The first public information meeting for this project was held on Tuesday, June 6, 2017, from 5:30-7:00 PM in the Johnston City Hall Council Chambers. The intent of this meeting was to start a dialogue with the surrounding property owners on issues from your perspective that may exist in the corridor.  The design team and representatives from the City were to be present to listen and gather your input so that it may be incorporated into the design process.

Project Update (as of 7/15/19)
The seeding and hydro-mulch has been placed. A decision has been made to temporarily not water due to the extreme heat even though no rain is expected. Reasons as to why are included below from correspondence from Pezzetti Erosion Control. Follow-up conversations after the below information included that if weeds establish at a high rate, mowing and/or herbicide will be discussed as an option to treat.

Given the fact that we completed seeding efforts during a marginal growing period it is in the best interest of the final establishment to allow seed to lay dormant for the next month. There are a couple of risks involved with the introduction of irrigation at this time.
  • Weed promotion, turf grasses do not germinate well during the weather conditions we have currently however, weeds do. Simply put, irrigating at this time will promote weed growth as well as promote desired species to grow at an unsatisfactory level. Turf grass germination levels can be reduced in this scenario by as much as 70%.
  • Irrigation in conjunction with a fragile seedling state, high UV index, and 85°+ daytime highs can significantly increase the risk of Pythium creation which is a form of fungus that can spread rapidly throughout the seeded areas and will essentially kill the seedlings.

Project Area

East of Merle Hay Road is the area between Merle Hay Road, Beaver Drive, Johnston Drive and NW 62nd Avenue. Here is a link to the Project Area Map. Neighborhood areas include NW 55th Avenue, NW 57th Avenue, NW 54th Court, NW 60th Avenue, & NW 61st Place. A map is available to identify which sub-group to which a neighborhood belongs.
Below are before and after pictures that have been prepared based on input from residents in the area during the above public workshops.

Visual Preference Survey

The visual preference survey was an exercise where the residents were asked to rate a series of images on a scale of -5 to +5 as to their opinion of how well a particular infrastructure improvement would fit in with their neighborhood. The improvements were grouped by category and the results are presented by neighborhood subarea average and the total neighborhood average. The most positive image in each category is highlighted in yellow, while the most negative image is highlighted in red. This purpose of the exercise was to begin the process of visualizing potential physical neighborhood improvements and to discuss the merit of various improvement alternatives. The results are not intended to be interpreted as definitive chosen alternatives.
