Meeting Notes LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 1. Executive Summary The assignment given to Donham & Sweeney - Architects was to provide the Permanent Building Committee with a space needs analysis and conceptual design related to the renovation/ expansion of the Police Station. Beginning in January 2010 we interviewed Department personnel to determine the space needs for each division within the Department, we prepared an engineering analysis of the building, and we undertook a preliminary zoning review and analysis of the site. Preliminary schematic design options were developed to meet the identified space needs. These options were reviewed with the Permanent Building Committee and the Police Department, and over a series of meetings were refined leaving one option, which calls for an addition to and renovations of the present building. Preliminary construction cost and project cost estimates were also prepared. We concluded that, due to modernization and updates to the Massachusetts Building and Life Safety Codes and the enactment of accessibility legislation since the facility was originally constructed, a major work project undertaken on the building would expose serious Building Code, Life Safety Code and Accessibility Code deficiencies. Its heating, ventilating, air - conditioning, and electrical systems are past their expected useful life, are inefficient and we believe should be replaced. The Police Station, in addition, is greatly undersized for its present occupancies and uses. For instance, some of the department equipment is stored in shipping containers, a trailer and an SUV. Currently, the Police Department has 13,060 SF of space in the 1956 building but needs a total of 289308 SF, including a qualifying firing range. The range presently in the building, which is too small, cannot be physically expanded. A new expanded range at that site would necessarily be above ground and the Permanent Building Committee had serious reservations about doing that in a residential neighborhood. If an off -site firing range were to be provided the total gross area would increase because of the needed support facilities. The 1956 building was designed to support a town community that was about 70% of the size of the current population and generated half as many calls in a year as it now does. The major shortcoming of the building is lack of space. The significant space shortage confirmed in this study should be addressed. We recommend renovating the existing building and constructing and addition to the rear and right side. The location of the Police Station is ideal. The cost estimate comparisons, including hard construction costs, so- called `soft' costs, and contingency show: Police Station, Renovation and Addition $12M to $13M If as recommended, it is decided to design an addition and renovation to the present building, we project that the A/E fees to complete Design Development, Construction Documents, and Bidding would be in the range of $750,000 to $850,000. These tasks could be completed within the course of a year thus obtaining bids for a subsequent funding request for construction which would be made at a later Town Meeting. The funding request for construction would include fees for construction administration, designing furnishings, and some of the LEED certification fees. If the town decides to postpone the project, addressing issues with the building fabric and systems can probably be postponed 5 -7 years. However, regular maintenance and normal replacement of failed mechanical and electrical systems should continue. 2 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 2. Space Needs Summary The present Police Station was built in 1956 and has 13,060 SF of space. An additional 400 SF exists in the form of two shipping containers housing recovered bicycles and equipment for the Department's outdoor firing range and use of force programs. Other significant changes since 1956 affect the space needs of the Department.

OF RESPONSES F.T. STAFF SPACE NEEDS The building has been renovated several times over the last 50 years in an effort to squeeze more useful space out of the existing floor plans. In some cases, this has resulted in creating dysfunctional and potentially dangerous conditions. One instance is that a prisoner being brought into the detention area has to enter via the maintenance garage with its abundance of potential weapons, through the middle of the male officer's locker rooms, across an egress hall to the detention area. The removal of a stairwell in 1970 has a number of unintended consequences as described in the Police Chief's report in Appendix B. Other renovations had the effect of reducing program space. For instance, storage space was lost to new mechanical equipment. Two Janitor's closets were similarly taken for other uses. See Appendices B & C for detailed histories of space needs and staffing. Functions that have been added since 1956 include; • Combined E -911, Dispatch and EOC, with a minimum of 2 FT dispatchers per shift • Juvenile Cell • Women's Lockers • Cadet Program • Parking Enforcement • Animal Control • Crossing Guards • Special Police Officers • Physical Fitness • Emergency Generator • Specialized Vehicular Equipment The mission, staff and equipment have grown in the last 54 years but the spaces to house and maintain them have not. In 1993, Lexington commissioned the "Lexington Public Buildings Facility Study ". It stated that the Police Station "needs modernization and expansion." In 2000, the "Space /Building Needs Advisory Committee Report" identified a number of shortcomings with the existing building, both in space deficiencies and physical conditions and went on to recommend renovating and adding onto the present building. Donham & Sweeney - Architects was retained in January 2010 to prepare a space needs analysis followed by options for schematic design solutions to meet the Department's needs. Our first step was to interview about a dozen staff members, looking carefully at how the Department functions and particularly at their furnishings and equipment needs. In addition to our experience with approximately 30 other police stations, we took into consideration the recommendations of the International Association of Chief's of Police [IACP] and the Public Health and Plumbing Codes of the Commonwealth of Massachusetts. Our space needs study indicated that 28, 380 SF was needed looking ahead 20 to 25 years. This is comparable to other similar towns.

Building Analysis Summary Together with our engineers we reviewed the present building to gauge its programmatic, technical and functional use. We found that the present building is woefully inadequate for the tasks being carried out by the Department and that the facility has a number of technical and functional areas of concern. However, generally, the fabric of the building is in good condition for a 54 year old building. The present building is too small for present staff, equipment & services. This is most clearly seen in compromises to critical operations and equipment: some equipment must be parked outdoors in two shipping containers, a trailer and an SUV. The physical constraints of the building pose challenges to the day to day operation of the Department: there is no training space within the building; the locker room is half the size needed for today's equipment, clothing and operation manuals storage; there is no secure sallyport; prisoner entry to the building is unsecure and dangerous; there is a critical lack of storage space such that sensitive records are not able to be stored securely; there is no elevator for moving heavy equipment, files and persons with disabilities; and the sub - basement firing range is inadequate in all regards including the required qualification testing. The building contains many issues which, under the present Massachusetts Building Code, would be considered deficiencies. Most prominently, there is no sprinkler system, little universal access, insufficient ventilation and grossly inefficient heating and air - conditioning systems. See Appendix E. Structurally, the building does not conform to today's Building Code requirements for seismic resistance. The Code does not yet require this to be addressed, but it is a good public policy question whether the center of emergency communication and response in the Town of Lexington should be vulnerable to earthquake damage. Any significant alteration to the existing structure will require upgrading the entire structure at great expense. See Appendix D. If it is decided to postpone proceeding with the recommended plan to renovate and add on to the building, other deficiencies identified in the structural and mechanical equipment reports should be remedied as funds permit. The existing site is ideally located for visibility and response times and a police station use there should be continued. Detailed structural, mechanical, electrical, and plumbing systems are near the end of their useful life. A detailed analysis of these systems can be found in Appendix E 0 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 4.

