Traffic Control Analysis Report (Pine Glen, Pinehill, Meadow Acres and DeGardners Additions) City Engineer Jennifer Levitt distributed maps to accompany the report. The area first discussed is located south of 90th Street, north of 100th, encompassing Hadley to the west and the Industrial Park to the east. Residents in the area have requested traffic control changes related to stop signs. If one intersection is changed, there would be inconsistency throughout the neighborhood. Residents were informed that City staff preferred to address the change as an entire neighborhood analysis rather than looking at specific intersections. The City Sign Policy has been included in the packet to try and make more consistency with the City on signing. As indicated in the “Stop Sign” section of the policy, local to local intersections are specifically addressed. Levitt noted this issue was dealt with in the 2008 Pavement Management Project. Non-local roads include 95th Street, Hadley Avenue and 100th Street (collectors). Anything within the interior of those roadways is considered local to local. The study area is residential with private driveways on all local streets. The two private roadways of Hamlet Lane and Hamlet Court have multi-family residential housing. On the east side of Hamlet Avenue from 100th Street to 120 feet north of 98th Street to Pine Glen Park is a bituminous trail. Two short stub bituminous trails exit to Pine Glen Park: Hamlet Avenue (next to Hallmark Avenue) and 97th Street (between Hames Avenue and Hames Court). Parking is allowed along all local roads in the study area. All local roads are two lane, unstriped roadways. All collector roads surrounding the study area are striped, 2 to 4-lane roadways. RECOMMENDATIONS: T-Intersections: State law dictates that traffic on the “T” approach leg shall yield to traffic on the through leg. T-Intersections with local to local roadways will be uncontrolled. Due to higher volume on collector roadways, it’s desirable for traffic on the “T" approach to stop at these intersections. Stop signs will be installed at the “T” approach at all T intersections on collector roadways. All 4-leg intersections will have a stop sign on the minor street. Warning Signs The other issue in this area dealt with the warning signs (“Curve Ahead” signs with a speed placket of 10mph). The Sign Policy indicates the overuse of warning signs, specifically on low volume streets. Warning signs shall be used only where special conditions exist. Warning signs will be installed on collectors to warn of unexpected conditions. Warning signs will be installed on local roads to warn of conditions not typically encountered on a low speed residential street. Speed Limit The statutory speed limit on residential roads is 30 mph. Speed limit signing is not normally needed on these roadways. Speed limit signing will be installed on local residential roadways if the speed limit is other than 30 mph or where the 30 mph is not apparent. On collector roadways, speed limit signs will be located after major intersections, at the locations of speed limit changes and at other locations as determined by the engineering study. Crosswalks Levitt stated there were some mid-block pedestrian crossings that were not marked and that is where the policy comes into place. City policy states that all mid-block crosswalks be marked and crosswalk signs be installed. If the speed limit is over 30 mph, or if there are sight restrictions approaching a crosswalk, advance crosswalk signs will be installed. Stop Signs Levitt indicated there are some four-legged intersections that don’t have stop signs. It is proposed to add stop signs to stop Hale Avenue in the north/south direction at 94th. On Hallmark Avenue it’s proposed to stop in the north/south direction and allow 94th Street to flow into the neighborhood. Commission Chair Ken Boyden inquired whether there are any traffic accident reports from Public Safety regarding the areas where stop signs are proposed to be removed. Levitt responded she can ask the Police Department about accidents in these areas and try to find the installation year of the stop signs in those locations. RECOMMENDATONS: There are locations where stop signs are located on the “T’ legs of local-local intersections. There were no observed sight restrictions at these locations. The stop signs should be REMOVED at the following locations: (Local-Local Roadways) Heath Avenue at 99th Street Heath Avenue at 98th Street Heath Avenue at 97th Street 97th Street at Hamlet Avenue Hames Avenue at Hamlet Avenue 94th Street at Hamlet Avenue Hamlet Avenue at Harkness Avenue REMOVE stop signs at following intersections) (Existing 4-leg intersections – stop control on the minor street) Harrow Avenue at 97th Street 98th Street at Hayward Avenue There are yellow curve warning signs located in the project area. None of these conditions are excessively dangerous nor unexpected in a residential area. Additionally, these signs are not consistent with looking at the area as a whole. It is recommended the following warning signs be REMOVED: (warning signs will only be installed to warn of conditions not typically encountered on a low speed residential street): Yellow left turn (arrow) sign with 10 mph advisory plaques on Lower 94th Street and Hale Avenue Yellow left turn (arrow) sign with 10 mph advisory plaques on Lower 94th Street and Hallmark Avenue Yellow left and right turn (arrow) signs with 10 mph advisory plaques on Hames Avenue It is proposed to INSTALL stop signs at the following locations: (stop control on minor street) 98th Street Courts (north and south) at 98th Street Hayward Avenue and Hayward Court at 98th Street Hale Avenue (north and south) at 94th Street Hallmark Avenue (north and south) at 94th Street It was noted that on Hamlet Avenue we encounter a trail crossing that enters the roadway. Right now we do not have mid-block notification for motorists that pedestrians may be entering the roadway. It is proposed to add the pedestrian crossing signs there to alert them to that. It is proposed these pedestrian crossing signs be INSTALLED at the following locations: Hamlet Avenue and Hallmark Avenue 97th Street and Hames Avenue Hamlet Avenue at 98th Street A “No –Outlet sign may be added at the following intersection (if requested by residents): 97th Street and Hames Court Levitt said it’s anticipated that residents will be notified of the changes and invited to attend the next meeting in order to address the committee with their concerns and issues before the final recommendation is made to Council. Every resident living in the project area will receive a notice of this meeting. A website address will provide information, including the policy and procedures for sign placement. Area residents will have the opportunity to attend the Public Works Commission meeting on March 8th. Commission members will listen to their testimony and comments and then provide a recommendation to the City Council at the March 17, 2010 meeting.
