Dear Mr. Croy:
SUBJECT: BASEMENT SEEPAGE *A_.�_�___BiRCH,_ STREET---. I
Enclosed is information regarding subsurface drain con-
struction from Bob Franklin, Storm -Water Managem . ent Engineer
for the City.
Enclosure 1 is from the Engineering Field Manual published
bv the U.S. Soil Conservation Service. Filters are needed
t� prevent clogging of subsurface drains. The enclosure describes
the filter material.
Enclosure 2 is a detail of an interceptor tr*ench. Note
that the filter material is also to be used with this facility.
Both drains and interceptor trenches have perforated pipes
which must be connected to a suitable outflow. Connection
can be made to the City's catch basin adjacent to your property
(proper permits must be obtained and procedure-s followed).'
Please keep us informed of the work on the subject problem
and call if we can be of any further assistance.

ENVELOPES AND FILTERS
Sand and Gravel Envelopes
�: K*ft) 11 L=7 - I
The basic functions of an envelope are to provide a -bedding for the
drain.and'.to,iniprove the permeability in the zone around the drain. The
main requirement of the ma'terial in the envelope is that it have a per-
meab'ility higher than the base material. The maximum size of the envelope
materia * 1 should not be greater than 112 inches:, and not more than 10 percent
of the material should -pass the No. 60 sieve. The gradation of the niate'
rial is"not important as it does not serve as a filter. The thickness of
the envelope should be at least 3 inches.

Filters for drains are used to facilitate passage of water to the
drain and to prevent movement of fine particles of silt and sand into the
drain. Blinding material such.as topsoil, straw, salt hay, sawdust and
wood chips, or loose.c overings of tar paper over the'joint have provided
effective filtering action in some soils for long periods of time. Fiber
glass filter wrappings also are effective. However, the most suitable
material is the sand-gravel.filter. In addition to its filtering action,
sand -gravel filter material provides excellent bed material for cushioning
tile and. pipe when laid in the stony soils frequently encountered. A good
filter st * iould be well graded from coarse to fine and within a limited size
range of particles. Good concrete sand, as specified by the American
Association of Stat.e Highway Officials, has been found to meet tile require-
ments of an adequate filter for most soil conditions encountered. This
material is essentially a mixture of medium and.coarse sand with.fine and
medium -gravel, in which the particles are well graded from a minimum size
of about 1/2 millimeter (grains held on a No. 30 sieve) to a maximum of.
about 3/8 inch. Clean bank -run gravel, suitable for.use in mixing concrete,
usually is.available locally but should be checked for adequacy...Since
*filt6r material is rather fine,'clay or concrete draintile must be butted
against each other. For design of a filter see National Engineering Hand7
book, Section 16, or the local Technical*Guide.
Filter material, other than the manufactured types, should c,ompletely
encase the pipe with a thickness of at least13 inches. The trench in which
the drain is to.be,placed should be excavated below grade a depth equal to
the.thickness of filter and the trench then filled to grade.with the filter
material before ' laying the pipe. After the -pipe is laid, the trench should
be filled with filter material to the required depth. Filter and envelope
depths may range from a 3-inch cover over the,drain to within.1 foot of the
ground surface when interception through heavy soil is desired and found
practical.
Determination of Need of Envelopes or Filters
Thepurpose of these have been mentioned above as being related to
the soil types. Table 14-7 is a guide to relate the needs to the Unified
Soil Classification System, It will be noted that envelopes are optional
in all cases where filters are not used. The need for envelopes should be
based primarily on' soil permeability and requirements for bedding.

SUBJECT: MR. CROY'S DR-AINAGE COMPLAINT
At 9:00 a.m. Thursday, May 26, 1977, the following met at Nr.
Croy's to discuss drainage problem:
Mr. Croy - property.owner
2. Tom Belt.- Adjacent developer
3-. Allan Morgan - Reid'.s, Belt Eng.
4. Dick Allen - As.sistant City Engineer
S.. George Johnson - City Public Works Inspector
Th.e results of.this-,meeting.are.as follows:
1. Mr. -Croy will expose hi-s house footing drain -at
.the S..W. corner.to check for.plugged drains.
2. If this doesn't s ' olve problem, Mr. Belt will dig
ditch along E. side of Mr. Croy's house and �Jr.
Croy will furnish materials to install drain that
will daylight in his front yard.
Mr. Belt indicatedhe would work directly ivith Mr. Croy in
helping to'solve his problem thus eliminating the City's involvement.
