Galligan _ J U N Town of South Windsor, Town Hall ,. MOM 1540 Sullivan Avenues V South Windsor, Ct. 06074 And: Jerry C. Iazzetta, Town Engineer and to whom it may concern. Re: Forest Village Subdivision-Punch List dated May 26-th 1998. Dear Mr..Galligan and Mr. Iazzetta: Concerning our meeting on the date of May 27-th, 1998, 2:30 p.m., at the request of Jerry C. Iazzetta, Town Engineer, we send our point of view for your consideration. You also gave a Punch List dated May 26-th, 1998 which is addressed not to us, but to Michael J. Gantick, Director of Public Works. On my request I and my two engineer experts reviewed originally approved subdivision plans, road and utility as-built plans and various communications. A site inspection was also completed on May 1-st, 1997 and May. 19th, 1997. Plans and documents reviewed are in Schedule A which is attached to the report. Our goal in reviewing these documents was to: 1. Determine the subdivision plans as originally approved and/or modified by South Windsor regulatory commission, 2. To check Punch List prepared by the engineering department on April 15th, 1991 (ref. 10)with accurate representation of outstanding items in need of completion or correction. The second unsigned Punch List dated 9/13/96 with an attached Town of South Windsor Bond Estimate Form dated 9/4/96 was also reviewed. The 10 items listed in the Punch list, although identified to be Forest Village Subdivision, was not signed by a responsible representative of the Town of South Windsor and therefore not addressed to A.G. Builders, Inc. Memorandum dated May 26th, 1998 was not addressed to A.G. Builders, Inc., but only to Mr. Michael Gantick, Director of Public Works. We have three punch lists and are supposed to have only one. Please, address one final Punch List to us so that we can discuss all items. RESPONSE AND/OR FINDINGS TO THE MEMORANDUM dated May 26th, 1998 Item numbers below correspond to the item numbers in Check List prepared by the engineering department, two our experts, concerning: 1. Detension basin outfall erosion problem must be corrected: 1 Concerning the drainage outfall at Gorski Drive, South Windsor, Ct, according to Town of South Windsor request and case in Superior Court at 69 Brooklyn Street, Rockville, Ct, No. DN CV960060622, Town of South Windsor vs. Alexander Gorski. The court dismissed and closed out the case for ever and our attorney David L. Gussak obtained on date 6/27/97 these informations: Please, be advised that this court entered a Judgment of Dismissal, in the above entitled action on date 6/20/1997 for failure to prosecute said action with reasonable diligence (PB 251). See enclosures. Concerning the inspection of drainage at Gorski Drive, we have a report from one of our experts,which says: To whom it may concern, According to your Mr. Gorski request, on the 8th of October, 1996, I inspected the outfall of the storm sewerage system off Gorski Drive. Mr. Gorski showed me the outfall of the sewer to the east of Gorski Drive, between lots 17 and 18. The flared outlet was discharging into a sedimentation basin. This basin had a few inches of sandy settlement in it. The flow from the sedimentation basin was discharging through another pipe into a small brook located southerly from this basin. The rate of discharging was approximately 150 ft downstream from the detention basin. We did not notice any sign of erosion either in the sedimentation basin nor in the brook - Bancroft Brook. Vegetation and bamboo was growing in the channel, which provides good protection for potential erosion problems. Since this summer we had extraordinarily high precipitation, we assume that if erosion caused a problem,it would have manifested itself "I have not known Mr. Gorski in the past and have not been involved with any part of his work." We, A.G. Builders, Inc. want a correction concerning this occusation and written response after a visual inspection. We made a request that Ident Street was attached to our detention basin, and is more water coming to our basin, which is good only for 43 acres. Our subdivision has only 43 acres of land. Subcontractor bond for Town of South Windsor was released to him after finished work and five year guarantee did not show any erosion in the detention pond. We still don't have any erosion on the basis of experes opinion. This means if subcontractor bond was released, Town of South Windsor and Bank accepted his work, and paid for after inspection made by a bank inspector. ITEM No. 2: Binder pavement on Bancroft must be removed and replaced prior to placing finish course of paving. We agree with Mr. Iazzetta that the binder pavement must be removed and replaced prior to placing finish course of paving. 2 ITEM No. 3: Approximately 450 linear feet of sidewalk must be removed and installed in accordance with Town Standards. We have inspected the sidewalks within this subdivision. These sidewalks have been in place for 10 plus years and are in excellent condition except of 100 feet, which are supposed to be replaced. A guarantee for sidewalks is only for 5 years and in the past 10 years we still have good sidewalks. This subdivision is located in an area which is underlain with sandy soils. These soils make an excellent base for roads and sidewalks. This is sustained by a letter (ref 13) from the Director of Public Works indicating that the native sand is approved as a sub base material. Regarding uncompleted sidewalks, it is not unusual to install sidewalks as individual lots are developed to prevent damage to walks. Accordingly, sidewalks which remain to be installed should be bonded on a per foot basis. As a lot is developed and the sidewalk completed in accordance with approved plans, a portion of the bond could be released. Bond to the Town of South Windsor concerning installation of the sidewalk was returned to the subcontractor, because his work was accepted. The bank inspector also accepted his work and paid him on the basis of a 5-year guarantee. Within these 5 years we did not have any problems with sidewalk, except vandalism on approximately 100 feet,which must be replaced. ITEM