The project is designed to replace the existing school. The project schedule includes construction of the new school while the existing school will remain open for classes. Following the completion of the new school, the existing buildings will be demolished. Agencies with jurisdiction: None Summary of Primary Impacts: • Earth Site is relatively flat in the construction area. Steepest portion of site is 50%. The portion of the site along the front property line has a slope of approximately 15 percent. The front yard will have improvements for curb, gutter and sidewalk as well as the planting of front yard landscaping. Approximately 4.5 acres of the site along the south and west sides include native vegetated slopes in excess of 20%, which will not be disturbed as a result of this project. Any disruption of the site where slopes are greater than 20% requires compliance with the City's Sensitive Areas Ordinance (TMC 18.45). Any trees removed in said slope will require compliance with the City's Tree Ordinance (TMC 18.54). Approximately 10,000 cubic yards of cut and fill will be required to create the new building site. Erosion control will occur during clearing of site and building construction to include a sediment ponds, fabric fencing and trenching. A Land Altering Permit for movement of earth in excess of 50 cubic yards is required. 22% of the site will include impervious surfaces. • • E98-0025 - Tukwila School 5939 S. 149th December 30, 1998 • Air Dust will be generated during construction, with watering to control dust. • Water Surface water runoff from impervious surfaces will be collected and treated on-site prior to discharge to off-site systems. Runoff due to high water table and collection of water draining from off-site may occur on site. A catch basin system will be used. The storm drainage system must comply with the city's storm water management ordinance and the King County Surface Water Design Manual. For water quality and on-site detention, a Wet Pond and Bioswale will be the dominate features, both located along the east and southeast portion of the site. Some grading will occur to improve the function of the above ground system. An off-site analysis including upstream and downstream drainage with retention analysis may be required, as the drainage may filter into existing wetlands and into the Gilliam Creek watershed. • Plants In addition to the native and vegetated slopes previously mentioned, there are planted grasses for play fields and ornamental vegetation around the site. The bulk of the existing landscaping will be removed and a new landscape plan will be submitted as part of the final approved plans. The landscape plan must be approved as part of the Conditional Use Permit requirements. The bioswale and wetponds will have landscape elements to screen visual impacts and impede physical access. • Animals No known impact. • Energy/Natural Resources Electricity and/or natural gas will be used to heat proposed structure. The structure must comply with the Washington State Energy Code. • Environmental Health No known environmental hazards. Noise will be generated both during construction period and from traffic after project is completed. Construction activities must comply with Tukwila's Noise Ordinance (TMC 8.22). A demolition permit from the Puget Sound Air Pollution Control Agency (PSAPCA) will be required, which may include specific requirements in case of on-site asbestos removal during the demolition of the existing structures. E98-0025 - Tukwila School 5939 S. 149th December 30, 1998 • • • Land/Shoreline Use The site is located in the Low Density Residential (LDR) zone. The site also includes Public Recreation Overlay zoning classification, regulated under TMC 18.42. A Conditional Use Permit is required. A variance will also be required, as portions of the structure are in excess of the 30 foot height maximum for all uses in its zone. Approval of a Lot Consolidation will be required prior to the issuance of any Development Permits. • Housing No known impact. • Aesthetics The existing structures will be removed. Approval by the Board of Architectural Review for this project is not required, although aesthetics may be part of the Conditional Use Permit approval process. The project will require a variance, as portions of the building exceed the 30 foot height limit for uses in this zone. The predominate building materials include a Standing Seam Metal roof, Concrete Masonry Unit (CMU) base and Fiberboard exterior walls. A landscape plan approved by the Planning Commission is required. • Light and Glare A lighting plan has been submitted as part of the Conditional Use Permit. Pedestrian, parking and architectural enhancement lighting will be included. Shields and/or reflectors will be used on parking lot standards to avoid off-site impacts. Minimum candle power requirements may be needed to ensure minimal off-site glare. Adherence to Crime Prevention through Environmental Design (CPTED) standards for placement, type and intensity of lighting may be required to minimized possible off-site impacts and to ensure lighting adequately lights the site and reduces unlit or improperly lit areas of the site. • Recreation The existing fields at the school will be rehabilitated and restored. The playfields will be dual use for Soccer and Softball. The files will be designed primarily for use of the school but may be used by School District sanctioned users and events. E98-0025 - Tukwila School 5939 S. 149th December 30, 1998 • • • Historic/Cultural Preservation No impact. • Transportation 64 parking spaces are proposed for the school. In addition, bicycle parking stalls for both students and staff will be required. A hauling permit for removal of debris following construction will be required, as well as for construction vehicles and related activities. A Transportation Management Plan will be required to address transportation impacts as a result of the construction of the new school. A traffic impact analysis has been submitted along with grading and paving plans. A traffic study may be required • Public Services The facility may require fire and police protection as well as emergency services. CPTED standards concerning lighting, off-site visibility and access to the school have been reviewed and addressed by the Tukwila Police Department as part of this review. • Utilities The site is served by the City of Tukwila Sewer and Water utilities. Electric, gas and telephone services will be secured Recommendation: DNS • City of Tukwila John W.

