March 31, 2006 CAMPUS FLOODING BUILDING DESCRIPTION STATUS Architecture The School of Architecture sustained leaks in the following areas due to the downpour in late March. There were leaks in Architecture 310 and the second floor ramp entrance. Bilger and Bilger On Friday, the courtyard accumulated water in front of the Natural Sciences office to within one inch of entering the lower set of rectangular vents and starting to flood the old Addition Bilger basement again. This is a dirt floor basement under the office of the Dean of Natural Sciences and the lecture halls. There are a number of these vents at different levels, I just happened to notice that we came within one inch of starting to fill the "dungeon" again. During the famous flood, water accumulated in there to a depth of six feet+ and we were saved by a strong wall that kept water out of the Bilger Annex Basement. In the Bilger Annex Basement is a major transformer vault. If that had flooded we would have lost power to all of Bilger and Bilger addition at least. We would have lost power to all of telecom and the campus police repeaters and all of our telephone system would have ceased working for heaven knows how long and the flooding of a major power vault would have been "dramatic" to say the least. Without such power distribution, the phones would have not come back online and the campus police repeater would not have started working again for weeks aafter the flood or at least until a big generator could be installed and cables run. It was a bit scary to see the water line clearly marked just above my head on the dungeon side of that wall, which is fortunately load bearing and very strong, serving as a dam. Of course, we would have needed an hour or so of water cascading into those vents to reach a depth like that on Friday and God cut us some slack at the last minute. For some reason the metal grate in front of the addition, on the Correa Road side was banging very fast like a chattering relay. Never figured out why but during the height of the rain, it was very noisy for an hour or so, perhaps inadequate flow? Not clear what was up with this. This is the one near the new sidewalk partially covered by the new plantings. Water was not upwelling out of it but it was rattling like crazy. Bilger and Bilger With respect to Chuck Hayes' recent email concerning flooding and leaking within buildings, we should draw their attention to two major areas: Bil 335 has a pie-shaped piece Addition cornored off because the ceiling tiles were coming down during the recent downpours. You can look up and see the rebar and some light fixtures seem to have been water- logged as well and are in the process of coming off. As long as you are not getting hit in the head by falling concrete, it is mostly unsightly and an embarrassment. More importantly, some attention should be given to the exhaust vents on the roof of Bilger Addition. As you know, whenever it rains heavily, rain falls into the vents and exits in places where the vertical pipes make the turn on various floors and are directed towards the hoods. Water leaking from these pipes inevitably soaks the ceiling tiles and makes them crash down. As a result, the hallways in Bilger Addition look as unsightly as they do. More importantly, as a result of water leaking out of the exhaust vents onto the floor in the hallways Bilger Addition 4th floor, the Tius lab gets flooded at least once or twice a year. Since the lab does not have floor drains, the water leaks from there into my lab below. This has led to equipment loss in the past and is a serious safety hazard when shorts occur in electrical apparatus, as has happened in the past. Last, the roof that was installed a few years ago shows some serious holes in them area above the Chem office wing (Bilger Hall). While there were no apparent leaks during the downpour, maybe Bilger and Bilger The parking lot between Bilger and PSB, near the moutain end, often has sitting water and/or floods in even moderate rain. I'm guessing you (Chuck Hayes) are well aware of Addition it, from parking near there, and the recurrent threat to the Bilger and the first floor of Keller. Making sure the obvious gets metnioned (grin). BioMed Building Large drain pipe that opens just above Biomed building seems the source of water that flowed to the building in October 2004. Manoa stream level, when breached, causes pooling. Would like input of qualified hydrogeologist to investigate. Crawford Hall In response to your inquiry about flooding and leaks, last week rains revealed leaks in the ceilings in third floor hallway of Crawford Hall as well as the ceilings in Crawford 302 and 320. We have sent a report to Facilities. CAMPUS FLOODING BUILDING DESCRIPTION STATUS Edmondson Hall Here's a list of problems with Edmondson Hall: (1) when sewer drain by loading dock between Snyder and Edmondson gets clogged, it would be nearly impossible to stop the first floors of both buildings from getting flooded; (2) the concrete driveway