Desert Knoll Residential Subdivision Project

The Desert Knoll Residential Subdivision Project involves the subdivision of 73.3 acres of predominantly vacant land in Twentynine Palms, California, into 137 residential lots and 4 lettered lots for wastewater treatment, GeoFlow purposes, and retention basins. The development is governed by Tentative Tract Map TTM26-000001 (TTM 20866) and Development Agreement DA26-000001, which establishes a 15-year term consisting of an initial 10-year period with a potential 5-year extension. The project adheres to a Single-Family Residential (RS-3) zoning classification with a maximum density of 3 dwelling units per acre. Infrastructure improvements include the construction of Samarkand Drive and the widening of Desert Knoll Avenue. Comprehensive environmental and technical assessments have been conducted to ensure compliance with CEQA and NEPA guidelines. These include a Phase I Environmental Site Assessment that identified no recognized environmental conditions, as well as biological, archaeological, and paleontological reports confirming the absence of protected species like the Agassiz's desert tortoise and significant cultural resources. Additional studies have addressed noise and vibration, greenhouse gas emissions, air quality, and traffic operations, all of which concluded that impacts are within acceptable limits. A final drainage study and geotechnical report provide the framework for site grading and flood hazard mitigation. The project is managed by the City of Twentynine Palms and 29 Build, LLC, with an anticipated opening year of 2027.