Included within and noise control recommendations. Recommendations are based upon information found in the DD level documents. RECOMMENDATIONS Architectural Acoustics Architectural acoustics consists of control of sound between spaces, and creation of desired acoustical environments within spaces. Classrooms In typical classrooms, floor carpeting and lay -in acoustical panel ceilings (minimum NRC 0.6) provide sufficient sound absorption for controlling reverberation and maintaining speech intelligibility. Classroom finishes which have significantly less total sound absorbing capacity, for example where carpeting is omitted, should be augmented with acoustical wall panels. In the Art & Science classrooms where hard. finishes are the norm, higher noise levels are typically accepted, therefore augmented absorption is can be omitted without causing unexpected conditions for the instructors. Music The most common deficiencies in a school music rehearsal room are insufficient "acoustical volume" for the number of students using the space, inadequate ceiling height and inappropriate surface finishes tocontrol ic an reverberation and heigh and dof 18 8 feetusion f are e sound. A volume of 500 cubicp considered minimum to adequately diffuse the sound generated by an instrumental group. Rooms that are too small would result not only in lack of audible interaction between the students but also in higher sound pressure levels which could be potentially damaging to the hearing of the students and music instructors, as well. Controlling maximum sound level exposure is a requirement to meet standards under WAC 246-366-110. ion and The Music Room acoustical treatment is designed to to musical sound.control To accomplishtth s, the produce uniform response of the RECEIVED Acoustical & MechanIcaingineerIng Consultants 919 NE 71st Street Seattle, Washington 98115 tTO/Z00 L HOU ILL3SSV DEC 15.1998 COMMUNITY DEVELOPMENT Phone (206) 524-0593 Fax (206) 524-0630 6TS6 OtC 90Z %V3 OTA7T 96/ST/ZT Tukwila; Elementary School Novembee.0, 1998 Page 2 Music Room should be designed with a combination of reflective and absorptive .elements over the most of the wall, ceiling and floor surfaces. Recommended Acoustical Treatment Ceiling. Suspend a ceiling grid below the structure, maintaining as much height as practical. In approximately 60% of the total surface area, place a fissured mineral fiber tile minimum NRC 0.60 in the grid. The remaining area should consist of either gypsum board panels cut to fit the grid or lighting fixtures. Either parabolic lenses or flat Tens surfaces on the lighting is acceptable. Distribute the "hard" and "soft" surfaces evenly around the room. Walls: Acoustically absorptive panels should be alternated on all wall surfaces, covering about 40 to 50% of the total wall area. We recommend full wall height (or nearly so) for the absorptive panels. If desired, absorptive panels can be located some height (not more than 2 feet) above the floor to reduce damage and held below the ceiling by 1 or 2 feet. Less coverage of the walls may be adequate reverberation control and can be evaluated as the design scheme for the room progresses. Absorptive wall panels should consist of 2" thick panels with a core of glass fiber, minimum 0.80. Panels should be covered in an acoustically porous covering. A perforated covering offers excellent abuse resistance, providing that the NRC is maintained. Distribute evenly around the room. Recommended products: • Rebound series panels by Wall Technology. Represented by Schwarz & Associates, (425) 277-0631 • ALPRO perforated metal panels with 2" fiberglass filling, 3 psf density. Represented by William Plunkett Company, Seattle, WA, (206) 322-0250. Hard chalkboards, etc. should be angled out at the bottom 100 to direct the reflected sound into the ceiling. Floor. The floor should remain hard; vinyl, wood or concrete. Multi -Purpose Room Absorptive treatment is essential in this area to control noise levels during lunch and other times when Targecrowds will be gathered. This is not the best approach during a performance. However, there will be a sound reinforcement system in this area which will