Shim, P.E. City Engineer/Utilities p irector SUBJECT: Presentation by PEC At the City Commission meeting on February 6, 1996, we have scheduled a presentation by Professional Engineering Consultants, Inc. during which they will provide information on several subjects. Attached for your review is a memorandum from Ken Hooper dated January 31, 1996 which enumerates the various topics to be discussed or acted upon. I. Drainage Update 1. PEC will provide information on the status of the various drainage basin studies. 2. Attached is a memorandum from PEC dated January 30, 1996 regarding estimated costs associated with the NPDES permit. 3.&4. PEC will provide information on the Drainage Maintenance Program and the Stormwater Capital Improvement Program. 5. Attached is a memorandum from PEC dated January 18, 1996 (revised January 30, 1996) summarizing a meeting attended by Mayor Vandergrift, Commissioner Anderson, PEC, and City staff. The purpose of the meeting was to discuss drainage issues raised by Mayor Vandergrift. II. Attached for your review is a document titled "City of Ocoee - Water Master Plan Summary." This provides an executive summary of the proposed Water Master Plan which will be our planning document for water system growth through the year 2014. THE PRIDE OF WEST ORANGE The Honorable Mayor and Board of City Commissioners February 2, 1996 Page 2 This plan will be discussed in more detail, and we will be ready to answer questions. Please note that our recent decision to utilize on-site sodium hypochlorite generation at the South and Forest Oaks water plants will eliminate the$332,000 cost for chlorine scrubbers shown on the cost summary. III. Attached for your review is a document titled "Reuse Feasibility Study." This document provides a brief overview of why the City is involved in the preparation of such a study, the current status of the City's wastewater reuse program, and our plans to expand the reuse program.. This program will be discussed in more detail, and we will be available to answer questions. IV. Attached for your review and action is a memorandum from Ken Hooper dated January 31, 1996 regarding the White Road Improvement project. The memorandum explains the process used to obtain construction bids for this project, and points out that the apparent low bid is approximately $250,000 below our estimated cost. In order to get the benefit of this price, the City needs to enter into a developer agreement with Homart. Since timing is critical, it would be appropriate for the City Commission to indicate its approval of the concept of such an agreement. With this conceptual approval, based on a construction cost of $646,215.54, Homart will include the White Road improvements in its contract with C.A. Meyer. The agreement between the City and Homart will be finalized as quickly as possible and will be brought before you for execution. I recommend that the City Commission move to give conceptual approval to a developer agreement between the City of Ocoee and Homart allowing Homart to construct the White Road improvements utilizing the services of C.A. Meyer for a fee of$646,215.54. JWS/jbw Attachments PEC PROFESSIONAL ENGINEERING CONSULTANTS, INC. MEMORANDUM TO: James W. Shira, P.E.

City Engineer/Utilities Director City of Ocoee 150 North Lakeshore Drive Ocoee, Florida 34761 Re: NPDES Permit Tasks and Associated Annual Costs Dear Mr. Shira: The purpose of this letter and its attachments is to provide you with a preliminary estimate of costs that the City of Ocoee (City) will incur in order to comply with NPDES Municipal Separate Storm Sewer System (MS4) permit requirements. These estimated costs represent new expenses attributed to the requirements of the Second Draft MS4 permit. The estimated costs include labor and other direct expenses. To assist you, the estimated annual labor expenses have been separated into maintenance and non-maintenance costs. MS4 permit requirements are organized into categories with general goals and objectives. These general categories are further defined by specific tasks. A Task Schedule listing all MS4 permit task requirements is provided in Attachment"A". Associated with each task is a task start date (all dates represent the number of months following the permit issue date), the frequency at which the task is to be performed, the task completion date (if applicable), and the date task activities and results are to be reported in the required annual report(s). All tasks will be completed by City staff and PEC staff. City staff includes a new NPDES Coordinator, City professional staff, City field staff, and the City Attorney. The estimated City labor requirements (in labor hours) are presented in Attachment"B°. The number of City employees needed to complete the required tasks was calculated by dividing the total number of hours in a staff category by 2080 hours (full-time employee). PEC staff will include a PEC project manager and required support staff. PEC labor estimates are presented in Attachment"C". A total labor cost estimate is presented in Attachment"D". Labor costs are shown as either maintenance or non-maintenance costs. Labor costs were determined by multiplying task- specific labor hours by the assigned hourly rates. All hourly rates include the standard labor multipliers used by the City and PEC. To account for cost of living increases, hourly rates are assumed to increase uniformly at a rate of 3% per year. engineers planners surveyors 200 East Robinson Street • Suite 1560 • Orlando, Florida 32801 • 407/422-8062 • FAX 407/849-9401 James W.

These "lump-sum" expenditures include capital expenditures, professional services fees, and training expenses. These expenses are summarized in Attachment "E". Heavy equipment cost estimates were obtained from information provided to PEC by the City's Accounting Department. Heavy equipment needs includes a new street sweeper ($130,000), a new dump truck($60,000), and a new riding mower($15,000). Equipment costs are reported in Attachment "E" as amortized expenses with a 5-year amortization schedule. Therefore, it is assumed that a $130,000 street sweeper will cost the City $26,000 per year. Other equipment, services, and training expenses were estimated and included to account for equipment and supplies such as computers, field instruments, graphic production services, and office supplies; and for costs related to employee safety and equipment operation training.