Regulatory Review Summary OVERVIEW The Police Station Project will receive design review by the Permanent Building Committee and by the Police Department, as it has throughout the schematic design phase. However, in addition 3 other public bodies will have a design review role; the Board of Zoning Appeals, the Historic Districts Commission, and the Lexington Design Advisory Committee. We recommend that some strategy be developed to coordinate design review among these different bodies. ZONING Reuse of the existing Police Station lot for an expanded Police Station is a permitted use under Lexington's Zoning By -Law. However, a Special Permit with Site Plan Review is required from the Board of Appeals. A traffic study is needed for this Review. In addition, a series of Variances from the Zoning By -Law are needed, including; FAR; 0.25 is the maximum permitted, the total FAR for all buildings on this site has not been determined, but likely exceeds 0.25. Site Coverage; 15% is the maximum allowed by Special Permit, the plans show a 18% coverage Parking; 5' building setback required, 2' provided; 5' lot -line setback required, 0' provided A preliminary Zoning Analysis can be found in Appendix H. Because the Police Station is on a large lot with 4 separate buildings and multiple uses, the applicability of the Town's dimensional controls and parking requirements is open to interpretation by the appropriate Town Boards. HISTORIC DISTRICTS COMMISSION The Police Station site is within the Munroe Tavern Historic District. The Commission consists of 5 members and they have issues a set of design guidelines that apply to all the Districts. The town will need to apply for a Certificate of Appropriateness and one or more public hearings will be required. The Commission encourages early informal meetings with them as the design is being developed. 17 DESIGN ADVISORY COMMITTEE This Committee consists of 9 members and 8 associates, all of whom are required to be design professionals. The Committee's charge is "to assist the Town in providing professional design guidance for Town buildings." Their recommendations are made to the Board of Selectmen. UM LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 6. Preliminary Cost Estimate Summary We estimate the total project costs for the renovation of and addition to the existing building, inclusive of fees, furnishings and other "soft' costs, to range between $12M and $13M with fees and expenses required to bring construction bids to a Spring 2013 Town Meeting ranging from $750,000 to $850,000. The funding request for construction would include fees for construction administration, designing furnishings, and some of the LEED certification fees. Project cost summary follows. Detailed preliminary construction cost estimates can be found in Appendix G. The detailed construction cost estimates were performed prior to gaining an understanding of the time frame for any future construction work and therefore only show escalation into spring 2011. Subsequently we have been directed to assume construction work would begin in Spring 2013. The cost summaries reflect that change. 19 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT Preliminary Cost Estimate - Police Station (Addition / Renovation) SOFT COSTS Design & Engineering 3 Architectural and Engineering fees @ 8.7% $737,000 $553,000 4 Allowance for extra services, change orders @ 5% $37,000 5 Permitting $20,000 $20,000 6 Reimbursable expenses $15,000 $11,000 7 Geotech Consultant (including borings) $20,000 $20,000 8 Furnishing Design fee (10% of furnishings) $28,000 9 Tel/Data & Security Consultant $30,000 $24,000 10 Communications Consultant $30,000 $24,000 Total Design & Engineering $917,000 Professional Services 11 Owners Project Manager& Clerk ofthe Works $150,000 12 LEED Certification $50,000 $40,000 13 Commissioning $50,000 $20,000 14 Construction Testing $20,000 $30,000 15 LSP $30,000 Total Professional Services $300,000 Fixtures, Furnishings & Equipment 16 Furnishings @ $6 /sf $280,000 17 Allowance for Computer Equip. & Network $100,000 18 Allowance for Communications Equipment $150,000 19 Allowance for Movable Equipment $50,000 20 Allowance for Telephone System & Equip. $50,000 21 Allowance for Security & CCTV System $80,000 Total Fixtures, Furnishings & Equipment $710,000 Temporary Relocation Costs 22 Temporary Facilities, allowance $300,000 23 Utility Connections, allowance $100,000 24 Rehabilitation of Temporary Space $50,000 Temporary Relocation Costs $450,000 Project Related Expenses 25 Topographic and Utility Survey $15,000 $15,000 26 Hazardous Materials Survey $30,000 $20,000 27 Haz -Mat Clean-up $50,000 28 Structural Peer Review $10,000 $10,000 29 Printing bid sets & advertising $20,000 $20,000 30 Moving Expenses (2 moves) $25,000 31 Utility Fees & Backcharges $30,000 32 Legal Costs $20,000 33 Bonding $0 34 Building Committee Costs $0 35 Builder's Risk Insurance $60,000 Total Project Related Expenses $260,000 $807,000 Total Soft Costs $2,637,000 Total Project Costs $10,831,000 Project Contingency @ 12% $1,300,000 PROJECT TOTAL $12,131,000 21 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 7. Schedule We recommend that the Town proceed with Design Development, Construction Documents and Bidding of this project so that it can be brought to the Spring Town Meeting in 2013. This long schedule allows for the extensive public review process required for this project on this particular site. The chart below describes the recommended steps and timing. 23 Fall 2010 Spring 2011 Fa112011 S rin 2012 Fall 2012 Spring 2013 Fall 2013 Presentation to BOS 10/4/2010- 11/9/2010 Spring Town Meeting 03/21/2011 - 5/21/2011 - Design Development 07/01/2011- 11/01/2011 Permitting 11/01/2011- 05/11/2010 Construction Documents 05/01/2012- 11/01/2012 Bidding 01/02/2013-03/01/2013 Spring Town Meeting 03/20/2013- 04/24/2013 Construction Contract Award 05/01/2013- 06/01/2013 Construction 06/01/2013-09-01/2014 23 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 8. Building Deficiencies and Recommended Work The principal building deficiencies are lack of space and a dysfunctional layout. The effects of this on the operations of the department are described in the two Police Chief's Reports, found in Appendices B and C. Other deficiencies are described in the Mechanical and Electrical Engineering Report, Appendix E. They are the expected maintenance and end -of- useful -life items one would expect in a 54 year old building that is used 24 hours a day, and 7 days a week. None of these systems is expected to fail completely in the next 5 to 7 years. 25 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 9. Police Station Location In the course discussion has occurred on the topic of abandoning the present building and constructing a new one elsewhere, thereby avoiding the costs of temporary relocation. However, studies have shown that the present building is nearly ideally located from several perspectives. The site location criteria recommended by the International Association of Chiefs of Police (IACP) include centrality of location, high visibility, prominence, and good response time, all met by the present site. The ability to mount Lexington's foot patrol through the central business district without the use of patrol cars is another feature of the present site. Renovating an existing building is a more environmentally sustainable strategy than demolishing and building new. Reusing and expanding the present building maintains the distinguished architectural composition and historical integrity of the Town Hall complex. 27 LEXINGTON POLICE STATION SCHEMATIC DESIGN STUDY REPORT 10.

Police Chief s Report, "Space Needs — A Review of Past Programs and Staffing" `pays MOR. o° 1775 �c U k A Town of Lexington as o` ; Police Department 15 75 Massachusetts Avenue, Lexington, MA 02420 APRIL Yr �FXfNC 0� Space Needs — A Review of Past Pro rams and Staffing October 31, 2010 By Chief Mark J. Corr The Report of the Board of Selectmen, as written in the Town Report in 1955 highlighted "New Town Office Building." "In 1928 when the present Town Office Building was completed it was thought that in tern years additional space would be needed, particularly in regard to housing the Police Department. Since that time the departments of the town have multiplied and those then in existence have increased in size. The population in 1928 was about 7,000 and is now nearing the 25, 000 mark. The Board of Selectmen is strongly recommending that the plans to be submitted to the Town Meeting be approved. The plans will show a building with exterior exactly the reverse of the present building to be located on the opposite side of Cary Memorial Hall l. The funding was approved and in the 1956 Town Report, the Selectmen wrote: "The year 1956 was a rather heavy building year with 521 building permits issued. Some of the major buildings being erected are the new Church of Our Redeemer, the new Methodist Church, the new St. Brigid's Church, the Josiah Willard Hayden Recreation Center, the new Additional Town Office Building, the addition to the Franklin School, tine addition to the High School and the Manhattan Building." Police Town Reports — Staffing Identified POLICE; During the tenure of Chief Rycroft (1943 to 1965), the Police Department's annual report cited accident and crime data only. Later in the 1960's Chief J. Corr included police officer staffing levels as part of the report. Conveniently, the first year used was 1955 (the year before the Police Station was built). The following figures show the actual officers available and not the authorized strength. For example, in 1970 the Department was authorized for 54 officers. 1955 29 1964 32 1973 49 1956 29 1965 35 1974 46 1957 30 1966 36 1975 51 1958 31 1967 43 1976 51 1959 33 1968 42 1977 54 1960 34 1969 47 1961 31 1970 47 1962 32 1971 50 1963 33 1972 49 Page 1 of 9 In 1977, the Police Department hired 8 full -time officers to reach the authorized strength. In that year, the Police Department was funded for 61 full -time employees and 25 part-time employees. The full -time staff was: 54 Officers (patrol to Chief) 2 Dispatchers 4 Administrative Staff 1 Mechanic 25 Part-time employees included 6 Cadets and 19 crossing guards. Our current records allow us to track the changes since 1977. 1990 53 officers as one position is cut to fund a full -time Parking Enforcement Officer. 