Site Plan/CUP Application PROJECT NARRATIVE The Headwaters Academy, Inc. (HWA) proposes to reuse the existing building at 1005 Durston Road to house its Administration Staff on the second floor as well as house community activities on the first level such as meetings for community associations, clubs and groups; host public presentations and functions; and be available for general public rental. HWA also proposes to build a new building on the property, southeast of the existing house, to house the student classrooms and activity areas. In addition, HWA will improve the site by adding a new water service to the new building, fire hydrant, parking facilities with 59 new parking spaces, and landscaped grounds as shown in the accompanying documents and plans. HWA proposes to reuse the existing garage as a garage and construct new curbed asphalt driveway to access the garage. New pedestrian walkways are proposed for the spaces surrounding the buildings, new and existing and sheltered bike parking is proposed to be located north of the new classroom building. The north fields of the property are proposed to be left open for outdoor activities. The proposed project timeline would have construction starting early this summer, once Site Plan/CUP and Building Permit approval have been received, to allow for occupancy of the project by early spring 2021. We request to submit this project for Building Permit review concurrently with the Site Plan/CUP project review. RESPONSE ADDRESSING REQUIRED CODE CORRECTIONS Planning Comments 1.
