E. Within a single phase of any Concept Plat, individual block perimeters may exceed the maximum by 25% <br />provided that the average of all block perimeters in the phase does not exceed the maximum <br />F. The Director of Engineering may waive the block perimeter requirements or maximum dead-end street lengths <br />when steep slopes in excess of 25% exist and/or where freeways, waterways, railroad lines, preexisting <br />development, tree conservation areas, stream buffers, cemeteries, open space or easements would make the <br />provision of a complete block infeasible. <br />G. Where the block pattern is interrupted by public parkland, that is open and accessible to the public, pedestrian <br />access points to the parkland shall be provided with a minimum spacing equal to '/2 of the maximum block <br />perimeter. <br />Section 7.10 Access. The following Subdivision Access Standards shall be applied. <br />A. Stub Streets. <br />1. Where a development adjoins unsubdivided land, stub streets within the new subdivision shall be <br />extended to the meet maximum block perimeter standards. <br />2. The stub street must be extended to the boundary of the abutting property to the point where the <br />connection to the anticipated street is expected. <br />3. Stub streets must be located so that the portion of the block perimeter located on the subject property <br />does not exceed 50% of the applicable block perimeter maximum. <br />4. If a stub streets exists on an abutting property, the street system of any new subdivision must connect to <br />the stub street to form a through street. <br />5. When the entirety of a creek crossing is in the subdivision, the crossing must be in a single phase in its <br />entirety. <br />6. Where a stub street is provided, a barricade using a design approved by the Director must be constructed <br />at the end of the stub street, pending the extension of the street into abutting property. A sign noting the <br />future street extension shall be posted at the applicant's expense. <br />7. The Director may eliminate the requirement for a stub street when: <br />a. Steep slopes in excess of 25%; freeways, waterways, railroad lines, preexisting development, <br />stream buffers, cemeteries, open space or easements would make the provision of a stub street <br />infeasible; or <br />b. A high intensity nonresidential use is located adjacent to a proposed residential subdivision. <br />B. Cross Access. <br />1. All lots abutting a street other than a neighborhood street shall comply with the following standards: <br />a. Internal vehicular circulation areas shall be designed and installed to allow for cross -access <br />between abutting lots; <br />b. When an abutting owner refuses in writing to allow construction of the internal vehicular <br />circulation on their property, a stub for future cross -access shall be provided as close as possible <br />to the common property line. <br />
