Tire Johnson Building, which houses the existing science program, will remain in place and be converted to other classroom and administrative usage. The new building will attach to the Johnson Building, which is at the southern extremity of the cluster of academic buildings. It is important to note that the project does not represent an expansion of the school. There will be no attendant increase in enrollment or staff. Project Team The design team for the Science Building is: Architect Architerra Inc., Boston, MA Civil and MEP engineer Rist-Frost-Shumway Engineering, Laconia, NH Landscape architect Andropogon Associates, Ltd., Philadelphia, PA Structural engineer Souza, True &Partners, Watertown, MA Geotechrucal engineer Haley &Aldrich, Inc., Boston, MA Plans The following plans for the project are submitted: No. Title Prepared bx A0.00 Title Sheet Architerra A2.01 Building Elevations Architerra RFS 06-4984 Narrative 03/15/07 Page I of 7 A2,02 Building Elevations Architerra C0.01 Legends, Notes, and Abbreviations RFS C0.02 Watershed Protection District Plan RFS C1.01 Existing Conditions and Demolition Plan RFS C2.01 Proposed Site Plan RFS C3.01 Erosion and Sedimentation Control Plan RFS C3.02 Erosion and Sedimentation Control Details RFS C4.01 Civil Details RFS E0.01 Photometrics Plan RFS L1.00 Materials Plan Andropogon L2.00 Grading Plan Andropogon L3.01 Landscape Details Andropogon L3.02 Landscape Details Andropogon L4.00 Planting Plan Andropogon Building The new science building is a 30,000 square foot building comprised of two levels and an unoccupied mechanical penthouse. The lower level accommodates five science teaching laboratories, associated lab support and lab prep space, and a student project lab. The upper level accommodates three science teaching laboratories, associated lab support and lab prep space, and a 115-seat large seminar room. A two-level science display space links both levels by means of an interconnecting open stair. The project includes a small free-standing greenhouse located between the new and existing buildings. The project has been designed in compliance with the Massachusetts State Building Code. The lower finish floor level of 172'-6" matches that of the neighboring buildings, while the upper finish floor pf 186'-6" is two feet higher than the existing Johnson Building to which it connects via a ramp. See attached Zoning Code Summary regarding building height. Based on this analysis, it is concluded that a variance under the Town Zoning Bylaw is not required. The new building is supported by a conventional steel frame and features red brick, precast concrete, aluminum windows and curtainwall, and a standing-seam metal roof. The roof stricture is exposed glue-lam wood beams and trusses with wood decking and heavy timber cave brackets. The building foundation will be conventional cast-in-place reinforced concrete with spread footings. Underslab drains will be installed along with perimeter footing drains in areas where the finished grade is higher than the first floor level. RFS 06-4984 Narrative 03/1 5/07 Page 2 of 7 The building is designed to harmonize with the existing campus architecture and natural setting while exemplifying energy-efficient, environmeiitally-resporrsible design. Greer features include a partial green (vegetated) roof, wet-dry garden, solar cupola, entlialpy heat recovery, energy-efficient lighting, solar shading, and a demonstration photovoltaic array. The greenhouse will be a one-story, gable-roofed structure, with vented double glazing supported on a quality wood or metal manufactured frame. The overall footprint is proposed to be approximately 12' x 20'. The base of the greenhouse will be stone or concrete to harmonize with the garden design. The greenhouse will be used to support science instruction, energy demonstration, and independent student projects, and is the focal point of the wet-dry garden, itself an educational tool. A precast concrete underground cistern will be placed beneath the floor of the greenhouse to store runoff from a portion of the roof of Kingsbury Building. This water will serve as irrigation supply for the greenhouse via a small student-operated hand pump. Site The new Science Building will be placed at the south extremity of the campus cluster of academic buildings on either side of Main Road. It will attach to the south wall of the Joluison Building, and will occupy what is now a grassy knoll between that structure and the existing access drive. This drive leads to four existing faculty housing units and the gravel access to the School's boat house on Lake Cochichewick. Luce Library, the main School library, lies just to the east across Main Road. Luce also houses the School's business office. The main entry of the Science Building will adjoin the principal campus pedestrian way. The main floor elevation (elev. 172.50) will match the floor elevation of Jolurson Building. A courtyard will be created between the new building and the Kingsbury Building which is attached to the Jolmson Building. The courtyard will feature pedestrian pathways and seating areas with the central element being a wet/dry garden irrigated primarily by roof runoff(see Stornwater section below). See Landscape plans. The site is located within the watershed of Lake Cochichewick, the source of the Town's water supply. It thus lies within the Watershed Protection District (WPD). Most of the project site is in the General Zone of the WPD. The proposed detention pond and drain lines associated with the pond are located within the Nori-Discharge Zone of the WPD. A Watershed