The only two changes to this plan are the addition of a note regarding the maintenance of the landscaping, and the addition of additional lights and a cut sheet on the proposed lights. The note was added on the right portion of the plan below the other notes. Also, please find enclosed a copy of the proposed lighting plan for this site plan, which was requested at the Public Hearing. I apologize regarding the lighting plan. At the time of the Public hearing I thought they were going to use the two existing lights. However, I found out after the meeting that they are planning to install far superior, LED lights. Please find enclosed three copies of our site plan and three copies of the lighting plan. If you require any additional information please contact me.

Erosioo & SedementotiQn Control Notes 1. The contractor and all sub-contractors are to be made aware that on Order of Conditions may be required from the Agawam Conservation Commission. A copy of the Order is to be readily available on site ot all times. DEP File # sign is to be posted. 2. Staked hoy bales and silt fences are to be installed where shown on this plan. The contractor and the owner are responsible for the proper maintenance of the hay bole dike and to Identify and correct all saurces of erosion. Extra hay bales are to be stored on site in order to quickly repair erosion prone areas. Periodic maintenance af the erosion control structures is required in order to insure the proper protection of the resource areas. 3. Rough grading and pavement construction are to be confined to the areas shown on this plan. Construction materials are to be stockpiled within existing developed areas. Top soil stockpiles shall be surrounded with sUt fence and. if not required for use within 14 days, stabilized with temporary seed and mulch. The recommended temporary seed is Rye (grcin). 4. At no time should heavy eqUipment crass the hay bale dike or operate within any resource area. All fueling of construction equipment is to be done outside of the buffer zone. 5. Temporary stabilization of disturbed areas is required to limit erosion toward wetlands or existing storm water management areas. All groded slopes ore to be stabilized on a daily basis with special care token ta ovoid routing rainfall through gullies toward the wetland areas. Areas af erosion are to be repaired on a doily basis. 6. The contractor is to use proper ):Jdgment relative ta construction practices during adverse weather conditions or periods of high groundwater. No work is to be performed near the resource areas during periods of heavy rainfall. Inspection is required after more than 1/2" of rainfall In 24 hours. 7. All graded areas are to be loomed and seeded as soon as possible in order to insure the rapid stabilization of the erosion prone areas. A grass seed mixture of 20% Red Top, 60% Chewings Fescue and 20% Kentucky Bluegrass Is recommended, "Hydroseed" with high fiber content. 8. The Staked Hay Bole Dikes are to remain in place for at least one full growing season. Periodic inspections of these erosion control structures is to continue during this phase of vegetation stabilization. In areas where silt fences have been installed, they ore to be removed once the slopes have been stabilized in order to promote migration of local amphibious species. 9. During periods of heavy rainfall, it will be expected to experience erosion of the unstabilized slopes. Immediate attention to the maintenance of these eroded areas will further insure the successful stabilization of the exposed slopes while limiting the impacts to nearby wetlands. 10. Periodic inspections of the entire construction site are to be perfarmed by a competent representative who will insure the odherence to the regulations as set forth in 310 CMR 10,00. No unauthorized Indlvfduals are to enter the construction area without the expressed consent of the owner. 11 . The contractor will ensure that no runoff enters the infiltration trenches until all building construction Is completed and the proposed parking and driveway areas are paved. 12. Inspect and clean sediment foreboys upon completion of construc tion. Note: All plantings must be maintained and that portion of the public way abutting the parcel and including the treebelt shall be maintained in a safe and attractive condition by the owner of the parcel. proposed light see sheet 4 for specifications Site Plan for Parking Expansion Located At Heritage Woods Agawam, MA Owned by Genesis Health Ventures of Massachusetts, Inc. 415 McFarlan Rd, Suite 202 Kennett Square, PA 19348 August 9, 2011 Scale: 1"=20' REVISIONS NO.

