9 Golden Gate Canal Diversions 200 mgd Henderson Creek

10 Five Years From Now: THE RESULTS One third of Golden Gate Canal water diverted to Henderson Creek. City s ASR well reduces flows another 10%.

11 Ten Years From Now: THE CRITICAL POINT Marco Island ASR takes another 10% of the flow. Water reaching bay reduced to 50% of current tlevels. l

38 Five Years From Now: THE RESULTS Floating islands and aerators are located in 10 of the City s lakes. Outreach Coordinator working with residents To build rain gardens. To plant shorelines Water quality of the bay is improving and Water quality of the bay is improving and healthy habitat is increasing.

39 Ten Years From Now: THE CRITICAL POINT Two new filter marshes: Broad Avenue South Goodlette Frank Road. Goal of 1,000 rain gardens attained. Spring Lake dredged d d - Plan to dredge d remainder. Most lakes have aerators and floating islands. Shorelines have native wetland vegetation. ti Residents are beginning to replace sod with native vegetation. ti Stormwater runoff has declined by 50% Irrigation use is down by 30% The bay meets all state standards -- unimpaired.

40 Twenty Years From Now: THE LEGACY All City lakes have been dredged. Lakes are full of wetland vegetation. Yards are native plant gardens. Stormwater runoff captured in yards and swales. No fertilizer needed: compost and mulch. Filter marshes and swales have replaced pipes. Naples Bay is fishable and swimmable.

49 Ten Years From Now: THE CRITICAL POINT Oyster reefs have increased to 50% of pre-development level. Healthy, diverse ecosystem in and around oyster reefs.

50 Twenty Years From Now: THE LEGACY The bay s oysters are edible. Licenses are available for seasonal harvesting. Naples Bay oysters are featured on the p y y menus of local restaurants.

65 Five Years From Now: THE RESULTS Outreach program established educating about mangroves how to plant and trim. Bayview Park is lined with mangroves Gordon River shoal island restored Residents replacing seawalls with riprap

66 Ten Years From Now: THE CRITICAL POINT No new seawalls permitted. Outreach program has homeowners voluntarily planting mangroves. More than half the bay is now lined with y mangroves.

67 Twenty Years From Now: THE LEGACY Mangroves line the shores of Naples Bay. All private properties have mangrove fringes with unobstructed views of the bay Piers coexist with mangroves, extending through and beyond mangrove fringes Residents catch fresh fish for dinner along Residents catch fresh fish for dinner along their mangrove shorelines.

73 Five Years From Now: THE RESULTS Golden Gate Canal diversions lower salinity and seagrasses expand. A new seagrass bed has become established north of Bayview Park.

74 Ten Years From Now: THE CRITICAL POINT Bayview bed has merged with new one. Two successful seagrass beds planted.

75 Twenty Years From Now: THE LEGACY Seagrass beds exist all the way to US 41 bridge. Dense beds of multiple species found at Windstar, Bayview Park, south end of Port Royal, and Cowpens area.

80 Five Years From Now: THE RESULTS Required mitigation provides funds and materials for habitat islands. First island built in the southeastern part of bay.

81 Ten Years From Now: THE CRITICAL POINT Five small habitat islands built on southeast side of bay. The Naples Bay Habitat Islands are favorite close-in fishing spots. Shorebird nesting occurs on islands.

82 Twenty Years From Now: THE LEGACY Naples Bay Habitat Islands support nesting shorebirds and edible oysters. Seagrass beds have formed behind them. Islands provide environmental education p and recreation -- an urban access point to the wild.

83 CONCLUSIONS Twenty years from now, Naples Bay will look quite different than it does today A nonobstructing, low-lying mangrove fringe lines the bay. Small islands, oyster bars, and fishing boats dot its surface. Seagrasses visibly sway in the current. Fish jump and dolphins play in the Gordon River. Locals and visitors sample the local oysters at waterfront restaurants. The State of Florida uses Naples Bay as an example to other municipalities. The people of Naples take great pride in their bay and its The people of Naples take great pride in their bay and its restoration.
