RE: [External] RE: Presley 19-0515
I received your comment. But in both cases we either have automotive pollution (from a main
roadway) being discharged directly to a stream and potential fertilizer/chemical inputs being
discharged directly to the stream. Discharging to the buffer area (not through the headwall) to
allow SW flow to discharge adjacent and alongside the channel seems to be a reasonable
request. That is minor change to the location of the outfall and overall SW plan. Or part to
the bmp and part to the buffer. Thanks

Good afternoon Alan,

Following up on the correspondence you and Dan have had recently on the extension of the existing culvert for the
Presley Residential project. To bring the overall location into scope I have attached an exhibit highlighting the drainage
area going to the proposed manhole junction which is used to align the culvert extension with the existing intermittent
stream. On the attached exhibit the red area is the total drainage area to the manhole. The total drainage area for all the
inlets that drain to the manhole is 2.35 acres with approximately 0.74 acres (0.25 acres of existing road impervious) of
that total being impervious (existing/proposed roadway and sidewalk). Considering the overall drainage area to be
relatively small and much of that area pervious, we hope to proceed with the design as currently proposed to avoid an
additional headwall outlet in the retaining wall upstream of the proposed culvert inlet and impacting the existing
streamside buffer with the installation of an energy dissipation rip rap apron. Please let us know if we can proceed with
approval of the proposed design.
Thanks,

Not sure why the stormwater cannot be discharge in into a buffer. See diagram. Not sure
where pipe 2 goes to. We aren't a fan of dumping SW directly into a stream. There was a
basically bmp location provided with the original site plan.
Thanks

Alan
