Neighborhood Benefits •Elevating the roadway to 3.7 NAVD to prevent street flooding during high tides and sea level rise protection. •New water and sanitary infrastructure for improved service. •New crosswalk pavers at various intersections. •New protected bicycle lanes. •New landscaping throughout the neighborhood. •New storm water management system for over 147 Acres in the neighborhood to prepare for 10-year rain events. Harmonization Guiding Principles •Our philosophy is to provide public safety improvements to the publicly owned rights-of-way. •Right-of-Way agreements are intended to remain in existence. If you have a developer agreement, an encroachment permit, etc. those terms should remain for specialty fixtures, pavers, or landscaping. •Cost of adapting will be handled as follows: •Public Funds must be used for public improvements. •Private funds are used for private property improvements. 10 Provides access and creates a smooth transition from the existing property to the new, raised elevation of the street. Harmonization is needed so that vehicles and people can safely enter and exit driveways and walkways during and after construction. Harmonization Definition Policy Overview •Comprehensive policy that is inclusive of all property types. •If water ponds excessively, you’ll get a drain. •The clauses in the policy are there to ensure we maximize the amount of fresh water being absorbed in green spaces. •There will not be any fees for private property drainage connecting into public system. •In the future, once a property is redeveloped at a higher elevation, the connection is no longer needed. 11 12 Base: D/B Team Recommended Highly Preferred Recommendation Not Recommended Engineering & Construction Perspective: Option Location Underground Component Location Generator Location FPL Vault Location Control Pane(s)l Location 10-Year Storm Piping Emergency Gravity Bypass Cost Impact Cost above Base option 1 Construction Time Impact (Days)Recommendation 1 Lincoln Court & Bay Road;