No. 4: Approximately 2,500 linear feet of sidewalk still needs to be installed. We agree that approximately 2,500 linear feet of sidewalk still needs to be installed according to Town Standards after finishing of construction of 17 houses which will be built as soon as possible. ITEM No. 5: Strong Road needs to be widened (about 20 feet long), a drainage structure installed and about 280 feet of curbing installed. The original subdivision plans (ref 1), specifically drawing 5 of 13, state that Strong Road shall be widened 5 feet from existing edge of pavement along entire property line. The approved plan and profile drawings (ref 2), specifically drawing 8 of 13, shows Strong Road was originally 18-19 feet wide. Measurements from the existing northerly road edge indicate that the widening provided a road width of 24-25 feet. The widening need to end prior to the centerline on Bancroft Brook where the Forest Village Subdivision property line occurs. An appropriate taper of approximately 100 feet(20:1),prior to this point,was measured in the field. 3 The imposition by Mr. Iazzetta of additional conditions, ie. drainage structure, curbing and additional road widening is beyond what was originally approved by the Planning & Zoning Commission. Our obligation is to comply with approved plans which we did. ITEM No. 6: Structures between lots 7 and 8 need to have grading adjusted. We agree for grading adjusted between lots 7 and 8. ITEM No. 7: Easements are required across lots 22 and 23 and additional easement required between lots 7 and 8. The originally approved subdivision plans(ref. 1), specifically drawing 5 of 13, depict a 20 foot easement centered on the common property lime o lots 7 & 8, and located along the northerly line of lot 40. The sanitary sewer line was shown centered on this easement. We indicated that this sanitary line was installed favoring the northerly edge of this easement to accommodate a storm sewer pipe which was to be installed by the Town of South Windsor. A plan prepared by the Town of South Windsor Engineering Department (ref 7) clearly shows a design for installation of this storm sewer.. . A review of the As-built Plan(ref. 8), specifically Sheet 2 of 5, shows these improvements are within the originally granted easement area. I do not see the need for an additional easement area, especially considering that the Town of South Windsor intended to install the additional storm sewer pipe through this easement. Lot No. 7 was sold on the date October 26th, 1998 and has a certificate for occupancy. As-built drawing (ref. 8), specifically on Sheet 1 of 5, indicated that the storm pipe was installed across the easterly portion of Lots 22 and 23. An easement was granted and recorded with the South Windsor Town Clerk's Office in Vohune 807, Page 56 (ref. 12). ITEM No. 8: Trench patches on Gorski Drive must be repaired or replaced. We did not find a reference to trench patches in Mr. Iazzetta's letter dated May 26th, 1998 (ref 14). We assume this reference is to Bancroft Road. Trench patches will be fixed when a final 1" course is placed. ITEM No. 9: Pavement on Gorski drive at the cul-de-sac needs to be extended to the back of catch basins. 4 We agree that pavement on Gorski drive at the cul-de-sac needs to be extended to the back of catch basins. ITEM No. 10: Entire ROW area on Bancroft need to be graded, etc. in accordance with Town Standards. We agree that entire ROW area on Bancroft Lane needs to be graded, etc. in accordance with Town Standards after we finish the construction of 17 houses. ITEM No. 11: Eleven(11) catch basin tops need to be replaced. In our opinion eleven (11) catch basin tops look like brand new and we don't see any reason for replacing them Please, send us a written response with a reason of replacing them ITEM No. 12: Pipes in catch basins need to be cut flush and mortared correctly. We agree that pipes in catch basins should be cut flush and mortared correctly. ITEM No. 13: Forty-five(45)monuments need to be replaced. Forty-five (45) monuments were installed by Alford Associates, Inc. Engineering for the entire subdivision. According to blueprint specification for forty (40) lots and approved by Planning &Zoning Commission. Please, send us a written response with a reason why they are to be removed as soon as possible. ITEM No. 14: Split rail fence for the Open Space entrance needs to be installed(about 100 feet). We don't have conditions in subdivision approval for installation of 100 feet of split rail fence for the Open Space. In our approved subdivision we have tree buffer zone which is already installed and the work was approved by Town Engineering Department. ITEM No. 15: Open Space entrance on Gorski Drive must be cleared. 5 We agree that Open Space entrance on Gorski Drive must be cleared. ITEM No. 16: Pedestrian ramps at Gorski and Bancroft must be replaced. There is a 4" drop to the pavement. We agree that pedestrian ramps at Gorski and Bancroft must be replaced. ITEM No. 17: As-built drawings are required. As-built drawings are done in 80% and remaining 20% will be done after construction of 17 houses. ITEM No. 18: There were about 30+/- Eastern Pines to be installed as per P&Z approval condition 1F. Less than half exist today. The approved subdivision plans, specifically Drawing 5 of 13, indicate that 2" caliper white pines shall be planted 15 feet on center, lots.1 through 4. We concur with Mr. Iazzetta that plantings along a portion of the rear lot line of lot 3 &the entire rear lot line of lot 4 are lacking. We would like to explain that trees were not planted along these rear lines because these areas are wooded. We concur that the wooded nature of the lots in this area will make the pines an understory planting and therefore not a very effective buffer. Since the additional punch list dated 9/3/1996 was not signed by a responsible individual from the Town of South Windsor to Alexander Gorski, president A.G. Builders, Inc., we request that the current checklist of outstanding items be prepared again for my review as an addressee. We expect a response from you as soon as possible.

