Letter of Request from the Orange County Board of Education Attachment 2. OCS Cedar Ridge High School Capital Project Ordinance TELEPHONE NUMBERS: Hillsborough 732-8181 Chapel Hill 968-4501 Durham 68$-7331 Mebane 336-227-2031 PURPOSE: To approve a request from the Orange County Board of Education to increase fire fighting capacity for Cedar Ridge High School. BACKGROUND: Recently Civil Consultants, Inc. conducted a study of several fire protection system options for Cedar Ridge High School for the Orange County Board of Education. According to the infom~ation contained in the attached letter (Attachment 1 of this abstract), the fire suppression capacity, as currently designed, meets minimum State requirements. The Board of Education is interested in taking additional steps to improve safety by increasing the capacity beyond what the State requires. The consultants identified two options: Option #1 -Construction of a private 200,000 gallon cylindrical ground storage tank near the corner of Orange Grove Road and Grady Brown School Road at an estimated cost of $350,000. Option #2 -Construction of a new 250,000 gallon elevated water storage tank at the same location as in Option #1 at an estimated cost of $600,000. Details regarding each option are included in Attachment 1 of this abstract. In keeping with the Commissioner's Policy on Planning and Funding School Capital Projects, the Superintendent has submitted details regarding the change order, in writing, to the County Manager (Attachment 1). The District requests that the Commissioners approve a reallocation of project savings (cun-ently budgeted in the project Contingency) to complete Option #1. z FINANCIAL IMPACT: Currently budgeted project contingency totals $800,000. Should the Board approve the request to complete Option #1 (an estimated cost of $350,000); the project Contingency account would be reduced to $250,000. - RECOMMENDATION(S): The' Manager recommends that the Board of County Commissioners approve a request from the. grange County Board of Education to increase fire fighting capacity for Cedar Ridge High School at an estimated cost of $350;000. k Orange County Board of Education Randy Bridges Superintendent Board Members: Keith Cook, Chairman Brenda Stephens, Vice Chair Robert gateman Susan Halkiotis David Kolbinsky Delores Simpson Dana Thompson 200 );ast King Street Hillsborough, NC 27278 Telephone: 919-732-8126 FAX: 919-732-8120 ~p~JN~, 0 ~ Y84A MEMORANDUM TO: John Link FROM: Randy Bridges RE: Cedar Ridge High School Fire Protection Water System DATE: May 29, 2001 During the May 21, 2001 Orange County Board of Education meeting a proposal for increasing the fire fighting capacity for Cedar Ridge High School was presented to the Board. Please know that we meet the minimal requirements as established by the state with the current system of water pressure. However, we feel that to make Grady Brown Elementary School and Cedar Ridge High School as safe as possible, additional steps should be taken. I have enclosed a copy of the plan to place a water storage tank on the Grady Brown campus to meet the needs of both schools relative to fire fighting capacity. As you are aware, Cedar Ridge High School came in under budget. The Board has approved a request to the Commissioners to reallocate some of the savings to cover the cost for the water tank. We are asking that you present this information to the Commissioners for their consideration and approval at your earliest convenience. If additional information is needed, please let me know, Thank you. /ha Enclosure cc: Orange County Board of Education Sandra Tinsley Mike Parker Tony Whitaker Steve Halkiotis Ricardo Gonzalez Ken Redfoot Orange Cnunty Schaals "Providing educutiana! opportunities fnr successful futures.

King Street Hillsborough, NC 27278 Re: Cedar Ridge High School Fire Protection Water System Dear Dr. 'Halkiotis: With the help of Finkbeiner Pettis and Strout, Inc., we have completed a study of several fire protection system options for the referenced site. After assessing the basic options and a few variations thereof, we suggest consideration of two viable fire protection options, as follows: .QPTION #1 -Construction of a private 200,000 gallon cylindrical ground storage tank near the comer of Orange Grove Road and Grady Brown School Raad. The tank would be approximately 45 feet high (overflow elevation t 745'), to provide enough system pressure to meet the necessary hydrant and sprinkler flow requirements without the need for boaster pumps. Only the top half of the tank volume (100,000 gallons) will be useful for meeting site fire protection requirements, since anything below elevation 725' would not be high enough to create the minimum required pressure. The bottom 100,000 gallons of water would only be a necessary structural support for the water above it. The tank would be fitted by the available pressure in the Tawn of Hillsborough s public water system, but water from the tank could not cycle back into the Town's system since the tank height would be far too law to allow any backflow under normal condition onlAsfor fi e ~ protection ~ mgat on~ orsather non-drink nlg contain non-potable water, usable y P purposes. The non-potable status of the system has the fallowing negative consequences: a. Anew. non-potable waterline from the tank to the high school will be required, essentially parallel to the new potable waterline already being constructed by the project for the Town of Hillsborough. b. The onsite looped waterline and hydrant system designed by the Architect will require significant redesign. This onsite system is currently under construction and is a critical path item for project completion. 3622 Lyckan Parkway Suite 3003 ^ Durham, N.C. 27707 c. The existing domestic water service line extending from the onsite loop will not be usable as designed, but will instead require a connection to the new public (potable) .waterline being constructed by Orange County Schools along Grady Brawn School Road. This work has significant cost and schedule implications. d. The water in the tank system may require periodic discharge and replacement to maintain a bare minimum level of water quality. The water used for this purpose would probably be billed from the Town of Hillsborough at the prevailing domestic water rate. In addition to the above, the ground level tank has another unappealing characteristic. The tank overflow elevation will limit and define the available pressure and flow conditions of the onsite hydrant and sprinkler system, at a level far less than the potential that could exist otherwise. In other words, the Town's water system has quite good static pressure at the school site, but it doesn't have the ability to maintain adequate pressure during high flow (fire flow) conditions, due to various water system constraints in the area. Storing the fire protection water in a relatively low- height tank sacrifices the "quite goad" pressure potential for more water volume at "merely adequate" pressure. If future public system improvements are made by the Town or others, the ground level tank option will not allow the school to benefit from the increased capacity, because the tank overflow elevation will always govern the available pressure and flow for the site. Despite the above complications, the ground level tank option does qualify as feasible and adequate. The estimated cost of Option #1 is about $ 350,000, which includes the cost of onsite waterline re-configurations. The system could be in service before the June, 2002 school occupancy date. OPTION #2 -Construction of a new 25D,000 gallon elevated water storage tank at the same location as in Option #1. This tank would be of a conventional golf ball-and-tee shape, and approximately 132 feet high (overflow elevation t 832'). This height would match the hydraulic pressure gradient of the Town's water system in the area, creating a fully compatible. and integrated component of the public water system. This option would greatly increase the degree of fire protection far the adjoining Grady Brown Elementary School, and for Town water customers in the area at large. This compatibility with the Town's pressure gradient will allow the water in the tank to cycle with the normal flow of water in the Town's system, maintaining a fully potable condition in the tank and in connected lines. In addition, the proposed tank volume is large enough to be viable as a municipal asset. For these reasons, this option assumes that the tank will be owned and maintained by the Town of Hillsborough, as part of the Town's public utilities infrastructure. In addition to the obvious benefits of an elevated tank as described above, Option #2 has other meaningful benefits, as follows: a. No parallel non-potable waterline would be required along Grady Brown School Road. -2- 6 b. The onsite waterline loop and hydrant system can be constructed as currently designed. c. The domestic water service line for the school site can be constructed as currently designed. d. No substantial impact to the school's construction schedule or onsite construction cast would be anticipated (assuming a timely decision to implement this option). The total estimated cost of Option #2 is $ 600.000. The tank could be in service before the June, 2002 school occupancy date.
