8.2. SR 05-21-2012REQUEST FOR ACTION TO ITEM NUMBER -Mayor and City Council 8.2 AGENDA SECTION MEETING DATE PREPARED BY General Business May 21, 2012 Jeremy Barnhart, Planning Manager ITEM DESCRIPTION REVIEWED By Orono Parkway Boulevard Design Cal Portner, City Administrator REVIEWED BY ACTION REQUESTED Staff recommends improving Orono Parkway in a manner consistent with Option 2 using the following process: 1. Mow the visibility sections when visibility is affected (late June/ July). The following steps would take place as budget allows: 2. Plant trees in the prescribed pattern in the non - visibility areas late summer /fall. 3. Add boulders and lower planting options in the visibility sections late summer /fall. BACKGROUND /DISCUSSION On March 12, staff presented preliminary designs of the Orono Parkway for the Council's review. With Council direction, staff has been working with HKGI on the refinement of the plans and the cost estimates. Based on these discussions, staff has prepared five options for Council discussion. While these options were prepared with Orono Parkway in mind, the improvement of the other boulevards (Twin Lakes Road and 193'` can be independent of the decisions made for Orono Parkway. In fact, it is recommended that they would be, as Orono Parkway provides some unique challenges. In the development of these plans, staff's primary goal has been to improve the streetscape appearance of this section of Elk River, address intersection visibility concerns raised by the Police Department and other parties, and introduce maximum improvement with as little costs as possible, all without imposing a great deal of additional work on Parks and Street Department staff. Some of the main issues driving staff's recommendation: Irrigation. Understanding the Council's aesthetic concern with the prairie type plantings, it is apparent that the introduction of turf grass will require an irrigation system. While staff understands there was irrigation in the median in the past, all connections to this system were removed when the berms were removed. Of the $40,000 irrigation estimate, $35,000 is the landscape architects estimate of the system and $5,000 for the water access charge (WAC) and other incidental plumbing costs associated with creating a new service near the Fresno Street alignment. Recall that there is over 2,000 linear feet of P0ME8E0 8i N: \Public Bodies \City Council \Council RCA \Agenda Packet \05 -21- 2012 \SR to CC boulevards 5- 21- 12.docx INATUNNIf El median on Orono. In formulating staff s recommendation, it is our belief that the aesthetic concern did not outweigh the expense of the irrigation system. Visibili1y. One of the original drivers of this project has been the need to address visibility issues caused by the height of the prairie plantings at the median breaks. In the last couple of years, smaller plants were introduced. While that addressed the problem at some level, it became apparent that the visibility concern was due to a longer section of the medians not improved with the plants. In developing a recommendation, staff felt this was vital to the success of this project, one that needed to be addressed completely. Maintenance expectations. One of the draws of the current prairie planting configuration is the limited maintenance necessary. Improvements to the boulevard will require additional maintenance, including hand watering the tree installation until establishment (plans with no irrigation), mowing (plans with turf grass), and weeding (plans with mulch areas). These costs will be estimated as hours, and could be handled by Parks and Recreation staff or contracted with bids. Option 1. Leave the prairie planted median as is. The "do nothing" plan. The median would be mowed after the bloom period (late July) and left as it currently sits until new growth in the spring. Analysis: The least expensive of the options. This does not address the beautification and visibility issues raised. Option 2. Add over story and ornamental trees, remove the prairie grasses where they obstruct vision (replace with softball to head sized boulders and lower growing grasses) even with the curb, and retain remaining prairie grasses. Retain recently planted ornamental plants as much as possible. The boulders are available at the Public Works Facility. Analysis: staffs recommendation — addresses beautification, visibility, cost, and maintenance goals. Option 3. Add overstory and ornamental trees, leave prairie grass in center, and replace outside areas with turf grass. Analysis: Requires irrigation, costly, but meets the beautification, visibility, and maintenance goals, although weekly mowing would be required. Option 4. Add overstory and ornamental trees, place rock mulch in center, and replace outside areas with turf grass. Analysis: Requires irrigation, costly, but meets the beautification, visibility, and maintenance goals, although weekly mowing would be required. Frequent weeding of mulch areas will be necessary. Option 5. Add overstory and ornamental trees, place wood mulch in center, and replace outside areas with turf grass. Analysis: Requires irrigation, costly, but meets the beautification, visibility, and maintenance goals, although weekly mowing would be required. Frequent weeding of mulch areas will be necessary.
