Identification of Issues
Issues
Strategy
Consideration
Action Items
15
Water
Issues
Water withdrawal permit limitations
Peak water usage associated with tourism
Recommended Strategies
Installation of a Cretaceous Well and RO Treatment Facility
Water conservation education targeting tourists & development community
Alternative water sources including: gray water, rainwater capture, shallow wells, and reuse
16
Wastewater
Issues
Peak wastewater discharge associated with tourist season.
Capacity of WPCP infrastructure to accommodate more flow
Potential water quality issues from discharge/future permit standards
Potential Strategies
Upgrade WPCP to accommodate more flow and to treat to a higher standard.
17
Stormwater/Flooding
Issues
Nuisance flooding associated with king high tide and rain events.
Sea level rise is exacerbating flooding
Water quality issues that result from flooding
Recommended Strategies
Implement priority recommended improvements from the Sea Level Rise Study.
Advocate for elevation of Highway 80.
Limit new impervious surfaces.
Limit new construction in areas subject to flooding.
18
Solid Waste
Issues
Litter on beach
Municipal solid waste (MSW) disposal trends are still increasing despite the availability of recycling.
Recycling receptacles are often contaminated by MSW.
Yard waste is being left on the road/curb and not being picked up
Recommended Strategies
Reduction of waste generation on island
Alternatives for solid waste disposal in landfills off island
Waste reduction education & litter education for tourists
Enforcement of litter ordinance
19
Energy Consumption
Issues
City operations result in energy use, which contributes to greenhouse gas emissions.
The billing system of Georgia Power makes tracking and analyzing energy usage difficult.
Recommended Strategies
Reduce energy usage within City facilities.
Promote energy efficiency through education and incentives.
20
Traffic/Parking
Issues
Peak traffic flow issues related to day-trippers and events creates.
Traffic resulting from accidents and flooding on Hwy 80 cuts off access to the island resulting in economic losses and emergency situations.
Lack of parking creates congestion and illegal parking problems during peak tourism season.
Potential Strategies
Improve Hwy 80 to provide passable shoulders and an elevated road bed.
Provide additional parking opportunities.
Provide multi-modal opportunities for transportation to and within Tybee Island.
Notify people about traffic congestion and parking issues before they get on-island.
21
Short Term Rentals
Issues
1. Peak water and wastewater usage on the island is driven largely by short-term rentals.
Strategies
Identify appropriate way to regulate the short-term rental industry.
22
Zoning
Issues
The R-2 Zoning District will allow for additional development through subdivision and redevelopment of existing lots.
The area subject to flooding during King tides and rain events, is in the R-2 District.
Strategies
Regulate future development and redevelopment in the R-2 District, especially areas that are subject to flooding.
23
City Resources
Issues
The City does not currently have the funding necessary to implement needed capital improvements.
The City needs staff resources to focus on issues identified in this plan.
City needs reserves for disaster preparedness and infrastructure improvements.
Strategies
Identify other funding sources for improvements
Identify or hire staff to focus on Carrying Capacity Issues
24
