DEP File No. 242-1045 Planning Board Notice of Decision dated 5/14/01 Schofield Brothers of New England, Inc, has been designated as the "Environmental / Erosion Control Monitor" for the North Andover High School Project. The purpose of the Environmental /Erosion Control Monitor is to perform weekly inspections of the project site to insure compliance with the Order of Conditions issued by the Conservation Commission and the Special Permit issued by the Planning Board with respect to sediment and erosion controls, limit of work compliance, wetland replication and stormwater management issues. This is the fourth monthly inspection report prepared and submitted in compliance with the above referenced permits. It covers the period for the month of December 2001 through January 11, 2002. Attached are copies of the Inspection Reports (#13 and#14) relative to the inspections performed on December 19, 2001 and January 9, 2002, plus information relative to the completion of some minor work by the site contractor to address some minor remaining site issues on January 11, 2002. The latest routine Environmental /Erosion Control Inspections and Reports were performed by Mr. Bert Corey, an Engineer for SBNE. During December through January 11, the site work under the site preparation contract was essentially complete. The Site Contractor was no longer on-site except for work to address minor finish up items and the site was in generally good condition. For that reason, there was no need to inspect the site on a weekly basis and the inspections were reduced to two week intervals or following significant rainfall or snow melt conditions, and as necessary to inspect new work by the contractor to address erosion control issues. The site should remain stable through the winter under frozen ground conditions and inspections should continue as described above for that period. We recommend that weekly inspections resume during the late winter/ °�=)SCHOFIELD 13ROTI-IERS ENGINEERING • SI RN F IX PLANNING 20217 North Andover High School—Monthly Inspection Report—December 2001 to January 11,2002 January 18, 2001 Page 2 spring thaw (Late February/Early March) when erosion controls are more likely to need routine attention. Just prior to the December 19°i inspection, several days of significant rain gave the on-site erosion controls the first good test and gave us the opportunity to witness the performance of the various erosion control installations. In general, the erosion controls held up well and erosion was contained on site, with no threat to wetland resource areas. Some minor issues were found and the Contractor made corrections as necessary to address those issues. Relative to the Wetland Replication Areas, the contractor applied straw mulch around the newly planted shrubs to protect the plants through the winter as recommended. The wetland replication areas will be periodically monitored beginning next spring to assure survival of the plant materials and success of the wetland replication in conformance with the Performance Standards under the Wetlands Protection Act Regulations. As of the completion of work on the remaining erosion control issues by the Site Contractor on January 11`1i, 2001, the erosion controls are complete, functioning properly and the site is essentially "buttoned up"for the winter. It is our understanding that the Contractor under the Site Preparation Contract is responsible for maintenance of the erosion controls for 90 days following "substantial completion of the site work" unless the subsequent contractor takes over the site work prior to that. Based on our inspections, we have found that the work on the project has been performed in compliance with the Special Permit and Order of Conditions. Please let us know if there are any issues that we are not aware of. The attached inspection reports provide detailed information as to our findings.

Prior to this site inspection, there were several heavy rainfalls over the previous few days. It was, therefore, a good opportunity to observe the performance of the erosion and sediment controls, as well as the general stability of the site. 1. Sediment control barriers around the perimeter of the current work area: • Sediment control barriers remain in place and in good condition. • In the southwest corner of the site,just south of the temporary retaining wall, staked haybales should be placed to backup sediment fence at the location where runoff concentrates near temporary DMH Tl. 2. Loam stockpile area in the northern portion of the site: • The stockpile has been hydroseeded and only minor erosion and slumping of the stockpile was observed. • Sediment fence has been installed. • Sediment fence, located in southwest corner needs minor repair. 3. Ordinary borrow stockpile area in the northern portion of the site: • Some erosion of the stockpile was observed. • The stockpile has been hydroseeded. • Sediment fence has been installed. • Erosion of the stockpile is generally being contained by the sediment fence except at one location on the easterly side where the fence has been breached. This location needs repair and added support from haybales is recommended, as there seems to be a possibility for a heavy amount of silt here. Note that there is substantial distance between the stockpiles and the perimeter erosion controls discussed in Item 1 above, so there is no threat to the wetland resource areas. 4. Main entrance gate near trailers: • New stone has been added to the construction entrance and this item now in new condition. 5. Southern emergency entrance: • A large puddle has formed in the existing paved parking area in front of the entrance gate. The Contractor did create a shallow swale to direct water from this area to the southeastern catch basin as recommended in Inspection Report #12, but some additional minor grading needs to be done to allow runoff to enter the swale from the haul road. 20217 DiNiseo Design Partnership Inspection Repor7 No. 13 page 2 December 19, 2001 °r-:SCH0F1ELD BROTHERS F.sGINEERIAG • Sl R\E IAG • PL ANN IN(; 6. Catch basins: • Silt boots and hay bales at the catch basins are in good condition except as noted below. • Temporary Catch Basin T1 and T2, located between the existing school and the retaining wall need debris cleaned from the inlet silt boots. 7. Sediment basins and outlet structures: • Sediment basins are completed and are functioning properly. • With the recent rains, it is now evident that the grading along the west side of the haul road, to the north of Sediment Basin#3, does not form a swale that directs runoff to that Basin. As a result, runoff from the haul road and the adjacent area is bypassing the basin and the trap rock chute. Sediment is being carried down to the area at the easterly end of the temporary retaining wall. This is a significant problem that needs to be corrected ASAP. • Hydroseeding and matting has been completed. • In the southwest corner of the site near Sediment Basin #2, the grading is now complete. As expected, only a small area does not drain to the basin. Additional erosion controls (silt fencing and hay bales) have been installed to control any erosion at that small area, and appears satisfactory except as noted below. • Just to the west of Sediment Basin#2, soil has washed away from area immediately around the new 21" drain pipe, exposing the top and side surfaces. The grade needs to be brought up in this area and the soil stabilized to prevent continued erosion around this pipe that could damage the installation. 8. Other erosion control items. • A gully has formed in the slope to the Stone Interceptor Sub-drain just to the south of the Ordinary Borrow Stockpile. Silt is beginning to wash onto the stone interceptor sub-drain and it appears that other gullies are beginning to form at other locations on this slope. This needs to be addressed ASAP to minimize damage to the Stone Interceptor Drain. • Sediment fence,just north of CB#1 needs minor repair. 9 Other drainage structures: • All major drainage structures have been installed and appear to be functioning. • The stone outfall at the sub-drain outlet has been properly repaired and the sub-drain appears to be functioning. 10. Wetland replication areas: • Both wetland replication areas have been augmented with organic-rich loam, appropriate plantings, peat moss, and seed. • Plants could be mulched with hay to protect against freezing temperatures. 20217 DiNisco Design Partnership Inspection Report No. 13 Page 3 December 19, 2001 °°SCIIOFIEI.D RRMIJITS Ell U,I\F.1.:11 1\f: tiI;K!-I(SI\G PL:!\SI\G MSEM 11. Impermeable barrier and easterly embankment: • The embankment has been graded and covered with loam. • The embankment slope has been hydroseeded and jute matting has been installed on the steepest portions of the slopes. The work seems to be functioning well at this time and no erosion of the embankment was observed. 12. General: ® The site is clean and orderly. As mentioned at the beginning of this report, considerable rainfall occurred in the days prior to the inspection and the site generally weathered the storm well. The rains did reveal a few problems that need to be addressed and are discussed above. These are general internal site erosion conditions and do not impact off-site areas or wetland resource areas. Timely correction of these items will assure that no sediment leaves the work site. ® The emergency access way between the existing school and the retaining wall is in a very muddy condition. The area is relatively flat and no erosion is occurring,but consideration should be given to applying crushed stone or other corrective method to allow easier access for emergency vehicles. 20 DiNisco Design Partnership Inspection Report No. 13 December 19 2001 — - Page E=)SCHOREID BROTHERS ENGINEERING • SURNFYING PLANNING Schofield Brothers of New England.

