Last Spring, NOFA OLC held a Permaculture Design Workshop at my house, since my .1 acre property provided so many common design and landscape challenges for the landscaper to ponder.
Most prominently, we had major stormwater issues, with the concrete driveway falling apart and the basement leaking. In addition, we had an over abundance of concrete pathways in the yard, taking away valuable growing space. My husband had been parking his truck on 1/4 of the yard space- a practice which I was officially ending on the day of the workshop - which led to compaction and probably small amounts of oil and automotive fluids leaking into the mixture of gravel and sand.
On the more fun and functional side, we were interested in designing the yard to maximize usage of space so humans had a place to lounge and grill, a kid could run through a sprinkler, and ornamental and vegetable plants were well-placed. I also wanted to incorporate the rabbit hutch and future chicken house into the yard, where they would be best suited.

1. Soil Testing - Prior to the workshop, I was pretty upset to learn that my soil had 900ppm lead, which made it unhealthy to harvest any root veggies or leafy greens from the soil. However, knowledge is power, so we decided that the most important change we could make was to design raised beds and place them in the old parking space. There is one 15 foot raised bed which cost around $350 to build and fill with soil and compost. The second set of hoops covers 4 long rectangular planters which offer mobility if I want to move them. I also have cool weather crops like greens and chives in the planters. The large raised bed produced spinach, arugula and mixed greens all winter. I planted carrots and potatoes one month ago and just started some tomatoes last weekend.
The old vegetable garden would became lawn, with a few perennials like echinacea, day lillies and rudbeckia "herbstonne" around the outside border. Just this spring, I added a raised bed wooden box and transplanted my black raspberries since they were getting a little unwieldy. I also have a box of garlic, which I will move someday. I have to admit, I am pretty impressed with my lawn which I planted with a seed mix called Tuff Turf and microclover from Good Nature Organic Lawn Care. This photograph also shows some of the old concrete pathways which will be removed at a later date. (It's on the list.)

The animal cages and outdoor run are situated along the outside edge of the property to maximize space and to utilize the windbreak which the solid fence provides in the winter. The compost bins were moved next to the tunnels last summer, but I think I will be moving them again so I can plant a paw paw tree in the sunny southern corner of the lot. I figure that by moving the compost, it is improving the soil in multiple places.
To maximize compost production, I collect bags of leaves from my neighbors in the fall, and keep them for shredding and adding to my compost pile all year round. My newest toy is a paper shredder which allows me to create carbon-rich, shredded paper, made from junk mail and out-of date paperwork, to balance out the kitchen scraps and manure in the piles. You want a 30:1 ratio of browns to greens, on average. Composting is so rewarding: you use your own waste products to create an excellent soil conditioner and fertilizer for your lawn and gardens. I estimate that my two bins create 20, 5 gallon buckets of finished compost per year. My goal is to not have to buy any bags of soil or compost, but for now I need about 10 bags per year for containers and over-seeding the lawn.

I also wanted to share the costs of such a project. It cost around $6000 to remove the concrete, haul it away, pay for dumping fees, 3 days labor, gravel and stone dust, and rent the excavator. I am lucky to have a husband who was willing to take this project on. (Or maybe he just didn't want his trucks falling into the sink hole!)
So I want people to feel empowered to make small, medium and large changes to our landscapes for both personal enjoyment, like having a grape arbor and using it for summer shade, and to benefit the environment, like growing flowers for pollinators. If all you can do this year, is over-seed your lawn with a packet of microclover to fill in the bare spots, adding a plant that will provide free nitrogen to your lawn, then that is just all you can do and it's good enough!
