KTA Associates

What KTA Associates does

KTA Associates, Inc. is a Seattle-headquartered environmental engineering and consulting firm founded in 2001 by Ken Taylor. The company delivers four integrated service lines: compliance and planning, risk management (including Phase I and Phase II Environmental Site Assessments under ASTM, state, provincial, and federal standards), site restoration, and litigation support. Its client base spans the U.S. Department of Defense (Army, Navy, Air Force installations such as Fort Lewis and Vandenberg AFB), multinational renewable energy developers in wind, solar, and battery storage, large financial institutions and insurers supporting property transactions, the largest parcel shipping company in the world, a national wholesale warehouse corporation, three large Washington power plants, and large hospitals in Oregon and Washington. Project work spans 45 of 50 U.S. states, one U.S. territory, and five Canadian provinces, executed through a combination of in-house senior staff and a network of nationally recognized partner environmental engineering firms, with offices in Seattle, San Diego, Denver, Phoenix, and Austin.

The firm's technical differentiator is its use of probabilistic software tools to translate environmental contamination risk into financial terms, allowing lenders, insurers, developers, and attorneys to evaluate environmental liability in dollar-denominated context. KTA has experience supporting transactions ranging from $50,000 to over $6 billion in value, and site restoration engagements ranging from $10,000 to over $120 million in cost, with Phase I/II ESAs in renewable energy cumulatively exceeding 400 wind farm assessments across 41 states and 2 Canadian provinces over 20 years, 75+ solar farm assessments across 18 states over 10 years, and 15+ battery storage assessments within 2 years.

KTA operates as a privately held, project-based professional services firm with multi-year contracts and 100% of new business generated through client referrals. The company is founder/management-owned with no disclosed private equity, venture capital, or parent entity, and its 20-year-plus relationships with anchor enterprise clients underscore the durability of its referral-driven commercial model. Pricing is custom-quoted based on project scope, and the firm emphasizes senior expert delivery, staff retention, and work-life balance as core cultural elements.
