3 Columbus State Community College MASTER PLANNING EXISTING UTILITIES AND FACILITIES ASSESSMENT Introduction This report presents the current state assessment of the existing Columbus and Delaware Campus and facilities utility infrastructure including water, sanitary sewer, storm drainage, gas, and electrical systems. Analyzing current state utilities and facilities information is critical in assessing existing infrastructure needs and evaluating the capacity of utilities to support projected campus growth. This information was collected as part of the data gathering phase of the master planning process. Detailed recommendations for improvement of these utilities or facilities are not in the scope of the study and hence not included in the report. Generally, the utility systems on Columbus Campus have adequate capacity to serve the existing development and support future growth. Further study and additional coordination with the appropriate Utility Owners (City of Columbus, Columbia Gas, etc) will be required as the master plan is further developed. The Delaware Campus utility systems generally perform adequately for the existing development and have been sized for the future expansion of the campus to the west. As the present master plan develops, and development plans are actualized, further study of the utility systems will be required for the Delaware Campus. Maintaining and expanding the sustainable features of the Delaware Campus s stormwater management system should be a high priority. Existing Utilities Assessment Assessment Methodology Municipal and utility company index maps, existing master plans, review of existing Columbus State facility assessment documents and drawings, and conversations with College staff were instrumental in acquiring the information necessary to prepare this infrastructure assessment. For the Columbus Campus, water distribution maps, sanitary sewer maps, storm sewer maps and detailed engineering drawings were acquired from the City of Columbus Division of Power and Water (DOPW) and Division of Sewerage and Drainage (DOSD) for analysis and inclusion in the report. Utility maps for the Delaware Campus were acquired from the College. Columbia Gas of Ohio provided maps of its natural gas distribution network for both campuses. 1

4 Water Distribution The City of Columbus DOPW owns and maintains the Columbus Campus existing water distribution system shown on Exhibit 1. The various Columbus Campus buildings are individually metered and connected to the DOPW mains via private water service lines. Based on conversations with DOPW personnel and analysis of their existing documents, no major water facility improvement projects are planned in the near future. The existing system has adequate capacity and flow as it is serves directly from the Dublin Road Water Plant. A recent DOPW Master Plan did not identify any DOPW owned water mains in the Columbus Campus that required significant improvements. In general, based on discussions with Columbus State personnel, DOPW engineers, and review of existing documentation, the water distribution system provides adequate and reliable water distribution to campus irrigation and building supply needs. The Delaware Campus water distribution system (existing and future) is shown in the schematic diagram below. The existing system has adequate capacity and flow for not only the existing campus and building supply needs, but to accept future expansion to the west.

5 Sanitary and Storm Sewer The Columbus Campus sanitary, storm, and combined sewers are a combination of private and public systems owned and maintained jointly by Columbus State and the City of Columbus DOSD. The sewer facilities (pipes, manholes, and catch basins) located within private property (parking lots, court yard areas, etc) are currently maintained by Columbus State facilities maintenance personnel. The sewer facilities within the public right of way are owned and maintained by DOSD. The Columbus Campus existing sanitary and storm sewer system maps are shown on Exhibit 2. Based on discussions with various DOSD staff, the City does not have any major sewer projects planned within the Columbus Campus in the near future. A Sewer Separation Study prepared for DOSD in 1976 and revised in 1986 identifies combined sewer systems on the Columbus State campus that were planned for separation in the future. Although these studies exist, DOSD personnel have indicated there are no plans to perform these separation projects in the near future. The combined sewer mains are clearly shown in the attached Exhibit 2. The existing sanitary sewer system for Columbus Campus appears to have adequate capacity to serve the Campus needs. A full sanitary sewer study may be required in the future to evaluate the infrastructure needs based on the completed master plan. DOSD records show no significant stormwater flooding complaints in the Columbus Campus area. There are adequate storm sewer inlets and piping available to intercept and convey rainwater runoff for the typical rainfall event. Less frequent and heavy rainfall events with peak bursts cause short term localized flooding on several Columbus Campus streets. Long duration rainfall events without peak bursts are conveyed successfully by the existing storm water management system without causing significant flooding. Based on discussions with Columbus State personnel, DOSD engineers, and review of existing documentation, the storm and combined sewer system provides adequate and reliable rainwater conveyance from the Columbus Campus. 3