2003 41 officers after funding for 12 positions lost with a failed override 2004 48 officers due to an override refunding 2009 47 officer with funding lost for a School Resource Officer at MMTech DISPATCH: The Police Department was traditionally staffed with 2 full -time dispatchers who assisted full -time desk officers to provide police dispatching services. In 1994, the first combined police, fire and 9 -1 -1 dispatching center was established and dispatchers for the police and fire were consolidated under the Police Department budget. The budget permitted 24 -hour staffing coverage (8- dispatchers) for a 2 -2 -1 program (two dispatchers for days and evenings, one overnight). In 2003, the dispatch staff was temporarily cut to 7 full -time dispatchers and restored to full staffing in 2004. In 2005, a 9th dispatcher was hired to provide a 2 -2 -2 program. With a program designed to provide two dispatchers on -duty at all time, the program has the minimum number of employees possible. All leave or absences generates overtime. CIVILIAN STAFF: The volume of paperwork and `behind the scenes' activity has been traditionally managed by four (4) administrative personnel. From approximately 1970, an Office Manager and a Records Clerk were responsible for police reports, court records and general management (payroll, accounts payable /receivable, Chief's correspondence) and two Clerks to manage the high volume of traffic data (parking tickets, accidents, citations). From 1998 to 2004, this staffing was pared down to two full-time staff members with the understanding that Police Cadets (3 to 5 part -time students) would assist. In 2003, the Cadet program was temporarily eliminated. It was impossible to manage the Police Department without this staff. As of 2010, there are three full-time and one part -time staff members. CADETS. The Cadet program (started in 1968) has been a big success with students from Iocal colleges and universities spending their co -op and break periods working full -time as Cadets. In the early 90's, this program transitioned into a part -time program with five Cadets. In 2003, the override failure temporarily ended the program, but was later funded for three Cadets (no benefits) working less than 19 hours per week. In 2009, one of these Cadet positions was exchanged for a part -time Clerk. Page 2 of 9 Cadets are used for many services. They assist the public at the station, provide dispatching backup, direct traffic at congested intersections, enforce parking regulations, run errands, wash and clean vehicles, as well as tending to along list of data entry projects. Given the $9, $10 or $11 per hour pay, the Cadet program continues to provide excellent dividends. MECHANIC. The Police Department has maintained its fleet with a full -time mechanic for 50+ years. Prior to the construction of the new Public Services building at 201 Bedford Street, the design firm studied the possibility of consolidating police mechanical services with DPW operations. The study concluded that the most efficient and effective use of the Mechanic was for the position to remain at the police station. The Mechanic is a "Jack of all trades" who is able to help maintain parking meters; the wide assortment of police vehicles and equipment; is a fully trained police officer ( works PT in Carlisle, MA) and is fully trained to perform police, fire, 9 -1 -1 dispatching. PARKING ENFORCEMENT OFFICER. In 1990, the first Parking Enforcement Officer was hired to cover Lexington Center full -time engaging in parking enforcement, meter repair, and coin collection. This consolidated work previously performed by a second full -time officer assigned to Lexington Center. ANIMAL CONTROL OFFICER. In 2007, the part-time Animal Control Officer was moved from Inspectional Services to the Police Department. This has streamlined how many complaints (most received at the police station) are managed by the ACO. It has also improved direct supervision of the ACO. CROSSING GUARDS. The crossing guard program predates the police station and the women hired for the program were considered Police Women without the power to make arrests. The number of crossing guards has grown and contracted with the number of schools. In the early 1990s, the crossing guard program was shifted to the School Department with supervision shared with the Police Department. In 2009, the entire program was returned to the Police Department. There are presently 14 school crossings and the program provides two additional crossing guards to cover absences. SPECIALS. When the Civil Defense Act was implemented and used at its peak in the 1950's into the 1960's (given the perceived threat from the Soviet Union and later the Civil Rights demonstrations), the Town at the recommendation of the Police Chief appointed "Special" police officers. These reputable local citizens and retired police officers were authorized to assist the Police Department. Although retired Lexington Police Officers continue to be appointed as Special police officers (10 active as of 2010), the program has been significantly pared down with support personnel being appointed as Traffic Officers. Many of the Traffic Officers work for Lexington in some other capacity such as Cadets, Dispatchers, Crossing Guards and Firefighters. Page 3 of 9 Police Department Programs In assessing space needs for the Police Department, the demand for space is only partially driven by the number of personnel. Program and equipment expansion significantly impact the need for more square footage. The 1955 Town Report made it clear that accommodating the expanding Police Department helped drive the need for a new building. Even then, only the basement and first floor of the station was dedicated to Police operations, while the second floor was used for the Health Department and Inspectional Services. Fifteen years later, the continuing growth of police services required that the building be renovated again and fully committed to the Police Department needs. Forty -years later, the police station is inadequate to house police programs. DISPATCH. In the original police station, a 6' x 10' room was suitable for a sole dispatcher, answering phones and broadcasting police calls via radio. This room expanded to roughly 10' x 10' in the 1970 renovation and was fully supported by a police officer at the front desk. In 1994, with the arrival of enhanced 9 -1 -1, Lexington combined the police, fire and 9 -1 -1 dispatching services at the police station. The Honorable Ralph Gants (now serving as a Justice of the Massachusetts Supreme Judicial Court) independently reached conclusions about Lexington's dispatching operations when investigating the unfortunate murder of Kathleen Dempsey. Justice Gants validated the Town's decision to combine dispatch operations at the Police Department. The Dispatch design in 1994 was far from ideal and this had more to do with the lack of available space in the police station as well as public pressure to keep the cost down. The Public Safety Staffing Review Committee in 2004 wrote: The physical facility which the Combined Dispatch must work is nothing short of appalling. The room is long and narrow. It is uncomfortably hot in the summer and too cold in the winter. The layout is drab, the chairs and tables antiquated and uncomfortable, This situation should be remedied as soon as possible. By 2007, the Police Department needed to replace a radio network that had nearly doubled its life expectancy. All new radios required the redesign and enlarging of the dispatch center to accommodate all new equipment. Approximately two- thirds of the $840,000 project was dedicated to equipment and other soft: costs. The Communication center was designed for our 2010 -2020 needs, but was not designed to accommodate long term growth. The program resulted in the loss of a small administrative office to make room for new computer equipment and the new 9 -1 -1 system. The Communication Center is an emergency operating center (EOC) for day -to -day emergencies. Additional large screen video displays will be necessary in the future for observing off site locations when security cameras are eventually mounted. GPS for police and other emergency equipment will be used at some point in the future and will require a large lighted map. The center does not have adequate display boards (such as white boards) for tracking local emergencies. Dispatch is one program that must have sufficient space to expand in the future. Page 4 of 9 DESK and COMMUNITY SPACE. The police station presently has no accommodations for the public. Whereas the Police Department is open 24 -7, heated and cooled through out the year, it is an excellent location for a community space. A community room could serve as a training room, emergency staging point, heated shelter during localized winter emergencies and as a cooling station during summer heat waves. Public meetings could also be held, any time, without opening other public buildings. The Public Lobby is an excellent location for public information displays. The public comes to the police station to manage traffic and parking tickets matters, report crimes, seek other advice, and at times to wait for someone to be bailed out. It is common for one or more individuals to be in the lobby, and this is problematic when someone is emotionally charged. Unfortunately, the Police Department has had armed assaults in the lobby. In one instance, a young man carne into the police station with a gun with the intent to shoot the desk officer. The disturbed man expected other officers to shoot and kill him (suicide by cop). These types of physical threats to police operations require the "public" area to be segregated and secure from the interior of the police station. COMMANDING OFFICER The Police Department has been very successful with a ranking officer in charge of the police station at all times. The Gants report highlighted the advantages of having a police supervisor monitoring dispatch operations 24 -7. Typically, a police Lieutenant or Sergeant uses the Commanding Officer's (C.O.) room to manage the police operations. He /She also listens to all police, fire and 9 -1 -1 operations to insure community needs are met. The C.O. insures that the building is secure and supervises the cell block. In the 1950's, the C.O. sat in a chair behind the desk officer. Since 1970, there is a proven advantage to giving the C.O. space immediately accessible to dispatch, desk operations, and the public. ANIMAL CONTROL & PARKING ENFORCEMENT With the addition of the Animal Control Officer to the police operations, a desk and phone was set up in an open meeting room. Later in 2007, a small storage and ID room was redesigned to provide a small office. The animal shelter on Westview Avenue however is seriously damaged by water and the property is presently used by the DPW. The Animal Control function would benefit by having direct public access, a small shelter for animals and refrigeration for carcasses that may need to be tested for viruses. With the expansion of the Parking Enforcement program in 1990, the Police Department also took responsibility for meter maintenance and repair. A supply, wash and shower room for the cell block is now used for the storage and repair of meter parts. The partnership of the Parking Enforcement Officer and the Mechanic, and the similar use of tools, would be best served if these two functions had neighboring work spaces. Page 5 of 9 CELL BLOCK AND BOOKING In 1956, prisoners were booked at the front desk, comingling with the public who might visit the police station. This practice continued after the renovations in 1970 because