Kirkwood Blvd. ZA16-037 & TRER16-0128 TD Ameritrade is requesting approval of an extension of date of Case ZA16-037, Resoltion No. 16-022, Specific Use Permit for Temporary Construction Trailers and Approval of a Tree Conservation Plan and Tree Removal Permit for their DFW Campus at Southlake located at 1051 and 1801 W. Kirkwood Boulevard. 2 Aerial View This is an aerial view of the property which located north of W. Dove Road and is bounded by SH114 along the west, and W. Kirkwood Boulevard along the north and east boundaries. 3 Approved Site Plan For reference, this is the approved site plan for the TD Ameritrade site – The site plan was approved on April 19, 2016. 4 Temporary Construction Access Exhibit Bridge to be adjusted A Specific Use Permit was approved on June 7, 2016 that allowed additional construction trailers exceeding the minimum single 2,000 square foot trailer permitted as an accessory use under the Zoning Ordinance. A condition of the SUP approval was that the applicant would need to return directly to City Council for an extension if the access drive connecting to W. Kirkwood Boulevard at T.W. King was not completed by December 31, 2016, otherwise the SUP would expire. Due to delays in obtaining a permit from the Corp of Engineers to construct the bridge across the floodplain, flowage easement and drainage channel, the applicant will need to request the extension. As a part of the extension request, the applicant is proposing an alternate temporary construction access that can be completed earlier than the permanent access in order to help divert the majority of construction traffic further away from the Kirkwood Hollow neighborhood. To accomplish this, some additional trees will need to be removed that were not shown on the original Tree Conservation Plan. Additionally, to meet the requirements for a permit from the Corp of Engineers, the bridge location may needs to be adjusted slightly which will also require removal of additional trees. This exhibit shows the proposed temporary construction access driveway and the location of the bridge area to be adjusted. The applicant proposes having the temporary construction access driveway open and completed by January 31, 2017 and is requesting to allow the temporary construction trailers either for a period of 90 days past final certificate of occupancy received but not to exceed two years from original approval date of June 7, 2016. 5 Original Tree Conservation Plan Existing Tree Cover  - 65.3% Required % of existing cover to be preserved - 40% Proposed % of existing cover to be preserved - 76% This is the original tree conservation plan submitted with the approved Site Plan. The applicant requested that Tree Preservation Ordinance No. 585 –D be the controlling document for this site plan. The species of trees in this area consist primarily of post and blackjack oaks, american elm and red cedar. The existing tree cover is approximately 65% of the site and requires that a minimum of 40 % of the existing tree cover is required to be preserved. Under the originally submitted Tree Conservation Plan the applicant planned to preserve a minimum 76% is proposed to be saved. 6 Proposed Tree Conservation Plan Existing Tree Cover  - 65.3% Required % of existing cover to be preserved - 40% Proposed % of existing cover to be preserved - 72% This is the proposed Tree Conservation Plan which changes the originally planned 76% preservation to approximately 72% preservation of existing tree cover. Once again, a minimum of 40% is required to be preserved. 7 Detail of Revised Area The revised Tree Conservation Plan shows an additional 3.73% of existing tree cover to be removed for the Temporary Access Road, the bridge realignment and revised slope grading around the bridge and other portions of the permanent access road. Approximately 72.27% of the existing tree cover is proposed to be preserved which meets the Existing Tree Cover Preservation Requirements of the Tree Preservation Ordinance. No variances are requested. 8 Detail of Revised Bridge Area 9 PZ Action At its September 22, 2016 meeting, the Planning and Zoning Commission voted 5-0 to recommend approval of the revised Tree Conservation Plan and the Tree Removal Permit. 10 Questions? 11 Approved Landscape Plan Additional screening added This is the landscape.
