400 Ibs. per acre (16-20-0) commercial fertilizer: 16-20-0 shall be a commercial
grade pelleted or granular, uniform in composition, dry, free-flowing and labelled
with specific N-P-K rating of (16-20-0).
200 Ibs. per acre Iron Sulphite
140 Ibs. per acre Ecology Control M-Binder (per manufacturer's
recommendations).
Non-irrigated Hydroseed Mix:
Artemisia California - 3 Ibs./acre
Batis Maritima - 3 Ibs./acre
Cressa Truxillensis - 4 Ibs./acre

TOTAL - 41.5 Ibs. seed/acre
Vegetation Restoration (Hydroseeding) - 2 of 4
The Rhus Integrifolia shall be seeded only on the steep slope and areas of higher elevation.
No planting of this species shall occur adjacent to wetland areas.
E APPLICATION
Do not hydroseed in any areas contaminated by other trades. All such occurrences shall be
reported to the District Engineer before commencing work.
E-1 Preparation
Layout hydroseed area locations. Stake locations, outline areas with gypsum, and secure
District Engineer's acceptance before start of hydroseed work. Make minor adjustments as
may be required.
Moisten prepared hydroseed areas before planting if soil is dry. Water thoroughly and allow
surface moisture to dry before commencing work. Do not create a muddy soil condition. Do
not hydroseed on sealed or crusted soils.
E-2 Hydroseeding Procedure
The Contractor shall examine related work including graded surfaces before proceeding with
any work and inform the District Engineer, in writing, of conditions which may prevent the
proper execution of this work.
Failure to report unsuitable conditions to the District Engineer will constitute acceptance of
responsibility for the performance of any additional work caused by the unsuitable conditions
at no additional cost to the District.
All materials shall be standard, approved first-grade quality, and in prime condition when
installed and accepted. Any commercially processed or packaged material shall be
undisturbed and delivered to the site in their original containers, unopened, bearing the
manufacturer's guaranteed analysis.
E-3 Hydromulching
The hydromulching shall be applied in the form of a slurry consisting of organic soil
amendments, commercial fertilizer, and other chemicals specified. When hydraulically sprayed
onto the soil, the mulch shall not form a blotter-like material. The spray operation must be
so directed that the slurry spray will penetrate the soil surface as to drill and mix the slurry
components into the soil, this ensuring maximum impregnation and coverage.
E-4 Preparation of Hydroseeding Mixture
The slurry shall be prepared at the site, and its components shall be mixed to supply the rates
of application as per specifications.
Slurry preparation shall begin by adding water to the tank when the engine is at one-half
throttle. When the water level has reached the height of the agitator shaft and good
recirculation has been established, the fertilizers shall be added to the mixture.
The engine throttle shall be open to full speed when the tank is Vfc filled with water. All
organic amendments, fiber, and chemicals shall then be added by the time the tank is 3A full.
At this time, the seed mix shall also be added and not before this time.
Vegetation Restoration (Hydroseeding) - 3 of 4
Spraying shall commence immediately when the tank is full and the slurry mixed.
E-5 Time Limit
The hydromulching slurry components are not to be left in the hydromulch machine for more
than two hours due to seed destruction. If slurry components are left for more than two
hours in the machine, the Contractor shall add 50% more of the originally specified seed mix
to any slurry mix which has not been applied within two hours after mixing. The Contractor
shall add 75% more or the original seed mix to any slurry mixture which has not been applied
eight hours after mixing or it shall be rejected and disposed of off-site at the contractor's
expense.
E-6 Protection
Special care is to be exercised by the contractor to prevent any of the slurry from being
sprayed onto any hardscape areas including concrete walks, fences, walls, building, etc. Any
slurry sprayed onto these areas shall be cleaned off at the contractor's expense if left.
E-7 Hydroseeding Equipment
The above specified components shall be mixed together in the hydroseeding machine
containing at least 2,000 gallons of water to allow for a homogeneous slurry which is
thoroughly mixed and can be applied easily without clogging.
The equipment shall have a built-in agitation system and operating capacity sufficient to
agitate, suspend and homogeneously mix a slurry containing not less than 44 pounds or
organic mulching amendment plus fertilizer, chemical additives and solids for each 100 gallons
of water.
The hydromulching equipment shall meet the minimum requirements of a slurry distribution
line large enough to prevent stoppage and shall be equipped with a set of hydraulic spray
nozzles which will provide a continuous non-fluctuating discharge of at least 25 psi at the end
of the spray nozzle. The slurry tank shall have a minimum capacity of 2,000 gallons.
Equipment used for hydroseeding will be thoroughly cleaned of all seed and other materials
used in preceding hydroseeding processes before any hydroseeding on this project.
E-8 Inspection and Availability
When hydroseeding is completed, the District Engineer will make an inspection to determine
acceptability. Give District Engineer 48 hour notice prior to requested inspection
When inspected landscape work does not comply with these specifications and punch list
items, rejected work shall be corrected and/or replaced and contractor's responsibility
continued until inspected again by the District Engineer and found to be acceptable.
F PAYMENT
All work and material specified in this section shall be paid for on a unit or lump sum basis
as indicated in the bid schedule.
