OF PLANNING& Mr. Frank Taormina COMMUNITY DEVELOPMENT Staff Planner/Conservation Agent City of Salem Planning Department 120 Washington Street, 3rd Floor Salem, Massachusetts 01970 Subject: Salem, Massachusetts Task Order No. 18 Salem State College Alumni Field Peer Review of Drainage Facilities Final Letter Report Dear Mr. Taormina: In accordance with the terms of our agreement for Task Order No. 18, including Amendment No. 1, we have completed the Peer Review of the various documents associated with the design of the drainage facilities for the Salem State College Alumni Field. Presented in this Final Letter Report is a summary of our findings. Goal of Peer Review Salem State College proposes to upgrade the Alumni Field by replacing the natural grass surface with a synthetic turf field and a softball field, including a subsurface drainage system (the Project). Salem State College hired various consultants to design the field upgrades and prepare all required regulatory permit application documents, including a Notice of Intent. The Notice of Intent was reviewed by the Salem Conservation Commission, and the resulting Order of Conditions includes a Special Condition requiring a Peer Review prior to the commencement of construction activities. The Peer Review shall include, but not be limited to, a review of the Notice of Intent Application, verify compliance with the Massachusetts DEP's Stormwater Management Policy and the Massachusetts Wetlands Protection Act, and render an opinion as to whether the existing off-site drainage system will be negatively impacted as a result of the Project. Summary of Documents Reviewed The following documents were reviewed: • Notice of Intent Application dated February 10, 2005 prepared by Epsilon Associates, Inc. • Drainage Report dated February 2005 prepared by Geller DeVellis, Inc. 1 of 3 • Drainage Report dated February 2005, revised May 2005 prepared by Geller DeVellis, Inc. • Design plans prepared by various consultants entitled "Notice of Intent, Salem State College Alumni Field Renovation" (7 plans including cover sheet with varied dates extending from April 15, 2004 to February 10, 2005) • Revised design plans dated May 9, 2005, and accompanying letter dated May 11, 2005 from Geller DeVellis, Inc. to the Salem Conservation Commission • Bid specification section Nos. 02200 (Earthwork), 02722 (Storm Drainage System) and 02792 (Infilled Synthetic Turf System) dated March 18, 2005 and April 4, 2005, prepared by Geller DeVellis Inc. • Revised bid specification section No. 02722 (Storm Drainage System) • Geotechnical Investigation Report dated March 4, 2004 prepared by Geotechnical Services Inc. • Order of Conditions #64-387 issued by the City of Salem Conservation Commission, dated March 24, 2005 • WPA Appendix B-Stormwater Management Form dated February 8, 2005 prepared by Geller DeVellis, Inc. • Various letters and memorandums provided by the City of Salem. Summary of Recent Submittals Metcalf& Eddy submitted a Draft Letter Report to the Planning Department on May 3, 2005. The Draft Letter Report contained a number of review comments for consideration. Many of the review comments, if implemented, required changes to the Drainage Report, design plans and specifications. Subsequently, Metcalf& Eddy received from Geller DeVellis a copy of a revised Drainage Report (dated May 2005), a set of revised design drawings (dated May 9, 2005), a revised specification section 02722 (Storm Drainage System) and a transmittal letter addressed to the Conservation Commission dated May 11, 2005. Compliance with Stormwater Management Policy and Wetlands Protection Act We have reviewed all of the revised documents and find that all comments related to the Stormwater Management Policy and Wetlands Protection Act have been addressed. Therefore, it is our opinion that the overall project design and related documents are in compliance with the Stormwater Management Policy and Wetlands Protection Act. Impacts to Existing Drainage System The results of the revised modeling show that the estimated future (post-construction) peak flows for the 2, 10 and 100-year storms and the total volume for the 100-year storm will not 2 of 3 increase as a result of Project implementation. Therefore, it is our opinion that the existing off- site drainage system will not be adversely impacted after construction of the proposed Alumni Field renovations. Additional Review Comments The Draft Letter Report contained a document entitled "Attachment B"which identified additional miscellaneous review comments that, although not specifically related to the Stormwater Management Policy or the Wetlands Protection Act, never-the-less may affect the overall design intent. We have found that most of the review comments contained in Attachment B of the Draft Letter Report have been addressed, either in the revised design drawings or specification section 02722. However, presented in Attachment A are additional miscellaneous review comments related to the revised design drawings. We suggest that these comments be addressed during the early stages of construction. Revised documents addressing these comments do not need to be submitted to Metcalf& Eddy. Should you have any questions or if you would like to schedule a meeting to review the comments included herein, please do not hesitate to contact the writer at (781) 224-6094.

