Kosoy, P.E./Director of Public Works ~~~~ DATE: August 18, 1999 BACKGROUND: After the City's Stormwater Master Plan was completed in 1995, the City contracted with England, Thins & Miller, Inc. to, among other tasks, design a stormwater collection system for the Core City. This design was completed in January, 1998. Due to a strong interest among the citizens regarding environmental impact of the project, the City decided to modify the design. In addition, the City decided to include design of structures foi tailwater control. Requests for Proposals (RFPs) were advertised October 21 and 25, 1998. Seven proposals were received on November 18, 1998. After engineering presentations on December 4, 1998, the City Commission selected the top three firms deemed to be the most highly qualified to perform the required services: 1. The R-A-M Professional Group, Inc. 2. AiI:enhead & Odom, Inc. 3. Gee & Jenson, E-A-P, Inc. On December 13, 1998, the City Commission awarded a contract with the firm deemed to be the most highly qualified to perform the required services, The R-A-M Professional Group, Inc. (R-A-M) for a Preliminary Design Report. This report was completed bn March 17, 1999. On April 12, 1999, the City Commission directed R-A-M to revise the report to indicate what level of service could be provided within our budget limit of $9 million. The revised report was delivered on May 7, 1999. On August 4, 1999, the City received a letter from R-A-M releasing the City from any further obligations on their existing contract due to the inability to negotiate the Phase II (Final Redesign) component of the project. On August 9, 1999, the City Commission authorized staff to negotiate a contract for final redesign of the project with the next most qualified firm, Aikenhead & Odom, Inc. The authorization was for City staff to negotiate the contract in rivo phases, for preliminary and final redesign. Staff has negotiated with Ail:enhead & Odom, Inc. and agreed on a cost of $48,500.00 for the preliminary design phase of this project, to include records research, a review of previous modeling, a detailed site reconnaissance, interviews with residents to obtain anecdotal water Levels, marking of high water lines and subsequent survey of those levels. The resulting report will include a compilation of this information with a proposed course of action for final design and a conceptual budget. The preliminary phase will be completed within 45 days of notification of contract award. Funding for this engineering work is from the Utility Revenue Bond Fund 480-0000-533-6300, which has a remainmg balance of $5,801,774.00. RECOMh1ENDATION: Award the contract for the preliminary redesign phase of the Stormwater and Utility Project to Aikenhead & Odom, Inc., in the amount of $48,500.00. Authorize the City Clerk to notify the firm of the award, and authorize the City Manager to sign the contract with Aikenhead & Odom, Inc. ATTACHMENTS: 1. Letter dated August 4, 1999 from The R A-M Professional Group, Inc., releasing the City from obligations under our existing contract. 2.

While there are obviously numerous factions deeply involved with many details of this investigation, as I indicated to the Mayor and City Council on August 9, we always welcome review and criticism of o}ir work. We are very confident we can provide in-depth analysis and design services which wig 1 result in the betterment of the entire City. Attached is our proposed Scope of Services and Fee Proposal for the initial phase of our design. As will be seen from the attached, we have minimized our cost (fee) to the City for this phase of the effort, and have simultaneously indicated a strong commitment to achieve what we perceive to be the goals of the City. Certainly one of the more important goals is to fall within the City's budget, and we are totally committed to that goal. We have already begun the process of detailed analysis and innovative thinking which we feel will lead us to acost-effective, community-acceptable solution to the difficulties which are being experienced. If you have any questions regarding any of the above or attached, please call me at your earliest convenience. We look forward to starting the process of solving problems!

