Introduction
HILLOWAY PARK RENEWAL MASTERPLAN17 December 2002
The proposed concept plan for Hilloway Park capitalizes on the assets of the park’s natural and cultural history, which lend itself to creating a master plan that mirrors the biomes found in Minnesota:
• Pine: Northern Coniferous Forest in the northeast
•Hardwoods: Deciduous Forest from the northwest to the southeast corners
•Prairie: Prairie Potholes in the southwest corner

To minimize trail erosion and further mimic the Mississippi River, the trail at Hilloway Park will also widen toward the park’s south end just as the Mississippi River widens from north to south as it carries more and more water.
Just as the Mississippi River travels through Minnesota’s 3 biomes in a north-south direction, the path through Hilloway Park leads park visitors through the 3 biomes at Hilloway Park.

Park entrance: see sketch
Existing trail: - Re-surface gravel portion with pervious pavement or soil cement to reduce erosion of gravelPine - Hardwood transition interpretation: see sketch
Raise outlet elevation of wetland to restore hydrology
Gathering space: council ring - Informal seating and picnicking provisions
Slope stabilization along stormwater utility
Hardwood - Prairie transition: see sketch
Potential designated trail connection to Byrnes Rd. to be positioned along
existing deer track.
Trail repair - Minimize spring flooding - Replace retaining wall

• Plants native to northwoods
symbolize water
• Informal seating on rocks
• Reminiscent of glacial geology
Path passes between twolarge glacial boulders atthe “headwaters” of the park

Hardwoods Biome
• Transition from coniferous to hardwood forest
• Management of the forest will allow the plant community to mature in a successional pattern

Prairie Biome
• Transition from hardwood/successional forest to grassland
• Limestone is characteristic of southern MN geology
• Landscape will be a year-round palate of changing colors and textures
• Limestone creates a gathering space for people
Limestone outcropping on a south facing grassland slope is a warm, quiet spot to rest
HILLOWAY PARK RENEWAL MASTERPLAN17 December 2002
South Entry - Hardwoods Biome
• Limestone creates a space that slows traffic down the steep decline
• Limestone, steep topography, and mature hardwood forest are characteristic of southeast Minnesota
A grouping of limestone pieces creates a gathering space at the south entry to the park
Bollard to slow traffic
Gathering and Entryspace created by limestone

Addressing Management Issues
1. Prescribed burns (all three biomes would benefit from some level of burning)
2. Chemical (herbicide)
3. Mechanical (machine driven) followed by broadcast herbicide treatment(s)
4. Physical removal (hand pulling; cutting; weed wrench) followed by broadcast herbicide treatment(s)
Tools to Control Invasive Species at Hilloway Park
Treatments range in effectiveness and cost but a combination of removal techniques which includes prescribed burning is necessary
HILLOWAY PARK RENEWAL MASTERPLAN17 December 2002
Addressing Management Issues
Viability of Pine Stands
Current Setting
Proposed “Restoration”
Removal of invasive species
Thin over-planted canopy
Promote canopy, understory and ground layer regeneration
Diversify pine plantation
Removal of invasive species will open up the park for views and native vegetation
Security compromised by tight enclosure by dense invasive shrubs
HILLOWAY PARK RENEWAL MASTERPLAN17 December 2002
Addressing Management Issues
Coniferous Sapling Deciduous Sapling
4’ Minimum tree shelter height for protection from deer browsing
Mulch to reduce light, moisture and nutrient competition
- LOCATE DESIRABLE SEEDLING
- PROMOTE AND PROTECT GROWTH
Desirable sapling - vulnerable to deer browsing and “suffocation” by invasive species
Tools to Control or Mitigate the Over-whelming Deer Population1. Removal2. Repellents (scents)3. Tree shelters4. Removal of exotic species cover (this will create a “more open” park,
which will be less desirable habitat for deer)