On April 6, 1998, 1 was in the Superior Court in Rockville. At that time, at my request, the Clerk of the Court rechecked the file and confirmed to me that the case on the attached notice has been dismissed, that there was no move to reopen it within the four month period, and that the file, therefore, has been closed out. I trust this will enable you to proceed with the other aspects of this situation without further concern regarding that particular matter.

Folger, Zoning/Wetlands Enforcement Officer FROM: Jerry C. Iazzetta, Town Engineer Date: June 16, 1999 Re: Gorski — Detention Basin Repair We have reviewed the plans dated5/24/99 for the proposed repairs to the detention basin in the Forest Village Subdivision and have the following comments: 1. A gravel access road is required in accordance with the Public Improvement Specifications. The roadway should be built to enable access for maintenance of the outlet structure and rip rap swale.

Per a discussion with Jerry lemetta, I have added the gravel access roads and an as-built survey to the estimate. I have also increased the unit cost for some items based on apparent local costs as reflected in the town's bond estimate form. I believe the total figure is quite conservative on the high side. It does not include the town's 26% contingency figure which is extremely conservative, but I guess reflects the town's costs if they,had to bid the project as opposed'to a private developer. While the gravel access roads have been added to the cost estimate, as you know this office does not believe these gravel roads are appropriate in this specific case. It is unlikely that any maintenance will be required for the detention pond or outfall. The most likely maintenance will be the removal of small debris from around the outlet control structure. This can be done by hand or with small equipment. The area of the existing drainage easement and the open space access appear to have stable soils that should not be difficult to drive over with small equipment for routine maintenance which can be done during dry weather. It is possible that the contractor will choose to install some gravel along his construction access route. This gravel can be left in place, However, it would not appear to be in the best interests of the IVWVCC to encourage access or heavy maintenance in this,6rea. We have therefor not shown either of the gravel access roads on the plan. JUL 26 '99 11:00AM F.A.

Gussak, Esquire of Reiner, Reiner& Bendett, P.C.) who shall hold said proceeds until such time as bills or invoices for the work described on Exhibit D shall be submitted at which time said monies may be disbursed towards the satisfaction of said bills or invoices; net proceeds as described herein shall be the sales price, less any bond escrow payment as described herein and less any sales expenses, such as commissions, legal fees, conveyance taxes and less any adjustments required for payment of real estate taxes. Once three lots are sold this proviso shall expire. 14. Owner/Developer and the Town agree that either the Owner/Developer or any person, firm or corporation which shall purchase any lot or lots from the Owner/Developer shall be entitled to obtain a building permit or permits for each such lot from the Town provided the Owner/Developer or the entity who shall have purchased said lot from the Owner/Developer shall comply with and meet all requirements of the Town for the procuring of a building permit, and further provided that the cash escrow deposit for each of such lots for which a building permit is requested shall have been 10 r VOL. 1112 PAGE Ad made in compliance with the provisions of paragraphs 10, 11 and 12 herein. At the discretion of the Town and as a condition for the issuance of Building Permits, the Town may impose a requirement that for the first five (5) lots released from the real estate bond, the escrow deposit shall be the sum of Thirty Thousand ($30,000.00) Dollars for each of such lots. After five (5) lots have been released, the sixth lot and each subsequent lot, the escrow deposit shall be the sum of Twenty Thousand ($20,000.00) Dollars. 15. The Owner/Developer and the Town further agree that the Owner/Developer or any person, firm or corporation which shall have purchased a lot or lots from the Owner/Developer may, upon completion of the improvements to any lot pursuant to a building permit obtained in accordance with paragraph 13 herein, obtain a Certificate of Occupancy for such improvement, provided such improvement shall have been constructed in conformance to the building, health and safety codes pertaining to such structure, and shall have passed such requisite inspection procedures required by the building, health and safety officials of the Town. 16. The parties hereto agree that upon completion by the Owner/Developer of items as described in Exhibit D, the Owner/Developer shall be entitled to a reduction of the bond as follows: A. If the bond is solely and exclusively a cash bond, the sum of cash being held may be reduced by the amount allocated 11 voL. 1112 PAGE 2 9 4 in Exhibit D for those items completed to the satisfaction of the Town. b. If said bond shall consist solely of real estate, or of both cash and real estate, said real estate bond may be reduced by one (1) lot for each Thirty Thousand ($30,000.00) Dollars of value for the items completed to the satisfaction of the Town as allocated in Exhibit D. The completion of each of the items in said Schedule D must be confirmed in writing by the designated officials who shall be responsible for the inspection of such items to permit the bond reductions set forth herein. Notwithstanding any reduction in the bond permitted under this section, the Owner/Developer shall still be bound by the escrow provisions of paragraphs 10, 11 and 12, except that if the completion of items described in Exhibit D have been confirmed in writing as provided herein, the cash escrow shall not need to be greater than the amount allocated to the remaining items in Exhibit D. 17. Upon completion of all items in Exhibit D, or upon completion of all said items, excluding any item whose completion date shall have been deferred by mutual agreement of the parties hereto, the Owner/Developer shall be entitled to a reduction of the bond to a sum not to exceed Thirty Thousand ($30,000.00) Dollars, which bond shall be held for a period of one (1) year from the date upon which completion shall be confirmed in 12 PLO VOI. 2 PAGE 2 writing by the designated Town representative as provided in paragraph 15 herein. Upon the expiration of said year, the bond monies shall be released and any remaining lien shall be released. The mutual deferral of completion of any item in Exhibit D shall not extend the time for the bond reduction contemplated herein, except that if upon the expiration of one (1) year any item in Exhibit D remains incomplete,then a sum representing one hundred fifty (150%)percent of the completion cost of such incomplete item may be retained by the Town until such item shall be completed. The designation of an item in Exhibit D as being incomplete and the completion cost of such item shall be stated in writing to all parties by the designated representative of the Town, and such statement of in completion and statement of cost of completion shall be presumed by the parties hereto to be conclusive, unless the Owner/Developer can establish that either or both of such designations are made in bad faith, in which event the Owner/Developer may make demand for arbitration of such dispute in the manner hereinafter set forth. 18. The parties hereto, pursuant to the provisions of paragraph 9 herein, have agreed that Owner/Developer shall complete the items designated in Exhibit D in a period one hundred twenty (120) days unless the completion date for any item or items shall, by mutual agreement, be extended beyond said date. In the event the Owner/Developer shall fail to meet such completion date, then the Town shall be required to give notice of such default in completion. Such notice shall be in writing in the 13 voL. 1112 PAGE 296 manner and to the parties hereinafter set forth, and said notice shall state with specificity the particular item or items which it is claimed are incomplete, and the specific defect or defects it is claimed exist. Upon receipt of notice of default of completion,the Owner/Developer shall have a period of thirty (30) days from receipt of such notice to undertake such action as may be necessary to correct or complete the items depicted in such notice.