that goes from Maile Way down the Donogho Road side of the library and to the back of Edmondson as well as the loading dock goes downhill. If storm drain is clogged see #1. If there is enough water, it would get very neatly channeled right through the first floor hallway of Edmondson -- it's almost as though someone was building an artificial stream through our building. Finally, our boat cage gets ankle deep in water and the water could very easily flow through the door of our storage room into the first floor; and (3) some roof leaks but the above are our biggest risks. Gartley Hall Gartley Hall's basement flooded on 3/31/06. Water percolated from beneath the foundation which indicates some serious structural problem. Gartley Hall Gartley Hall flooded, water shoots out of basement floor tiles and wall during heavy rain, associated with floor subsidance. Facilities showed up quickly with more efficient water removal system. Flooded and unusable -- several offices, seminar room, research offices, 2 bathrooms, office for undergraduate advising. George Hall We have a perennial problem with George Hall's roof leaking. Last week, I had a ceiling panel cave in and water soaked through my carpet. Fortunately, my computer was spared. Several offices in my department, and in the hallway, have leaks either due to blocked ducts on the roof OR air conditioning problems. This has gone on for at least 15 years. Workers simply come to put up new ceiling tiles and never get to the problem. George Hall George Hall -- 101, left corner near window and near entrance door, ceiling leaks (probably from upstairs lanai); 101, corridor, ceiling leaks; 112, 113 corridor, ceiling leaks; 201 (Sunset Reference Center), ceiling in multiple areas, ceiling leaks, water damage to carpet, humidity causing mold and mildew on library books, shelving, windows, etc.; 202, corridor between grad room and faculty offices, ceiling leaks, damage to walls; 211, corridor, ceiling damage, moisture problem on corridor wall; 226, ceiling damage; 346, multiple areas, ceiling leaks; 345, ceiling leaks. Hamilton Library I am the Hamilton Library Building coordinator. Diane Perushek and Bob Schwarzwalder (Asst Univ Lib) are on the mainland for part of this week so I will send you a list of our flood/leak areas of concern. Diane and Bob may want to supplement this when they return. I can only speak to the problems with Hamilton Library. Sinclair Library also has many water-related problems, mostly having to do with many roof and wall leak sources. Since it is built on a rise, it is not as vulnerable to the sort of massive flooding that Hamilton has experienced. Hamilton Library has always had a problem with water, and I suppose we are more sensitive to it because of our collections. Even small roof leaks can destroy or heavily damage books. A major flood, of course, destroys everything. I apologize for the lengthy message, but we have numerous water-related problems. POTENTIAL FLOOD RISK: (1) the ground floor areas of the library are at the highest risk of massive flooding. Since the older portion of Hamilton is situated in the bottom of a drainage basin, the building acts as a dam for flood waters coming down from Manoa. Last Friday's rain (in my opinion) came very close to recreating the 10/30/04 flood. Manoa Steam overflowed its banks at the same bridge near Manoa market place and water was heading down Woodlawn Drive towards Noelani School. The intense rainfall abated before flooding got any worse. The drainage ditch that borders Mid-Pac also overflowed its banks at this time; (2) the ground floor of the Phase III addition to the library received only minor leakage during the 10/30 flood. It would have probably flooded as well if the water had been a few inches higher. If this basement were to flood, the water would have nowhere to drain and approximately 7-8 feet of water would have to be pumped out; (3) the 1st floor of Hamilton Library was partially flooded during the 10/30 flood. The water came in through the doors and window frames and damaged flooring and walls. If the water had been a few inches higher, we would have had two floors to reconstruct instead of one; (4) another potential cause of flooding is a blockage in the main box drain that is buried between Hamilton and Edmondson Hall. In the 1960s (I have been told) this caused a flood of about a foot in depth in the ground floor of Hamilton. CAMPUS FLOODING BUILDING DESCRIPTION STATUS ROOF LEAKS: (1) Hamilton Library is subject to numerous roof leaks, despite the fact that two-thirds of the building is covered with roofs that are no more than 5 ot 6 years old. The oldest portion of the library (which we call Phase I) has roof fabric that is thin enough to see through in places and numerous leaks have come through this roof during the last rainy period. Facilities tells us that a roof replacement is in the works; (2) the three-year old roof that covers Phase II of the library has had on-going leaks since it was first installed. As