PROJECT MEMORANDUM TO: File 0E-180 (1-1.0) FROM: David Hamstra DATE: January 18, 1996 (Revised January 30, 1996) SUBJECT: STORMWATER DRAINAGE PROBLEM AREAS On Thursday, December 21, 1995, PEC (Ken Hooper, David Hamstra, and Greg Teague) attended a 10:00 a.m. presentation with Mayor Scott Vandergrift, Commissioner Scott Anderson (District 2), and City Staff (Jim Shira and Buddy Elmore). The purpose of the presentation by the Mayor was to discuss the following: • The Mayor's list of observed drainage problem areas; • Alternative methods to construct the recommended improvements; and • Recommended improvements to address water quality issues. The format of the presentation consisted of photographs of each problem area and a color exhibit depicting the approximate location of each problem area. The following is a list of pertinent topics and/or issues discussed during the meeting. 1. The Mayor began the presentation by discussing the groundwater seepage problem throughout the Amber Ridge Subdivision (PEC's Problem Area No. 8). 2. In regards to Amber Ridge, the Mayor cited a new development (The Reflections) that exhibited proper erosion and sediment control measures. Currently, the lots in The Reflections have been cleared and rough-graded. The developer/contractor has installed a strip of sod along the newly constructed roadway in order to stabilize the lots adjacent to the roadway and to prevent further erosion and possible sediment loading to the existing stormwater pond. 3. The second problem area involved roadway failure due to groundwater seepage within Forest Oaks Subdivision, specifically along the east right-of-way of Prairie Lake Boulevard, between Shummard Oaks and Sherwood Oaks Circle. The Mayor proposed the following two (2) alternatives in an effort to reduce the anticipated construction costs. It should be noted that this problem area was> engineers planners surveyors 200 East Robinson Street • Suite 1560 • Orlando, Florida 32801 • 407/422-8062 • FAX 407/849-9401 MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 2 identified in the PEC Engineering Report entitled "Stormwater Drainage Problem Areas" (dated December, 1995). First, in lieu of installing a continuous underdrain system parallel to the roadway, the Mayor suggested constructing segments "between" driveways and connect the proposed underdrain with the existing storm sewer pipe via a vertical 6 to 8-inch PVC pipe (i.e., a "tee" system). Second, the Mayor suggested to jack and bore the proposed PVC pipe under an existing driveway in lieu of removing and replacing the existing concrete driveway. The PVC pipe would then "tie-into" the proposed underdrain pipe on either side of the driveway. Ken informed the Mayor that both of these alternatives will be discussed with the contractor to evaluate the possible cost savings versus the service life of the system (e.g., the horizontal connection of the proposed underdrain and an existing inlet versus several vertical connections to the existing storm sewer pipes). 4. The next problem area involved the unnamed lake located northwest of the Sawmill Boulevard/Apopka-Vineland Road intersection (PEC's Problem Area No. 10). It was the Mayor's opinion that the County is responsible for correcting the situation since approximately 80 to 90 percent of the runoff is from unincorporated Orange County. The Mayor suggested drilling a shallow drainwell (less than 100 feet) in order to evacuate the surface water to the surficial aquifer. Ken Hooper informed the Mayor of the difficulty (if not the impossibility) of obtaining a permit from the SJRWMD and FDEP due to PEC's recent involvement with the Lake Orienta drainwell in Altamonte Springs. The Mayor offered his time to meet with the various agencies to discuss the shallow drainwell option in order to encourage aquifer recharge. Ken suggested that PEC provide the Mayor a list of names and agencies that the Mayor can contact in order to discuss the drainwell alternative. As a sidenote, the Mayor mentioned that an existing drainwell may be present based on conversations with a nearby resident and/or an employee of Kelley's Nursery. PEC will investigate this claim since unplugging an existing drainwell is more realistic than constructing a new drainwell. 5. Roadway failure due to groundwater seepage at several locations within the Sawmill Subdivision was the next problem area presented by the Mayor (PEC's Problem Area No. 19). Photographs depicted problems within the Mill Street and Lumber Jack rights-of-way. MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 3 6. The next problem area also involved roadway failure due to groundwater seepage at several locations within the Coventry Subdivision (PEC's Problem Area No. 6). Specifically, photographs depicted problems within the Essex Drive and Coventry Lane rights-of-way. As mentioned previously, the Mayor suggested the construction of underdrain segments between existing driveways and connections to existing storm sewer systems via vertical pipes. 7. The next problem area entailed the railroad bed "wash-outs" (approximately 3-4 locations) located immediately east of the Forest Oaks Subdivision (PEC's Problem Area No. 11) . The Mayor indicated that Florida Central Railroad replaced the railroad bed with additional rock, however water continues to "seep" through the rocks and onto private property of homes along Tranquille Oaks. The Mayor also noticed significant debris from the Forest Oaks residents, behind their fences and within the railroad right-of-way (e.g., grass clippings, yard waste, etc.). As a possible solution, the Mayor suggested a linear park/trail along the railroad's 60-foot right-of-way which would allow the City access to maintain the existing drainage system (i.e., remove debris and prevent excessive vegetative growth). 