The site is essentially "buttoned up" for the winter months. The site is unchanged from the last inspection, except for the repairs completed by the site contractor in response to the Inspection No. 13 report. In addition, I met with Bob Johnson (R. Zoppo Corp.) to discuss and review three items from Inspection Report No. 13. The results of those discussions are listed below in the relevant sections. Overall, the site remains stable; there are no new issues that need to be addressed. 1. Sediment control barriers around the perimeter of the current work area: • Sediment control barriers remain in place and in good condition. 2. Loam stockpile area in the northern onion of the site: • The stockpile has been hydroseeded and only minor erosion and slumping of the stockpile was observed. • Sediment fence remains in place and in good condition. 3. Ordin ry borrow stockpile area in the northern portion of the site: • Some erosion of the stockpile was observed. • The stockpile has been hydroseeded. • Sediment fence remains in place and in good condition. • Sediment fence on the easterly side has been repaired including added support from haybales at the location recommended. Note that there is substantial distance between the stockpiles and the perimeter erosion controls discussed in Item 1 above, so there is no threat to the wetland resource areas. 4. Main entrance gate near trailers: • New stone had been added to the construction entrance and this item now in new condition. 5. Southern emergency entrance: • A large puddle has formed in the existing paved parking area in front of the entrance gate. The Contractor did create a shallow swale to direct water from this area to the southeastern catch basin as recommended in Lispection Report #12, but some additional minor grading needs to be done to allow runoff to enter the swale from the haul road. o Inspected with Bob Johnson; a portion along the side and at the base of the haul road needs to be cut away to give runoff and puddling a chance to run towards the swale. 1/11102 Postscript: A sliallow trench was cut and filled with 314" crushed stone along the base of the lhartl road. Along the east side of the lurid road, near-the swale, was i 20217 DiNisco Design Partnership Inspection.Report No. 14 Page 2 , l January 17, 2002 °` SC11()F1E1.D BROTHERS F;\( IVI?P:RI`G tiCH1-h:11�G _1'LA\\I\G slightly regraded. It was easy to see the large puddle at the entrance gate emptying into the swale and should reduce the paddle significantly. This issue has now been addressed to the extent feasible and is satisfactory. 6. Cate_ h basins: • Silt boots and hay bales at the catch basins are in good condition. 7. Sediment basins and outlet structures: • Sediment basins are completed and are functioning properly. • With the recent rains, it is now evident that the grading along the west side of the haul road, to the north of Sediment B #3, does not form a swale the haul road and the directs runoff to that Basin. As a result, no adjacent area is bypassing the basin and the trap rock chute. Sediment is being carried down to the area at the easterly end of the temporary retaining wall. This is a significant problem that needs to be corrected ASAP. o Inspected with Bob Johnson; the existing grading along the west side of the haul road will be a cut and regraded ttIn the area of the chute,the grading ad towards and into the trap rock will be such that the runoff has the ability to enter the chute. Trap rock and 3/q" crushed stone will be placed in this area. The cut will start approximately 50 feet north of the chute, at the edge of the haul road and will extend to the west as it approaches the chute. 1111102 Postscript: A shallow swale was cut alongside the haul road as discussed. Trap rock was placed in front of the existing trap rock chute and 3/a" crushed stone was placed along the entire length of th.e swale. A very shallow trench was cut across the haul road to direct additional runoff towards the trap rock chute. The remaining crushed stone was used to repair and repack the haul road in this area. It was rairriaug during this work so it was easy to see that the majority of runoff traveling down the haul road was directed into the sivale towards the trap rock chute, and ultimately into sediment basin#3. This issue has now been addressed satisfactorily. tiVe will need to keep an eye on this area to make sure it conntinues to drain properly. • Hydroseeding and matting has been completed. • In the southwest corner of the site near Sediment Basin #2, the grading is now complete. As expected, only a small area does not drain to the basin. Additional erosion controls, silt fencing and hay bales, has been installed to control any erosion at that small area, and appears satisfactory. ® Just to the west of Sediment Basin#2, soil has washed away from area immediately around the new 21" drain pipe, exposing the top and side surfaces. The grade needs to be brought up in this area and the soil stabilized to prevent continued erosion around this pipe that could damage the installation. o Inspected with Bob Johnson; grading at the exposed drain pipe will be such that runoff from the haul road will have a tendency to move towards the i 20217 DiNisco Design Partnership Inspection Report No. Id Page 3 January 17, 2002 _-- --- — °�SCIII)FULD BROTHERS ENGINEERING • St RN Eyl"G PLA\SI\G basin. Approximately 75 feet north of this area, there may be a tendency for water to run off the haul road, stream along its edge, and cross over the drain pipe as it heads toward Sediment Basin #2. New grading will slightly elevate the side of the haul road along this length. In addition, two rows of 2 or 3 haybales will be positioned along the path where runoff seems to be occurring, to slow down any runoff prior to crossing the drain pipe. 1/11102 Postscript: The soil excavated to construct the swale along the haul road was used to cover the exposed pipe and to create a berm along the 75' length of road. Because of the working conditions, I was told it would be difficult to smooth the berm. Ha>>bales were placed as discussed. As expected, noticeable runoff flow was following the berm towards sediment basin#2. This issn.te has noiv been addressed satisfactorily. We will need to keep an eye on this area to make sure it continues to drain.properly. 8. Other erosion control items. ® A few gullies had formed in the slope to the Stone Interceptor Sub-drain just to the south of the Ordinary Borrow Stockpile. In the area where the largest gully had formed, haybales have been placed to provide backup to the silt fence at the top of the slope and a 30-foot silt fence with haybales has been placed at the bottom of the slope, immediately north of the stone interceptor sub-drain. The area appears in satisfactory condition at this time. 9 Other drainage structures: • All major drainage structures have been installed and appear- to be functioning. • The stone outfall at the sub-drain outlet has been properly repaired and the sub-drain is functioning. 10. Wetland replication areas: ® Plants have been mulched with hay to protect against freezing temperatures. 11. Impermeable barrier and easterly embankment: • The embankment slope has been hydroseeded and jute matting has been installed on the steepest portions of the slopes. The work seems to be functioning well at this time and no erosion of the embankment was observed. 12. General: e The site is clean and orderly. 1111102 Postscript: With the repairs and adjustments made by the contractor on. January 11, 2002, all issues have been addressed and the site is i.n satisfactory condition at this time. 20217 DiNisco Design Partnership Inspection Report No. 14 January 17, 2002 Page 4 '==)=DSCH0F1E1D ENGINEERING • SURVEYING PLANNING Schofield Brothers of New England, Inc. 1071 Worcester Road Framingham,NIA 01701-5298 508-879-0030 February 19, 2002 1-800-696-2874 FAX 508-II79-1797 opt 20217 TO: North Andover Conservation Commission North Andover Planning Board D.

