Hurley Ranch Tentative Tract Map (SUB2013-0009) Tract 3053

The San Luis Obispo County project involves Major Grading Permit GRAD2025-00071 for the construction of an 841 square-foot accessory dwelling unit, an 842 square-foot attached garage, and a 189 square-foot entrance porch at 509 Hurley Ranch Road. Located within the Residential Rural land use category in the San Luis Bay Inland Sub Area, the project will disturb approximately 9,700 square feet of a 4.83-acre parcel and include 300 cubic yards of cut and fill. The project is consistent with a previous Mitigated Negative Declaration, and a Notice of Exemption has been issued confirming no new environmental impacts are anticipated. The broader scope includes the Hurley Ranch Tentative Tract Map (SUB2013-0009) for 13 proposed lots on Erhart Road in Arroyo Grande. Key deliverables include the widening of Erhart and Vetter Roads to A-1 rural road standards, the construction of Hurley Ranch Road, and intersection improvements at Erhart Road and Old Oak Park Road. Because Hurley Ranch Road does not meet criteria for the County maintained road system, the developer must establish a private road maintenance mechanism, such as a Property Owners Association. All improvement plans must be prepared by a Registered Civil Engineer and adhere to County Public Improvement Standards and the 1997 Uniform Building Code. Administrative requirements include the submission of a cash deposit and an executed Checking and Inspection agreement to cover Public Works review and inspection costs. The applicant must post a performance bond equal to the cost estimate before initiating site grading. Environmental compliance requires annual monitoring reports for at least three years and strict adherence to erosion control revegetation between October 15 and April 15. Additionally, the project must comply with CAL FIRE recommendations and Fire Safety Standards LUO Sec. 22.05.086. Specific protocols are in place for the discovery of archaeological resources or human remains, requiring immediate cessation of work and notification of the County Coroner and relevant departments.
