California CSLB Hydroseeding Contractor D-14 / C-61 Attorney Fee Petition Mechanics: Tyler Odyssey Civil Complaint Date as Primary Welch Anchor, CSLB License Check (D-14 / C-61) as Secondary Anchor (THE ONLY D-14 Hydroseeding Page in This Series — DISTINCT FROM D-7 Excavating, Grading, Trenching — ONLY Page With IECA TC-6 Hydraulic Mulch Technical Guidance Advisory [THE ONLY PAGE in the Fee-Petition-Mechanics Series With an IECA TC-6 Advisory — PURE KETCHUM] and ASTM D6459 Standard Test Method for RECP Performance Advisory; RWQCB Construction General Permit SWPPP Compliance as Second Institutional Anchor; Slope Revegetation Failure Downslope Property Damage / SWPPP Violation Stop Work Order / Wrong Seed Mix Grading Permit Open Real Estate Closing Delay Three-Track Harm; Bus. & Prof. Code § 7031(b) Disgorgement), CLRA § 1780 Mandatory Attorney Fees

Statutory Framework: Bus. & Prof. Code § 7028, D-14 / C-61 Hydroseeding, IECA TC-6 Advisory, ASTM D6459 Advisory, RWQCB SWPPP Advisory, § 7031(b) Disgorgement, and CLRA § 1780 Mandatory Attorney Fees

California Business and Professions Code § 7028 prohibits unlicensed contracting. The CSLB D-14 (Hydroseeding) limited specialty designation under C-61 authorizes: spray application of wood fiber hydraulic mulch on residential and light commercial cut/fill slopes; application of grass seed mix, wildflower seed, or erosion control seed combined with hydraulic mulch in the same slurry; application of starter fertilizer (nitrogen-phosphorus-potassium) combined in the hydraulic mulch slurry; application of organic or synthetic tackifier (guar, psyllium, polyacrylamide) at required concentration to bond mulch fibers to soil surface; application of bonded fiber matrix (BFM) or mechanically bonded fiber matrix (MBFM) on slopes steeper than 2H:1V where standard hydraulic mulch is insufficient; and post-application germination monitoring with re-application as required by grading permit conditions. D-14 does not cover: earthwork, grading, or soil movement (requires D-7 or C-12); installation of jute mesh, straw wattles, or silt fence erosion control devices without hydroseeding (requires D-7 or general contractor); planting of containerized plants, shrubs, or trees (requires C-27 Landscaping); or installation of drip or overhead irrigation systems on revegetated slopes (requires C-27 Landscaping). D-14 is distinct from D-7 because D-7 covers the earthwork that creates the slope, while D-14 covers only the erosion control revegetation of the completed slope.

IECA TC-6 Hydraulic Mulch Application Technical Guidance (published by the International Erosion Control Association) is a private trade association technical guidance publication — NOT a California statute, NOT California administrative code, NOT a federal regulation creating mandatory civil attorney fees. IECA TC-6 specifies: minimum wood fiber mulch application weight — 1,500 lbs/acre for slopes ≤ 3H:1V (horizontal to vertical); 2,000 lbs/acre for slopes between 2H:1V and 3H:1V; bonded fiber matrix (BFM) required for slopes steeper than 2H:1V (50% gradient); bonded fiber matrix application minimum 2,500 lbs/acre; tackifier application minimum concentration 0.25% by weight of wood fiber in slurry; hydraulic application equipment must be calibrated in gallons of slurry per acre prior to each application day; germination rate verification required at 30 days post-application; contractor must perform re-application or install erosion control blanket if germination rate is below 60% at day 45; seed mix must include minimum 30% perennial grass species for permanent erosion control on slopes where grading permit requires permanent cover; annual ryegrass alone is not acceptable for slopes requiring permanent vegetation under RWQCB Construction General Permit conditions. PURE KETCHUM: IECA TC-6 is a private International Erosion Control Association technical guidance publication — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism for persons harmed by unlicensed California D-14/C-61 hydroseeding contractors.