insufficient space was available in the police station for a booking room. In the early 80's, a small storage area (now used by the Animal Control Officer) was used for booking prisoners. This partial solution removed the booking process from public view but remained problematic when a prisoner became combative. TI-le small restricted area and close proximity to the front desk endangered officers and the public. When the police station was built in 1956, a basement space was provided for the jail cells. These were modular units that dated prior to the 1928 police facility. The metal cells with the traditional bars were disassembled and moved to the "new" police station. By 1980, the cell block was grossly out of code with modern detention facilities. The 1994 remodeled facility significantly improved the conditions in which detainees were held. However, the largest storage room in the police station was sacrificed for the "booking area" with the remainder of the space converted to store the 9 -1 -1 telephone and radio network. The location of the cell block made movement through the police station very difficult during a lock down. Stairwells. The Police station formerly had three stairwells. A centrally located stairwell was removed in 1970 to provide space for a juvenile detention room. Two stairwells remain — one in the rear of the building and one in the front. During a cell block Iockdown, the front stairwell is cutoff from the locker rooms and other basement areas. All pedestrian traffic is forced through the male locker room up the rear stairwell. If a public meeting is held, foot traffic must travel up two flights of stairs, across the second floor, and then down the front stairs to get to dispatch and the C.O. The ventilation of the booking — detention area has been dysfunctional since the 1990 renovation. The regulations governing detainees have also changed. Given the potential liability associated with detention, Lexington would be best served with a modern detention facility. Proper detainee handling starts with a secure sally port where detainees can be removed or placed in a cruiser safely. Direct access to a holding cell and processing area is then needed. For those who are not immediately released, three separate areas are required for detaining females, males and juveniles. All detention areas need storage for cell block supplies, shower, observation room, and an interview/bail /attorney consultation space. At least one and preferably two areas should have the recommended 80 square feet for holding juveniles. The minimum size for a cell is 48 square feet. The American with Disabilities Act requires one cell to be handicap accessible. EVIDENCE AND PROPERTY In 1956, a full size cabinet held the evidence required for court cases. In 1970, a small 5 x 10' room was built to accommodate evidence. By the early 1980's, a first aid room was retrofitted to hold lost and found property, and to hold evidence for crimes where there was no known suspect. In the early 90's, the accreditation office was converted to a small lab for fingerprint processing and fuming. The evidence and lab areas are grossly inadequate for the 2010 needs of the Lexington Police Department. Page 6 of 9 Today, legal mandates demand the secure storage of physical evidence. There are demands for refrigeration for blood and other perishable evidence. Drug evidence must be doubly secured as well as cash, jewels and other precious metal and stones. Vaults and temporary evidence storage are necessary. Although Lexington has rarely had issues of misplaced or missing evidence, the security of evidence is paramount to proving the proper chain of custody in court. Unfortunately, television and movies lead the less informed to believe forensic labs and crime scene processors can readily solve crime. The truth is that regional and state resources are overwhelmed with major crime evidence. The success of solving crime is often dependent on the local police department's ability to preliminarily identify fingerprint, tool mark, computer and photographic evidence. Property laws have also changed and presently require `found' property to be held 1 -year. Although small items can be stored and subsequently auctioned annually, the police station has no space for storing bicycles. After a few weeks at the police station awaiting an owner, bicycles are subsequently transported to a trailer located on Hartwell Avenue. This solves the storage problem but makes identifying bicycles and returning them difficult. RADIO AND 9 -1 -1 The nerve center of the Police Department is the computer hubs and radio base stations. In 2007, the Sergeant/Project room was taken so as to house the 9 -1 -1 and police computer network. This space is air conditioned all year round but was never designed to be a temperature controlled, fire resistant shell. The Police and Fire standby base stations (including UPS and battery back -up systems) are placed in 1994 in the basement behind the booking room. This space was never designed to be temperature controlled and fire resistant. This important equipment needs to be shielded from harm. RECORDS In the 1950s and 1960s, most police records could be stored in 5 or 6 file cabinets. But the laws changed requiring all government entities to preserve and keep public records. Presently, active criminal records (open court cases) are kept in the Traffic Office with a records clerk tending to the material, and backing up the traffic clerk to assist the public. Central records, located adjacent to the Chief of Police, have business records and criminal records that need to be held by statute. In the rear of the police station, second floor, there is archived and dead record storage. Unfortunately, the belief that computers would "lessen" the need for printed records has not come true. The archive room was separate into two working spaces in the mid 1980's. The second area now provides office space for the family services detective, school resource officers and the accreditation manager. Page 7 of 9 LOCKER ROOM The 1956 station provided 18" lockers for each officer, and only officers. Minimal additional space was added in 1970. During the 1994 renovation, the men's locker space was divided up and a woman's locker area and bathroom were built. This division of the existing space eliminated any spare space in the basement. The Men's locker room is not a true private space. Almost all travel to and from the Guard room, range, and garage is through the men's locker room. During a cell block lockdown, all traffic passes through the men's locker room. The men's locker room is also used to transport prisoners from the garage to the cell block. The equipment that police officers are issued in 2010 is two and three times more voluminous than 1956. Modern police lockers are 36" wide, with separate sections to store equipment, wet clothing, and business material. New lockers are also equipped with power so that radios and flashlights can be recharged. GARAGE FACILITY In 1956, there was a small garage used to service police vehicles. In 1970, the garage space was enclosed and is now used for the Mechanic's Office and supply room. The existing garage was added as a two -bay garage. Over time many additional pieces of equipment have been added and there is only room for one vehicle to park and/or be serviced in the garage. Storage of tires, oil, waste, wheel- balancing and air pressure equipment occupies much of the wall space. The "fleet" in the broader sense has grown. Radar trailers and message boards are stored outside the police station and suffer from inclement weather. There is no interior space to house a vehicle that may need to be held for evidence, or processed for fingerprints. RANGE The indoor firing range was built in 1956 in a sub basement. Once it was used as a fallout shelter and was equipped for a national emergency. The facility was not designed with the present awareness of chemical and airborne hazards. The ventilation was updated in 1970 but the facility is not suitable for officer qualification and retraining. It is presently used to house ammunition and the police range officers repair and inspect firearms in this area. Basic remedial training may also be done in this location. The Police Department also uses an outdoor range at Hartwell Avenue. The outdoor range has basic primitive equipment and a storage trailer is used to protect tables, targets and general supplies. Regional firing ranges are generally not available and are mostly privately owned. Local police departments have expressed interest in building/using a regional facility. .71- IN A discussion of the Police Station's evolution could delve into greater detail. It should be sufficient just too briefly comment on some additional areas: • No Elevator severely restricts movement a larger items and HP persons in the building. • Restrooms in the basement and 2 "d floor were not designed to be ADA compliant. Page 8 of 9 • Two custodial closets have been taken over. One to install AC to the dispatch center and the second for basement level storage. • With air conditioning added in 1970, two large storage areas were lost to accommodate air handling units. This equipment and the heating system are dated and inefficient. • Generators. The original generator dating to 1970 is still used as a backup. It's location and the need to vent the space compromises our ability to keep the radio room and booking area at the right temperature. The main generator is located outside and exposed to vandalism and natural hazards. • Storage and spare office space, as unglamorous as the areas may be, are no longer available in the existing police station. There is no room to add or expand existing services. • There is no fire suppression equipment in the building. STATISTICAL REPORTS It is difficult to compare statistics from 1956 to 2010. Different reporting laws apply, different crime data reports are kept, and even the definition of a crime has changed. In 1956, the Police Department investigated all accidents. Today, we may respond to many accidents but we need only report on those with over $1,000 damage or personal injury. The Uniform Crime Report given to the FBI is now completely different with the National Incident Based Reporting System. Also, traffic violations were deemed crimes through 1984. Now they are considered civil infractions. The early Town Reports define people charged but doesn't break down the types of complaints that did not result in an arrest or summons. Crime has also evolved. In the 1960's and 1970's, forced entry into homes and businesses were common to steal valuables. Today, a credit card and/or a computer are needed to steal property of greater value. If it is deemed necessary to compare statistical reports, we can delve into this analysis. It will be difficult to avoid a critique that the statistics, generated in different ways for different generational standards, can prove something other than what the person doing the analysis intends it to prove.

