Brooklyn to host the North American Green Roofs conference 2015

Cities Alive, the conference dedicated to green roof research, policy, design, and technology in North America, will celebrate its 13th year by coming to NYC this October. The conference moves to a different city each year to help familiarize our metropolises with this technology.

The conference will include the Harlem Design Charrette, which involves the green infrastructural re-envisioning of blocks of Harlem (under the aegis of the Canaan Baptist Church of Christ in Harlem); as well as multiple tracks of presentations over 4 days including research on biophilic principles of design. 

The final day will be dedicated to tours of NYC green roofs.

Board approval and the roof garden

DREAM GARDEN

When seeking a condo or co-op you might have the good fortune to come across one with a terrace or rooftop. This apartment has the potential to be life-changing! You could spend your mornings out there with your tea and laptop; or the kids could learn to grow tomatoes and basil in a pot; or maybe you could throw dinner parties, have a barbecue. Or just look out the window and see the garden! That in itself would be incredible.

The reality is: All of this can come true. However. There is a process.

It's call The Approval Process.

GETTING STARTED

To get started, hire a landscape designer experienced in working with Boards, building management, reviewing architects and engineers, and building superintendents in designing and installing rooftop gardens. This will save you time and headaches.

Contact your Board and request a copy of the terrace guidelines. Depending upon the age of your building, these may or may not be available. Terrace guidelines will specify the weight limitations and other requirements for a garden. 

[Ideally, you will think to ask for a copy of the terrace guidelines before you make your purchase, if an outdoor space is very important to you. Most buildings will have reasonable terms for limitations for a roof or terrace garden, but sometimes--very rarely--you will find that a building will not permit irrigation systems or any plant taller than 3 feet!]

Your designer will review the guidelines and use them as the basis for the design.

DESIGN REVIEW

You and your designer have progressed through preliminary designs for the garden, looked at costs, and moved into a final design phase. Understanding that the Board, building management, building's architect or engineer may refuse certain aspects of the design during the first go-round, you know that this final design may face additional alterations. 

A Board approval package is submitted. The approval package contains the design plan, weight calculations, construction details, and specifications. The Board hands this package to building management, who in turn hand it to the reviewing architect/engineer. Sometimes the building's superintendent looks it over as well.

The building's architect/engineer will return the approval package with questions and rejection of some items. Your designer will review the comments and propose alternative methods for maintaining the design elements, to determine whether those items which have been rejected can remain part of the scope (usually, there is a way). 

This "conversation" between designer and Building, conducted through drawings, specifications, calculations, on-site meetings and conference calls may take a couple of weeks or it may take months, depending upon the complexity of the project and the Building. A knowledgable designer will build good relationships with all the players involved and collaborate with the client and the Building to arrive at the best outcome.

DOB FILING
If the garden elements are entirely "temporary," i.e. not structurally fixed to or altering the building, then they will not be filed with the DOB. If the building requires an alteration such as pitch pockets to attach a fence to the roof, then this will be filed with the DOB. This process can take a few of weeks or longer if there is necessary back-and-forth.

INSTALLATION

The installation process may involve working with building-specified contractors based upon the Board's approval of the project. For example, if pitch pockets are required to attach a new pergola to the roof, then the building's roofer will need likely need to be hired to install these, in order to preserve the roof waterproofing membrane warranty. Your design/build firm will coordinate this work with, for example, the metalworker who has fabricated the pitch pockets and will be fabricating and installing the pergola.

APPROVAL PROCESS: ITS OWN SPECIAL LANGUAGE

The approval process can seem daunting. At first, it can appear that the garden one dreamed of has received a resounding "NO!" from the Board and that one will have to just set some pots and plants on the terrace and call it a day. This is almost never the case. Through discussion of alternatives, it is usually possible to find a solution and to find a way to turn "no" into "yes." Very occasionally, there is a Building that will be unmoved by all solutions presented, but in that case, the extremely strict limitations almost always will be outlined in the terrace guidelines as a warning: Buyer beware! Most Buildings are interested in finding solutions, provided the conversation is clear and measurable. Your designer may hire a structural engineer to help argue the case for contested elements--for example, to determine location of structural beams or review weight distribution of plantings, or calculate wind loads of fences or shade structures and recommend material thickness and attachments. 

Dream gardens can almost always come true but like most things in city life, there are forms that need to be filled out. Work with people who know how to fill them out properly so that you can make the most of that rare delight, the private roof garden. 

Are you a plant xenophobe?

Echinacea purpurea (Purple Coneflower) is a native to eastern North America. However, as was pointed out at the recent Ecological Landscaping Association's conference in Springfield, MA, many of the plants we call Native today were new to this continent at one point--say 10,000 years ago, for example.

Would you turn up your nose at a lupine from the other side of the Rockies? Refuse to hobnob with anyone who is unconcerned about woolly adelgid and the deterioration of our hemlock forests?

The 17th annual conference of the Ecological Landscaping Association held last week in Springfield, MA walked the tightrope on these and many other questions.

On the one hand, native plants were lauded for supporting native fauna like no other. The Karner blue butterfly, for example, relies on wild lupin for its reproduction. It lays its eggs on lupin leaves and its caterpillars then eat the leaves they are born on. However, the butterfly cannot distinguish between the species lupin (Lupinus perennis) and lupin relatives that have wandered over the Rockies and put down roots on this side of the Continental Divide. The consequence is that the blue Karner butterfly lays its eggs on this wrong-lupin and its caterpillars are unable to thrive on its leaves--and so do not survive. Another butterfly needing help from gardeners: the monarch. The milkweed plant (Asclepia tuberosa) would love to play host to it, but is itself getting wiped out by increased development and destruction of its habitat.

On the other hand, ecologist Jono Neiger peered into the controversy surrounding native vs. invasive plants and challenged many cherished ideas on the grounds that many long-adapted North American plants were at one time not indigenous to this continent, and that even the hemlock (the cause of as it is widely infested by an insect from Asia) disappeared at one point from the North American fossil record, and then returned. While not advocating recklessness or indifference to the fate of native flora and fauna, Neiger drew attention to the intense feelings and warlike language used concerning Invasive and Non-Native plants, and questioned whether the emotion directed at plants newly arrived to the continent or the energy invested in eradicating and avoiding the usage of these plants was significantly helpful. Ultimately, he asked, since addressing the issue of invasive plants has little impact on the elevated carbon dioxide levels in the atmosphere, should we be focusing our energies on other, more valuable solutions to the urgent problems facing the planet?
