Paradise Realty medical BuildingDrainage Repo October 3, 2002(revised January 8, 2003) (revised February 6, 2003) I. Introduction This report was originally prepared for a similar design, however, this revised report and calculations are for a reduced project. The new project consists of a smaller footprint for the building, (the original building was a single story 9,976 sf structure, the new building is a 5,625 sf two story structure), and a reduced area of pavement. This report is intended to present analysis and discussion for storm water management calculations and design performed for the Paradise Realty Groups proposed Medical Office Facility located at 766 North King Street in Northampton, Massachusetts. Construction improvements for the proposed project include: demolition of the existing building, construction of a new, 5,625 sq. foot structure intended to house medical and dental offices, reconfiguration and repaving of the existing parking lot, construction of a new parking lot, and installation of a new storm water management system and utilities. Impervious surface at the site will be increased from .42 acres to approximately .545 acres. The purpose of this analysis is to determine the 1, 2, 10 and 100 year peak flow rates for the site under current conditions and to design a storm water management system that maintains the existing peak flow rates while improving storm water runoff quality from the site. II. Site Soils According to the Natural Resources Conservation Service for the Central Part of Hampshire County (see attached soils map) the soils in the area of the proposed storm water management systems include HgA, Hinckley loamy sand, 0 to 3 percent slopes (hydrologic soil group A), Sc, Scitico silt loam (hydrologic soil group C) and Au, Amostown- Windsor silty substratum -Urban land complex (hydrologic soil group Q. Type A soils were utilized for the purpose of the storm water management analysis. III. Existing Conditions The existing site houses a former vehicle service station with associated flat paved areas. Directly behind the building, the site becomes a fairly steep upward slope covered by natural forest vegetation. This condition continues to the rear property line. The existing site is shaped like a bowl where storm water runoff leaving the site flows down the steep, vegetated slopes, collecting in the flatter, service station area. Grades at the site direct runoff towards two trench drains running the length Paradise Realty, dical BuildingDrainage Repo October 3, 2002(revised January 8, 2003) (revised February 6, 2003) of both site entrance driveways and a single leaching catch basin located in the rear of the paved area. Currently, both trench drains are full of sand and debris and are therefore, not functional. Similarly, the leaching catch basin does not appear to be working at this time. The original drainage concept apparently utilized the single leaching catch basin located in the rear of the lot for infiltration and these two trench drains which are believed to drain to a catch basin located on Route 5110 to remove runoff from the site. The municipal catch basin which drains the site also acts as a low point along the profile of Route 5110, collecting a portion of this roads runoff. The existing catch basin discharges all collected runoff through an 18" RCP pipe running under Route 5110 to an RCP flared end section located in the vegetated area of the off ramp from exit 21 off I -91. For storm water modeling purposes, the property lines at the site were used to bound the watershed with the control point located at the existing catch basin on Route 5110. IV. Proposed Conditions The proposed condition closely mimics the existing drainage patterns, utilizing the existing catch basin in Route 5110 as the ultimate point of discharge as well as the modeling control point. Incorporated in the proposed design are both storm water quality mechanisms as well as storm water retention and infiltration mechanisms with which to improve the quality of the runoff being discharged from the site as well as retain the peak flows off the site so as to equal the existing peak discharges from the site and to maintain groundwater recharge. Discussing the site from the rear, flow from the steep slope will be retained with a block wall equipped with a sub drain to relieve hydrostatic pressure behind the wall. This sub drain will be a 6" perforated pipe which discharges to the drainage trench located in front of the wall. The drainage trench collects both runoff from the wall sub drain as well as runoff generated by overland flow to the rear of the parking lot. All flow generated by the parking lot is put through a treatment catch basin which treats the runoff for total suspended solids and floatables utilizing stormceptor technology or an approved equal. Once treated, runoff from this catch basin is discharged into the detention chamber. In addition to the treated storm flows from the parking areas, runoff generated by the building roof is discharged directly into the detention structure. 