Harbor Coastal Commission Discusses Floodplain Impacts for 1025 Rushmore Property Amidst Stormwater Regulation Review

The Harbor Coastal Commission reviewed and approved minutes from the November 19th, 2025 meeting [cite: 21-28]. The commission then engaged in a discussion regarding the 1025 Rushmore property, specifically addressing concerns about fill and its impact on flood elevations and surrounding properties [cite: 29-34, 46-49]. Due to a moratorium on approvals related to stormwater regulation changes, a final vote could not be taken, but the discussion aimed to address all concerns thoroughly [cite: 31-33, 60-64]. The applicant, Orient Beach Club, represented by Andrew Spatz, presented updated information and analysis from Race Coastal Engineering, addressing previous comments and concerns regarding fill volume, flood storage capacity, base flood elevation, wave action, wave run-up, and water velocity [cite: 36, 69-72, 78-89, 98-101]. The engineering analysis concluded that the proposed fill would not appreciably affect flood elevations or create adverse impacts on the site or adjacent properties [cite: 78-81, 87, 138, 161]. Discussions also touched upon the village's stormwater regulations and potential changes, with assurance that future proposals would need to comply with updated standards [cite: 345-350]. The commission considered the site-specific analysis and the potential for increased flooding on neighboring properties, which the applicant's expert team stated would not occur [cite: 182-183, 218-223, 285-288]. Concerns about compensatory fill were also discussed, with the applicant presenting reasons why it might not be practicable for this specific site [cite: 294-296]. The meeting also included a discussion on general stormwater management, which was noted as being outside the scope of the current discussion but relevant to future compliance [cite: 341-348].