Upon the expiration of said year, the bond monies shall be released and any remaining lien shall be released. The mutual deferral of completion of any item in Exhibit D shall not extend the time for the bond reduction contemplated herein, except that if upon the expiration of one (1) year any item in Exhibit D remains incomplete, then a sum representing one hundred fifty (150%) percent of the completion cost of such incomplete item may be retained by the Town until such item shall be completed. The designation of an item in Exhibit D as being incomplete and the completion cost of such item shall be stated in writing to all parties by the designated representative of the Town, and such statement of in completion and statement of cost of completion shall be presumed by the parties hereto to be conclusive, unless the Owner/Developer can establish that either or both of such designations are made in bad faith. in which event the Owner/Developer may make demand for arbitration of such dispute in the manner hereinafter set forth. 18. The parties hereto, pursuant to the provisions of paragraph 9 herein, have agreed that Owner/Developer shall complete the items designated in Exhibit D in a period one hundred twenty (120) days unless the completion date for any item or items shall, by mutual agreement, be extended beyond said date.

Any change in building or construction codes which may occur subsequent to the date of this agreement which could change the requirements of completion of items set forth in Exhibit D, shall not constitute an enlargement or additional responsibility of the Owner/Developer and any failure of Owner/Developer to comply with such change or modification shall not constitute a default under this agreement, and shall not constitute grounds or basis for the Town to refuse to reduce or release the bond lien or bond monies. Completion by Owner/Developer of the items set forth in Exhibit D in conformance with construction, health and safety codes as they exist as of the date of this agreement, shall be presumptive and conclusive evidence that the Owner/Developer has complied with and fulfilled its obligations under this agreement. 19.

On December 9, 1999 Joseph Perna from the Town of South Windsor Engineering Department and I made a visual inspection of the completed erosion repair and stormwater conveyance upgrades at the detention basin outfall from the Forest Village Subdivision. In examining the site of construction, it appears that the construction of the outfall, outfall pipes, rip-rap channel, and grading were done according to the proposed plans approved by the South Windsor Inland Wetland Commission. I understand that an as-built plan is pending by the design engineer. The finished grades have been top soiled, seeded and adequately mulched to prevent the movement of top soil from the slopes during the winter months. An evaluation will be made in the spring as to the success of germination of the seeded areas. This area may have to be raked and re-seeded in the spring and the mulch reapplied to perform the final, permanent stabilization. An amount of$2500.00 will be held from the original performance bond until the site is completely stable.

There are numL-$1-O-ts p<atr_•hrt?d cuts (cross laterals) in this pavement. One had a weak corner and a piece Of pavement was removed. It was -3/4" thick. I't appears that all of there were patchr�d without sealing the edges. All these patches should be removed so the depth of the base can be determined and the pavement thicF.:ness can be determined. The new repair should be according to road specifications and the edges of each Patch should be Sealed. This road cannot be overlaid without removing the pavement around all manholes and catch basins, the thin shim used to protect them in winter will not allow for a i " - 1 1/2" overlay without leaving a bump at each structure. If paved as i s without leaving the bt-tmps, the pavement will be J.- thin and flake. .T. can only assume that Mr. Gorski wants to finish this to get a bond reduction. however, there are several lots not yet built , sidewalks and driveways do not exist --it these lots or at some others. There is no loam within the proposed street right-of-way, most of the Utilities stop at the Curb and do not extend to the street line. The patch has not been made when the storm sewer manhole was placed recently. I think it impractical to put the top on at this time.

