PROFESSIONAL ENGINEERING, ENVIRONMENTAL, AND TECHNICAL SERVICES

Indefinite Delivery / Indefinite Quantity (IDIQ) Single Award Task Order Contract (SATOC)

Yakutat, Alaska

RFP Issue Date: July 29, 2026

BACKGROUND

The Yakutat Tlingit Tribe (YTT) is seeking a qualified consulting firm to provide professional civil

engineering, environmental services, engineering services, and technical support services through an

Indefinite Delivery/Indefinite Quantity (IDIQ) Single Award Task Order Contract (SATOC).

YTT administers a diverse portfolio of programs and projects throughout the City and Borough of Yakutat,

including environmental restoration, transportation infrastructure, aquatic organism passage (AOP) culverts,

fisheries, community facilities, environmental resilience, and natural resource management. These efforts are

funded through a combination of Tribal, Federal, State, and grant funding sources and frequently require

specialized professional services.

YTT also administers programs including the Tribal Transportation Program (TTP), the Native American

Lands Environmental Mitigation Program (NALEMP), the Environmental Protection Agency Tribal

Response Program (EPA TRP), fisheries restoration initiatives, and other Environmental Protection Agency

(EPA) and community development efforts.

The Yakutat Tlingit Tribe is deeply committed to keeping the traditional ancestral lands of the Five Chiefs

pristine, thriving, and abundant. Our elders have long called these lands our refrigerator, and have taught us

that we must care for the land in order for the land to care for us. Environmental stewardship is not simply a

regulatory obligation for YTT — it is central to preserving Haa Shaagoon, Our Way of Life, for current and

future generations.

YTT has over twenty years of proven performance under federal Cooperative Agreements with the

Department of Defense through NALEMP, and continuous EPA TRP funding, completing WWII-era

remediation, fuel tank removals, brownfield assessments, and long-term environmental cleanup. Combined

with the Tribal Transportation Program's 113 routes requiring ongoing safety, culvert, bridge, right-of-way,

and infrastructure improvements, YTT's expanding responsibilities demand fast, reliable access to technical,

engineering, and environmental support — especially within Alaska's short work seasons. Establishing this

IDIQ ensures uninterrupted delivery of essential services, strengthens program capacity, and supports YTT's

EPA, fisheries, monitoring, stewardship, and Realty programs by enabling timely, compliant, and coordinated

project execution across Tribal lands.

YTT anticipates continued investment in transportation improvements, aquatic organism passage projects,

watershed restoration, environmental remediation, climate adaptation, bridge development, and transportation

safety.

The selected consultant(s) shall work closely with multiple programs — the Tribal Transportation Program,

the Native American Lands Environmental Mitigation Program, the Environmental Protection Agency Tribal

Response Program, the Environmental Protection Agency, fisheries programs, and environmental monitoring

— to advance strategic planning, funding development, permitting, design, construction, and implementation

of these projects.

The resulting contract shall have a base term of three (3) years, with an option for a two-year extension.

During this period, YTT intends to issue individual task orders for services as project needs arise and funding

becomes available. Task orders will be issued as either lump sum or time and expenses as appropriate to each

scope of work – the selected firm will prepare open book estimates for task order proposals using provided

rate sheets and proposed overhead and profit markup rates as established through this proposal.

A proposal may be corrected, modified, or withdrawn by written request from an authorized agent of the