Meserve Project Manager Massachusetts Registered PE # 37249 MRM/mrm Enc.: 10 copies of Final Letter Report CC: Bruce Thibodeau Joseph Nerden 3of3 Attachment A Salem State College Alumni Field Peer Review of Drainage Facilities Miscellaneous Review Comments May 16, 2005 1. Notes requiring verification of the elevations of the existing pipe at proposed pipe crossings were added at two locations, but not in the location suggested in the Draft Report, Attachment B, item 5. Prior to construction, please also confirm the elevation of the existing 30-inch sewer where it crosses the proposed 12-inch diameter perforated drain on the west side of the site. 2. The designer has confirmed that a butterfly valve will be installed at each of the two discharge locations. Although the Draft Letter Report suggests a butterfly valve, other valve types, such as a ball valve, are acceptable at these locations, as determined by the designer. During the shop drawing review process, the Contractor should submit information related to operation and maintenance for the valves, and this material shall become the property of the City upon the completion of the work. 3. Sheet SP1.1 (revision date 5/9/05) requires protection of an existing drain manhole in the northwest corner of the site. However, sheet L2.1 (revision date 5/9/05) requires the same drain manhole to be removed. This apparent discrepancy should be resolved. 4. Sheet L2.1 (revision date 5/9/05) shows a proposed additional new sewer pipe that is not shown on the Sheet L2.1 initially reviewed as part of the Draft Letter Report. For the proposed new sewer identified as "Part of Alternate #2" in the southeast corner of the site, identify the sewer size and pipe type. If the existing sewer between each end of the proposed sewer is to be abandoned, ensure that the Contractor performs pipe abandonment work in accordance with City requirements. 5. Sheet L2.1 (revision date 5/9/05) shows proposed new 24-inch drain pipes apparently connecting to the existing drain in two locations (in the northwest corner and the eastern side of the field) each with invert elevation 7.1. A new unidentified line, not shown on the previous plans, connects to each of the proposed new 24-inch drain pipes. Please identify the new line. 6. Sheet L2.1 (revision date 5/9/05) shows proposed new 15-inch and 24-inch drains in the south and southeast sections of the site, and proposed new 24-inch drains in the northwest corner of the site, all of which were not shown on the previous plans. It appears that each of the proposed new drains will take the place of existing drains on the site. If any existing drain is intended to be taken out of use, ensure that the Contractor performs pipe abandonment work in accordance with City requirements. r05/,.17/2005 08:00 FAX 917812248548 METCALFEDDY 0001/005 .w+ Fax Metcalf & Eddy No. of Pages: 5 Date: May 17,2005 Project No.: J-60001215.00001 To: Frank Taormina From: Mark Meserve Fax No. (978)740-0404 Telephone: (781)224-6094 Company: City of Salem Fax: (781)224-6546 Planning Department Subject: Peer Review of Salem State Alumni Field Renovations Final Letter Report Message: Dear Mr. Taormina: Please find the attached advance copy of the Final Letter Report related to the subject project.Ten copies of the final report will be mailed to you neat-day-delivery for you to receive tomorrow.If this is not acceptable and you also need the hard copies of the report in band today,please let me know.

As a result of these out of scope items, our costs for performing the work will exceed the estimated budget included in our Agreement(Task Order No. 18).We have prepared an amendment to cover the additional estimated costs, for your consideration and for approval by the Owner. Enclosed, for approval by the Owner, are four(4)copies of the proposed Task Order No. 18, Amendment No. 1 and related attachments. Discussion of Scope of Services (Refer to Attachment A-18,Amendment No. 1) Item No. 1.2. Item No. 1.2 identifies specific documents for review. During the course of this Peer review, we reviewed the following additional documents not included in the initial scope of work: • Bid specification section Nos. 02200(Earthwork), 02722 (Storm Drainage System)and 02792 (Infilled Synthetic Turf System)dated March 18, 2005 and April 4, 2005,prepared by Geller DeVellis,Inc. • Geotechnical Investigation Report dated March 4, 2004 prepared by Geotechnical Services, Inc. This additional work is added to the scope of services as shown in italics on Attachment A-18 (Amendment No. 1)subitems 1.2.1 and 1.2.2. Item Nos. 1.3 and 1.4. Item Nos. 1.3 and 1.4 require a review of assumptions made, methodology and design criteria, and calculations representing existing and proposed conditions to verify compliance with the DEP's stormwater management policy and the Wetlands Protection Act, and to render an opinion as to whether the existing drainage system will be negatively impacted. 1 of During the progress of this work,numerous questions arose. Rather than simply continuing the review and documenting the questions for inclusion in the draft letter report,M&E chose to take a more proactive approach and communicated directly with the designer(Geller DeVellis,Inc.)to obtain answers to questions and to"keep the project moving". Metcalf&Eddy took this approach in order to save time, knowing the urgent scheduling issues related to the Project. Thus, M&E communicated extensively with representatives of Geller DeVellis to discuss assumptions made and to request additional information necessary to complete the review. This work included the review of three separate iterations of design calculations submitted to M&E by Geller DeVellis, and numerous conference calls between representatives of M&E and Geller DeVellis to discuss various aspects of the modeling as well as other aspects of the design. Provisions for the communications with representatives of Geller DeVellis, Inc.and the review of interim calculations and other information described above are not included in our initial scope of work. However,we believe these interim communications and review work resulted in substantial savings in time in reaching the ultimate conclusion of our Peer review. The additional work described above is added to the scope of services as shown in italics on Attachment A-18 (Amendment No.1), subitem No. 1.4.1. New Subitem The drainage report and the design drawings have now been revised.Metcalf&Eddy has been asked to review the revised drainage report and the revised design drawings to ensure that all suggested revised work documented in the previous communications are adequately addressed.This additional work is added to the scope of services as shown in italics on Attachment A-18 (Amendment No. 1), subitem 1.5.1. Summary hi conclusion, the additional work described herein reflects an increase of approximately$3,000,bringing the total estimated budget amount to$12,750 as reflected in Task Order No. 18(Amendment No. 1) and in Attachment B-18(Amendment No. 1). During our initial meeting for this project, you were designated as the official point of contact for our communications. Therefore, we request that you forward all four copies of the Amendment to all signatories for execution of page 2 of Task Order No. 18 (Amendment No. 1) and return one executed copy to Metcalf&Eddy.

