OVERVIEW
In a continuing effort to monitor and report on the functionality of The Arborwood Stormwater Management System (SWMS), an inspection of the SWMS was performed in February and March of 2018. Inspections included field observations of all lake banks within the Bridgetown Phase of the Arborwood SWMS to determine the extent of existing stabilization and any areas of erosion. This report outlines the observations made and identifies areas of concern which need maintenance/repair, and any recommended additional inspections/monitoring.

GENERAL PROJECT INFORMATION
Project Location: Arborwood, Lee County, FL
SFWMD Master Permit No.: 36-04853-P
Dates of Inspection:
o	Lake Banks: February/March 2018 (field observation by J.R. Evans Engineering, P.A.)

LAKE BANK INSPECTION
Field observation of the lakes within the Bridgetown Phase of the Arborwood SWMS was performed in February and March  2018.  All  lakes  within  the  Bridgetown  Phase  were  inspected.  Lake  stabilization consists of grassed shorelines at varying slopes.

Within the Bridgetown Phase of the SWMS, there were areas of erosion noted on grassed shorelines, including areas of minor erosion that require maintenance/repair to prevent substantial erosion or failure, and areas of extensive erosion that require immediate corrective action to remediate the shorelines. It is recommended that corrective action is taken to remediate shorelines identified as having “minor erosion” and “extensive erosion” within this report.

Included as Exhibit A to this report is an exhibit identifying the lake shorelines that were inspected, with color-coded identification to delineate shorelines that were satisfactory (green), shorelines with “minor erosion” (yellow) and shorelines with “extensive erosion” (red). The exhibit also identifies reference numbers for photographs which are included as Exhibit B to this report. Please note that in general,   only photos of problem areas are included within this report and the photos were taken during the dry season.

SUMMARY
It is also recommended that continuing inspections of The Arborwood SWMS be performed to monitor the condition of the SWMS. A SWMS of this nature requires continuing maintenance to ensure functionality of the system, and inspections by a registered professional engineer are integral to identify problem areas and/or confirm that the system is functioning adequately.
