Miller, Assistant Director/ Environmental; Colleen Downey, Countryside High School, W. C. Baker, Director of Pubic Works, and Viola wasilewski (Recording Secretary) The meeting was called to order at 4:05 P.M. by Chairman, Bill Jonson, in the DRC Conference Room at the city Hall Annex on April 17, 1991. Motion was made to approve minutes anmd seconded. Motion carried unanimously. Mr. Tom Miller presented committee members a copy of the City of Clearwater Project status Report. The committee decided to review the report and have a discussion on it at the next meeting. Mr. DeBlaker made a motion that the Committee to the City commissionors to expediate the Environmental personnel as soon as possible. Passed unanimously. make recommendations hiring of allocated Mr. Foley seconded. It was agreed that Mr. Tom Miller would draft a letter to the commissionors and City Manager stating that the detaining of hiring additional environmental personnel, would delay the proposed environmental programs critical to the City. Mr. Tom Miller made reference to last months meeting where a discussion took place regarding area high school and college students from local schools, participating with the Environmental Advisory Committee. Mr. Miller spoke to Mr. E. Evans, principal of Clearwater High School, who was in support of this concept. ., '1 , j . . .' . :. , . I. . . . ' ..' . . , ' ".^" ,"(!. '",: ....:., Mr. Tom Miller then introduced Miss Colleen Downey, teacher from Countryside High School. Miss Colleen stated that the high school has 60-75 members in their IIEarth Effects" Club. Some of the students are highly motivated and with great ideas. Miss Colleen spoke about sone of the programs at the school such as an arboretum, creating a wildlife habitat in front of the school and a recycling center with full drop-off service. Mr. Jonson encouraged them to have an ex officio member on the committee. Mr. Tom Miller stated that these activites should start next school year. Mr. Miller distributed a memo from city Clerks office in reference to Advisory Board Lunches. Stevenson Creek Subcommittee Report Mr. Foley stated he received a memo from TOlll Burke of COM in reference to additional modeling of the "Natural Plan". Mr. Foley presented a copy of his memorandum to Committee members with the sub committe comments modifying Mr. Burke's nemorandum. The intent is to maintain wetlands in vegetated areas, and there are no objections to walls outside of wetland area. Also stated that along the channel right-of-way 4: 1 sideslopes should be constructed. A lengthly discussion followed. A modification was made in the UNatural Plan" memo article #1.3 to read "All channel improvements will be constructed within the limits of the access easement while retaining a minilllum 8' access lane on one side." A motion was made by Mr. Hunt and seconded by Mr. Reuter to have the City do the model. All in favor passed unanimously. The cost of running the model would be $3,000 to $5,000 per run. Discussion was held on having the minimum run on models. It was mentioned that the purpose of the comlllittee was to come up with the best "Natural Plan". Chairman noted that Palmetto, Drew, Cleveland and Pierce street were all part of Phase I. Reclaimed Water Master Plan Mr. Baker stated that the new advanced treatlllent process by our Waste Treatment Plants have made the wastewater into quality water and thereby made it into a commodity. It can he sold and used for irrigation purposes instead of using our diminishing potable water supply. The City wants to have a reclaillled water supply system for the people of Clearwater. Mr. Baker presented that different phases the city has planned, e~plaining all three phases and areas covered. Phase I would beg in in the Countryside area. Costs would be funded from the State Department Loan Fund. Mr. Baker explained how the system would pay for itself eventually. 2 &.."". r'4 "ii.!> ~' Reclaimed water would sell for less than the same amount of potable water. Mr. Baker explained the different options of charging citizens for this water and the savings in not using potable water for irrigation. Mr. Hunt inquired whether this was plan was authorized. Mr. Baker stated that the master plan was prepared and application has been made to DER for funding monies. Engineers have been engaged to get permits. Also exploring the Reverse Osmosis, treating brackish (salt) water. Mr. Miller requested that the time of meetings to be changed from 3:00 P.M. to 4:00 p.m. Mr. Miller indicated that this time routine conflicted with Departmental Staff Meetings. The Committee agreed. Next meeting was scheduled for April 17, 1991 at 4:00. Mr. DeBlaker made motion to adjourn meeting, Mr. Perry seconded. Meeting adjourned at .:55 P.M.