I make reference to the numbered items in the above quoted Memorandum. 1. The originally approved subdivision plan on Drawing No. 11 shows the sanitary sewer manhole near the edge of road and not at the center of the said roadway. Also a letter written by Mr. Richard P. Martel, Town Engineer, dated December 19, 1986 indicates that "all of the necessary corrective work, relative to the sanitary sewers, has been completed to the Town's satisfaction. " I believe this text is self explanatory. The fact that the sewer is not at the center of the Right-of-Way represents no problem in my estimation. 2. a. Easements across lots 22 and 23 were granted to the Town of South Windsor and filed on Volume 807 Page 56. I examined a copy of this deed, which grants the Town a 15 ft. wide Right-of-Way. Also as-built drawings indicate on Sheet I that a storm sewer was installed through this easement. 2.b. A 20 ft easement was granted to the Town for the sanitary sewer. As the lot was sold and no longer owned by Mr. Gorski, he cannot change the existing easement. I was shown a plan prepared by the Town Engineering Department showing a storm sewer through this easement. For this reason Mr. Gorski constructed the sanitary sewer near the northerly easement line. As the sanitary sewer is well within the easement granted to the Town, I do not see any problem with this. 3. Concrete side walks. Concerning the missing sidewalks, Mr. Gorski informed me, that these will be completed after the houses are built. He believes that it is not prudent to build sidewalks until the house contractors are finished, because they damage the sidewalks wit their equipment. I believe this problem can be overcome by requiring bonds for the missing side-walks. 4. The existing side-walks are in good condition. The fact that after ten years of existence they show no cracks or any other sign of failure indicate good workmanship, and adequate foundation. AN EQUAL OPPORTUNITY EMPLOYER LENARD ENGINEERING, INC. Mr. Alexander Gorski August 12, 1997 Page 2 of 3 5. I inspected the row of trees along Lots 1 through 4 and I found them to-be mature adequate buffers. Denser planting would hinder the development of the trees. I think they provide an adequate barrier to the neighbors. 6. The widening of Strong Road along the frontage of the development was accomplished. The oiigiriai subdivision plan as sliown on Draw—Ing No. 5 of 13 indicates that the road shill be widened 5 ft. from the edge of pavement. Drawing No. 8 of 13 shows that Strong Road was 18 ft wide. The present width measures 25 ft. The widening was flared to the centerline of the culvert as this is the end of the property. Mr. Gorski cannot widen the road further westerly as he does not own this property. The widening must end at the property of Edward Sunderland. The quoted letter indicates requirements for a catch-basin replacing an end-wall, 280 ft of curbing and additional road widening. None of these items are shown on the original approved subdivision plan. 7. The standing water problem on Lots 3, 4 and 5 require grading. Grading of the individual lots should be accomplished by the contractors building on these respective lots. Grading is shown on the approved plan. The standing water is caused by a stockpile of earth material, which will be used during the development of the lots. All such work will be the responsibility of the contractor for each of the lots. 8. The approved subdivision plan did not require an easement at this location. Mr. Gorski is prepared to fulfill only those requirements which were stipulated in the approved plans. 9. Trenches indicated need patching. Mr. Gorski will correct these patches on Bancroft Road, when the final 1" course is placed.. 10. Grading around the drainage structures between lots 7 and 8. These are minor gradings, which will be completed. Minor quantities of fill is required around the sanitary sewer manhole. The manhole cover is presently 8-inches above the grade, which is a prudent practice, as it is desirable to keep surface runoff from entering the sanitary sewers. 11. Portions of Bancroft Lane must be completed according to the approved plans. Gorski Drive is completed in compliance with the plans. Also please see Note No. 3 above. 12. A second course of pavement is missing in parts of the development. This needs to be completed. 13. Sanitary manhole on lot 40 seems to be too high. In my opinion, it only needs fill around the cover. Should the manhole top be lowered, surface water may infiltrate the manhole, which is undesirable. See Note No. 9 above CMWfficelwinword 1WMNgm*j 8.12.97.doc LENARD ENGINEERING, INC. Mr.Alexander Gorski August 12, 1997 Page 3 of 3 14. I understand that this issue has been resolved. 15. As- built plans were prepared by Alford Associates. Inc. for the entire subdivision. The plans are dated June 4, 1990 and revised on June 11, 1990. These plans are Town records. Mr. Iazetta should clarify what is deficient on these plans. Pipes in eight catch basins need to be cut flush with the walls. The plans call for such cuts, and it should be accomplished. 16. Pedestrian ramps need to be reworked at the intersection of Bancroft Lane and Gorski Drive. A small lip to be installed at the time of laying the final course will resolve the problem. I hope the above observations will aid in resolving the remaining issues for the completion of this subdivision. I will be pleased to work with Mr. Gorski and the Town of South Windsor to get these issues resolved. Sincerely yours, LENARD ENGINEERING, INC. �6hn F.

