Mr. Anderson said the infrastructure has been put in place and they have the one year maintenance bond on the infrastructure. Ms. Doyle asked if all the deficiencies noted in the letter had been addressed. Mr. Boswell said the only thing the bond doesn't cover are the swales and he has a meeting scheduled with the contractor tomorrow morning to make sure they are put in the right place. Ms. Williams asked if the engineer had given a letter to the city. Mr. Anderson said when the meeting took place the engineer' s concerns were the two swales and they included them in the bond.

Mr. Wolff moved to approve, Ms. Doyle seconded, and the vote was unanimous. Ms. Schleicher said they have had Engineers look at it and they've gotten a potential budget cost for paving Solomon and crush and run. She said if they are going to pave Solomon they do not have enough money in this years budget so it need to be addressed in next years budget if that is the decision. She said they are going to put up guard rails at the deep ditch. She said they Page 9 of 10 would like to look at making it one way going East. She said it would cut down on the non local traffic. She said the people living on Solomon would have a right turn to leave the Island and a light to make the Left turn at Campbell to go back home. She said they need to get input from the neighbors before any significant cost is determined for improving the street. Ms. Schleicher said regarding the Savannah Restoration Contract for the Guard House. She said the change order reflects the taking out of the Fire Suppression System.

Statesboro, GA 30458 CITY OF TYBEE ISLAND RE: Van Horne Avenue Subdivision Dear Sir/Madam: CITY MANAGER Diane Schleicher CLERK OF COUNCIL Vivian Woods CITY ATTORNEY Edward M. Hughes 1. �p Chatham County property records indicate that you are the current owner of the property known as Van Home Avenue Subdivision ( #16 Van Home) on Tybee Island, Georgia. The Parcel Identification Number for this property is 4- 0003 -09 -034. To date, this property has outstanding drainage issues that need to be clarified in order to have the permit for this property finalized. The issue in question is whether or not the drainage swales and utilities have been entirely located within the dedicated easements for this property. An accurate as -built drawing would identify both of these and can be obtained from the project engineer. The engineer that originally worked on this project was Mr. Mark Boswell and he can be reached at 912 - 897 -6932. The City of Tybee Island appreciates your cooperation in getting this matter taken care of before August 1, 2010 so that we may move forward and allow closure on this project for future use.

The project site presently contains several residential type structures which are to be demolished. The proposed project is to be cleared of trees and stumps required for construction of a new four lot subdivision. The new project will have grading, water and sewer. The total site is 1.31 acres with the estimated disturbed area to be 0.75 acres. The soils in this area have been classified by the Chatham County Soil Survey Map as being Cue (Chipley -Urban Land Complex). The soils on this site have not been field verified. ANALYSIS METHOD The Rational method was utilized for the analysis of the pre - development and post - development runoff for this site. Hydroflow Hydrographs software was utilized to perform these analyses and for the purpose of sizing pipes, inlets, ditches and detention. The analysis was performed utilizing the following data: DR4/NAGE"AREA PRE - DEVELOPMENT RUN -OFF COEFFICIENT WEIGHTED AVERAGE - 0.35 POST - DEVELOPMENT RUN -OFF COEFFICIENT WEIGHTED AVERAGE = 0.48 IDF CURVES = SAVANNAH HYDROGRAPH GENERATION METHOD = PRE - DEVELOPMENT SLOPE = 2% POST DEVELOPMENT SLOPE = 2% TIME OF CONCENTRATION PRE - DEVELOPMENT = 10 MINUTES TIME OF CONCENTRATION POST - DEVELOPMENT = 10 MINUTES RATIONAL The proposed project is to be cleared of necessary trees and stumps to make way for the new structure. The resulting increased runoff, which is encountered due to new impervious area is displayed below: RUN -OFF RATE (25 YEAR STORM) PRE- DEVELOPMENT RUN -OFF = 3.02CFS POST - DEVELOPMENT RUN -OFF = 3.61 CFS TOTAL INCREASE IN RUN -OFF = 0.59 CFS Storm water will be directed by existing conditions but will also be routed by gutters and downspouts installed on new residential structures and new swales.