Special Permit is therefore required from the Planning Board, along with Site Plan Review. See Watershed Protection District Plan for delineation of zones on the School campus. RFS 06-4984 Narrative 03/15/07 Page 3 of 7 Trees The Brooks School campus is noted for its natural beauty, including many fine tree specimens. The site for the Science Building project contains a number of existing trees. To assist the project team, the site was examined by a certified arborist for the purpose of determining relative value and condition of trees, which was of considerable assistance in siting the project and deciding which trees to preserve. Attached hereto is the arborist's letter report. Of particular note is the very large red oak south of the new main building entry which will be protected and preserved. Stornlwater The bulk of new developed area consists of the roof of the building and the creation of the interior courtyard. The remainder is the new front entry and small parking area. The interior courtyard will feature a wet/dry garden with multi-tiered small impoundments intended to hold shallow pools of water for a limited time after each rain event. Plantings are selected which are compatible with this environment. In significant storms, the impoundment levels will rise to spill over small stone weirs into the next downstream pool. Flow to each tier will be augmented by leaders from downspouts from new and existing roof areas. The lowest pool will spill into a riser structure which flows into pipes directed through a "Downstream Defender" storinwater treatment unit and then to an on-grade detention pond with sediment forebay. Discharge from the detention pond flows onto a stone apron and then slieet flows downhill to the lake, about 300 feet distant. Because some of the developed area of the project lies within 400 feet of Lake Cochichewick, a public water supply reservoir, Mass. Storinwater standard 6 regarding "critical areas" applies. This standard calls for a treatment volume based on 1-inch of runoff rather than the %-inch standard for non-critical areas. The treatment train for this project exceeds this standard, and is in fact capable of meeting the TSS removals even in the 100-year storm, a 6.3-inch event. A majority of the new roof nlnoff will be directed to an underground infiltration gallery to meet the groundwater recharge standard. Test pits and percolation tests conducted by Norse Environmental were relied upon for the sizing of the gallery and the exfiltration rate in the calculations. hi large storms, overflow frorn the gallery is directed to the detention pond. The new entry area actually has slightly less impermeable area than at present. The existing catch basin at the small new parking lot will be fitted with a baffle hood to trap oils and grease. See Drainage Calculations for summary of the attenuation of peak rate of runoff to rneet the standard of no net increase in peak flow rate. RFS 06-4984 Narrative 03/15/07 Page 4 of 7 Utilities The campus water supply consists of a network of mains connected to the Town system. Flow tests conducted in 2001 indicate that a simple 6-inch connection to the main in the nearby access drive is sufficient to feed the fire suppression sprinkler system for the Science Building without the need for a fare bump. Later in the spring, a new flow test will be performed as required to verify the above conclusion. Sanitary sewers on campus flow to a central purnp station located in the center of campus near Danforth Gym. The buildings oil the lake side of the north-south ridge line flow to gravity sewers which discharge to a small pumping station located downhill from the Science Building site. This station discharges via force main to the main campus pump station noted above. The Science Building sanitary sewer service will connect to a manhole on the existing gravity sewer in the adjacent access drive. Given that the teaching of science involves experimentation with chemicals, an exterior acid neutralization tank will be employed to buffer the pH of wastewater from the laboratories. It is understood that chemicals and reagents are delivered, stored, and used in small lots. Chemical storage is provided for in lab prep rooms, separate from teaching spaces. The School maintains a network of natural gas lines which is supplied by Bay State Gas. A central metering and pressure reducing station is located in the rear of the Dining Hall from which the campus gas network emanates. The Science Building will be connected to the campus gas network for heating purposes. The School maintains an electric power infrastructure network, primarily in underground conduits and vaults. Power is supplied by Massachusetts Electric. Underground primary power will extend via a concrete encased duct bank from an existing underground vault on the south side of the access drive to a new pad-mounted transformer adjacent to the new building. Underground secondary voltage power will extend from the transformer into the buildling's mechanical room. In a similar manner, the new building will be connected to the School's telecommunications systems for telephone, CATV, and data functions. Access and Parking The site takes advantage of the existing access drive which primarily serves a cluster of faculty housing units and the campus boathouse. It is proposed to leave this drive in its existing alignment and condition. It is likely that the drive will be resurfaced or rebuilt under a separate budget in the not too distant future. Three existing parking spaces will be removed to make room for the new main entry. Two spaces