8. The Pioneer Key II Mobile Home Park was the next item of discussion (PEC's Problem Area No. 2). The first issue involved the existing east-west drainage ditch between the Silver Star Road Extension and the Mobile Home Park. The photographs portrayed a ditch that was not maintained as illustrated by excessive vegetative growth. Buddy explained that access to properly maintain the ditch was severely limited by the lack of right-of-way. However, with the City's recent acquisition of the Kaiser Hydraulic Excavator, maintenance should not be a problem. The second item involved the existing outfall ditch from the shopping center stormwater pond to Palm Drive. The photographs indicated poor maintenance as evidenced by a culvert under the Palm Drive Park driveway blocked by debris. Buddy informed the Mayor that the existing outfall ditch from the shopping center pond was a "private" system. The third issue involved the east-west speed bump in front of the shopping center, along the north side of the Silver Star Road Extension. Historically, the runoff south of the Silver Star Road Extension flowed north and west down the Silver Star Road Extension into the shopping center parking lot, and eventually into the shopping center stormwater pond. Since the construction of the speed bump, it was the Mayor's opinion that the surface water runoff is now MEMO TO FILE • January 18, 1996 (Revised January 30, 1996) Page 4 "redirected" into the previously mentioned east-west drainage ditch and contributes to the flow upstream of the Pioneer Key II Mobile Home Park. It is the writer's opinion that during significant storm events, runoff "jumps" the speed bump and enters the shopping center drainage system. This situation is also most likely to occur due to the lack of conveyance capacity within the subject east-west drainage ditch which results from the existing heavy vegetation. The fourth item involved the existing roadways within Pioneer Key II. The Mayor suggested that the middle portion of the asphalt roadway be removed and replaced with a concrete section. Even though the initial costs are substantially higher, it was the Mayor's opinion that in the long run, the cost would be cheaper in lieu of the on-going maintenance costs (e.g., filling in pot holes). The final issue involved the continual blockage of the internal roadway inlets within Pioneer Key II (specifically Periwinkle Key Drive). The Mayor has noticed on several occasions that during a storm event, the stormwater runoff "stacks" on top of the inlets due to blockage of the grates from debris. The Mayor suggested that in addition to improving the grate openings, that the City construct inlets along the edge of pavement to serve as overflow inlets in the likely-hood that the inlet within the middle of the roadway cannot handle the surface water runoff. Commissioner Anderson voiced his concern regarding any expenditure of City funds to correct drainage problems associated with Pioneer Key II. In fact, Scott Anderson suggested that the City purchase the lots and relocate the residents instead of "throwing good money after bad." Scott concluded his comments by stating that this development should have never been built in the first place. 9. The next problem area involved the Pioneer Key I Mobile Home Park (PEC's Problem Area No. 16). Specifically, the Mayor expressed the same concerns as Pioneer Key II with respect to inlets clogging with debris due to lack of maintenance and inadequate grate openings. Buddy informed the Mayor that an active street sweeping program would improve conditions considerably with respect to removal of debris. 10. The next subject involved the degradation of the water quality of Peach Lake. The Mayor stated that 35 years ago, the stormwater management system consisted of swales. The Mayor insisted that the City seriously consider "re- establishing" a swale system within the existing rights-of-way. Jim informed the Mayor that the existing rights-of-way are 50-foot wide, consisting of 24-foot of MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 5 pavement and 4-foot sidewalks on both sides. Therefore, there is approximately 9 feet of open space (grass) on both sides between the edge of pavement and the sidewalks in which to construct a shallow swale. David informed the Mayor that the SJRWMD would look very favorably upon vegetative swales with respect to treatment of stormwater runoff. However, the City should install concrete ribbon curbs along the edge of pavement to prevent the asphalt from "spalling" and should solicit feedback from the residents regarding a swale in their front yard. The Mayor also suggested the construction of a stormwater pond(s) between Russell Drive and Peach Lake in order to capture pollutants from the stormwater runoff. This issue is recommended in response to the Mayor's observations relative to the silt layer which has accumulated on the bottom of Peach Lake over the years. 11. The next problem area involved the intersection of Flewelling Drive and Russell Drive (PEC's Problem Area No. 3). In lieu of PEC's recommended exfiltration system, the Mayor suggested that we evaluate the use of swales in order to remove the stormwater runoff from the intersection. 12. The Center Street drainage ditch was the next problem area (PEC's Problem Area No. 5). The Mayor suggested that the City repair the "wash-out" area; lengthen the existing Center Street ditch to the west to create additional volume; and install swales upstream to reduce the amount of stormwater runoff to the Center Street ditch. Jim suggested that the City not expend any funds until a compromise can be reached with Orange County with respect to cost sharing. 13. The next problem area involved the intersection of Ocoee Hills Road and Pinewood Lane (PEC's Problem Area No. 17). Again, in lieu of PEC's recommended exfiltration system, the Mayor suggested the use of roadside swales. 14. The next problem area involved the residential area south of City Hall, west of Starke Lake, east of Bluford Avenue, and north of Lafayette Street. The existing storm sewer system that serves this area was constructed circa 1920's. The Mayor pointed out that several of the inlets are collapsed, broken, and/or clogged. Buddy informed the Mayor that a lot of these inlets are incorporated in his City-wide Roadway and Drainage Maintenance Improvements (PEC's Problem Area No. 28). MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 6 15. The Mayor suggested a proposed stormwater pond between Starke Lake and Silver Star Road (in the vicinity of the City's old beach) in order to treat the stormwater runoff from the downtown area. In addition, the Mayor also suggested a series of dams within the City Hall ditch, between Bluford Avenue and Lakeshore Drive, in order to detain (slow down) and treat the stormwater runoff. Both of these suggestions will be evaluated by PEC as part of the Starke Lake/Lake Olympia Drainage Basin Study (Work Order No. 8). 