NOTE: Steel Grates Are Required On Inlets With Traversable Slots And On Inlets where Bicycle Traffic Is Anticipated.

GENERAL NOTES

1. These inlets are suitable for bicycle traffic and are to be used in ditches, medians and other

areas subject to infrequent traffic loadings but are not to be placed in areas subject to any

heavy wheel loads. These inlets may be placed in areas subject to occasional pedestrian traffic

such as landscaped areas and pavement areas where pedestrians can walk around the inlet.

2. Inlets subject to minimal debris should be constructed without slots. Where debris is a

problem inlets should be constructed with slots. Slotted inlets located within roadway

clear zones and areas subject to bicycles and/or pedestrians shall have traversable slots.

The traversable slot modification is not adaptable to inlet Type H. Slots may be constructed

at either or both ends as shown on plans.

2’-1 7/8 " 2’-1 7/8 " 2’-1 3/16 "

1/8 " Clearance Over Rivets (Typ.)

3. Steel grates are to be used on all inlets where bicycle traffic is anticipated. Steel grates

are to be used on all inlets with traversable slots. Either cast iron or steel grates may be

used on inlets without slots where bicycle traffic is not anticipated. Either cast iron or

steel grates may be used on all inlets with non-traversable slots. Subject to the selection

described above, when Alternate G grate is specified in the plans, either the steel grate,

hot dip galvanized after fabrication, or the cast iron grate may be used, unless the

plans stipulate the particular type.

4. Recommended maximum pipe sizes shown are for concrete pipe. Size for other types of

pipe must be checked for fit.

5. All exposed edges and corners shall be 3/4 " chamfer or tooled to 1/4 " radius.

6. Concrete inlet pavement to be used on inlets without slots and inlets with nontraversable

slots only when called for in the plans; but required on all traversable slot inlets. Cost to

be included in contract unit price for inlets. Quantities shown are for information only.

7. Traversable slots constructed in existing inlets shall be paid for as inlets partial.

For conversion work and method of payment see ’TRAVERSABLE SLOT INLETS

(PARTIAL) FOR EXISTING INLETS’.

8. Sodding to be used on all inlets not located in paved areas and paid for under contract

unit price for Performance Turf, SY.

9. For supplementary details see Index No. 201.

10. All reinforcing is Grade 60 bars with 2" min. cover unless otherwise noted. Bars to be cut or

bent for 1 1/2 " clearance around pipe opening. Provide one additional #4 bar above and

at each side of pipe opening.

Top, Seats And Slot (s)

Either Removed Or Embeded)

1. The general purpose of these conversions is to remove the hazard

of the protruding inlet top, while not creating a hazard by depressing

the top too deeply.

2. The corrective procedure depends on the approach ditch grade and

hydraulic requirements of the site. The selection of the appropriate

case depends on the relationship between inlet top and ditch elevation,

and, on the vertical clearance between the top of the uppermost pipe(s)

and the grate. The purpose for the Case 1 conversion is to add the

traversable slot to an existing inlet where top removal, change in

grate elevation and ditch transitions are not required. Case 2 will

normally be applicable to ditches with flatter grades adjoining the inlet.

Case 3 will normally be applicable to ditches with steeper grades

adjoining the inlet where build up of the existing ditch is acceptable.

3. The designer shall stipulate in the plans which case is to be constructed

at each individual inlet location.

Where the existing inlet top is above the existing ditch (Case 2) but

borrow material will be required to adjust the ditch (Case 3), and

vertical clearance or other conditions do not prevent removal of the inlet

top, the designer should call for Case 2. The designer shall determine

if ditch reconstruction is required more than 35 feet beyond any

traversable slot side and shall include separate pay items in the plans

to cover the cost for that portion of required ditch reconstruction

exceeding the 35 foot limit. The designer shall also determine whether

ditch pavement is required for ditch restoration within the 35 foot limit and

include that pavement under a pay item separate from the inlets partial.

When the detention ditch concept is to be used with Case 3, the designer

shall stipulate ’ Case 3 (Detention) ’ in the plans.

The designer shall determine whether tight soil or other conditions at each

individual inlet indicates the need for underdrain in Case 3 conversions

and shall call for Underdrain, Type ~ in the plans.

1. Existing inlets converted to traversable slot tops under Cases 1, 2

and 3 shall be paid for as inlets partial, each. Case shall not be

included in the pay item description.

2. All ditch reconstruction work within 35 feet of each traversable slot

conversion, whether required by these details or as a direct result of

the conversion, shall be included as a part of the partial cost.

Reconstruction work shall include excavation and removal of surplus

materials or borrow materials in place, grading, compaction, shaping

and restoration of disturbed turf. Sodding, ditch pavement and underdrain are

not included as part of the inlet partial cost and are to be paid for

separately.

3. Concrete inlet pavement and sodding shall be in accordance with the

sections on this detail and with the Plan on Sheet 3 and Sections AA,

BB and CC (as Case 1) and tabular quantities on Sheet 4.

4. Unit price and payment shall constitute full compensation for inlet

conversion (including concrete inlet paving and replacement grate(s)),

ditch reconstruction, restoration of disturbed turf, and shall be paid for under

the contract price for Inlets (DT Bot) (Type ) (Partial), each.

Sodding shall be paid for under the contract unit price for Performance

Turf, SY.

Ditch pavement shall be paid for separate from the inlet by pavement

type(s) and unit(s) as called for in the plans.