remain, including one handicapped space. RFS 06-4984 Narrative 03/15/07 Page 5 of 7 Five new parking spaces are proposed in the rear of the site, near the terminus of the existing access drive. There will thus be a net increase of two spaces, even though there will be no increase in staff or students. Included in the background information for this application is a copy of a campus-wide parking study prepared by RFS in 1999. The purpose of the study was to inform the Town at that time regarding the parking situation on campus prior to a planned series of capital projects. A boarding school with significant resident faculty is far different than public schools or private developments as far as parking requirements are concerned, and strict adherence to square footage tables and the like would result in excessive parking. The Planning Department accepted the report at the time for its intended purpose. While somewhat dated now, the principal conclusions remain true, namely 1) there is ample parking available on campus, 2) no one need ever seek parking along a public way or in such a way as to impede emergency access, and 3) paving over attractive green space to meet rigid square footage requirements serves no good purpose. Site Li hg ting The developed area is small and devoid of expanses requiring significant levels of additional lighting. The courtyard and front entry will be lighted via small step lighting fixtures. See photometric plan. Waiver of Boundary Survey The project site is well within the School's 165-acre property. The nearest part of the project to adjacent property is over 450 feet distant. Performing a complete boundary survey of the large campus would be an unnecessary burden. It is requested that the requirement for a boundary survey be waived. Waiver of Traffic Study There will be no increase in staff or students as a result of this project, therefore there will be no increase in traffic. It is requested that the requirement for a traffic study be waived. Fiscal Impact Demand for added public services will be negligible. The campus is already connected to the Town water and sewer systems. No off-campus upgrading or new construction of the public facilities is required. The project will have no impact on tax revenues, as the School is exempt from property taxes. RF8 06-4984 Narrative 03/15/07 Page 6 of 7 The Science Building will be a high quality facility which will enhance the appearance of the campus. Any effect on adjacent property values would be expected to be positive. Community Impact The Science Building is entirely consistent with the long-established campus and surrounding aieighborhood.

N' t ; = No pesticides, herbicides or fertilizers are to be used within the 100' buffer zone of any Wetlands. Note 4 = Other applications will be made as required and in reference to the applicabilty of Notes 2 and 3 Note 5= Soil tests/sampling will be conducted annually in the month of October in all four areas Supporting Supporfing Information Note 1 : Is Standard Written Notification required if a school is on vacation? Usually school vacations or school breaks are times when classes or activities are not taking place for 5 days or more and would therefore be an acceptable time to make pesticide applications if warranted. If pesticides are going to be used on school property during a time like a summer vacation or a winter break,and classes will not be scheduled,Standard Written Notification does not need to be sent out.However,posting is still required both along the perimeter of the area to be treated and at a central location. Note 2 :Are private athletic organizations (e.g.youth soccer, little league),whose memberships are exclusively school children , considered within the requirements for notification purposes? Under the law,only groups that are school managed or school sponsored are required to receive Standard Written Notification. Therefore,because these groups are not school sponsored,it is not required that they receive the Standard Written Notification even though they may be on school property.Sign posting should provide enough protection for these particular groups. Note 3 : How many pesticide flags are needed around the perimeter of a treated field? There is no set number of pesticide flags that will need to be placed around the perimeter of a treated field. The flags to use are the small yellow lawn care flags required by Massachusetts lawn care regulations.Such flags can be purchased from Gemplers at www.gemplers.com or by calling 1-800-382-8473, However, the Department is recommending that an applicator post signs conspicuously around the field so that someone entering the field from any direction would be notified that a pesticide application had taken place, Note 4:Are fertilizers covered under the law? Fertilizers containing only nitrogen,potassium,and phosphorus are not defined as pesticides and are not covered under the children's protection law.However, those fertilizer products that contain insecticides and herbicides(commonly known as weed and feed products)are in fact pesticides and are governed by this law. How do the North Andover ZoningBylaws pertain to the use of garden products'? Y P 9 P The Town zoning bylaw prohibits the following in the non-discharge,non-disturbance,and conservation zones: "the use,or method of application of,any lawn care or garden product(fertilizer,pesticide,herbicide)that may contribute to the degradation of the public water supply." See 4.136.3,b.iii(2)(page 60); 4.136.3.c.iii(4) (page 62);and 4.136.3.d.iii(g)(page 63), 2/12/2004 2 Hariney Greyrnonl,Inc.

