Noise Wall Construction, Color, and Texture Meeting (Southern Section)

On Thursday, April 23, 2009, a noise wall construction, color, and texture meeting for the southern section of the project area was held at St. Helena Catholic School in Blue Bell, Pa. The purpose of this meeting was to give the owners of property adjacent to proposed noise walls in the southern section of the project area an opportunity to vote on whether or not they want the wall to be constructed and if so, the color and texture of the noise wall. The invited residents own property directly adjacent to and located closest to the physical noise wall structure.

Please click on the following links to view the displays that were available at the meeting, including the color and texture choices available for the noise walls, as well as links to sample renderings and noise wall mapping for the southern section of the project area.

Voting Results – Noise Wall Construction, Color, and Texture Meeting (Southern Section)
Fifty percent of the affected property owners in the southern section of the project area participated in the voting process. The questions and choices regarding the construction, texture, and color of the noise walls are listed below:

Question   Choices
Do you want a noise wall constructed?   Yes No
Which wall texture do you prefer?   Stone, Fuzzy Rake, Grape Stake, Shiplap, Brick
Which color do you prefer?   Gray, Tan, Brown, Beige, Red

The voting results are as follows:

Area 3 South (Blue Ballot) - I-476 South from Walton Road to Sheffield Drive:

  • Construction of the Noise Wall - Yes
  • Texture of the Noise Wall - Stone
  • Color of the Noise Wall - Tan

Area 3 North (Green Ballot) - I-476 South from Jolly Road/Meadow Drive to DeKalb Pike/Route 202:

  • Construction of the Noise Wall - Yes
  • Texture of the Noise Wall - Stone
  • Color of the Noise Wall - Gray

Area 4 (Yellow Ballot) - I-476 North from Buggywhip Circle to DeKalb Pike/Route 202:

  • Construction of the Noise Wall - Yes
  • Texture of the Noise Wall - Stone
  • Color of the Noise Wall - Brown

Area 5 (Pink Ballot) - I-476 North from Oakridge Drive to Crestline Drive:

  • Construction of the Noise Wall - Yes
  • Texture of the Noise Wall - Stone
  • Color of the Noise Wall - Tan

A meeting for the owners of property directly impacted by noise walls in the northern section (Upper Gwynedd and Towamencin Townships) of the project area will be held after the final plans display. The final plans display for the northern section is tentatively scheduled to be held later this year.

Noise Impact Analysis

This report describes the methodology and presents the findings of the traffic noise study conducted for the full-depth reconstruction project from Milepost A20 to A30 of the Pennsylvania Turnpike in Montgomery County, Pennsylvania. The full-depth reconstruction project will convert the existing four-lane roadway with a 10-foot median to a six-lane typical section with a 26-foot median. The purpose of the traffic noise study is (1) to determine if project-related noise impacts will occur and (2) to determine whether noise abatement for affected areas in the form of noise barriers or other mitigation measures would be warranted, feasible, and reasonable, based upon Federal Highway Administration (FHWA) and Pennsylvania Department of Transportation (PennDOT) criteria as utilized by the Pennsylvania Turnpike Commission.

Noise Impact Analysis
The Noise Impact Analysis Report is a very large file (approximately 20MB). Depending on your internet connection, downloading time may vary.

Noise Mitigation Mapping

This stand alone mapping graphically conveys the results of the Noise Impact Analysis Report for the total reconstruction and widening of the Northeastern Extension (I-476) from the Mid-County Interchange to the Lansdale Interchange. The full report, dated May 2008, is also available in digital format on this project web site.

These maps provide a graphic representation of the project area with a focus on noise-sensitive features of the design and the existing landscape. Noise Sensitive Areas (NSAs) have been identified on the mapping, and are used as an organizational and analytical tool to identify communities experiencing common traffic noise influences. Additionally, both monitored and modeled sites used in the analysis are graphically depicted on the aerial mapping, as is the proposed edge of shoulder for the improved facility. Noise barriers that are recommended for construction are represented on the mapping by a "dashed" black and yellow line.

Noise Analysis Workshop

On October 17, 2007, Senator Rob Wonderling and Towamencin Township hosted a traffic noise analysis workshop for Towamencin residents. This workshop, presented by the Turnpike's Northeastern Extension project team member Nathaniel Weinstock, Acoustic and Air Quality Specialist with A.D. Marble & Company, provided a detailed review of traffic noise analysis methodology used on highway projects in Pennsylvania.

The following guidelines are utilized by the Pennsylvania Turnpike Commission for traffic noise analyses and are sometimes referenced in response to inquiries about noise walls.
