Platting board approves Wilmington Hill subdivision despite wetlands and emergency-access concerns

The Matanuska-Susitna Borough Platting Board approved the Wilmington Hill preliminary plat, a proposal to subdivide roughly 80 acres into 76 lots, after extended public testimony and technical exchanges about wetlands, septic feasibility, emergency access and the applicability of state fire code.

Cayman Reynolds, platting staff, summarized a geotechnical report showing 22 test holes and noted three holes encountered water at 8.5 to 10.5 feet; staff recommended approval with seven findings and eight conditions. Fred Wagner, planning officer, told the board the packet language for condition 4 was updated to require road construction to meet Mat-Su Borough standards in the 2022 subdivision construction manual rather than a previously stated "pioneer" standard.

Multiple nearby residents urged the board to delay approval or require additional access. "I have a great concern for the wetlands around...I think that that is something that should be looked at deeply," said Patricia O'Neil, a nearby resident. Thomas O'Neil, another adjacent property owner, raised runoff and service concerns, saying the area floods and that there is only one road for evacuation and emergency response.

Beth Hastings, a resident who cited state statutes and borough code during her comment, told the board the proposal exceeded the borough's threshold and argued that a secondary fire apparatus access is required for more than 30 units. "This subdivision is not compliant with law," Hastings said, urging the board to require a second access to meet fire and lending standards.

Planning staff and the petitioner disputed that the international fire code applies to subdivision approvals. "The fire code is not something that is applicable to subdivisions," said Fred Wagner, planning officer, explaining the borough's interpretation that the international fire code regulates buildings and structures rather than the subdivision of land. Staff said borough thresholds require 3,000 trips per day before a second access is mandated — a level far above traffic expected from this subdivision.

The petitioner, Maxwell Sumner, and representatives said they obtained prior permits and a jurisdictional determination that the parcel and access road are nonjurisdictional. "They determined that it was not jurisdictional," the petitioner said, describing a third-party determination used after the Corps changed its process.

Petitioners and engineers said septic tests and drainage monitoring were performed to borough standards, that drainage will be held on-site, and that test-hole monitoring will continue during the growing season. Developers also noted the plat shows stub roads intended for future interconnectivity when adjacent parcels develop.

After discussion including recorded objections from two board members, the board approved the preliminary plat contingent on the staff recommendations. Planning staff said preconstruction review and permits will address detailed drainage and construction standards.

The board will consider follow-up items at its next meeting; staff noted no further immediate action was required beyond conditions and standard permitting steps.