DEP File No. 242-1045 Planning Board Notice of Decision dated 5/14/01 Schofield Brothers of New England, Inc. has been designated as the"Environmental/ Erosion Control Monitor" for the North Andover High School Project. The purpose of the Environmental / Erosion Control Monitor is to perform periodic inspections of the project site to insure compliance with the Order of Conditions issued by the Conservation Commission and the Special Permit issued by the Planning Board with respect to sediment and erosion controls, limit of work compliance, wetland replication and storrnwater management issues. This is the fifth monthly inspection report prepared and submitted in compliance with the above referenced permits. It covers the period January 12, 2002 through February 8, 2002. Attached are copies of the Inspection Reports (#15 and #16) relative to the inspections performed on January 25, 2002 and February 8, 2002. During this time frame, the site has remained stable and in good condition. The combination of winter- conditions and absence of any site work has lead to an uneventful period. At both inspections, there was observable runoff. The January 25 inspection followed a day of rain and the February 8 inspection occurred during warmer weather when snowmelt was occurring. During both inspections, erosion controls were in good condition and were functioning properly, including the repairs made by the site contractor on January 11. Observations made during the two (2) visits were as follows: ® Runoff from the haul road at the emergency entrance that usually formed a large and deep puddle at the gate as it accurnulated at the base of the slope was visibly flowing into the Swale and catch basin, considerably reducing its contribution to that area. o=)SC110FIELD BROTHERS ENGINEERING • SCR\FNIM; • PLANNING 20217 North Andover High School— Monthly Inspection Report—January 12, 2002 to February 8, 2002 Page 2 • Runoff that typically followed the haul road and bypassed sedimentation basin#3 was flowing into the trap rock chute leading to sediment basin #3. Repairs made to this area are working properly to direct the majority of runoff, especially the flow occurring on the west side of the haul road, towards the trap rock chute. • On the west side of the site, runoff along the haul road has been following the berm and into sediment basin#2. No erosion around the drain pipe has occurred. • At the southern end of the borrow area, runoff continues to flow down the slope in gullies, the largest flow heading towards a silt fence installed to protect the stone interceptor drain. Some of the silt is beginning to wash around the sides and onto the stone, Although not a problem at this time, attention may be needed in the future to prevent large amounts of silt from washing onto the stone. • No breaches of the exterior sedimentation fence have occurred. • The only minor attention needed is to repair a torn silt fence at the north end of the borrow area. Overall, the site remains in a very good and stable condition. In addition to repairs previously made, the site seems to be benefiting from the relatively low amount of precipitation experienced to date. Based on our inspections, we have found that the work on the project has been performed in compliance with the Special Permit and Order of Conditions.

Similar to the last inspection, the majority of runoff was flowing towards the appropriate structures. Other than a minor repair that is needed to fix a torn silt fence (located at the loam stockpile), the site essentially remains unchanged and in stable condition. 1. Sediment control barriers around the perimeter of the current work area: • Sediment control barriers remain in place and in good condition. 2. Loam stockpile area in the northern portion of the site: • The stockpile has been hydroseeded and only minor erosion and slumping of the stockpile was observed. • Sediment fence remains in place and in good condition. • The silt fence, at the north side, has been torn from a stake. 3. Ordinary borrow stockpile area in the northern portion of the site: • Some erosion of the stockpile was observed. • The stockpile has been hydroseeded. • Sediment fence and additional haybale support mentioned in the previous report remains in place and in good condition. • The sediment fence is working well; there is a noticeable amount of silt being held back. 4. Main entrance gate near trailers: • The stone construction entrance is in very good condition. 5.

The adjacent drain pipe remains covered andtof tlbe gullies have the Howe the berm except an insignificant one at t he end enters Sediment Basin#2. S. Other erosion control items. • A few gullies had formed in the slope to the Stone Interceptor Sub-drain just to the south of the Ordinary Borrow Stockpile. In the area where the largest gully had formed, haybales have been placed to provide backup to the silt fence at the top of the slope and a 30-foot silt fence with haybales has been placed at the bottom of the slope, immediately north of the stone interceptor sub-drain. The area appears in satisfactory condition at this time. o Although the silt fence is stopping the silt from entering the stone interceptor sub- drain as the gully (now—1S" wide x 5"deep) approaches it, the silt is running towards the sides of the silt fence and is spilling onto the stone. On the east-end, a 3' delta has formed and has made it across the stone. This is not critical at this point, but will need to be addressed soon. 9 Other drainage structures: ® All major drainage structures have been installed and appear to be functioning. ® The stone outfall at the sub-drain outlet to the east of the haul road is flowing and appears to be functioning properly. 10. Wetland replication areas: • No change from previous report. 11. Impermeable barrier and easterly embankment: ® A small gully has formed alongside the northerly edge of the jute matting from the top of the slope to the bottom of the slope and a small silt delta (3'x4') has formed on the haul road.

Ordinary borrow stockpile area in the northern portion of the site: • Some erosion of the stockpile was observed. • The stockpile has been hydroseeded. • Sediment fence and additional haybale support mentioned in the previous report remains in place and in good condition. • The sediment fence is working well; there is a noticeable amount of silt being held back. 4. Main entrance gate near trailers: • The stone construction entrance is in very good condition. 5. Southern emergency entrance: • 1/11102 Postscri>,t.: A shallow trench was cut and filled with crushed stone along the base of the haul i-oacl. Along the east side of the haul road, neat. the siyale, was slightly reg7-adecl. It ryas easy to see the large puddle at the entrance gate emptying into the s►vale and should reduce the puddle significantly. This issue has notiv been addressed to the extent feasible and is satisfactory. • The repairs to this area seem to be working correctly. There was noticeable runoff flowing to the catch basin. The puddle that usually formed at the entrance gate was almost non-existent. 6. Catch basins: • Silt boots and hay bales at the catch basins are in good condition. 7. Sediment basins and outlet structures: • Sediment basins are completed and are functioning properly. 20217 DiNisco Design Partnership Inspection Report No. 15 January 31, 2002 Page 2 RSCHOHLLD BROTHERS ENGINEERING • sL.-R�EYING • PLANNING • With respect to Sediment Basin#3, the Swale constructed alongside the haul road and into the trap rock chute seems to be working properly. It was easy to see that almost all the runoff from this area was directed into the trap rock chute and into the basin. • With respect to Sediment Basin#2, repairs seem to be working properly. The adjacent drain pipe remains covered and no noticeable gullies have formed alongside the berm except an insignificant one at the end of the haul road/berm where the flow enters Sediment Basin#2. 8. Other erosion control items. • A few gullies had formed in the slope to the Stone Interceptor Sub-drain just to the south of the Ordinary Borrow Stockpile. In the area where the largest gully had formed, haybales have been placed to provide backup to the silt fence at the top of the slope and a 30-foot silt fence with haybales has been placed at the bottom of the slope, immediately north of the stone interceptor sub-drain. The area appears in satisfactory condition at this time. o Although the silt fence is stopping the silt from entering the stone interceptor sub- drain as the gully (now —18" wide x 5"deep) approaches it, the silt is running towards the sides of the silt fence and is spilling onto the stone. On the east-end, a 3' delta has formed and has made it across the stone. This is not critical at this point, but will need to be addressed soon. 9. Other drainage structures: • All major drainage structures have been installed and appear to be functioning. • The stone outfall at the sub-drain outlet to the east of the haul road is flowing and appears to be functioning properly. 10. Wetland replication areas: • No change from previous report. 11. Impermeable barrier and easterly embankment: • A small gully has formed alongside the northerly edge of the jute matting from the '.... top of the slope to the bottom of the slope and a small silt delta (3'x4') has formed on the haul road. Not a problem at this time, but this may need some attention in the future. We will need to keep an eye on this area. 12. General: • The site is clean and orderly. 20217 DiNisco Design Partnership Inspection Report No. 15 Januaty 31, 2002 page 3 Pa r c h i t e c t s a n d p l a n n e r s Limited 17 ,-bb E OBSERVATION REPORT NO. 1 APP 0 m ` %` Project: North Andover High School 1kT11TrH AhIpC3W Date: 26 March 2002 FL`\ivivciv 'Psl T`¢``"' Location: North Andover High School Cafeteria Present: North Andover School Building Committee Steve Bullis Harold Duchame Superintendent of Schools Bill Allen North Andover School Department Paul Szymanski Vinnie Valentino North Andover High School Susan Nicholson North Andover Building Commissioner Bob Nicetta North Andover Dept. of Public Works(DPW) Bob Beshara North Andover Fire Department Lt.

