This may include exploring use of different materials, as well as addressing topography challenges and safety considerations for any necessary street crossings. b) a pedestrian sidewalk for all of Mitchell Bridge Road (from ATL Hwy to Tallassee Road) and Timothy Road (from ATL Hwy to the Berkley Hills Subdivision). This may include exploring use of different materials, as well as addressing topography challenges and safety considerations for any necessary street crossings. c) Conceptual plans for each shall anticipate designs for safe pedestrian and bicycle access along Mitchell Bridge Road at each of the two bridges (over the Middle Oconee River and the Loop 10 Bypass). History - For Future Presentation  On September 7, 2021, M&C approved CDO also requested that the Atlanta Highway Corridor User Group develop a recommendation for subprojects for use of approximately $1,500,000 of the TSPLOST 2018 Program Revenues for Project 15 - Atlanta Highway Corridor Improvements. This recommendation should include explanations of subprojects’ alignment with: a) The 2019 Connect Athens Corridor Report for Atlanta Highway; b) The TSPLOST 2018 Project Description; c) The Athens in Motion Master Plan (as applicable for any bike- ped projects, especially with regards to AiM project tiering); d) Public input received for TSPLOST 2018 Project 15 Atlanta Highway Corridor Improvements; and e) ACCGov’s stated goals of equity with regards to project prioritization countywide Area Map Mitchell Bridge Road Timothy Road Shared Use Path Ex.

bridge over the Athens Loop would depend on decision between pedestrian or multi-use trails on the approached  Possible ACCGov-GDOT joint opportunities exist to rebuild existing bridge for vehicle/bike/ped, instead of a stand alone bike/ped structure  GDOT has shown interest in part ACCGov for joint study on Atlanta Highway/Mitchell Bridge Road/Timothy Road intersection for potential

Transportation & Public Works 1 Purpose • Update Chapter 8‐2 (Flood Protection) so that Athens‐ Clarke County can • Adopt new FEMA flood maps and • Continue to participate in the National Flood Insurance Program • Allows residents to purchase federally backed flood insurance. • For presidential declared disasters, impacted residents have access to disaster assistance funds. • ACCGov eligible to apply for federal funds under the FEMA Post Disaster Hazard Mitigation Grant program. 2 1  8/4/2022 History • Athens‐Clarke County has participated in the National Flood Insurance Program ever since unification. • The last comprehensive FEMA flood map update for Athens‐Clarke County was in 1992 • Flood maps were converted to digital form in 2007 3 Recent History: Community Roles & Responsibilities Activity Responsibility Preliminary Issuance FEMA’s Official Draft Map Product. September 2020 30‐day Review Allows affected communities to review the preliminary FIRMs and Flood Insurance Study (FIS), identify any minor issues, and address revisions accordingly Consultation Coordination Officers Meeting organized by GA DNR with the local officials followed by a Flood meeting and Virtual Open House Map Open House for the public to view the preliminary FIRMs. The Flood April 2021 Map Open House will be announced in the community’s local newspaper. 90‐day public comment period Allows citizens to appeal changes in flood zones, floodways and base flood (Appeals Period) elevations, based on scientific or technical issues. Letter of Final Determination (LFD) Stating the preliminary FIRM will become effective in six months. March 15, 2022 Community must adopt a compliant floodplain management ordinance by the maps’ effective date. Six‐month compliance period After the preceding steps are complete and the six‐month compliance 4 September 15, 2022 period ends, the FIRMs are considered effective maps and new building and flood insurance requirements become effective. 