You showed me the outfall of the sewer east of Gorski Drive between lots 17 and 18.The flared outlet was discharging into a sedimentation basin.This basin had a few inches of sandy settlement in it and also vegetation was growing in and around the basin..Indications were that it has not been cleaned this year or for years in the past. Flow from the sedimentation basin was discharging through another pipe into a small brook located southerly from this basin.The rate of discharge was approximately 5 gallons per minute. This brook was discharging into Bancroft Brook approximately 150 ft downstream from the detention basin. did not notice an.-',sign of crli5Lon either in the sed,'n.entat'on basin or,in the brook.Vegeta- tion was growing in the channel,which provides good protection for potential erosion problems.

Gorski 85 Ridge Crest Circle Wethersfield, CT 06109-1049 Re: Forest Village Subdivision South Windsor, CT Dear Mr. Gorski: At the request of Mr. Aleksander Gorski, I have reviewed the originally approved subdivision plans, supplemental plans, road and utility as-built plans, and various communications. A site inspection was also completed on May 1, 1997-and May 19, 1997. Plans and documents reviewed are itemized in Schedule A which is attached to this report. My goal in reviewing these documents was to (1) determine the subdivision plans as originally approved and/or modified by the South Windsor regulatory commissions were complied with, and(2)that the check lists prepared by the engineering department on April 15, 1991 (ref 10) were accurate representations of outstanding items in need of completion or correction. A second unsigned punch list dated 9/13/96 with-an attached Town of South Windsor Bond Estimate Form dated 9/4/96 was also reviewed. The 10 items listed in this punch list, although identified to be for the Forest Village Subdivision, was not signed by a responsible representative of the Town of South Windsor and therefore not addressed. Page 1 Mr. Aleksander K. Gorski May 20, 1997 Re: Forest Village Subdivision South Windsor, CT Response and/or findings to the April 15, 1991 memorandum. Item numbers below correspond to the item numbers in check list prepared by the engineering department. 1. On the originally approved subdivision plans (ref. 3), specifically on Drawing 11 of 13, the sanitary manhole at Ident Road is clearly shown short of the edge of road "ER" and not in the center of the roadway. It is unreasonable and inappropriate for Mr. Iazzetta to request this now. 2. Easements. a. As-built drawings (ref. 8), specifically on Sheet 1 of 5, indicated that the storm pipe was installed across the easterly portion of Lots 22 and 23. An easement was granted and recorded with the South Windsor Town Clerk's Office in Volume 807, Page 56 (ref. 12). b. The originally approved subdivision plans (ref. 1), specifically Drawing 5 of 13, depict a 20 foot easement centered on the common property line of lots 7 & 82 and located along the northerly line of lot 40. The sanitary sewer line was shown centered on this easement. Mr. Gorski has indicated to me that this sanitary line was installed favoring the northerly edge of this easement to accommodate a storm sewer pipe which was to be installed by the Town of South Windsor. A plan prepared by the Town of South Windsor Engineering Department (ref. 7) clearly shows a design for the installation of this storm sewer. A review of the As-built Plan (ref. 8), specifically Sheet 2 of 5, shows these improvements are within the originally granted easement area. I do not see the need for an additional easement area, especially considering that the Town of South Windsor intended to install the additional storm sewer pipe through this easement. 3. I have inspected the sidewalks within this subdivision. These sidewalks have been in place for 10 plus years and are in excellent condition. There is no evidence of crack or frost heave. Page 2 Mr. Aleksander K. Gorski May 20, 1997 Re:.Forest Village Subdivision South Windsor, CT This subdivision is located in an area which is underlain with sandy soils. These soils make an excellent base for roads and sidewalks. This is substantiated by a letter (ref. 13) from the Director of Public Works indicating that native sand is approved as a subbase material. Regarding uncompleted sidewalks, it is not unusual to install sidewalks as individual lots are developed to prevent damage to walks. Accordingly, sidewalks which remain to be installed should be bonded on a per foot basis. .As a lot is developed and the sidewalk completed in accordance with the approved plans, a portion of the bond could be released. 4. The approved subdivision plans (ref. 1), specifically Drawing s of 13 indicate that 2" caliper white pines shall be planted 15 feet on center, lots 1 thru 4. I concur with Mr. Iazzetta that plantings along a portion of the rear lot line of lot 3 & the entire rear lot line of lot 4 are lacking. Mr. Gorski explained that trees were not planted along these rear lines because these areas are wooded. I concur with Mr. Gorski's observation that the wooded nature of the lots in this area will make the pines an understory planting and therefore not a very effective buffer. 5. The original subdivision plans (ref .1), specifically Drawings 5 of 13, state that Strong Road shall be widened 5 feet from existing edge of pavement along entire property line.. The approved plan and profile drawings (ref. 2), specifically Drawing 8 of 13, show Strong Road was originally 18 - 19 feet wide. Measurements from the existing northerly road edge indicate that the widening provided a road width of 24 - 25 feet. The widening needed to end prior to the centerline of Bancroft Brook where the Forest Village Subdivision property line occurs. An appropriate taper of approximately 100 feet (20:1), prior to this point, was measured in the field. The imposition by Mr. Iazzetta of additional conditions, i.e. drainage structure, curbing and additional road widening is beyond what was originally approved by the Planning & Zoning Commission. Mr. Gorski's obligation is to comply with Page 3 Mr. Aleksander K. Gorski May 20, 1997 Re: Forest Village Subdivision South Windsor, CT approved plans which he did. 6. Presently there are no homes constructed on lots 3, 4 & 5. The approved subdivision plans (ref. 1), specifically Drawing 5 of 13, indicates that these lots will be regraded. A proposed Swale is shown starting on lot 3 and graded to drain water towards the headwall located along the southerly side of Strong Road. This grading can be accomplished with the development of these lots. Presently, a stockpile of material along the wood line on lot 3 is preventing water from draining towards the above mentioned culvert. 7. The request by Mr. Iazzetta for a "right to• drain" is again an imposition of conditions beyond those shown on the approved plans. Plans do not indicate a Town maintenance responsibility nor do they specify that a "right to drain" be granted. 8. I did not find a reference to trench patches in 1&. Iazzetta's letter dated May 19, 1989 (ref. 14). I assume this reference is to Bancroft Road. Trench patches will be fixed when a final V course is placed. 9. I inspected the-structures between lots 7 and 8 and found that the catch basin grate is set flush with the lawn. The sanitary sewer manhole is elevated above the ground level by approximately 8 inches. I would recommend that additional fill be placed around this structure to blend it with the surrounding grade. Generally it is better to have manhole higher to prevent surface waters from entering sanitary manhole. 10. I concur with Mr. Iazzetta that portions of the ROW are not graded per the "Typical Roadway -Section" shown on the approved subdivision plans (ref. 3), specifically Drawing 12 of 13. I believe that Gorski Drive, which is part of Phase I, has been graded per the typical roadway section. Portions of Bancroft Lane need to be completed. 11. Concur that the Class II finish course needs to be installed along Bancroft Lane.