a result, large portions of the 5th floor, which houses the Hawaiian-Pacific Collection, are covered in plastic and are equipped with buckets; (3) the roof over the Phase III addition (about six years old) leaks whenever the sealant fails in one of the numerous electrical junction boxes whose conduits penetrate the roof. Directly underneath this roof are the collections of University archives. Thus far, leaks in this roof have been fairly minor, but unpredictable. WALL, WINDOW AND OTHER LEAKS: (1) the sealant is failing around some of the window frames in the library. When rain is wind-driven, water comes through into the building; (2) there are cracks in the walls of the Phase III addition. Some of these seem to be getting worse and are showing evidence of water penetration; (3) some of the downspouts in the Phase III addition seem to be plugged up. Even when the weather is dry, there is constant dripping (probably condensate water) coming from the overflow scuppers of this building; (4) when air conditioning fails, this will sometimes result in condensed water falling from the non-insulated ceiling air ducts. These are similar in nature to roof leaks. Our drop ceilings are spotted with water spots resulting from this. Hamilton and I would like to add two areas: 1) The "old reading room" on the first floor of Sinclair library leaks both from the roof and jalousie windows. There is frequently enough rain Sinclair Libraries coming in the windows enough to result in water about an inch deep in large sections of the floor. Large plastic sheets are attached to each window to try to conduct the water outside the building. (This is where the well-known Library Fern Wall is.) In addition, water on occasion during bad rainstorms has cascaded down the public stairway in Sinclair between the first and second floors. 2) Leaks in Hamilton Library's third floor have occurred unabated for years. We have permanently rigged huge plastic sheeting into funnels from the ceiling into large garbage containers in part of the stacks; and the surrounding bookshelves are covered with plastic sheeting. The water, during some storms, rushes down the chutes into the garbage containers, and is measurable in gallons per hour, or gallons per afternoon. Finally, the main workroom in our Special Collection Department in Hamilton has been totally draped in plastic sheeting for years now. Staff remove the sheeting from a desk and computer table to work, then put it back when they have duties elsewhere or when they leave for lunch or for the day. Hamilton and 1) Flood Prevention/Mitigation at Hamilton Library. Hamilton Library is at significant risk of future catastrophic flooding. We endorse the draft plans by Kimura, Ybl & Associates Sinclair Libraries to create a flood barrier wall on the side of Hamilton Library facing Maile Way and a by-pass conduit through the Hamilton Library loading dock to prevent losses on a scale to those suffered in October 2004. This work should be covered by the "ground floor renovation project," UHM 04-541-801. 2) Replacing Sinclair Library's Roof: There are two major areas of leakage in Sinclair library. They are the third floor roof and the roof of two-story mauka wing where the Mezzanine is locted. These areas have had numerous leaks over many years. In the Wong Audiovisual Center, for example, the leaks were so bad that parts of the ceiling have fallen down. The Sinclair Library roof has been patched numerous times, most recently in 2006; however, contractors have cautioned the Library that the concrete in the roof is decomposing due to recurrent water damage. An inspection by Facilities in 2005 resulted in a recommendation to replace the roof as soon as possible. There is no replacement scheduled at this time. 3) Replacement of the hamilton Library Phase I Roof. This roof has numerous leaks. While it was patched this year, the roofing material is extremely thin and badly in need of replacement. We understand that Facilities plans on replacing this roof; we do not know the priority of this project. CAMPUS FLOODING BUILDING DESCRIPTION STATUS 4) Repairing Phase II Roof Leaks. The roof on Phase II of Hamilton Library is in good shape, but has several areas of ongoing leaks. We believe that these may be related to structures on the roof that have been improperly sealed. As this roof is above our Hawaiian-Pacific collections, some of the rarest and most culturally relevant of our holdings, these problems are a real concern. A solution to this problem is not as clear as in other areas of concern and may require some investigation. 