Recommended Action: MOVE to approve the Granite Creek Corridor Master Plan




In 2018, discussions began among interested citizens, business, and staff regarding the use, safety, appeal, and water/riparian quality and health of the Granite Creek Corridor. It was determined the best step would be to create a comprehensive plan with scientific data and public input. Grant funding was received planning began in late 2018 with funding from the Arizona Water Protection Fund in the amount of $79,401. Three public meetings were held and a public survey was distributed resulting in over 600 responses, which were taken into account as part of the findings and recommendations.


Item Summary


This item is for the approval of the Granite Creek Corridor Master Plan. This plan summarizes the findings, recommendations, and items for consideration as the City moves forward towards implementation.


Financial Impact


The Master Plan itself was paid for by grant money and the approval of the plan does not create an obligation to fund any portion of the recommendations. However, overall costs to implement all recommendations are estimated at $1,755,143. To accomplish this in phases, staff will be seeking grant funding, which will be brought back to the Council for approval before pursuing.

Mayor Pro Tem Orr commented that she appreciates the work that has gone into this and sees how much progress has already been made. This is an asset that has not been tapped by the community, will be safer and more beautiful and ties in with the Hilton Garden Inn. She feels we need to put our full effort in this.

Mr. Goodman commented that the next cleanup date will be April 18th.

Councilmember Rusing stated that she has always considered the area a hidden gem and it will be anchored by the Hilton Garden Inn and should be included in our Tourism Marketing when it is completed.

Councilman Sischka asked what the feedback has been from businesses along the corridor and if they may have plans for expansion to tie in with all of this.

He expressed the need to phase the various aspects of the projects to keep funding in mind.

Recreation Services Director Joe Baynes discussed the walk through with State Parks that took place a few weeks ago and commented that there are a great deal of grant funds available which staff will pursue and likely receive some of.
