2 ST. JOHNS COUNTY PUBLIC WORKS DEPARTMENT ENGINEERING DIVISION 2740 Industry Center Road St. Augustine, Florida I N T E R O F F I C E M E M O R A N D U M TO: FROM: SUBJECT: Neal Shinkre, PE, MBA, Public Works Director Jay Brawley, PE, AICP, County Engineer Hurricane Irma Impacts and Unplanned Drainage Projects DATE: January 25, 2018 Background: Early September 2017 most of Florida and all of St. Johns County was severely impacted by Hurricane Irma. The County experienced widespread flooding due to a confluence of conditions that included unprecedented rainfall, higher than predicted tidal ranges, and hurricane force winds. The magnitude of these combined conditions exceeded the textbook 100-year storm event and created flooding and related impacts that have not been experienced in recent memory. Naturally, this situation generated a significant increase of drainage issues reported to Commissioners and County staff. Early Response: Public Works provided an immediate response to resident complaints with our Road and Bridge (R&B) division being the front line responder. Resident complaints and concerns were logged for tracking followed by field verification of the complaint. Maintenance related items such as debris removal and clearing blocked drainage were handled by R&B crews as quickly as resources allowed. However, large capital repairs or items that required design or detailed analysis, beyond the normal scope for R&B, were deferred to County Engineering. The drainage issues that were reported by residents not only included project areas previously reported (that had conditions exacerbated as a result of the storm) but also project areas that had failed infrastructure or no infrastructure at all. In an attempt to track and methodically review these problem areas in a consistent manner, the Engineering Division has created a Countywide Stormwater Initiative (CSI). The CSI team aims to identify, understand, and propose necessary improvements to areas that have been impacted by the 2018 storm season. A map of all the project areas is included as Exhibit A. Existing Drainage and Stormwater Programs In addition to the day-to-day operations and maintenance, drainage and stormwater assets require major repairs, replacements (R&R) and modifications. This capital R&R is currently managed via the Public Works Asset Management Program. The Asset Management essentially utilizes a scoring system that reviews various elements for over $250 million of stormwater and drainage assets and prioritizes R&R. Project emergencies encountered during the year that impact safety are also funded via this program. Projects that require detailed studies, real estate acquisition, or

3 are estimated to be over $200,000 are typically directed into the Capital Improvement Program (CIP). Exhibit B provides a more detailed description of these programs. The Asset Management Program is currently budgeted via the Countywide Drainage Infrastructure and the Countywide Stormwater Maintenance budget line items. Over the past several years these programs have been limited to around $1 million each year and are primarily focused on repair and replacement of aged and failing culverts. For FY 2018, approximately $1.14 million was budgeted for these programs. Exhibit C provides details of the FY 2018 budget, status of encumbered funds, and available balance. The identified CSI projects include drainage and stormwater issues that are a result of aged and failing infrastructure, limited infrastructure, lack of infrastructure, or issues exacerbated due to record rainfall from the storms. CSI projects as a result of failed infrastructure essentially fit the Countywide Stormwater Maintenance and Infrastructure programs, however, CSI projects as a result of limited or lack of infrastructure may have to be funded by other revenue sources and the CIP. Currently, there is no funding available for such projects via the CIP. Emergency Actions: The initial wave of CSI projects included four projects that created hazards and safety concerns at the bridges on Roscoe Blvd. and Racy Point, and culvert failures at Captain s Point and Cecelia Court. These projects required immediate action and subsequently were completed utilizing approximately $1.1 million from TTF reserves. The CSI Projects: The projects under evaluation by the CSI range significantly in scope, cost, and size of geographic area. Some of these projects have been identified as legacy issues that were analyzed in the past. This provided an opportunity to expedite certain areas where due diligence and potential options were already available. Problem areas such as Winton Circle and Porpoise Point are examples of legacy issues and they were able to advance more quickly than some areas that required more research and data gathering. Therefore, the schedules for projects will vary with additional engineering reports or preliminary designs completed over the next few months. Projects that were identified as needing immediate repair were initiated for design. Exhibit D provides a list of the projects and a status indicating if the project has been initiated for review, a study has been completed, or design has commenced. Project preliminary design costs to identify the issues and provide preliminary assessments are anticipated to be approximately $400,000. Although a final report has not been completed, combined design and construction costs may be in the range of $6 million to $8 million. The FY 2018 budget could not anticipate these unplanned needs. In an attempt to complete review, analysis, and initial assessment and understanding of these impacts, funds were borrowed from the General Engineering Operating budget. Since the FY18 General Engineering Operating budget is limited to $360,000, an operating budget deficit of $40,000 is anticipated. Additionally, engineering of other projects that were previously planned under this category have been deferred. The next steps include refining options for the projects that are further along in analysis, meeting with stakeholders to communicate project status, reviewing designs and studies, and pursuing alternative funding sources. Additionally, County staff is actively working with programs for the Hazard Mitigation Grant Program (HMGP), Community Development Block Grant (CDBG), and FEMA. These programs are designed to accommodate disaster recovery reimbursements; however, low probability of funding is anticipated from these programs.

4 Summary Several communities have been impacted due to flooding from the storms, nor easters and heavy rains. Impacts are primarily due to either lack of infrastructure or failure of aged drainage and stormwater assets. Projects vary in scope, cost and size of geographic area they cover. In the next few months, Public Works Engineering plans to complete the assessment, preliminary designs, and summarize project scope for most of these CSI projects. In order for these projects to move forward into construction, funding needs to be identified. The current FY 2018 Budget is limited to $1.14 million ($1 million is encumbered) and is only focused on Asset Management Program (replacement of aged and failing culverts). This program itself has a backlog of deferred maintenance of approximately $2.5 million per year (for the next 10 years). Funds may have to be utilized from Reserves or an alternative funding source may have to be determined. Board direction will be needed to address funding for these critical projects.

5 Exhibit A

6 Exhibit B Countywide Drainage Infrastructure Program There are many pipe systems throughout the County that are reaching the end of maintainable life due to soil conditions or age. The Countywide Drainage Infrastructure program provides a comprehensive analysis of the existing drainage infrastructure assets. Replacement projects are based on a prioritized list. The prioritization is based on asset age, inspected condition, stormwater drainage criticality, pavement management project coordination, and complaint history. Investing in infrastructure reduces flood risks, protects public safety, improves surface water quality and enhances our community. Countywide Stormwater Maintenance Each year numerous drainage problems requiring immediate response to alleviate flooding or otherwise protect the health, safety, and welfare of the County s residents are brought to the attention of the Public Works Department. Examples include, but are not limited to, flooding on public properties, flooding on roadways, standing water in ditches or drainage facilities, and damage to existing drainage facilities. This funding allows flexibility to quickly respond and address these unforeseen and otherwise unfunded issues. Projects can be located anywhere in the County that drainage problems arise, hence the designation Countywide. Work includes preliminary engineering, design and permitting, and construction as needed on a case by case basis. Capital Improvement Plan (CIP) St. Johns County recognizes the need to keep pace with the growth of the community and the needs of the County s residents. The Capital Improvement Plan is designed to identify the public facility and infrastructure needs of the County and create and manage a timely and cost-effective replacement plan. A capital improvement project will be created for complex projects that includes full engineering design, permitting, land acquisition, and construction. Capital Improvement projects will be part of the Public Works budget that would receive approval by the Board of County Commissioners through the budget process. Usually these projects become a part of the County s fixed asset inventory upon their completion. In addition, the County may include consultant studies in the CIP if the cost is also anticipated to be significant.
