NEW JERSEY 08736 TELEPHONE (732) 292-1805 FAOEIMILE (732) 292-1807 Re: Birch Court Road - Asphalt cracking, water seepage and staining, and drainage Dear Mr. Melchiori: On November 20, 2002 you responded to my September 13, 2002 letter of concerns about my Lot #54. In December 2002 you and the City of Sebastian met and planned a course action to resolve the standing water behind my lot. That work has been completed and so far water does drain away and the swampy lake has disappeared. The correction of that problem was as a result of every one working together to resolve what was a common problem. It is now time to address the second issue in my September 13, 2002 letter - the construction and condition of Birch Court. The problem with Birch Court is the same problem as Redwood Court with one additional and important problem - The water does not drain from the top of the cul-de-sac because the top of the cul-de-sac is lower then the sides of the cul-de-sac. Therefore water sets in front of my house on the cul -d -sac. I have a copy of your November 7, 2002 to the residents of Collier Club Homeowners Association with reference to "Pavement Staining, High Water Table" and I offer the following comments: You are correct in stating that "heavy construction equipment used during the house construction ... caused pumping" and cracking of the pavement. This, though, is simply an acknowledgment that a. The roadway was not constructed according to code (see Jonathan Kedith's letter report dated January 30, 2002) in the amount of ashpalt put down but also in the preparation of the sub grade. b. The situation on Redwood Court, as well as Birch Court, should have been foreseen by the developer. Your engineers, Fraser Engineering and Testing, Inc, reported that there was a very shallow hardpan in the Redwood and Birch Courts area. These areas were known to swampy before your construction ofthe road. Therefore it was known MERRITT LANE, III CERTIFIED PUBLIC ACCOUNTANT On Site Management Group September 2, 2003 Page 2 that the water simply did not drain and the ground was wet most the time - before any irrigation systems. 2. Your statement that "the roadways within the community are the maintenance responsibility of the Homeowners Association" is not quite correct. Before the roadways become the responsibility of the Homeowners Association, the common area including the roadways must be accepted from the developer by a homeowner's association that is not controlled by the sponsor/developer. The structural integity of the roadway, eventhough the last construction was completed over a year ago, is still deteriorating, soft depressions are forming and, of course, the drainage is simply wrong. The residents of Birch Court will be working with the City of Sebastian and hopefully you to correct the problems on Birch Court. Re ectfully v Merritt Lane, III 583 Birch Court, Sebastian, FL 32958 772-581-9253 cc: David Fisher, P.E. City of Sebastian, Engineer Trac Hass, City of Sebastian, Director of Growth Management Payor' City of Sebastian November 7, 2002 Collier Club Homeowners Association: RE: Pavement Staining, High Water Table Dear Residents: We have investigated the reasons for the reddish stain on the pavement as well as the unusually high water table in portions of the Collier Club Community. Both of these problems are primarily a result of a layer of "hard pan" approximately four foot below the surface. Hardpan is a dense layer of soil that prevents water from percolating resulting in a saturated soil column between the hard pan and the surface. This hardpan layer was not fractured during utility construction on the cul-de-sacs as it probably was on Collier Lake Circle because the utilities constructed in this area were shallow, above the hardpan layer. The reddish stain is a result of the ground water taking on the color of the hardpan material. In addition, heavy equipment used during the house construction, cement trucks, sand trucks etc. can cause "pumping" of the water bring the staining to the surface. With construction completed in Phase I this would no longer be an issue. Another factor contributing to the high water table may be the excessive irrigation done by some of the residents in the community. We brought this to the attention of the homeowners at the annual meeting and was brought to our attention again by the Sebastian Code Enforcement Officer this summer. Careful monitoring of your irrigation system would help control the constant "sogginess" of your individual lawns. At this time we have been given no clear-cut solution that would correct the problem. With the construction of Phase I completed and the vast majority of the heavy construction traffic completed we are hopeful the structural integrity of the pavement will not deteriorate. However, re -surfacing the pavement at this time may only be a temporary fix and the problem could reoccur. Seal coating, covering the pavement with a thin layer of tar, would make the pavement look better but provide no structural value. Therefore we feel the prudent thing to do at this time is to monitor the situation to see if the condition of the pavement stabilizes. Once this has been established the proper corrective action could be better determined. Should the individual homeowners wish to undertake a corrective action at this time we would ask that they coordinate this effort through Robin Jones the property manager.

