Construction Update: Trees

/in , , , , , /by

The following is a blog post written by Asani President Marja Preston in March 2012 on the subject of trees on the Grow Community construction site. With the second phase of construction beginning, this is again an important subject to explore. Now that construction has begun, we can share more on how we plan on saving and re-using trees on the site.

1. Working with professional arborist Katy Bigelow, we walked through the property to designate significant trees to save and to remove trees that presented a danger to the neighborhood.

2. Several trees that required removal have been used as stream bank restoration for salmon habitat by the Kitsap County Surface and Stormwater Management Program.

3. Much of the cleared material will be re-purposed on-site for construction material, playground sites, and erosion control.

4. We will be replanting more trees (~250) than we remove.

Here is the original blog post:

Part of the careful planning we’ve put in place for this project includes everyday environmental choices that incorporate the beauty of our surroundings. This project is in the R-14 zone, which, under the new land use code, does not require retention of existing trees on the site. The Grow project will meet Built Green 5-Star certification, which requires substantial tree retention. In addition, we are committed to contributing to the long-term tree canopy goal of 50% coverage in Winslow, as outlined in the Bainbridge Island Urban Forest Management Plan.

In order to meet all these goals, our plan is to retain existing vegetation as much as possible. To accomplish this, we continue to work with a professional arborist, Katy Bigelow, to identify the maximum amount of trees that can reasonably be retained with the urban density that is planned. From here, once all trees have been identified, a service such as Gosnell Tree & Landscape or a similar company will be contracted for the removal of the selected trees.

We have focused on retaining trees in clusters and larger areas, for instance, at the corner of Grow Avenue and Wyatt Way, to maintain native vegetation areas, preserving habitat and maintaining existing green corridors. In addition, we are planting more than 250 new trees throughout the site. The new vegetation will enhance the existing green corridors and contribute to stormwater uptake and carbon sequestration, absorbing more than 900 metric tons of carbon over the next 100 years, almost double what the existing trees would have absorbed over that same time period.

As with all projects designed for urban densities, some trees must be removed, as preserving large trees next to new construction rarely works in the long-term. For the trees that do need to be removed or relocated we are taking the utmost care. All trees marked for preservation have been fenced at the dripline and no root systems will be disturbed by heavy equipment. Several Vine Maples have been saved for reuse in the project, a Dogwood is going home with one of our Contractors, several other plants will be going to a local landscaper, and we are working with the Kitsap Conservation District to salvage evergreens for Salmon Restoration projects.

Is Johnny Cash moving to Grow Avenue?

We’ve been getting a lot of questions at the GROW site regarding the new homes being built along Grow Avenue. Mostly, people seem interested in the progress on the site, when the homes are going to be ready for touring, and why they appear to be being painted black and if we plan on leaving them like that. Our Project Manager, Greg Lotakis, laughed and said he thought it looked like Johnny Cash – the infamous ‘Man in Black’ – was moving to the Grow Community.

You might be a little disappointed to learn that the late, great Johnny Cash is not moving to Bainbridge Island. You will, however, be happy to learn that we aren’t planning on building black homes along Grow Avenue, but are instead, in the process of building some of the most energy efficient homes in North America.

What you’re seeing going up on the first model home at the Grow Community is a weather resistant barrier system called Enviro-Dri, created by Tremco. We chose Enviro-Dri, as opposed to more familiar home sheaths like Tyvec, because the product is top in its class for weather resistant barriers and works for the life of your home to remove moisture and fight molds and mildew, an important aspect to home building in the Pacific Northwest.

Each of the three model homes will be constructed using slightly different wall systems and materials.  We will be testing and monitoring each combination for effectiveness and cost efficiency.  The next home will be coated with a similar product called StoGuard Gold Coat.

As we learn more through the application of each of these different products, we will be posting our thoughts and inviting your feedback.  Let us know in the comments if you have any questions or connect with us on Facebook and Twitter for all the latest news and information on the Grow Community project.

Wondering What’s Going On at the New Construction Site Along Grow Avenue?

/1 Comment/in , , , , /by

Those of you who have driven by Grow Avenue have seen that we have started construction and may be wondering what we are up to.  We have recently begun construction of three model homes that will be prototypes for the Grow Community. The model homes face Grow Avenue and are intended to showcase the different designs and floor-plans which will be available throughout the site. Construction will be complete and the homes available to tour mid-summer.

Grow is the first endorsedOne Planet Community to build residential homes in the United States. A One Planet Community is built to the highest standards for environmental, economic and social sustainability. One Planet takes development beyond the standards of LEED, requiring not only sustainable building design, but sustainable lifestyle design. The Grow project pays attention to every detail – not only how buildings are built, but how people live in those buildings. We at Asani believe that our built environment affects our health and happiness and are building Grow to reflect our needs as social creatures as well as the needs of the planet.  With solar power on the roof, a garden in the backyard and a car share program on-site, it will not only be easy, but affordable and fun to live a zero-carbon lifestyle at Grow.

To accomplish this, our team has designed incredibly energy efficient homes which will provide residents with an easy way to live a carbon-free lifestyle.  We have worked hard to balance cost considerations with the latest in building systems and technologies. The homes you see under construction just now are model homes that will be used to test not only the various energy-efficient building designs and systems, they will also be used to gather feedback on the home layout and design, as well as the One Planet living concept.

If successful, these models will be turned into actual residential facilities that can serve as a sustainable home to many people. The same model may be replicated soon across the country with ample help from construction companies in jacksonville fl as well as other cities in which the One Planet living concept may be implemented. Construction practices for residential homes are taking a turn towards more sustainable processes which can facilitate a bigger change in the coming years. More and more people seem to be recognizing the value of living in energy-efficient homes with plenty of natural light and surrounded by greenery. Not only is this a great step towards protecting the Earth, but also towards a healthier lifestyle.

The three homes that will be available for touring in the next couple of months are the Aria, the Ocean and the Everett.The Everett, the largest of the group, is a single-family, 3 bedroom dwelling meant to comfortably house a family.  With a study, a mud room, a playroom and endless storage, this is the perfect family house. The Ocean is an intergenerational home designed for main-floor living with a master suite on the ground floor.  A second master suite and roof-top deck on the second floor make this a flexible house for all different living situations. The Aria, a 2-bedroom single family dwelling with a light footprint, has tons of space and is perfect for a young family.

As these homes go up we will be sharing more about the designs and the thought-process behind the sustainability choices we have made.  We will be sharing our mistakes as well as our successes.  We look forward to an open dialogue as we learn and hope that our efforts will spark new and interesting discussions around sustainable design.

Check back next week for more details on the energy-efficient wall designs being tested at Grow and for general construction updates and progress reports. Let us know if you have any questions, comments or concerns here in the comment section, or onFacebook and Twitter.
