HEARING DATE: March 8, 2011 STAFF REP.: Marcie Diamond, Assistant Director of Planning LOCATION: Southeast side of S.H. 121, south of Sandy Lake Road SIZE OF AREA: 5,625 square feet of property CURRENT ZONING: PD- 224 -HC (Planned Development 224 - Highway Commercial) REQUEST: A zoning change to PD- 224R -HC (Planned Development 224 Revised - Highway Commercial), to revise the Concept Plan and attach a Detail Site Plan to permit a Valve Site. APPLICANT: Owner: Steve Park DCCCD 1601 S. Lamar Street Dallas, Texas 75215 972 - 860 -5130 Applicant: Will E. Lee Texas Midstream Gas Services 100 Energy Way Fort Worth, Texas 76102 817 - 502 -4712 FAX: 817 - 945 -4712 HISTORY: This property was zoned a Light Industrial district in 1983. In April 2003, the Planning and Zoning Commission called a public hearing for a portion of this property to amend the designation on the Future Land Use Map from Regional Retail and Light Industrial /Showroom to Freeway Commercial. Also at that time, the zoning classification of Light Industrial was recommended to be changed to Highway Commercial to encourage the development of well - designed retail, commercial and /or office development, versus big -box tilt -wall industrial buildings along the frontages of S.H. 121 and Sandy Lake Road. City Council approved the rezoning and Land Use Map amendment in May of that year. ITEM # 10 Page 1 of 3 In June of 2007, Council approved a change in zoning to allow college and ancillary uses on 37 acres of property and to attach a Detail Site Plan for Phase 1 to allow the construction of a 37,000 - square -foot multi - purpose building on approximately 10 acres of property. Since that time, phase one building and parking has been constructed. TRANSPORTATION: State Highway 121 is designated as a freeway with 600' right -of -way. When built to standard it will contain 10 main lanes and 6 service road lanes. Sandy Lake Road is a four -lane divided thoroughfare within right -of -way sufficient for a six -lane road. SURROUNDING LAND USE & ZONING: North- Light Industrial and undeveloped, LI South -Light Industrial and mini - warehouses, LI and S- 1204 -C /LI East - Light Industrial and undeveloped, LI West - City of Grapevine, undeveloped COMPREHENSIVE PLAN: The Comprehensive Plan of May 1996, as amended, shows the property as suitable for light industrial /showroom uses. DISCUSSION: The applicant is requesting an amendment to the existing PD for the North Campus of Northlake College to permit the construction of a valve site to support the gas pipeline that has recently been installed parallel to SH 121. As municipalities have limited review and approval authority over underground pipeline locations, zoning and site plan regulations are applicable only when above ground facilities are planned. On December 15, 2010, the City of Coppell's Engineering Department issued a Right -of -Way Use Permit to allow the construction of this 8" natural gas pipeline under the right -of -way of Sandy Lake Road. This permit was issued subject to the following comment: "Permit for pipeline only. Any above ground improvements will require separate zoning /council action. Approval of this pipeline installation does not guarantee future approval of any above ground improvements" Midstream Chesapeake is planning to construct this valve site, with screening and landscaping along the frontage road of SH 121, south of Sandy Lake Road. While staff would prefer this facility being relocated internal to the site, the location of this valve site and it's proximity to SH 121 is dictated by the location of the pipeline. The applicant is ITEM # 10 Page 2 of 3 providing a solid screening wall and landscaping to make this facility as least visually obtrusive as possible. As required by the property owner (DCCCD), the brick on the proposed six -foot tall brick wall will match the brick color of the college building and this wall shall "completely hide the valve site from public view ". The landscape plan has be revised from it's initial submittal to reflect the landscape materials used in the remainder of the site. Crape Myrtles are planned adjacent to the frontage road of SH 121 and Cedar Elms facing the existing campus buildings and parking. Shrubs (mixture of Dwarf Glossy Abelia and Indian Hawthorn) are planned along the perimeter of the brick wall on all four sides. Potential interference with above and underground utilities limits the use of overstory trees on the north and south sides of the site. There is currently no irrigation (water lines) serving this site. The applicant is proposing a 5 -foot tall water storage tank with solar panels to provide water for the proposed landscaping. Access for this site will be via a 20 -foot wide driveway from the service road of SH 121. As of this date, TxDOT has permitted a temporary driveway to serve this site. It is anticipated that once zoning and site plan approvals are granted for this use and it is constructed, TxDOT will issue a permit for a permanent driveway. The driveway will be concrete and will meet Coppell's construction standards. RECOMMENDATION TO THE PLANNING AND ZONING COMMISSION: Staff is recommending APPROVAL of PD- 224R -HC, Northlake College, to revise the Concept Plan and attach a Detail Site Plan to permit a Valve Site, subject to the following condition: 1. A copy of TxDOT permit for a permanent driveway shall be submitted to the Engineering Department. ALTERNATIVES: 1. Recommend approval of the request 2. Recommend disapproval of the request 3. Recommend modification of the request 4. Take under advisement for reconsideration at a later date ATTACHMENTS: 1. Concept Site Plan 2. Detail Site and Landscape Plan 3.