DEP File No. 242-1045 Planning Board Notice of Decision dated 5/14/01 Schofield Brothers of New England, Inc. has been designated as the"Environmental/ Erosion Control Monitor" for the North Andover High School Project. The purpose of the Environmental /Erosion Control Monitor is to perform periodic inspections of the project site to insure compliance with the Order of Conditions issued by the Conservation Commission and the Special Permit issued by the Planning Board with respect to sediment and erosion controls, limit of work compliance, wetland replication and stormwater management issues. This is the sixth monthly inspection report prepared and submitted in compliance with the above referenced permits. It covers the period February 9, 2002 through March 15, 2002. Attached are copies of the Inspection Reports (#17, 4118, and #19) relative to the inspections performed on February 22, 2002, March 4, 2002, and March 15, 2002. During this time frame, the site experienced the largest amount of runoff during the winter season. Snowmelt and "frost-out" conditions contributed to the formation of larger gullies and erosion. The site contractor was back on site, March 7, to make the necessary repairs outlined in the inspection reports. It should be noted that all erosion issues were contained within the site and there were no impacts to any of the resource areas. Overall, the site remains in very good condition. A meeting with the General Contractor, JT Callahan, and Architect, DiNisco Design Partnership took place on March 15, 2002 at the site to review the condition of the site and the expectations going forward. Observations made during the three (3) visits were as follows: The haul road at the southern emergency entrance experienced a large amount of erosion. Several large gullies were formed and deposits accumulated at the entrance gate upsetting the tendency for runoff to flow towards the southeast catch basin. Silt was '==SCHOFIELD BROTHERS ENGINEERING SI:R�"F.l'ING PLANNIN<: ;,, 20217 North Andover High School—Monthly Inspection Report—February 9, 2002 through March 15, 2002 Page 2 deposited on the pavement immediately outside the gate. This area was fully restored by the site contractor and remains in good condition. • Sedimentation Basins 41, 92, and #3 continued to function properly, collecting the majority of runoff from their respective areas. • A gully that began to get too large,just south of Sediment Basin 43 and along the haul road, was repacked with medium dense crushed stone. The gully has begun to reform but the patch along the haul road remains in very good condition. The area that this gully feeds has been acting as another sedimentation basin and the sedimentation fence/ hay bales are collecting silt that would flow towards the southern entrance and school parking area. Erosion continued to occur down the slope above the stone interceptor drain. Silt deposits the stone interceptor drain were removed, the silt fence was extended, and no new deposits have occurred. ® A large gully has formed at the top of the slope above catch basin#3. The General Contractor plans to fill it with riprap stone. Silt/fines that deposited on the on the crushed stone covering the stone interceptor drain and around the catch basin have been removed and the catch basin has been protected with filter fabric. No new deposits have occurred. • No breaches of the exterior sedimentation fence have occurred. • Several repairs have been made to the silt fence surrounding the stockpile. One section of fence, along the east side where the heaviest amount of silt had been depositing, was pushed down and covered. This area was repaired and heavy silt deposits held back by the fence were removed. ® A"blowout" along the east bank occurred and has been filled with riprap. The source of seepage that created this area where the soil has slumped away from the bank is unknown at this time and further exploration is ongoing. The response from the site contractor to make repairs in a timely fashion, and as stated in previous reports, the relatively low amount of precipitation experienced during the winter season has helped to keep the site in very good and stable condition. JT Callahan is taking over the site as the General Contractor and is about to begin the next phase of construction. Weekly site inspections by SBNE will begin as soon as construction resumes. ==SCHOFIELD BROTHERS ENGINEERING • SURVEYING • 1-11NING OEM20217 N orth Andover High School—Monthly Inspection Report—February 9, 2002 through March 15, 2002 Page 3 Based on our inspections, we have found that the work on the project has been performed in compliance with the Special Permit and Order of Conditions.

INSPECTION SUMMARY The site inspection was performed because it coincided with the meeting mentioned above. The site was relatively dry and no runoff was observed except for a small amount of seepage occurring along a short section at the northern portion of the east bank. This small amount of seepage may be occurring from the wetland in the immediate area. The site remains in stable condition. Previous reports have been pared down and new comments have been placed in italics. 1. Sediment control barriers around the perimeter of the current work area: ® Sediment control barriers remain in place and in good condition. 2. Loam stockpile area in the northern portion of the site: • The hydroseed application may have been washed down the side of the pile. More erosion of the stockpile has occurred and observable deposits of silt are being held back by the sedimentation fence. • At the meeting, it was concluded that there is a high likelihood grass will grow on the loam pile to stabilize it even though a major portion of the hydroseed application had been washed down the sides. 3. Ordinary borrow stockpile area in the northern portion of the site: • Erosion continues to occur, striations can be seen on the slopes of the pile. A significant amount of the hydroseed application appears to have been washed down the side of the pile. • Sediment fence and additional haybale support on the easterly side, mentioned in the previous report, remains in place and in good condition; it is working well; there is a noticeable amount of silt being held back. • The sediment fence remains in good condition around the perimeter of both stockpiles. • At the meeting, it could not be determined whether grass will not become established on the ordinary borrow stockpile. Further monitoring will be necessary. 4. Main entrance Rate near trailers: ® The stone construction entrance is in very good condition. 5. Southern emergency entrance: • No Fuddles existed at the entrance gate. • The hazel road remains in stable condition; a small amount of erosion was visible along the east side near the Swale, which is to be expected L20217 co Design Parbiership ction Report No. 19 Page 2 h 15, 2002 'C=D=)SCHOFIELD BROTHERS ENGINEERING • SURVEYING - PLANNING 6. Catch basins: • Silt boots and hay bales at the catch basins are in good condition 7. Sediment basins and outlet structures: • Sediment basins are functioning properly. • The area just south of Sediment Basin#3, an area designated to receive overflow from Sediment Basin#3, is presently functioning as a secondary sedimentation basin. 8. Other erosion control items. • A few gullies remain in the slope above the Stone Interceptor Sub-drain,just south of the Ordinary Borrow Stockpile. The largest gully has haybales placed at its beginning and a silt fence is installed at the toe of the slope to protect silt from washing onto the pea-stone covering the sub-drain. • A deep gully (2' wide x 28" deep)travels down the slope towards CB#3. Repairs previously noted were the removal of the silt covering the stone interceptor sub-drain, removal of the silt at the beehive grate, and covering the grate with filter fabric. o The general contractor will take control of this area and intends to fill the gully ivith riprap stone to stabilize that it. 9. Other drainage structures: • All major drainage structures appear to be functioning. • The stone outfall at the sub-drain outlet to the east of the haul road is flowing and appears to be functioning properly. 10. Wetland replication areas: • No change from previous report. 11. Impermeable barrier and easterly embankment: • 3/4/02: This (blowout) area is approximately 5' wide and 1-1/2' deep at its deepest point. A 7" diameter hole is located at the back wall, bottom center of the gully. At this point, I am wondering if subsurface flow is concentrating in this area and caused the blowout. Repaired — leftover riprap/soil has been used to fill this area • This blowout is a concern; although no observable runoff was occurring at the time of the inspection, small deltas of silt were extending onto the haul road from the repaired area. It is likely that this condition may continue long term and that the source of seepage creating the hole and blowwout should be found and corrected. In addition,just north of this area, a small amount of seepage is flowing through the bank and towards the haul road This may be coming from the wetland in the immediate area. The General Contractor, JT Callahan, will investigate these areas. 12. General: • The site is continues to be clean and orderly. 20217 DiNisco Design Partnership Lrspection Report No. 19 Allarch 15, 2002 Page_3 oo SCHOFIELD ENGINEERING • SURVEYING PLANNING Schofield Brothers of New England,Inc. 20217 1071 Worcester Road OEM Framingham,MA 01701-5298 508-879-0030 1-800-696-2874 To: Mr. Rick Rice FAX 508-879-1797 DiNisco Design Partnership 87 Summer Street Boston, MA 02110 Cc.: North Andover Conservation Commission North Andover Planning Board From: Bert Corey, Staff Engineer ' l-J- Date: March 8, 2002 Re: North Andover High School (20217) INSPECTION REPORT Inspection No.: 18 Date of Inspection: March 4, 2002 By: Bert Corey INTRODUCTION The purpose of these inspections is to observe and review the project work relative to compliance with the Orders of Conditions issued by the North Andover Conservation Commission and the Special Permit issued by the North Andover Planning Board with respect to sediment and erosion controls, limit of work compliance, and stormwater management issues.