I I I I ! . I ! I I The characteristics of a "Natural Plan" are to be incorporated into a computer model of Stevenson Creek to simulate the hydraulic performance of a primarily natural channel relative to flood protection and environmental aspects during a 2S-year storm. CQ~men!s_~ng_Di~~~s~ioD 1.0 - Q~!!~!:~l 1.1 - Bridges throughout the system are to be sized so that the flow of water under normal conditions and in a storm event is not restricted for velocities at the top of bank of up to 4 Eeet per second, and Eor safe traEfic concerns. 1.2 - Achieve a 4:1 vegetated sideslops wherever possible. Vegetation selected is to be of approved native species that will provide bank stability, nutrient uptake, habitat. aesthetic value, relatively low maintenance and will not restrict the flow of storm waters. The engineering approach to altering streams must also take into account t~e importance of riparian vegetation adjacent to the stream which may control many biologically important channel characteristics. Undesirable vegetation is to be replaced by approved desirable vegetation. 1.3 - All channel improvements will be constructed within the limits of city-owned right-Of-way (ROW) using all of the RO~ where necessary with no requirement for a maintenance easement along channel side. Maintenance of the channel will be done from boats which is a normal aquatic maintenance method. Maintenance workers must be properly trained in how to maintain aquatic vegetation to avoid the practice of indiscriminate cutting and spraying. " . ' . .' . ". ..;" ~ . ~' " . . . . ...., . . .. '.

North of the Drew st. bridge (in Clearwater Country Club) remove existing broken concrete. Transition channel top width to meet bridge width. On both north and south sides of Drew St. bridge vertical concrete sidewalls above the wetland area are acceptable for 100' ~/- transition to vegetated channel. Sideslopes of 4:1 are to be used for the v~gatated channel. (Sea 1.1, 1.2, 1.3) Cleveland St. to Drew St. Clean up transition area north of Cleveland St. bridge. Construct a sediment trap on the Shooter Shack property (City property) for Cleveland Street storm pipes on east side of stream. Use 4:1 vegetated sideslope up to maximum ROW. Protect trees from encroachment of sideslope. If easement permits widen west bank of channel just north of Cleveland St. bridge and allow use of vertical concrete wall for 200' +/- along west side of channel north of bridge above wetland area. (See 1.1, 1.2, 1.3) Pierce St. to Cleveland St. Existing vertical concrete walls and earthen bottom may remain unless ROW will permit removal and replacement with 4:1 vegetated sideslopes. Consider acquisition of vacant Morrison Cafeteria site for construction of a detention pond to serve storm pipe flows from west of the stream. Relocate the pipes on the sides of the Pierce St. bridge. (See 1.1, 1.2, 1.3) Franklin St. to Pierce St. Widen channel and construct 4:1 vegetated sideslopes on both ~ides of creek. Relocate pipes on both sides of Franklin St. bridge. (See 1.1, 1.2, 1.3) Court St. to Franklin St. When replacing the Court st. bridge a major consideration is the pipe under the bridge that has been ~he cause of numerous blockages in the past and must be relocated. Widen the channel section and construct 4:1 vegetated sidaslopes on both sides of creek. Consider lowering, by excavation, the ball field on east side of stream adjacent to Franklin St. to increase flOOdplain storage. (See 1.1, 1.2, 1.3) 2 {C t' ! Druid Rd. to Court St. Construct a wetland/lakes detention system in Glen Oaks (City property) using natural methods and native vegetation. Shape the system to maximize use for detention preserving as many trees as possible and to provide aesthetic benefits. Relocate existing weir from Druid Rd. to north (downstream) of Druid Road an appropriate distance from the bridge so that baCKwater affecting flows under the bridge will be minimized. yet allow for a detention pond in Glen Oaks. Consider a wider weir to reduce backwater condition. Relocate existing pipes on sides of and under the Druid Rd. bridge, which do, obstruct flow and have caused blockages in the past.

Remove the Rice Lake control weir and move it to the north side of St. Thomas Dr., constructing an appropriate control structure that will not cause stagnation and will provide for improved treatment of waters discharged to downstream locations. Replace the St.Thomas Dr. culvert~ if necessary to provide unrestricted flow up to 4' per second flow rate at top of bank. (Sea 1.1, 1.2, 1.3) ~~Q~~uli2_MQQelin8 v The purpose of this hydraulic modelins is to determine the feasibility of a natu~al channel for managing normal and storm flow conditions. Once the c.pacity of a natural channel is established any additional capacities that may be needed to manage a 2S-year storm event can be determined in the sub basins along the system. It will be possible to define the size and approximate locations of additional detention and retention systems needed to meet the full 2S-year requirement for the basin. Detention or retention ponds at the Shooter Shack, Morrison Cafeteria, Glen Oaks and excavation of the ball field along Franklin St. will have some impact on the channel capacity and will provide greatly improved water quality and natural habi tat. The proposed modeling work should accurately represent the hydraulic performance of the "Naturql Plan" as detailed by Mike Foley and Bruce Nettleton and approved by the Environmental Advisory Committee. Additionally, proposed modifications must be such that a Comprehensive Watershed Management Plan and a Stormwater Management Plan for the Stevenson Creek Basin will not be compromised or precluded, and that they may be optimized for protection of the natural surface waters, the downstream estuaries and Clearwater harbor. Additional specific comments on characteristics of the "Natural Plan" are as follows: Direct a land acquisition program as needed to ensure the conservation and protection of the resource in accordance with the SWF~MD District GOALS. Channel improvements will be those required for improved hydraulic transition. water quality benefits, protection of downstream estuarian systGms, aesthetic values, and protection and improvement of natural stream functions. The model will represent a vegetated channel between Betty Lane and Bellview Blvd., except for a minimum of structural lining to protect the bridge structures. - 4 - ~, , f ;. ~ ,t:> 'l" ( I The model will continue to incorporate a box culv~rt or pipe under Jeffords St.. sized for adequate flow rate, and may extend that structure south. under Hillcrest St. on thE west side of the stream to Browning St.. It is intended that this culvert or pipe be for the conveyancE of water in storm events only. Normal flows are not to enter this conveyance system in ord~r to sustain a wildlife corridor in the natural stream. " ' Jt!

