Mulch & Compost

Compost blown in = $45-70/yard

40 pt chipboard $0.79/sheet comes to 10.5 cents / sq ft, double layer with 3” overlap
Erosion Control
Straw wattles 9”x12’ = $16 ea; 9”x 25’ = $32 ea

Straw bale = $10 – 12 covers approx. 400 ft2
Wood stakes 1”x 2”x 2’ = $15 bundle of 50 ($0.22 ea)
Eco-stakes 12” = $110-140 for 500
Metal staple = $40 for 1,000
Black fabric = $.08/sq’
Jute fabric = $48-52 roll covers 900 ft2 (750 w/ overlap)
Wood straw = $11/bale, covers 158 ft2 at 70% cover (>33% slope) or 290 ft2 at 50% cover
Coir fabric 2mx50m roll: covers 1,000 ft2 (940 w/ overlap) -400 is more open weave, 900 is very tight weave (number refers to grams per square meter)
400: $210-265

700: $240-325
900: $258-350
Straw blanket SC150BN - $100, covers 650 ft2
Coir blanket C125BN - $115
Herbicide – Need WA pesticide applicator license (check w/ Project Managers)
Garlon 4 = $250 for 2.5 gallons, mix with oil agridex (cheap) as binding agent.
-Use on tree species like Holly and Cherry Laurel (best during dry conditions)
Aquamaster = $250 for 2.5 gallons
-Use for injecting Knotweed July – early September
Spraying yellow archangel or other dense low plant: 2,000 sq. ft./person-hr, uses approx 10 liters of spray mix/person-hr (1% glyphosate, 2% triclopyr).
Rock
Gravel 5/8 minus = $25/yard, yard = 1.3 tons
Sand = $27/yard, one cu. yd. of sand fills 100 sand bags
1 yard washed gravel (pea gravel) = 1.4 tons
1 yard 2” spall = 1.2 tons
20 One Man rock “grizzly rock” = 1 ton
*Dumpy 3 ton max, F350 & F250 1.2 ton max
Other
Logs from AP Smith = $2.50/ft, maybe $50 delivery fee, depends on customer
Burlap Sacks =
Cardboard = free some various dumpsters around Seattle
Disposal of invasive material – varies depending where you take it (KC transfer, Seattle transfer,
Pacific Topsoil) – budget approx 2-3 cents per square foot or $50 per crew day – but can vary significantly
Planting
1-2 gallon easy soil conditions = 300 – 400
1-2 gallon compact, rocky soil = 170 – 250
5 gallon easy soil conditions = 200 – 250
5 gallon compact, rocky soil = 120 – 150
Bare roots use same formula as potted, maybe slightly better planting rates.
Staking = 2 people 100 – 150/hour
Plugs = 2 people 200 – 300/hour
*These estimates are with little to no plant staging.
Invasive Removal: (no ropes)
Ivy Ground = 4,000 – 8,000 ft2/day
Ivy Tree Survival Rings per day (5’ diameter): bad = 25, normal = 75, easy = 120 – 150

Blackberry brushcutting = 20,000 ft 2 in a really tall, dense area, 40,000 typical (??), up to
100,000 ft 2 in a low, thin area (these numbers are for whole crew working)
Blackberry grubbing = 2,000 (dense monoculture) to 5,000 (fairly sparse cover) sq ft/day
Blackberry cut and dab with herbicide – about 10,000 square feet/ day – moderate density, mixed natives
Erosion control (rolling out and staking, coir or jute) about 3,000 ft2/day
Laying black fabric = 30,000-50,000 ft 2 per day
Mulching = 25 – 50 yards/day, distance dependant
Trail Work:
Trail clearing (brushing out a new trail corridor) approx 50’/person/day (300’ for a crew)
Grubbing organics – approx 20’/person/day (120’ for a crew)
OR consider 100’/day for a crew to do both (should come out about the same)
Structures
Box steps – approx 3-4 per day, probably just 1-2 on the first day
Check steps – approx 20-25 per day
Knotweed injection:
50 to 100,000 sq.ft / day (as in sweeping through patches along rivers –)
12,000 sq. ft/ day in a dense stand BUT be careful – the herbicide is labeled not to exceed 8 qts per acre. Eight quarts is 2,524 stems at 3mL/stem. This comes to just one stem every 17 square feet over an acre (4+ feet o.c.)
2.5 gallons (1 jug ~ about 1 crew day) = 3,150 stems – has to be at least 55,000 sq ft to meet label requirements
Watering:
Typically give about 3 gallons per plant (30 secs flow from a hose), varies depending on soil conditions, rainfall, frequency of watering, budget avail.
To drain the 325 gallon tank takes about 1 hour w. 2 -3 people, depending on terrain and access
(moving hoses around without damaging plants can take up time)
To refill from a garden hose takes about an hour plus travel time, or get a permit for hydrant or to pump water directly from on-site water body.