EBSCIIOFIELD BROTHERS ENGINEERING • SUR�'Eti'ING PLANNI`G INSPECTION SUMMARY The site inspection followed a period of rain on Sunday, 3/3/02; no snow or ice was present, there were small ponds of water in the sediment basins, and no runoff was observed. No new issues have been found; the gullies and silt deposits mentioned in the previous inspection report continue to get wider and deeper. Following the repairs made on 3/7/02, the site is in stable condition. 1. Sediment control barriers around the perimeter of the current work are Sediment control barriers remain in place and in good condition. 2. Loam stockpile area in the northern portion of the site: ® The stockpile has been hydroseeded and only minor erosion and slumping of the stockpile was observed. The hydroseed application may have been washed down the side of the pile. More erosion of the stockpile has occurred and observable deposits of silt are being held back by the sedimentation fence. ® 317102 Repairs to items mentioned in previous reports include: o The sediment fence, at the north side, has been torn from a stake. Repaired o The sediment fence, at the southwest corner is sagging and needs maintenance. Repaired o A small amount of runoff is undermining the sediment fence at the northwest; this area can be found where a small amount of silt has run down the side of the haul road. Repaired o In addition, a broken fence stake ivas repaired and all locations along the silt fence, where ends overlap, were fia•ther secured and tightened, essentially closing any "V" openings at the stakes. 3. Ordinary borrow stockpile area in the northern portion of the site: ® Some erosion of the stockpile was observed. Erosion continues to occur, striations can be seen on the slopes of the pile. A significant amount of the hydroseed application appears have been washed down the side of the pile. ® Sediment fence and additional haybale support on the easterly side, mentioned in the previous report, remains in place and in good condition; it is working well; there is a noticeable amount of silt being held back. ® 3/71102 Repairs to itenis nlentioned in previous inchide: o Immediately north of the haybale reinforced area mentioned above, a portion of sediment fence not protected with haybales has been pushed over and buried by silt. Repaired ® In addition: silt being held back by the haybales was i•einoved to give additional capacity at this point and haybales were extended further north along the silt fence. i 20217 DiNisco Design Partnership Inspection Report No. 18 page 2 March 8, 2002 "EDSCH®FIELD BROTHERS GIN ENEERING SURVF.S'ING PLA\KING W o Approximately 25' north of this location, two ends of the sediment fence meet. A means to close the opening where the two ends meet may prevent runoff from finding its way through this location and causing a situation similar to the one noted below. Repaired o At the sediment fence at the southeast corner, runoff seems to be flowing through a location where two ends of the sedimentation fence meet. Repaired ® The runoff continues to an area near the top of the slope leading to the stone interceptor drain. It has created a deep gully (1-1/2' wide x 2' deep) traveling down the slope. Silt from this process has covered approximately 50' of the stone interceptor drain and covered approximately 3/a of the inlet grate. The opening where the two ends meet should be closed, reinforced, and a silt boot should be installed at the inlet grate. ® 314102: The gully is now 2'wide by 28" deep. ® Repairs include: ® fence repaired silt removed from around catch basin and top surface of stone interceptor drain silt boot installed and secured over beehive grate at catch basin 4. Main entrance Rate near trailers: • The stone construction entrance is in very good condition. 5. Southern emergency entrance: e During this inspection, there was a shallow puddle at the entrance gate. By observing the high water mark around the catch basin and the noticeable amount of silt covering the parking lot immediately outside the gate, a pond must have formed at the catch basin and extended beyond the gate area. This area is functioning as a sedimentation trap during periods of higher runoff. Maintenance required at this time should be to remove silt from the paved area and to install a new silt boot at the catch basin. Both items repaired ® A large, double gully (-1-1/2' deep by—40' long) has formed along the east side of the haul road and a smaller gully (-1' deep by —15' long) has formed along the west side of the haul road. Most likely, these were the largest contributors of the silt found on the pavement. We recommend repairs of this area be made including installation of haybale checkdams positioned in a way to slow runoff flow, but not to impede possible future construction traffic. Repaired, the gullies have been filled 1vith existing washed out material along with 3/t" medium dense crushed stone fill. There is a slight pitch in the haul road to direct runoff to the srvale. After repairs were made the area was in excellent condition. ® 3141102: The.stone, gravel, and soils (from the gullies) have deposited at the toe of the slope and have eliminated the pitch allowing runoff to flow towards the sivale. In addition, the runoff from the gully is noiw forming a channel within the deposits and 20217 DiNisco Design Partnership Inspection Report No. 18 Page 3 March 8, 2002 BBSCHORELD BROTHERS ENGINEERING • SC'RIEti'I IG • PLANNING MIMMrunoff is it•avelling towaz•d the gate rather than the swale. The double gully is now 5- 112'wide. Repaired, see above 6. Catch basins: • Silt boots and hay bales at the catch basins are in good condition, except foz the following recommendations: o The silt boot should be replaced at the catch basin at the southern emergency entrance. Repaired • Silt boots should be installed at the three (3) beehive grates along the stone interceptor drain. Repaired, Catch Basin #3 was covered with filter fabric. Minot• amounts of silt cleaned from around Catch Basins#1 and#2 because grates could not be removed 7. Sediment basins and outlet structures: • Sediment basins are completed and are functioning properly. This continues to be the case for Sediment Basins 1, 2 & 3. • With respect to Sediment Basin 42, repairs seem to be working properly. The adjacent drain pipe remains covered and no noticeable gullies have formed alongside the berm except an insignificant one at the end of the haul road/berm where the flow enters Sediment Basin 92. The only difference from the previous inspection is that the gullies entering the basin are getting larger. o 314102: The 3/d"stone surrounding the stz•uctum has settled at the west face of the concrete structure, exposing 2' of fabric. Repaired • The area just south of Sediment Basin#3, an area designated to receive overflow from Sediment Basin#3, is presently functioning as a secondary sedimentation basin working fairly effectively to trap sediment it receives in the runoff flowing through a gully just off the haul road. This gully is now approximately 1' deep by 2' to 3' wide by 30' long. Some of the silt is being carried beyond t ern emergency corner of this area and onto the haul road,just north of the sou entrance. o 314102: The gully is now 20"deep at its deepest section.

This is not critical at this point, but will need to be addressed soon. ■ The gully is now 2' wide and 1' deep as it passes under the slope stabilization fabric. Captured silt is beginning to pull the fence down. Silt has washed onto stone interceptor drain from each side of the silt fence, each washout covers an area— 12' long. Repaired- the silt fence has been re,paired and the silt has been removed from the top sinface of the stone interceptor drain. • Silt is starting to get by the sedimentation fence, installed just north of the stone interceptor drain where it begins on the west side of the site, and is beginning to cover the crushed stone as it travels towards the beehive inlet grates. Silt boots should be installed at these two (2) inlets. Repaired—minor amount of silt has been removed from around the beehive grates, which could not be removed to install a silt boot. 9. Other drainage structures: • All major drainage structures have been installed and appear to be functioning. • The stone outfall at the sub-drain outlet to the east of the haul road is flowing and appears to be functioning properly. 10.