ASTM D6459 Standard Test Method for Determination of Rolled Erosion Control Product (RECP) Performance in Protecting Hill Slopes from Rainfall-Induced Erosion (published by ASTM International) is a private technical standard — NOT a California statute, NOT California administrative code, NOT a federal regulation. ASTM D6459 specifies: standardized rainfall simulation protocol for comparing RECP (jute blanket, straw mat, bonded fiber matrix, coir mat) soil loss performance against a bare soil control plot; minimum acceptable percent reduction in soil loss versus control plot for each RECP category; slope gradient and slope length test specifications (1.5H:1V, 2H:1V, 3H:1V test slopes); wet application method for bonded fiber matrix products; dry application method for rolled blanket products; reporting requirements for mean soil loss, percent cover, and shear stress resistance; third-party testing laboratory certification requirement for RECP manufacturers claiming D6459 performance levels. PURE KETCHUM: ASTM D6459 is a private ASTM International standard — it creates no private civil right of action and no mandatory attorney fee-shifting mechanism; violations generating slope failure and downstream property damage are recoverable as CLRA actual damages.

Primary Welch Anchor: Tyler Odyssey Civil Complaint Filing Date

The Tyler Odyssey civil complaint filing date is the primary Welch temporal anchor for D-14 hydroseeding matters. The attorney files after confirming CSLB C-61/D-14 license status, reviewing RWQCB Construction General Permit SWPPP records, retaining a CPESC erosion control specialist to document slope mulch weight and germination compliance, inspecting downslope property damage, and serving the CLRA § 1782 demand. The CSLB D-14/C-61 License Check date is the secondary Welch anchor. Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).

Secondary Anchor: CSLB License Check (D-14 / C-61 Hydroseeding) — THE ONLY D-14 Specialty Anchor in the Fee-Petition-Mechanics Series

The CSLB License Check must confirm the C-61/D-14 Hydroseeding limited specialty designation — distinct from D-7 (Excavating, Grading, Trenching, which covers earthwork), D-49 (Tree Service, which covers existing tree care), and C-27 (Landscaping, which covers full landscape scope). Three scenarios generate § 7028 liability: (a) no CSLB license at all; (b) expired, suspended, or revoked C-61/D-14 license; (c) a landscaper or grading contractor who performs hydroseeding as a standalone service without holding the D-14 limited specialty. This page is THE ONLY D-14 Hydroseeding specialty anchor in the fee-petition-mechanics series.

Billing Gap 1 — CSLB D-14/C-61 License Check, RWQCB SWPPP Review, IECA TC-6 Mulch Weight and Germination Documentation, ASTM D6459 BFM Product Review, and § 1782 Demand (5.25 hrs/yr = $1,575–$2,625)

The first billing gap covers pre-complaint advisory for D-14 hydroseeding matters.

• Searching CSLB License Check for C-61/D-14 designation and establishing the secondary Welch anchor: confirming D-14 limited specialty presence or absence; evaluating D-7 distinction (earthwork vs. erosion control revegetation); confirming license status, bond, and workers compensation insurance.
• Reviewing RWQCB Construction General Permit Notice of Intent and SWPPP records — second institutional anchor: obtaining the CGP Notice of Intent to confirm whether the project required SWPPP-based erosion control BMPs; reviewing SWPPP to identify specified hydroseeding application rates and seed mix requirements; confirming whether SWPPP BMP log was maintained as required by CGP Order 2022-0057-DWQ.
• Retaining CPESC specialist for IECA TC-6 mulch weight and germination documentation: CPESC or licensed civil engineer documents actual mulch coverage weight per acre using ASTM measurement method; assesses slope gradient against IECA TC-6 BFM threshold (2:1 cutoff); documents germination rate per square meter and compares to TC-6 60% minimum threshold at day 45.
• Reviewing ASTM D6459 BFM product performance data: obtains product data sheets for hydraulic mulch materials used; confirms whether BFM products were D6459-certified; compares certified soil loss reduction data against TC-6 minimum requirements for the slope gradient.
• Serving CLRA § 1782 demand incorporating IECA TC-6 and ASTM D6459 advisory analysis: demand specifies D-14 unlicensed contracting, identifies three harm tracks, demands disgorgement under § 7031(b), and specifies CLRA § 1780 mandatory attorney fees.

