Your comments have been addressed, and the corrected site plan and comments are included. All the comments have been appropriately addressed on the drawings. The explanations of a few particular comments are as follows: "Site Plcm Cheekli.Sl - co11 mellt // 5" There are no new outdoor lighting fixtures according to the electrical engineer; therefore they are not shown on the site plan. "Site Plall Checklist - co111meiit 11 7" The dumpster addressed, which is an existing dumpster, does indeed sit on a concrete pad, nor is it affected by this addition. As for the screening requested, Tom Sullivan, with the Frederick County School Board, spoke with the Planning Department on 12/3/97 and confirmed that such screening will not be necessary. "Site Plcm Checklist - com lnew.y ll 9 & 10" The requested parking space calculations have been added to the drawings, and the Frederick County School Board has sent a letter to the Planning Department to address the discrepancy between the parking required and the parking provided. "Site Plcul Checklist - commelN 11 11 " Per my telephone conversation with you on 12/3/97 and site plan approval by the School Board, the sidewalk network currently indicated on the site plan is adequate and does not need to be changed. 9715L002.WPD Department of Planning and Development Page 2 December 19, 1997 "Sheet C2 - commeill 1/ 4" The "well lot easement" in question was required when that well was the school's water source, but is no longer- effective because the school receives their water from the city. Per my conversation with Curtis Walker (Frederick County Schools) on 12/3/97, the proposed asphalt play area is allowable where it is currently shown on the plans. All other review comments have been appropriately addressed on the plans as you have requested. The required review agencies for these site plans are the County Engineer, Fire Marshall, and the Planning Department, according to Evan Wyatt. Submittals have been made to these agencies, and the approved site plan from the Engineering Department is included with this letter. I have not yet received a response from the Fire Marshall; when a response is received, it will be addressed and sent to you. Sincerely, OLIVER, WEBB, PAPPAS & RIIUDY, INC. Trevor M. Kimzey, E.I.T.

Construction of additional parking spaces is not included in the project. The existing amount of parking spaces at the school is more than adequate for the anticipated increase in staff and visitors during the regular school day. In addition, during the planning process, we reviewed attendance data as a result of special events such as concerts, plays, and various meetings held throughout the school year. We do not expect attendance at these events to increase significantly following the completion of the addition. We feel the number of parking spaces which currently exists at Armel Elementary School is sufficient for special events held at the school. If you should have any questions or concerns with regard to this matter, please do not hesitate in contacting me at your earliest convenience.

(2) If inspection indicated poor alignment, debris, displaced pipe, infiltration or other defects, correct such defects and reinspect. 02720-4 9715 SITE WORK DIVISION 2 B. CONNECTION TO EXISTING STORM SEWER: 1. Tap Connections: a. Make connections to existing piping and underground structures, so that finished work will conform as nearly as practicable to requirements specified for new work. b. For branch connections from side into existing 24" or larger piping, or to underground structures, cut opening into unit sufficiently large to allow 3" of concrete to be packed around entering connection. Cut ends of connection passing through pipe or structure wall to conform to shape of and be flush with inside wall, unless otherwise indicated. On outside of pipe or structure wall, encase entering connection in 6" of concrete for minimum length of 12" to provide additional support or collar from connection to undisturbed ground. (1) Provide concrete which will attain minimum 28-day compressive strength of 3000 psi, unless otherwise indicated. (2) Use epoxy bonding compound as interface between new and existing concrete and piping materials. C. Take care while making tap connections to prevent concrete or debris from entering existing piping or structure. Remove debris, concrete, or other extraneous material which may accumulate. C. BACKFILLING: 1. General: Conduct backfill operations of open -cut trenches closely following laying, jointing, and bedding of pipe, and after initial inspection and testing are completed. D. FIELD QUALITY CONTROL: 1. Maintain lines and grades by using a stringline or batterboards with grades marked at intervals no greater than 50' , or by laser. 2. Flushing: Flush all storm sewers with water in sufficient volume to obtain free flow through each line. Remove all silt and trash from inlets just prior to final acceptance of the work. 02720-5 9715 • • SITE WORK DIVISION 2 3.
