5 EXHIBIT 16 STORMWATER MANAGEMENT & EROSION AND SEDIMENTATION CONTROLS Motherhouse Senior Housing Subdivision and LIII Site Plan Application June, 2015 The project has been designed to meet the DEP Chapter 500 and City of Portland Chapter 32 Stormwater Standards for stormwater management. The site does not currently contain any stormwater mitigation facilities. Currently surface flows are either collected in on-site catch basins and piped to one of two discharge pipes located under the athletic fields on Lot 4 or flow overland to the west to the wooded wetlands located at the base of the slope to the athletic fields. The proposed site development will result in a minimal increase in impervious and developed areas due to the existing levels of pavement which will be removed or redeveloped as new parking, access drives and walks. Mitigation and treatment of the new paved and developed areas will be accomplished with the installation of two bio-cells (rain gardens) installed in grassed island on the west side of the main parking lot. The rain gardens will outlet to the existing stormdrain under the athletic field and to the wetlands to the west. A drainage easement will be provided on Lot 4 over the existing drain line which will be amended in the future to integrate with the Lot 4 development stormwater system as future phases of development occur. Refer to the separately bound Stormwater Management Report and Erosion and Sedimentation Control Plan report prepared by FST accompanying this submittal. 35 Fran Circle, Gray, Maine rlicht@securespeed.net V F

WHITCOMB COMMISSIONER June 26, 2015 VIA ELECTRONIC MAIL Frederic Licht Licht Environmental Design, LLC 35 Fran Circle Gray, ME Re: Rare and exemplary botanical features in proximity to: Job , McAuley High School, Portland, Maine Dear Mr. Licht: I have searched the Natural Areas Program s Biological and Conservation Data System files in response to your request received June 26, 2015 for information on the presence of rare or unique botanical features documented from the vicinity of the project site in Portland, Maine. Rare and unique botanical features include the habitat of rare, threatened, or endangered plant species and unique or exemplary natural communities. Our review involves examining maps, manual and computerized records, other sources of information such as scientific articles or published references, and the personal knowledge of staff or cooperating experts. Our official response covers only botanical features. For authoritative information and official response for zoological features you must make a similar request to the Maine Department of Inland Fisheries and Wildlife, 284 State Street, Augusta, Maine According to the information currently in our Biological and Conservation Data System files, there are no rare botanical features documented specifically within the project area. Based on the information in our files and the landscape context of this project, there is a low probability that rare or significant botanical features occur at this project location. This finding is available and appropriate for preparation and review of environmental assessments, but it is not a substitute for on-site surveys. Comprehensive field surveys do not exist for all natural areas in Maine, and in the absence of a specific field investigation, the Maine Natural Areas Program cannot provide a definitive statement on the presence or absence of unusual natural features at this site. The Natural Areas Program is continuously working to achieve a more comprehensive database of exemplary natural features in Maine. We would appreciate the contribution of any information obtained should you decide to do field work. The Natural Areas Program welcomes coordination with individuals or organizations proposing environmental alteration, or conducting environmental assessments. If, however, data provided by the Natural Areas Program are to be published in any form, the Program should be informed at the outset and credited as the source.

9 Letter to Rick Licht Comments RE: McAuley High School June 26, 2015 Page 2 of 2 The Natural Areas Program has instituted a fee structure of $75.00 an hour to recover the actual cost of processing your request for information. You will receive an invoice for $ for our services. Thank you for using the Natural Areas Program in the environmental review process. Please do not hesitate to contact me if you have further questions about the Natural Areas Program or about rare or unique botanical features on this site. Sincerely, Don Cameron Ecologist Maine Natural Areas Program don.s.cameron@maine.gov
