor of 0.3 or less and must
follow the diversity table below:
Deciduous and Evergreen Tree Plant Diversity Table
Number of Trees Maximum % of Single Species
1-5 Can have 100% of one species
6-10 Maximum 50% of any one species
11-20 Maximum 33% of any one species
21+ Maximum 25% of any one species
Backflow prevention devices are required (compliance with local plumbing code).
Irrigation controllers labeled by U.S. Environmental Protection Agency’s WaterSense® Program must be
installed.
Sensors (rain, freeze, ET, soil moisture, etc.), either integral or auxiliary, that suspend or alter irrigation
operation during unfavorable weather conditions or when sufficient soil moisture is present are required.
Overhead irrigation must consist of Multi-Stream, Multi-Trajectory (MSMT) nozzles, or an approved equal,
and/or rotors.
Overhead irrigation must use a 6 inch minimum riser.
Sprinkler heads must be spaced 2 inches minimum from hardscape edges.
Irrigation systems must be designed to properly address hydrozoning in the landscape.
Drip irrigation must be used outside of lawn areas where irrigation is installed.
Areas less than 8 feet wide must be irrigated by drip irrigation. Overhead irrigation is prohibited in areas
less than 8 feet wide unless only used for temporary establishment.
Operating pressure of the irrigation system must meet manufacturer’s recommended operating pressure.
40
Trees must be on a separate irrigation valve(s) from other plant types to allow for a unique watering schedule
during drought related outdoor watering restrictions. Drip irrigation, such as emitters, root watering
systems, or bubblers, must be used to irrigate trees.
Irrigation pipe installed under hardscape surfaces must be sleeved in a rigid pipe.
Adjacent boulevard(s) must comply with these Landscape and Irrigation Design Requirements and current
boulevard tree requirements.