16. The next problem area involved the localized flooding along Lakeshore Drive, near City Hall (PEC's Problem Area No. 24). The Mayor suggested a collector/trunk line for conveying flow from the downspouts and redirecting the discharge into the City Hall stormwater pond. The Mayor also suggested relocating the sidewalk near Lakeshore Drive and creating efficient open space to construct a stormwater pond (e.g., urban wetland/wet detention pond). Buddy and Jim stated that they believe some of the problems (e.g., ponding of water) along Lakeshore Drive can be attributed to muck below the existing roadway, whereby the road has slowly subsided due to traffic loads and inadequate soil compaction. 17. The next problem area involved runoff from West Avenue, Spring Street, Hill Avenue, and Orange Avenue towards Silver Star Road and eventually into Starke Lake. The Mayor suggested/recommended three (3) types of improvements. First, to establish swales upstream of the previously referenced streets in an effort to "slow down" the stormwater runoff. Second, to redirect the existing flumes from the inlets into the existing swales along Silver Star Road (e.g. the intersection of Spring Street and Silver Star Road). Third, to construct stormwater ponds within the open space between Silver Star Road and Starke Lake. 18. The last problem area involved localized flooding at the intersection of Doreen Avenue and Lady Avenue. This area was not identified in the PEC report and will be investigated as a possible Phase I improvement. 19. With respect to Dovetail Court (PEC's Problem Area No. 1), David assured the Mayor that the proposed improvements would incorporate a swale along the rear lot lines in order to convey the runoff (surface water) from the north. MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 7 20. The Mayor concluded his presentation with a ranldng of his priority problems, which include the following: • Pioneer Key II (upgrade/install inlets); • Pioneer Key I (upgrade/install inlets); • Forest Oaks; • Russell Drive and Kimbell Drive (roadside swales); and • Dovetail Court. In summary, of all the problem areas identified by the Mayor, all are addressed by PEC either in the Drainage Problem Area Report or the Basin Studies with the exception of the following three (3) areas: • Forest Oaks Subdivision - groundwater seepage along Prairie Lake Boulevard; • Kimbell Drive and Russell Drive swales; and • • Localized flooding at Doreen Avenue and Lady Avenue. These three (3) areas will be investigated and possibly included into the Capital Improvement Program. With respect to construction methods and/or techniques to reduce costs, PEC and City Staff will coordinate closely with the contractors to evaluate cost effective alternatives, specifically with respect to underdrain systems. TASKS TO BE COMPLETED 1. Investigate whether a drainage well exists in the vicinity of the unnamed lake northwest of Sawmill Boulevard and Apopka-Vineland Road. 2. Investigate the previously referenced three (3) new problem areas. The week of January 22, 1996, PEC (Andrea Gwinn) inspected the new problem areas (No. 29, 30 and 31) and developed recommended improvements and the associated construction costs. 3. Provide the Mayor a list of names with SJRWMD and FDEP involved with permitting drainwell modifications and/or construction.

CITY OF OCOEE - WATER MASTER PLAN SUMMARY The City of Ocoee is the fastest growing area in west Orange County, resulting in a need for on-going potable water system management and planning. The purpose of this report is to provide a cost-effective Water Master Plan that will allow the City to continue to provide a safe and reliable supply of potable water through the year 2014. The City's three (3) existing water plants, Jamela, Forest Oaks and South Water Treatment Plants (WTP) provide potable water for the City of Ocoee. Due to the deteriorated condition and high maintenance requirements of the Jamela WTP, PEC recommends the Jamela plant be removed from service within two years. The potable water demand will increase at the existing Forest Oaks and South WTP's when the Jamela WTP is taken out of service. Existing population within the City's water service area is estimated at approximately 17,500 people based upon updated socio-economic data established for recent DRI traffic modeling and road impact fee modeling. Transportation data has been used to estimate the projected 2014 population of approximately 40,000 people. Based on the projected population increase, the City is anticipated to add 400 Equivalent Residential Connectors (ERUs) per year. Due to the varied topography of the City's water service area, the existing water distribution system has been valved off to create two separate water distribution systems, a north and south system. Future average daily water demands have been estimated by using the future projected population data plus the existing average per capita water demand for the north and south distribution systems. The flow characteristics of the existing water distribution system were evaluated by using a calibrated Cybernet computer model. Computer simulation models were performed to determine required WTP and water distribution system improvements for estimated average day, maximum day, peak hour and maximum day with fire flow. The computer simulations were developed for two WTP's in 2014. Required improvements have been divided into three phases. The first phase improvements are required before the existing Jamela WTP is taken out of service (within two years). The second phase improvements are required for new development in currently undeveloped areas. The third phase improvements are required to provide adequate capacity for estimated 2014 flows. Estimated costs for the three phases of improvements are as follows: F:\...\OE.SUM -1- 0E-215/1.0(2/01/96) engineers planners surveyors 200 East Robinson Street • Suite 1560 • Orlando, Florida 32801 • 407/422-8062 • FAX 407/849-9401 r Phase Description Estimated Costs I Forest Oaks WTP $ 603,000 South WTP $ 649,000 Dist.