5) Establishing a Regular Maintenance Routine for Hamilton and Sinclair Libraries. Even on newer roofs, such as the one in Phase III, we experience leaks when the sealant on electrical junction boxes fail, or tears appears in the roofing fabric. As our building ages, the seals along the windows are beginning to fail. This allows wind-blown rain the enter the building. Cracks have appeared in the walls of Phase III, some of which are allowing water to penetrate the structure. The aging AC system results in leaks from air- handlers and condensation alike. Our ceilings are stained from such leaks in locations cattered throughout Phases I and II. Downspouts and drains around the xterior of the building have gotten partially to mostly occluded, allowing rain and flood water to back up and pre venting proper drainage. A regular maintenance program would prolong the life of our facility, prevent collection losses, and save the university money. Hawaii Hall Also, there is a leak in a window in Hawaii Hall 310F. Henke Hall The first wing of Henke Hall has a leak in the roof that has caused a large pool of water (about 5'x2") in a high traffic area. HIG Holmes Hall Water leaks reported by the Electrical Engineering Department which is located on the fourth floor (top floor) of Holmes Hall. The basic problem is that, although the roof was reroofed several years ago, it continued to leak even afer the reroofing. We have contacted Facilities on numerous occasions whenever we have a hard rain and they have been able, in some cases, to provide temporary solutions for the leaks. Laboratories, faculty offices and our computer facilities haave been adversely affected by these leaks: Room 410, left side of door; Room 436, right side of room; Room 439, water comes in from window; Room 440, right side of room; Room 441, left side of room; Room 445, left center of room; Room 449, left side of room; Room 451, above 1st lab table; Room 453A, left side of room; Room 458, top right corner (water leak has seeped to 3rd floor damaging ceiling; Room 485, right mauka side of room; Room 486, left and right side of room; Room 487, above water sink and center of room; Room 488, right side of back wall; Room 491A, water dripping from a crack in the ceiling front of door that enters to 486; Hallway, outside of 485. Keller Hall ITS has two major unaddressed issues during flood conditions on the Manoa Campus -- protecting Keller Hall which impacts the entire Manoa campus and UH System and rain impact mitigation for Building 37 which has roof leaks and is vulnerable to flooding. In addition, we hope the campus can maintain a high priority for the current work to address the roof leaks in Bilger Addition. If not controlled, this could negatively impact campuswide phone services. Keller Hall -- Keller Hall is in the "flood plain" just makai of Hamilton Library. The data center is on the ground floor. During the 2004 flood, water and mud entered the data center lobby area and aproached the machine room before it was diverted by on-duty staff. Water again approached the Keller entry on Friday, 3/31/06. Entry into the building was averted because this was daytime and the building custodian manually cleared the drain just mauka of the Mall entrance to the building. For Keller to survive in flood conditions, it is critical that the mall drains be as open as possible to divert water from entering the building. Ideally, there would be improved drainage as well. CAMPUS FLOODING BUILDING DESCRIPTION STATUS Having sandbags available within the building to barricade the lobby entrance would be a very useful interim energency mitigation strragegy that ITS staff could execute. Please advise if sandbags can be provided for Keller. Building 37 -- the roof leaks. Additional leaks have been exposed over the past weeks and with the downpour on Friday, we had a larger number of active simultaneous leaks all over the building. When this happens, we need to turn off the lights to avoid electrical effects, remove ceiling tiles, and mount plastic (provided by FMO) ceiling-to-floor to divert the water into garbage cans. Depending on where the leaks are, individual staff may not be able to work while this is going on. It's pretty easy to see that the shingles are worn and spotty, so given the number of leaks it would seem a complete re-roofing would be most effective and appropriate. If patching is decided on, please let us know how we can best identify the locations of leaks for later patching. The second Building 37 problem is drainage around the building. On March 31, we were close to having water enter the building from two of our three doors. We'd like to get some sandbags to store in the building as an emergency preventive measure. As with Keller, please advise if you can provide. Longer term, there are two things we oticed. A gutter system would be one way to route the water directly from the Keller Hall The 4th a nearby drain. In addition, too numerous grrading and drainage work around the building. On March 31, we a major area of the ceiling of classroom Keller 413 the roof into floor of Keller Hall has leaks we need some to mention. Most are now just ceiling stains, but the worst ones are had standing water up several inches at the base ofand a mold growth on the ceiling (long time leaky area, tiles replaced a few months ago) of the Chair's office in Keller 401A. I recommend immediate attention to the