Corr Chief of Police '.Town of Lexington Police Department 1575 Massachusetts Avenue, Lexington, MA 42420 TEL: (781) 862 -1212 FAX: (781) 863 -1291 Staffing the Lexington Police Department December 1, 2010 By Chief Mark J. Corr Every police force is challenged with the increasingly difficult task of enforcing laws and of combating organized crime. Stated in simple terms the basic needs are: An earnest dedicated staff, paid salaries and afforded working conditions which insure holding good men [and women] and which permit a recruiting program competitive with non police job opportunities. Only by continually attracting young men [and women] of high caliber, who want to make law enforcement their life work, can we maintain the level ofpersonnel competent to do the job. 2. A training program which builds a staff of professionals who are smarter than the criminals that oppose them. Effective police departments are developed slowly, over the years. The great need is to keep ahead of our problems so that we can cope with them as they evolve. To do this, the police department must be kept staffed and trained in advance of actual need. It would be critically serious if this building for future needs were not a basic part of the police department's overall program. 3. Sound administration and adequate facilities of equipment and of quarters to supplement the efforts ofgood men [and women] carefully trained; a carefully thought outpatrol program which emphasizes mobility and fast action in getting to pressure points and which insures adequate patrolling at all other times. 4. Implicit in all of this is an acceptance on the part of the taxpayers that if the force is to be kept modern and if Lexington is to have the protection ofpeople and property to which the citizens are entitled, the town must be willing to pay the cost. We constantly strive for economy in our operation and for the elimination offat. We insist, though, that budget economies ought never forbid growth of the bone and sinew needed to serve an increasingpopulation and to handle law enforcement that is becoming constantly more complex. Town Report, Police Department, 1967 [includes amended text] 1575 Massachusetts Avenue, Lexington, MA 02420 Lexin ton Police SteRping to the Forefront. The opening commentary was written in 1967 and resonates as true today as it did 43 -years ago In the late 1960's and early 1970's, the Lexington Police Department established itself as a model agency that other agencies should emulate. Emphasis was given to hiring college educated officers, and then promoting life long learning. New programs were put in place for cringe prevention, traffic enforcement, and identifying and apprehending offenders. The Department quickly expanded from 36 officers in 1966 to 54 officers in 1975. During these years, the Department used FBI data to identify regional staffing levels. Lexington's population' in 1975 was 32,253 and the FBI reported that Northeast police agencies averaged 1.8 officers2 per one thousand people [suggesting that Lexington would have 58 officers]. The leadership of the Lexington Police Department has always been progressive, committed to serving the community as effectively and efficiently as possible. The patrol strategies were carefully defined many years ago, and have evolved with changing priorities. To their credit, the basic patrol strategies continue to prove very effective for Lexington. The basic components are: Four Patrol Sectors. Lexington is divided into four patrol areas. Like our new zip codes, Massachusetts Avenue and Bedford Street divides the Town east to west. We then use Grant Street to Waltham Street to divide the Town north to south. One officer is used to cover each sector. The two officers assigned east and the two officers assigned north work together as teams. We have made minor changes over the years, but these patrol assignments effectively balance the call volume for each sector and make it possible to respond to any residence/business in a timely manner. Center Foot Patrol. A walking beat covers an area from the Police Station to the Old Burial Ground (east to west) and roughly bordered by Forest Street to the bikeway (north to south). High visibility in the Center business district is an effective way to address traffic, parking and shoplifting problems, while also giving residents and business personnel a sense of security. Fifth Patrol Car — the "Floater." As staffing permits, a fifth cruiser or "floater" is assigned to a senior officer. The fifth car backs - up sector cars on a regular basis but also backfills open sectors. When one of the primary sector cars is occupied with reports, arrests, meal breaks or other administrative needs, the fifth car covers the open sector maintaining the integrity of the four sector plan. 1 1975 Annual Town Report, Town of Lexington, MA, page 6. 2 1975 Annual Town Report, Town of Lexington, MA, Police Department Report, page 49 Page 2 of 8 Patrol Sergeant. Street supervision is important. Given that Lexington has skilled patrol officers, Sergeants are there to help train, supervise and inspect day -to -day events. Sergeants guide officers as they wade through the complexity of police services and the extensive knowledge base that officers must be familiar with. The Department has an adage that it "takes five years for a patrol officer to be seasoned" because it takes this long to learn the fundamentals of the profession. It starts with officers completing a 24 -week police academy, 12 -weeks of field training, followed by a one -year probation period. Supervision during this training period and afterward reinforces each officer's job knowledge but also helps define the attitudes and demeanor expected of Lexington officers. Chan ,ginjz Priorities As of the early 1980's emphasis was placed on officers who were skilled "generalists" or, in other words, officers being retained within the patrol division and trained to handle different services. Briefly, here is a comparison of the Department in 1980 and 2010. In 1980: Staffing of 54 police officers 14 command staff 36 officers assigned to Patrol 4 officers assigned to the Detective Bureau Emphasis was placed on covering four sectors, a "fifth" car whenever possible. The Center and Desk were given high priority and were covered 2417. The Detective Bureau was primarily responsible for major case follow -up. Supervisor Plan Lexington has always emphasized the importance of supervision. The command structure has remained relatively stable over the years. However, the sophistication of police work has grown exponentially and most command staff officers are assigned other duties. They often serve dual roles covering grant writing, event planning, training coordinators and as traffic planners. The rank structure is: 1 Chief of Police 2 Captains; Administration and Operations 4 Lieutenants; Three night shifts and one day shift 1 Detective Lieutenant; Supervising the Bureau 3 Sergeants; nights 2 Sergeants; days; covering as Officer in Charge on weekends 1 Sergeant; Court Prosecutor Page 3 of 8 In 2010: Staffing of 47 police officers 14 command staff 28 officers assigned to Patrol S officers assigned to the Detective Bureau. The desk and center are covered Monday through Friday, days only. Sergeants have assumed the role of the fifth car or "floater" on many shifts. The four sector plan is also cut to three cars overnight from 4 a.m. to 8 a.m. when there are absences. Today, daytime Sergeants must supervise patrol officers, 14 school crossings, parking enforcement, animal control and numerous police detail sites. Since 1994, Lieutenants supervise the combined police /fire /9 -1 -1 dispatch center and, since 2003, Lieutenants are responsible for the walk -in public services previously handled by desk officers. Generalists versus Specialists Over the past 30 years, changes in the law have made it necessary to train "specialists." Juvenile laws, domestic laws, drug legislation, computer crime and even traffic regulations require officers to concentrate their efforts to stay abreast of these changes. Lexington has made adjustments to meet these needs. The Detective Bureau at one point expanded to 7 positions to meet community needs and expectations. At its peak 2 -years ago, the Bureau was staffed in the following way: Detective, days, major case Detective, days, Family and Community services Detective, nights, major case Detective, nights, drug investigation and vice School Resource Officer (formerly DARE) at the High School School Resource Officer at MMTech (not funded since 2009) School Resource Officer at Middle/Elementary schools (suspended since 2009) Many regional police departments have added traffic units to address the higher volume of traffic. There is also an increasing demand for crime prevention officers, crime and incident analysts, policy /accreditation managers, and computer crime specialists. With significant cuts to state funding, regional services are less reliable due to their staffing shortages and the heavy workload. Funding The funding for police services as with all Town services has been cut. Lexington has made important policy choices that have impacted the Department's staffing. 1990 A civilian Parking Enforcement Officer replaced one Center Officer 2002 Funding for one officer shifted to a grant to provide an SRO for the MMTech Page 4 of 8 2003 Override failure; funding for 12 officers lost 2004 Override restores funding for 7 positions but 4 Desk and 1 Center Officer (nights) eliminated 2004 A ninth dispatcher is added to cover late night shifts replacing the need for an officer after midnight on the desk 2009 MMTech ends funding for SRO position. 1 officer position eliminated. The Lexington Police Department is presently funded for 47 positions, down from 54. Injuries, Retirements and Military Service In 2009 and 2010, the staffing level of 47 officers was burdened further by the attrition of staff Four retirements, a long term injured on duty (IOD) and an officer activated for service in Afghanistan reduced the availability of officers to 41. In response to this staffing challenge, the Department suspended the Middle School SRO position, Drug Task Force position, job sharing, and the day -time desk position to backfill the patrol division. These additional officers reassigned to Patrol have helped to avoid `burn -out' of officers who are repeatedly taking overtime to backfill vacancies. How Should the Lexington Police Department be Staffed? There is no easy answer to this question. It all depends. There is no predictable formula as there is in fire services. Work volume and calls for service provide a baseline for need, but staffing is driven by policy decisions. Is the community best served if the police department reacts to service calls? Is the agency proactively seeking ways to problem solve? Or, is there a commitment to community policing programs that are labor intensive? The community, town leaders and the Chief of Police must establish priorities and then define staffing levels to meet these expectations. The following statement from the 1967 Town report remains true, "we constantly strive for economy in our operation and for the elimination of fat." This is not only an important goal for the Department but reflects public sentiment as demonstrated by recent national and state elections. If we were to use the FBI's officers per thousand standard, the 2009 figure for the Northeast Region, is 1.9 officers per thousand. In 2009, Lexington's population3 was 29,959 and this would translate to 56.8 officers. This FBI standard is an overly simplistic way of identifying staffing needs. In another example, we can assume that our neighboring communities are wrestling with the same dilemma of balancing budgets; health