1 Neighborhood Dredging SSD Program Brief to Beaches & Waterways Commission August 4,

2 Neighborhood Channel Dredging Program Initiative Supports City Council Goal #4: Revitalize Neighborhoods and Plan for the Future Re-establish Use of Navigable Channels Improve Water Quality 2

3 Prior Efforts / Reviews 1997 Citywide Analysis Too big, too long, unaffordable Series of 4 Council Briefings Four potential courses of action identified No formal council action 3

4 Status quo Historic Alternatives Basin wide SSD : properties, $3M/yr + 10 years completion, $30M in 1997 dollars Expand City main channel projects to include spur channels: no ROI via confirmed neighborhood spurs, + $4million Cost sharing on a single dredging basis: 65/35 but not all coves were the same Fully funded by City: takes ownership = $35M in 2005 dollars 4

5 Hybrid Alternative: Adopted by City Council in the FY12 Resource Management Plan (Budget) Individual neighborhood SSD s, specific scopes and timelines (3 cycles, 16 years) Includes City - funded Spur Channels (early appropriations allow for 1 st dredging in year 2) Financial Partnership - Cost sharing (3 sources) City management of effort formulation, funding, design, permitting, construction, maintenance Creates a viable solution to reclaim navigation & improve water quality Establishes a reasonable timeline with visible results 5

6 Legal Considerations VA Code Authorizes SSDs for navigation Minimum of 51% property owner approval Formal adoption by City Council Council preference: 80% property owner approval 6

7 Neighborhoods In Play 1. Old Donation Waterway 2. Bayville Creek 3. Robin Hood Forest 4. Thoroughgood 5. Chesopeian Colony 6. Harbour Point 7. Baycliff 8. Hurds Cove 9. Middle Plantation 10. Buchanan Creek 11. Shadowlawn 7

16 Current Proposal Financing Strategy Neighborhood channel funded by SSD City cost share s by funding spur channel Individual funding of turn basins City management of project Economies of scale Defined schedule Sunset duration 3 Funding Sources 16

17 Project Format Mechanical Dredging Potential for neighborhood dredged material transfer City Dredged Material Transfer Site Network Deposition at City Disposal Area: Whitehurst Borrow Pit 17

18 Neighborhood Channel Dredging POTENTIAL MECHANICAL DREDGING TRANSFER SITES Maple Street Crab Creek Long Creek & Broad Bay Upper Western Branch Lower Western Branch Former Recording Studio Eastern Branch V.B. Blvd. Laskin Road Linkhorn Bay Whitehurst Dredged Material Placement Area 18

19 Dredging Cycles Initial dredging: 2 years after SSD adoption Projected cycle: 7 years 2 nd cycle anticipated at 70% of initial volume 3 rd cycle anticipated at 50% of initial volume 1 st Dredging 2 nd Dredging 3 rd Dredging Year

20 1 st Dredging Cost Estimate City Portion: $489,000 SSD Portion: $1,062,000 Individual Channels: $5,000 average 1 st Dredging engineering and construction contract could reach $2,000,000 Includes design, administrative costs, survey, construction and navigation aids 20

21 Life Cycle Estimated Costs City Portion Cycle Volume Cost 1 29,500 CY $488, ,650 CY $458, ,750 CY $460,797 64,900 CY $1,407,967 (includes 5% cost escalation) ($30, $40.20, $56.57) 21

22 Life Cycle Estimated Costs SSD Portion Cycle Volume Cost 1 13,576 CY $1,062,000* 2 9,503 CY $996, ,788 CY $1,001,289 29,867 CY $3,059,445 (includes 5% cost escalation) * Does not include initial navigation aids costs 22

23 Appropriations Schedule Cycle Year Design Construction 1 1 $300,000 2 $1,255, $250,000 9 $1,205, $250, $1,210,000 Total $800,000 $3,670,000 Neighborhood & City channels only = $3,670,000* * Does not include initial navigation aids costs 23

24 SSD Data Total SSD assessed value: $91,271, properties in the neighborhood district Each penny surcharge raises $9127/year SSD rate covers costs for 16 year life: /$100 of the FY12 assessed value Average property contributes $1,170/year Review rate at end of every 4 th year 24

25 Timeline 2 years from SSD adoption to first cycle of dredging for engineering, real estate and permits 2 nd and 3 rd cycles each 7 th year thereafter Review costs, assessments and SSD rate every fourth year Sunsets in 16 th year 1 st Dredging 2 nd Dredging 3 rd Dredging Year

26 Funding/Financing Escrow SSD funds for 2 years before 1 st dredging General Fund underwrites first dredging SSD payback within 16 year life Establish Reserve Fund for pre-engineering Revisit SSD rate every 4 th year Staffing Required FY 12 1X Project Engineer FY 13 1X Project Engineer and 1X Inspector 26

27 Risks Environmental permits Encroachment approval Real estate dedication Real estate valuation changes Cost escalation assumption (5% annually) 27

28 Initial Neighborhood Brief Agenda Items Provide Program Overview Explain the concepts of the SSD Define the three elements of financing Describe the preliminary engineering estimates Review the calculation assumptions & formulas Provide the initial SSD estimate ( /$100 assessed value) Respond to questions 28

29 Post Initial Neighborhood Brief Action Items Explore dredged material transfer sites Determine extent of potential mitigation Brief City Council on project Staff authorization Validate willingness to reach 80% Execute documentation Public hearing City Ordinance establishing SSD 29

30 Next Steps for Program Annual Services Consulting Contract SSD Ordinance Template Preparation Environmental/Regulatory Coordination Commence Individual Project Engineering 30

31 City Council Referral to: comprehensively study the issue of dredge spoils removal and transfer stations The feasibility of alternative dredging methods, such as hydraulic rather than mechanical dredging; The potential for beneficial re-use of spoils; Opportunity for public input from all concerned citizens with at least one facilitated structured meeting for public input; An analysis of the impact on affected communities (both those receiving dredging and those in the vicinity of the existing and proposed transfer stations) with a focus on identifying sites that are sufficient to support the needs of the project but have the least potential for adverse impact for the community; and A proposed framework with parameters for operation of the spoils sites, including potential use of the site by the public for dredging by entities or individuals other than the City.
