COMMUNITY FEEDBACK FROM WARD 6 Date: Friday, 19 October 2018 Time: 4:30pm - 5:45pm Location: Ward 6 Offices, Tucson, AZ
Q1, Project Design: Since we are attempting wildlife habitat restoration, are there other things we could be doing to encourage better/more flora and fauna on the site? A: There is a huge concern that has been brought up in past community meetings about how while encouraging birding is great, it draws predators to the area. People feel extremely strongly about keeping predators away, but the majority are extremely happy to hear about potential for more birds on the site. Q2, User Groups: Are there other programs the surrounding users of Highland (Target Employees, neighborhood residents, bird watchers) would like to see in this design? (community meeting space, running track, other bird watching opportunities?) A: Prop 407 will give a list of amenities in the parks that were specifically requested by the communities. It would be wise to not remove these amenities now. Q3, Policy/Cost/Etc.: Are there policies that require certain lighting on the park sites for public safety? A: Check the Prop 407 website for lighting safety requirements in the area.
CONCLUSION
1. The community is very happy about talk of urban wildlife, but concerned with the potential to bring more predators, especially coyotes, into the area.
2. The Prop 407 website is a valuable asset for finding information on the amenities that are either currently on the sites or are desired by the users of the sites. Highland Vista Park, for example, has a walking path that is maintained in the design due to its communal value.
3. If an amenity is on the site already, it is best to either preserve or enhance it in some way. DO NOT remove.
AUDUBON SOCIETY INTERVIEW Date: Wednesday, 7 November 2018 Time: 2:30pm - 4:30pm Location: CAPLA, Tucson, AZ
Q1: Do birds have a typical migration pattern along the wash? \\ Do you have a bird migration map for Tucson? A: Birds are attracted to running water and lush vegetation. Different species will be attracted to different vegetation. For a variety, it is important to have a mixture of different plants for habitats. Q2: We’ve had community concern raised about the attraction of birds meaning attraction of predators in the area, especially coyotes. What are some deterrents that we could implement into our designs to keep these predators away? A: Dense vegetation and tall grass make it easier for coyotes to thrive. You could trade off having less birds attracted to dense brush in exchange for less predators attracted to the area, and you’d still have a decent mixture of bird species. Q3: What are the most important components of a bird watching habitat? \\ What is most important for ensuring bird comfort? A: Nothing beats natural, native vegetation to feed the birds of your area. As mentioned before, a variety of native plants is most important to ensure multiple species have places they are comfortable, as well as running water, which the wash will ensure. Ponds and water gardens help as well, which you seem to have designed for your site. Q4: Does bird migration impact a habitat design differently than a habitat designed for long term habitation? A: Birds will remain in your habitat during the breeding season and longer term if they have places to nest and raise young. Of course, different species have different requirements. Some nest in cavities, and others prefer open nests in tree crotches. Some even prefer to nest on the ground. Q5: We have multiple uses on the site, including louder human activities such as sports games. Is there a noise buffer distance we should be keeping in mind to ensure the birds are not scared away? A: Quiet time for most species is not necessary. If the birds have enough vegetation and density that they consider a safe shelter, they ought to be fine. Depending on the species, anywhere from ten to fifty feet can be required. Since Highland’s bird watching area is separated from the rest of the park and it has a bird blind, this is more than enough.

OFF-LINE DETENTION BASIN
The western portion of the site will be used as the biggest intervention in floodwater mitigation, as it takes water directly from the wash during flooding and stores it temporarily in the form of off-line detention, allowing some of the water to infiltrate, and the rest to return to the wash after the floodwater has left the wash.
RAINWATER BASIN
The field basin can be used year-round as a recreational open space. The walking path that runs around the site as suggested in Prop 407 is maintained around the outside. The basins capture rainwater and water runoff from the surrounding neighborhoods. An underground pipe allows water to be redistributed into the wash at a slower rate to keep the basins from having more than nine inches of standing water at a time.
EXISTING WATER HARVESTING PROJECT
The southernmost portion of the sites already has an existing project, which will be left the same. There are boomerang berms, infiltration basins with check dams, and micro-catchment basins that will aid in controlling any water overflow from the field basin.

BIRD WATCHING OPPORTUNITIES
The western portion of the site will benefit from the addition of a bird watching blind and more vegetation. The running water from the detention basin itself will attract more urban wildlife, providing ample habitat space for local birds. The bird blind will allow visitors to observe the birds without disturbing them.
RECREATIONAL STRUCTURES
The field basin will benefit from the addition of shade structures that present unique opportunities for playing in the rainwater. When it is not raining, the structures will provide space on site for multiple events, including watching sports games in the center basin as well as tables and chairs where other events may take place, such as birthday parties or community meetings.
MORE AMENITIES
The entirety of the site will gain value with the implementation of more amenities. On top of the running track, there will be bridges added over the wash to allow for better circultaion throughout the site. There will also be multiple areas with tables and chairs where employees from the local Target may go to enjoy their lunch break. There will also be much more vegetation, creating a cooler, more beautiful site tha the community can take pride in.
VOLUMETRIC STORAGE COMPARISON
In order to fill the basins on the site, which is 391,021 gallons, you’d need approximately 775 pickup truck beds worth of water.
*each truck bed holds 505 gallons