Our scope of services includes evaluating appropriate modifications to the drainage system to improve the efficiency of the detention pond and reduce downstream erosion. We will also review proposals for restoration of already eroded downstream areas. We anticipate having a preliminary evaluation completed by mid January and an application package ready for submission to the town by the end of January. We will coordinate closely with town staff on the development of the recommended plan of action prior to the submission of an application. We understand that there is some concern shared by staff that there may be an immediate safety issue with the berm and outlet at the detention pond. One of our first tasks will be to meet with staff and Mr. Gorski at the site to determine if an interim repair is warranted until the permanent solution is implemented. Very truly yours, F. A.

Builders, Inc. 85 Ridge Crest Circle Wethersfield CT 06109 Re: Forest Village Subdivision Detention Pond Outfall Erosion Problem Our File: 98208 Dear Mr. Gorski: In accordance with our proposal dated November 30, 1998, we present this report of findings and recommendations related to drainage and erosion control problems associated with your existing detention pond at Gorski Drive in South Windsor. Our investigation included site visits, meetings with town officials, developing preliminary designs, and performing hydrologic analysis. Site Visits Engineers from our office visited the site to observe site conditions. In general, the basin appeared to be in good condition. Significant erosion was noted at the discharge point of the outlet to the detention basin. A 30-inch inlet drain was noted discharging into the detention basin and a 24-inch diameter pipe noted draining the basin. Meetings with town official We met with Mr. Jerry lazzetta, Town Engineer, and Mr. Jeff Folger, Zoning/Wetlands Enforcement Officer, both of the town of South Windsor, to discuss the problem, and obtained maps and data from town files. The town officials indicated that they were concerned with the extensive erosion at the outlet and downstream channel, the stability of eroded channel banks, and the stability of the berm separating the detention basin from the channel. Hydrologic analysis From available topographic maps and other data collected, we delineated the watershed and sub-catchment areas that discharge to the detention basin. We ran a hydrologic analysis of the watershed by computer model using generally acceptable Soil Conservation Service (SCS) methodology (TR-55 Method). The purpose of the analysis was to improve the efficiency of the detention pond and reduce downstream erosion. Our analysis indicates that by reconstructing the outlet structure to incorporate an orifice, peak flow of the discharge can be significantly reduced and the potential for downstream erosion lessened. Copies of the analysis are attached.

Seven copies of the preliminary design plans are attached. In addition to the plan sheet, attached is a preliminary profile of the proposed improvements and a typical section showing the pipe and the filling of the eroded stream. Also attached are the town's typical details for the outlet structure and the rip- rap swale. The design incorporates an outlet control structure, 115 feet of additional drain pipe, and 50 linear feet of rip rap lining. This design results in a reduction in peak flow discharge, conveys the flow to a less steep and more stable section of the channel, and incorporated energy dissipating and erosion control devices. We estimate that the construction cost of the proposed work is on the order of$20,000 - $30,000. Please note that our preliminary designs have been done on readily available topographic maps, which may not accurately depict current existing conditions. If you wish us to refine the design it will be necessary for us to complete field survey work. Results of our investigation and our recommendations are summarized below: • The Forest Village Subdivision consists of Gorski Drive and Bancroft Lane which both have storm drainage systems installed. Approximately 25 acres of land drains through this system to a detention pond to the west of Gorski Drive, behind lots 18 and 19. The detention pond has a 24" outlet which discharges to a small intermittent stream channel. • The stream into which the pond discharges shows signs of considerable erosion. The stream has cut through the overlying soils and into the underlying clays. In some areas the stream erosion has been enough to cause the adjacent banks to fail and slip down into the stream. Because of this, a number of trees have fallen or are leaning. • Since the inlet pipe to the basin is 30" and the outlet pipe is 24", even in large storms, very little of the detention capacity of the pond is being utilized and little reduction in peak flow is realized. Our preliminary plan shows the installation of an outlet control structure with an 8" orifice. This will reduce the peak flow for the 100 year storm to 3.1 cfs, with the elevation of the water in the basin reaching 55.83', well below the flow line of the footing drains and basements of the houses on Gorski Drive. • In order to remediate the existing erosion problem and minimize any future erosion, we recommend that you connect the existing outfall to a new 24" pipe that will follow the stream bed to a point approximately 115 feet below the existing discharge. The next 50' of the stream would be protected with stone rip-rap. Mr. Alexander Gorski January 27, 1999 Page 3 You have indicated that you met recently with the Town Engineer and the Wetland/Zoning Enforcement Officer and that they are in general agreement with the recommendations. Based on your comment we have changed the reinforced concrete pipe (RCP) to corregated polyethelene pipe (CPE). We understand that town staff concurred with this change. Copies of our findings and recommendations will be formally submitted to the Inland Wetlands and Watercourses Commission. If you or your contractor have any questions, feel free to call me to discuss them. Very truly yours, F. A. Hesketh &Associates, Inc. R®rJ. llman, P.E.