2 Paradise Realty�dical BuildingDrainage Repo./ October 3, 2002(revised January 8, 2003) (revised February 6, 2003) The detention structure is approximately 20'x18' with two 12" inlets as discussed above and one 12" outlet located at the bottom of the tank. Flow from the tank is discharged to a control structure where three orifices, at varying elevations and in sizes ranging from 5 " -12" are used to control the discharge from the tank and maintain peak flows off the site at current levels. In addition to the control structure, a perforated pipe is proposed to be installed outside of the tank to allow flow within the tank to travel through the perforated pipe and into the surrounding gravel to ultimately provide for infiltration of some of the detained flow back into the surrounding groundwater system. Once flow is discharged from the control structure, it enters the municipal system through a new connection to the existing catch basin on Route 5110. V. Calculations & Design Under proposed conditions runoff will be collected, treated, peak flows detained, and piped to an existing catch basin which discharges flow to an existing vegetated area located within the off ramp of exit 21 off I -91. Based on the Rational Method, the proposed changes will not significantly effect the peak flow rates. Drainage calculations for the site were performed on Hydrocad version 6.0 using SCS TR -20 methodology. The downstream control point for this site under both existing and proposed conditions was the existing catch basin on Route 5110. Watershed subcatchment areas, runoff coefficients and watercourse slopes were based on the survey plans prepared by Harold Eaton Associates of Hadley, Massachusetts dated August 26, 2002. The proposed treatment chambers will be sized to treat the .4" storm runoff without bypass and all of this flow is detained within the detention structure. Calculations were performed for the 1, 2, 10 and 100 year frequency storms under existing and proposed conditions. Credit for infiltration provided by the perforated pipe attached to the tank was not taken. The results are shown in the summary table below. Paradise Realty � dical BuildingDrainage Repot � October 3, 2002(revised January 8 2003) (revised February 6, 2003) VI. Summary The storm water management system has been designed to nearly maintain or reduce and/or are equivalent to the existing peak flow rates under proposed conditions for the 1, 2, 10, and 100 year storm frequencies. Infiltration associated with the perforated pipe surrounding the detention tank, the perforated pipe at eh toe of slope at the rear of the developed portion of the site will provide infiltration from all "clean' storm water sources. Special care has been taken treat runoff with a series of best management practices to remove total suspended solids and improve water quality to the maximum extent practicable. These practices include street sweeping, catch basins equipped with gas and oil separators and deep sumps and an integral storm water treatment chamber within the system. The proposed system outlet mimics the existing condition and prior to construction erosion control barriers will be installed as shown on the site plans.

"Lighting Plan, Paradise Realty Group, Inc.' Sheet No. 1, prepared by Kim Lighting, dated October 1, 2002. In Granting the Special Permit and Site Plan Approval (major project), the Planning Board determined that. A. The requested use, to demolish an existing building and construct a 9,976 sq. ft medical office building with associated site development, protects adjoining premises against seriously detrimental uses because the proposed medical building is an allowed use within the Highway Business zone and the proposed medical building will serve to buffer the surrounding residential district. in addition, the applicant has included provisions for surface water drainage, sound and sight buffers and preservations of views, light and air as depicted in plans and information submitted with the application. B. The requested use will promote the convenience and safety of vehicular and pedestrian movement within the site and on adjacent streets, minimize traffic impacts on the streets and roads in the area because the proposed plan incorporates distinct changes in paving materials that visually highlight pedestrian movement thus separating the pedestrians from the vehicular traffic. A traffic impact statement was submitted indicating that the proposed use will have no change in the level of service and a majority of the patient visits would not be during peak traffic hours. Access for persons with disablides wilt be provided through the northern parking area and associated curb ramps, signage, line striping and walks have been provided, per ADA requirements. C. The requested use will promote a harmonious relationship of structures and open spaces to the natural landscape, existing buildings and other community assets in the area because the proposed structure will be an improvement to the area and the existing vegetative buffer will be retained along the boundary of the site. D. The requested use will not overload, and will mitigate adverse impacts on, the City's resources including the effect on the City's water supply and distribution system, sanitary and storm collection and treatment systems, fire protection, streets and schools because the - appiicant has shown on the plans an improved subsurface treatment system sanitary sewage will be treated onsite. E. The requested use meets any special regulations set forth in Sections 5.2, 6.5, 8.6, 10.1 & 11.0 of the Zoning Ordinance because the proposed project meets the requirements for a 20 percent reduction in parking and for a 10 foot reduction in the required width of the landscaped buffer strip. F. The requested use bears a postive relationship to the public convenience or welfare. The use will not unduly impair the integrity of character of the district or adjoining zones, nor be detrimental to the health, morals or general welfare because the proposed building will be harmonious with the surrounding business environment and will be an improvement to the existing abandoned gas station. The use shall be in harmony with the general purpose and intent of the Ordinance because the proposed project is an allowed use through a Special Permit as determined in Section 5.2 of the Northampton Zoning Ordinance. G.

