RE: Phased Revegetation Plan for Bozeman East Apartments
Introduction
The Bozeman East Mixed-Use Development is located off of Tschache Lane on Lot 5 of the Bridger
Peaks Village Subdivision. Farran Realty Partners LLC has planned to construct four apartment
buildings, a clubhouse, a commercial retail space and outdoor recreation space on this property. The
project will be constructed in a phased manner, and this revegetation plan has been developed to
ensure site stabilization and weed prevention in the interim phase prior to final construction. Once the
site is completely developed, the final landscaping will be installed. This information should be used
in conjunction with a Stormwater Pollution Prevention Plan (SWPPP).
Approach
Construction schedule
The entire site will be cleared, grubbed, and graded per design. The proposed phasing sequence will
begin with Building 4/D and, following a two week off-set, Building 3/C will begin. Buildings 2/B and
1/A would start approximately 6 months to a year after Starting Buildings 4/D and 3/C. There will be
a total of 2 phases. See the attached Exhibit 6 – Master Site Plan Narrative.
Planting schedule
In order to stabilize soil and prevent noxious weed infestation in Phase 2, the area will be seeded with
a hardy dryland seed mix. Seeding can occur in either the spring (April through early June) or fall
(September through October). If the area is seeded in the fall, it is also recommended that straw
mulch be laid down to help secure the seeds in place and provide for stabilization during the winter
months.
Seed Mix
The following is a hardy dryland seed mix developed by the landscape architect on the project.
Plant Percentage
Fairway Crested Wheatgrass 30%
Hard Fescue 30%
Slender Wheatgrass 15%
Sodar streambank wheatgrass 10%
Thickspike wheatgrass 10%
Brome 5%
Provide fresh, clean and dry new seed with not less than 80% germination, not less than 95% pure
seed, and not more than 0.5% weed seed. Apply dryland seed mixture at a rate of 10-12 lbs/acre, drill
seed.
Smaller disturbed areas can be temporarily stabilized with the use of mulch or weed mat. Both of
these techniques will create soil stabilization and provide competition against weed infestation.
Final landscaping
Final landscaping will be established based on the landscaping plan, included in this submittal.