augment the sound. The room may sound somewhat dead for music, but intelligibility of the spoken word should be good. rr h (' GREENBUSCH G To 11 C) 919 NE 71st Street Seattle, Washington 98115 • Phone (206) 5240593 • fax (206) 5240630 VTO/C00)J HMV IZL3SSVfi 6TS6 OVC 90Z IVA TT:VT 96/ST/ZT Tukwila Elementary School November 6,.1998 Page 3 Wood ceiling is currently scheduled in the Multi -Purpose rooms. Since the wood ceiling system is desired architectural design of the space, we suggest a few options which allow keeping this aesthetic quality. Suggested products: • Wood Grill by Pacific Wood Systems (if this product selected, we will advise regarding type to be used), represented by Andy Schwarz, 425-277-0631. • Louver Wood Ceiling by Conwed (rail height should 1-1/8"), represented by Gunnar Fortland, 503-228-07028. • MonoCell by Ceiling Plus, represented by Gunnar Fortland, 503-228-07028. 1" thick black -faced ductliner should be placed above the suspended Wood Grill Ceilings. In addition tothe ceiling treatment, wall absorption is desirable to control reflections. This is particularly important on the wall surface eopposite s the bac"stato ge" location when the space is used for performances to control he lecturer or performer. We recommend that absorptive panels be located on the north wall of the room assuming tloc tt hou of the probablee most latform location, snot defined we would platform is at the south wall. If the p recommend a uniform distribution of the acoustically absorptive panels over the walls in the form of 8 feet high and 4 feet wide panels located at about 3 feet above the floor and 4 feet apart. Library the ceiling in the If the Reading 'room is likely to be an active, instruction space, space should be absorptive. This will be particularly critical in any story telling area. The same kind of absorption system (wood grill with black -faced ductliner above) as that recommended for the Multi -Purpose room can be used in the library. The stacks of books will provide adequate diffusion along the lower level. No additional wall treatment is required. The floor in this area should be carpeted. Gymnasium The reverberation in the gymnasium can be controlled through the placement of absorptive treatment on the ceiling surface. Controlling reverberation will improve the ease of understanding speech. Sound absorption will also help reduce overall noise levels. rr1(% GREENBI.ISCH G rap l) 6T0/%00 fj 919 NE Tist Street Seattle.

An ttolarea of augment sound absorption, in the form of wall panels roof deck absorption. Furthermore, in large spaces such as this, the potential for flutter echo also exists. This is a condition where sound is reflected between parallel surfaces for prolonged periods of time. The "echo" is totally independent of overall reverberation time and may actually appear worse in spaces that are not overly "live". In order to minimize the potential for flutter echo, absorptive treatment must be added along two adjacent lower wall surfaces between 4 inches to 6 inches from the floor and door height. Flutter echo is only apparent at ear height so the treatment must be low. Placing an equivalent amount of treatment high on the wall will have no affect on the flutter echo condition. Wall absorption may any of the following: • Cementitious fiber panels (Tectum or equivalent, with glass fiber batt or board behind) or • Metro Rebound panels by Wall Technology • 4" or 6" Soundblox Type R Conference Rooms and Offices In conference rooms and offices, lay -in acoustical panel ceilings and floor carpeting provide sufficient sound absorption for controlling reverberation and maintaining speech intelligibility.

It also is directly related to the amount of background sound present in the room receiving the intruding sound. People in rooms with higher background sound levels, typically produced by the HVAC system, are Tess able to hear intruding sounds. Conversely, people in rooms that are quieter can hear . intruding sounds more easily. Determination of appropriate wall and floor/ceiling types requires an assumption regarding expected background HVAC levels in the receiving room. Recommended Wal!

