Water quality will be addressed by the installation of a nonproprietary water treatment device. The total site area of the Legacy School site is 5 acres. The area of analysis for water quality is defined by the 1.54 acres of disturbance as shown on the exhibits. This does not include the linear area required to install the proposed water line to the fire hydrant. Based on the disturbed area of the project, the total phosphorous load reduction for this project is 1.17 Ib.yr. See Sheet 6 for Biofilter contributing drainage areas and land cover. WATER TREATMENT SUMMARY FOR BIOFILTER DA.A: The Bioretention filter is located in a drainage area that contains 1.11 acres. The Biofilter is a level 2 design and reduces TP 1.4 lbs/year.

When work takes up part of a lane on a high 'volume roadway,- vehicular traffic volumes; vehicle mix, speed and capacity should be analyzed to determine whether the affected lane should be closed. Unless the lane encroachment analysis permits a remaining lane width of 10 feet, the lane should he closed. If the closure operation is on a Limited Access highway, the minimum lane width is it feet. Ogtion: 4. The ROAD WORK AHEAD (W20-1) sign on an intersecting roadway may be omitted where drivers emerging from that roadway will encounter another advance warning sunt prior to this activity area Standard: 5. A shadow vehicle with either an arrow board operating in the caution mode, or at least one high- intensity amber rotating, flashing, tv oscillating light shall be parked 80' -120' in advance of the first work crew. 6. Vehicle hazard warning signals shall not be used instead of the vehicle's high-intensity g � g natty amber rotating, flashing, ' oscillating lights. Vehicle hazard warning signals can be used to supplement high-intensity amber rotating, flashing,'W", oscillating lights. 7. Taper length (L) and channelizing device spacing shall be at the following: Speed Limit (mph) Location will include (1) the closure of the southbound shoulder to allow exposure of the existing 30" NA 0-35 36+ Transition Spacing 20' 40' Travelway Spacing 40' 80' Construction Access' ' $o' 12ti` Spacing may be increased to this distance, but shall not exceed one access per % mile. On roadways with paved shoulders having a width of 8 feet or more, channelizing devices shalt be used to close the shoulder in advance of the merging taper to direct vehicular traffic to remain within the traveled way. 8. The buffer space length shall be as shown in Table 6H-3 on Page 6H-5 for the posted speed limit. 9. A truck -mounted attenuator (TMA) shall be used on Limited Access highways and multi -lane roadways with posted speed limit equal to or greater than 45 mph. 10. When a side road intersects the highway within the temporary traffic control zone, additional traffic control devices shall be placed as needed. 1: Revision I - 4/1/2015 April 2015 Lane Closure on a Two -Lane Roadway Using Flaggers (Figure TTC-23.1) n NOIltt1S NaDE)VIJ 1: Revision 1- 4/1/2015 MM G20-2 (V) 500 501-100, SEE NOTE SHADOW VEHICLE REQUIRED SEE NOTE 4 503 100' - 'FLAGGER STATION SEE NOTE 2 Page 6H-52 April 2015 Page 6H-53 Typical Traffic Control Lane Closure on a Two -Lane Roadway Using Flaggers (Figure TTC-23.1) NOTES Guidance: 1. Sign spacing distance should be 350'-500' where the posted speed limit is 45 mph or less, and 500'-800' where the posted speed limit is greater than 45 mph. 2. Care should be exercised when establishing the limits of the work zone to insure maximum possible sight distance in advance of the flagger station and transition, based on the posted speed limit and at least equal to or greater than the values in Table 6H-3. Generally speaking, motorists should have a clear line of sight from the graphic flagger symbol sign to the flagger. Option: 3. Where Right -of -Way or geometric conditions prevent the use of 48" x 48" signs, 36" x 36" signs ma robe used. Standard: 4. Flagging stations shall be located far enough in advance of the work space to permit approaching traffic to reduce speed and/or stop before passing the work space and allow sufficient distance for departing traffic in the left lane to return to the right lane before reaching opposing traffic (see Table 6H-3 on Page 6H-5). 5. All flaggers shall be state certified and have their certification card in their possession when performing flagging duties (see Section 6E.01, Qualifications for Flaggers) 6. Cone spacing shall be w ..a... 7. A shadow vehicle with at least one high intensityamber rotating, . .-_. oscillatingg light shall be parked 80'-120' in advance of the first work crew. Option: 8. A supplemental flagger r may be required in this area to give advance warning of the operation ahead by slowing approachin traffic affic prior to reachingthe he flagger station or queued traffic. Guidance: 9. I the ueue o tra is reachesthe BE PREPARED TO STOP (W3-4) sign then the sign '' _ should be readjusted at greater distances. 10. When a highway -rail crossing exists within or upstream of the transition area and it is anticipated that queues resulting from the latae closure might extend through the highway -rail grade crossing, the temporary traffic control zone should be extended so that the transition area precedes the highway -rail crossing (vee Figure TTC-56 for additional information on highway -rail crossings). Standard: 11. At night, flagger stations shall be illuminated, except in emergencies (see Section 6E.08). Option: 12. Cones may be eliminated when using a pilot vehicle operation or when the total roadway width is 20 feet or less. 13. For low-volume situations with short work zones on straight roadways where the flagger is visible to road users approaching from both directions, a single flagger, positioned to be visible to road users approaching from both directions, may be used (see Chapter 6E). NOW PT1? S `cin Center to Center _'a5 FtvetN x°= 8 Feet 1: Revision 1- 4/1/2015 General Notes 1. This project is classified as a Traffic Management Category I project. Work during the project C.I.: will include (1) the closure of the southbound shoulder to allow exposure of the existing 30" NA waterline, and (2) the closure of the southbound lane and center turn lane to permit the o installation of a new 8" waterline, and (3) the closure of the northbound lane, centerline, and 1711010 shoulder to permit the installation of a new 8" waterline. Temporary Traffic Controls for the closure N of the lanes will generally conform to TTC 23.1 with the difference being the closure of two lanes 7/24/18 rather than the one lane depicted in TTC 23.1. Rumble strips will not be used unless directed by w�Npr,E VDOT. _ O 2. The project is located on Route 11, Valley Pike Road in Frederick County south of Stephens o U City. Route 11 is a major collector road with <5% trucks, a traffic volume of 5,000 vehicles per Q- day, and a posted speed limit of 55 mph at the site. The existing road consists of one southbound lane, one northbound lane, and a center turn lane. 3. The work consists of replacing a waterline across Route 11 to provided fire service for the N school. Q z 4. The work zone will be approximately 3,000 feet in length on Route 11 and will be staged to , allow traffic flow. 5. The work zone will consist of a temporary closure of the southbound shoulder, then closures v of the center turn lane and the southbound lane, then closure of the center turn land and the W northbound lane and northbound shoulder in accordance with the requirements of the Virginia Work Area Protection Manual (VWAPM) and the Manual of Uniform Traffic Control Devices (MUTCD). Ld (Ya Southbound traffic will be directed to the northbound lane using flaggers. Northbound traffic will be directed to the southbound lane by flaggers. Accommodations for left and right turns through the U ~ work area will be accomplished by providing breaks in the channelizing devices. O 6.
