Steve,
See below for the seed mix that the City would like to use for re-vegetation in the non-irrigated areas of the park.
-----------------------------------------------------------------------------------------------------------------------------------
As supplied by Native American Seed of Junction, TX, the Contractor shall furnish and install a “Blackland Prairie Mix” of
native prairie grass to the designated disturbed areas. The seed application shall be at a rate of 8 pounds of seed per
acre and contain a diverse blend of native plants.
An approved equal mix of native prairie grasses from another supplier will be considered. Sample shall be submitted for
approval.
Reference: http://www.seedsource.com/catalog/detail.asp?product_id=2800
Contractor shall water the new seeding until germination and grass establishment.

Not what we're looking for, need a right of way seed mix , or native seed mix. I don't think he plans to hydromulch,
probably put it out with spreaders

John,
See below for a spec on seed mix and hydromulch. Let me know if you have something different in mind. Thanks

Seed mix
Goal: to establish a permanent Bermuda grass turf
Nurse Grass seed mix:
Perennial Rye: will die out or go dormant with +90° daytime temperatures; will come back in patches each fall/winter;
germinates quickly; will slow erosive conditions from becoming a problem
Common Bermuda: permanent turf grass; much slower to germination and establish; reasonably drought tolerant once
well established; full sun exposure conditions
APPLICATION
RATES:
Blend the seed mix together in the following ratio:
Perennial Rye: 3 lbs./1000 sf or 130 lbs/acre
Common Bermuda: 2 lbs/1000 sf or 85 lbs/acre
SUGGESTED METHOD:
Hydroseeding
1. Schedule work for periods of favorable weather.
2. Pre-Plant Weed Control has eradicated undesirable vegetation.
3. Protect all areas from excessive compaction when trucking plants or other material to the planting site. Existing
vegetation identified by the Engineer to remain, shall be protected from trucking operations during the course of
construction.
4. Hydromulching Operation:
a. Mixes shall be:
Bermuda seed (hulled) 85 lbs./acre
AND
Perennial Rye Grass 130 lbs./acre
Hydromulch fiber mulch 2000 lbs./acre
Commercial fertilizer 400 lbs./acre
Seed additive binder 100 lbs./acre
Water 3600 gallons
b. All hydromulched areas shall be installed by an approved hydromulch company.
c. The hydromulch operations shall be applied in the form of a slurry consisting of cellulose fiber, seed,
chemical additives, commercial fertilizer, and water. When hydraulically sprayed on the soil surface, the
hydromulching shall form a blotter-like groundcover impregnated uniformly with seed and fertilizer and shall
allow the absorption of moisture and rainfall to percolate to the underlying soil.
d. Preparation: The slurry preparation shall take place at the site of work and shall begin by adding water to
the tank when the engine is at half throttle. When the water level has reached the height of the agitator
shaft, full re-circulation shall be established and the seed added at that time. Fertilizer shall then be added,
followed by the fiber mulch. The mulch shall be only added to the mixture after the seed and the tank is at
least one-third (1/3) filled with water. All the mulch shall be added by the time the tank is two-thirds (2/3) to
three-fourths (3/4) full. Spraying shall commence immediately when the tank if full.
e. Application: The operator shall spray with a uniform, visible coat of slurry by using the green color of the
mulch as a guide. The slurry shall be applied in a sweeping motion, in an arched stream so as to fall like
rain allowing the wood fibers to build on each other until a good coat is achieved and the material is spread
at the required rate per acre.
f. Time Limit: All slurry mixtures which have not been applied within two hours after mixing shall be rejected
and removed from the project and disposed of at the Contractor's expense.
g. Protection: Special care should be exercised by the Contractor in preventing any of the slurry being
sprayed inside any reservoir basin or into drainage ditches and channels which may impede the free flow of
3
rain or irrigation water. Any slurry spilled into restricted areas shall be immediately cleaned at the
Contractor's expense, to the satisfaction of the Owner and Engineer.
h. Immediately following the application of hydromulch, the Contractor shall wash excess material from
previously planted materials and architectural features. Care shall be exercised to avoid washing or
eroding mulch materials from the area.
i. Equipment: Hydraulic equipment used for the application of the fertilizer, seed, and slurry of the prepared
wood pulp shall have a built-in agitation system and operating capacity sufficient to agitate, suspend, and
homogeneously mix a slurry containing not less than 40 pounds of fiber mulch, plus a combined total of
seven (7) pounds of fertilizer solids for each 100 gallons of water.
j. The slurry distribution lines shall be large enough to prevent stoppage and shall be equipped with a set of
hydraulic spray nozzles which will provide a continuous, non-fluctuating discharge. The slurry tank shall
have a minimum capacity of 1500 gallons and shall be mounted on a traveling unit, either self-propelled or
drawn by a separate unit, which will place the slurry tank and spray nozzles within sufficient proximity to the
areas to be seeded.
k. The hydraulic equipment used for pesticide applications shall consist of a clean 150 gallon minimum
capacity fiberglass tank with complete mechanical agitation. The pump volume shall be ten (10) gallons per
minute while operating at a pressure of 100 pounds per square inch (p.s.i.). Distribution lines shall be large
enough to carry the volume of water necessary for even chemical distribution. The spray nozzle must cover
a 15 foot wide swath, with a minimum output of five (5) gallons per minute (g.p.m.) at 80 p.s.i.