How will the requested use protect adjoining premises against seriously detrimental uses? The proposed medical office building is an optimal use allowed by special permit from the planning board in the Highway Business zoning district. The proposed use will serve to buffer the surrounding residential district from an existing gas station and will make use of an abandoned used car lot. How will the project provide for: Surface water drainage: Storm flows generated on site will be collected by a series of 6" perforated pipe sub drains located along the various retaining walls, multiple catch basins located within both the proposed upper and lower parking lots as well as along the access road. Once collected, flow associated with paved areas will be treated by a treatment catch basin which treats the runoff for total suspended solids and floatables utilizing stormceptor technology or an approved equal. Once treated, runoff from this catch basin is discharged into a 20'x10' detention chamber along with "clean" runoff generated by a small grassed area and the building roof. The detention structure is approximately 20'x10' with two 12" inlets as discussed above and one 12" outlet located at the bottom of the tank. Flow from the tank is discharged to a control structure where three orifices, at varying elevations and in sizes ranging from 4 " -12" are used to control the discharge from the tank and maintain peak flows off the site at current levels. Once flow is discharged from the control structure, it enters the municipal system through a new connection to the existing catch basin on Route 5/10. The municipal catch basin which drains the site also acts as a low point along the profile of Route 5/10, collecting a portion of this roads runoff. The existing catch basin discharges all collected runoff through an 18" RCP pipe running under Route 5/10 to an RCP flared end section located in the vegetated area of the off ramp from exit 21 off I -91. Also see attached Drainage Report. Sound & Sight Buffers: Shade trees will be planted every 30' along street frontage in accordance with Northampton Zoning Ordinance Section 6.5 — Page 6 -13. The nature of the site is such that a limited amount of total area can be utilized in the construction of the medical center due to the steep topography. The applicant requests the planning board asses the site constraints and allow for a 10' reduction in the required landscape strip where it adjoins a lot in a residential district, as stated in Zoning Ordinance Section 6.5 — Page 6 -13. Paradise Realty Group� ---' October 3, 2002 The preservation of views, light, and air: The maximum height of the new structure is 20', consistent with zoning and the immediate surroundings. The rear of the structure will be built into the hillside. The site is enclosed on two sides by existing woodland, with a row of shade trees along North King Street offering filtered views to and from the site. An evergreen screen will be provided between the proposed use and the adjacent gas station. 8B. How will the requested use promote the convenience and safety of pedestrian movement within the site and on adjacent streets: L- The proposed circulation and parking scheme incorporates distinct changes in paving materials to visually highlight pedestrian movement, separating it from vehicular patterns. How will the project minimize traffic impacts on the streets and roads in the area? The proposed use will have no change in the level of service. See attached traffic report. In addition, the majority of patient visits will not be during peak hours. Where is the location of driveway openings in relation to traffic and adjacent streets? The proposed driveway opening is approximately 15' north of the existing driveway opening and will not alter traffic patterns on North King Street. What features have been incorporated into the design to allow for: Access by emergency vehicles: The proposed 24' driveway will provide access to the northern side of the structure. North King Street will provide access to the eastern side of the structure. The safe and convenient arrangement of parking and load spaces: The proposed structure will require 50 parking spaces. The nature of the site is such that a limited amount of total area can be utilized in the construction of the medical. — center due to the steep topography. The applicant requests the planning board assess the site constraints and allow for a reduction in the required number of spaces as per Zoning Ordinance Section 8.10 -6. Provisions for persons with disabilities: Accessible parking has been provided in the northern parking area adjacent to the proposed office building. Associated curb ramps, signage, line striping and walks have been provided per ADA requirements. Paradise Realty Grouoydc. October 3, 2002 8C. How will the proposed use promote a harmonious relationship of structures and open spaces to: The natural landscape: The proposed structure will be built into the hillside to limit disturbed area on site. An existing vegetative buffer will be retained along the boundary of the site to create a sense of enclosure. Existing buildings: The existing gas station and associated paving will be removed. Other community assets in the area: Contextual architecture will be an improvement to surrounding highway business uses, the closest of which is the neighboring gas station. 