For reference, the Orders of Conditions issued for the project include: • DEP File No. 242-1045: Issued 2/21/01 • Planning Board Notice of Decision: Issued 5/14/01 Please note that issues needing attention have been put in bold-faced type and nov contntents have been put in italics. Please let me or Fred King at Schofield Brothers of New England, Inc. know if you have any questions regarding the information contained in this report. (EDE')SCHOFIELD BROTHERS ENGINEERING • SURD EYING • PLANNING BEEMEEM INSPECTION SUMMARY During this site inspection, no snow or ice was present, and no runoff was observed. From the observable conditions, it seems that the site experienced a large amount of runoff due to snowmelt and "frost-out" conditions. New gullies have been formed, existing ones have been enlarged and silt deposits are increasing as expected. Erosion control features are certainly being put to the test. It should be noted that the erosion occurring is being held on site and has not breached any of the perimeter erosion control features. All erosion control issues at this time are internal to the site and are not an immediate threat to wetland resource areas. To make sure that erosion remains under control, we recommend that the items needing attention receive repairs or maintenance as soon as possible in anticipation of spring rainfall and other typical seasonal conditions. 1. Sediment control barriers around the perimeter of the current work area: • Sediment control barriers remain in place and in good condition. Continues to be the case. 2. Loam stockpile area in the northern portion of the site: • The stockpile has been hydroseeded and only minor erosion and slumping of the stockpile was observed. The hydroseed application may have been washed down the side of the pile. • More erosion of the stockpile has occurred and observable deposits of silt are being held back by the sedimentation fence. However, there are some areas that need attention: • The sediment fence, at the north side, has been torn from a stake. • The sediment fence, at the southwest corner is sagging and needs maintenance. • A small amount of runoff is undermining the sediment fence at the northwest; this area can be found where a small amount of silt has run down the side of the haul road. 3. Ordinary borrow stockpile area in the northern portion of the site: • Some erosion of the stockpile was observed. Erosion continues to occur, striations can be seen on the slopes of the pile. • A significant amount of the hydroseed application appears have been ivashed down the side of the pile. • Sediment fence and additional haybale support on the easterly side,mentioned in the previous report, remains in place and in good condition; it is working well; there is a noticeable amount of silt being held back. • Some maintenance/repair issues that need to be addressed at this location are as follows: 20217 DiNisco Design Partnership Inspection Report No. 17 February 22, 2002 Page 2 '1E=:=SCIJOFIELD BROTHERS ENGINEERING • SURVEYING • PLANNING o Immediately north of the haybale reinforced area mentioned above, a portion of sediment fence not protected with haybales has been pushed over and buried by silt. Maintenance and repair is needed. o Approximately 25' north of this location, two ends of the sediment fence meet. A means to close the opening where the two ends meet may prevent runoff from finding its way through this location and causing a situation similar to the one noted below. o At the sediment fence at the southeast corner, runoff seems to be flowing through a location where two ends of the sedimentation fence meet. The runoff continues to an area near the top of the slope leading to the stone interceptor drain. It has created a deep gully (1-1/2' wide x 2' deep) traveling down the slope. Silt from this process has covered approximately 50' of the stone interceptor drain and covered approximately 3/a of the inlet grate. The opening where the two ends meet should be closed, reinforced, and a silt boot should be installed at the inlet grate. 4. Main entrance gate near trailers: • The stone construction entrance is in very good condition. This continues to be the case. 5. Southern emergency entrance: • During this inspection, there was a shallow puddle at the entrance gate. By observing the high water mark around the catch basin and the noticeable amount of silt covering the parking lot immediately outside the gate, a pond must have formed at the catch basin and extended beyond the gate area. This area is functioning as a sedimentation trap during periods of higher runoff. Maintenance required at this time should be to remove silt from the paved area and to install a new silt boot at the catch basin. • A large, double gully (-1-1/2' deep by—40' long) has formed along the east side of the haul road and a smaller gully (---1' deep by—15' long) has formed along the west side of the haul road. Most likely, these were the largest contributors of the silt found on the pavement. We recommend repairs of this area be made including installation of haybale checkdams positioned in a way to slow runoff flow, but not to impede possible future construction traffic. E. Catch basins: • Silt boots and hay bales at the catch basins are in good condition, except for the follotiving recommendations: • The silt boot should be replaced at the catch basin at the southern emergency entrance • Silt boots should be installed at the three (3) beehive grates along the stone interceptor drain. 20217 DiNisco Design Partnership Inspection Report No. 17 February 22, 2002 Page 3 ==SCHOFIELD BROTHERS ENGINEERING • SURVEYING • PLANNING 10011M 7. Sediment basins and outlet strictures: • Sediment basins are completed and are functioning properly. This continues to be the case for Sediment Basins 1, 2 & 3. • With respect to Sediment Basin#3, the swale constructed alongside the haul road and into the trap rock chute seems to be working properly. It was easy to see that almost all the runoff from this area was directed into the trap rock chute and into the basin. Although the water held in the basin receded to a silt layer, the high water mark was approximately 2-% 'from the top of the concrete structure. • With respect to Sediment Basin#2, repairs seem to be working properly. The adjacent drain pipe remains covered and no noticeable gullies have formed alongside the berm except an insignificant one at the end of the haul road/berm where the flow enters Sediment Basin #2. The only difference from the previous inspection is that the gullies entering the basin are getting larger. • The southwest corner in this area is holding up well. It cart be observed that a small amount of runoff has gone beyond the haybale/sedimentation fence hart no deposits of silt can be seen. • The area just south of Sediment Basin#3, an area designated to receive overflow from Sediment Basin #3, is presently fitnctioning as a secondary sedimentation basin working fairly effectively to trap sediment it receives in the runoff flowing through a gully just off the haul road This gully is now approximately I'deep by 2' to 3'wide by 30'long. Some of the silt is being carried beyond the haybales at the southeast corner of this area and onto the haul road,just north of the southern emergency entrance. 8. Other erosion control items. • A few gullies had formed in the slope to the Stone Interceptor Sub-drain just to the south of the Ordinary Borrow Stockpile. In the area where the largest gully had formed, haybales have been placed to provide backup to the silt fence at the top of the slope and a 30-foot silt fence with haybales (correction-no haybales are present at the 30 foot silt fence) has been placed at the bottom of the slope, immediately north of the stone interceptor sub-drain. o Although the silt fence is stopping the silt from entering the stone interceptor sub- drain as the gully (now—18" wide x 5"deep) approaches it, the silt is running towards the sides of the silt fence and is spilling onto the stone. On the east-end, a 3' delta has formed and has made it across the stone. This is not critical at this point, but will need to be addressed soon. ® The gully is now 2' wide and 1' deep as it passes under the slope stabilization fabric. Captured silt is beginning to pull the fence down. Silt has washed onto stone interceptor drain from each side of the silt fence, each washout covers an area — 12' long. • Silt is starting to get by the sedimentation fence, installed just north of the stone interceptor- drain where it begins on the west side of the site, and is beginning to 20217 DiNisco Design Partnership Inspection Report No. 17 Februaty 22, 2002 Page 4 =)=)SCHOEIEI.D BROTHERS ENGINEERING • SL'RNEYING • PLANNING cover the crushed stone as it travels towards the beehive inlet grates. Silt boots. should be installed at these two (2) inlets. 9. Other drainage structures: • All major drainage structures have been installed and appear to be functioning. • The stone outfall at the sub-drain outlet to the east of the haul road is flowing and appears to be functioning properly. Continues to be the case. 10. Wetland replication areas: • No change from previous report. 11. Impermeable barrier and easterly embankment: • A small gully has formed alongside the northerly edge of the jute matting from the top of the slope to the bottom of the slope and a small silt delta (3'x4') has formed on the haul road. Not a problem at this time, but this may need some attention in the future. We will need to keep an eye on this area. • Although the small gully mentioned above remains the same, another area approximately 28' north of this spot has washed away from the east bank. The area is approximately 4' wide where the bank meets the haul road, travels 9' up the bank, and is 1' deep. The silt from this area has washed onto the haul road. Repair and maintenance of the slope is recommended as soon as field conditions permit. 12. General: • The site is clean and orderly. • The northern reach of the haul road along the east side, the portion running east to west, and the portion running along the west side are in vef y good shape. 20217 DiNisco Design Partnership Inspection Report No. 17 February 22, 2002 Page 5 }� l a n n e r s �'�• {� a r c h i t e c t s a n d p Limited OBSERVATION REPORT NO. 2 Project: North Andover High School APR 1 1 2002 Date: 02 April 2002 Location: Job Site ,NN NO Gucci Present: North Andover School Building Committee (NABC) North Andover School Department (NASD) Paul Szmanski North Andover Building Commissioner (NABC) Robert Nicetta John T.

