Current Pinellas Park Water Management District Projects
The types of public facilities provided by the District include five channel systems, structures at roadway crossings, control locations (weirs), and detention/storage lakes and ponds.
Channel 1 Basin
The District Channel 1 Basin comprises approximately 2,560 acres in the northwestern portion of PPWMD. The basin lies generally west of U.S. Highway 19 between 74th Avenue and 102nd Avenue, and is drained by a channel system composed of a main channel and three primary tributaries. The tributaries include Channels 1A, 1B-5 and 1C, which all drain to the main channel.
The headwaters of Channel 1A begin at 49th Street and 80th Avenue, proceed westerly, then turn northerly before 53rd Way N., then westerly at 90th Avenue to the confluence with Channel 1 near 60th Street N. Channel 1A serves a primarily residential area, with the easterly segment bordered by 49th Street N. on the east, Park Boulevard on the south, 53rd Way N. on the west, and just south of 94th Avenue on the north. The westerly segment, also primarily residential, is bordered on the east by 53rd Way N., on the south by 84th Avenue, on the west by 59th Street N., and on the north by 94th Avenue.
Channel 1B-5, which once drained to the Channel 5 Basin, was diverted to the Channel 1 in the 1960s. Channel 1B-5 also serves a primarily residential area bordered on the east by 53rd Street N., on the south by Park Boulevard, on the west by the CSX Railroad and Channel 1, and on the north by 84th Avenue and 90th Avenue. Channel 1B-5 begins at 55th Street N., proceeds westerly to the CSX Railroad (eastern side), then northwesterly to the confluence with Channel 1. A portion of Channel 1B-5 from 58th Street to 60th Street was lined with concrete to prevent sideslope failure. The old fabriform slope stabilization system on this section of pipe had failed and repair was needed.
Channel 1C begins at 98th Avenue and 62nd Street N. and proceeds southerly to the confluence with Channel 1 adjacent to the Loyd Tingler Nature Park. Channel 1C serves a residential area bordered primarily by itself on the east, Channel 1 on the south, CSX Railroad and 66th Street N. on the west, and 102nd Avenue on the north.
The Channel 1 system flows westerly to its outfall at the Cross Bayou Canal. The channels total approximately 9.3 miles in length and bottom widths range from 2 feet to 26 feet. The Channel 1 conveyance system is composed of concrete-pave and fabriform-lined channels, grass lined reinforced earthen channels, bridges, culverts, unimproved channels, and pipe systems that are all maintained by PPWMD. The piped system and channels draining 200 acres or less are maintained by the City of Pinellas Park and Pinellas Park County.
Channel 2 Basin
The Channel 2 Basin comprises a main channel and four tributary channels 2A, 2B, 2D and 2E north of Park Boulevard and east of 49th Street, which provide drainage for approximately 2,270 acres. Channel 2 is the outfall for a city-maintained storm sewer that parallels Park Boulevard along 75th Avenue from 46th Street North to just east of U.S. Highway 19. The main channel serves the area from 82nd Avenue to Park Boulevard and east of 49th Street to Gandy Boulevard. The general flow direction is easterly until it crosses Gandy Boulevard and discharges to Sawgrass Lake.
Channel 2A drains the western half of the Mainlands of Tamarac, located east of U.S. Highway 19, and north of 90th Avenue. It also drains the residential and commercial areas located between U.S. Highway 19 and 49th Street N., north of 82nd Avenue, and the westernmost portions of Gateway Centre, and the Sunset Mobile Home Park. Channel 2A flows eastward from 49th Street N. and then south to its confluence with Channel 2 near the Sunset Mobile Home Park.
Channel 2B, located at the southwest corner of the Mainlands subdivision, serves primarily the Mainlands Village Shopping Center and the western portion of the subdivision. Channel 2B discharges to Channel 2A near 40th Street N. and 86th Avenue.
Channel 2C is part of Channel 2D, which serves as an outfall from East Lake in the Mainlands subdivision. Channel 2D and portions of Channel 2A were reconstructed through the Gateway Centre property in a joint effort between the developers of Gateway Centre and the District. Channel 2D flows easterly and discharges to Sawgrass Lake.