Discussion of Scope of Services(Refer to Attachment A-18,Amendment No.l) Item No. 1.2. Item No. 1.2 identifies specific documents for review.burring the course of this Peer review,we reviewed the following additional documents not included in the initial scope of work: • Bid specification section Nos.02200(Earthwork),02722(Storm Drainage System)and 02792 (Inli)led Synthetic Turf System)dated March 18,2005 and April 4,2005,prepared by Geller DeVellis,Inc. • Geotechnical Investigation Report dated March 4,2004 prepared by Geotechnical Services,Inc. This additional work is added to the scope of services as shown in italics on Attachment A-18 (Amendment No. 1)subitcros 1.2.1 and 1.2.2. Item Nos. 1.3 and IA. Item Nos. 1.3 and 1.4 require a review of assumptions made,methodology and design criteria,and calculations representing existing and proposed conditions to verify compliance with the DEP's storrnwater management policy and the Wetlands Protection Act,and to render an opinion as to whether the existing drainage system will be negatively impacted. 1 of 2 05/12/2005 14:45 FAX 917812246546 METCALFEDDY 16003/009 During the progress of this work,numerous questions arose.Rather than simply continuing the review and documenting the questions for inclusion in the draft letter report,M&E chose to take a more proactive approach and communicated directly with the designer(Geller DeVellis,Inc.)to obtain answers to questions and to"keep the project moving".Metcalf&Eddy took this approach in order to save time, knowing the urgent scheduling issues related to the Project.Thus,M&E communicated extensively with representatives of Geller DeVellis to discuss assumptions made and to request additional information necessary to complete the review.This work included the review of three separate iterations of design calculations submitted to M&E by Geller DeVellis,and numerous conference calls between representatives of M&E and Geller DeVellis to discuss various aspects of the modeling as well as other aspects of the design. Provisions for the communications with representatives of Geller DeVellis,Inc.and the review of interim calculations and other information described above are not included in our initial scope of work. However,we believe these interim communications and review work resulted in substantial savings in time in reaching the ultimate conclusion of our Peer review.The additional work described above is added to the scope of services as shown in italics on Attachment A-18(Amendment No.1),subitem No. 1.4.1. New Subitem The drainage report and the design drawings have now been revised.Metcalf&Eddy has been asked to review the revised drainage report and the revised design drawings to ensure that all suggested revised work documented in the previous con ummications are adequately addressed.This additional work is added to the scope of services as shown in italics on Attachment A-18(Amendment No. 1),subitem 1.5.1. Summary In conclusion,the additional work described herein reflects an increase of approximately$3,000,bringing the total estimated budget amount to$12,750 as reflected in Task Order No. 18(Amendment No. 1)and in Attachment B-18(Amendment No. 1).During our initial meeting for this project,you were designated as the official point of contact for our communications.Therefore,we request that you forward all four copies of the Amendment to all signatories for execution of page 2 of Task Order No. 18(Amendment No. 1)and return one executed copy to Metcalf&Eddy. If you should have any questions,please do not hesitate to call the writer at(781)224-6094.

Geller stated to Bob that they were a little embarrassed about some of the findings and would like to submit revised documents for M&E's review before a draft report is issued. Bob was instructed that any changes to the peer review would have to be addressed by you as ConCom Clerk/Agent, It was suggested that Bob contact Geller Sport and indicate that Geller needs to speak with their client, Salem State College, to get approval to submit the revised documents and indicate that additional review time would be justified for M&E and therefore another check from the College would be needed for compensation. Additionally, we all know the extremely tight timeline this project is trying to maintain, we, the City, do not want to be blamed for any delays caused by the College's designers. Additionally, there needs to be some documentation of this activity for your files. Based on our conversation regarding this call, please retain this email for your files.

Bruce has asked that I touch base with you since its been some time when the City last heard back from the College and/ or its consultant, Judith Nitsch Engineering, Inc. (JNEI), regarding the outcome of the drainage study being performed by JNEI. As you know, when last the City met with the College's representatives, the preliminary work done by JNEI was very detailed but not yet completed. Now that the College's new athletic field is in use and probably reached substantial completion, it may be a good time to have a meeting on the final results of JNEI's work. The City is looking to secure State funding for design and reconstruction of Canal Street. In order to scope the project appropriately, the various deficiencies, including drainage problems need to be evaluated. As you know with Loring Avenue and the completed athletic field, the sooner design issues are fully vetted, the more comprehensive the design becomes with a better outcome for all involved. In responding, please contact Bruce directly, with a copy to me, since I'm only available on a part-time basis. Thanks, Joseph E.

Item No. 1.2 identifies specific documents for review.During the course of this Peer review, we reviewed the following additional documents not included in the initial scope of work: • Bid specification section Nos.02200(Earthwork),02722 (Storm Drainage System)and 02792 (Infilled Synthetic Turf System)dated March 18,2005 and April 4, 2005,prepared by Geller DeVellis,Inc. • Geotechnical Investigation Report dated March 4, 2004 prepared by Geotechnical Services, Inc. This additional work is added to the scope of services as shown in italics on Attachment A-18 (Amendment No. 1) subitems 1.2.1 and 1.2.2. Item Nos. 1.3 and 1.4. Item Nos. 1.3 and 1.4 require a review of assumptions made, methodology and design criteria, and calculations representing existing and proposed conditions to verify compliance with the DEP's stormwater management policy and the Wetlands Protection Act, and to render an opinion as to whether the existing drainage system will be negatively impacted. 1 of 2 During the progress of this work,numerous questions arose. Rather than simply continuing the review and documenting the questions for inclusion in the draft letter report,M&E chose to take a more proactive approach and communicated directly with the designer(Geller DeVellis,Inc.)to obtain answers to questions and to"keep the project moving".Metcalf&Eddy took this approach in order to save time, knowing the urgent scheduling issues related to the Project. Thus, M&E communicated extensively with representatives of Geller DeVellis to discuss assumptions made and to request additional information necessary to complete the review. This work included the review of three separate iterations of design calculations submitted to M&E by Geller DeVellis, and numerous conference calls between representatives of M&E and Geller DeVellis to discuss various aspects of the modeling as well as other aspects of the design. Provisions for the communications with representatives of Geller DeVellis,Inc. and the review of interim calculations and other information described above are not included in our initial scope of work. However,we believe these interim communications and review work resulted in substantial savings in time in reaching the ultimate conclusion of our Peer review. The additional work described above is added to the scope of services as shown in italics on Attachment A-18 (Amendment No.1), subitem No. 1.4.1. New Subitem The drainage report and the design drawings have now been revised.Metcalf&Eddy has been asked to review the revised drainage report and the revised design drawings to ensure that all suggested revised work documented in the previous communications are adequately addressed.This additional work is added to the scope of services as shown in italics on Attachment A-18 (Amendment No. 1), subitem 1.5.1. Summary In conclusion, the additional work described herein reflects an increase of approximately$3,000,bringing the total estimated budget amount to $12,750 as reflected in Task Order No. 18(Amendment No. 1)and in Attachment B-18 (Amendment No. 1). During our initial meeting for this project,you were designated as the official point of contact for our communications. Therefore,we request that you forward all four copies of the Amendment to all signatories for execution of page 2 of Task Order No. 18 (Amendment No. 1)and return one executed copy to Metcalf&Eddy.

