Parking shall be permitted in a front yard, provided it is set back at least 50 feet from the street right-of-way line abutting and adjacent to residential districts, and at least 15 feet from the street right-of-way line of any other yard. When parking is proposed within the front yard along the 10th Street frontage, then a pier-fence-hedge combination shall be installed and maintained near the sidewalk in the 10th Street front yard portion of a lot, in order to screen the view of off-street parking. Stone/masonry piers shall be 36 inches to 42 inches in height, at least 24 inches by 24 inches in dimension, located on sixteen-foot to twenty-foot centers, and include a flagstone or masonry cap. The piers shall be connected by black aluminum fencing of 30 inches to 36 inches in height. The pier-fence-hedge combination shall be located in a planting bed with low evergreen shrubs planted on three-foot centers on the streetscape side of the piers and fence. The Borough Council may approve, at its sole discretion and after review of sufficient design related documents, alternate design standards to the pier-fence-hedge combination specified above if the alternate design provides similar or better results.
