The patches are only temporary. Temporary patches are used to surface the area where the asphalt has been removed until the asphalt pavement can be replaced. You can expect some settling to occur this is normal and to be expected. We have two work orders open (#'s 244451 & 244995) to come back out to do permanent restoration in the summer. Should the patch sink to a dangerous level please call the Bureau of Utilities at 410-313-4900 and we will add additional patch. Please feel free to give us a call if you have any additional questions or concerns.