Goal of Peer Review Salem State College proposes to upgrade the Alumni Field by replacing the natural grass surface with a synthetic turf field and a softball field, including a subsurface drainage system (the Project). Salem State College hired various consultants to design the field upgrades and prepare all required regulatory permit application documents,including a Notice of Intent. The Notice of Intent was reviewed by the Salem Conservation Commission,and the resulting Order of Conditions includes a Special Condition requiring a Peer Review prior to the commencement of construction activities. The Peer Review shall include, but not be limited to, a review of the Notice of Intent Application,verify comps-lance with the Massachusetts DEP's Stornwater Management Policy and the Massachusetts Wetlands Protection Act, and render an opinion as to whether the existing off-site drainage system will be negatively impacted as a result of the Project Summary of Documents Reviewed The following documents were reviewed: • Notice of Intent Application dated February 10, 2005 prepared by Epsilon Associates, Inc. • Drainage Report dated February 2005 prepared by Geller DeVellis, Inc. 1 of 3 05/17/2005 08:23 FAX 917812246546 METCALFEDDY �� • Drainage Report dated February 2005,revised May 2005 prepared by Geller DeVellis, Inc. • Design plans prepared by various consultants entitled"Notice of Intent.

Summary of Recent SubmHtals Metcalf&Eddy submitted a Draft Letter Report to the Planning Department on May 3,2005, The Draft Letter Report contained a number of review comments for consideration Many of the review comments,if implemented, required changes to the Drainage Report,design plans and specifications. Subsequently, Metcalf&Eddy received from Geller DeVellis a copy of a revised Drainage Report(dated May 2005),a set of revised design drawings (dated May 9, 2005), a revised specification section 02722(Storm Drainage System)and a transmittal letter addressed to the Conservation Commission dated May 11. 2()05. Compliance with Stormwater Management Policy and Wetlands Protection Act We have reviewed all of the revised documents and find that all comments related to the Stormwater Management Policy and Wetlands Protection Act have been addressed.Therefore, it is our opinion that the overall project design and related documents are in compliance with the Stormvater Management Policy and Wetlands Protection Act Impacts to Existing Drainage System The results of the revised modeling show that the estimated future(post-construction)peak flows for the 2, 10 and IOD-year storms and the total volume for the 100-year storm will not 2of3 05/17/2005 08:23 FAX 917812246546 METCALFEUDY increase as a result of Project implementation.Therefore, it is our opinion that the wasting off- site drainage system will not be adversely impacted after construction of the proposed Alumni Field renovations. Addltional Review Comments The Draft Letter Report contained a document entitled`Attachment B°which identified additional miscellaneous review comments that,although not specifically related to the Stomwvater Management Policy or the Wetlands Protection Act, never-the-less may affect the overall design intent.We have found that most of the review comments contained in Attachment B of the Draft Letter Report have been addressed,either in the revised design drawings or specification section 02722. However,presented in Attachment A are additional miscellaneous review comments related to the revised design drawings.We suggest that these comments be addressed during the earty stages of construction. Revised documents addressing these comments do not need to be submitted to Metcalf&Eddy. Should you have any questions or ff you would like to schedule a meeting to review the comments included herein, please do not hesitate to contact the writer at(781)224.6094. Very truly yours.

Notes requiring verification of the elevations of the existing pipe at proposed pipe crossings were added at two locations, but not in the location suggested in the Draft Report,Attachment B, item 5. Prior to construction, please also confirm the elevation of the existing 30-inch sewer where it crosses the proposed 12-inch diameter perforated drain on the west side of the site. 2. The designer has confirmed that a butterfly valve Will be installed at each of the two discharge locations.Although the Draft Letter Report suggests a butterfly valve, other valve types, such as a ball valve,are acceptable at these locations, as determined by the designer. During the shop drawing review process, the Contractor should submit information related to operation and maintenance for the valves, and this material shall become the property of the City upon the completion of the work. 3. Sheet SP1.1 (revision date 5/9/05)requires protection of an existing drain manhole in the northwest comer of the site. However, sheet L2.1 (revision date 5/9/05) requires the same drain manhole to be removed.This apparent discrepancy should be resolved. 4. Sheet L2.1 (revision date 5/9105)shows a proposed additional new sewer pipe that is not shown on the Sheet L2.1 initially reviewed as part of the Draft Letter Report. For the proposed new sewer identified as "Part of Alternate#2"in the southeast comer of the site, identify the sewer size and pipe type. If the existing sewer between each end of the proposed sewer is to be abandoned, ensure that the Contractor performs pipe abandonment work in accordance with City requirements. 5. Sheet L2.1 (revision date 5/9/05)shows proposed new 24-inch drain pipes apparently connecting to the existing drain in two locations (in the northwest comer and the eastern sloe of the field)each with invert elevation 7.1. A new unidentified line, not shown on the previous pians,connects to each of the proposed new 24-inch drain pipes. Please identify the new line. 6. Sheet L2.1 (revision date 5/95)shows proposed new 15-inch and 24-inch drains in the south and southeast sections of the site, and proposed new 24-inch drains in the northwest corner of the site, all of which were not shown on the previous plans. It appears that each of the proposed new drains will take the place of existing drains on the site. If any existing drain is intended to be taken out of use, ensure that the Contractor performs pipe abandonment work in accordance .J/ with City requirements. f 1 7, �d M�- ie c M /b ro 7�G41r-" C*, �A G E L L E R D E V E L LIS 11 May 2005 Mr. Frank Taormina Conservation Agent City of Salem City Hall Annex 120 Washington Street Salem, Massachusetts 01970 Re: Revised Drainage Report and Project Plans Dear Mr. Taoromina: Please find enclosed a the revised Drainage Report dated March 2005, Revised May 2005, a revised set of Project Plans dated February 10, 2005, revised May 9, 2005, and a revised section 02722 Storm Drainage Piping from the Project Specifications.

