City of River Oaks, TX Stormwater Runoff Outfall Mapping

There are 16 outfall points where stormwater runoff leaves the city. Of those 16 outfall points there is established 11 outfall sampling points and 2 grab sample sites that could be used for a total of 13. Enclosed is the mapping that plots on the city’s base map those outfall points. The base map is separated into sectional outfall location maps (also enclosed) described as follows:

(1)

Stormwater base map.

(Enclosed as “Stormwater Base Outfall Map” of entire city.)

(A)

Base map.

The base map plots the 16 outfall lines where stormwater runoff would exit the city. Outfall lines are color coded RED. The main receiving drainage. channels or surface areas where stormwater runoff is received in the city are color coded GREEN. Drainage flows within the city consists of surface drainage, underground conduits and runoff through the drainage channels and ultimately all runoff outfalls to the West Fork of the Trinity River as the MS4 receiving stream. The Trinity River is located on the west, south and eastern boundaries of the city and drainage flow is primarily from the northeast to southwest throughout the city. There are outfall points where the runoff leaves River Oaks either though drainage channels or surface runoff or as a part of an underground stormwater conduit interconnecting with the City of Fort Worth drainage system.

(B)

Stormwater outfall base map.

The base map plots the main drainageways and the outfall points of the entire city. The outfall points are:

(i)

(x)

Surface drainage only from Drainage Basin WF7 in River Oaks south into Fort Worth (natural drainage flow into Fort Worth). (Any sampling would have to be a grab sample taken from the street right-of way.)

(xi)

Map 1 - WF11 (N):

This map plots the far north to northwest portion of River Oaks from Roberts Cut Off Road west to the Trinity River and north to south from the city limits to Notre Dame Avenue in the north part of Drainage Basin WF11 and includes:

4 outfall points (in RED) (#1 through 4) with 1 sampling site at Outfall Point #1 that is representative of all 4 underground stormwater conduits that receive runoff from the rear of Yale Street properties in Drainage Basin WF11, then drains west under Inspiration Lane and then at a point on private property free flows on the ground surface across the properties in a westerly direction to the West Fork of the Trinity River;

1 outfall point (#5) (in RED) and 1 sampling site at outfall point (#5) where underground stormwater conduit from Drainage Basin WF11 flows east to west on Baylor Ave. into a receiving manhole on the far west end of Baylor Avenue at the River Oaks city limits where it goes into Fort Worth;

(ii)

Map 2A - WF 7, 8 & 11 (NW x SW):

This map plots the southwestern section of Drainage Basin WF11, west side of WF7 and Drainage Basin WF8 covering the area from Notre Dame Avenue south to River Oaks Blvd.; then in a south by southwest direction from River Oaks Blvd. in Drainage Basin WF8 from Roberts Cut Off Road on the east end to Sam Calloway Road on the west end at the city limits boundary and includes:

Outfall Point #6 (in RED) is the point where drainage flow is received from surface street drainage on Meandering Road through an earthen channel located in the City of Fort Worth;

Drainage flow from Meandering Road would have to be sampled at the street inlets in the 5800 block of Meandering before entering the drainageway located north of Meandering Road in Fort Worth on property belonging to Camp Carter;

Outfall Point #7 is a combination of surface and underground conduit drainage along the north side of River Oaks Blvd. flowing from east to the west from Roberts Cut Off Road to the city limits with Fort Worth in Drainage Basin WF11 where the, drainage flow runs off into the Trinity River. (Samples representative of this outfall area would be taken from the concrete lined channel in the 5600 block of River Oaks Blvd.);

Outfall Point #8 is surface drainage along the south side of River Oaks Blvd. flowing from east to the west from Coates Drive to the city limits with Fort Worth in Drainage Basin WF11 where the drainage flow runs off into the Trinity River. (Samples representative of this outfall area would be taken from the drainageway at the city limits); Note: Drainage flow on the south side of River Oaks Blvd. is not connected to the north side of River Oaks Blvd. Both sides drainage flows are independent of each other according to the natural flows in this area. The north side receives drainage flows from the residential areas north of River Oaks Blvd. and also receives from stormwater runoff east to west on the north side of River Oaks Blvd. from Roberts Cut Off Road to the western city limits with Fort Worth. The south side flows in two different directions; first it flows from Coates Drive back east to Robert Cut Off where it interconnects with drainage flows back south on Roberts Cut Off Road to the southernmost boundary of the city, then secondly from the other side at Coates Drive the flow is on River Oaks Blvd. west to the Trinity River and the westernmost boundary of the city.

Outfall Point #9 is stormwater runoff from the drainageways in Drainage Basin WF8 from River Oaks to Fort Worth that flows north to south under Sam Calloway Road through an underground conduit and interconnects to an open earthen channel in Fort Worth that ultimately flows to the Trinity River. (Sampling point would be from the inlet on the north side of Sam Calloway Road in River Oaks);

There are 4 outfall points and 4 sampling points plotted on Map 2A. Outfall Point #5 at the top of the map on Baylor Avenue has already been included in Map 1.

(vi)

Map 4 - WF 5-6 (NE):

Area of River Oaks from the upper northeast city limits south to River Oaks Blvd. and west to east from Long Avenue to Highway 199 (Jacksboro Highway) within Drainage Basins WF5 and WF6 including Outfall Point 15 and 16 as follows:

Drainageway plotted and color coded GREEN flows north to south behind the properties in the 2600 Jacksboro Highway coming from Fort Worth on the north and exiting River Oaks on the south back into Fort Worth;

There is 1 inlet point (GREEN) at the north end (top) of the map where the drainage channel in the rear of the properties in the 2600 block of Jacksboro Highway receives stormwater runoff from Fort Worth and an outfall point (#15) (plotted in RED) where the drainageway behind the 2600 block of Jacksboro Highway in River Oaks interconnects with Fort Worth in the inlet at River Oaks Blvd. The sampling point for 15 would be from the outlet flow at River Oaks Blvd. Note: It would be necessary to sample the inlet flow and the outlet flow in order to indicate any differences in toxin levels from Fort Worth through River Oaks;

Outfall Point 16 is combination surface drainage from Hillside Drive and Hilltop Circle in River Oaks into the street inlet on the west side of Hillside Drive; then underground from the street inlet east under Hillside Drive through an underground conduit in a dedicated easement that interconnects with the drainageway in Fort Worth located behind 1509 Hillside Drive (sample point for 16 is located behind 1509 Hillside Drive where the conduit pipe discharges into Fort Worth drainageway).