Ed. Classroom. For better acoustical performance, we recommend that two doors be installed in double stud wall (one door can be opened into Physical Therapy and the second one into Spec. Ed. Clr.) Noise Control between Gym and Multi -Purpose Room A masonry wall (grouted) currently designed to separate the multi-purpose room from the Gym, will provide an adequate sound isolation between these two rooms for simultaneous use the Gym and Multi -Purpose room assuming that no amplified sound system is used in either room. However, the door will compromise the acoustical performance of the partition. The required acoustical performance of the door depends on expected performance of the composite partition (wall and door). If the Gym is used with sound reinforcement system concurrently with performance in the Multi-purpose room or visa versus, the door selected should be acoustical door of a minimum STC 52. The intruding sound levels with the described construction are expected to be in the range between 35 dBA and 45 dBA, depending on the sound levels in the source room. The predictions assume that source sound levels range from 85 dBA (adequate to amplified speech) to 95 dBA (amplified music) in the source room. These intruding levels will be slightly audible and may be clearly audible occasionally depending on background sound levels in the receiving room. If the better sound isolation is desired, the wall should be equal to Type 5 as described in Table 1 above. Music Room Floor/Ceiling Construction: In order to achieve adequate sound isolation between the Music room and classroom above, we recommend the following construction: • Suspend two layers of 5/8" gypsum board in the Music room on wires with isolation hangers Kinetics ICC or Mason W30. • A 1/4" gap should be left at joint of the GWB ceiling and walls; fill the gap with a low-density fiberglass and caulk with an acoustical sealant. • Fill the joist cavities (about 3/4) with fiberglass batts. • Light fixtures should be surface mounted. • If suspended light fixtures are desired in the music room they should be suspended from the GWB ceiling. • Provide flexible conduit with non-stressed loop for light fixtures. Rigid attachment to the structure above should be prior to non-stressed loop. • Provide flexible connector between the supply diffusers and the sheet metal ductwork. • Acoustical tile should be applied to GWB or suspended beneath. rjl I 1 c GREENBUSCH (31-uti p 919 NE 71st Street Seattle.

Roof Construction We recommendthat the designed roof construction be improved using one of the following options: 1. Add an additional layer of "Durock" or "Wonder" board (1/2" thick) over the designed roof construction. Low density fiberglass batts should be placed between the trusses. 2. Incorporate GWB ceilings in the classrooms on the second floor. The second option is preferable from an acoustical standpoint. It should be also noted that GWB ceilings will provide better isolation of the classrooms from the attic mechanical platforms. MECHANICAL NOISE CONTROL Acoustical Design Criteria The mechanical system design should be in conformance with state public school standards, following the requirements of WAC 246-366-110. Instructional spaces (classrooms) are required to conform to the following maximum permissible noise levels: (1) Design noise levels for classrooms should not exceed noise criteria of NC 35 for ventilation and other mechanical equipment (2) Measured noise levels for ventilation systems at any student location cannot exceed 45 dBA. We recommend including the following criteria for mechanical equipment noise with the project manual: Space NC dBA General Circulation Areas 45 50 Gym 40 45 Classrooms, General Offices 35 40 Conference Rooms, Private Offices, Multi -Purpose 30 35 Music Room 25 30 NC criteria shall be defined and measured in conformance with the requirements of the ASHRAE 1987 HVAC and Systems Guidebook and the National Environmental Balancing Bureau.

Use at least 25 feet of internally lined ductwork (with 1 "thick acoustical liner) downstream (supply air) of the heat pumps serving the rooms with noise criteria NC 30 to NC 35. All return ductwork should be internally Tined. Suspend ductwork on combination spring and neoprene hangers with 1 -inch static deflection for 20 feet upstream and downstream from a connection to a fan or other rotating device. Neoprene hangers should be satisfactory further downstream from the air handling units. Do not allow the ducts to be in direct contact with chase walls or rigidly attached to structural elements. All flex connections should be insulated. Grilles, Registers, Diffusers Grilles, registers and diffusers should be selected 8 NC points below the room noise criterion to allow for generous room absorption effects usually applied to catalogue ratings. Plumbing Use cast iron DW&V piping throughout. Water passing through rain water leaders may be audible in spaces directly below. Rain water leaders over spaces with NC 35 or less need to be wrapped in insulation and surrounded by Kinetics Type KNM-100AL Noise Barrier Material. Use copper domestic water piping. Provide gas charged type shock arrestors at the termination of risers serving flush and solenoid valves, Zurn, Wade, Josam, or approved equal. Piping within 25 feet of pumps should be suspended on combination spring and neoprene hangers with 1 inch static deflection, Mason DNHS or approved equal.

