Mace Park 

Mace Park is a 3.2-acre park located on the south side of the north Channel of the Boise River at the southern terminus of the Eagle Road Ped/Bike Bridge.  The City received the property as a donation as part of the Mace River Ranch Development and is in the process of completing engineering and design work.  Below is a history of the project as well as the status of the preliminary engineering.

History of Mace Park

2011:

River Ranch Subdivision submitted to the City.  Requesting 255 units.  Due to anticipated traffic volumes ITD and ACHD required the development to take access from the signal at Island Woods Way and closure of Mace Road.  

2012:    

As part of the development review process the City of Eagle Park, Pathway and Recreation Commission requested the following improvements for the park:

  • Paved Parking
  • Drainage
  • ADA Parking and Curbing
  • Striping and signage
  • Improved access to SH-55 (Eagle Road)
  • Garbage containers
  • Pedestrian bridge over streams internal to the site
  • Additional considerations:   
    • Dog Off-leash area
    • Public Restrooms

2012/2013:  

Through the approval process for Mace River Ranch the City was offered 3.2-acres of park land for a Memorial Park including a shelter, restroom, parking (15 stalls), and greenbelt/ sportsman’s access.  The development agreement and approval documents retain the access point at Eagle Road SH-55 as an emergency services access point and park access contingent that the connection to residential properties/development is restricted.

2016/2017:

The City of Eagle through the park impact fee capital plan identifies the park as impact fee eligible for parking and greenbelt access.

2018:   

The City through the City Engineer (HECO) completes a survey of the site and begins preliminary design of the park including restrooms and parking (20-25 stalls).  Developed park land is restricted due to the floodplain and riparian areas on the site.

Spring 2021:     

City issue a request for proposals for the development of a park plan for the site, no responses are received.

 Winter 2021:    

City develops a scope of work with the City Engineer (HECO) to begin preliminary engineering for a parking lot (25-30 stalls)/greenbelt access at the southern terminus of the Eagle Road Ped/Bike Bridge being constructed in 2022-2023.  The scope of work was for preliminary design, environmental review/permitting, final design, and bid assistance. As of November of 2022, this contract is still in the preliminary design phase.  

HECO Scope of Work

  1. HECO Scope of Work

Summer 2022:

Preliminary meeting with ITD staff to clarify ITD standards and requirements for the site including acceleration/deceleration lanes, and possible median modifications.  Request modifications from ITD included:

  • The radii of the curb returns are indicated (R=15’ and R=30’). These radii meet/exceed the requirements of ITD Standard Drawing No. 405-1 using a T1 dimension of 20’.
  • Minimum width of the approach “throat” is approximately 25’ near the pathway crossing. We widened it from the 22’ width coming out of the parking lot by revising the south curb to allow for a wider section at the approach with Eagle Road.
  • It was requested that the stop sign be placed prior to the crosswalk. With the detached sidewalk, this would put the exiting vehicles approximately 25’ from the true stop location for vehicles entering on Eagle Road. We are proposing to eliminate the crosswalk markings and install a stop bar and stop sign at a location that provides the exiting vehicles with a better line of sight. This appears to be a similar method used on numerous approaches along Eagle Road where there are detached sidewalks. The stop sign and stop bar will meet MUTCD requirements.

Fall 2022:

Further refinement of the plan to address comments from ITD and begin outreach to Two Rivers HOA in preparation for community open house.  Site design includes 25 stalls including a new ADA ramp and improved pedestrian crossing at entry.