These sources provide, for instance, that nonstructural solutions to water resource problems should take precedence. ,The Board Plan in the section titled BASIN PROFILE states: . ..the water management district concept in Florida has evolved from primarily flood control towards an integrated resource management approach. . ..water quality issues are often as important as water quantity issues. The Board Plan under WATER RESOURCE ISSUES states: Developed or developing areas which do not currently address both quality and quantity aspects of the drainage issue may benefit from additional planning and re design efforts. The Board Plan under the title MISSION AND GOALS states: Central to the mission is maintaining that balance between water needs of current and future users while protecting and maintaining the natural systems. The mission of the Pinellas Anclote River Basin Board is to assist the Governing Board of SWFWMD in managing water and related land resources. within its boundaries as authorized in Chapter 373, Florida statutes. Central to this mission is the development and implementation of non-regulatory, environmentally sound water resource programs of particular benefit to the residents of the Basin. - 5 - , ,."

The inspection was made by r.1ike Foley, Bruce' Nettleton, Tom Hiller and Tom Burke. The pUl"pose of the inspection was to identify those physical characteristics of the creek which v.'ere considered, by I'like Foley, as a representative of the city's Environmental AdvisoL'Y Committee, to be inherent to a "Natural plan" for storrnwater management. Those characteristics are to be incol"porated into a computer model of the creek to simulate the hydraulic performance of the "Natural plan" relative to flood pl"otection during a 25-year storm. Comments and Discussion A copy of the notes which I made dUl"ing the field inspection is attached hereto. Those notes are summarized as follows: Location Comments and Discussion Palmetto St. to Douglas Ave. North or Palmetto st. bridge, provide only for "restorative maintenance" (no dredging). Leave the bridge as it is. Provide for vegetative plantings as required for improved bank stabilization. Drew st. to Palmetto St. Don't change the Drew st. bridge. North of the bridge, improve channel by removing existing broken concrete and widen channel top width to match existing bridge width (30'). vertical concrete sidewalls are acceptable for 100'+/- transition to existing vegetated channel on both north and south sides of the bridge. Sideslopes no steeper than 2:1 are to be used fol" the vegetated channel. Cleveland st. to Drew st. Don't change the Cleveland St. bridge. Clean up the transition area at the south side of the bridge. Acquire the Shooter Shack and construct a small sediment trap for Cleveland St. flow. Use vertical concrete wall construction as required (200'+/-) along the west side, in the area north of the bridge. l6 Y &R) I, '. 'f . .' .'. ..,.... " . .' .' ',; . .,' .. ' ..' '.. .' I . " . .

The channel reach between Drew St. and Cleveland st. \"il,l transition from a concrete rectangular section, at the north side of Cleveland st. to a grass-lined earthen section, beginning about 200 feet dm.mstream and ending at Drew St. Channel dimensions will conform to existing Ra~ limits. o The model will continue to incorporate the proposed box culverts within the Jeffords St. right-of-way. The continued use of the existing creek north of Jeffords st. is not hydraulically significant to the model. o A grass-lined channel will be modeled in place of either the existing 5411 CHP or the proposed fabriform-lined channel betvJeen Belleview Blvd. and St. Thomas Dr. This channel will have a 30' top width and 2:1 sideslopes. o A grass-lined channel ~rill be modeled in place of the proposed fabriform-lined channel between Lakeview Rd. and Belleview Blvd. This channel will have a 30' top width and 2:1 sideslopes. o The Rice Lake weir will be replaced by the proposed labyrinth weir structure, as per the City's plan, to provide for improved treatment of waters discharged to downstream locations. The St. Thomas Dr. culverts will not be replaced, however. The proposed modeling work should reasonably represent the hydraulic performance of the "Natural Plan" as detailed by Hike Foley and Bruce Nettleton. Understand that, because the existing culverts and road crossings f~~ the ~jor hydraulic cause of local flooding problems, the proposed "Natural plan" model \-,.Ti11 probably continue to indicate extensive flooding along the Stevenson C~eek during a 25-year event. As a result, it is not likely that the proposed "Natural plan" will provide reasonable flood protection. please review this memo with the Environmental Advisory Committee and let us know if you concur \dth our understanding of the "Natural plan" and its representation as summarized above. dmc HEr.HC. 1/35 c: William C.