As you know, the applicant filed their SEPA application on October 13. The time for indicating if their application is complete or incomplete is due to the applicant by November 10. This requires me to have all of your comments pertaining only to the completeness of their application due to me by November 3, 1998. The substantive review of their project should begin following determination of completeness. We are tentatively scheduled for a Public Hearing on January 28, 1999. It has been called to my attention that a meeting was scheduled with the applicant for today at 3:30 to discuss "Planning Policy and technical discussion of inter -linked storm drainage issues". Needless to say the outcome of the storm drainage plan and its effect on the Site Plan will have a substantial impact on this development. I was not informed about this meeting and, unfortunately, I or Gary Schulz cannot attend due to prior commitments. When I met with these applicants prior to the submission of their SEPA checklist, I informed them that coordination would be a key to ensuring a successful review. Accordingly, I indicated that if any meetings were held either prior or subsequent to their determination of completeness that I must be made aware of the meetings and the discussion topics. I specifically informed them that if substantial changes were made to their plans after completeness had been issued without my knowledge, it will take them off their schedule hearing date. Memorandum October 29, 1998 Re: Tukwila / Thorndyke Schools Page Two • • Due to the location of these schools in existing residential neighborhoods and their limited site areas, the public review component will be critical. As part of the public review prior to the hearing, a Public Meeting will be held to allow the public to provide comment on all aspects of their plan. Any revisions without coordination will risk the viability of their proposal and will result in a poor impression to the applicant and the public. After their applications have been determined to be complete, I intend to have a twice -monthly meeting scheduled prior to their hearings before the Planning Commission. Due to the scale of these projects, I believe that this will help ensure a coordinated review effort and avoid an ad hoc approach in working with this applicant. I have not yet received the Conditional Use Permit or Design Review applications from this applicant, but expect them any day now. Once these have been received, I will route them as soon as possible to give you ample time for consideration within the 28 day completeness review period. I look forward to working with all of you. epartment of Community Development', rt^ :6300; Soutl center Boulevard; ;Tukw la;- W`y��A7!�'9)818� 1�..r! is'S. 414•''Pi.J t'-1 tr1 .1 t y. �Y. tR . ✓F \ :Telephone .

COMPLETING THE CHECKLIST The checklist contains several pages of questions which you are asked to answer. It covers a comprehensive set of topics. As a result, several of the questions may not apply to your project. If a particular question does not apply, simply write N/A underneath. HOWEVER, be aware that many questions apply despite appearing not to. Care needs to be taken in reading and answering the questions to ensure the appropriate response is provided. It is important that accurate and clear information be provided. You may not know all of the answers. Answer each question to the best of your ability. If we find an answer to be insufficient, the City may contact you to ask for more information. Sometimes, after reviewing the checklist, the City will ask you provide additional studies or information. Commonly requested information includes traffic analysis, site topography, soils studies and tree surveys. _•-- ENVIRONMENTALCHECKLIST Purpose of Checklist: The State Environmental Policy Act (SEPA), chapter 43.21C RCW, requires all governmental agencies to consider the environmental impacts of a proposal before making decisions. An environmental impact statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. Instruction for Applicants: This environmental checklist .asks you to describe some basic information about your proposal. The City uses this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best description you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems, the City staff can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attached any additional information that will help describe your proposal or its environmental effects. The City may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Use of checklist for nonproject proposals: Nonproject proposals refer to actions which are different or broader than a single site specific development project, such as plans, policies and programs. Complete this checklist for nonproject proposals, even though questions may be answered "does not apply". In addition, complete the supplemental sheet for nonproject actions (part D). For nonproject actions, the references in the checklist to the words "project", "applicant", and "property or site" should read as "proposal", "proposer", and "affected geographic area", respectively. CITY OF TUKWILA . 6300 Southcenter Boulevard, Tukwila; Telephone: (206) DEPARTMENT OF COMMUNITY DEVELOPMENT ADDRESS LABEL REQUIREMENTS The City of Tukwila requires that neighboring residents, businesses and property owners be notified of certain types of pending applications in order to encourage citizen participation in the land use process. Applicants are therefore required to submit the following materials: • Mailing labels listing the owners of record for all property within 500 feet of the boundaries (not the center) of the applicant's site (2 sets or 3 sets if SEPA review is required). • Mailing labels listing the residents or businesses of any property within 500 feet of the property if they are different from the land owners (2 sets or 3 sets if SEPA review is, required). • One copy of an assessor's map(s) showing the boundaries of the subject property and the 500 foot radius. Property owner names and addresses can be obtained from the King County Department of Assessment located on the 7th floor of the King County Administration Building, Room 700, 500 Fourth Avenue, Seattle. To compile the information required: • Obtain the assessor's map(s) which contain(s) your property and all neighboring properties within 500 feet (See example diagram). You may use the maps on file in the Assessor's Office or purchase a set from the King County Department of Public Works Map Counter on the 9th floor of the Administration Building. Purchased maps must be ordered several hours in advance of the time you would like to pick them up. • After securing the assessor's maps, obtain a "Real Estate Inquiry Batch Request Sheet" from the Department of Assessment. On this form provide the tax account number for each affected property as shown on the assessor's map(s) and submit the completed form to the Department of Assessment with the appropriate fee. Applicants can request that the information be printed in mailing label form or on standard paper. To obtain occupants/resident/business names and addresses, consult the Kroll maps located in the Tukwila Department of Community Development and then visit the site to determine resident names and unit numbers. The information on the mailing labels may refer to "Resident" or "Tenant", with the proper mailing address, if the specific name is unknown. • �a� - 7/5 - N se) -3 • LEGAL DESCRIPTION KING COUNTY TAX ID: 220150-0320 DESCRIPTION: LOTS I, 2, 3, 4, AND 5 BLOCK 4 EASTLAKE ADDITION PER PLAT RECORDED IN VOLUME 3 OF PLATS, PAGE 11, IN KING COUNTY, WASHINGTON • EgH 1 X71 1.

