Keller discussed the concept of managed retreat as an option for dealing with sea level rise but noted the community’s preference to remain and fortify against the encroaching waters rather than consider strategic relocation. The conversation highlighted the potential use of stormwater pumps and the importance of private property protection in the city’s no-fill environment. Questions arose regarding the timeline for seeing tangible results and the difficulties of promoting a vision with long-term benefits. The agency acknowledged the need for constant nurturing and adaptation of the program to meet future challenges.

The meeting also focused on revisions to the utility section of the local development regulations. The proposed changes would require developers to demonstrate reductions in nutrient loading in stormwater discharge, with specific exemptions debated for single-family developments. The importance of clear communication of these regulations to both staff and the community was underscored.

There was debate concerning the impact of these regulations on development projects, particularly on single-family homes, and larger ventures. Concerns were raised about the reduction of impervious surface ratios and their implementation, particularly on single-family homes undergoing renovations or new construction. The agency clarified that while less impervious surface leads to reduced nutrient loading, any changes to ratios would necessitate amendments to the comprehensive plan and local development regulations.

In the context of stormwater permits, the need to account for sea level rise and the shift to performance-based treatment was discussed. The agency clarified design requirements for stormwater systems, including the support of piped outfalls and the framework for regional treatment facilities. The evaluation of treatment methods, such as low impact development and green infrastructure, was addressed, along with the importance of proper construction and maintenance requirements.

The discussion extended to the topic of cumulative substantial improvements (CSI) and the evaluation of property improvements’ impact on the city’s flood insurance rating. There was debate about the implications of changing the CSI time frame on residents, with concerns about the balance between long-term resiliency goals and the practical repercussions for property owners. The potential of lowering the city’s flood insurance premiums through the Community Rating System (CRS) was also discussed, as was the verification process and the impact of the Coastal Stormwater Program on property values.

The meeting touched upon the redevelopment of downtown Treasure Island, aiming for a unified design standard, and the potential for a new restaurant to anchor future development. Additionally, the proposed ordinance allowing for the elevation of homes on Treasure Island was debated, focusing on the impact on private homeowners, technical aspects of home elevation, and cost considerations.