CITY OF ATLANTIC BEACH, CAPITAL IMPROVEMENTS PROJECT SCOPE OF WORK SUMMARY Engineering Design, Phase One, Project Approach Aikenhead & Odom, August 18, 1999 Page 1 of 3 Aikenhead & Odom (A&O) will provide Engineering Design Services (Design) to the City ofAtlantic Beach (City) for a Capital Improvements Project (Project) involving analysis of, and eventual design of modifications to, the existing City-wide master stormwater system, the Core-City street and drainage system, and select Core-City water distribution systems. Sanitary sewer system modifications/design will be accomplished by City forces independently of A&O effort. Design will be accomplished in two (2) phases, a Project Approach phase and a Final Design phase. Specific scope and associated fee for the Final Design phase will be developed following completion of the Project Approach phase. This scope will detail the effort to be accomplished under the Project Approach phase. A. Analysis of Existing Data, Records, Designs, and Survey Information: A&O will review and analyze all•Gty-provided copies of available master drainage reports, data, record drawings, designs, correspondence, permits, grant applications, complaint letters and information, and other available pertinent information. A&0 will also interview, )d based on concurrence by City Public Works staff, those persons known to be familiar Q with current stormwater problems. A&0 will meet with the City Stormwater Review ~ ~ Committee (SRC), in conjunction with City Public Works staff, to obtain all /~,,~~l~d information and input that committee will offer. A&O will compile all information ~'_•/ and provide a written summary analysis of the existing data background as it will pertain to the A&0 analysis and Design. B. Analysis of Existing Drainage Models: A&O will review and analyze City-provided digital copies of the ETM-modified CHZMHiII ICPR 1.4-version model and the ' R A-M-modified CDM SWMM City of Jacksonville-version model to determine anticipated suitability, strong points, and weak~points of each. A&0 will advise the City of a recommended hydrologic/hydraulic model(s) which will best suit the~City's purposes for A&O Final Design. C. Critical Elevation Data: A&0 will, with City personnel, interview Core-City residents where flooding is known to exist. The interviews will determine specific locations at various home-sites where high water has been known to rise (anecdotal data). These specific locations will be' marked by A&O, and A&O will obtain the services of, and _ coordinate with, a surveyor to obtain elevations of these locations. Elevations will be "benched" to the same datum as the existing design records datum. ...r'--- ----' __... - City of Atlantic Beach, Capital Improvements Project Scone of Work Summary . Engineering Design, Phase One, Project Approach , Aikenftead & Odom, August 18, 1999 Page 2 of 3 D. Master Concept Mapping: A&O will develop a Concept Map, Existing Conditions and a Concept Map, Preliminary Proposed Conditions. The Existing Conditions map will use a digital aerial background and will show soils information from SCS Soils Map data, overall topography from USGS 5' contour information, specific topography as available from existing records and/or design(s), available plat and record drawings information, data on existing critical stormwater conveyance facilities, and field data as available and obtained. The Preliminary Proposed map will utilize the Existing Conditions map as background, with preliminary concept overlays of proposed improvements and/or modifications to the master stormwater system and Core-City. E. Report of stormwater Options: A&O will develop a summary report ofthe found conditions, anticipated best course of action, possible alternative course(s) of action, a preliminary estimate of the anticipated return-storm level-of-service and very preliminary budget range of anticipated cost of construction for the proposed actions and possible alternative(s). Accuracy of anticipated level-of-service and budget range cannot be conclusive until a suitable stormwater model is agreed upon, correlated to existing design datum, and alternative scenarios run. However, it is important to note that A&O has extensive experience in stormwater modeling and stormwater system analysis and design. Even at this Pre-Project Approach phase point in time, A&0 has obtained substantial specific data and anecdotal information on the City system and Core-City condition. The Project Approach phase will provide confirmation or denial of many of our current concepts. Based on information currently in hand, and from our experience, we currently anticipate the following improvements are possible to be achieved, resulting in a viable and cost-effective resolution of the existing City~stormwater conditions: 1. An economical pumping system (50 - 150 CFS, short-discharge), gravity tidal-control gate, community-acceptable expansion of existing Selva Lagoon storage capacity, and nominal improvements to existing constrictions within Selva Lagoon can achieve a tailwater control with acceptable conditions throughout the City. 2. Innovative design and modeling techniques within the Core-City, in conjunction with the tailwater control improvements, are expected to substantially improve Core-City conditions, with virtually no flooding of homes (100-yr FEMA storm possible exception in particular cases), and for a smaller event storm only minimal flooding of yards and occasional street flooding with rapid subsidence of water following a storm event.

It is preliminarily anticipated minimal disruption/impact to Howell Park, Preben Johansen Park, and existing Core-City streets will be necessary to aclueve the above conditions. We anticipate achieving this using the following preliminary concepts: a. Howell Park is currently anticipated to require some hydraulic improvements to the existing primary drainage-way, with an associated method of access for maintenance purposes. These improvements will be designed in conjunction with the City's arborist to minimize impact to existing trees/shrubs, maximize planting and repair of disturbed areas to restore to every practicable extent the existing visual and audio serenity, and utilize best available techniques to allow the maintenance access to be an aesthetically-acceptable footpath when not being used for maintenance purposes. b. Preben Johansen Park is currently anticipated to be used essentially as-is, with a tailwater control structure to allow nominal storm events to pool within the existing park for stormwater treatment without disruption to existing park use or visual conditions;' 1 c. Core-City'streets are currently anticipated to be designed providing resurfacing-only wherever possible, using inverted-crown section wherever feasible in areas where reconstruction is required, and minimizing piped stormwater conveyance systems by allowing in-street flow to occur for storms greater than summer showers wherever practicable.