Rants, Mayor Police Department Ron Waldner, Chief of Police An Accredited Agency Crime Prevention Through Environmental Design (CPTED) Inspection Report Property: Tukwila Elementary School Address: 5939 So 149th St. Date: February 26, 1997 Prepared for: South Central School District (Security Advisory Committee) Prepared by: R. W. Abbott, Tukwila Police Crime Prevention Street Entrance:* The school's street address is not posted. It should be readily visible as one drives up to the property, lighted if possible. Parking: * Parking is woefully inadequate, and does not meet city code (1.5 stalls for each full time employee). There are 38 stalls (including 3 handicap stalls) and 32 full time, every day employees. This does not count occasional employees or volunteers. The parking overflow must park on the street, causing traffic congestion and neighbor friction. _Emergency vehicle response is severely hampered in congested areas. Pedestrian safety suffers as well. Signing: * Property is not posted for "No Trespassing". The signing is required for participation in the Tukwila Criminal Trespass Program. * There is no sign advising visitors to register at the office. * Review signing - there is a profusion of "Weapon Free" signs, many posted in unlikely places, and a lack of other necessary sign types, e.g. "Drug Free Zone". * There is no sign visible in the parking area telling visitors where the office is located. CPTED Page 1 6200 Southcenter Blvd. • Tukwila, WA 98188 • Phone: (206) 433-1808 • Admin. Fax: — (206) 244-6181; Invest Fax — (206) 431-3688 Lighting: *.All exterior lights are wall mounted. This causes the lighted areas to be dappled with bright spots and dark areas. Additionally, these lights tend to blind persons approaching the buildings and make police drive-by patrols difficult and less effective. — The exterior lighting should be accomplished with pole mounted lights (preferably high pressure sodium). These fixtures should shower the areas with an even light. There should be a sufficient quantity of these lights to illuminate the parking areas, and all sides of all the buildings. Landscaping: * Trees and shrubs are remarkably well pruned and maintained, allowing clear vision of doors, windows, play areas and parking lots. Buildings: * The doors appear to have adequate locks that can be secured from the inside. Assure that all adult personnel have access to the "Allen" keys to secure the doors in case . of emergency "lock -down". The Administration building doors use a rubber bungee -type crashbar system that keeps the doors open during business hours, but allows them to be quickly locked in an emergency. This system, while not elegant, appears to work and might be implemented on all the similar doors. * Alarm system: The system should be equipped with a "panic button" feature available to the office staff. Training on the appropriate use of this feature should be given to all personnel who work in the office, and is available through the Police Department Crime Prevention Unit. * Review facility key control. Know who has them, and re - key if necessary. Roof access: * The fences between buildings allow easy roof access for the agile. Consider a roof mounted physical barrier to deter climbers. Planning: * A contingency plan should be drawn which anticipates violence emergencies (e.g. suspicious persons on campus, hostage situations, lock -downs, evacuations, etc.). CPTED Page 2 • • Training: * Staff should be thoroughly trained in the implementation of the contingency plan. Drill: * Both the staff and student body should be drilled on the contingency plan, much as they are on fire or earthquake emergencies.