mold. Krauss Hall NICE Program Office -- rug in two rooms became partially wet. Will dry carpets and see whether we can manage without replacing them. Floor of the John Young Museum may buckle as a result of the flood. May have to re-varnish the surface. Drainage structure around Krauss Hall needs to be re-examined and possibly re-designed. For Outreach College, the general drainage system around the mauka and Diamond Head sides of Krauss is a problem. The capacity of the current drainage system is inadequate to handle any heavy rainfall and the area has been flooding the John Young Museum and classrooms. Kuykendall and Flooding issues related to LLL buildings: (1) the elevator for KUY is certainly at risk -- high risk. And once it's hit with water damage it is costly to repair -- and it can be out of Moore use for weeks, as we saw two years ago; (2) Moore Hall was also hit by the flood. I was here the night it happened. All the power went out and the area around Moore was flooded. We could not use Moore for at least one week. Marine Science MSB 500 lab; water dripping from ceiling and puddling on floor. Fortunately, all instruments are gone to the field so little damage this time. Maybe now, while it is dripping, Building would be a good time for them to revisit the problem. Marine Science MSB roof leaking badly. Facilities came over to take a look and advised us to cover up with plastic sheeting. When asked if any facilities people would be around over the Building weekend, as more rain is forecast, they said no, but we could call 6911! Marine Science MSB 629 -- roof leaked, Facilities provided plastic sheets and buckets. Building Marine Science MSB 631 -- 3 leaks in office. Cracks in concrete ceiling. MSB 634 -- 1 leak. Crack in concrete ceiliing. Building Marine Science MSB 520 -- water dripping from ceiling by fume hood. Dripping stopped when rain stopped. Building Marine Science MSB 616 -- leak from roof. Building Marine Science MSB 500 -- leak in lab (same spot as last year). Last year it soaked a sensitive $40,000 instrument. Facilities came and poked around but never did anything. Building CAMPUS FLOODING BUILDING DESCRIPTION STATUS Marine Science Hallway fronting MSB 628/629 -- 2 leaks -- one ceiling tile absorbed so much water that it broke and fell to the floor. Building Marine Science MSB 610, 616, 618, 628, 629, hallway, 631 -- all leaks came from either cracks in the ceiling/roof or from a conduit penetration. Building Marine Science MSB 603 -- steady condensation drip from the a/c system. Building Marine Science As you know, the Institute for Biogenesis Research (IBR) located in the E-Court of the BioMed building, suffered major flood damage on October 30, 2004, from which we have Building, Institute recovered. Last Friday's rain brought flood water to our door, but this time it did not enter. I saw a drawing from facilities that showed the plans for a wall that would prevent for Biogenesis such a flood in the future, and I urge you to consider getting this started. In addition, we continue to have a strong leak in our roof in the center of our labs (room E102). It Research would be nice to get that fixed at some point. This leak came through again on Friday. Miscellaneous I spent a little time Saturday morning looking along Manoa stream, including (but not restricted to) the area near the Woodlawn bridge, and talking to people. The water last Friday rose to nearly the same level as it did during the Halloween flood. Very significantly, the stream appears to have flooded this time with little if any debris clogging the Woodlawn bridge. No one I spoke with mentioned much in the way of debris, and I found no physical evidence of big pieces of debris (like trees) playing a role in the flood last Friday. I think the probability is very high that if the Halloween flood had not occurred that the flooding on campus last Friday would have been worse than what happened during the Halloween flood. The Halloween flood flushed out debris and prompted debris removal -- if that had not happened, a flood of the campus on Friday almost certainly would have occurred, and it very well could have been worse than the Halloween flood. If the impression from last Halloween was that the debris along the stream was the main culprit, I think that conclusion needs to be reviewed. The carrying capacity of the stream, the flow rates that can occur during heavy rainfall, and debris are all factors. Miscellaneous Here's the list of areas that were affected on Friday, 3/31/06. Bus Ad, A101 Auditorium, C Tower; St. John, 4th, 5th and 6th floors; Ag Science, basement; Gartley, basement; Bio Med, Lanai areas, 2nd and 3rd floors; Art Building, 3rd floor pool of water on walkway; Krauss, gallery area; Hawaii Hall, lanai areas. Miscellaneous One of the Senate committees (COR) has drafted a resolution about "what have we done to fix the flood problems for the future". I'm guessing that it would be good public relations to distribute (maybe soon) an update of some kind. I'm sure that engineering studies have been done/are being done, and I'm hoping that the scope of the problem may have been definied. If "we" (the state? the feds?) have reached any tentative conclusions, that might be good to describe. I'm contacting you first, although I am sure that several system-level people are also part of this. Off the top of my head, I can think of some "answers". 