Billing Gap 2 — Active Litigation: CPESC Erosion Expert, Geotechnical Engineer, RWQCB Enforcement Response, and Three-Track Damage Quantification (4.00 hrs/yr = $1,200–$2,000)

The second billing gap covers expert coordination across the three D-14 harm tracks.

• Retaining CPESC erosion control specialist and geotechnical engineer for Track 1 slope failure: expert documents volume of soil displaced (survey stakes and cross-section calculation), confirms IECA TC-6 deficiency (600 lbs/acre applied vs. 2,000 lbs/acre required), models expected erosion under 0.8-inch rain event for properly BFM-treated slope as a counterfactual; quantifies re-grading, re-revegetation, and neighbor property restoration costs.
• RWQCB enforcement response and penalty calculation for Track 2 SWPPP violation: attorney reviews RWQCB Notice of Violation and stop work order; coordinates with environmental compliance specialist to document SWPPP log deficiencies; calculates Water Code § 13385 civil liability exposure for the property owner; quantifies construction delay damages from stop work order including contractor idle equipment costs and subcontractor delay claims.
• Grading permit closure analysis for Track 3 real estate delay: attorney obtains county grading permit and vegetation confirmation inspection requirement; documents annual ryegrass seed mix specification vs. perennial grass requirement; retains licensed hydroseeding contractor to provide written bid for perennial grass re-seeding and wait time until county confirmation inspection; calculates real estate carrying cost damages through 8-month delay period including mortgage interest, insurance, property tax, and temporary housing.
• Settlement valuation incorporating all three harm tracks and CLRA § 1780 mandatory attorney fees: D-14 three-track settlement demand integrates downslope property damage, RWQCB penalty and delay costs, and real estate transaction delay damages with CLRA mandatory attorney fees.

Billing Gap 3 — CLRA § 1780 Fee Petition, Pure Ketchum Multiplier, Lodestar Documentation, and Missouri v. Jenkins Fees-on-Fees (4.00 hrs/yr = $1,200–$2,000)

The third billing gap covers fee recovery preparation across all three D-14 harm tracks.

• Documenting the CLRA § 1780 lodestar from the CSLB D-14/C-61 License Check date: RWQCB CGP Notice of Intent and SWPPP records retrieval; IECA TC-6 mulch weight measurement data; ASTM D6459 product data sheet analysis; CPESC slope failure expert opinion; geotechnical survey of displaced soil volume; licensed contractor bid for re-grading and re-revegetation; county grading permit vegetation confirmation inspection records; real estate carrying cost calculation — all fee-petition-eligible.
• Briefing the pure Ketchum multiplier: novelty/difficulty — IECA TC-6 BFM threshold analysis (2H:1V slope gradient determination; field measurement of actual mulch weight per acre; germination rate quantification methodology; ASTM D6459 certified product comparison); RWQCB CGP SWPPP log deficiency analysis (documentation requirements vs. actual records; Water Code § 13385 penalty exposure modeling); annual ryegrass die-off causation analysis (phenology of cool-season annuals in California Mediterranean climate; permanent cover requirement timing relative to grading permit conditions); Ketchum v. Moses 24 Cal.4th 1122 (2001); PLCM Group Inc. v. Drexler 22 Cal.4th 1084 (2000).
• Missouri v. Jenkins fees-on-fees for the fee petition: Missouri v. Jenkins 491 U.S. 274 (1989); Hensley v. Eckerhart 461 U.S. 424 (1983).
