Site Inventory and Analysis

Question 1

What is the difference between site inventory and site analysis

Answer 1

invetory is collecting data, analysis is interping the data

Question 13

What is the PLSS and what are its subcomponents

Answer 13

Public Land Survey System

method for dividing land into a nested grid system.

Within one quadrangle map there are:
16 townships (6 mile x 6 miles) 1 quadrangle contains 16 township grides

Townships are each labelled by their proximity to each quadrangle’s base line and principle meridian (or range lines)

Each township is subdivided into 36 sections. Sections are 1 mile by 1 mile or 640 acres - section is main unit of PLSS system

property boudary
public rights of way
easments
topo
exisitn gbuildings
exisitn utilities
flood zone classifications
adjacen property use and owners

Question 16

What is an As-Built survey and when are the conducted and what do the document

Answer 16

is to dcoument final built work and ensure a project was constructed according to documents. Generally conducted over course of construction to fully document how site elements differ from the design plans

they fully document all site elemtns as they exisit in the real world

Question 17

What is a boundary survey and when are they typically conducted and what do they document

Answer 17

Used to define the boudnaries of a parcel of land.

Typcially conducted before subdividning or imprving or building on land

incorporated into the SOW for ALTA survey

they document property boundaries Uses BEARING system to establish specific sruvey located points

Question 18

What is a topographic survey, when are they conducted, and what info do they document / provide to the designer

Answer 18

conducted as part of ALTA survey

commissioned to provide updated or higher resolution topographic info

typically include:
topographic contours
spot elevations
vegeation and physical attributes
utilties

Question 19

Survey Terms - What is aerial photography -

Answer 19

used for documenting static, hgih contrast, large scale phenomena, may also be used as raster image in GIS or CAD for other data

Question 20

Survey Terms - What is backsight

Answer 20

a point used to determine the elevation and/or angular orientation of a surveying instrument

Question 21

Survey terms - what is a bearing and how do you calculate one

Answer 21

notation for a line traveling between points, uses cardinal direction and degree angles - see diagrams

Question 22

Survey terms - Chaining

Answer 22

or chain survey - type of basic surveying in which only linear measurments are made and is sutiable for the survey of small flat areas

Question 23
