D. tdcDon�� ' �"'� May 10, 19'tl. � �"JO"`"' DRIVEWAY AT 37ZO COLBY AVENUE arv oF �vErc�11. ev�a�tr. wnstiirvc�or+ I received a request to investigate the driveway at 3720 Colby Avenue. The property owner here complained of dragging the bottom of her � car when entering and exiting the driveway. The present condition of the improvements at 3720 Colby Av�nue consist of a single car garage with a ramp from strnet level down to the basement level � where the garage is located. Prior to the construction of the Colby Avenue Project, the driveway ramp had been constructed from the existing curbline across a certain portion of the City right- of-way into the garage. The original design of this driveway had , a 21. 58 slope. The widening of Colby Avenue decreased the curb to house dimension by 7. 5 feet. The driveway at present has a 31. 4� slope. The combination of the 10� driveway apron and the j/� slope into the garage make it very difficult to obtain a I transition which allows an automobile to pass over the .�e r»;r�` The Time Saver Standard Publication gives the average dimension of vehicles showing maximums and minimums including the front ap�roach angles , rear approach angle, and brealc over angles , clearance, the maximun and minimum widths and the wheel bases . The maximum recommended break over angle is 16.2° of�-29� . The particular driveway in question has a combined break over angle of 40 .9� which is considerably greater than the recommended maximum. Corrective alternatives liave been considered for this driveway. Solution #1 - A solution to the problem would be to write the property owner at 3720 that the City has replaced the driveway and can make no further improvement on private property and there are no legal obligations toward the ingress and egress to the driveway because due to phys�cal conditions it is not pratical t� . supply a driveway to this garage even thouqh it had been �� prior to the improvement of Colby Avenue . Solution #2 - Contact the property owner, obtain permission to block the existing garage entrance with a concrete bulkhead, fill the driveway area and leave no garage for the property owner. i have talked briefly to the property owner here about blocking the driveway. Should this be an answer to the problem, the prop�rty owner requests that the City provide a carport as a replacement for the lost driveway. The zoning in this particular area is R-4 which requires a 5-foot side yard setback. The house on this location is built on two lots for a total of 50-foot front. The house itself is 24-feet, leaving a 10-foot side yard on the north side and a 16-foot side yard or: the south side. T�h�''s' w9uld preclude the construction of a carport of any size on the`�t�i�side. A cost estimate for filling the driveway entrance and installing a concrete bulkhead in place of the door would be: Form, •}�e and strip the entrance with concrete wall would require 1.95 cubic yards of concrete @ approximately $225 a yard or $440 .
