2. HILLOWAY PARK RENEWAL MASTERPLAN 17 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 Concept Plan Pine Hardwoods Prairie Biomes of Minnesota Pine Hardwoods Grass land N 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.

HILLOWAY PARK RENEWAL MASTERPLAN 17 December 2002 Pine Hardwoods Prairie Concept Plan Hilloway Park Concept Plan Pine Hardwoods Prairie Biomes of Minnesota Park entrance: see sketch Existing trail: - Re-surface gravel portion with pervious pavement or soil cement to reduce erosion of gravel Pine - 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 Park entrance - see sketch

HILLOWAY PARK RENEWAL MASTERPLAN 17 December 2002 Hardwoods Biome Transition from coniferous to hardwood forest Management of the forest will allow the plant community to mature in a successional pattern A clearing in the hardwood forest demonstrates re-growth and regeneration Grassland/Transition Early Successional Mature Hardwood Forest Forest Regeneration

9. HILLOWAY PARK RENEWAL MASTERPLAN 17 December 2002 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

10. HILLOWAY PARK RENEWAL MASTERPLAN 17 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 Entry space created by limestone

11. HILLOWAY PARK RENEWAL MASTERPLAN 17 December 2002 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

12. HILLOWAY PARK RENEWAL MASTERPLAN 17 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

13. HILLOWAY PARK RENEWAL MASTERPLAN 17 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 Population 1.Removal 2.Repellents (scents) 3.Tree shelters 4.Removal of exotic species cover (this will create a “more open” park, which will be less desirable habitat for deer)
