WINDOW ROCK, Ariz. — Navajo Nation President Dr. Buu Nygren has signed a letter granting consent for the extension of the S-Hill Sand and Gravel Lease operated by the Navajo Engineering and Construction Authority (NECA), supporting continued infrastructure development and economic activity on the Navajo Nation.
The S-Hill Sand and Gravel pit is located within Tse Daa Kaan Chapter in San Juan County, New Mexico. The lease allows for the establishment, operation, and maintenance of a sand and gravel pit, aggregate stockpile, and construction yard that supplies materials used in infrastructure and construction projects across the region.
The original lease was signed by the Navajo Nation on April 6, 2021, and later approved by the Bureau of Indian Affairs on June 29, 2021, for an initial five-year term. Under the lease terms and conditions, NECA may request renewal for additional five-year terms. NECA recently submitted its first request to renew the S-Hill Sand and Gravel Lease for another five-year period.
After review, the Navajo Nation Minerals Department concurred with the extension request, and President Nygren formally provided consent to move the process forward with the Bureau of Indian Affairs for approval.
Operations at the S-Hill site support the availability of locally sourced construction materials needed for roadwork, infrastructure improvements, and development projects across the Navajo Nation. Ensuring a reliable local supply of sand and gravel for infrastructure projects remains a top priority for President Nygren as the Nation continues expanding roads, housing, and community facilities.
The lease also requires NECA to comply with annual royalty payments to the Navajo Nation and follow approved mining and reclamation plans to ensure responsible land management.
This extension continues an important partnership that strengthens economic opportunity while supporting the infrastructure needs of Navajo communities.