6 The Delaware Campus sanitary and storm sewer systems were designed to support future expansion on the over 108-acre site. Sustainable stormwater features such as vegetated bioswales which capture runoff from building rooftops and parking lots are incorporated into the overall stormwater infrastructure for this campus. A regional water quality retention pond with deep and shallow water areas intercepts stormwater runoff from the entire campus prior to releasing it to the municipal storm system adjacent to US Route 23.

7 Natural Gas The natural gas system serving both the Columbus and Delaware Campuses is a private utility owned and operated by Columbia Gas of Ohio (COH). The COH low, medium, and high pressure gas mains in the vicinity of the Columbus campus are shown on Exhibit 3. Internal to the campus, Columbus State gas service lines are fed from the COH mains to individual buildings. It appears metering is done at the individual buildings. All operation and maintenance of the natural gas system is performed by COH. The low pressure and medium pressure systems are clearly differentiated in the Exhibit. Based on and telephone correspondence with Columbia Gas, the low pressure gas mains at the southwest quadrant of the Columbus Campus are planned for total replacement in the next years.

American Electric Power (AEP) provides power to the Delaware campus. 5

8 Existing Facilities Assessment Assessment Methodology Review of existing Columbus State facility assessment documents, and conversations with College staff were instrumental in acquiring data necessary to provide current state assessment of the existing building systems. Detailed recommendations for improvement of these systems are not in the scope of this report. Additional facilities information gathered from existing documentation prepared by Columbus State Facilities staff, anecdotal knowledge of users/facilities, and physical observations are documented in the attached Exhibit 4: Building Status Matrix. Electrical systems As noted previously, the City of Columbus Department of Public Utilities provides power to the Columbus Campus and owns and maintains the service transformers. AEP provides power to the Delaware campus. Emergency power is provided by both diesel and natural gas generators and generally serves life safety systems and is adequate, but it is desired to extend emergency power to 384 N. Sixth (Vet Tech) to protect the animals. According to Columbus State Facilities staff, the electrical systems in the existing buildings are generally well maintained and based on our cursory walk- through are acceptable for the current use. Some distribution equipment is original to their respective buildings and is beyond its useful life according to industry standards. The lighting systems are generally good or adequate although several building s systems have been identified as poor by the staff either due to their low energy efficiency or inadequate illumination levels. Based on extensive energy audits, including the October 2008 Energy Efficiency Plan, it is expected that most of the buildings identified as poor will be removed from this poor status upon completion of the recommendations in the Plan. Facilities information gathered from existing documentation, anecdotal knowledge of users/facilities, and physical observations are documented in the attached Exhibit 4: Building Status Matrix. A more detailed assessment of the buildings electrical systems is not included in the scope of this report. 6

9 Mechanical Systems There are several Columbus Campus buildings that have been upgraded to utilize high efficiency boilers and variable frequency drives where applicable. However, there are also several buildings that have HVAC equipment that is at the end of its useful life that should be replaced with new high efficiency boilers and fans and pumps with variable frequency drives. In some cases there is existing equipment that has oversized equipment that is causing controls issues during part load conditions. Any upgrade should have new load calculations performed to ensure that actual load conditions are used to size any replacement equipment. The controls systems across campus have been standardized on Johnson Controls in all but a few buildings. We recommend that gathering the information from the entire campus through centralized monitoring be implemented to take advantage of the standardization of controls systems type. Facilities information gathered from existing documentation, anecdotal knowledge of users/facilities, and physical observations are documented in the attached Exhibit 4: Building Status Matrix. A more detailed assessment of the buildings HVAC systems is not included in the scope of this report. 7