care, special education, capital needs and reduced state aid. When compared to similar sized towns in this immediate region, Lexington has consistently ranked in the lower third for police staffing. A work load study is a preferred method for weighing calls for service, traffic enforcement, investigative time load, report writing, leave time and much more. These studies however call upon management to make subjective judgments. How much time should be allocated for preventative patrol? How much for traffic? How much time for problem solving and 3 2009 Town of Lexington, MA, Annual Report, page 3 Page 5 of 8 community policing initiatives? These are policy decisions that can significantly change the work load figures. Here in Lexington, we asked recently: • Should there be a foot beat in Lexington Center? When? • Do we backfill for patrol supervision? • Should we cut back our four - sector plan to three cars after 4:00 a.m.? • Is overtime to backfill vacancies better than hiring new personnel and carrying the benefit and insurance costs as well? What Staffing Plan is 'Right' for Lexington? A basic response plan would provide service call coverage and little more. A more proactive plan provides enough officers to answer calls and provide adequate follow -up and simple problem solving initiatives. A community policing plan must carve out time where staff can engage in problem solving with equal importance as patrolling a sector. For example, a low cost initiative is our Child Safety Seat Installation program. Officers attend a 40 -hour training program to learn the proper installation of child seats. The initial inspection and installation of a car seat can take 1 -hour. The parent(s) are trained in the proper removal and reinstallation of car seats. It is difficult to schedule a series of safety seat installations if the officer is called away on a regular basis to answer calls. The Child Safety Seat program has resulted in more thank you notes to the Police Department than all other programs combined. Similarly, traffic programs are also difficult to administer at the patrol level. For example, a series of complaints of speeding motorists on Bow Street between 8:00 -10:00 a.m. requires an officer to have uninterrupted time to assess, evaluate and begin enforcement if needed. When needed, we must then be able to return to the area repeatedly to effectively stop the dangerous driving behavior. At the patrol level, officers often express frustration that their efforts are interrupted by service calls. Training Specialists then Rolling back into Patrol The Police Department hopes to start programs where Patrol Officers are provided training in specialized areas. Accident reconstruction, traffic enforcement, and /or crime prevention through environmental design are all important services to the community. Giving officers the chance to perform these assignments is a career opportunity. By rotating officers through these positions (1- to 2 -year tenures), the Department can roll back into the Patrol Division trained officers. Rather than have one officer with 5 -years experience and superior skills, five officers can be trained in the same period of time and given a better understanding of crime prevention and/or traffic services. These five officers eventually influence other officers on their shift, and the overall skill level in the Department is enhanced. Page 6 of 8 What Does it Take to Staff the Police Department? The answer rests with how many hours does it take to cover a sector? 24 hours times 365 days — 8,760 hours in a year Secondly, how many hours can any one officer work? Step 1: If never absent, an officer can work 1,947 hours per year Step 2: But, officers receive vacation leave, get sick or injured, attend training and court, jury duty, military service or take personal days. If the average officer missed approximately 38 work days or 304 hours, then he or she can work 1,643 hours per year. Doing the math, it therefore takes 5.33 officers to cover one sector 24- hours, 7 days per week. In our basic patrol plan, we cover: 4 sectors 24/7 — 21.32 officers Weekend/Fifth car coverage = 2.03 officers Center coverage, days 1.27 officers Desk coverage, days = 1.27 officers In summary, to cover the basic jRatrol plan for Lexington takes 25.89 officers. Presently, we have 28 officers in patrol. This gives us a buffer of a little more than two officers. The formulas above are subject to change. It is foreseeable that the demand for training officers will continue to increase resulting in more patrol hours lost. In addition, from 2009 to 2010, the Department was down six officers due to injuries, retirement, officers in basic training, or activated to serve in the armed forces. The reserve of two officers was insufficient to provide coverage for our basic patrol plan. Preferably, a more proactive patrol plan would give us the reserve force necessary to backfill for retirements and long term absences. Given the lengthy time it takes to train new recruits, the lack of a reserve force makes it necessary to suspend important programs. One example is that the Department has four officers eligible for activation for military service. Given national policies, it is very likely these officers will be deployed time and time again. It is our preference to cover the fifth car days, evenings and weekend nights. A Center officer is frequently requested for evening shifts and on weekends, particularly in the summer. We also have a need to cover the Desk from approximately 8:00 a.m. to 8 p.m. weekdays. Although not included in this formula, we feel strongly that an officer should be reassigned to the Middle Schools as a resource officer. UItimately, a more robust community policing plan should earmark officers for specialized services (traffic programs, crime prevention, statistical analysis, policy development, accreditation, computer crime). These officers must have schedules that permit them to go Page 7of8 where they are needed to identify problems, work through solutions, and follow -up. These officers serve the dual function of being immediately available to assist the patrol division anal /or backfill positions due to long term absences. CONCLUSION Whereas this report focuses on staffing by police officers, it is important to emphasize the hard work of all Police Department employees. With 16 crossing guards, 9 civilian dispatchers, 4 administrative personnel, a parking enforcement officer, animal control officer, mechanic, police cadets, auxiliary and traffic officers, the Police Department has the skilled personnel to meet many community needs. It is also important to note that all Departments in Lexington have wrestled with program improvements and staffing shortages. Public services in Lexington are outstanding and this is a measure of the dedication and commitment of good people. It has been my experience that the officers of the Lexington Police Department have excelled at their duties year in and year out and that there is a measure of frustration that police leadership has not effectively convinced the community of our needs. It is my goal to engage Town leaders, work cooperatively with the Senior Management Team, and promote the advantages of a Police Department that can provide all the basic services while also engaging in progressive problem solving community policing initiatives. Restoration of 2 -4 police officers by 2020 will improve services to the Town of Lexington. It is only fitting to end with: Our purpose always, is to serve Lexington's [30, 000] citizens with all the competence, courage and integrity that we possess. We look hopefully forward to a year of continued public awareness of problems still to be overcome and of cooperation from all citizens in helping meet those problems. To a town which has always refused to tolerate a second rate police department, we pledge our best efforts, as we have in the past, to provide Lexington with the physical security and the peace of mind that can be afforded by no other agency.

LEED AP Donham & Sweeney Architects 68 Harrison Avenue Boston, MA 02111 Reference: Lexington Police Station- Lexington, MA Existing Conditions Study Dear Jeff- This letter summarizes our findings regarding the present condition of the structure of the Lexington Police Station on Massachusetts Avenue in Lexington, Massachusetts, and our recommendations regarding future uses of the structure. These observations and recommendations are based on information provided to us by your office, as well as, our field observations of May 6, 2010. There are copies of the original building's Architectural and Structural drawings, but the quality is poor, (they are photos of the original old documents and most of the text is not legible) making them useful for determining how the building is framed, but not much else. As such, we have a reasonable understanding of how the building is framed. Since the text of the original drawings is mostly illegible, we are unable to determine exact member sizes, and as such we are not able to verify load carrying capacities of specific members. Our field observations were only visual surface observations, we have not cut any holes in building finishes, to verify structure, nor have we done any testing to determine the structures underlying condition. Existing Conditions On May 6, 2010,1 toured the existing Lexington Police Station Building with Brett Donham of Donham & Sweeney Architects, the project architects and Chief Corr, of the Lexington Police Department. The existing Lexington Police Department Building is a three story structure, (including walkout lower level), with a small sub basement (used as a firing range) on the north side of the building, partially outside under landscaping and an exterior entry ramp and stair. The original building was constructed in 1956 to house the police station on the lower floors and town offices on the upper floor. The structure underwent an interior renovation in 1996, limited to the dispatch and cellblock/booking areas. There is also a small single story maintenance garage addition on the east side. The entire building is now occupied by the police department. The structure has a basic Z- shape with the small addition at the rear of the lower level used for vehicle maintenance. The sub basement firing range and the lower level, which houses; locker rooms, cells, and mechanical/storage areas, is constructed of reinforced concrete. The basement floor is a concrete slab -on- grade, and the foundations consist of concrete foundation wails and spread footings. The main floor, framed with reinforced concrete slabs and beams, and supported on reinforced concrete columns, is where the department has meeting rooms, 911 dispatch, and other public access functions. The second floor is used for offices, and is framed with open web steel joists and concrete on form deck supported by steel beams with steel pipe columns from the first floor on the interior, and on exterior masonry ROOMS & GUARRACINO, LLC Page 2 bearing walls on the `building perimeter and at the stair wells. The roof is gabled, framed with a series of steel trusses, and beams that form the valleys where the gables intersect. Gypsum panels spanning over the trusses with slate roofing complete the roof. The exterior walls and stair well walls are mutli -wythe unreinforced masonry bearing walls, which also act as shear walls to provide lateral stability to the structure for wind and seismic loads. The majority of the interior partitions in the building are unreinforced CMU. These interior CMU partition walls may help in the structures lateral load resistance, but do not appear to be original to the building and therefore may be removed and /or modified in any renovation. There are some