Home My WebLink About07 - Alternatives Development and CIP PrioritizationCity of Sebastian Stormwater Master Plan Update 7 Alternatives Development and CIP Prioritization 7.1 Previously Identified CIP Projects Many Capital Improvement Program projects were identified in previous Master Plan updates and the full scope and budget estimates for the projects were sometimes unclear. Some of the projects are currently included in the City's Capital Improvement Program for the Stormwater Fund, and for those the scope and status of the projects were reviewed with City staff and evaluated against current modeling results to determine if they should continue to be included in the CIP program. Table 7-1 shows the previously identified projects that were eliminated from the CIP program or replaced with a new or modified project scope. Table 7-1.

Due to erosion of the side slopes, this ditch is difficult to maintain and needs to be improved. The system drains the entire central section of the City and therefore is critical to maintain flow and avoid flooding. Stonecrop The project has been redesigned for open Drainage Ditch conveyance, versus piping, which substantially reduces the estimated costs. A FEMA Hazard Mitigation Grant is being pursued to provide 75% of the expected costs. Stormwater Funds of $215,000 are being allocated for the grant matching amount. Blossom Ditch No description Pipe Identified in 2013 SWMP (Bevan & Laconia culverts) @ $1 M. Shown in current CIP at $860k FY20.

Improvements Outfall/clear outfall area 7.2 Current and Proposed CIP Projects The following is an updated list of proposed CIP projects identified through the modeling work in this Master Plan, those included in prior Master Plan updates and those identified through discussions with City staff. The goal is to produce a 10-year CIP program with the most feasible schedule and strategy to fund those improvement projects with the highest priority and the greatest benefits to the City. The H&H Model was used to evaluate various CIP projects and develop initial recommendations to address drainage issues and reduce surface flooding for the 25yr-24hr design storm event. See Section 3.7 for a detailed explanation of H&H modeling results. The CIP projects were evaluated based on surface flooding reduction, open channel flooding reduction, and cost effectiveness. Design and implementation of the CIP projects should include a review of available survey data, system conditions, and constructability. Table 7-2.

Copies of the estimates are included in Appendix I. 7.3 CIP Prioritization Process/Tool The method for prioritization of maintenance issues was presented in Section 6. CIP prioritization follows a similar methodology but is more detailed and results in a more thorough triple bottom line (TBL) type cost -benefit analysis that considers economic, social and environmental effects. Upon identifying a CIP need, the project priority should be determined by the City Engineer. Issues that without capital improvement pose a safety hazard or create a condition that prohibits the proper function of the SWMS should be prioritized over aesthetic or preventative projects. The amount of time required to address CIP projects ranges from a few weeks to months or even years depending on the severity, complexity, and priority of the project. In certain more complex emergency www.arcadis.com 113 City of Sebastian Stormwater Master Plan Update cases, temporary resolutions should be presented as a stop -gap measure to address public safety or functional issues while a more permanent resolution is determined. The CIP Priority scoring uses a simple calculation to weight the importance of a proposed project based on economic, social and environmental criteria. For each of those three criteria, a criticality score and project effectiveness score is determined through a series of scored queries and an overall percentage of total category score is calculated to determine its priority. CIP projects having the highest overall percentages are the highest priority projects. In the CIP Priority calculation, the score weighting was as shown in Figure 7-1. Economic 0.28 0.32 Social 0.30 0.32 Environmental 0.42 0.36 TOTAL 1.00 1.00 Figure 7-1. CIP Priority Criteria Weighting Once the proposed CIP projects shown in Table 7-2 were identified, scoped, and cost estimates were prepared, a CIP Priority scorecard was prepared for each of them to determine their overall priority ranking. An example of a project scorecard is shown in Figure 7-2. A summary of the final priority scoring is shown in Figure 7-3, and a graph of the final Criticality vs. Effectiveness scoring is shown in Figure 7-4. www.arcadis.com 114 City of Sebastian Stormwater Master Plan Update City of Sebastian Capital Improvement Project Benefit Cost Analysis Scoring Template Project No: 13 Description: Concha Dam Repair Criticality of Issue for LOS Project Effectiveness Criteria Score Description Contexi Score Description Context ECONOMIC 111111M Criticality of Projei Issue for LOS 0 > $10,000,000 2 $5,000,000-$10,000,000 I I 4 $3,000,000 - $5,000,000 (What is the cost (to the City) of the proposed Project Cost 5 $1,000,000 - $3,000,000 project? 8 $500,000-$1,0001000 10 $100,000 - $500,000 12 <5100,000 0 Ve(Y Low 0 Ve(Y Law 1 4 Low (What are the economic impacts (future flooding 1 2 Low lWhat is the potential benefit ofthe proposed Economic Impacts 8 Medium (damages, etc.} ifthe flooding orthe asset 4 Medium projectto increased opportunities for economic 10 High (condition is not addressed? 6 High (development or community enhancements? 12 Very High 8 Very High 0 Excellent 0 No Condition of Existing 1 Good (What is the condition of existing pmate 1 Limited (Will the proposed project fix the private asset Infrastructure Private 2 Fair infrastructure assets in the project area? 2 Partially (conditions in the project area? 3 Poor 3 Mo�}ly 4 Very Poor 4ComeLely 0 Excellent 0 No 4 Good 2 Limited Condition of Existing iat is the condition of existing public i re proposed project fix the public asset Infrastructure Public 8 Fair , �„_L, i the project area? 4 Partially the project area? 10 Poor 5 Mostly Economic Subtotal 28 Very Poor Completely to 0 0 ❑ 0 10 10 18 SOCIAL 0 No potential for injury f loss of life G No 2 Limited potential for injury (What is the current impact on safety from 1 2 Limited (Will the proposed project minimize the impact Safety 4 Some potential for injury! loss of life floodingrassett condition in the project area for 4 Partially on safety in the project area for the intended he intended level of semce? fi Mostly =vel of semce? 6 Reasonable potential for nju iry 8 Great potential hor injury! loss of life 8 Yes 0 None 0 None Number of Properties 1 1 to 5 IHaw many properties are currently impacted by 1 1 to 5 IHaw many properties will have postively Impacted 2 6 to 10 floodingrasset condition in the project area for 2 6 to 10 heneflted from the project for the intended Level I 3 11 to 15 Ithe intended Level of Service? 1 3 11 to 15 lof Service? 4 Greater than 15 4 Greater than 15 ial impact 0 No Traffic Flow on Public 0 No potentHow is traffic affected b °...' . -:: , ... \ Will the proposed project positively affect traffic Streets 2 Se�gpdaryYsem 1 Alternatives Exist fin the project area? 2 Y1N� and flooding conditions in the project area? 4 nmary Vs, em!