Hydraulic Hodeling Based on the results of the field inspection, summarized above, it is reasonable to adapt the hydraulic model for consideration of the "Natural Plan". The substantive hydraulic differences in the "Settlement Offer" and the "Natural Plan" configurations are related to considerations of the road crossings. The "Settlement Offer" anticipates substantial constructed improvements to major road crossings; the "Natural plan" anticipates no structural changes to road crossings except at Jeffords st. Relocation of the pipelines considered in the above comments is common to all alternatives, and is not a consideration of hydraulic differences be~~en the alternatives analyzed. Previous detailed consideration of the "Settlement Offer" included the LIse of the Glen Oaks Golf Course as a flood detention pond. At elevation 18.0, the golf course was modeled to provide a detention area of about 12.3 acres. Computer modeling confirmed that construction of the 12.3-acre pond would reduce the 25-year peak flow by only about five percent. Based on this limited reduction, it is considered that construction of relatively small detention ponds at the Shooter Shack and Horrisons Cafeteria sites would have negligible impact on the required channel capacity. As a result, further consideration of those sites will be not be represented in the hydraulic model, but reserved for subsequent consideration for permitting and water quality enhancement. Specific comments on the modeling characteristics of the "Natural Plan" are as folIO\>Js: o All existing bridges will remain \~ithout change except for Jeffords st. o All channel improvements v:ill be constructed \..;i thin the limits of existing city-ovmed right-of-way. .' .'

The greatest percentage of those funds anticipated for the Environmental Management Group were in support of four new positions. The Environmental Advisory Committee has had an opportunity to review the Environmental Management Group I s "Comprehensive Environmental Management Programs and Reorganization Plan of November, 1990 at the March, 1991 Committee meeting. The Committee has endorsed the prograns contained within that document and fully supports the reorganization plan as proposed. The Committee recognizes the many challenges and opportunities that are before us. The Committee also recognizes that the proverbial "clock is ticking away" with the Federal National Po'llutant Discharge Elimination System (NPDES) permits looming on the horizon. As a result of that awareness, we are concerned about present staffing l.evels in the Environmental Management Group and the rapidity with which those positions are being filled. It is the opinion of this Committee that delays to complete staffing within Environmental Management could prove critical to the full implementation of Environmental Programs for the city of Clearwater. Therefore, the Environmental Advisory Committee respectfully requests that every possible effort be made to expedite the Environmental Programs for the City and complete the recruitment of additional staff identified in the reorganization plan and approved by the Commission through the Stormwater utility Program. t'\ ;:\ V)) ,'J li'" , CLEARWATER SIGN AMORTIZATION PROGRAM In 1985, the Clear~ater City commission adopted sign regulations to improve the appearance of the Clear~ater com~unity. As part of these regulations I exist.ing signs which did not conform to the regulations will be required to be brought into compliance by October 13, 1992. This period in which nonconforming signs are allowed to remain is called an "amortization" per iad. Business owners nay have already received some notice of this amortization period 'through notices from the city IS occupational license off ice. Amortization periods for nonconforming signs are an established legal procedure. Despi te nUl1\erous legal challenges, state and federal courts (inc1uding the U. s. Supreme Court) have consistently upheld the ability of local governments to establish amortization periods. The Clearwater Planning and Development Department is nearing the completion of its inventory of nonconforming signs across the city~ Once this inventory is complete, letters will be mailed to all property owners having nonconforming signs; these letters "Will describe the type oE nonconformities and list options availab1e for property owners who wish to appeal or challenge any determination of nonconformity. A contact person will also be listed for property owners who have questions. As required by city Code, the Planning and Development stafE vill notify all property owners having signs which are currently nonconforming by mid-April of this year. This will provide an 18 month notice period to allow property owners to bring their signs into compliance with City code. , r \ ;.:, '<!2) " f'i;" -,' n' ~ " . ..t." I ~ '. .... I , " ...~: .' , ,.