non -load bearing CMU partitions that do not connect floor to floor, which will have to be braced or removed (see renovation discussion below). Since, due to the poor reproduction quality, we are not able to make out specifics from the structural design documents for the building, it is impossible for us to determine precisely what live load a specific member may be designed for. However, the original structural drawings have notes indicating that the floors are designed for a live load of 100 psf. Based on what we are able to glean from the drawings, our observations of the actual framing, and the present condition of the structure, it appears that the floors were designed for the appropriate code mandated loads for assembly uses. The roof design also appears to have been done for the code mandated snow loadings of 30 psf, While the structural framing for most of this building is not visible, as ceiling finishes cover the framing, there is no evidence of major structural distress. The floors show no evidence of concrete cracking or other structural problems. There is no evidence of significant foundation settlement or foundation wall cracking. The interior masonry partition walls generally look good, with only a few areas showing some minor cracking. The exterior of the building looks good, with only some very minimal cracking of the exterior brick masonry, and areas that need repainting. There have apparently been some areas of roof leaking in the past, which may be a concern, as gypsum planking deteriorates structurally when exposed to moisture over time. Generally the building structure appears to be in good condition for its age and very well maintained. Addition/Renovation Feasibility It is our understanding that you are interested in possible options for renovating and adding to the existing structure, in an effort to add needed space, and to accommodate changes in program. Our review of the existing structure indicates that minor renovations to the existing structure are possible, as long as the exterior load bearing masonry walls and the load baring masonry walls around the stair wells are basically left in tact, as they provide the lateral bracing system for the structure. Large - scale removal of these shear walls would violate the building code provisions against weakening an existing building's lateral system, which would necessitate a seismic upgrade to the entire structure, which we do not recommend as it is usually very difficult and costly. Turning exterior windows into doorways by removing the masonry below the sill is not a problem, but significantly increasing the width of a number of exterior openings or combining openings by removing masonry jambs may trigger an upgrade. Our analysis of the lateral loads on the structures as required by the Mass. Building Code in Section 3408, and our discussion with you about renovation, options, indicates that structural work proposed would be classified as "Level 1 Work ". Under "Level 1 Work" the exterior shear walls must be left intact, while the interior partitions are not structural and may be modified or removed, Any additions attached directly to the existing structure would have to be kept small, so as to not trigger a complete seismic upgrade of the building. (see discussion below) A small roof or canopy would be small enough so that it could be connected directly to the existing structure, and not pose any structural complications, Any larger addition would need to be separated from the existing ROOME & GUARRACINO, LLC Page 3 structure by an expansion joint. Under the present seismic code expansion joints generally need to be 2" to 3" wide for each level above grade. (The roof of a two story building would have a 6" to 9" joint.) Mechanical upgrades to the building are also feasible. New openings required for ducts, piping, etc. in the roof deck or in the concrete floor slabs can be accommodated as long as the openings fall between the existing framing members and do not interfere with the framing. Small openings, 12" or less, can be accommodated with out any additional framing, Larger openings may need some supplemental framing between primary structure. New maj or openings that would interrupt existing framing can also be accommodated by adding new framing if necessary. Generally, minor structural changes required to add or modify stairs, elevators, add mechanical openings, or add roof skylights are fairly simple, and do not have a major impact on the existing building structure. However, any additions and alterations to the existing structure must be kept to less that 10% of the existing building's area and mass, or a major seismic upgrade would be required by the State Building Code. Such an upgrade to the structure would be prohibitively expensive, and must be avoided. This is one reason why any proposed new additions will have to be separated from the existing building structure by an expansion joint. Any new structure could then as large as desired and still be in accordance with the latest codes. For cost and flexibility reasons, we would reconumend that any new addition be framed in structural steel, with a slab -on- grade for the lowest level floor, steel beams and concrete on steel deck for all framed floors, and steel beams and steel roof deck for the roof. Braced frames of structural steel would be the least expensive system for providing stability for wind and seismic loadings. Based on the information that we were able to glean from the existing drawings it appears that any new foundations would be spread footings. Other structural systems and building types are possible and can be properly vetted once an actual building layout is proposed. Based on our review of the existing building's drawings and our field observation, it appears that there are number of the masonry inflll walls that are not tied or braced at their tops against falling over in a seismic event. We understand that the intent is to remove most of the interior non - bearing masonry partitions, however, any such walls, not removed in the renovations must be addressed. The State Building Code requires that the tops of all masonry walls be tied to the structure to prevent their falling over, and that this work be performed as part of any-major renovation or alteration to any existing structure.

Therefore we recommend the following HVAC system replacements: Heating System: The existing hot water boiler system is inefficient in comparison to today's energy efficient heating systems. In general, the existing hot water piping distribution system has GARCIA • GALUSKA ! DESOUSA Consulting Engineers Inc. Lexington Police Station Lexington, MA Existing Conditions Systems Report J #640 017 00.00 L #30750/Page 12 /June 23, 2010 exceeded its useful service life and will continue to require increased maintenance and repair costs. We recommend that the existing hot water boiler is replaced with a high efficiency gas -fired condensing hot water boiler plant, consisting of boiler, pumps equipped with VFD drives, DDC controls (including outdoor air reset) and accessories. A new steel/copper piping distribution should be provided to replace the existing piping. The piping should be designed and installed in a manner which provides improved zone control capabilities, two -way modulating zone control valves and remote wall mounted thermostats. The basement, first and second floor areas of the building should be heated by terminal hot water heating systems. Energy efficient heating systems such as fan coil units could be installed to replace the existing hot water radiation heating equipment as part of a building renovation project. Fan coil units could also be used to provide air conditioning to areas utilizing the same piece of terminal equipment. The sally port/garage unit heaters should be replaced with new hot water heating unit heaters. Ventilation: We recommend that a new mechanical ventilation system be designed and installed to provide year -round ventilation for the building. It is recommended that a new ventilation system be provided with energy recovery and supplemental heating and cooling capability. This would allow the system equipment and associated ductwork distribution system to be sized based solely on ventilation and make -up air requirements. This approach would result in lower first installed cost, improved energy efficiency and improved thermal comfort and indoor air quality. Air Conditioning: The existing building air conditioning system consists of multiple air handling systems and ductless AC units. The majority of the air handling units have exceeded their expected service life. While the first and second floor air cooled AHU associated air cooled condensing units are in good condition, the units have lower energy efficiencies than commercially available today, and would not likely be compatible with the proposed central station air handling and cooling plant equipment. The existing ductless AC unit systems could potentially be re -used to serve the AC needs of dedicated areas of the building or could potentially be used by the Town for another building. We recommend that a new energy efficient air conditioning system is installed. As described above, a hydronic heating and air conditioning systems such as a fan coil unit system could be utilized to provide both heating and cooling to the building. GARCIA .

The report must also address the critical issues with the building and develop a list of "must do's ". The fire Chief is satisfied with the space needs analysis contained in the previous study. D &S to confirm the structural and MEP analysis contained in the previous study. The Police Station is a study; the Fire Station work is to proceed through schematic design. The combined police /fire or public safety building is a comparative cost study but should include parameters for site selection. One site mentioned is on Worthen Road. D &S to redraft their proposal for services, taking into account the use of the previous study, and adding fee and schedule components. [Done 14 January 2010.]The goal for the schedule will be to hold a public information meeting in early June and have the final study ready for vetting by Town boards in the early Fall. The PBC wants to bring the projects to a Town Meeting in late October or early November. D &S is not to start work until there is agreement on scope, work product, schedule and fee. The PBC meets the second Tuesday of every month.

Donham distributed copies of the Draft Space Needs Report for the Police Department. Questions were raised as to whether some of the spaces described were too generous. D &S was asked to compare Lexington's space needs with other towns. The generator[s] should be secure. A space layout for the Fitness Room was requested. The Police Department was asked to prioritize their space needs and explain how their operations will be improved by the space increases. Chief Corr will be setting up an internal review of the Draft. B. Donham reported that a contract for a topographic and utility survey of the fire station site had been let and the survey was expected by May 5 or b. The Draft Zoning Analysis showed that several Variances and Special Permits will be needed. A meeting will be set up with Dave George to review the Draft including whether the fire station is in an historic district. Site plan options for the Police Department expansion were reviewed. A decision was made that this project would not include moving the White House to make room for the Police Station. D &S was directed to a parking expansion layout prepared by David Handlin. The project is generally on schedule; the site analysis is ahead of schedule while the analysis of the existing buildings is behind schedule. The next meeting is May 11.