I~ ~ I I I I I I I I I I I I Massachusetts Department of Environmental Protection Bureau of Resource Protection -Wetlands Program Checklist for Stormwater Report A. Introduction A Stormwater Report must be submitted with the Notice of Intent permit application to document compliance with the Stormwater Management Standards. The following checklist is NOT a substitute for the Stormwater Report (which should provide more substantive and detailed information) but is offered here as a tool to help the applicant organize their Stormwater Management documentation for their Report and for the reviewer to assess this information in a consistent format. As noted in the Checklist, the Stormwater Report must contain the engineering computations and supporting information set forth in Volume 3 of the Massachusetts Storrnwater Handbook. The Stormwater Report must be prepared and certified by a Registered Professional Engineer (RPE) licensed in the Commonwealth. The Stormwater Report must include: • The Stormwater Checklist completed and stamped by a Registered Professional Engineer (see page 2) that certifieS that the Stormwater Report contains all required submittals.' This Checklist is to be used as the cover for the completed Stormwater Report. • Applicant/Project Name • Project Address • Name of Firm and Registered Professional Engineer that prepared the Report • Long-Term Pollution Prevention Plan required by Standards 4-6 • Construction Period Pollution Prevention and Erosion and Sedimentation Control Plan required by Standard 8' • Operation and Maintenance Plan required by Standard 9 In addition to all plans and supporting information, the Stormwater Report must include a brief narrative describing stormwater management practices, including environmentally sensitive site design and LID techniques, along with a diagram depicting runoff through the proposed BMP treatment train. Plans are required to show existing and proposed conditions, identify all wetland resource areas, NRCS soil types, critical areas, Land Uses with Higher Potential Pollutant Loads (LUHPPL), and any areas on the site where infiltration rate is greater than 2.4 inches per hour. The Plans shall identify the drainage areas for both existing and proposed conditions at a scale that enables verification of supporting calculations. As noted in the Checklist, the Stormwater Management Report shall document compliance with each of the Stormwater Management Standards as provided in the Massachusetts Stormwater Handbook. The soils evaluation and calculations shall be done using the methodologies set forth in Volume 3 of the Massachusetts Stormwater Handbook. that the Stormwater Report is complete, applicants are required to fill in the Stormwater Report Checklist by checking the box to indicate that the speCified information has been included in the Stormwater Report. If any of the information specified in the checklist has not been submitted, the applicant must provide an explanation. The completed Stormwater Report Checklist and Certification must be submitted with the • The Stonnwater Report may also include tho Illcll Discharge Compliance Stalemenl required by Standard 10. H nol included in the Stonnwater Report, the IlIic~ Discharge Compliance Sialement must be submitted prior 10 the discharge 01 slonnwater runof! 10 the post-construction best management practices. 2 For some complex projects, it may not be possible to include the Construction Period Erosion and sedimentation Control Plan in the Stormwater Report. In that event, the issuing authority has the discretion to issue an Order of Conditions that approves the project and includes a condition requiring the proponent to submit the Construction Period Erosion and Sedimentation Control Plan before commencing any land disturbance activ~ on Ihe site.

Stormwater Checklist and Certification The following checklist is intended to serve as a guide for applicants as to the elements that ordinarily need to be addressed in a complete Stormwater Report. The checklist is also intended to provide conservation commissions and other reviewing authorities with a summary of the components necessary for a comprehensive Stormwater Report that addresses the ten Stormwater Standards. Note: Because stormwater requirements vary from project to project, it is possible that a complete Stormwater Report may not include information on some of the subjects specified in the Checklist. If it is determined that a specific item does not apply to the project under review, please note that the item is not applicable (N.A.) and provide the reasons for that determination. A complete checklist must include the Certification set forth below signed by the Registered Professional Engineer who prepared the Stormwater Report. Registered Professional Engineer's Certification I have reviewed the Stormwater Report, including the soil evaluation, computations, Long-term Pollution Prevention Plan, the Construction Period Erosion and Sedimentation Control Plan (if included), the Long- term Post-Construction Operation and Maintenance Plan, the Illicit Discharge Compliance Statement (if included) and the plans showing the stormwater management system, and have determined that they have been prepared in accordance with the requirements of the Stormwater Management Standards as further elaborated by the Massachusetts Stormwater Handbook. I have also determined that the information presented in the Stormwater Checklist is accurate and that the information presented in the Stormwater Report accurately reflects conditions at the site as of the date of this permit application.

