Mr. Rick Martin
3456 Watermark Ct.
Springfield, OR 97478
Dear Mr. Martin:
This letter is concerning your construction project at 3456 Watermark Ct. You
have requested specific direction regarding drainage requirements at the north
side of your property. The property must be graded so that your site does not
drain onto the neighboring properties to the north, east or west. A 12-inch public
storm sewer line is located along your north property line in a public utility
easement. The Public Works Department has granted you permission to locate
an area drain or catch basin within the P.U.E. as long as you adhere to the
following:
1. The area drain or catch basin must be positioned so it is not
located directly over the public storm sewer line.
2. You must obtain an Encroachment Permit from the Public Works
Department to core drill and tap into the 12-inch storm sewer with
the outflow pipe from your basin. An application form for the permit
is enclcosed for your convenience. Please contact Ron Sather,
Public Works Construction lnspector, (726-2240) with questions
regarding the permit or connection requirements.
3. The catch basin larea drain enclosure must be watertight and shall
be adequately sized to accept the water runoff from your site with
an approved child-proof grate cover. The basin may be of
concrete, metal or plastic, as appropriate. lf the area of the
property being drained to the basin is greater than 5000 s.f., a
double compartment basin must be used.
4. The outflow pipe in the basin shall have a turned-down collection
orifice (ell) to minimize the amount of floating material that will enter
the system.
5. The bottom of the basin shall be at least 18-inches below the
outflow collection orifice.
6. We recommend that a 12inch wide concrete mowing strip be
installed around the rim of the basin for easy maintenance and to
minimize the amount of debris getting into the basin..
7. The City Plumbing lnspector shall inspect installation of the catch
basin and outflow line. The sewer tap will require inspection by a
Public Works Construction or Maintenance lnspector.
Please note that all areas of the site must drain to an approve drainage
way. The grade around the building must drain away from the building on
all sides. Any sumps created by backfilling around the home must be
eliminated, i.e. under the deck.
I trust the above information will be sufficient to enable you to proceed with the
drainage work. The drainage system must be completed before we can grant
final occupancy approval for your new home.
Sincerely,
Donald re