ATTACHMENT A- PROJECT NARRATIVE 1.0 Introduction On behalf of Salem State College (the "Applicant"), Epsilon Associates, Inc. is pleased to submit this Notice of Intent (NOI") application to the Salem Conservation Commission ("SCC'), for turf renovations and related improvements to Alumni Field which is located adjacent to the O'Keefe Athletic Center and the Richard H. Rocket ice arena at 225 Canal Street in Salem, Ma (see Figure 1, USGS Locus Map). This NOI has been prepared in accordance with the Massachusetts Wetland Protection Act (MGL c.131 s.40) and implementing Regulations(310 CMR 10.00)(the"Act"). The majority of the project will occur beyond the 100 foot buffer zone of an isolated vegetated wetland and no wetland impacts are proposed or anticipated. The following project elements(ora portion thereof)will occur in the 100 foot buffer zone: 1. The existing grass turf at Alumni Field will be replaced and reconfigured with a low maintenance in-filled synthetic turf system. Unlike the existing grass field, the in- filled synthetic turf system will not require irrigation or treatment with pesticides, fertilizers and/or herbicides. 2. A perforated underdrain system will be installed beneath the in-filled synthetic turf allowing it to drain properly into the existing stormwater management system and provide a degree of groundwater recharge. 3. Existing municipal drain lines located beneath the field may be replaced in-kind. A final decision will made after Salem State College and the Salem Engineering Department have had an opportunity to inspect the condition of the pipes. This inspection work is ongoing. 4. A section of existing chain link fence will be removed and replaced with a new eight foot high chain link fence located slightly up gradient and to the west of the delineated wetland edge. 5. Construction of an approximately 3 foot high modular concrete retaining wall and turf anchor system. 6. Three light poles,and; 7. Minor landscaping improvements (evergreens,shrubs, loam and seed,stone dust). Salem State College—Alumni Field 1 Attachment A-Narrative Epsilon Associates,Inc. Insert Figure 1, USGS Locus Map Salem State College—Alumni Field 2 Attachment A-Narrative Epsilon Associates,Inc. Related improvements which are not located in the 100 foot buffer zone include: 1. An existing stand of bleachers, scoreboard and related utility connections will be removed and replaced with a dugout, portable bleachers, walkways and appurtenant utility connections 2. The northern end of the existing athletic field will be reconfigured to accommodate a softball field. 3. Minor modifications to the existing stormwater management system including sawcuts to the existing pavement and the removal of certain catch basins (see attached Stormwater Management Report prepared by Geller Associates, Inc. for additional detail), 2.0 Existing Conditions Alumni Field is located adjacent to the O'Keefe Center and Richard H. Rocket ice arena. The approximately 2.8 acre site is situated between Day Avenue,Atlantic Street and Pacific Street. Residential dwellings generally exist to the north, east and south. A large surface parking lot exists to the northwest. Except for the existing turf athlaic field,the majority of the project site is devoid of vegetation and otherwise occupied by impervious surfaces associated with existing buildings and pavement. A small vegetated wetland was identified and delineated by project scientists(see project site plans). This wetland resource area may be isolated as there was no evidence of a perennial or intermittent stream channel or other surface water body. Notwithstanding, for the purposes of this NOI, the Applicant has conservatively identified the wetland as a bordering vegetated wetland per 310 CMR 10.55 (see Section 3.0 below for additional detail). The wetland is noticeably degraded, comprised of fill material and invasive plant species (primarily Phragmites spp.). Stormwater runoff from Pacific Street discharges directly into this wetland via an existing headwall and culvert located near wetland flag 1-1. An existing 30-inch corrugated metal pipe near wetland flag 16 conveys eater from this wetland, beneath the existing athletic field and into a catch basin located on the above referenced surface parking lot. 3.0 Wetland Resource Areas Project scientists identified one isolated vegetated wetland (referred to as Wetland #1) within 100 feet of proposed work (see Figure 2 and project site plans). As mentioned above, this wetland may not be subject to protection as a bordering vegetated wetland per 310 CMR 10.55 but has nonetheless been depicted conservatively as a jurisdictional resource area on project site plans. Wetland #1 was delineated in accordance with the Massachusetts Department of Environmental Protection (DEP) handbook, 'Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act' (DEP, 1995), and the US Army Corps of Engineers "Wetland Delineation Manual" (ACOE, 1987). Wetland #1 consists of fourteen flags labeled 1-1 through 1-14. Salem State College-Alumni Field 3 Attachment A-Narrative Epsilon Associates,Inc. Insert figure 2 Salem State College—Alumni Field 4 Attachment A-Narrative Epsilon Associates,Inc. The edge of Wetland #1 is very well defined on all sides by manicured lawns, fill material and an existing chain link fence. Invasive common reed(Phragmites australis and common cattail (Typha spp.) are the predominant cover type;. While certain activities will occur in the 100 foot buffer zone,the Project does not propose any temporary or permanent impacts to this wetland resource area. The Massachusetts Natural Heritage and Endangered Species Atlas(MassG IS 2003)does not identify an area of estimated habitat, certified vernal pools or potential vernal pools on or near the project site Lastly, according to the applicable Flood Insurance Rate Map (FIRM) provided through MassGIS 2003, the site is not located within a jurisdictional flood hazard area (i.e., Zone A -100 year floodplainbordering land subject to flooding). 4.0 Proposed Renovations and Improvements Project elements occurring in the 100 foot buffer zone are described below. Wetland impacts are not proposed or anticipated. Multi-Purpose Athletic Field The existing turf at Alumni Field will be replacedand reconfigured with a low maintenance in-filled synthetic turf system. The new field will comply with NCAA design requirements and will be used by Salem State College forsoccer,field hockey and softball. The proposed softball field will be located entirely outside of the buffer zone except for a small section of bullpen along the proposed left field line (see Sheet 11.1 in the attached drawing set).The bullpen will be comprised of a typical soil infield mix. Unlike the existing grass field,the in-filled synthetic turf systen will not require irrigation or treatment with pesticides, fertilizers and/or herbicides. As depicted on Sheet L4.1 on the attached drawing set, he existing turf field will be excavated to a depth of approximately one foot and replaced with approximately nD e fool Deleted: we of layered in-filled materia The in-filled material will be retained with an approximately Deleted:ee three foot high modular concrete retaining wall and anchor system constructed around the Deleted: (Ihegradeonhenewfield perimeter of the athletic field limits.