8D. What measures are being taken that show the use will not overload the City's resources, including: Water supply and distribution system: It is anticipated that the medical office building will use less than 1,000 gallons a day. All toilets will be low flush systems. Sanitary sewage and storm water collection and treatment systems: Sanitary sewage generated on site will be treated onsite through an improved subsurface treatment system incorporating a 2,000 gallon Septic Tank and concrete leaching chambers. The system will be designed in accordance with 310 CMR 15.00. Storm water collected on site will be detained as discussed above to ensure that discharges to the municipal system from the 1, 2, and 10 year storm events is equal to or less than the existing discharge flows from the site. Also see attached Drainage Report. Fire protection, streets and schools: �- The proposed 24' driveway will provide access to the northern side of the structure: North King Street will provide access to the eastern side of the structure. The proposed structure will minimally impact the city streets and will not have an `- impact on the municipal school system. How will the proposed project mitigate any adverse impacts on the City's resources, as listed above? No adverse impacts are anticipated. Paradise Realty Grou�c. —� October 3, 2002 8E. List the sections of the zoning ordinance that states what special regulations are required for the proposed project. How does the project meet the special requirements? 8.10 -6 Planning Board Site Plan Special Permit for a reduction of the parking requirements to eighty (80) percent of that required in the Table of Off - Street Parking Regulations where conditions unique to the use will reasonably justify such a reduction. The proposed structure will require 50 parking spaces. The nature of the site is such that a limited amount of total area can be utilized in the construction of the medical center due to the steep topography. The applicant requests the planning board assess the site constraints and allow for a reduction in the required number of spaces as per Zoning Ordinance Section 8.10 -6. 6.5 - 113 Planning Board Site Plan Approval allowing for a ten (10) foot reduction in the required width of the landscaped buffer strip, provided that the Board finds that a sight impervious wall or fence is erected of appropriate materials and sufficient height to screen abutting properties and will provide at least as much noise mitigation as the vegetated barrier described above. L The nature of the site is such that a limited amount of total area can be utilized in the construction of the medical center due to the steep topography. The building will be constructed into the hillside thus reducing the impact of the new structure on the surrounding area. Due to the fact that there are no residences in the immediate area, the 10' reduction will have a minimal impact on the adjacent parcels. The building will serve as a sound buffer from the parking area, and additional evergreen trees will add to the existing vegetative screen. The applicant requests the planning board asses the site constraints and allow for a 10' reduction in the required landscape strip where it adjoins a lot in a residential district, as stated in Zoning Ordinance Section 6.5 — Page 6 -13. ` 8F.

J October 3, 2002 TRAFFIC IMPACT STATEMENT I. Introduction This report presents an abbreviated traffic study to analyze the impact of the proposed Paash Medical Office Facility to be located at 766 North King Street in Northampton, Massachusetts. The proposed office facility will consist of a new building with a foot -print of 9,986 square feet, an upper and lower parking area, access road to the upper lot, and a stormwater management system. The purpose of this analysis is to determine the traffic expected to be generated by the proposed office facility during peak hours and to evaluate it with regard to capacity and safety of the adjacent roadway. The study's findings and recommendations are briefly summarized below. Based on the Institute of Transportation Engineers (ITE) Trip Generation manual, _ 6` Edition, the on site AM peak and on site PM peak traffic flows do not affect the current level of service on the adjacent roadway, Route 5110. II. Data Survey The existing site was previously utilized as a gas station, service station, and later �. a used car /service station area. The average vehicle trip tables in the Institute of Transportation Engineers (ITE) Trip Generation manual, 6` Edition shows data based on only six studies. It is our belief that this information would provide erroneous traffic volumes for the existing condition. Therefore, the proposed site use was . utilized to determine peak am and pm traffic volumes which was then used to determine the existing and proposed level of service at the adjacent roadway, Route 5110. According to the Institute of Transportation Engineers (ITE) Trip Generation manual, 6` Edition, the on site AM peak hour of adjacent strret traffic, one hour between 7 and 9 am. Per 1000 sq. feet of gross floor area is 24.3 vehicles per hour. The on site PM peak hour of adjacent street traffic, one hour between 4 and 5 pm. per 1000 sq. feet of gross floor area is 36.6 vehicles per hour. Utilizing this data in conjunction with data provided on ADT's along this portion _ of Route 5110 by the. Massachusetts Highway Department, the existing level of service at this location was determined to be LOS D. The proposed condition, - including the traffic impacts from the new site do not alter this LOS. Therefore, the proposed development does not impact traffic along Route 5110 at this location. III. Project Design Parameter Current Conditions 766 North King Stre et Paash Medical October 2, 2002 Abrivated Traffic Study AM (9:00) Peak Volume: 1,119 cars 416 WB 703 EB PM (5:00) Peak Volume: 1,603 cars 687 WB 916 EB Roadway Classification: Urban Arterial Roadway Width Assume: ±36' Projected Conditions As discussed above, the Institute of Transportation Engineers (ITE) Trip Generation manual, 6` Edition, was utilized to determine the peak am and pm vehicle trips. The expected traffic volumes generated by the project were calculated by application of the ITE trip rate for a Medical - Dental Office Building, land use code 720. ITE reports that the average rate of trips generated by a Medical - Dental Office Building is 2.43 Trips for AM and 3.36 Trips for PM per sq. feet of gross floor area. The site traffic estimates shown below assume that the office building will operate at full capacity. Medical Dental Office Building: A.M.