F:\...\OE.SUM -2- OE-215/1.0(2/01/96) Reuse Feasibility Study Why is the City interested in Reclaimed Water, or "Reuse?" A. Disposal facilities for wastewater effluent are limited. The Florida Department of Environmental Protection encourages the disposal of wastewater through the distribution of reclaimed water because it is highly treated and is a safe and environmentally sound method of disposal. B. Many nearby municipalities, such as Altamonte Springs and Seminole County, have implemented reuse because it is a useful resource that conserves valuable drinking water. II. What is a Reuse Feasibility Report? The Florida Department of Environmental Protection requires all applicants constructing reclaimed water systems to provide this report to show the proposed reclaimed water system and to demonstrate the ability of the applicant to construct and utilize the facility. III. Does the City currently have a reclaimed water system? Yes. The city currently disposes the majority of its wastewater effluent through reuse. The city-owned Forest Lake Golf Course presently is irrigated at night with reuse. IV. What is the proposed reclaimed water system? The proposed reclaimed water system contains a total of 33 sites, which will use reclaimed water to irrigate landscaping. These sites are divided into four phases. 1. Phase I consists of serving a total of 16 sites which will receive 537,500 gallons per day of reclaimed water in addition to the current disposal of 879,800 to the golf course. The first two sites to receive reuse of the 16 sites will be the West Oaks Mall, which is currently under construction, and Orlando Memorial Gardens, a cemetery located adjacent to the north side of Forest Lake Golf Course. The other 14 sites will receive reuse as they are developed. (Refer to Map.) 2. Phase II consists of serving an additional three sites along the Clarke Road extension, which will receive an additional 430,200 gallons per day of reclaimed water. (Refer to Map.) 3. Phase III incorporates an additional 14 sites surrounding the Forest Lake Golf Course which will use 1,261,000 gallons per day of reclaimed water. (Refer to Map.) 4. Phase IV will retrofit existing residential subdivisions which will connect to reclaimed water lines constructed during Phases I and II. The estimated consumption, in addition to the 3,108,500 gallons per day of reclaimed water used through existing facilities and Phases I, II, and III, is 460,400 gallons per day for Phase VI. The total estimated reclaimed water discharge to the system is 3,568,900 gallons per day which exceeds the flow capacity of the wastewater treatment plant. V. What are the costs associated with the reclaimed water distribution system? A. Phase I - Costs not yet determined. B. Phase II - Costs not yet determined. C. Phase III - Costs not yet determined. D. Phase IV - Costs not yet determined. VI. What is the implementation schedule for the reclaimed water system? A proposed implementation schedule is attached for Phase I of the reclaimed water system. Phases II, III and IV will be constructed as reclaimed water becomes available (i.e., wastewater flows increase). VII. By constructing a reuse system, the City of Ocoee is promoting conservation of one of Florida's most precious commodities, drinking water. By irrigating with reclaimed water, potable water is not used for irrigating high maintenance landscaping and water is recharged into the groundwater system, making it available for future use. i • to) 1.4 0.

PEC PROFESSIONAL ENGINEERING CONSULTANTS, INC. MEMORANDUM TO: James W. Shira, P.E. City Engineer/Utilities Director FROM: Ken Hooper 01�"t Project Director/PEC DATE: January 31, 1996 SUBJECT: White Road Improvements The City of Ocoee authorized PEC to prepare engineering plans, specifications and permit applications for the White Road improvements west of Clarke Road. The improvements include construction of a three(3)lane typical section approximately 2,500 feet west of the Clarke Road/White Road intersections. Improvements also include the reduction in curvature north of the existing sinkhole located approximately 1,200 feet west of the Clarke Road/White Road intersections. The construction budget for completion of the roadway improvement project is very constrained and the schedule for completion of the roadway project is defined in the existing development orders for Lake Lotta Center and the Mall. In order to facilitate the schedule, PEC agreed to "fast-track" the design and provide final plans and specifications by December 31, 1995. Plans were presented December 30, 1995. As discussed, PEC coordinated with Homart to include the White Road construction with the Mall's off-site roadway improvements. The bidding of the White Road project with the Mall off-site roadway improvements should provide the City with a cost savings and provide the public with a better coordinated construction project. The maintenance of traffic issue certainly will be handled better by one contractor than multiple contracts. Homart obtained competitive bids for the off-site roadway improvements and the City's White Road improvements. C.A. Meyer is the apparent low-bidder. The cost for the White Road project is $646,215.54 and final completion is scheduled by October 1996. This is approximately $250,000 below the construction estimate. As you know, the City received $500,000 from Lake Lotta Center and the Mall to apply to the White Road project. The City's expenditure is estimated to be $146,215.54 which is a major savings for the City. engineers planners J-) surveyors 200 East Robinson Street • Suite 1560 • Orlando, Florida 32801 • 407/422-8062 • FAX 407/849-9401 MEMO TO JAMES W.

