• B. Certificates of Appropriateness 1) Blanket COA for street identification and traffic control signs Mr. Duvall read the Staff report and circulated photographs. Mr. Carl Litrell presented the signs in question. Ms. DeRose stated that she was opposed to handing out a blanket order for a COA. However, she felt that the ordinance called for some flexibility .as long as there was a strict interpretation of the ordinance. She stated that all markers that presently exist which may be changed in the future could be identified under the 'COA, and that the COA make it clear that there be no deviations from the signage currently being used. Should such markers deviate from said COA, then, a new COA should be required. Ms. DeRose stated that the traffic signs are a state issue. -An identification of where they are presently located should be noted in case of future replacement, in which case a new COA should be sought, but, as far as installing new ones, that, again is an issue of the state. Mr. Duvall asked Ms. DeRose about the duration of the COA. Ms. DeRose suggested that a new blanket COA be requested annually, provided no changes be made from the original COA, and that the renewed COA could be performed by Staff. Mr. Oxian suggested a standards and maintenance committee to approve later requests rather than having the whole committee involved every time a question comes up or a request is made where approval must be met. The committee would be on call for .any .questions and decisions to be- made. Mr. Litrell made a • demonstration of how the street signs would be mounted on poles rather than directly on the posts with metal bands which they are currently being mounted on now. A UtChannel pole was used in the demonstration. Ms. DeRose asked Mr. Litrell to identify every location, or potential location, where these new poles would be placed. Two COA's were discussed. One for traffic control and one for street signs. Mr. Talley stated that the new traffic control signs were larger than the old signs. Mr. Oxian questioned whether the new traffic control signs, when being replaced, would remain the same size they are now (i.e. 12 x 18) or would they be the size of the new signs (i.e. 18 x 24). Mr. Litrell stated that the low bidder makes the new signs, but, they are going to become uniform. Ms. DeRose suggested giving the bidders parameters on the signage to meet uniformity. Ms. DeRose asked to have a temporary COA so that the few streets that need street names on them now could be placed on "U" channels, temporarily. Mr. Oxian made a motion to have temporary approval to put up the street signs on the "U" channel and that a committee be formed to address all aspects of the blanket COA. Mr. Talley seconded the motion. The vote was unanimous. Mr. Oxian and Mr. Talley will be on the sign committee. Mr. Litrell asked for permission to speak on another subject. He.reported on the US 33 Michigan Street bridge over the river. The Indiana Department of Transportation does an annual survey and every six years an underwater survey for all bridges in its jurisdiction. 1994 report showed a bit of scour. 1996 report showed little or no difference so the Engineer was not concerned at this time to replace the bridge, but suggested the bridge possibly be placed on a replacement list in the next 15 years. Also, working with the Army Corps of Engineers on erosion control for protection of public facilities, Mr. • Litrell stated that Riverside from Vassar to Golden would be eligible and on Northshore from Iroquois to approximately 500 feet to the west downstream. Mr. Litrell continued to report on the condition of Ohio street. Mr. Litrell noted that both brick and concrete were covering Ohio street. He stated that the increased activity on the street does not match the condition of the pavement. He said that he could not afford to brick the whole thing. The curb on about half the sides (on both sides of the street) needs to be replaced. Where the brick and asphalt meet, the material looks to be raveled.