1) a dam in Manoa. Impractical. No room; 2) a bigger drain through the campus (the one that goes underground beginning at Maile Way just a few feet from Hamilton Library); 3) there may be a drain that feeds into the campus from somewhere else in the value, at some pooint near the formerly-Jabsom building. Maybe reroute that drain (underground?) to the stream; 4) one can install (very expensive) steel flood barriers that rise up from recesses in the ground and surround buildings during flood emergencies/alerts. I've seen these in Washington DC, protecting some very nice property owners who want to (otherwise) enjoy being on the banks of Potomac (literally, with water gurgling near an outdoor patio); 5) somehow changing the bridge on Woodlawn Drive so that it doesn't reroute the stream at high water. CAMPUS FLOODING BUILDING DESCRIPTION STATUS Regarding the more immediate flood, "we" might report on these technical details: A) in 2006 there was more water than in 2004 (is this true?) but in fact the stream cleaning had prevented a dam forming at the Woodlawn Bridge and thus there was no crisis (again, if true!); B) the local flooding on campus was caused by debris in the Maile Way drain, which our staff cleared within xxxxx minutes. (again, if true!); C) we may have been remiss in keeping drainage clear on campus, we're working with our facilities staff to institute regular surveillance and clearning (again, if true!); D) we have xxxx and yyy personally monitoring sites aaa and bbb so that we could issue an emergency alert if necessary (again, if true!). Let me know who can best respond with something that faintly resembles my ramblings above (grin). Miscellaneous All of our air conditioners leak into the lab when it rains heavily. This may seem minor, but a bench full of water can damage electronic equipment. Miscellaneous The undeground power to UES1 was destroyed in the floor so construction is required. A HECO temporary power linie is tied to trees and draped through the school hallway at a dangerously low level and jellyrigged into the power panel. HECO will pay to bury the new line under Metcalf Street but UH must pay to bury it from the sidewalk to the building. Miscellaneous There is a storm drain in front of the loading dock, but it quickly clogs and does not appear to have the capacity to handle the rainwater that flows off Spalding and from around the Ewa end of Hamilton this storm drain on March 24 so I don't think neglect is the cause. However, water flowing ar4ound the library goes through the Edmondson boat storage area, across ground with lots of leaves and appears to deposit soil and other material on to the grate of the storm drain leading to it getting clogged. I also think the storm drain needs to be checked to see if it is of appropriate capacity or if it is full of mud inside. Miscellaneous Biomed Sciences Parking Lot - Mid Pacific side: My office assistant normally parks in the Biomed Sciences parking lot adjacent to the fence with Mic-Pacific. She received a call from an acquaintance on March 31 who recommended that she move her truck because the Mid-Pac side of the parking lot had become a debris-carrying stream. When she got to her truck, there was already a bush wedged against her truck. It was not the ditch that overflowed, but water that came from behind the Biomed Sciences Building. I would like to meet with FPMO personnel when they review these areas to discuss what we have seen and our assessment of the sources of the problem. PBRC I have previously reported my concens about potential flooding behind the Biomedical Sciences Building. I need to report additional areas that escaped flooding on March 31 only due to the action of PBRC faculty and staff. PBRC Building Annex: The PBRC Annex flooded during the October 30, 2004 flood. It nearly flooded again on March 31, 2006. When the rain started falling so heavily on 3/31/06, I went to check the back door to the PBRC Annex which is on the St. Francis side of the building. The water ponding in the area near the door was already within one inch of coming into the door. I immediately walked to the Work Coordination Center next door and requested sand bags. After calls to the field, I was told that there were no available sand bags and that I should "go to City Mill" and buy some. In the meantime, PBRC's Information Technology Specialist, Stanford Togashi, dawned rubber boots and rain parka, grabbed a shovel and went out behind the building and started clearning debris that was obstructing the flow of water. Stanford's quick action prevented the water from entering the back