F:\cler\env\oe\oe-242\004p.ltr - PEC PROFESSIONAL ENGINEERING CONSULTANTS, INC. FEB ' 2 PROJECT MEMORANDUM TO: File 0E-180 (1-1.0) FROM: David Hamstra(10 DATE: January 18, 1996 (Revised January 30, 1996) SUBJECT: STORMtiVATER DRALVAGE PROBLEM AREAS On Thursday, December 21, 1995, PEC (Ken Hooper, David Hamstra, and Greg Teague) attended a 10:00 a.m. presentation with Mayor Scott Vandergrift, Commissioner Scott Anderson (District 2), and City Staff (Jim Shira and Buddy Elmore). The purpose of the presentation by the Mayor was to discuss the following: • The Mayor's list of observed drainage problem areas; • Alternative methods to construct the recommended improvements; and • Recommended improvements to address water quality issues. The format of the presentation consisted of photographs of each problem area and a color exhibit depicting the approximate location of each problem area. The following is a list of pertinent topics and/or issues discussed during the meeting. 1. The Mayor began the presentation by discussing the groundwater seepage problem throughout the Amber Ridge Subdivision (PEC's Problem Area No. 8). 2. In regards to Amber Ridge, the Mayor cited a new development (The Reflections) that exhibited proper erosion and sediment control measures. Currently, the lots in The Reflections have been cleared and rough-graded. The developer/contractor has installed a strip of sod along the newly constructed roadway in order to stabilize the lots adjacent to the roadway and to prevent further erosion and possible sediment loading to the existing stormwater pond. 3. The second problem area involved roadway failure due to groundwater seepage within Forest Oaks Subdivision, specifically along the east right-of-way of Prairie Lake Boulevard, between Shummard Oaks and Sherwood Oaks Circle. The Mayor proposed the following two (2) alternatives in an effort to reduce the anticipated construction costs. It should be noted that this problem area was not engineers planners surieycrs 200 East Robinson Street • Suite 1560 • Orlando, Florida 32801 • 407/422-8062 • FAX 407/849-9401 MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 2 identified in the PEC Engineering Report entitled "Stormwater Drainage Problem Areas" (dated December, 1995). First, in lieu of installing a continuous underdrain system parallel to the roadway, the Mayor suggested constructing segments "between" driveways and connect the proposed underdrain with the existing storm sewer pipe via a vertical 6 to 8-inch PVC pipe (i.e., a "tee" system). Second, the Mayor suggested to jack and bore the proposed PVC pipe under an existing driveway in lieu of removing and replacing the existing concrete driveway. The PVC pipe would then "tie-into" the proposed underdrain pipe on either side of the driveway. Ken informed the Mayor that both of these alternatives will be discussed with the contractor to evaluate the possible cost savings versus the service life of the system (e.g., the horizontal connection of the proposed underdrain and an existing inlet versus several vertical connections to the existing storm sewer pipes). 4. The next problem area involved the unnamed lake located northwest of the Sawmill Boulevard/Apopka-Vineland Road intersection (PEC's Problem Area No. 10). It was the Mayor's opinion that the County is responsible for correcting the situation since approximately 80 to 90 percent of the runoff is from unincorporated Orange County. The Mayor suggested drilling a shallow drainwell (less than 100 feet) in order to evacuate the surface water to the surficial aquifer. Ken Hooper informed the Mayor of the difficulty (if not the impossibility) of obtaining a permit from the SJRWMD and FDEP due to PEC's recent involvement with the Lake Orienta drainwell in Altamonte Springs. The Mayor offered his time to meet with the various agencies to discuss the shallow drainwell option in order to encourage aquifer recharge. Ken suggested that PEC provide the Mayor a list of names and agencies that the Mayor can contact in order to discuss the drainwell alternative. As a sidenote, the Mayor mentioned that an existing drainwell may be present based on conversations with a nearby resident and/or an employee of Kelley's Nursery. PEC will investigate this claim since unplugging an existing drainwell is more realistic than constructing a new drainwell. 5. Roadway failure due to groundwater seepage at several locations within the Sawmill Subdivision was the next problem area presented by the Mayor (PEC's Problem Area No. 19). Photographs depicted problems within the Mill Street and Lumber Jack rights-of-way. MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 3 6. The next problem area also involved roadway failure due to groundwater seepage at several locations within the Coventry Subdivision (PEC's Problem Area No. 6). Specifically, photographs depicted problems within the Essex Drive and Coventry Lane rights-of-way. As mentioned previously, the Mayor suggested the construction of underdrain segments between existing driveways and connections to existing storm sewer systems via vertical pipes. 7. The next problem area entailed the railroad bed "wash-outs" (approximately 3-4 locations) located immediately east of the Forest Oaks Subdivision (PEC's Problem Area No. 11) . The Mayor indicated that Florida Central Railroad replaced the railroad bed with additional rock, however water continues to "seep" through the rocks and onto private property of homes along Tranquille Oaks. The Mayor also noticed significant debris from the Forest Oaks residents, behind their fences and within the railroad right-of-way (e.g., grass clippings, yard waste, etc.). As a possible solution, the Mayor suggested a linear park/trail along the railroad's 60-foot right-of-way which would allow the City access to maintain the existing drainage system (i.e., remove debris and prevent excessive vegetative growth). 