October 3, 2002 DRAINAGE REPORT Paradise Realty Mebical Building October 3, 2002 Drainage Report I. Introduction This report is intended to present analysis and discussion for storm water _ management calculations and design performed for the Paradise Realty Groups proposed Medical Office Facility located at 766 North King Street in Northampton, Massachusetts. Construction improvements for the proposed project include: demolition of the existing building, construction of a new, 9,976 sq. foot structure intended to house medical and dental offices, reconfiguration and repaving of the existing parking lot, construction of a new, upper level parking lot on the terrace above the building, addition of a new access road to the upper parking area, and installation of a new storm water management system and utilities. Impervious surface at the site will be increased from .42 acres to approximately .7 acres. The purpose of this analysis is to determine the 1, 2, 10 and 100 year peak flow rates for the site under current conditions and to design a storm water management system that maintains the existing peak flow rates while improving storm water runoff quality from the site. II. Site Soils According to the Natural Resources Conservation Service for the Central Part of Hampshire County (see attached soils map) the soils in the area of the proposed storm water management systems include HgA, Hinckley loamy sand, 0 to 3 percent slopes (hydrologic soil group A), Sc, Scitico silt loam (hydrologic soil group C) and Au, Amostown- Windsor silty substratum -Urban land complex (hydrologic soil group Q. Type A soils were utilized for the purpose of the storm water management analysis. III. Existing Conditions The existing site houses a former vehicle service station with associated flat paved areas. Directly behind the building, the site becomes a fairly steep upward slope covered by natural forest vegetation. This condition continues to the rear property line. The existing site is shaped like a bowl where storm water runoff leaving the site flows down the steep, vegetated slopes, collecting in the flatter, service station. area. Grades at the site direct runoff towards two trench drains running the length of both site entrance driveways and a single leaching catch basin located in the rear of the paved area. Currently, both trench drains are. full of sand and debris and are therefore, not functional. Similarly, the leaching catch basin does not Paradise Realty Meal Building October 3, 2002 Drainage Report appear to be working at this time. The original drainage concept apparently utilized the single leaching catch basin located in the rear of the lot for infiltration and these two trench drains which are believed to drain to a catch basin located on Route 5110 to remove runoff from the site. The municipal catch basin which drains the site also acts as a low point along the profile of Route 5110, collecting a portion of this roads runoff. The existing catch basin discharges all collected runoff through an 18" RCP pipe running under Route 5110 to an RCP flared end section located in the vegetated area of the off ramp from exit 21 off I -91. For storm water modeling purposes, the property lines at the site were used to bound the watershed with the control point located at the existing catch basin on Route 5110. IV. Proposed Conditions The proposed condition closely mimics the existing drainage patterns, utilizing the existing catch basin in Route 5110 as the ultimate point of discharge as well as the modeling control point. Incorporated in the proposed design are both storm water quality mechanisms as well as storm water retention and infiltration mechanisms with which to improve the quality of the runoff being discharged from the site as well as retain the peak flows off the site so as to equal the existing peak discharges from the site and to maintain groundwater recharge. Discussing the site from the rear, steep area towards Route 5110 and the discharge catch basin, flow from the steep slope will be retained with a block wall equipped with a sub drain to relieve hydrostatic pressure behind the wall. This sub drain will be a 6" perforated pipe which discharges to the catch basin located in the upper parking lot. This catch basin collects both runoff from the wall sub drain as well as runoff generated by the upper parking area and moves it to the lower portion of the site through a series of manholes and piping. Runoff from the