2  8/4/2022 Partial Map Scope: Athens‐Clarke County Revision (PMR) 19 FIRM Panels to be Revised New Study Miles • Zone AE: 64.7 Miles Engineering Methods • Zone A: 9.9 Miles • Regression Equations: 74.6 Miles 5 3  8/4/2022 Topographic Data Comparison Typical Effective Study ‐ National Elevation Dataset (NED): Light Detection & Ranging (LiDAR) Data USGS National Elevation Dataset (NED) • Data likely from 1970s (or older) (Example Data: 1ft Variable Point Spacing) (1/3 arc-second; approximately 33-feet) • +/‐ 8ft vertical accuracy • 10m (~33ft) horizontal accuracy RAW DATASETS Oconee Watershed Latest Available LiDAR: Bare Earth TIN created • More Recent: 2010‐2015 by triangulating digital • +/‐ 18cm (~7in) vertical accuracy topography • 4ft horizontal accuracy Cross Sections with FINAL PROCESSED Flood Elevations TERRAIN Ground and water-surface 10 FOOT CONTOURS TINs intersected to identify Artificial 3D water-surface TIN floodplain boundaries created by triangulating flood 7 elevations between cross sections Athens‐Clarke County Draft Results Structures within County Special Flood Hazard Area Community Newly Newly Effective Net Change Added Removed Town of Bogart 0 0 0 0 City of Winterville 1 0 0 0 Athens‐Clarke County 334 25 105 -80 8 4  8/4/2022 Property Owner Notifications Athens Banner Herald Property Owner Notifications ‐ Post Cards 5  8/4/2022 Property Owner Notifications ‐ Post Cards Why FEMA is Undertaking Risk Rating 2.0 • With Risk Rating 2.0, FEMA now has the capability and tools to address rating disparities by incorporating more flood risk variables. These include flood frequency, multiple flood types (river overflow, storm surge, coastal erosion and heavy rainfall) and the cost to rebuild. • Currently, policyholders with lower‐valued homes are paying more than their share of the risk while policyholders with higher‐ valued homes are paying less than their share of the risk. 12 6  8/4/2022 Next Steps • Adopt amended language for Flood Protection Ordinance (Chapter 8‐2). This allows Athens‐Clarke County to continue to participate in the National Flood Insurance Program. • Allows residents to purchase federally backed flood insurance. • For presidential declared disasters, impacted residents have access to disaster assistance funds. • ACCGov eligible to apply for federal funds under the FEMA Post Disaster Hazard Mitigation Grant program 13 Questions? 14 7  8/4/2022 Hydrologic Analysis USGS Regression Equations • SIR 2009‐5043: Magnitude and Frequency of Rural Floods in the Southeastern United States, 2006 • Inputs: Drainage Area • SIR 2014‐5030: Methods for Estimating Magnitude and Frequency of Floods for Urban and Small Rural Streams in Georgia, South Carolina, and North Carolina, 2011 • Inputs: Drainage Area and 2011 NLCD Impervious percent Supplemented with Gage Analysis • Bulletin 17C applied from 50% ‐ 150% of gage drainage area 1% Plus Flows • Combined the average predictive flow error for regression equations with the 1‐percent flows HEC‐HMS • To model storage along Sandy Creek and Malcolm Branch • NOAA Atlas14 rainfall estimates • SCS Curve Number for losses • NRCS Unit Hydrograph for transform • Muskingum‐Cunge for reach routing 16 8  8/4/2022 Hydraulic Analysis FEMA Standards FEMA Technical Study Data Notebook Hydrologic Flows 17 9  8/4/2022 FY23 LIVE STREAM PIPE REPLACEMENT PROGRAM UPDATES & PROPOSED CULVERT REHABILITATION/MAINTENANCE LIST MAYOR & COMMISSION WORK SESSION AUGUST 9 2022 PRESENTATION BY: ACC TRANSPORTATION & PUBLIC WORKS DEPARTMENT 8/9/2022 1 PURPOSE • PRESENT PROGRESS MADE ON THE LIVE STREAM PIPE AND CULVERT REPLACEMENT PROGRAM TO DATE • SEEK INPUT ON PROPOSED FY23 REHABILITATION PROJECT LIST UTILIZING ALTERNATIVE REHAB IN LIEU OF OPEN CUT REPLACEMENT April 2019 September2020 July 2022 Existing Culvert - Woodhaven Drive 8/9/2022 2 1  8/4/2022 PROGRAM HISTORY Conceptual Cost Actual Cost – SEPTEMBER 2020 – M&C APPROVED 55 PROJECT No. Street Name/Address Estimate Streets & Drainage Div.