A perforated undercut in system will be installed beneath the in-filled synthetic turf allowing it to drain properly and provide a nominal degree of groundwater recharge. As depicted on the detail sheet included in the attached plan set,the underdrain system will consist of four subsurface layers consisting of a compacted subgrade, geotextile fabric (woven/unwoven), crushed stone base,and a free draining choker layer. The perforated underdrain piping will be placed at the base of the third layer, (crushed stone base) and willbe located at approximately twenty foot intervals extending across the field. In-filled synthetic turf will be secured above these layers and anchored at several locations. Runoff from the athletic fields will be minimal, as the drainage system described above is designed to allow maximum infiltration of stormwater, while also collecting ground and surface water from surrounding pervious and impervious surfaces. A collector pipe constructed around the perimeter of the field will convey runoff into the existing catch basin system in the surface parking lot located just northwest of the athletic field.

Stormwater Management System Modifications The existing stormwater management system will largely remain untouched except for the removal of three catch basins and associated piping located beyond the 100 foot buffer zone (see Sheet SP1.1). Existing municipal drain lines located beneath the field may be replaced in-kind pending additional inspections(via a video camera placed in the pipes)by Salem State College and the Salem Engineering Department. These pipes are currently labeled"protected"on Sheet SP1.1. The project will result in improved water quality while maintaining comparable pre- development and post-development runoff rates. The post development watershed substantially mimics the pre-development watershed. Please refer to the attached stormwater management report for additional detail. Salem State College-Alumni Field 6 Attachment A-Narrative Epsilon Associates, Inc. 5.0 Mitigation Measures An erosion and sediment control program will minimize the risk of impacts to wetland resource areas during the construction of the project. Sedimentation and erosion control details are provided on Sheet SP1.1. Siltation barriers comprised of double-staked hay bales and trenched silt fence will be installed up-gradient of Wetland #1 immediately behind the existing chain link fence. Existing catch basins will also be protected by a staked haybale barrier. All barriers will remain in place until disturbed areas are stabilized by vegetation and/or the up gradient retaining wall construction is complete. 6.0 Conclusions The project as proposed will not adversely impact wetland resource areas protected under the Massachusetts Wetland Protection Act. The ability of on-site wetland resource areas to provide those interests presumed significant under the Act are not impaired including the ability to provide:flood control,storm damage prevention, protection of public and private water supplies, protection of groundwater, wildlife habitat, fisheries habitat, and pollution attenuation. 7.0 Literature Cited DEP, 1995.

The proposed upgrade will also include new concrete walkways and pads, fencing, retaining walls, athletic lighting, utility services and drainage improvements. Construction of the proposed project is subject to the Massachusetts Department of ■_ Environmental Protection Stormwater Management Policy (March 1997). The project will comply with the nine standards referenced in this publication and will satisfy ■ regulatory requirements set forth by MADEP and the MA Wetlands Protection Act. ■ The proposed drainage system is designed to maintain the characteristics of the existing ■ watershed areas to the extent practicable. Runoff rates at the discharge point will be maintained at or below existing levels with the addition of a retention area located in the ■ subsurface drainage system of the new infilled synthetic turf athletic field. li ■ The following is a brief description of the existing and proposed drainage areas and design methodology for this project. ■ ■ ■ ■ ■ ■ Geller DeVellis Inc. ■ a gI Conditions Exton a � a Existing Site Characteristics The project site is located at Alumni Field at Salem State College in Salem, ■ Massachusetts (see Figure 1). The field is currently a natural grass athletic field used by the school in the fall and spring. The field is pitched to drain towards catch basins and towards a wetland creating the two watersheds described below. Eventually these two watersheds combine in the existing stormwater drainage system and leave the site, but for the purpose of this analysis the watersheds will be treated as two separate entities. Description of Contributing Area The existing site contains two drainage areas (see Figure 2) that will be affected by ■ the proposed improvements. For the purpose of this hydrologic analysis, the following assumptions were made: ■ • Whenever possible, the fence line and/or an arbitrary line, outside the limit of proposed work is delineated as the watershed boundary. • The total watershed area for the existing conditions is used as the comparison base for the watershed area in the proposed conditions. a The following is a brief description of the drainage areas: ■ ■ Drainage Area EX-1 ■ Drainage Area EX-1 is approximately 2.43-acres. The watershed is made up of part of the natural grass athletic field, some hedge and mulch areas, the bleachers sitting on a bituminous concrete pad and walkways within the area. Stormwater runoff from this area is collected in a series of catch basins and enters the existing stormwater drainage system which goes towards the existing parking lot to the north of the field(Discharge Point 1). Drainage Area EX-2 M Drainage Area EX-2 is approximately 0.80-acres. The watershed is made up of the remaining natural grass athletic field area, hedge and mulch areas and bleachers M sitting on soil. Stormwater runoff from this area drains towards the existing wetland at the south end of the site (Discharge Point 2). ,M M M 1 Existing Conditions a ■ } , IiFTPIP �� j.11�4� � ell 14 fi'4 ' w 1'�.r �' � `lei' .� p -x�J� ''3a€F�°� •,;S ' oq'4��st�",�y'—�� x ' R IE * -•, "wim � 1� gaga, , r ,.: '' ► 6 � .

