Brief Lane Closures on D Avenue: Sept. 11 – Sept. 22

Starting on September 11, neighbors may notice a crew in the project area with an auger truck. The crew will be collecting some additional information on the soil and its ability to infiltrate water. For your safety, there may be some brief lane closures during work hours: 7 a.m. – 6 p.m., Monday to Friday. Please watch for signage or flaggers during these times. The work will be intermittent for about two weeks.

Design Team Balancing Details of the Meandering Road Alignment

City staff and design consultants have been working on designs for the stormwater, pavement, and pedestrian improvements on D Avenue from State Street to 10th Street. We are using feedback we heard from neighbors during last winter’s walking tours and the open house in May, as well as survey and soil data. We are now meeting with some neighbors along D Avenue who we have not yet heard from, or where we have questions.

At the open house in May, neighbors gave feedback on two road alignment concepts: a straight road or one with slight meandering curves. Of the two road alignment concepts, a majority of participants at the open house expressed a preference for the meandering road alignment. Many liked the aesthetic opportunities, flexibility for landscaping and parking locations, preservation of significant trees and potential to slow traffic through design. There were still several neighbors who preferred a straight alignment concept that they felt was consistent with original First Addition development pattern.

Given all the technical information and community input, the City is moving forward with designs for the meandering alignment and working to balance stormwater management, pedestrian needs, neighbor desires, and what we’ve heard about the character of the street.

In late October, we expect to have 60% level designs to share with the community at an open house. More information about that meeting will be announced soon.

We appreciate everyone’s participation and look forward to seeing you in October.

First Open House a Success!

On Thursday, May 11, the City and project team held the first public Open House for the project. More than 75 people attended the event, providing great feedback and input.

Thank you to everyone who attended! We appreciate your participation in the project, and for sharing your thoughts and ideas about the initial design concepts proposed for D Avenue. Your early input on the concepts for the street alignment, sidewalk and stormwater facilities will help the team move forward with design of a preferred option.

A meeting summary is available here. If you were unable to attend the open house, the displays and concepts presented are available on the materials page of the website. Please note, these are not final designs – these are preliminary concepts only.

The project team is now compiling and collating all the feedback received to date and will begin preparing an alternatives analysis, which will guide the project into 30% design. Part of this analysis will outline which is the preferred option and why, along with addressing the concerns and challenges people have raised.

The team plans to hold a second Open House later this summer – to present the preferred option and 30% design drawings, and seek additional feedback to refine the design.

For more information, please contact the project team.

Open House: Thursday, May 11

Great Participation During Recent D Avenue Neighbor Walking Tours

In late January and mid-February, the project team held two D Avenue walking tours for neighbors located along D Avenue, between 10th and State Street. Thirty neighbors participated in the tours. The walking tours provided an opportunity for the project team to meet with, and learn from neighbors adjacent to D Avenue, prior to beginning design work.

THANK YOU to all neighbors who attended the walking tours – we appreciate your willingness to participate and to share your thoughts, concerns and ideas on the improvements for D Avenue. Your early input and ideas will help the project team incorporate these into the first stage of design.

A summary of the walking tours, including key themes that were raised or discussed by participants, is posted on our materials page.

Several small group meetings and follow-up visits with select property owners will occur in the coming weeks.

Preliminary design concepts will be developed over the next few months. Once these are developed, the project team will host an open house (likely this spring), inviting all members of the community to view and comment on the plans.

Final design plans are anticipated to be complete in the fall of 2017.

Update on preliminary work:

  • Groundwater monitors have been placed, and are currently collecting data for the design team to incorporate and consider during the next few months
  • Geotechnical drilling for soil samples has occurred
  • Surveyors have been on-site performing boundary and topography mapping

Tree survey starting soon!  

During the next few weeks, neighbors may notice surveyors flagging trees located along D Avenue (in the 60 ft. right-of-way) and in the project area. The project team will be looking at how to minimize any impact to trees. A certified arborist will be surveying the health and condition of the trees.

For more information, please contact the project team.

Additional Half-Day Road Closures on D Avenue – January 5

Due to inclement weather in December, crews will return tomorrow, Thursday, January 5, to conduct exploratory digging and collect soil samples on D Avenue. This work will require temporary, half-day road closures along D Avenue, between State Street and 10th Street. Closures will occur one block at a time, between 8 a.m. and 5 p.m. Residents located within the closure area have been issued door hangers.

Local access will be maintained at all times for residents and businesses located within the closure. All deliveries, garbage collection and mail services will be maintained. Please watch for signage or flaggers.

For more information, please contact the project team.

Surveyors and Crews Begin Preliminary Work on D Ave

Beginning in November, surveyors and crews will begin preliminary field work, collecting information in the D Avenue area. Neighbors in the FAN neighborhood may see crews taking photos, surveying the area for elevation and locations of underground utilities, mapping and assessing the health of trees, installing groundwater monitors, and gathering other information to inform the design work and future construction. Crews will not be out the week of Thanksgiving.

You may notice the following:

  • A few half day road closures will occur on D Avenue one block at a time, while crews install groundwater monitors, collect soil samples and conduct exploratory digging; flaggers or signage will direct drivers around the block or assist local neighbors with access.
  • Trees may be flagged during survey work. We will be looking at how to minimize any impact to trees and will have an arborist working with the team.
  • Underground utilities will be marked with paint on the street, shoulder or in the grass in the public right-of-way. Marks will disappear overtime, but these are necessary to complete our survey for use in design and later construction.
  • Wooden stakes with flags will be left at some places along the project area. These may indicate public right-of-way, property lines, drainage issues or other considerations. Please don’t remove the stakes.

If you have any questions, please contact the project team.
