BACKGROUND:
On, July 9, 2019, your Board adopted Resolution Nos. 076792 and 076793, which authorized the purchase and sale agreements for the acquisition of 331 and 340 Scenic Drive, respectively; and authorized the County Manager, or his designee, to execute any and all notices, exemptions, and escrow instructions, as well as the Deed Restrictions attached to the Grant Deeds, and the Certificates of Acceptance, all as required to facilitate the purposes of the Purchase and Sale Agreements.
DISCUSSION:
The two residences to be demolished and materials disposed of offsite are located at 331 and 340 Scenic Drive, in La Honda. The La Honda Area, like much of the County, suffered record rainfall during the 2016-2017 winter. On January 11 and 12, 2017, the heavy rainfall caused an integral ground failure in the area where these residences are located. The homes on the subject properties sustained substantial structural damages and the properties were subsequently red-tagged by the County and deemed uninhabitable.
The Hazard Mitigation Grant Program (HMGP) is a federal program offered by the Federal Emergency Management Agency (FEMA), administered through the states, as applicants. HMGP provides funding for eligible activities that reduce community vulnerability to disasters and their effects, promote individual and community safety and resilience, and promote community vitality after an incident. The County, as a sub-applicant, applied for and was approved HMGP funding through the California Office of Emergency Services.
The County has utilized a portion of the grant funding to acquire these two properties. The property located at 331 Scenic Drive consists of an approximately 24,200-square foot parcel, with a 2,854-square foot, six-bedroom, three-bathroom residential structure. The property at 340 Scenic Drive consists of an approximately 5,733-square foot parcel with a 720-square foot, one-bedroom, one-bathroom residential structure.
The existing structures will be demolished, and the property will be converted to open space in accordance with the HMGP funding requirements. The demolition will have the following mitigation benefits: 1) removing the structures and converting the two properties to open space eliminates the public safety threat to human life that exists while the structures remain in place; 2) removing the weight of the existing structures on the earthen slope where the structures are situated; and 3) allowing for implementation of grading and erosion control measures as part of the Project. After this Project is completed, a separate FEMA funded project will follow to restore the portion of Scenic Drive that was damaged as a result of the integral ground failure at this location.
Although the structures on the properties will be demolished and removed, a Phase 1 Environmental Site Assessment was commissioned for each of the two properties, which determined that no conditions were discovered that require further analysis or review.
FEMA completed an environmental review for the acquisition of the properties and demolition of the structures pursuant to the National Environmental Policy Act requirements and determined this work to be categorically excluded pursuant to Categorical Exclusions N3 and N12. This work is exempt from the California Environmental Quality Act pursuant to Statutory Exemption 15269, “Emergency Projects.”
County Counsel has reviewed and approved the resolution as to form.
FISCAL IMPACT:
The estimated construction cost for this Project is $511,000, and 75 percent of these costs will be reimbursed by FEMA HMGP funding grant. The remaining costs will be funded by General Fund.
