MEMORANDUM

To: Mayor and City Council

From: Michael Smith, Public Works Director

Date: 4/11/2011

Subject: Discussion of 2011 Capital Paving Project

ITEM DESCRIPTION

Approve list of streets for 2011 capital paving.BACKGROUNDThe City has budgeted $1,800,000 for paving in the 2011 budget. Additionally,

$200,000 of state funding through the Local Maintenance and Infrastructure Grant

(LMIG) is anticipated. The recommended 2011 project list in Attachment I has

been developed based on a total paving budget of $2,000,000 and follows the

recommendations of the 5-year paving plan.

BICYCLE ACCOMODATION

Roberts Drive is the only street on the 2011 project list that is designated for abicycle facility in the Citys transportation plan. Most of the other main

thoroughfares in the project list are recommended for bike routes meaning signageand sharrow pavement markings. At Councils direction, Public Works hasconsidered the feasibility of adding on-street bike lanes as part of the pavingproject for all streets designated for bike facilities or routes. A field review of theconditions on each street indicates that the segments of North Shallowford, NorthPeachtree and Peachford proposed for paving can accommodate bike lanes throughrestriping with 10-foot travel lanes.

Bike lanes could also be added to Roberts Drive through restriping betweenChamblee Dunwoody and Austin Elementary School. North of Austin there areseveral segments where the existing pavement narrows. Between Aurora Lane andManning Farm Court there is no curb on one side and there is enough room on theshoulder to add pavement for a bike lane. I estimate that this would add about10% to the total cost of paving for Roberts Drive and would allow the bike lanes tobe extended to Mill Glen.

On Peeler the existing pavement between Independence Square and HuntingtonHall is wide enough to accommodate bike lanes through restriping. BetweenHuntington Hall and Adams Road the road narrows and pavement would need to beadded on the south side of the road to accommodate bike lanes. I estimate that thiswould add about 20% to the total cost for paving on Peeler Road.

Most of Tilly Mill Road between the City Limits and Peeler has curb on both sides ofthe road and is too narrow for on street bike lanes. Public Works has estimated theadditional cost to move curb, drainage and sidewalk to add pavement for bike laneswill range from 2.5 to 4 times the cost of the resurfacing alone.

RECOMMENDED ACTION

I recommend approval of the 2011 project list shown in Attachment I. To work

towards the Citys goal of becoming more bicycle friendly, I recommend narrowinglane striping where feasible; continuing to seek additional outside capital fundingsources for bicycle infrastructure; incorporating bicycle accommodations into newroad construction projects; and installing the signage and sharrows on the bikeroutes recommended in the transportation plan where it is cost prohibitive to widenthe road for bike lanes. Upon approval, Public Works will begin preparing moredetailed construction estimates and bid documents for paving.
