Good morning and thank you for your patience while I worked with the project team to get you the requested details. Below are the answers to the bullet point you shared with me  via text.  Anything in italics is city’s response

1.       Stop the cement pour and use boulders or something natural for the preserve. I do not think painting is an option because after 2 years it will be cement. Concrete channel lining is proposed only in limited sections of the drainage channel where engineering analysis determined it is necessary to safely convey stormwater flows with high velocity and to reduce the risk of erosion and long-term maintenance issues. In areas where flow conditions allow, the design incorporates the more natural treatments, including angular rock riprap, native rock materials, and desert-compatible stabilization features intended to better blend with the surrounding environment. The project team understands and appreciates resident concerns regarding aesthetics and preservation of the desert character in the Phoenix Mountain Preserve. For that reason, the design was developed to minimize disturbance where feasible while still meeting required public safety and drainage performance standards. Additional measures, including the use of native materials along berms and drainage features, are also intended to help the completed improvements integrate more naturally into the existing desert setting.

2.       Replant vegetation; do not just spray seed. Can we get an exact number of trees, cacti, or shrubs to make it right. Due to the project being on the side of a mountain and doesn’t have irrigation, the project team will not be planting any trees or shrubs. The team planted and salvaged 28 cacti in total during the first round of construction, and they have been protected in place and the team is looking into adding a few more at this time.  

3.       Cover all loose dirt. During the construction, the Contractor will use dust mitigation measures. The revised plans have us line the channel, use rip rap and seed the disturbed areas to mitigate dust.

4.       Not becoming a new trail like it did this weekend. Per City of Phoenix Parks Department, the 24th street is not a public entrance to the preserve.

5.       How will this passage be maintained and cannot be used for recreational purposes. The city and its internal departments are discussing the best approach to this, possibly to install some kind of ‘edge protection’
