RE: Phased Revegetation Plan for Boulder Creek Apartments
Introduction
The Boulder Creek Apartments are located off Abigail Lane on Lots 1 & 2 of Block 5 of the Boulder
Creek Subdivision. Rosa Johnson Development LLC has planned to construct three apartment
buildings and one future apartment building. 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. There will be a total of 3 phases.
See the attached C200 and Exhibit 1 – Master Site Plan Narrative.
Planting schedule
In order to stabilize soil and prevent noxious weed infestation in Phases 2 & 3, 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.