First, I have not met with Mr. Gorski nor have I reviewed this report with him. Secondly, I have not given approval to use corrugated polyethelane pipe (CPE) on this project. The comments I had when reviewing the plans that Mr. Jeff Folger, Wetlands Enforcement Officer forwarded to me were as follows: 1. Rip rap pad at discharge seems small — what is velocity and quantity of water at this point? 2. The detention basin outlet structure is not our current design — should use latest design. 3. Should use RCP not plastic pipe. I hope that this clarifies some of the items in your report concerning my comments/concurrence about the matter.

Folger Jerry Iazzetta Zoning/Wetland Officer Town Engineer Town of South Windsor Town of South Windsor Re: Review of the Gorski detention basin plan dated 1/11/99. I have reviewed the remeadiation plan for the erosion problem west of Gorski Dr. with the following comments: 1. Proposed rip-rap should extend to the limit of the eroded channel. 2. Temporary erosion controls should be located on the plan to prevent the migration of sediments during construction. 3. A subsurface drain installed below the floor of the basin along the southern edge that connects to the new outfall structure should be installed to prevent"bleeding" of water along the slope below the basin. See example of a similar installation enclosed. 4. A permanent vegetative stabilization plan should be included. The should include types, planting rates, and planting dates. I recommend that at least 30% of the seed type be a legume such as crown vetch, or flat pea. cc. Town Engineer Town Planner IWA/CC Forest Village Subdivision Detention Pond Outfall - Erosion Remediation Plan DESIGN CALCULATIONS RUNOFF TO DETENTION BASIN Based on available mapping and limited field observations the drainage area to the detention basin has been calculated at 25 acres. Under full development, it is estimated that the area will be 82.6% lawn, 13.0% impervious, and 4.4% wooded. Runoff from this drainage area enters the detention basin through an existing 30" RCP between lots 17 and 18 on the west side of Gorski Drive. The 100 year full development peak flow into the detention basin has been calculated at 63.1 cfs DETENTION BASIN AND OUTLET CONTROL STRUCTURE The existing detention basin covers an area of approximately .7 acres. The bottom elevation is about 52 and the top 62. Up to elevation 60 it holds about 1 ac-ft of water. The pond discharges through an 18" RCP to a point at the head of a former natural swale. The peak discharge for this pipe (100 year full development) has been calculated at 20 cfs. While the discharge from this pipe under existing conditions is less than 20 cfs it has probably been 10-15 cfs in the past. Because of the steep slope of the swale this flow has caused considerable erosion of the native soils and created a deep gully. At the same time the adjacent banks have failed and large areas have slumped three to five feet. In order to more fully utilize the capacity of the existing detention basin it is proposed to install a town standard detention basin outlet control structure with a 10" orifice. The peak flow through the orifice for the 100 year storm will be 6.4 cfs (Detention Basin Analysis dated May 28, 1999) and the water elevation will be 58.41. If the grate to the orifice becomes clogged, or the storm exceeds the 100 year storm, water will enter the `C-L' top on the outlet structure and flow to the existing 18" RCP. It is estimated that the existing 18" RCP has a capacity of 20 cfs under those head conditions. EMERGENCY SPILLWAY The detention basin will be provided with a new emergency overflow spillway. This spillway will be set at an elevation of 59.50 and is designed for a flow of 19.5 cfs. The flat portion of the spillway will be 15' wide with sides at 4:1. It will narrow to 10' wide as it runs down a 25% slope to the new CB. Overflow water will enter a new 'C-L' top and new 18" CPE(S) located at the end of the existing 18" RCP. 18" CPE(S) Instead of water from the detention pond discharging to the head of the steep swale, 150' of 18" Corrugated Poly-Ethylene (Smooth wall) will be installed and the existing eroded swale filled. The pipe will be installed at a slope of 10% with a flow of about 20 cfs under minimal head conditions. RIPRAP BASIN A riprap basin will be installed at the outlet from the 18" CPE(S). The basin will be 10 feet long with an additional 5 foot apron. RIPRAP SWALE From the end of the basin the swale will be ripraped for a distance of 72 feet .
