LTC 037-2012 Dune Maintenance and Restoration Program Update ® MIAMI BEACH OFFICE OF THE CITY MANAGER R F C F I V r NO. LTC # 03;-2012 LETTER TO CO&WI O- PPH 3: 32 TO: Mayor Matti Herrera Bower and Members of the City Commissio CI CLERK'S OFF ICE FROM: Jorge M. Gonzalez, City Manager DATE: February 7, 2012 SUBJECT: Dune Maintenance and Restoration Program Update This Letter to Commission (LTC) provides an update regarding the Dune Maintenance and Restoration Program within the City. The City has developed a Dune Maintenance and Restoration Work Plan that prioritizes sections of the dune for restoration through the removal of non-native vegetation and replanting of native vegetation. This plan also includes scheduled dune vegetation maintenance. Background The dunes are the vegetated buffer parallel to the shoreline that were installed by the Army Corps of Engineers in the late 1980's to protect upland properties and prevent beach erosion. Native, salt-tolerant vegetation stabilize the dune and help accrete sand, which helps prevent erosion of the beach system and protects properties from the effects of coastal storms. In addition, beachfront vegetation protects sea turtle nesting habitat from urban light pollution. On September 10, 2003, the City entered into the Beachfront Management Agreement with Florida Department of Environmental Protection (FDEP) to manage the sandy beach area lying east of the erosion control line and belonging to the state of Florida, from Government Cut north to 87th Terrace. Under this Agreement, the City is named the lead managing agency for the beach area with support from Miami-Dade County on beachfront maintenance issues, including litter control in the dunes and trimming of public beach entrances. Therefore, under this agreement the City has the authorization to perform projects that contribute to erosion control and dune restoration, including invasive or non-native species removal and selected native species trimming, where applicable. Dune Maintenance & Restoration Program To fulfill the Citywide Dune Restoration and Enhancement Program, the City conducts the following proactive dune maintenance activities: 1. Interdepartmental dune inspections; 2. Vegetation maintenance; and, 3. Volunteer dune restorations. These activities reduce the potential for illegal activities and homeless encampments, remove invasive vegetation that threaten the integrity of the dune system, aid in the conservation of the plant and animal communities that inhabit the dune system, and preserve the vital storm surge protection and erosion control functions that the dune system provides. Interdepartmental Dune Inspections Starting in October 2011 the City began conducting monthly inspections of the dune system to prioritize maintenance activities. These monthly inspections include representatives from the Environmental Division, Greenspace Management Division, Property Management Division, Sanitation Division, Police Department, Code Compliance, Ocean Rescue, Homeless Outreach LTC—Dune Restoration and Enhancement Program February 7, 2012 Page 3 of 3 Team, and Miami-Dade County Parks & Recreation. The purpose of these inspections is to identify problem or hotspot areas of overgrown vegetation, cleanliness issues, and homeless activity. Attachment A details the responsibilities and procedures for on-going dune maintenance that is prioritized based on these monthly inspections. Vegetation Maintenance Any alteration, trimming or removal of vegetation in the dune system must be approved by FDEP. The Public Works Department's Environmental Division coordinates the permitting process with FDEP to ensure the City is in compliance with all state and local regulations. Once permits have been obtained, the Parks and Recreation Department's Greenspace Management Division is responsible for conducting selective trimming and removal when life safety concerns are identified and retaining landscape maintenance contractors to conduct large scale trimming and removal. Regular dune maintenance is not currently included in the City's full service landscape maintenance contracts for the Beachwalk, Boardwalk and Spoils; however, funding has been recently identified to establish a maintenance program to address both recently restored dunes and conduct selective trimming of native species. In FY 2010/11, $50,000 was appropriated from the Capital Investment Upkeep Account (CIUA) to begin dune maintenance activities, which encompassed installation of beach signage, rope and post, sand fencing, and removal of invasive vegetation from 14th Street to 23`d Street. In FY 2011/12, $17,197 of the $50,000 budgeted was spent to address invasive vegetation removal from South Pointe Park to 1s' Street and from 75th Street to 73`d Street. Photographs from the recent maintenance activities are depicted in Attachment B. For FY2011/12, the remaining balance will be used for selective trimming and pruning Citywide and to replant the areas where removals have been conducted. The CIUA Expenditures for FY 2010/11 and FY 2011/12 are detailed in Attachment C. On January 13, 2012 the Greenspace Management Division issued a request for quotes (RFQ) to the three current landscape maintenance contractors to remove invasive plants, install native dune vegetation, and provide long term maintenance with proactive trimming and an non-native plant removal schedule for the dune system (Attachment D). ValleyCrest Landscape Maintenance, Inc., provided the most competitive response. The Dune Restoration Work Plan in Attachment E prioritizes each area based on the findings from interdepartmental inspections, identifies basic site conditions related to invasive vegetation, and provides removal with replanting costs provided by ValleyCrest. While this removal, planting and on-going maintenance has an initial upfront cost, it will save money long-term by eliminating the necessity of conducting future expensive, large-scale removals and will prevent invasive vegetation from re-establishing in restored locations. The Administration will be requesting funding for this long term maintenance program during the FY2012/13 capital budget process. In the interim, the City has established a two part maintenance program to address current vegetation maintenance concerns Citywide. Both phases of maintenance will occur concurrently. The first component includes the three locations where removal activities recently occurred (South Pointe Drive to 1St Street, 14th Street to 23`d Street and 73`d Street to 75th Street). For these areas, Superior Landscape & Lawn Service, Inc will begin full maintenance activities by providing thirty (30) service visits annually that include: • the physical removal of all non-native species; • supplemental watering of newly installed plant material; • supplemental litter services (Miami-Dade County provides primary litter services); and, • selective pruning of native trees in accordance with FDEP guidelines. LTC—Dune Restoration and Enhancement Program February ;, 2012 Page 3 of 3 The second component of the maintenance program targets the hotspot locations that are identified through the interdepartmental inspections and have yet to be restored with a removal and planting. Once a hotspot is identified, the Environmental Division will obtain the necessary state permits and the Greenspace Management Division will retain a contractor to conduct selective native trimming and supplemental litter control. Attachment F details the maintenance costs for this program. Volunteer Dune Restoration Since 2006, the City has facilitated thirty (30) volunteer dune restoration events, which have consisted of a combination of invasive vegetation removal and planting of native species. Attachment G details the volunteer dune restorations in 2011 and anticipated 2012 events. The majority of dune restoration events have been carried out by Surfrider Foundation and Fairchild Tropical Garden, who supply volunteers and materials, and the in-kind services from the Parks & Recreation Department and Public Works, Sanitation and Environmental Divisions. There are four removal events scheduled over the next two months; including, Florida Power and Light who has offered to provide 34 volunteers for a removal event in North Shore Open Space Park at 791h Street on March 15.
