Property lies within an industrial zone LI-CO with similar warehouse buildings ranging between 115,000 square feet to 160,000 square feet. This site offers a reasonable location for large industrial manufacturing warehouses as it is located in the Desired Development Zone. No critical environmental features, no steep slope. In order to facilitate this type of development, significant levelling is required to enhance maneuverability into the loading docks, allowing trucks to operate safely. 5 BACKGROUND (CONTINUED) • • • • Existing natural ground level grades are as much as 15 feet below the finish floor elevation for the proposed new buildings. Due to the topography of the site and the size of the proposed buildings (each approximately 4 acres in size), in order to accomplish the operational criteria, fill up to 17 feet is necessary. Therefore, staff is agreeing with retaining walls provided to structurally contain the fill and minimize the amount of grading. Accessibility to portions of the building would not be achievable without this variance. 6 EXISTING CONDITIONS • Tall grasses, weeds and tree cover. (Hackberry, mesquite and chinaberry less than 19in) North 7 High Point TOPOGRAPHY • The site mostly slopes from south to north ranging between 525 to 503. Slopes vary but do not exceed 15% in any direction except for manmade drainage swale on the north side of the property. NTS North 8 VARIANCE REQUEST • To allow fill in excess of four feet and up to 17 feet within the Desired Development Zone.

Retaining Walls • Enhancing stability. NTS North 1 1 VARIANCE RECOMMENDATION Staff has determined that the required findings of fact have been met and recommends the following condition: • Provide structural containment of fill with retaining walls. 2 1 QUESTIONS & COMMENTS 3 1
