Title/Name/Summary
Village Hall Green Roof Project - Tree Preservation and Green Infrastructure Account
History
OVERVIEW AND BACKGROUND
There has been a strong Interest in establishing a green roof at Village Hall since at least 2011, when the Village worked with Christopher B. Burke Engineering (CBBEL) to develop an application for funding for a green roof on Village Hall via the Illinois Green Infrastructure Grant Program. Funding for the project was not awarded, and since that time, the Illinois Green Infrastructure Grant Program has been suspended.
In May 2017, the Village revived its efforts and took the first step in determining the feasibility of a green roof at Village Hall by having a structural analysis performed on the two (2) terraces on the north side of the 2nd floor of Village Hall. The analysis, which was performed by CBBEL, verified that both terraces have the structural capacity to allow for the installation of a green roof. Funding from the Village’s Tree Preservation and Green Infrastructure Account (TPGIA) was used to pay for the cost of the analysis.
In July 2017, to help offset funding for the green roof project, the Village Board of Trustees approved a resolution authorizing an application for an MWRD green infrastructure program matching grant request of $25,000. In November, 2017 the MWRD notified the Village that the green roof project had been selected for funding assistance. The MWRD highlighted the green roof project's storm water benefits, the capability of the applicant to operate and maintain the green infrastructure practices and the visibility of the project in terms of providing educational opportunities as key considerations in the Village being selected for the grant. A dollar amount was not established by the MWRD at the time of grant notification.
Subsequently, in February, 2018, the MWRD announced that the Village could receive $20,000.00 in grant funding if an intergovernmental agreement (IGA) with the MWRD was agreed to. To do so, the Village would need to comply with the Cook County MPLA (Multi-Project Labor Agreement), the MWRD Purchasing Act, Affirmative Action - Woman Owned, Minority Owned and/or Small business requirements and O&M Maintenance requirements. Given these numerous requirements, in addition to the ample staff time that would be required to manage the grant, the Village notified the MWRD that the awarded grant funding would not be used for the green roof. Since that time, Village staff has been working with the MWRD to find alternative options for the use of MWRD funding, most likely for larger scale green infrastructure projects within the Village.
The Village’s Tree Preservation and Green Infrastructure Account (TPGIA) was set up specifically for green infrastructure projects such as a green roof. As such, to avoid further delays and ultimately save time and money, a plan has been developed to install a green roof and observation deck area, along with associated amenities, utilizing Village staff manpower, green roof contractor expertise and TPGIA funding.
PROJECT DESCRIPTION & CONTEXT
Green roofs have proven to improve storm water management by reducing runoff and improving water quality, conserve energy, mitigate the urban heat island, increase longevity of roofing membranes, reduce noise and air pollution, sequester carbon, increase urban biodiversity by providing habitat for wildlife, provide space for urban agriculture, provide a more aesthetically pleasing and healthy environment to work and live, and improve return on investment compared to traditional roofs.
The goal of the Village Hall Green Roof project is to deliver an exemplary public green infrastructure project that will provide, in addition to ecological and storm water benefits, an engaging outdoor space at Village Hall. The Village of Orland Park’s green roof will be used as a pilot project to motivate business owners and developers to consider green roof or other green infrastructure projects as a part of their own developments. Additionally, the Village Hall green roof will create an educational and social gathering space accessible to the community. Quality accessory features/furnishings and a plant palette that provides visual interest from inside and outside Village Hall are also considered important to the overall success of this project.
The proposed location for this project are the two (2) second-floor terraces on the north side of Village Hall. The terraces overlook the Village’s storm water detention basin, which would directly benefit from the improved water quality generated by the green roof. The combined area of the project sites equals approximately 1,900 square feet (SF). Both terraces are visible from within Village Hall and will be accessible to the public. A new roofing membrane was installed on both terraces in 2016, and roof drains located within each terrace outlet to the Village Hall storm water basins. Decorative metal fencing surrounds all sides of the terraces. In addition to design and installation services, Village Staff will determine if modification of the roof membrane or roof drainage system is needed to accommodate the green roofs, and if so, to complete any such modifications.
Several ancillary improvements to Village Hall would also be addressed as a part of this project. Additionally, the wooded picnic tables currently on the east terrace would be relocated to enhance a different location on Village Hall grounds. Overall, the Village Hall Green Roof project would include the following scope of work:
- A 1,600 SF green roof with low-maintenance, adaptable plant materials
- One (1) year of green roof maintenance training
- Two (2) 150 SF observation decks
- Site furnishings for the deck areas
- Three (3) new exterior frost proof sill cocks
- Two (2) new exterior light fixtures
- Interpretive and educational signage
- Evaluation of waterproof surface integrity
- Evaluation of existing roof drainage systems
- Minor adjustments to the height of the existing terrace railings
- Equipment (e.g. hoses) for watering purposes
- An ADA accessible ramp and landing to be located on east side of the building
- A reconfiguration of second-floor doorways and signage to comply with ADA and OSHA requirements
PROJECT IMPLEMENTATION
Except for the installation of the three (3) new exterior frost proof sill cocks, all other installation labor associated with this project will be completed by Village staff, including members of the Parks, Building and Development Services Departments. To complete the project, proposals would be requested by the Development Services Department from subject matter expert (SME) consultants, in this case green roof professionals familiar with the supervision and training of a green roof installation team. The SME would be selected via a formal RFP process and Board approval would be required for the selected contractor. The selected SME would work with staff to finalize a design for the green roof, procure all green roof and decking materials, and supervise the installation of the green roof and decking by qualified Village staff. The SME would also train Parks Department staff on green roof installation maintenance, which would provide an educational benefit for staff and a viable option for the long-term maintenance of the green roof by the Village. The scope of work will include one (1) year of green roof maintenance training under the supervision of an outside subject matter expert (SME) consultant, after which time Village staff would take over the full maintenance of the green roofs.
Staff from Development Services, Parks and Public Works (Building Maintenance) would work together to select and install site furnishings, install electrical connections and fixtures, design and install signage, and complete all interior builing work. Village staff participation in the actual construction of this project will serve several purposes, but most prominently it will help to reduce costs and train Staff in green roof installation and maintenance. Exhibits showing a conceptual plan for the Village Hall Green Roof and estimated project costs is included with this report. Installation of the Village Hall Green Roof project would be completed during the fall of 2018.
DEVELOPMENT SERVICES, PLANNING AND ENGINEERING COMMITTEE
On 7/16/18, the Development Services, Planning and Engineering Committee recommended to the Village Board approval of the use of funds from the Tree Preservation and Green Infrastructure Account in an amount not to exceed $70,000.00 for the installation of a Village Hall Green Roof and associated amenities and services at the Orland Park Village Hall.
This request is now before the Village Board of Trustees for final consideration.
Financial Impact
Funds for this project are available in the Tree Preservation and Green Infrastructure Account (TPGIA) # 010-0000-223100. The total project costs, as outlined on the attached exhibit, is estimated to be $70,000 for both green roofs.
Recommended Action/Motion
I move to approve the use of funds from the Tree Preservation and Green Infrastructure Account in an amount not to exceed $70,000.00 for the installation of a Village Hall Green Roof and associated amenities and services at the Orland Park Village Hall.
