.' q LAKE ELMO CITY COUNCIL MINUTES SEPTEMBER 4, 1990 PAGE 2 M/S/P Armstrong/Hunt - to approve a shoreland permit to William Park, 4589 Birch Bark Trail, to construct a 4-season porch (18' x 16') over an existing patio area based on the fact no variances are needed and DNR has given their approval. (Motion carried 5-0). 7. CITY ENGINEER'S REPORT: A. Speed Complaint on 24th Street At the August 7th meeting, the Council received some complaints of excessive speed on 24th Street between Lake Elmo Avenue and Legion Avenue, particularly in the vicinity of 24th Street Court. Some residents suggested a 3-way stop at that intersection. This matter was referred to the Engineer for his review and recommendation. The Council acknowledged a 1eM r from Kendre Schwabel, 11365 24th St. Court, stating her concerns on speed of vehicles using 24th Street and requesting placement of proper signage to slow traffic down. City Engineer, Larry Bohrer reported on August 30th a drive -over inspection at varying speeds was made with the Maintenance Foreman. The following observations were made: 1. The street has three horizontal curves (two west of 24th St. Ct. and one east) which have a 200' centerline radius. These curves feel uncomfortable to the average driver at speeds over 30 mph due to outward centrifugal force. 2. The sight distance from 24th St. Court intersection is good looking either east or west along 24th Street. 3. The traffic counts are low and will remain so because the road only serves Packard Park and a portion of Eden Park. 4. Stop signs should not be erected at the intersection because the traffic does not warrant it and stop signs should not be used for speed control. Based on these observations, the Engineer and Maintenance Foreman made the following recommendations: 1. Place a YIELD sign on 24th Street Court at 24th Street to show that the cul-de-sac traffic must yield right-of-way to the through street. 2. For eastbound traffic, a Reverse Turn Sign (W1-4R) with a 25 mph Advisory Speed Plate (W13-1) should be used. The City on its own initiative cannot post speed limits lower than 30 mph except for advisory speed on curves. 3. For westbound traffic, a Left Turn Sign (WI-2L) with a 25 mph Advisory Speed Plate (W13-1) should be used. 4. After the curves, 30 mph speed limit signs could be used.
