You Design the Site — the Grading, the Drainage, the Plan.
Protecting landscape architects and site-planning practices
Landscape architects sell design and judgment, not construction — grading and drainage plans, planting schemes, site layouts, hardscape details, and accessibility compliance that a contractor later builds from. That makes the exposure fundamentally a professional one: when water pools where it shouldn't, a slope fails, a specified plant dies across an entire installation, or a site plan misses an accessibility requirement, the owner looks to the designer whose drawings the work was built from. Because the firm does no actual construction, it avoids the contractor's means-and-methods risk, but it fully owns the liability for the design itself. This is a licensed, judgment-driven practice that needs coverage built around design errors, not a landscaping-contractor or general business policy. It sits alongside architects and engineers in the design professions.
Properly structured coverage protects the firm, its designers, and the owners who build from its plans.
The Landscape Architect's Signature Exposures
The signature exposure is professional errors and omissions in the design. The recurring claims are drainage and grading plans that cause flooding, erosion, or standing water, slopes and retaining schemes that fail, plant and material specifications that die off or prove wrong for the site, hardscape details that don't perform, and site plans that miss an accessibility or code requirement. Because the firm's drawings are relied on by owners and contractors, a design error can drive remediation and re-construction costs far larger than the design fee. Contracts add to it: owners and prime designers routinely require professional liability at set limits, and broad indemnities can enlarge a negligence claim. The design, and the reliance others place on it, are the exposure.
Key Risks in Landscape Architecture
Landscape architecture practices face exposure related to:
A grading or drainage design that causes flooding, erosion, or standing water
A slope, retaining, or site scheme that fails after it is built
Plant or material specifications that fail across an installation
A site plan that misses an accessibility or code requirement
Reliance by owners and contractors that enlarges a design error into re-construction cost
Contractual indemnities and insurance requirements from owners and prime firms
Breach of project files, drawings, and client data
The drainage-or-grading design claim and the reliance that magnifies it are what most define the practice.
Core Coverages for Landscape Architects
A properly built landscape architecture program typically includes:
Professional Liability / E&O — Covers defense and damages when a design, specification, or plan is alleged negligent and causes a loss — the core policy, written claims-made.
General Liability — Protects against third-party bodily injury and property damage, commonly bundled into a business-owner's policy.
Cyber & Data Breach — Protects project files, drawings, and client data from breach or loss.
Valuable Papers & Documents — Reimburses the cost to recreate drawings, plans, and records after a covered loss.
Commercial Property / BOP — Covers the office, plotters, computers, and business income.
Workers' Compensation — Provides legally required coverage for staff.
Employment Practices Liability — Defends employee discrimination, harassment, and wrongful-termination claims.
Umbrella / Excess Liability — Adds higher limits above the primary program.
What's Commonly Overlooked
Landscape architecture programs are most often weakened by:
Assuming a landscaping-contractor or general policy covers a design error — it does not
Professional liability limits below what owner and prime-firm contracts require
A retroactive date or missing tail that leaves earlier projects uncovered
No coverage to recreate lost drawings and project files
Broad contractual indemnities accepted without reviewing them against the policy
The gap that hurts most is carrying a contractor-style policy when the real exposure is a design claim only E&O will answer.
Real-World Claim Examples
A drainage plan causes a finished site to flood and the owner demands regrading
A specified slope erodes or fails after construction
An entire planting scheme fails because of a specification error
A built site is found noncompliant with an accessibility requirement in the plans
An owner sues over a design the contractor built exactly as drawn
A single drainage or grading claim can cost far more than the design fee, so limits and claims-made terms matter.
Regulatory & Contract Context
Landscape architecture is a licensed profession in most states, typically requiring the Landscape Architect Registration Examination and ongoing registration, and the firm's work is governed by professional standards of care. In practice, contracts drive the insurance: owners, developers, and prime design firms commonly require professional liability at set limits, proof by certificate of insurance before an engagement, and additional-insured status for the general liability. Where the firm's plans touch public works or accessibility, code and ADA requirements attach to the design obligation.
Why Proper Placement Matters
Underwriters weigh revenue, the project types and sizes, whether the firm touches public infrastructure or only residential and commercial sites, the use of subcontracted engineering, contract and scope quality, and prior claims. Professional liability is claims-made, so the retroactive date and tail are decisive when designers move between firms or the practice is sold. Matching limits to owner and prime-firm contract requirements, and placing the program with design-professional markets, is what keeps the coverage sound.
Our Approach
At Cory Washington & Co., we insure landscape architects around the design exposure that defines the practice — grading, drainage, and site plans others build from. We structure errors-and-omissions to meet your owner and prime-firm contract requirements, add coverage to recreate lost drawings, and coordinate general liability, property, and umbrella into one program placed with design-professional markets. We also insure related design practices, including architects and engineers, draftsmen, interior designers, and landscaping contractors on the construction side.
You design the site others build — we build coverage that defends the plan.

Premiums vary from business to business.