Keith, P.E. 1) The streets within Collier Club are and shall remain private. They are the perpetual maintenance responsibility of the Homeowners Association. The city will not assume any responsibility for the roadways as long as the community is gated. There is no plan to eliminate the gates. 2) The City approved the typical roadway section. This is the same pavement section we have used in various other communities we have developed including Stonebridge, Cypress Lake, Pointe West and Arbor Trace. 3) To my knowledge no maintenance agreement with city exists. Because the streets are private there is language on the plat stating the maintenance obligation for the streets lies with the POA and the city shall have no maintenance obligation whatsoever. 4) We contracted with Fraser Engineering, now A&M Engineering, to do the testing on the utility back fill and roadway construction. They worked under the direction of the project engineer Masteller and Moler, Inc. as well as used there own judgment and industry standards regarding the testing. We had no input as to the location of the tests or the number of test taken. In our opinion neither we as the developer, nor any of the consultants or contactors working on the project, purposely did anything to hide or create a potential problem. The staining that has occurred in the area did not surface until after the adjacent property was filled and homes constructed. The situation on Redwood Court was unforeseen by all involved. You indicated in your letter dated February 1, 2002 that you expected us to proceed with Mr. Keith's recommendation of replacing the roadway with a geotextile fabric and 6" of reinforced concrete. We are not willing to proceed with a repair of that magnitude because 1) the initial construction was done in accordance with the approved plans and specification and 2) the "staining" of the roadway was not a result of any deficiency in materials or workmanship. Since the roadways within the community are the maintenance responsibility of the Homeowners Association, they would be the responsible party for correcting a problem. If the association wishes to proceed with Mr. Keith's recommendation and fund it with a special assessment of its members it would be up to them. .

You and Mr. Mechling both responded by telephone to me. Over the summer, at a meeting of all Collier Club homeowners, two Redwood Ct. members were assured by Mr. Mechling that our road would be properly resurfaced when other resurfacing was done in Collier Club. I am aware that you sent documents to Jonathan W. Keith, our civil engineer and we have also researched documents from the City of Sebastian re: our road construction. Enclosed, please find Mr. Keith's letter tome dated January 30, 2002. We again expect remedial action as stated on Page 3, item letter A. Please contact Jonathan W. Keith at (954) 489-9801 to set up a meeting to resolve this problem and furnish us with a copy of the Road Maintenance Agreement. Mr. Mechling said that Mr. Ed Donner would contact Mr. John Carroll (581-2778) re: the beautification of the park at the corner of Redwood Court. This has not been done to this date. We look forward to working together to resolve this matter of our road and park in a satisfactory fashion. Obviously we are most anxious to get this done quickly and efficiently.

Specifically, I have identified two areas of concern: a. The soil density reports slow that the lest locations for both the subbase old the road base (two different layers) were taken at the exact same locations within Redwood Circle (Palmetto Court). usually as tlac testing eoupauv or Engineer of Record it is desirable to nraimrtain randomness in the testing locations In this way there is a reduced imssibility that the roadway Corti actor will concentrate efforts to properly compact the roadway bases nr only certain locations The absence of random testing locations,_ although not conclusive does indleale a peed for additional teshpg_10 confirm uniformity in the dcusificalion of the roadway bases throughout the street from end to eird. b. Appendix "ll" of [lie Soils Report prepared by mouser Engineering and'I'esling, Inc. provides information rcgiudiog dic"pereliod" water table and "apparnat" water table within the developme t. 'I'lre "pereled" water table is above ale "apparcul" water table and is usually created by an impervious layer of ecnentcd sand (hardpan) prolibiting the water to percolate down to die "apparent" water table. According to the boring locations, hardpan, was encountered within the lake near Redwood Circle. 'fle existence of a pre-existing wetland near this location fwther suggests that the hardpan layer could lave extended into the Redwood Circle area. As 1 staled in nry October 231' letter, 1 belicvc that a "perched" water table exists witbm (lie Redwood Cim cle area whiel► has contributed to the saturation of the r oadwav bases within Redwood Cir cic 'Phe saturatlou of the bases (especially during the rainy seasmi) has contributed, in part. to the deeradatiun of the structural capacity of the existing roadway.

Page 2 of 3 necessary to Irrovidc pro )cr dr party lu suunurt iraflic lu rJs and it appears that the n9pllalt amid read base has failed in several locations. In conclusion, based upon the additional information provided by the City and OuSitc, 1 have 1101 wavered from lily earlier iccommeudatiuns for corrective actions to repair Redwood Circle. As 1 earlier slated: A. d'hc existing asphalt coarse cannot be sealed with all additional layer of asphalt because the ulnlerlyiug sub -base and base coarses arc not providing adetluate support for tine existing asphalt layer mmcl) less any new layer. Theretimq the application of a layer of new asphalt will only provide n shoe t term aesthetic remedy to the problem_ In time, tic new layer will also crack due to a lack of structural support within the sub -base and base coarses. );. The rout of the problem appears to be the condition of tine underlying sub -base mid base coarses. If these coarses are saturated, contain plastics or a combination thereof, tie uluisture must be clinninated penuatlenlly and these coarses re-cumpacted to optinmm, design densities prior to applying a new asphalt coarse. This remedial action is not practical because elle proximity of the apparent. water table will only re -saturate die coarses as is the existing case. C. Au alternate action would be to excavate and remove the existing deteriorated asphalt will base coarse layers within tine entire roadway and install a rigid layer of pavement consisting of at least G" ofroinforced concrete over a geotextilc fabric and stabilized sub -base. This will si( nilicanlly reduce cracking and the deterioration of the roadway. D. la ally case, I am prepared to nave forward in retaining helping your continency retain the services of a Oeoteclutical Engineer to conduct asoils and structural analysis of the roadway to verify illy findings and provide a recommendation to correct the problem. As stated py of the Roadway Maintenance Agreement from the above, I suggest that you obtain a uu City Attorney's office and review the docunent with your attorney and I would appreciate your fowarding a copy of the Agreement to are, as well.