Channel 2E is an overflow channel that drains the northeastern portion of the Mainlands subdivision and the northern part of Gateway Centre. It flows easterly and discharges into the Roosevelt Creek drainage basin of Pinellas County.
The channels of Basin 2 total approximately 6.0 miles in length, and include grass-lined and unimproved channels, bridges, culverts, and pipe sections that are all maintained by PPWMD. The piped system and channels draining 200 acres or less are maintained by the City of Pinellas Park.
In 2006, the District performed a hydraulic analysis of the Saw grass Lake drainage basin. The results of this analysis indicated that several improvements to the Channel 2 conveyance system would lower peak flood stage evaluation significantly. The City of Pinellas Park has a capital project to make some of these improvements and the District has added two projects to this CIP.
Channel 3 Basin
The Channel 3 Basin provides drainage for the area east of 49th Street from Park Boulevard to the southeastern boundary of PPWMD. The flow is northeasterly to its point of discharge on the west side of Sawgrass Lake. The system consists of a main channel and one tributary, Channel 3A, and serves approximately 916 acres of highly urbanized drainage basin, including large areas of commercial and light industrial development. The main channel is concrete-line from 35th Street to Sawgrass Lake.
Channel 3A discharges to Channel 3 at the intersection of 67th Avenue and 37th Street N. The lower 3,640 feet of Channel 3A form a storm sewer system that serves as the outfall for a large commercial area, including the Parkside Mall. The upper reach of Channel 3A parallels 72nd Avenue and serves a primarily residential area between 49th Street N. and 41st Street N., south of Park Boulevard. The channels of Basin 3, concrete-paved and unimproved channels, and bridges total approximately 2.8 miles in length and are all maintained by PPWMD. The piped system and channels draining 200 acres or less are maintained by the City of Pinellas Park.
Channel 4 Basin
The Channel 4 Basin is located in the southwestern portion of the PPWMD and consists of the main channel; three minor tributaries: 4A, 4E, 4E-1; and the lake at 4F. The tributaries of Channel 4 and the lake 4F are maintained by the PPWMD. Other tributaries including 4B, 4C and 4D are maintained by others and are not shown on map 2. The system provides drainage for approximately 1,857 acres and flows southwesterly to its confluence with Joe’s Creek just south of 54th Avenue. The basin lies generally west of 49th Street N. between 74th Avenue N. (Park Boulevard) and 54th Avenue. The channels, including piped sections of 4E, total approximately 4.7 miles in length.
Channel 4A serves a drainage area with commercial, residential and rural properties. It I bordered on the east by the CSX Railroad, on the south by 54th Avenue, on the west by 53rd Street N. and 58th Street N. and 68th Avenue on the north. Channel 4A flows from the 62nd Avenue westerly to the confluence with Channel 4 at Debra Lake near 58th Street N.
Channels 4E and 4E-1 serve an area bordered on the east by 53rd Street N., on the south by 54th Avenue, on the west by 60th Street N. and Channel 4, and on the north by Channel 4. Channels 4E and 4E-1 flow from McKee Lake northwesterly to Channel 4 near 64th and 63rd Streets N. Channel 4F flows from 66th Avenue to Channel 4 near 64th Street N. The Channel 4 drainage facilities include concrete-paved channels, fabriform concrete channels, bridges, culverts, storm sewer systems, and unimproved channels. The District is currently evaluating improvements to Channel 4 and Channel 4E which may affect the CIP. The piped system and channels draining 200 acres or less are maintained by the City of Pinellas Park.
Channel 5 Basin
The PPWMD Channel 5 Basin is an approximate 560-acre drainage area in the central portion of Pinellas County. The basin lies generally east of 78th Street N. between 66th Avenue N. and 82nd Avenue N. and is drained by a channel system composed of a main channel. The system flows southwesterly to its outfall at Joe’s Creek and consists of unimproved channels, concrete-paved channels, articulating block-paved channels, bridges, culverts, approximately 1.4 miles in length that are maintained by PPWMD. The piped storm sewer system, piped sections, and channels draining 200 acres or less are maintained by others.
