  • Front

CROWN OF THE ROAD

Represents the change in grade from the edge of the road to the center of the road.


parabolic, tangential, reverse

FINISH GRADE PLAN

existing and proposed: contours, utilities, buildings, structures, stormwater drainage inlets and spot elevations.

BRICK VENEER

shall be attached to the wall using wall ties.

PERMEABILITY OF THE SOIL

is the ability of the soil to allow water to pass through it. Low permeability= Clay High Permeability= gravel, sand.




influence permeability: type of soil and compaction.


not influence permeability: rainfall or shear strength

FACTORS THAT IMPACT A GRADING PLAN

1- architect design.


2- local municipality.


3- ADA.


4- utility systems.



TYPES OF FOUNDATIONS

slabs: flat land, continuous walls: can accommodate steeper slopes and piers: less invasive.

MAYOR LOAD CARRIERS IN DECKS

beams



PROPER GRADING DESIGN KEY TASK

positive drainage, all within the PL, no runoff going to the adjacent property, no grade changes within trees drip lines, do not take into account the previous use of the site.

POROUS PAVING SYSTEM

porous asphalt: better for colder climates.




porous concrete: better for arid climates.




precast pavers: not for heavy traffic, better for parking lots and driveways.

GREYWATER SOURCES

Good sources: showers, sinks and washing machines.




Bad sources: kitchen sink and dishwashers.

MIN ELEVATION POINTS IN A PLAN

all proposed bldgs on a grading plan should have spots elevations at every corner and an elevation per floor (typ 5 spots elev)

CONSTRUCTION JOINTS

placed at any time there is a stoppage in the pouring of concrete during construction. (use Dowel bar)

CONTRACTION JOINT

used to prevent cracking of the concrete.

ISOLATION/ EXPANSION JOINT

used between two pours of concrete but involves a material that is placed between the two pours the entire depth of the slab.

SOIL BEARING CAPACITY

1- organic soils have low bearing capacity.


2- it is acceptable to remove the poor soil and replace it with soil that has a greater bearing capacity.


3- driving piles and spread footing is also acceptable.

MORTAR

a mix of water, cement, and sand. It has high compressive strength and its used to bond masonry units together.

SLUMP TEST

performed during the pouring of concrete to determine the workability of concrete.



PERLOCATION TEST

to determine the absorption rate of the soil



PROCTOR TEST

to determine the bearing capacity of the soil.



ACCESSIBLE RAMP

min w 36"


min w 48" if making 180-degree turn


min 60x60 if the ramp is changing direction.

WORK ON SITE SEQUENCE

protect vegetation, remove topsoil, erosion control, clearing, demo

ACCESSIBLE WALKWAYS MATERIALS

good: concrete and wood.


for wildlife trail: crushed rock, pea sized gravel, bound wood chips, coarse gravel.

PHYTOREMEDIATION

PROS: aesthetically pleasing, less secondary waste, soil is usable after the treatment, less cost than mechanical treatment. Acceptable method for removing pesticides on soil.




CONS: slow process than mechanical treatment, possible groundwater contamination, can't remove contaminants on deep soil.



STORMWATER MANAGEMENT INFORMATION COMING FROM

local ecologist, climate, site and local municipality.

GRADING PLAN- WHEN POORLY DESIGNED

higher cost


increase flood potential


increase sedimentation


higher volume of runoff


lower quality of storm water

RAMPS

ONE WAY- 3' MIN


TWO WAY - 5' MIN


5' MIN FOR ALL RAMPS


30' MAX FOR LANDING DISTANCE


MAX SLOPE 1:12 OR 8.33%

INFILTRATION TRENCHES

use when there is only a small amount of land or space shall be used for more than one thing.

RETENTION BASINS

store water for a period of time until either infiltrates the soil or evaporates



DETENTION BASINS

permanent flood with water

BENCHMARK

REFERENCE ELEVATION IN A GIVEN LOCATION WHEN SURVEYING

CONTROL POINT

ACCURATELY SURVEYED COORDINATE LOCATION

DATUM

SYSTEM OF COORDINATE POSITIONS ON A SURFACE

DECKS- POST AND BEAMS

ALL BEAMS SHALL BE AT LEAST THE SAME WITH OF THE POST OR WIDER TO PREVENT WATER FROM GATHERING AT THE TOP OF THE POST



BEST MANAGEMENT PRACTICE- LIFE SPECTANCY

CONSTRUCTED WETLAND- 20 Y


WET POND - 20 Y


GRASSED SWALE AND SAND FILTERS - 20Y


INFILTRATION TRENCH - IS LIKELY TO FAIL FIRST BY GEOTEXTILE CLOGGING

WOOD DECKING CONSTRUCTION

flashing shall be used when moisture builds up may be a problem. hot dipped galvanized fasteners decrease corrosion. The blunt tips of nails do not increase the possibility of corrosion. Bottom of post shall be at least 6" above grade.

SOIL AND EROSION

SILT SOILS ARE MUCH EASIER TO ERODE THAN OTHER SOILS


ORGANIC SOILS ARE VERY PERMEABLE AND THEREFORE DONT ERODE AS MUCH AS SILT SOILS



AEOLIAN SOILS

SOILS ARE THOSE WHICH ARE TRANSPORTED BY WIND.

ALLUVIAL SOILS

TRANSPORTED BY STREAMS AND FORM DELTAS.

COLLUVIAL SOILS

MIXTURE OF ROCK PARTICLES AND SOIL PARTICLES THAT USUALLY ARE FOUND AT THE BASE OF SLOPES

VERTISOIL

IS A SOIL WITH A HIGH CONTENT OF EXPANSIVE CLAY

WOOD NOMINAL SIZES

1/4" SMALLER

TREE REPRESENTATION AT PLANTING PLANS

SIZE IS 2/3 OF THE MATURE TREE

EROSION CONTROL MEASURES

FOR RUNOFF: SEDIMENT BARRIERS & COARSE AGGREGATE


FOR WIND: TEMPORARY SEEDING, EROSION CONTROL BLANKETS, AND MULCHING
