Planning Commission recommends allowing mixed‑use housing in parts of airport area subject to conditions and fiscal neutrality

The San Luis Obispo Planning Commission recommended Feb. 26 that the City Council introduce an ordinance to amend the Airport Area Specific Plan to allow mixed‑use residential development in parcels zoned service commercial (CS) and manufacturing (M) that lie within Airport Land Use Plan safety Zone 6. The commission voted to forward the amendment, with an added clarification to a conditional‑use finding, after staff, airport land use commission members and commissioners discussed noise, safety and fiscal impacts.

The amendment would not rezone any properties; instead it would allow mixed use where the Airport Land Use Plan and the specific plan’s updated provisions allow it, but only after a conditional use permit (CUP) and specific findings are made. Principal considerations include ensuring projects have demonstrable water and sewer capacity; that projects are fiscally neutral or offset their fiscal impacts; that nearby uses do not create incompatible air, noise or odor conflicts; and that residential portions would be wholly located inside safety Zone 6.

Why it matters: The change would open roughly 236 acres (of about 341 acres of CS and M zoned land within the specific plan area) to the possibility of mixed‑use development, potentially enabling more housing near existing commercial areas while retaining conditions to address airport safety and fiscal impacts.

What staff presented

John Rickenbach, presenting the staff report, said the amendment responds to an updated Airport Land Use Plan adopted by the Airport Land Use Commission in 2021, which removed some density limitations in safety Zone 6 and created an opportunity to reconsider land use rules in the Airport Area Specific Plan. Rickenbach said the city’s 2020 housing element and subsequent zoning updates already allow mixed use by right in CS and M zones elsewhere in the city; this amendment would bring the specific plan area into alignment but retain a CUP requirement to address airport‑area considerations.

Key qualifying findings and limits

Staff showed the draft CUP findings that applicants must meet to obtain approval for mixed‑use projects in CS and M zones within safety Zone 6. Those findings include: demonstrable water and sewer capacity; fiscal neutrality for city services (projects must offset impacts); absence of incompatible nearby emissions/noise/odors/vibration; consistency with airport land use safety and noise restrictions; and adequate emergency response consistent with the city’s safety and climate adaptation policies. The Airport Land Use Commission reviewed the amendment and concluded it is consistent with the ALUP so long as residential uses are wholly in safety Zone 6; staff incorporated that condition into the text.

Fiscal study and concerns

A fiscal analysis in the packet examined two scenarios: (1) full build‑out under current commercial assumptions, which would yield a fiscal surplus on paper but does not match observed market demand; and (2) a likely mixed‑use outcome, which the study found would produce a negative net fiscal impact largely because of an existing tax‑sharing agreement with the county that limits city property tax revenue for the area. Staff said the amendment language requires projects to be fiscally neutral, and the fiscal consultant identified community facilities districts (CFDs), development agreements, or negotiated financing measures as pathways to achieve neutrality on a project‑by‑project or area basis.

Commissioner questions and staff responses

Commissioners asked whether allowing mixed use would permanently remove commercial inventory; staff replied that the zoning would remain CS or M and that mixed use would be an additional option, preserving market flexibility. Commissioners also asked how projects would treat parcels that straddle different ALUP safety zones; staff said mixed‑use residential portions would be restricted to the portions of parcels wholly within safety Zone 6 and that the draft language addresses parcel‑by‑parcel application of density standards.

Several commissioners returned to airport noise and safety concerns. Staff emphasized the amendment’s constraint that residential development must be wholly within safety Zone 6 and reiterated that project‑level review would assess noise, safety, air and emergency‑response issues.

Vote and next steps

The commission voted to forward the amendment and the EIR addendum to City Council with an added staff amendment to a required finding; the commission’s vote was unanimous (Chair Justin Cooley, Vice Chair Houghton, Commissioners Munoz Morris, Jorgensen and Flores). The City Council is scheduled to consider the ordinance on May 6, 2025, according to staff.

Clarifying details

- Area affected: roughly 341 acres of CS and M zoned parcels in the Airport Area Specific Plan; about 236 acres fully within ALUP safety Zone 6. - No zoning changes: the amendment does not rezone parcels; it changes allowed uses within existing CS and M zones subject to a CUP. - Fiscal requirement: proposed amendment includes a requirement that projects be fiscally neutral; consultants identified CFDs or project‑level arrangements as potential strategies. - Environmental review: an addendum to the airport/Margarita final EIR (circa 2003) was prepared; future projects would need project‑level CEQA review as required.

Discussion vs. decision

- Discussion points: compatibility with ALUP safety zones and noise contours; fiscal consequences and methods for achieving fiscal neutrality (CFDs, development agreements, project‑level offsets); whether allowing mixed use would remove commercial inventory; requirement that residential be wholly in safety Zone 6; emergency response standards and consistency with climate adaptation and safety element. - Directions: staff to forward amendment and CEQA addendum to City Council with the added amendment to required finding 5; projects will require CUPs and fiscal‑neutrality demonstrations when applications are submitted. - Decisions: Planning Commission recommended council consideration (motion passed 5‑0).
