REPORT TITLE: Windrose Multiway

REPORT NUMBER: 2017-CoW-038

REPORT SUMMARY Administration has completed detailed design for the Windrose Multiway and providing Committee with an update on the various options and design details.

BACKGROUND PREVIOUS COUNCIL/COMMITTEE ACTION:

• 2016-CoW-001 Windrose Multiway Extension — Options were provided for Committee consideration. The report also identified that the Parks, Recreation and Culture Board had recommended alignment of the multiway within the boundaries of the Public Utility Lot (PUL) in a manner that would minimize the number of trees being removed.

• 2016-CoW-060 Windrose Multiway Extension (Supplementary Report) • Committee-of-the-Whole Council Meeting — Budget Deliberations— November 17-19, 2016 - Committee members

were in agreement to have the funds required for the Windrose Multiway extension moved into the 2017 budget. The exact location of the extension is still to be determined, however, it will be the boundaries of the PUL.

KEY ISSUES:

The proposed Windrose Multiway Extension is to provide a connection for the Multiway that is parallel to Black Gold Drive to the future Black Stone Development through an extension on the East side of the section. When the initial Windrose Neighbourhood Area Structure plan (ASP) was completed the ASP identified in section 3.2.3 Parks, Open Space and Walkways that as part of the multiway trail system, the "multiway may occupy... the pipeline easement, which runs along the east side of the site adjacent to the golf course."

During November, 2014, the City conducted an open house for Windrose residents located on the East portion of the community. At that time, administration obtained approval from 35 residents for email updates. Email updates were sent to those individuals on the following dates providing updates on decisions and directions related to the project on:

• November 21, 2016 — notifying residents of the rescheduling of the project, no responses were received at this time • April 21, 2017— initial design options that were reviewed by administration

Administration has received the detailed drawings from the consultants for the proposed Windrose Multiway connection from Black Gold Drive to the future Black Stone community. Upon completing site visits and detailed review of the site, the consultant has proposed three options:

Leduc

Option 1 — Straight Option — Estimated budget of $530,605.33 • 3.0M Asphalt Multiway with option to reduce 2.5M, adjacent to the existing tree line with 1.0m buffer on both sides

for maintenance. • Multiway would be approximately 1.0M away from property line. • Minimal impact on the existing natural environment.

O Tree line would remain the same on the Northern section O Small portion of tree line would be removed on the Southern section to accommodate multiway O Limited tree removal would continue to allow for privacy from the golf course.

• Estimate does not include replanting of shrubs or trees as per comment below.

Option 2 — Straight Option — north phase only to the PUL at Westlin Drive — Estimated budget of $300,000 based off Option 1 cost estimate

• 3.0M Asphalt Multiway with option to reduce to 2.5M, adjacent to the existing tree line with 1.0m buffer on both sides for maintenance.

• Minimal impact on the existing natural environment. o Tree line would remain the same on the Northern section o Small portion of tree line would be removed on the Southern section to accommodate multiway o Limited tree removal would continue to allow for privacy from the golf course.

• Estimate does not include replanting of shrubs or trees as per comment below.

Option 3 — Meandering Option — Estimated budget of $726,830.33 • 3.0 Asphalt Multiway, meandering throughout the entire length with 1.0m buffer on both sides for maintenance. • Increased impact on the existing natural environment.

o This option would increase the amount of the existing tree stand that needs to be removed to accommodate the require buffer for maintenance.

• Increased cost due to excavation to subgrade and preparing site for proper drainage. • Estimate does not include replanting of shrubs or trees as per comment below.

For all options, the proposed area has minimal slope to work with to drain water away from the multiway without shedding water into the golf course or the back of resident lots. The best way to achieve drainage through the area is by moving the water the shortest distance which is a straight line. The meandering option would increase the distance needed to drain water making an ideal situation worse and increase in higher maintenance costs and a lower overall life cycle of the multiway.

In addition, Administration had previously proposed additional plantings and shrubs to mitigate impact on residents and provide additional security and privacy. However, current discussions with AltaGas Ltd. have identified a zero planting policy in their right of ways which includes small shrubs of any type. At this point, the City has not received approval to plant between the trail and the property lines as initially planned. AltaGas Ltd. also identified that they regularly brush clear their right of ways with the next planned clearing for 2020, meaning that any plantings that have not been preapproved would be cleared by regularly scheduled brushings. Other mitigation options could include allowances for privacy slats in private fences or privacy fence within residential lots.

Administration has identified Option 1 or Option 2— Straight Option as the recommended option with the following changes to be considered:

• Reducing the multiway to 2.5M, which will increase the distance of the multiway from 1.0M to 1.5M from the property line.

• Providing residents that directly back onto the proposed multiway a planting allowance for their property as planting is not currently allowed within the right of way.

• Continue discussions with AltaGas Ltd. at a later date for proposed plantings.

' Leduc

An information session can be held on Thursday, May 25, 2017 for all residents of Windrose. This information session can be organized to provide an opportunity to inform the residents on the details pertaining to the project, or to provide an opportunity to gather further input from the residents on the details pertaining to the project. For either option, administration will send out a postcard invitation to all residents within Windrose.

At this time, Administration is prepared to construct Option 1 or Option 2. The current budget for the Windrose Multiway (076.306) is $400,000. For the full length of the project to proceed and/or to provide an additional contingency for privacy mitigation, additional funding could be reallocated out of the existing general multiway budget. These cost estimates are based on optimal tender pricing which would need to be completed by the end of May.

It is important to note that the developer who will construct the multiway connection at the south end of the PUL (38th avenue) as outlined in the Black Stone subdivision application has requested a deferral of this connection to a future stage.
