BACK PATIO

FRONTIER FARM CREDITMANHATTAN, KS

The aim is simple: create comfortable atmospheres that reveal the beauty andfunctioning of the native Kansas Prairie. Truly this area of Kansas has muchto offer, and capitalizing on native plants will achieve the goal. The plantingdesign optimizing views both inward and outward views primarily from KimballAve and secondarily from surrounding businesses. Many of the surroundingcommercial businesses are screened from the patio area and building windows,but the panoramic view of Manhattan are sustained. The amazing East view ispreserved and framed by a row of ornamental Redbuds and Autumn Brilliance

Serviceberry. The walkway underneath these trees will be very experiential withfragrant flowers, stimulating colors, and the rustling of the waxy Marlot leaf in thewind. Primarily using native vegetation, with exception for extra ornamental value,ecotones were created using a layering of vegetation from the overstory of theOaks, to the herbaceous shrubs, down the short prairie grass underfoot. Layers ofvegetation are both comforting to humans, and also create an ecosystem for nativebiota. Using tree leaves as the medium, a variety of trees were used to offer many

Management Plan

Jake Jenkins

Bioretention areas require seasonal landscaping maintenance. In many cases, bioretention areas requireintense maintenance initially to establish the plants, but less maintenance is required in the long term.Monthly inspection of the soil must be conducted. If erosion occurs, this must be repaired. In additionlitter and debris must be removed. Due to the adaptability of the native species, no additional irrigation isrequired. Twice a year remove and replace dead vegetation. Mulch must be monitored and void spotsshould be replaced every two to three years. More visible bioretention areas must be monitored mostclosely. These areas are an educational component for visitors on the treatment of stormwater runoff.Additionally contributing to the functioning of prairie, an annual burn will occur in early spring. Only burnafter two growing seasons after an accumulation of plant material has occurred. Burning the prairie willpromote native species and destroy the non-natives of which would only be invasive on this site.

Initially the tallgrass prairie will require supplemental watering to propagate from seed, if rainfall is notregular and sufficient. After plants establish, they will not require watering even in the dry years becausethese grasses are drought tolerant. One of the biggest challenges is the suppression of weeds. Sincemost of the site is covered in tallgrass prairie without direct pedestrian access, weeds may not be aconcern. Spraying will be the best method for the reduction of weeds, particularly around the backpatio and other paved areas. Long-term maintenance involves simulating natural disturbance to keepwoody species from moving in and turning the prairie into a woodland. After plants have established, ascheduled burn in the spring will reduce the occurrence of weeds and woodies.

The shortgrass prairie species will grow in areas close to buildings and parking lots to open site lineswhile providing a low maintenance, native groundcover. Burning is not available in these areas, andmowing will be an effective substitute. Mow half the site on a rotating basis to retain adequate wintercover for wildlife. Mowing half in the fall will allow birds to finish nesting and prairie plants have set seed.Remove the cut stems because the thatch layer will provide an additional nitrogen source for weedgrowth. Removing the thatch will allow the sunlight the penetrate and encourage growth of prairie plants.

SPECIFICATIONS:

1. PLANTS

A. Plants shall be true to species and variety specified and nursery-grown in accordance with goodhorticultural practices under climatic conditions similar to those in the locality of the project for at leastone growing season. They shall be freshly dug (during the most recent favorable harvest season).

B. All plants shall be sound, healthy, vigorous, well branched, and densely foliated when in leaf; free ofdisease and insects, eggs, or larvae; and shall have healthy, well-developed root systems. They shall befree from physical damage or other conditions that would prevent vigorous growth. Trees with multipleleaders, unless specified, will be rejected. Trees with a damaged or crooked leader, bark abrasions,sunscald, disfiguring knots, insect damage, or cuts of limbs over 20 mm (3/4 in.) in diameter that are notcompletely closed will be rejected.

C. Balled and Burlapped (B&B) Plant Materials: Trees designated B&B shall be properly dug with firm,natural balls of soil retaining as many fibrous roots as possible, in sizes and shapes as specified in theAmerican Standard for Nursery Stock. Balls shall be firmly wrapped with nonsynthetic, rottable burlap andsecured with nails and heavy, nonsynthetic, rottable twine. The root collar shall be apparent at surfaceof ball. Trees with loose, broken, processed, or manufactured root balls will not be accepted, except withspecial written approval before planting. Proper planting depth requires the root flare to be at or slightly

above the finished grade.

D. Before backfilling, clean soil of roots, plants, sod, stones, clay lumps, and other extraneous materialsharmful or toxic to plant growth, and dispose of off site. Use only existing soil from the site as back-fill.

E. Plants shall not be heavily pruned at the time of planting. Pruning is required at planting time tocorrect defects in the t ree structure, including removal of injured branches, double leaders, waterspouts,suckers, and interfering branches. Healthy lower branches and interior small twigs should not beremoved, except where branches on the B&B trees are lower than 6 feet to the ground (to preventconflicts with 6-foot wire cages). In no case should more than one-quarter of the branching structure be

removed. Retain natural shape of the plant.

2. SEEDING METHOD

A. Broadcast Method: Broadcast by hand or knapsack seeder using the proper seeding rate, carefullyproportioning seed for the entire area. Sand or sawdust may be added to help proportion the seed.Increase accuracy by seeding half of the seed in one direction and the remaining seed in the otherdirection. Follow by rolling the seed into the top 1/4 inch of the soil to achieve good seed to soil contact.

Cover with an erosion control blanket of pure straw with polypropylene on both sides (use North AmericanGreen S150, or approved equal). Toe the erosion control blanket securely to the ground (installing theblanket per the manufacturers specifications).

B. Seeds: shall be viable, native seed from a nursery or supplier approved by the landscape architect/designer. All rates shall be per acre of pure live seed (PLS). Substitute grass and wildflower speciesshall be approved by the landscape architect/designer.

3. MAINTENANCE FOR SEEDED AREAS

First Year Maintenance - Observation of the growth of desired grass and wildflower species and weedcompetition are essential to making maintenance decisions. Each time that the vegetation in the seededareas reaches 12 to 18 inches tall, mow to no less than 10 inches by rotary mowing or weed-eater toprevent weedy vegetation from going to seed. Most native plants will grow deeper root systems thantops in the first year and mowing to 10 inches will not hurt them. Mowing allows sunlight to reach desiredspecies. Seeded areas should be mowed two or three times during the first year, depending on rainfalland vegetative growth, to reduce annual weed invasion and enable light to reach some of the smallwarm season grass seedlings. DO NOT MOW WITH LAWN MOWER. DO NOT MOW CLOSER THAN

10. Mowing lower than 10 damages grass crowns, and increases the mortality of warm season nativegrasses.

Second Year Maintenance - Mow grasses and wildflowers one time as close to the ground as possiblein early spring (by April 1 at the latest). This allows the soil to warm more quickly and young native plantsto emerge. It also allows birds and other wildlife to use the grasses and wildflowers during winter months.Then, mow once in late July or early August (mowing should not be done during the nesting season April 15 through July 30 to preclude killing groundnesting birds and their eggs or young). Mow nocloser than 10 inches.

Frontier Farm Credit provides communities withfnancing or operating needs such as labor, seed, andmachinery to grow the ood t hat supports themselvesas well as the rest o America. To this end they arelooking to create an o ce that shows their commit-ment to their goal as well as providing a connectionpoint with those that are not armers in Manhattan.In our design we have looked to provide identity orFrontier Farm Credit, connect with the communitythrough multimodal circulation throughout the siteand to respond the character o the rural communityas caretakers o the land.