DEP File No. 242-1045 Planning Board Notice of Decision dated 5/14/01 Schofield Brothers of New England, Inc. has been designated as the"Environmental / Erosion Control Monitor" for the North Andover High School Project. The purpose of the Environmental /Erosion Control Monitor is to perform periodic inspections of the project site to insure compliance with the Order of Conditions issued by the Conservation Commission and the Special Permit issued by the Planning Board with respect to sediment and erosion controls, limit of work compliance, wetland replication and stormwater management issues. This is the seventh monthly inspection report prepared and submitted in compliance with the above referenced permits. It covers the period March 16, 2002 through April 9, 2002. Attached are copies of the Inspection Reports (#20, #21, and 922) relative to the inspections performed on March 26, 2002, April 1, 2002, and April 9, 2002. During this time frame the site continued to remain in very good condition, the ongoing erosion and sedimentation issues were contained within the site and there were no impacts to any of the resource areas. Gullies that were previously packed and regraded continued to form along the haul road at the southern emergency entrance and just south of Sedimentation Basin #3. A berm was installed across the haul road to prevent runoff from bypassing Sedimentation Basin#3 and contributing to the gully formations and flow to the southern gate area. Two areas along the east bank required further investigation, the "blowout" area and a small area just north of it, where seepage was seen to be flowing from the bank. The"blowout" seems to have been caused by flow following a seam of sandy soil in the compact glacial till. Solutions to resolve this issue are being developed. The seepage flowing through the bank was found to be coming from the sub-drain system indicating a probable blockage or break in the pipe, which needs to be investigated and corrected. Weekly inspections have been reinstated. o°SCHOFIELD BROTHERS ENGINE.EItING • SCR "EYING • PLANNING 20217 North Andover High School— Monthly Inspection Report— March 16, 2002 through April 9, 2002 Page 2 Observations made during the three (3) visits were as follows: • The exterior sedimentation fence, haybales and fence, remain in good condition and no breaches occurred. • Sedimentation Basins #1, #2, and #3 continued to function properly, collecting the majority of runoff from their respective areas. The stone filters surrounding the inlet structures are in very good condition. • Although the previous gullies were repaired, new gullies continue to form and enlarge along the sides of the haul road at the southern emergency entrance and along the haul road just below Sediment Basin#3. A berm, similar to a speed bump, has been installed to reduce the amount of surface runoff from reaching these areas and it has been suggested that haybales be placed at the southern entrance fence and gate to prevent silt from washing onto the pavement just outside the gate. The large gully that formed in the slope above catch basin #3 remains but erosion seems to be occurring at a slower rate. The Contractor plans to fill this gully with riprap stone. There has been some deposit of silt/fines onto the stone interceptor drain but no deposits have occurred around the catch basin inlet and it remains in very good condition, protected by filter fabric. • With the exception of one area at the ordinary borrow stockpile, where a slide occurred and covered four sections of silt fence, the silt fence surrounding the stockpile remains in good condition. The resulting deposit from the slide will have to be removed and the silt fence repaired. • An investigation of the "blowout" area took place with a geotechnical engineer and others. It has been surmised that the flow causing this blowout is from seepage traveling through a seam of sandy soil in the compact glacial till. The flow seems to only occur in response to precipitation. SBNE is working on a resolution to correct this localized flow. • A small area of seepage at the east bank that has been observed during dry periods has been found to be coming from the sub-drain system indicating a possible blockage or breakage. A method to assess the condition of the sub-drain pipe has been recommended. • Dewatering operations have begun, coinciding with the building footing installation. It has been noted that effluent should be directed overland towards the sedimentation �SCHOFIELD BROTHERS ENGINEERING • SCR�'F.ti-I\G 20217 North Andover High School—Monthly Inspection Report—March 16, 2002 through April 9, 2002 Page 3 basins without creating an erosion problem or passed thought a straw bale and filter fabric bin. Effluent should not be directed towards the haul road. ® An area for truck washing was established and washings were contained. - Dust control procedures are noted in the Erosion & Sediment Control Narrative - Attachment 3, dated October 4, 2000. Since a water ban is in place for the Town of North Andover, calcium chloride may be used as a dust control method. Granules or flakes may be applied at a rate that will keep the surface moist but not cause pollution.

It was raining for most of the day and ritnoff was observable. The site continues to remain in stable condition and there are no new issues. The General Contractor trailers have been placed on site and construction activities are anticipated to begin the first week in April. 1. Sediment control barriers around the perimeter of the current work area: Sediment control barriers remain in place and in good condition. 2. Loam stockpile area in the northern portion of the site: • The hydroseed application may have been washed down the side of the pile. More erosion of the stockpile has occurred and observable deposits of silt are being held back by the sedimentation fence. 3. Ordinary borrow stockpile area in the northern portion of the site: • Erosion continues to occur, striations can be seen on the slopes of the pile. A significant amount of the hydroseed application appears to have been washed down the side of the pile. • The sediment fence remains in good condition around the perimeter of the stockpile area. 4. Main entrance Rate near trailers: • The stone construction entrance is in very good condition. 5. Southern emergency entrance: • Puddling was occuring at the gate but was draining into the Swale and catch basin. • The haul road remains in stable condition; erosion continues along the east side of the road near the Swale, not significant at this time. 6. Catch basins: • Silt boots and hay bales at the catch basins are in good condition 7. Sediment basins and outlet structures: • Sediment basins are functioning properly. • The area just south of Sediment Basin#3, an area designated to receive overflow from Sediment Basin#3, is presently functioning as a secondary sedimentation basin. The previously repaired gully feeding this area is beginning to form again but is insignificant at this time. 8. Other erosion control items. • A few gullies remain in the slope above the Stone Interceptor Sub-drain,just south of the Ordinary Borrow Stockpile. The largest gully has haybales placed at its beginning and a silt fence has been exended at the toe of the slope to protect silt from washing onto the pea-stone covering the sub-drain. 20217 DiNisco Design Partnership Inspection Report No. 20 March 28, 2002 Page 2 c1==)CE)'SCHOFIELD BROTHERS ENGINEERING SCR�El'ING Fl-A\NfNG MEN= • A deep gully (2' wide x 28" deep) travels down the slope towards CB#3.

The site inspection followed a meeting with Bob (1==>E=)SCH0FIELD BROTHERS ENGINEERING - SCR%EYING • PLANNING Nicetta, Phil Briselli (JT Callahan Project Manager), and Richard Warner (Clerk of the Works) to review the "blowout"area. The southern entrance gate area was also reviewed with Bob and Richard. Gullies continue to form and enlarge along the haul road at the southern entrance gate and just south of sediment basin#3. Silt continues to deposit on the stone interceptor drain. It should be noted that although erosion and sedimentation continues to take place, it remains internal to the site with no impacts to resource areas. 1. Sediment control barriers around the perimeter of the current work area: • Sediment control barriers remain in place and in good condition. 2. Loam stockpile area in the northern portion of the site: • The hydroseed application may have been washed down the side of the pile.

Ordinary borrow stockpile area in the northern portion of the site: • Erosion continues to occur, striations can be seen on the slopes of the pile. A significant amount of the hydroseed application appears to have been washed down the side of the pile. • April 2: A section along the east side of the stockpile has slid down and covered four sections of the silt fence. Sediment removal and silt fence repair is needed. 4. Main entrance gate near trailers: • The stone construction entrance is in very good condition. • April 1:A stone parking area has been installed in front of the trailers. 5. Southern emergency entrance: • April 1:A small puddle formed at the gate and only a small amount was flowing towards the catch basin. • April 1: Gullies have formed along the sides of the haatl road and the wash out material is depositing at the bottom of the slope, which ultimately interferes with the tendency of the puddle to drain towards the southeast catch basin. If erosion continues to enlarge the gullies, regrading will be necessary. 6. Catch basins: • April 1: The silt boot at the catch basin in the emergency egress road that runs between the school and retaining wall should be replaced. Silt boots at other catch basins are in good condition. 7. Sediment basins and outlet structures: • Sediment basins are functioning properly. 20217 DiNisco Design Partnership Inspection Report No. 21 April S, 2002 Page 2 '1==)=SCH0FIELD BROTHERS ` FNGINEERING • SCRN EYING • PLANNING • The area just south of Sediment Basin #3, an area designated to receive overflow from Sediment Basin #3, is presently functioning as a secondary sedimentation basin.