The existing bleachers and bituminous concrete will be removed from the field with the addition of a concrete ■ walk and drive, two new concrete bleacher pads outside the field area and concrete softball team areas. Retaining walls will be used at the east corner of the site to meet ■ the foul pole distances required by the National Collegiate Athletic Association ■ (NCAA) for softball. ■ The proposed drainage system is designed to maintain the characteristics of the existing watershed areas to the extent practicable. Runoff rates at the discharge ■ point will be maintained at or below existing levels with the addition of a retention area located in the subsurface drainage system of the new infilled synthetic turf ■ athletic field. ■ The retention system developed using the subbase of the infilled synthetic turf system is comprised of 1/4" stone, which has a void ration of 0.4, and flat drain pipes ■ which have a cross-sectional area equivalent to a 4" diameter pipe. Water is retained within the field using an outlet control manhole, which causes the system to backup ■ into the subbase and then allows water out at a controlled rate to meet the existing conditions of the site. ■ ■ Description of ContributingAreas ■ The proposed site contains two drainage areas (see Figure 3). The following is a brief description of these drainage areas. ■ Drainage Area PR-1 ■ Drainage Area PR-1 is approximately 2.46-acres. The area is broken up into a ■ detained area, PR-IA, and a non-detained area, PRAB. All of the runoff from this area leaves the site by entering the existing storm water drainage system outside the ■ limit of work. ■ Drainage Area PR-IA is approximately 1.87-acres consisting of approximately seventy-percent of the infilled synthetic turf field, some impervious pavement and ■ grass and hedge areas. The runoff from this area will be detained within the subsurface drainage system of the infilled synthetic turf field. Runoff will be ■ released at a controlled rate back into the existing stormwater system. ■ Drainage Area PR-1B is approximately 0.59-acres consisting of the softball infield, ■ some impervious walkways and some grass and hedge areas. Runoff enters the existing stormwater system through a proposed catch basin without being detained. ■ �a 1 Proposed Conditions ■ ■ ■ ■ ■ ■ LEGEND ■ -R♦Dp-1 D/sryARGE PdNr ® _ — 1 ORA/NAGE AREA ■ --------- WA7ERS7ED BOUNDARYt— ■ �&OFF—F /..

Inc. -2- 10 February 2005 ■ ■ Operation and Maintenance Plan Source Control The first tier of non-structural controls includes a comprehensive source control program of regular sweeping and maintenance of the storm water system. Pavement Sweeping Program ■ While certain types of street sweepers are not effective for the removal of fine particulates and pollutants associated with them, most are quite effective for the removal of large quantities of sand, grit, and assorted inorganic and organic debris. Larger material carried in storm water poses an environmental threat not only by degrading aesthetics, but may also contribute pollutants as it degrades over time. In addition, larger materials may clog conveyance systems, reduce the efficiency and longevity of treatment systems and ultimately result in more maintenance downstream. The removal of contaminants directly from paved surfaces before contact with storm water is a valuable method for reducing pollutant loading in storm water. It is proposed that the walk areas will be swept on a semi-annual basis, with at least two sweepings per year. Sweeping at the end of the winter season will be encouraged as during the winter sand which typically migrates to the edges of paved areas will need to be removed. Catch Basins New catch basins at the site will be equipped with deep sumps and hooded outlets to trap debris, sediments and floating contaminants, which are the largest constituents of urban runoff. Catch basins will be cleaned twice per year. This practice in coordination with minimal use of sand and street sweeping comprises a multi-level source control approach that prevents sand/sediments and litter from exiting off-site and/or ultimately into the resource areas. .

Rocket ice arena at 225 Canal Street in Salem, Ma (see Figure 1, USGS Locus Map). This NOI has been prepared in ' accordance with the Massachusetts Wetland Protection Act (MGL c.131 s.40) and implementing Regulations (310 CMR 10.00) (the "Act"). The majority of the project will occur beyond the 100 foot buffer zone of an isolated vegetated wetland and no wetland impacts are proposed or anticipated. The following project elements (or a portion thereof) will occur in the 100 foot buffer zone: 1. The existing grass turf at Alumni Field will be replaced and reconfigured with a low maintenance in-filled synthetic turf system. Unlike the existing grass field, the in- filled synthetic turf system will not require irrigation or treatment with pesticides, fertilizers and/or herbicides. 2. A perforated underdrain system will be installed beneath the in-filled synthetic turf allowing it to drain properly into the existing stormwater management system and provide a degree of groundwater recharge. 3. Existing municipal drain lines located beneath the field may be replaced in-kind. A final decision will made after Salem State College and the Salem Engineering Department have had an opportunity to inspect the condition of the pipes. This ` inspection work is ongoing. 4. A section of existing chain link fence will be removed and replaced with a new eight foot high chain link fence located slightly up gradient and to the west of.the delineated wetland edge. 5. Construction of an approximately 3 foot high modular concrete retaining wall and turf anchor system. 6. Three light poles, and; 7. Minor landscaping improvements (evergreens, shrubs, loam and seed, stone dust). 5alem State College-Alumni Field I Attachment -Narrative Epsilon Associates, Inc.

G:lPmjects21MAISalemll27603Umus—usgs.mxd 01105105 Related improvements which are not located in the 100 foot buffer zone include: r1. An existing stand of bleachers, scoreboard and related utility connections will be removed and replaced with a dugout, portable bleachers, walkways and ' appurtenant utility connections 2. The northern end of the existing athletic field will be re-configured to accommodate ' a softball field. 3. Minor modifications to the existing stormwater management system including sawcuts to the existing pavement and the removal of certain catch basins (see attached Stormwater Management Report prepared by Geller Associates, Inc. for additional detail). ' 2.0 Existing Conditions ' Alumni Field is located adjacent to the O'Keefe Center and. Richard H. Rocket ice arena. The approximately 2.8 acre site is situated between Day Avenue, Atlantic Street and Pacific ' Street. Residential dwellings generally exist to the north, east and south. A large surface parking lot exists to the northwest. Except for the existing turf athletic field, the majority of the project site is devoid of vegetation and otherwise occupied by impervious surfaces ' associated with existing buildings and pavement. A small vegetated wetland was identified and delineated by project scientists (see project site plans). This wetland resource area may be isolated as there was no evidence of a perennial or intermittent stream channel or other ' surface water body. Notwithstanding, for the purposes of this NOI, the Applicant has codservatively identified the wetland as a bordering vegetated wetland per 310 CMR 10.55 (see Section 3.0 below for additional detail). The wetland is noticeably degraded, ' comprised of fill material and invasive plant species (primarily Phragmites spp.). Stormwater runoff from Pacific Street discharges directly into this wetland via an existing ' headwall and culvert located near wetland flag 1-1. An existing 30-inch corrugated metal pipe near wetland flag 1-6 conveys water from this wetland, beneath the existing athletic field and into a catch basin located on the above referenced surface parking lot. ' 3.0 Wetland Resource Areas Project scientists identified one isolated vegetated wetland (referred to as Wetland #1) within 100 feet of proposed work (see Figure 2 and project site plans). As mentioned above, this wetland may not be subject to protection as a bordering vegetated wetland per ' 310 CMR 10.55 but has nonetheless been depicted conservatively as a jurisdictional resource area on project site plans. Wetland #1 was delineated in accordance with the Massachusetts Department of Environmental Protection (DEP) handbook, "Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act' (DEP, 1995), and the US Army Corps of Engineers "Wetland Delineation Manual' (ACOE, 1987). ' Wetland #1 consists of fourteen flags labeled 1-1 through 1-14.

