The majority of the parcels within the project area are currently served by onsite sewage treatment and disposal systems, also known as septic tanks. Gravity sanitary sewer and manholes will be installed along the center of the roadways with the flow traveling south to connect to the existing City of Longwood Wastewater Pump Station on E Wildmere Avenue. The project also encompasses some small lift station upgrades, and the installation of a parallel 8-inch force main along S Grant Street to accommodate the additional flow. 1.2 Justification for Proiect A majority of the septic systems in project area have been in service for over 30 years and have surpassed their design life expectancy. Replacement costs for failing septic systems continue to increase and regulatory requirements are becoming more stringent. Failing septic systems increase the risk of serious health and safety conditions for residents within the affected areas and can have detrimental environmental impacts to surface and groundwater sources. Installation of a sanitary sewer system to provide wastewater service as a replacement to septic tanks and drainfields will provide a healthier and safer environment for the residents living in this area; and in the long-term be more cost efficient as the cost to replace septic systems is rising. 1.3 Proiect Location Map The South Longwood Septic Tank Abatement project is located in the City of Longwood and encompasses approximately 250 acres. The project area is bordered by SR 434 to the north, East Street to the east, Wildmere Street to the south, and CR 427 (Ronal Reagan Blvd.) to the west. The project study area is located within Seminole County Commission District 4, and Section 5, Township 21S, Range 30E. Approximately 3.5 miles of roadway located is located within the project area including: Maine Court, Maine Avenue, Lake Avenue, Reider Avenue, Tullis Avenue, Oak Street, Oleander Street, and Grant Street. Land use within the area is a mix of vacant lots, single family homes, multi -family homes, and warehouses. A project location map identifying the project area is provided as Figure 1-1.

No Action 2. Gravity Sewer and Force Main Extension 3. Low Pressure Sewer Installation Below is a general summary of the advantages and disadvantages of each alternative. Alternative No. 1 No Action Advantages: • No disruption due to construction activities. • No additional maintenance required for the City of Longwood. Disadvantages: • Potential septic tank failures, resulting in costly replacements for the homeowners. • Public health threatened by failing septic tanks. • Continued excess nutrient runoff into nearby lakes and streams. Alternative No. 2 Gravity Sewer and Force Main Extension Advantages: • Lower operational and maintenance (O&M) costs associated with the gravity system component. • Very reliable operation and the City of Longwood is familiar with O&M of the systems. • Power outages have minimal impact to property owners connected to the system. • No additional O&M costs to the property owner. • Increased property values. Disadvantages: • Minimum pipe size of 8-inches. • Higher construction costs due to pipe size and depth requirements to maintain minimum slopes and avoid conflicts. • Manholes required at maximum intervals of 400-ft. B 2-1 Planning Report City of Longwood plbTORJ South Longwood Septic Tank Abatement i,ovoou t(NIDA 2.2 • Inflow/Infiltration (Ul) increases with age of system. • Construction activities are very disruptive. • Congested corridors with existing utilities and drainage infrastructure increase construction cost. Alternative No. 3 Low Pressure Sewer Advantages: • Lower construction costs due to smaller pipe size and trenching requirements. • I/I minimized. • Minimal disruption during construction. • Construction can be can be accommodated in highly congested corridors with existing utilities and drainage infrastructure without a significant cost increase. • Increased property values. Disadvantages: • Flushing connections required at regular intervals and terminal locations. • Grease buildup greatly reduces system performance. • Pumping systems are required at each connection to the system. • The City of Longwood does not normally utilize small grinder pump stations throughout their wastewater collection system and O&M of these systems would result in increased costs to the City. • Air release valves required at high points in the system. • Long term power outages can result in overflows at properties connected to the system. • Public education requirements for property owners associated with O&M of the pump systems, emergencies, and how to avoid blockages. Cost Comparison A present worth analysis has been developed for each acceptable alternative. The cost of maintenance and replacement of septic tanks in the project area, including adverse impacts to the general public and environment make Alternative 1 unacceptable. Capital and O&M costs as well as the present value for Alternatives 2 and 3 are provided in Tables 2-1 and 2-2. The present values were determined using the following information: • Planning period of 20 years. • Discount rate of 3.36%. • Estimated construction costs. BFA 2-2 Planning Report City of Longwood South Longwood Septic Tank Abatement • Estimated maintenance costs. LONooD ," ° IDI • Construction costs for Alternative 2 were determined based on a review of recent costs for similar projects. • Construction and O&M costs for Alternative 3 were determined based on the 2010 Performance & Cost of Decentralized Unit Processes published by the Water Environment Research Foundation (WERF).

Impact to Downstream Receiving Facilities 2. System Reliability/Operational Concerns/City of Longwood Familiarity 3. Community Acceptance 4. Disruption Due to Construction Relative scoring criteria and considerations associated with each factor are summarized as follows with each alternative being scored on a scale of 1 to 3. Each factor is also assigned a weight based on relevant importance to the decision making process. 1. Impact to Downstream Receiving Facilities Alternatives that do not require upgrades to downstream receiving facilities receive the highest score. An alternative requiring significant capacity upgrades would receive a score of 1. (10% Weight) 2. Svstem Reliability/Operational Concerns/City of Longwood Familiaritv Alternatives that have a proven record of reliable service, minimal operational concerns and are familiar to the city receive the highest scores. (25% Weight) 3. Community Acceptance Alternatives that would have the highest level of community objections or concerns with on -lot facility costs and O&M requirements would receive the lowest scores.

BFA ---- 2-6 Planning Report City of Longwood South Longwood Septic Tank Abatement 3.0 ENVIRONMENTAL EFFECTS/BENEFITS 3.1 Environmental Affects The project area within the City of Longwood is currently developed with primarily single- family homes and some multi -family development. Since the site already lies within an established community, the South Longwood Septic Tank Abatement Project is not anticipated to pose a threat or adversely affect threatened or endangered flora and/or fauna, surface waters, wetlands or undisturbed natural areas. Based on the location of the project area, a protected species list was developed using information from the U.S. Fish and Wildlife Service and attached in Appendix A. During Final Design Engineering a qualified biologist will survey the area to identify if there are any endangered, threatened or species of special concern present. Should any endangered, threatened or species of special concern be identified in the project area, the appropriate action shall be taken in conjunction with all federal, state and local jurisdictional agencies. The project will not have any significant adverse health effect to human health or environmental effects on minority or low-income communities. 3.2 Environmental Benefits As septic systems age, buildup of organic material causes a loss of infiltrative capacity of the subsurface soil dispersal system which can cause ponding, and in severe cases surfacing of untreated effluent. In addition, older septic systems generally were installed to lower standards with less oversight in comparison with new systems. Installation of gravity sewer will reduce excess nutrient runoff and prevent future septic system failures. This excess nutrient reduction will help prevent eutrophication in the nearby lakes and streams. The total anticipated load reduction from the project is approximately 7,440 lbs. of total nitrogen and 1,200 lbs. of total phosphorous annually. Installation of a sanitary sewer system to provide wastewater service as a replacement to septic tanks and drainfields will provide a healthier and safer environment for the residents living in this area; and in the long-term be more cost efficient as the cost to replace septic systems is rising.