At 10:35am the flow was approximately 113 of what was flowing a few hours earlier. • April 2:No flow coming from the blowout area. Fred King and geotechnical engineer will investigate this area Friday (4105102) to try to determine source and methods) to repair it. They will also investigate the seepage flowing through the bank just north of this area. 12. Dewatering: • April 1: Effluent from dewatering operations should be directed overland towards the sedimentation basins without creating an erosion problem or directed into a straw bale and fabric bin. The effluent should not be directed towards the haul road. 13. Truck Washing Area: • April 1:An area, approximately 20'x20'has been established for truck washing operations on the northern portion of the site, west of the ordinary stockpile. Haybales have been placed on the west and south sides and stone has been placed for driving. It will be important that the washings do not flow towards the stone interceptor drain. 14. General: • April 1: Construction is underway. 20217 DiNisco Design Partnership Inspection Report No. 21 April S, 2002 Page 4 'EE�:='--'SCH0F1E1D BROTHERS ENGINEERING • SURVEYING PLANNING Schofield Brothers of New England, Inc. 20217 1071 Worcester Road Framingham,MA 01701-5298 508-879-0030 1-800-696-2874 To: Mr. Rick Rice FAX 508-879-1797 DiNisco Design Partnership 87 Summer Street Boston, MA 02110 Cc.: North Andover Conservation Commission North Andover Planning Board From: Bert Corey, Staff Engineer Date: April 12, 2002 Re: North Andover High School (20217) INSPECTION REPORT Inspection No.: 22 Date of Inspection: April 9, 2002 By: Fred King INTRODUCTION The purpose of these inspections is to observe and review the project work relative to compliance with the Orders of Conditions issued by the North Andover Conservation Commission and the Special Permit issued by the North Andover Planning Board with respect to sediment and erosion controls, limit of work compliance, and stormwater management issues. For reference, the Orders of Conditions issued for the project include: • DEP File No. 242-1045: Issued 2/21/01 • Planning Board Notice of Decision: Issued 5/14/01 Please contact Bert Corey or Fred King at Schofield Brothers of New England, Inc. know if you have any questions regarding the information contained in this report. Items needing immediate attention are in bold. INSPECTION SUMMARY 1. Sediment control barriers around the perimeter of the current work area: 4/9/02 - Sediment control barriers remain in place and in good condition. =>=SCHOFIELD BROTHERS ENGINEERING • SURVEYING • PLANNING 2. Loam stockpile area in the northern portion of the site: • The hydroseed application may have been washed down the side of the pile. More erosion of the stockpile has occurred and observable deposits of silt are being held back by the sedimentation fence. • 4/9/02—No change from previous report noted above. 3. Ordinary borrow stockpile area in the northern portion of the site: • Erosion continues to occur, striations can be seen on the slopes of the pile. A significant amount of the hydroseed application appears to have been washed down the side of the pile. • 4/1/02: A section along the east side of the stockpile has slid down and covered four sections of the silt fence. Sediment removal and silt fence repair is needed. • 4/9/02—No change since previous report. '... 4. Main entrance gate near trailers: • 4/9/02: Area in very good condition. '.. 5. Southern emergency entrance: • April 1: A small puddle formed at the gate and only a small amount was flowing towards the catch basin. • 4/9/02: The gate area has been cleaned up and is in good condition. • April 1: Gullies have formed along the sides of the haul road just north of the gate and the wash out material is depositing at the bottom of the slope, which ultimately interferes with the tendency of the puddle to drain towards the southeast catch basin. If erosion continues to enlarge the gullies, regrading will be necessary. • 4/5/02: This specific item was discussed on site with representatives of DiNisco Design Partnership, the Contractor and others (see Items 2 and 3 of the attached memo of April 9, 2002). The problem appears to be partly a result of some runoff by- passing Sediment Basin#3. A berm (similar to a speed bump) will be installed in the access road to direct the flow to Sediment Basin#3. This will reduce the flow to the area at the Southern Access Gate and thereby minimize the problem. The contractor will also install a row of haybales along the gate and fence to control any remaining sediment. • 4/9/02: The berm has been installed. Haybales to be installed as discussed at the 4/5/02 site walk. 6. Catch basins: • 4/9/02: Silt boots at catch basins appear to be functioning properly. 7. Sediment basins and outlet structures: • Sediment basins are functioning properly. '.. 20217 DiNisco Design Partnership Inspection Report No. 22 April 9, 2002 Page 2 '1=D=SCH0FIELD BROTHERS ENGINEERING • SURVEYING • PLANNING • The area just south of Sediment Basin#3, an area designated to receive overflow from Sediment Basin #3, is presently functioning as a secondary sedimentation basin. The previously repaired gully feeding this area is beginning to form again but is insignificant at this time. • 4/1/02: The gully is getting larger and deeper and continues to make its way up the haul road. If the gully begins to cut its way into the haul road, interfering with travel, it will require repacking. • 4/9/02: This specific item was discussed on site with representatives of DiNisco Design Partnership, the Contractor and others during the site walk on 4/5/02 (see Items 2 and 3 of the attached memo of April 9, 2002). The problem appears to be partly a result of some runoff by-passing Sediment Basin#3. A berm (similar to a speed bump) has been installed in the access road to direct the flow to Sediment Basin#3 as discussed. This will reduce the flow to this area. 8. Other erosion control items. • A deep gully (2' wide x 28" deep) travels down the slope towards CB#3. The gully continues to get wider and deeper, the widest section occurring under the slope stabilization fabric. There were no silt deposits on or around the stone interceptor drain or catch basin#3 in the area below the gully. The General Contractor plans to fill this gully with riprap stone. • April 1: The gully continues to get larger and silt/fines have been washing out onto the crushed stone covering the stone interceptor sub drain. The filter fabric at the catch basin inlet is functioning properly. • April 1: At the southwest corner, some loose hay should be placed between the sedimentation fence and the perimeter chainlink fence. • 4/9/02: No change from previous report. 9. Other drainage structures: • 4/9/02: During the site walk on 4/5/02, it was determined that there was a problem with the access road sub-drain (see attached memo of 4/9/02, referred to as "Site 2"). Water is seeping onto the access road from the drain indicating a blockage or some other problem. This needs to be investigated. 10. Wetland replication areas: • No change from previous report. 11. Impermeable barrier and easterly embankment: • April 1: Building Commissioner noticed a considerable amount of flow emanating from the riprap covering the "blowout" area. At 10:35am the flow was approximately 1/3 of what was flowing a few hours earlier. • April 2: No flow coming from the blowout area. Fred King and geotechnical engineer will investigate this area Friday (4/05/02) to try to determine source and method(s) to 20217 DiNisco Design Partnership Inspection Report No.22 April 9, 2002 Page 3 =:�DSCHOFIELD BROTHERS FNGINFIRING SGRV"F,V'[NG PLA\\ING MEN= 0 repair it. They will also investigate the seepage flowing through the bank just north of this area. • 4/9/02: Blowout Area—This area was inspected on 4/5/02 by Richard Weber, geotechnical consultant, SBNE, representatives of DiNisco Design Partnership and the Contractor. See the attached memo dated 4/9/02 for additional information on this area. No seepage was occuring during this 4/9/02 inspection. SBNE to prepare a sketch plan for addressing this item. 12. Dewatering: • April 1: Effluent from dewatering operations should be directed overland towards the sedimentation basins without creating an erosion problem or directed into a straw bale and fabric bin. The effluent should not be directed towards the haul road. • 4/9/02: No change from previous report. 13. Truck washing Area: • April 1: An area, approximately 20'x20' has been established for truck washing operations on the northern portion of the site, west of the ordinary stockpile.