Patrick Goddard; Carl Oldenburg; ebrown @prellchil.com; jhimmel @mit.edu; peter.johnson @skanskausa.com; rfperry @comcast.net; brucecreager @comcast.net; Mark Corr; William Middlemiss Subject: Monitoring wells At the last PBC meeting 1 was asked to dig into the monitoring well issue for both the Police and Fire Facility. What I have discovered is below: Police Station Resource: Mark Corr Chief of Police There are two or three monitoring wells behind the police station. The first is near the overhead door that serves the Police Mechanic. The second is near the parking lot end of the adjacent driveways and the third is moving the rear toward the parking spaces and the generator. These monitoring wells were installed circa 1999 when the underground gas tank was removed. There is still am underground fuel oil tank near the existing generator location. Resource: John Livsey, Town Engineer These monitoring wells are under the observation of Lexington Engineering. John anticipates that they will be able to file the appropriate paper work with DEP to close out these monitoring wells within a year's time (fingers crossed) It is anticipated that the monitoring wells will be gone by the time any type of construction activity were to begin. Fire Station Resource: Bill Middlemiss, Fire Chief There are numerous monitoring wells ( +/ -6) on site with many others on adjoining property. These monitoring wells were installed after the underground contamination / release was discovered at the shell station across the street, circa 1993. There are numerous contracts and documents between the Town and Motiva (parent company to shell) These monitoring wells are tested periodically and monitored for contaminants. These monitoring wells are handled by Sovereign Consulting, Mansfield, MA (presumably hired by Motiva) There is a sump pump in the basement of the Fire station due to high groundwater problems. Because of this water is sampled from this sump pit and tested for contaminants Water from the sump pump is piped outside to a filter system and piped to leaching tanks in the rear of the lot. Resource; Discussion with John Livsey and Dave Cannon, Town Engineer and Asst. Town Engineer John and Dave were concerned that the obligations of Motiva for monitoring had term limits and may be ending soon. Dave advised that the Town had a consulting engineer do some work on 6/8/2010 Page 2 of 2 this matter some time ago and I requested to speak with him. Resource: Rick Wozmak Enviro[o is Consultant Hired by Town Rick advised me that Motiva is required to be onboard until all concentrations being detected drop to acceptable levels. I do not currently know what the status is of the testing results. Rick stated that the contaminants are petroleum based and cleaning solvents. Rick has a proposal pending with the Town Engineers office for the filing of DEP paperwork regarding the ongoing responsibilities on site. Rick advises that not all monitoring wells are still active and this should be documented from the monitoring agency and Motiva would be responsible for removing them. Rick indicates that if we choose to renovate or add on the building that Motiva would work with us to relocate monitoring wells as necessary. Resource Larry Heinlein, Sovereign Consulting. Consultant for Motiva talked with Larry from Sovereign, whose company is responsible for taking the samples and making observations at the monitoring wells. Larry states that Monitoring well 8 and 10 are likely expendable and could be removed, and that others are still needed. Larry indicated that he believes that all parties would cooperate in relocation of monitoring wells if needed, although the issue of associated cost would have to be determined. Larry indicated that the water testing in the sump pump and the associated filter system and leaching field would not be required if a anew or renovated plan did not have groundwater leaking into the basement and there was no sump pump, Marie W.

Donham described the results of the structural engineering study for both buildings, a copy of which has been given to M. Barrett. Both buildings are in non - compliance with the seismic requirements of the new Building Code. Retrofitting both buildings with seismic resistant structures is very expensive. To avoid that cost, any addition must have a 3" wide soft joint with the original building and new openings in the masonry walls must be very limited in size. The structural slab in the apparatus room is failing, has sagged and has cracks that extend through the slab. The structural engineer believes it will continue to function at least to mid -2011 and perhaps beyond, but is unwilling to predict when it will fail to the extent of putting the apparatus at risk. He said "something needs to be done soon ". J. Shaw presented two sets of plans for the Fire Station. One is a renovation/addition and the other is a new building. These plans resulted from 2 meetings with the Fire Chief. J. Shaw described the constraints offered by the existing building and the increase in floor area resulting from trying to reuse the building. He also described the significant traffic difficulties with all apparatus trying to exit or enter via Camilla Avenue onto Bedford Street. The Permanent Building Committee offered the following comments; • In the parking table, indicate the number of existing spaces as was done with the Police Station • In the new building design try to avoid the small setbacks at the second floor because of the extra cost • In the new building try to put the stairs in -board so exterior walls are freed up for windows 68 Harrison Avenue 4 Head Tide Church Rd B osIon MA 021 1 1 Post Office Box 265 617 423 1400 Alna ME 04535 donharnandsNwene� coot 2 0 7 5 8 6 6 0 0 0 B. Donham presented one set of plans for the Police Station. These plans grew out of extensive consideration by Police Department staff and 2 meetings with them. A copy of the Sixth draft of the Space Needs Program was distributed. The program area has grown from 24,450 SF on 4/13110 to 28,126 SF in the Sixth Edition. increases were primarily in the Garage, the Sally -port, the Lobby, and the lockers [as a result of moving from 30" to 36" lockers and increasing the number of lockers]. The Police Chief said the Dispatch needs to be larger, and secure space, preferably indoors, needs to be provided for 2 emergency generators. He also said he needs a serviceable range that is large enough to train on; the present one is too short and an outdoor range, reproducing real -world conditions, is preferred. The present range is contaminated with lead, he said. The Committee instructed D &S to construct the base building pricing with refurbishment of the present range in the building plus a new indoor /outdoor rang at Hartwell Avenue. An alternate should include a new indoor range at the Police Station. Other comments from the Permanent Building Committee; • Document the gross to net area for each building • Provide cost estimates and elevations at the next meeting on 7/13. The estimates are to include plans with and without seismic upgrades as well as the costs to extend the useful life of both buildings by 10 years. MEP narratives will be needed as well • The 7/1' ) meeting will include members of the HDC on an informal basis • There will be a special meeting on 7/27 that includes the Capital Expenses Committee and possibly a representative of the Boar of Selectmen -2- s9r, I :-� 7� � , ?;, , Lexington Police & Fire Station Study Meeting Notes 27 July 2010 Page 1 of 2 Attending: Jonathan Himmel Chair, Permanent Building Committee Eric Brown Permanent Building Committee Bruce Creager Permanent Building Committee Richard Perry Permanent Building Committee Carl Oldenburg Permanent Building Committee Chief William Middlemiss Fire Chief, Lexington Fire Department Chief Mark Corr Police Chief, Lexington Police Department Patrick Goddard Director, Department of Public Facilities Mark Barrett Project Manager, Department of Public Facilities Ted Edson Lexington Capitol Expenditures Deborah Mauger Lexington Board of Selectmen Alan Levine Lexington Appropriations Committee Carl Valente Lexington Town Manager Brett Donham D &S Jeff Shaw D &S Distribution: All present, plus Peter Johnson Permanent Building Committee Nick Derr D &S Avi Shoss D &S File: 0907:2.2 Next Meeting: 8/10/2010 • The PBC and D &S- architects made a joint presentation to members of the Board of Selectmen and the finance Committee. The report was a progress report that described the scope of the effort and the findings to date. The BOS and the Fin. Com. were asked to provide guidance regarding some choices and issues presented. • Comments received included; • Be clear about the amount of increase in space • Be clear about the process that generated the Space Needs; reference industry. standards wherever possible • Compare the space needs for Lexington with other comparable towns • Provide a comparison of requested space to existing space for the Fire station [the police Station tabulation already does this • Describe the inefficiencies or compromises resulting from adding onto the existing buildings compared to building new and, separately, resulting from the initial decision to not seismically upgrade the existing buildings • Provide a cost estimate to seismically upgrade the existing buildings • There is a major policy issue for the Town regarding whether or not to seismically upgrade both buildings. o Define the points of urgency; what needs to be done in the short term? What happens to each of the buildings if the Town waits 5 years, or 10 years to renovate or replace there? o Fire Station Option A; doesn't look as if thee is enough room for apparatus to back in. o Public Safety Building; the land acquisition cost in the cost estimate should include the corner lot. o What is the nature of the right -of -way [Camilla Place]? Who owns the underlying land and who has rights to use the ROW? D &S to correct the PowerPoint presentation and send to Mark Barrett.

The table of square footage comparisons prepared by D &S was reviewed. The PBC asked that Yarmouth and Lexington Actual be removed, leaving Lexington Existing, Lexington Programmed, Hudson, and Franklin. The PBC asked that D &S not show the complete Iist of spaces in the comparison chart, but rather, bunch them into categories. J. Himmel will determine the category groupings and provide that information to B. Donham. B. Donham described the work needed to both buildings in the next 5 to 10 years. The Fire Department apparatus room slab needs to be shored up. D &S doesn't recommend replacing it since the ultimate solution D &S recommends is to replace the building. Other work is identified in the engineering reports and consists of replacing equipment that is or will wear out. M. Barrett reported that the cost identified 2 years ago to replace the slab was $1 M. Comments from PBC and Selectman Burnell included; -we need to justify why the size of the two buildings needs to be doubled -don't do any further work on a combined Fire and Police Station [Public Safety Building] -can offices be combined to create more flexible space? -work on only the Fire Station for now, but don't do any more design work -the existing floor area for the Fire station should include the trailer housing the Fire Prevention Bureau -a site meeting with the Selectmen will be scheduled; updated comparative information is needed for that meeting. -D &S to get staffing levels for both stations at the time they opened. 10/29/2010