8. The Pioneer Key II Mobile Home Park was the next item of discussion (PEC's Problem Area No. 2). The first issue involved the existing east-west drainage ditch between the Silver Star Road Extension and the Mobile Home Park. The photographs portrayed a ditch that was not maintained as illustrated by excessive vegetative growth. Buddy explained that access to properly maintain the ditch was severely limited by the lack of right-of-way. However, with the City's recent acquisition of the Kaiser Hydraulic Excavator, maintenance should not be a problem. The second item involved the existing outfall ditch from the shopping center stormwater pond to Palm Drive. The photographs indicated poor maintenance as evidenced by a culvert under the Palm Drive Park driveway blocked by debris. Buddy informed the Mayor that the existing outfall ditch from the shopping center pond was a "private" system. The third issue involved the east-west speed bump in front of the shopping center, along the north side of the Silver Star Road Extension. Historically, the runoff south of the Silver Star Road Extension flowed north and west down the Silver Star Road Extension into the shopping center parking lot, and eventually into the shopping center stormwater pond. Since the construction of the speed bump, it was the Mayor's opinion that the surface water runoff is now MEMO TO FILE • January 18, 1996 (Revised January 30, 1996) Page 4 "redirected" into the previously mentioned east-west drainage ditch and contributes to the flow upstream of the Pioneer Key II Mobile Home Park. It is the writer's opinion that during significant storm events, runoff "jumps" the speed bump and enters the shopping center drainage system. This situation is also most likely to occur due to the lack of conveyance capacity within the subject east-west drainage ditch which results from the existing heavy vegetation. The fourth item involved the existing roadways within Pioneer Key II. The Mayor suggested that the middle portion of the asphalt roadway be removed and replaced with a concrete section. Even though the initial costs are substantially higher, it was the Mayor's opinion that in the long run, the cost would be cheaper in lieu of the on-going maintenance costs (e.g., filling in pot holes). The final issue involved the continual blockage of the internal roadway inlets within Pioneer Key II (specifically Periwinkle Key Drive). The Mayor has noticed on several occasions that during a storm event, the stormwater runoff "stacks" on top of the inlets due to blockage of the grates from debris. The Mayor suggested that in addition to improving the grate openings, that the City construct inlets along the edge of pavement to serve as overflow inlets in the likely-hood that the inlet within the middle of the roadway cannot handle the surface water runoff. Commissioner Anderson voiced his concern regarding any expenditure of City funds to correct drainage problems associated with Pioneer Key II. In fact, Scott Anderson suggested that the City purchase the lots and relocate the residents instead of "throwing good money after bad." Scott concluded his comments by stating that this development should have never been built in the first place. 9. The next problem area involved the Pioneer Key I Mobile Home Park (PEC's Problem Area No. 16). Specifically, the Mayor expressed the same concerns as Pioneer Key II with respect to inlets clogging with debris due to lack of maintenance and inadequate grate openings. Buddy informed the Mayor that an active street sweeping program would improve conditions considerably with respect to removal of debris. 10. The next subject involved the degradation of the water quality of Peach Lake. The Mayor stated that 35 years ago, the stormwater management system consisted of swales. The Mayor insisted that the City seriously consider "re- establishing" a swale system within the existing rights-of-way. Jim informed the Mayor that the existing rights-of-way are 50-foot wide, consisting of 24-foot of MEMO TO FILE • January 18, 1996 (Revised January 30, 1996) Page 5 pavement and 4-foot sidewalks on both sides. Therefore, there is approximately 9 feet of open space (grass) on both sides between the edge of pavement and the sidewalks in which to construct a shallow swale. David informed the Mayor that the SJRWIVID would look very favorably upon vegetative swales with respect to treatment of stormwater runoff. However, the City should install concrete ribbon curbs along the edge of pavement to prevent the asphalt from "spalling" and should solicit feedback from the residents regarding a swale in their front yard. The Mayor also suggested the construction of a stormwater pond(s) between Russell Drive and Peach Lake in order to capture pollutants from the stormwater runoff. This issue is recommended in response to the Mayor's observations relative to the silt layer which has accumulated on the bottom of Peach Lake over the years. 11. The next problem area involved the intersection of Flewelling Drive and Russell Drive (PEC's Problem Area No. 3). In lieu of PEC's recommended exfiltration system, the Mayor suggested that we evaluate the use of swales in order to remove the stormwater runoff from the intersection. 12. The Center Street drainage ditch was the next problem area (PEC's Problem Area No. 5). The Mayor suggested that the City repair the "wash-out" area; lengthen the existing Center Street ditch to the west to create additional volume; and install swales upstream to reduce the amount of stormwater runoff to the Center Street ditch. Jim suggested that the City not expend any funds until a compromise can be reached with Orange County with respect to cost sharing. 13. The next problem area involved the intersection of Ocoee Hills Road and Pinewood Lane (PEC's Problem Area No. 17). Again, in lieu of PEC's recommended exfiltration system, the Mayor suggested the use of roadside swales. 14. The next problem area involved the residential area south of City Hall, west of Starke Lake, east of Bluford Avenue, and north of Lafayette Street. The existing storm sewer system that serves this area was constructed circa 1920's. The Mayor pointed out that several of the inlets are collapsed, broken, and/or clogged. Buddy informed the Mayor that a lot of these inlets are incorporated in his City-wide Roadway and Drainage Maintenance Improvements (PEC's Problem Area No. 28). MEMO TO FILE • January 18, 1996 (Revised January 30, 1996) Page 6 15. The Mayor suggested a proposed stormwater pond between Starke Lake and Silver Star Road (in the vicinity of the City's old beach) in order to treat the stormwater runoff from the downtown area. In addition, the Mayor also suggested a series of darns within the City Hall ditch, between Bluford Avenue and Lakeshore Drive, in order to detain (slow down) and treat the stormwater runoff. Both of these suggestions will be evaluated by PEC as part of the Starke Lake/Lake Olympia Drainage Basin Study (Work Order No. 8). 16. The next problem area involved the localized flooding along Lakeshore Drive, near City Hall (PEC's Problem Area No. 24). The Mayor suggested a collector/trunk line for conveying flow from the downspouts and redirecting the discharge into the City Hall stormwater pond. The Mayor also suggested relocating the sidewalk near Lakeshore Drive and creating efficient open space to construct a stormwater pond (e.g., urban wetland/wet detention pond). Buddy and Jim stated that they believe some of the problems (e.g., ponding of water) along Lakeshore Drive can be attributed to muck below the existing roadway, whereby the road has slowly subsided due to traffic loads and inadequate soil compaction. 