door. However, the causes of the near flooding are still present and will require additional solutions. First, much of the water accumulating behind the PBRC Annex is coming from the St. Francis school parking lot. The parking lot has an asphalt berm at its edge with periodic cuts in the berm to relase water which then pours onto UHM land. Ron Lau of FPMO has already talked with St. Francis about this problem. Second, when a new air- conditioning system was installed in the PBRC Annex several years ago, a large cement pad was poured behind the building to house the compressors for the AC system. That cement pad now prevents the ready flow of water behind the building and contributes to the build up. Some sort of culvert through or pipe under the cement pad is now needed. I have pictures of Stanford clearing the debris, etc. The water pouring off PBRC's own roof contributes substantially to the water flow behind the building. PBRC Building Roof: The roof of the main PBRC building leaked in a number of places including several places where it had not leaked before (including the Director's office). My understanding is the PBRC roof is slated for replacement, but has not reached a high priority. CAMPUS FLOODING BUILDING DESCRIPTION STATUS POST POST 617A -- water intrusion from mechanical room next door even when it doesn't rain. POST POST 08 -- water leaking from ceiling. POST POST 110B -- 2 ceiling panels stained from water. ROTC We have a small leak in the admin office of our main ROTC building. Right now it's just staining the ceiling tile. I could see where in the future it could get worse and cause more damage. Saunders The 6th floor, Diamond Head side of Saunders has numerous leaking offices. Have called facilities management umpteen times. They come out, take notes, and leave. Nothing successfully mitigating has been done. Faculty experience wet books, flooded computers and mold. Snyder and When we had Noah's flood (downpour) the other day, the water level on the Maile Way side of the loading dock (the lanai between Snyder and Edmondson) rose to within about Edmondson 1 foot of the top (i.e., lanai level). Had it reached the top, a lot of water would then have drained off in any and all directions on the lanai and might well have flooded halls and rooms in Snyder and Edmondson. This would never have got very deep in either building, but we could have ended up repeating the same long, expensive, inconvenient clean- up scenario of mud, mold, etc., that we did after the Halloween flood of 04. The problem is that the drain at the base of the loading dock is inadequate and apparently plugs up below the dock level and ground level with just about every heavy rain we have. This time, they finally got some facilities management people (I suppose) out there and into the manholes in time to unplug it and drain the water away before it topped the lanai. But a more long-term solution is needed -- one that will work even if no one is here looking when the downpour comes. Let me know if you need to know more details. Thanks for trying to get on top of this whole flooding problem. Snyder and With respect to a specific site, the loading dock area of Snyder and Edmondson Halls. This always floods in even our normal heavy rain. Apparently, the water reached the Edmondson final step (or 5 or 6) the other day, deep enough to worry people on the 1st floor. Extra drainage from, or through the loading docking and into the front of Snyder, would help. Stucturally, the louvre windows of Snyder let in a lot of water. A room above mine flooded as water poured through the windows. That water made its way between the wall and floor, and splashed down, or actually "waterfall" was the word my student used, into my lab. There it filled a monitor with water (and that doesn't work now), poured over a bench and left water over about 40 sq. ft. of lab floor. I understand Dr. Robert's lab also flooded extensively. Sealinig up the windows permanently would help, especially as they're never opened or closed now because most of the mechanisms have deteriorated. An alternative would be to replace all the windows with solid panes. Snyder and The drain at the Snyder-Edmondson loading dock is insufficient. Its limitations are what caused the flooding of Snyder-Edmondson in 2004. Last Friday, the water was less Edmondson than a foot short of overflowing the top of the loading dock and, possibility of entering the buildings. Perhaps a solution would be to allow excess to flow under the loading dock and into the McCarthy Mall. Snyder and Snyder Hall-Edmondson Hall Loading Dock: Water overflowing this loading dock was the source of flood water that inundated Snyder Hall (and perhaps Edmondson Hall) Edmondson during the October 30, 2004 flood. Muddy, debris-filled water again reached within 1-2 inches of the top of the loading dock on March 31. I believe this same area has reached near flood proportions during several heavy rains in the last decade. Although there were calls made to the President's office and elsewhere on 3/31 for assistance to resolve the rising water, it appears that action by Dr. Caroline Blanchard with her laboratory broom did clear some of the debris that had accumulated on the storm drain.

