1 Project Introduction
1.1 Purpose
The purpose of the stormwater facilities located at the Fred Richards Playground (approx.
Parklawn Avenue and Nine Mile Creek Regional Trail) is to capture the stormwater runoff from
the picnic shelter and filter it before it returns to the adjacent pond or infiltrates into the
groundwater. The nearest downstream waterbody is a pond/delineated wetland on the former
Fred Richards golf course, forming one edge of the property boundary.
1.2 Manual Intent
The intent of this manual is to provide guidance for the on-going operation and maintenance of
the project components.
This manual was created so that new users are able to gain a general understanding of the system
components and will be able to address needs in the field in an expedited manner.
1.3 System Summary
1.3.1 Bioretention Basin
Water from the concrete picnic shelter pad will be collected and filtered in a bioretention basin
at the western edge of the playground area, next to the pond. The bioretention basin is 130 SF
at the bottom and 467 SF at the emergency overflow elevation. Runoff from the picnic shelter
enters the bioretention basin through a grass filter strip (see below). The interior of the
bioretention basin consists of 18” depth engineered biomedia (consisting of 80% washed sand,
10% organic leaf compost, and 10% peat). Plants and biomedia within the bioretention basin
filter stormwater before it enters the adjacent pond. Filtered water exits the bioretention basin
through a 6” drain tile at the bottom of the biomedia.
1.3.2 Grass Filter Strip
The filter swale/strip is located between the picnic shelter and the bioretention basin. It is 300
SF in area. It will collect water from the picnic shelter and concrete pad and deliver it to the
bioretention basin. The filter strip will be planted with turf and will be maintained similar to the
surrounding lawn areas.

2 Routine Inspection and Maintenance
2.1 Inspection Schedules and Maintenance Activities
Periodic inspection of the project will be somewhat on-demand and weather dependent.
Generally, each facility should be inspected on a schedule according to Table 1 below.
Maintenance activities should be performed according to Table 2 below. Prepare and maintain a
record log of all maintenance activities including inspection dates, condition of facilities and
maintenance operations performed.
Table 1. Routine Inspection Schedule
Facility Inspection Frequency
Bioretention Basin Bi-monthly (spring, summer, fall); monthly in winter
Filter Swale/Strip Bi-monthly (spring, summer, fall); monthly in winter
Table 2. Routine Maintenance Procedures
Stormwater Facility Site Maintenance
Bioretention Basin Check inlet areas for sediment deposition. Remove accumulated sediment and
debris with a shovel.
Check basin for areas of erosion, displaced mulch, and deceased plants.
Remove trash, debris and dead vegetation.
Fix areas of erosion, replace mulch and plants as needed.
Hand remove or spot treat weeds with glyphosate herbicide.
Filter Swale/Strip Remove any trash and debris in the swale as a part of routine landscape
maintenance. Remove any accumulated sediment with a shovel.