The following represents our field observations and suggested remedial work required to correct the problem: A. Observations: The asphalt coarse within Redwood Court from Collier Lake Circle east to the cul- de-sac is cracked in numerous locations and water was seeping out of several cracks, especially at the asphalt edges and at the drainage inlet locations. This cracking is indicative of the structural failure of the underlying sub -base and base coarses. Additionally, moisture between the base coarse and asphalt coarse has reduced the adhesion between the two materials_thus creating additional damage to the asphalt. 2. The Redwood Court area of the development abuts a wetland area to the east. It appears that the depth from the asphalt surface to the apparent water table within the area is less than three feet (3'). 3. There may also be plastic (clay or marl) characteristics of the soil beneath and within the sub base and base sections which do not allow the water to percolate downward to the water table. 4. It appears that the soils utilized for sub -base construction under the asphalt and base coarse are fine grained and may subject to capillary rise. Because the water table is very close to the sub -base coarse, the water actually "wicks" up into the sub -base coarse and saturates this soil layer. The saturated soil does not have the optimum moisture content necessary to provide proper density to support traffic loads. 5. Furthermore, the coloration of the seepage from cracks within the asphalt matches the color ofthe base coarse materials utilized within the development which indicates Page 1 of 3 that the base coarse is also saturated. In many locations, foot and wheel loading adjacent to the cracks created "pumping" of the water upward through the cracks onto the surface of the asphalt. This indicates that the base coarse is fully saturated and will not support wheel loading as would soil having an optimum moisture content of approximately 6% to 10%. 6. Due to the base coarse and sub -base coarse being saturated, the existing roadway will not provide adequate support for vehicles, especially larger vehicles such as construction equipment and moving trucks. The asphalt coarse has cracked due to deflections within the base coarses. We believe that much of the damage to the roadway occurred during the construction of the adjacent homes when heavy construction equipment, concrete trucks and dump trucks frequently utilized the roadway. We believe that it is fair to say that the original roadway design section for Redwood Court did not contemplate soil saturation or the use of plastic soils in the construction of the roadway. B. Remedial Actions: 1. The existing asphalt coarse cannot be sealed with an additional layer of asphalt because the underlying sub -base and base coarses are not providing adequate support for the existing asphalt layer much less any new layer. Therefore, the application of a layer of new asphalt will only provide a short term aesthetic remedy to the problem. In time, the new layer will also crack due to a lack of structural support within the sub -base and base coarses. 2. The root of the problem appears to be the condition of the underlying sub -base and base coarses. Iftlnese coarses are saturated, contain plastics or a combination thereof, the moisture must be eliminated permanently and these coarses re -compacted to optimum design densities prior to applying a new asphalt coarse. This remedial action is not practical because the proximity of the apparent water table will only re - saturate the coarses as is the existing case. 3. An alternate actionwouldbe to excavate andremove the existing deteriorated asphalt and base coarse layers within the entire roadway and install a rigid layer of pavement consisting of at least 6" of reinforced concrete over a geotextile fabric and stabilized sub -base. This will significantly reduce cracking and the deterioration of the roadway. 4_ In any case, we are prepared to move forward in retaining a Geotechnical Engineer to conduct a soil and structural analysis of the roadway to verify our findings and provide a recommendation to correct the problem. Additionally, we suggest that you obtain copies of the following documents from the City of Sebastian Engineering Department (all of which should be public information): a. Copies of all applicable permits issued to the Developer and/or Road KEITH & BALLBk INC. Page 2 of 3 -1 Construction Contractor for Redwood Court; b. Approved construction drawings for the road including approved pavement sections and specifications, plan and profile sheets and construction notes; C. Record as -built drawings of the roadway; d. The Record Engineer's Certification of the roadway; e. Density test reports for the sub -base and base coarses; f. Proctor test reports of the soils utilized within the roadway; g. Inspection reports prepared by both City and record Engineer personnel; Please provide a copy of this information to our office for our review and analysis. If the Developer's representative or Engineer wishes to meet with a representative from our firm and the City of Sebastian Engineering Department at the site, we will make ourselves available. If you have any questions or require any additional information, please do not hesitate to call our office. Sincerely, KEITH & BALLBE, INC. an W.