upper parking lot is then combined with runoff from the access road which is collected by two other catch basins, located on either side of the roadway at its entrance to Route 5110. In addition to this flow volume, flow generated by the lower parking lot is added and all of this is put through a treatment catch basin which treats the runoff for total suspended solids and floatables utilizing stormceptor technology or an approved equal. Once treated, runoff from this catch basin is discharged into the detention chamber. In addition to the treated storm flows from the parking areas, runoff generated by the building roof as well as additional runoff collected by two other 6" wall sub - drains located up -slope of the building and a local field catch basin is discharged directly into the detention structure. Paradise Realty Mee�cal Building October 3, 2002 Drainage Report The detention structure is approximately 20'x30' with two 12" inlets as discussed above and one 12" outlet located at the bottom of the tank. Flow from the tank is discharged to a control structure where three orifices, at varying elevations and in sizes ranging from 4 " -12" are used to control the discharge from the tank and maintain peak flows off the site at current levels. In addition to the control structure, a perforated pipe is proposed to be installed outside of the tank to allow flow within the tank to travel through the perforated pipe and into the surrounding gravel to ultimately provide for infiltration of some of the detained flow back into the surrounding groundwater system. Once flow is discharged from the control structure, it enters the municipal system through a new connection to the existing catch basin on Route 5110. V. Calculations & Design Under proposed conditions runoff will be collected, treated, peak flows detained, and piped to an existing catch basin which discharges flow to an existing vegetated area located within the off ramp of exit 21 off I -91. Based on the Rational Method, the proposed changes will not significantly effect the peak flow rates. Drainage calculations for the site were performed on Hydrocad version 6.0 using SCS TR -20 methodology. The downstream control point for this site under both existing and proposed conditions was the existing catch basin on Route 5110. Watershed subcatchment areas, runoff coefficients and watercourse slopes were based on the survey plans prepared by Harold Eaton Associates of Hadley, Massachusetts dated August 26, 2002. The proposed treatment chambers will be sized to treat the .4" storm runoff without bypass and all of this flow is detained within the detention structure. Calculations were performed for the 1, 2, 10 and 100 year frequency storms under existing and proposed conditions. Credit for infiltration provided by the perforated pipe attached to the tank was not taken.. The results are shown in the summary table below. I— Paradise Realty Meb&al Building `J October 3, 2002 Drainage Report VI. Summary The storm water management system has been designed to nearly maintain or reduce and/or are equivalent to the existing peak flow rates under proposed conditions for the 1, 2, 10, and 100 year storm frequencies. Special care has been taken treat runoff with a series of best management practices to remove total suspended solids and improve water quality to the maximum extent practicable. These practices include street sweeping, catch basins equipped with gas and oil separators and deep sumps and an integral storm water treatment chamber within the system. The proposed system outlet mimics the existing condition and prior to construction erosion control barriers will be installed as shown on the site plans. 4 S r * 'a.- • r w S g� � df: } a � yray a r i � '� ,f y t v{ H jJQAV- ilk J q P e Sy r• ,} iJ� v ` , r . �, �.: Y s ' iR� '« ,y 4 ' ,+I'd ..,fir ^+� � � `� �.: ' . � • Y moo:• °. -� :��.- � 1 ' �� , �� • e�° :•k �^� * ems ' iSl� t y �, � `�% l i k�� t om} � t'�e� • � � k` I t k .�• 1 t ,� , � ,� a � �/1� ��. ff { IR' 0 bb cd a N O a5 3 3 3 J N Figure 2 -7a - Precinitation `values for ":assachusetts 2. : 9 e FRANIIUN 3.0" ESSEX 3.2" MIDO i= SUfFOt ti NA ORCESTER W O 1 M N O� 1 I& O , 9 S O RAINFALL DATA MAP 2 -YEAR, 24 HOUR PRECIPITATION (INCHES) � TP -40 3. 3.6'1 NANTUCKET 3.8" — ESSEY FRANQA Z ' MIOOIESE! f WORCESTER 0� NAM�lRRE W O M� • NA 'CA 4.4 .. s� g o s A 0 RAIWALL DATA MAP 4. 5- YEAR,24 -HOUR PRECIPITATION (INCHES) .0-d.� I � d NANTUCKET TP -40 (210 -EFM, Am-.end.