Presently, there is a nursing home and parking lot on the property. Ground cover within the construction area is 37% impervious with the remaining 63% of the property being turf grass. Stormwater run-off from the construction area flows southerly across the site to a stomwater management system shared with the abutting parcel to the south. The soils within the site have been classified by the NRCS as Wareham loamy sand and Enfield silt loam. Soil tests performed by Land Planning, Inc. demonstrate that all of the soils within the construction area are of the Wareham type. Wareham soil belongs to hydrologic soil group C. Testing performed by Land Plarming indicate that the soils C horizon is sand with high groundwater. The soils are highly permeable and suitable for infiltration and groundwater recharge. DEVELOPED CONDITIONS: Development plans for the site include the expansion of the parking lot providing 33 additional parking spaces. The remaining open areas of the construction limits will consist oflawn and a constructed stormwater wetland. Increased run-off rates as a result of development will be attenuated through the stormwater wetland. ANALYSIS: The goal of the stormwater management system proposed is to ensure that there is no significant increase in peak run-off rates downstream of the site. This goal is achieved through directing the run-off from the proposed parking expansion to the stormwater wetland and infiltration trenches. CALCULATIONS: Stormwater modeling was performed using Hydrocad version 7. SUMMARY: 2 Year 10 Year 100 Year Pre Post Pre Post Pre Post 1.77 1.74 3.30 3.26 5.76 5.63 Table 1 (cfs) CONCLUSIONS: From this analysis we conclude that no increase in peak run-off rates will occur off-site for the 2, 10, and 100 year storm events. The stormwater management system as proposed meets the Stormwater Management requirements of the DEP.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://soils.usda.gov/sqi/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.govnocatoriapp? agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contactl state _ officesf). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

(Not all prohibited bases apply to all programs.)

A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unrt is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties olthe soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unrt is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called 8 8.6% 9.7% 1.5% 0.3% 21 .3% 0.6% 41 .6% 7.2% 1.4% 4.7% 2.6% 100.0% Custom Soil Resource Report noncontrasting, or similar, components. They mayor may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erOSion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattem and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha- Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. 9 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I Custom Soil Resource Report Some surveys include miscellaneous areas.

thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality. Soil Qualities and Features Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil. Hydrologic Soil Group (Genesis HealthCare) Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long- duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (AID, BID, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. 22 Custom Soil Resource Report Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (AID, BID, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group 0 are assigned to dual classes. 23 I I I I I I I I I I I I I I I I I I I - - _ _Cu~oil_urc,-ort _ _ --- ---Map-Hydrologic Soil Group (Genesis HealthCare) 4r 4'58" 42' 4' 30" 1 :6,050 if prllted on A size (8.5" xiI") 5heet. 300 1,800 --- ---- MAP LEGEND Area of Interest (AOI) Area of Interest (AOI) Solis Soil Map Units Soli Ratings • A fiIiIliI AID .B fiIiIliI BID fiIiIliI C • ClD • D ----Custom Soil Resource Report Not rated or not available Political Features • Cities Water Features • Oceans ~~ Streams and Canals Transportation m ~ Rails ""'" Interstate Highways .-v-US Routes Z Major Roads B Local Roads - -- - -- MAP INFORMATION Map Scale: 1 :6,050 if printed on A size (8.5" x 11'1 sheet.

Currently, stormwater runoff from the existing site is treated for attenuation of peak flow rates but not for groundwater recharge. TSS removal is provided with parking lot sweeping and an existing constructed stormwater wetland. This plan includes provisions for treating runoff from the existing and proposed impervious areas. Peak runoff rates will be attenuated through an additional constructed stormwater wetland . Suspended solids will be removed through sediment forebays, a pocket wetland, and continued maintenance of the parking area. Groundwater recharge will be provided through 3 infiltration trenches. Redevelopment of this site will maintain the quality of the runoff from the existing site and treat all runoff from the proposed construction area. The proposed stormwater management system is in full compliance with the DEP's stormwater management requirements. 214 Worcester Street N.

Genesis' offices are located at 101 East State Street, Kennett Square, P A. This Operation & Maintenance Plan is transferable to future property owners. I Site Location: The site is located at the Heritage Woods facility, 61 Cooper Street, Agawam, MA. I Stormwater Management System: Genesis operates a nursing home on this site. The stormwater management system is designed to treat runoff for I the pollutants associated with this land use. To prevent soil from washing off the site during construction, the following Construction BMPs will be I implemented: I I • Hay Bales: A hay bale barrier will be placed along the downhill perimeter of the of the construction area before any clearing or grading takes place. • Construction Period Sediment Forebay: The proposed pocket wetland will be partially excavated and will serve as a sediment forebay during construction. I Permanent stormwater BMPs to be installed and maintained on this site include: I I • Infiltration Trench: Infiltration trenches are provided to recharge groundwater. • Sediment Forebay: Sediment forebays are provided to pretreat run-off prior to entering the infiltration trenches and constructed stormwater wetlands. • Constructed Stormwater Wetlands: A pocket wetland is provided to attenuate the peak run-offrates and remove suspended solids. I The locations of these devices are shown on the site development plans attached to this report. Proper maintenance of this stormwater management system is critical for the protection of the surface water I quality.