Wetlands Resources, 250 0 250 500 Salem State College _ The edge of Wetland #1 is very well defined on all sides by manicured lawns, fill material and an existing chain link fence. Invasive common reed (Phragmitesaustralis) and common cattail (Typha spp.)are the predominant cover types. While certain activities will occur in the 100 foot buffer zone, the Project does not propose any temporary or permanent impacts ' to this wetland resource area. The Massachusetts Natural Heritage and Endangered Species Atlas(MassG IS 2003) does not ' identify an area of estimated habitat, certified vernal pools or potential vernal pools on or near the project site. Lastly, according to the applicable Flood Insurance Rate Map (FIRM) provided through MassGIS 2003, the site is not located within a jurisdictional flood hazard area (i.e., Zone A ' - 100 year floodplain/bordering land subject to flooding). 4.0 Proposed Renovations and Improvements Project elements occurring in the 100 foot buffer zone are described below. Wetland impacts are not proposed or anticipated. ' Multi-Purpose Athletic Field ' The existing turf at Alumni Field will be replaced and reconfigured with a low maintenance in-filled synthetic turf system. The new field will comply with NCAA design requirements and will be used by Salem State College for soccer, field hockey and softball. The proposed ' softball field will be located entirely outside of the buffer zone except for a small section of bullpen along the proposed left field line (see Sheet 1-1.1 in the attached drawing set). The bullpen will be comprised of a typical soil infield mix. Unlike the existing grass field, the ' in-filled synthetic turf system will not require irrigation or treatment with pesticides, fertilizers and/or herbicides. As depicted on Sheet L4.1 on the attached drawing set, the existing turf field will be excavated to a depth of approximately one foot and replaced with approximately two feet ' of layered in-filled material (the grade of the new field will therefore be approximately one foot higher than the grade of the existing field). The in-filled material will be retained with an approximately three foot high modular concrete retaining wall and anchor system ' constructed around.the perimeter of the athletic field limits. At its closest point, the proposed modular retaining wall be located approximately five feet from the delineated wetland (see Sheet 1-1.1). In conjunction with retaining wall construction and the ' installation of sedimentation and erosion control devices, the existing chain link fence will be removed from this location and re-installed on top of the modular retaining wall slightly ' up gradient from the BVW edge. Salem State College-Alumni Field 5 Attachment A -Narrative ' Epsilon Associates, Inc. r Perforated Underdrain System ' A perforated underdrain system will be installed beneath the in-filled synthetic turf allowing it to drain properly and provide a nominal degree of groundwater recharge. As depicted on r the detail sheet included in the attached plan set, the underdrain system will consist of four subsurface layers consisting of a compacted subgrade,geotextile fabric (woven/unwoven), crushed stone base, and a free draining choker layer. The perforated underdrain piping will rbe placed at the base of the third layer, (crushed stone base) and will be located at approximately twenty foot intervals extending across the field. In-filled synthetic turf will be ' secured above these layers and anchored at several locations. Runoff from the athletic fields will be minimal, as the drainage system described above is r designed to allow maximum infiltration of stormwater, while also collecting ground and surface water from surrounding pervious and impervious surfaces. A collector pipe constructed around the perimeter of the field will convey runoff into the existing catch ' basin system in the surface parking lot located just northwest of the athletic field. Refer to the attached Stormwater Management Report and Sheet L2.1 entitled "Grading and Utility Plan" in the attached drawing set for additional detail. rLighting and Utilities rUtility improvements in the buffer zone are minor and include the replacement of three light poles and the extension of a water line to the softball field dugout. Refer to Sheet L2.1 entitled "Grading and Utility Plan" in the attached drawing set for additional detail. Minor Landscaping Improvements ' Landscaping improvements will also be minor and will consist of a variety of evergreens, shrubs, loam and seed, and stone dust. Refer to Sheet L3.1 entitled "Planting Plan" in the rattached drawing set for additional detail. Stormwater Management System Modifications The existing stormwater management system will largely remain untouched except for the removal of three catch basins and associated piping located beyond the 100 foot buffer r zone (see Sheet SPLA). Existing municipal drain lines located beneath the field may be replaced in-kind pending additional inspections (via a video camera placed in the pipes) by Salem State College and the Salem Engineering Department. These pipes are currently rlabeled "protected" on Sheet SPI.t. The project will result in improved water quality while maintaining comparable pre- ', r development and post-development runoff rates. The post development watershed substantially mimics the pre-development watershed. Please refer to the attached rstormwater management report for additional detail. Salem State College-Alumni Field 6 AttachmentA -Narrative rEpsilon Associates, Inc. 5.0 Mitigation Measures An erosion and sediment control program will minimize the risk,of impacts to wetland resource areas during the construction of the project. Sedimentation and erosion control details are provided on Sheet SPI.1. Siltation barriers comprised of double-staked hay bales and trenched silt fence will be installed up-gradient of Wetland #1 immediately behind the existing chain link fence.