St. John St. John leaky roof; Zoology building lower floor almost flooded. St. John The 6th floor lanai on St. John filled with about 6 inches of standing water due to clogged/blocked drains; water leaked (gushed) into a 6th floor classroom/lab and flooded the floor with considerable water; water leaked down to the 5th floor and flooded several offices, labs, and a graduate student office complex; water on the 5th floor found a hole in the floor that caused water to leak into the herbarium on the 4th floor. St. John I have been compiling info regarding our on-going problems with the roof in St. Johns during the most recent rains. As you may know, the roof has been leaking for the past several decades and eventually needs to be completely replaced, not just patched. Denise Konan stopped by on Monday at Izzie Abbot's request to see the damage done first hand and I took her on a tour of the 5th and 6th floors. Last Friday during the height of the storm. water was literally pouring into a number of offices, labs and classrooms. Additionally, the outdoor lanais overflowed the drains on the 5th and 6th floors, causing water to run down the walls into the lower floors. The following is a list of rooms which leaked and suffered various degrees of damage: 151, 152, 158, 159, 401, 403, 415, 501, 505, 507, 551, 600, 603, 612, 616, 622, the woman's bathroom on the 6th floor is nearly unuseable and numerous leaks in the 6th floor hallways. St. John St John -- Most of the loading bays on Maile Way face mauka and none of them have anywhere for the water to go when it arrives and drains are blocked. There is no new retaining wall to keep the water out of the library lower level. St. John garden annex as well as St. John basement. CAMPUS FLOODING BUILDING DESCRIPTION STATUS St. John The entire 6th floor (under the roof) of St. John building is unusable for laboratory and lecture rooms and dangerous in the halls as well. The Interim Chancellor, Dr. Konan, made a personal survey of the rooms and lanai today. Watanabe Hall In each of two recent periods of very heavy rainfall, the roof of Watanabe Hall has leaked, with water coming into the building near room 435. Watanabe Hall Watanabe Hall -- The leak that John mentioned is just outside Watanabe 435/436 and can be pretty bad. The day we had the big flood, I happened to come in and saw the roof leaking. Put a wastebasket under it and a good fraction of it was filled in the 20 minutes I was there. Over the years, I've reported this leak many times, and though sometimes people seem to come and look at it, even today there is water in the basket that sits under it (from last week's rain) though not as much as during our "great flood". Waikiki Our roof leaks like a sieve and an additional 11 leaks were located during the recent deluges. However, I am cautiously optimistic that this situation will be remedied by the Aquarium R&D money for roof repairs that will, hopefully, be obtained from the Legislature this session. However, other flood-related issues remain. The live animal collection at the Waikiki Aquarium is priceless and requires a complicated mechanical life support system to maintain it in good condition. One major component of this support system consists of pumps to circulate and filter the water. Notably, many of our engangered species (corals, fishes and Hawaiian monk seals) require pumping equipment that operates continuously twenty-four hours a day. Unfortunately, owing to questionable design in the original construction done several decades ago, several of our major system mechanical pump rooms (2-30hp mainsystem pumps, 2-5hp Hawaiian monk seal pumps, and 2-10hp shark tank pumps) are located in sump areas that are below grade. Even though these areas have sump pumps, they are highly susceptible to flooding and this does occur. For example, a recent flood in the pump room for the monk seal pool overwhelmed the sump pump system and ruined both motors. These cost over $5,000 to replace. Other similar incidents have occurred elsewhere in the Aquarium. The Aquarium would appreciate your consideration regarding any monies that might become available for us to remedy this unacceptable situation. Additionally, funding that could be allocated towards a water alarm system that could promptly alert staff to flooding in any of our pump rooms would also be appreciated. Webster Hall The location is Webster Hall 4th floor and our understanding from Facilities is that the roofing seal is not covered by the "contract warranty". As a result, various offices have rain leaks that consistently damage ceiling tiles, light fixtures and sometimes the computer equipment, office and pesonal materials in the offices. The specific locations are 402, 403, 404, 432, 433, 445 and the hallway fronting room 405.
