STREET INTERSECTIONS:
Generally at one street(call Demonant.Street) shall maintain grade and crown
through the intersection. r'
GRADE CHANGES:
Minor grade changes shall be avoided if at all possible - angle points, if minor
grade change cannot be avoided, will only be allowed where there is no change
in direction of grade when the total grade change is less than a tenth of a percent
- where there is a change in direction of grade on a crest situation greater than
a tenth of a percent a vertical curve shall be used. - In the case of a change
in direction of grade which results in a low point sage an angle point shall
be employed in such cases where a long flat spot would result .it° a vertical curve
were employed but in no case where the total grade changeis than one
percent.
At intersections where the total of both street grades is more than six percent
or one street has a grade of more than four percent profiles for the edge of
asphalt plotted along edge of asphalt.elevation shall be shown as well as center-
line elevations.

INTERSECTIONS:
In cases where the nondominant street at an intersection has a grade
greater than cross slope of the dominant street shall be projected to a point.
50 feet from the centerline of the dominant street to determine the elevation
for a vertical curve connecting the nondominant street to the dominant street
and that vertical curve shall length of 50 feet - this is to insure a
reasonably leval area at the intersection for stopping together with providing
proper sight distance.
WATER:
Minimum line size - 6" (except in the case of short cul-de-sacs not involving
fire hydrants where two inch lines will be allowed).
PIPE MATERIALS - AWWA class 150 ductile iron cement lined - AWWA Class 150 PVC. -
only allowed in areas with native sandy soil.
VALVES - 10" and smaller lines, gate type - 1.2" and larger lines - Butterfly type
WATER LINE LOCATION IN RIGHT-OF-WAY - 15 feet north or west of centerline right-
of-way - exception allowed where connecting.to existing lines incompatible with
such:
VALVING -.On single lines valve.spacing shall be no more than one block or
1,320 feet whichever is lesser - intersection of water lines, valve all but
one leg - valves to be located on the projection of property lines through
intersections..
WATER LINE DESIGN CRITERIA
For R-1 Surburban zoned areas without irrigation water.
- Maximum volicity of flow five feet per second without fire flow
Maximum volicity of flow eight feet per second with fire flow
- System shall be designed to provide at least 90 feet of water head (approximately

System shall be designed to yield seventy feet of waterhead (approximately
30 PSI) with a consumption of six gallons per minute per ,connection without
fire flow
- System shall be designed to yield fifty feet of waterhead (approximately
20 PSI) with a consumption of six gallons per minute per connection and
a fire flow of 1,000 gallon per minute at at hydrant location.,'.
NOTE: If other than detached single family residences are to be allowed in

BOOSTER STATION DESIGN STANDARDS/CRITERIA
-

J . A:1 A•� � ,

This requirement is special and only applies to the Riverview Heights area
(section 14 T N9, R29 EWM) since this area is to be served by an in line
°i booster station which must respond to high peak hour demands. on a direct
basis the criteria is substantially higher than would normally be associated
with a system where the source had storage connected with it.
BOOSTER STATION DESIGN CAPABILITY:
Fire flow reserve of 1500 gallons per minute or that of the largerst pump
within the booster station whichever is greater - together with six'gpm
per connection or potential dwelling unit for the first five hundred connections
- plus five gallons per minute for the next 250 - plus four gallons per minute
for the next 250.
Since the particulars of the design of an in linebooster station of this size
involve rather specialized engineering skills and since the proper operation
of the booster station is of paramount importance to public health and safety
and since the City of Pasco will ultimately own and operate the booster station
the City of Pasco deems that it is in the City's best interest to have a
consultant acting as an agent of the city review and make recommendations to
the city as to the capability and desirab`iliy of the booster station..as designed
by the developer and his agents, to meet the design criteria and also to such
in an economic and functional sense when measured over a period of several years.
