EXECUTIVE SUMMARY
A critical drainage system that collects stormwater runoff within the Steele Park Resort and Berryessa Highlands Unit 1 Subdivision catchment basin experienced a structural collapse approximately 200 feet from lake shoreline resulting in surcharged flow over a paved access road during moderate-to-severe atmospheric river storms. Multiple repair alternatives were considered by County staff and a Consultant to restore intermittent flow continuity in the 36 inch diameter culvert. Immediate action is necessary to replace 200 foot segment of the culvert from a sinkhole to the inlet pool in proximity to Steele Park storage facilities and paved access drive to camping areas on the Resort grounds.

ENVIRONMENTAL IMPACT
Consideration and possible adoption of a Categorical Exemption Class 1: It has been determined that this type of project does not have a significant effect on the environment and is exempt from the California Environmental Quality Act. [See Class 1 (“Existing Facilities”) which may be found in the guidelines for the implementation of the California Environmental Quality Act at 14 CCR §15301; see also Napa County’s Local Procedures for Implementing the California Environmental Quality Act, Appendix B.]
BACKGROUND AND DISCUSSION
Please see the attached Memorandum from Chris Silke dated October 27, 2023, for a detailed description of the project, photographs, contractors contacted to perform repairs, and the various repair options considered. The County proceeded with Option No. 2, as indicated in the Memorandum.
Delays associated with the preparation of plans and specifications, advertising and awarding a contract for repairs would be detrimental to the County. Immediate repair is necessary to prevent further damage to the facility with the upcoming rainy season, to prevent further erosion which could wash sediment into Lake Berryessa, and to remove sinkholes that present a potential hazard to the public. The County Executive Officer is authorized to proceed with emergency projects, subject to ratification by the Board, pursuant to Resolution 2015-37 (attached) and Public Contract Code section 22050.
