About this home
DISCREET INSTITUTIONAL OPPORTUNITY | 89.88 CONTIGUOUS ACRES | SINGLE LEGAL LOT Positioned at the strategic intersection of ecological asset preservation and multi-use land holding, this unified 89.88-acre contiguous tract represents one of the final legacy footprints in the Bonsall’s San Luis Rey River corridor. Comprising three parcels legally bound as one single lot, the property’s unique strength lies in its naturally bifurcated biological and topography profiles. THE ECOLOGICAL FOOTPRINT: Approximately 69.26 acres feature pristine, high-density native flora, including Diegan Coastal Sage Scrub and a prominent Southern Willow Scrub riparian corridor intersecting the acreage. This native landscape serves as an exceptional private nature buffer, insulating the topography from future regional fragmentation. Positioned ahead of the upcoming North County Multiple Species Conservation Program (MSCP) framework, this acreage presents significant long-term potential for high-value conservation easements, regional habitat mitigation offsets, or permanent stewardship. THE UTILITY CORE: Approximately 20.26 acres of flatter, low-constraint topography—predominantly classified as non-native grassland, disturbed habitat, and existing agricultural pockets—provide an immediate, friction-free envelope for a grand private compound, secure ingress/egress, or sovereign holding utility without triggering extensive environmental mitigation exposure. This is a data-driven land holding tailored explicitly for the forward-thinking legacy investor, conservation trust, or sovereign entity seeking absolute privacy, environmental equity, and watershed security. Complete biological mapping, Holland Code habitat classifications, and certified parcel surveys are available upon request. The offering price reflects a repositioning of assets from conventional rural or residential land to a strategic land holding aligned with the emerging MSCP-driven demand dynamics.
The RR Use Regulations are intended to create and enhance residential areas where agricultural use compatible with a dominant, permanent residential use is desired. Typically, the RR Use Regulations would be applied to rural or semi-rural areas where urban levels of service are not available and where large lots are desired. Various applications of the RR Use Regulations with appropriate development designators can create buffers between residential and agricultural uses, family or small farm areas, or large lot rural residential developments.