There are several trees in close proximity to the proposed construction and I understand the desire that exists to protect the trees in this area. I am pleased that you have contacted me prior to any construction activity. The key to successful tree preservation efforts are prevention and communication. Based on my initial visual ground inspection and evaluation of the trees in question, I present the following for your review. The most serious construction injury involves damage to the fragile root systems. Trees will often appear to survive the initial construction activity only to slowly decline 3 to 6 years after construction has completed. The primary cause of tree decline and death following construction results from damage to the soil within the root zone of trees. Soil compaction, grade changes, as well as direct injury all effect tree roots. There are no guarantees with living organisms, and even with every action taken, no guarantee of survival can be made. It is critical for all individuals involved in project planning and construction to respect the efforts and activities designated to protect trees. Preventing damage is far less costly than efforts to try to correct it. Preservation Candidates (tree canopies indicated on construction site plant) RED OAK This is obviously an impressive specimen, but has serious structural and rooting issues including trunk decay, large codominant leaders, and its proximity to the road and sub-surface storage area. The tree appears to have been recently pruned, I assume to remove deadwood, perhaps within the past 2-5 years. The tree has formed little to no callous tissue around these old pruning wounds, which is a sign of the tree's advanced age and reduced vitality. The tree has outgrown the existing supplemental support cables. To prevent future structure failure and reduce potential storm damage, additional pruning and cabling is recommended LITTLE LEAF LINDEN This is a mature double-trunked tree. At the union of the two trunks recent woodpecker damage has occurred and indicated the presence of decay and insect activity. The size of the tree and proximity to the road present additional potential hazard issues. The tree appears to have some sizable deadwood throughout the canopy. Pruning and supplemental cabling would be prudent to help prevent future safety issues. Continued on next page ... November 14,2006 Ellen Watts Architerra, Inc. 68 Long Wharf Boston, MA 02110 RE* Brooks School, North Andover Page 2 AMERICAN BEECH This tree is a fairly young tree and appears to be in good health. The species in general is not tolerant of disturbance. WHITE OAK This tree is a fairly young tree and appears to be in good health. HAWTHORNE This is a small multi-stemmed flowering ornamental. This particular hawthorne, along with the black locust, and large Norway maple growing near each other may not be as desirable as the trees along the edge of Boat House Road. Due to the species and current condition of the trees, preservation efforts may outweigh the benefits of protecting these three trees BLACK LOCUST Refer to hawthorne notes. NORWAY MAPLE This is a mature tree and has some fairly significant root issues. There are encircling and girdling roots present at base of trunk. This is a common flaw associated with this species. Girdling roots can restrict the vascular system flow and can also create a weak point for structural failure during storms. Norway Maples can be a problematic landscape species and are now considered to be an invasive plant. APPLES These two trees have serious structure and health issues. However, due to the advanced age and character of the trees, they are quite unique and therefore may be worthy of preservation. It is nearly impossible to age these trees, but I would suspect they are some of the oldest on the campus. These two mature apples may serve as symbols of the care and effort to preserve the school elder trees. Additional notes: In general the trees within E feet of construction excavation should be removed (none of these trees are noted on the site map and I assume are slated for removal). Small kousa and magnolia (+/-3" diameter)within construction limits could be transplanted elsewhere on the campus. All trees to be preserved between Boat House Road and the limits of construction should be protected (not all trees are identified on the site map). Two red pines adjacent to the mature apple trees may be better suited for removal over preservation. Continued on next page .. November 14, 2006 Ellen Wafts Architerra, Inc. 68 Long Wharf Boston, MA 02110 RE: Brooks School, North Andover Page 3 POTENTIAL PRESERVATION ACTIVITIES Install steel fencing and preservation signage to delineate and protect critical root zones. • Gather and prepare soil sample analysis within critical root zones to determine soil pH and base saturation levels. • Require communication and cooperation among all participants involved in the construction and tree preservation process • Structurally prune and cable if necessary all trees to be protected prior to construction. • Fertilization to replenish soil nutrients and increase stored energy with trees, promote vitality and natural defenses. • Cover protected root zones with composted wood chips to condition and protect soil. • Root prune prior to construction excavation to prevent mechanical injury to roots and to encourage proper wound compartmentalization and regeneration. • Above ground, supplemenental irrigation within protected area during warm weather periods to prevent water stress Please contact me with any questions or further discussion.
