Sonata Property

Sonata Property Open Space Preserve (Preserve) consists of 2.89 acres in the City of Carlsbad, southeast of the intersection of Calle Timiteo and Camino De Los Coches, across the street from Stagecoach Community Park. San Diego Habitat Conservancy (SDHC) expects to commence active management of the Preserve in 2018 after a 5-year enhancement program is completed. As grantee to the conservation easement for this property, in early 2016 SDHC began conducting easement compliance monitoring visits 3 times per year.

History: This open space preserve was required to be set aside as mitigation for construction of the La Costa Town Center Residential Office and Commercial Development Project which created a community shopping center, office space, and single family residential housing. The project impacted approximately 0.41 acre of U.S. Army Corps of Engineers jurisdiction, of which 0.08 acre consisted of jurisdictional wetlands. Of the 2.98 acres, 1.41 acres were preserved while the remaining 1.57 acres underwent enhancement beginning in 2012.

Habitat: The Preserve consists of 0.99 acre of southern willow scrub, 0.78 acre of valley grassland, 0.73 acre of alkali marsh, 0.43 acre of brodiaea habitat, and 0.05 acre of freshwater marsh.

Management Duties: San Diego Habitat Conservancy will monitor the Preserve three times a year to observe and document substantial changes in the habitat composition and the need for remedial measures. Trash and non-native, invasive plant species are removed as necessary.

Species of Special Interest: southwestern spiny rush, thread-leaved brodiaea, Orcutt’s brodiaea.