17. The next problem area involved runoff from West Avenue, Spring Street, Hill Avenue, and Orange Avenue towards Silver Star Road and eventually into Starke Lake. The Mayor suggested/recommended three (3) types of improvements. First, to establish swales upstream of the previously referenced streets in an effort to "slow down" the stormwater runoff. Second, to redirect the existing flumes from the inlets into the existing swales along Silver Star Road (e.g. the intersection of Spring Street and Silver Star Road). Third, to construct stormwater ponds within the open space between Silver Star Road and Starke Lake. 18. The last problem area involved localized flooding at the intersection of Doreen Avenue and Lady Avenue. This area was not identified in the PEC report and will be investigated as a possible Phase I improvement. 19. With respect to Dovetail Court (PEC's Problem Area No. 1), David assured the Mayor that the proposed improvements would incorporate a swale along the rear lot lines in order to convey the runoff (surface water) from the north. MEMO TO FILE January 18, 1996 (Revised January 30, 1996) Page 7 20. The Mayor concluded his presentation with a ranking of his priority problems, which include the following: • Pioneer Key II (upgrade/install inlets); • Pioneer Key I (upgrade/install inlets); • Forest Oaks; • Russell Drive and Kimbell Drive (roadside swales); and • Dovetail Court. In summary, of all the problem areas identified by the Mayor, all are addressed by PEC either in the Drainage Problem Area Report or the Basin Studies with the exception of the following three (3) areas: • Forest Oaks Subdivision - groundwater seepage along Prairie Lake Boulevard; • Kimbell Drive and Russell Drive swales; and • Localized flooding at Doreen Avenue and Lady Avenue. These three (3) areas will be investigated and possibly included into the Capital Improvement Program. With respect to construction methods and/or techniques to reduce costs, PEC and City Staff will coordinate closely with the contractors to evaluate cost effective alternatives, specifically with respect to underdrain systems. TASKS TO BE COMPLETED 1. Investigate whether a drainage well exists in the vicinity of the unnamed lake northwest of Sawmill Boulevard and Apopka-Vineland Road. 2. Investigate the previously referenced three (3) new problem areas. The week of January 22, 1996, PEC (Andrea Gwinn) inspected the new problem areas (No. 29, 30 and 31) and developed recommended improvements and the associated construction costs. 3. Provide the Mayor a list of names with SJRWMD and FDEP involved with permitting drainwell modifications and/or construction.

I . E Reuse Feasibility Study I. Does the City currently have a reclaimed water system? Yes. The city currently disposes the majority of its wastewater effluent through reuse. The city-owned Forest Lake Golf Course presently is irrigated at night with reuse. II. Why is the City interested in Reclaimed Water, or "Reuse?" A. The Florida Department of Environmental Protection (FDEP) and St. Johns River Water Management District (SJRWMD)promote the disposal of wastewater through the distribution of reclaimed water by limiting areas to discharge wastewater effluent and by limiting drinking water permits if wastewater effluent is not diposed of through reuse. FDEP, SJRWMD, and the City recognize that reclaimed water is highly treated and is a safe and environmentally sound method of disposal. B. Many nearby municipalities, such as Altamonte Springs and Seminole County, have implemented reuse because it is a useful resource that conserves valuable drinking water. III. What is a Reuse Feasibility Report? The Florida Department of Environmental Protection requires all applicants constructing reclaimed water systems to provide this report as the first step of obtaining a reclaimed water system construction permit. IV. What is the proposed reclaimed water system? The proposed reclaimed water system contains a total of 33 sites, which will use reclaimed water to irrigate landscaping. These sites are divided into four phases. 1. Phase I consists of serving a total of 16 sites which will receive 537,500 gallons per day of reclaimed water in addition to the current disposal of 879,800 to the golf course. The first three sites to receive reuse of the 16 sites will be the West Oaks Mall, which is currently under construction, Orlando Memorial Gardens, a cemetery located adjacent to the north side of Forest Lake Golf Course, and the Clarke Road median. The other 13 sites will receive reuse as they are developed. (Refer to Map.) 2. Phase II consists of serving an additional three sites along the Clarke Road extension, which will receive an additional 430,200 gallons per day of reclaimed water. (Refer to Map.) 3. Phase III incorporates an additional 14 sites surrounding the Forest F:\...\0E-245\PRESENTA 1 (02/06/96) Lake Golf Course which will use 1,261,000 gallons per day of reclaimed water. (Refer to Map.) 4. Phase IV will retrofit existing residential subdivisions which will connect to reclaimed water lines constructed during Phases I and II. The estimated consumption, in addition to the 3,108,500 gallons per day of reclaimed water used through existing facilities and Phases I, II, and III, is 460,400 gallons per day for Phase VI. The total estimated reclaimed water discharge to the system is 3,568,900 gallons per day which exceeds the flow capacity of the wastewater treatment plant. V. What are the costs associated with the reclaimed water distribution system? A. Phase I - $ 1,379,400 B. Phase II - $ 831,500 C. Phase III - $ 3,199,600 D. Phase IV - $ 2,757,700 VI. What is the implementation schedule for the reclaimed water system? A proposed implementation schedule has been developed for Phase I of the reclaimed water system. Phases II, III and IV will be constructed as reclaimed water becomes available (i.e., wastewater flows increase). Task Schedule A. Reuse Feasibility Study October 1995 - March 1996 B. Preliminary Design April 1996 - May 1996 C. City Review June 1996 D. Final Design July 1996 - October 1996 E. Bidding and Award November 1996 - December 1996 F. Construction Administration January 1997 - September 1997 VII. By constructing a reuse system, the City of Ocoee is promoting conservation of one of Florida's most precious commodities, drinking water. By irrigating with reclaimed water, potable water is not used for irrigating high maintenance landscaping and water is recharged into the groundwater system, making it available for future use.
