Site Inventory and Analysis Flashcards
What is the difference between site inventory and site analysis
invetory is collecting data, analysis is interping the data
What is the role of site inventory in the project design process
to identify a community’s natural and cultural resources to inform the project decision making process
REMEMBER, site inventory is informed by site program and site seleciton process and is not linear
A site’s proposed _____ plays a key role in determining what data is relevant and should be collected during th esite inventory process
The project program - site inventory originates from site program and selection
Site inventory typically begins with…
a site visit / site reconaissance. May also involve reviewing very basic data of the site
While a wide range of data can be collected, what 4 limitations typically drive designers to focused or limited site inventory and analysis
sbrp
project schedules
budget,
development regulations ( permitting requirements
proposed project program
What does a LA develop after initial reconnaissance.
base map
What is a basemap used for
to catalog site attributes,
a template for site analysis,
template for any subsequent land use planning and design to occur on site
What specific type of inventory maps wetlands, archeolgical sites, scenic views, sig wildlife habitats, ecological and cultural resources such as forests floodplains farmlands aquifers and historic structures
Community resources survey
a basemap will tyypcially be generated from _______ and will generally contain what data…
- ALTA - american land and title association
- property boudnary
public rights of way
easments
topo
exisint buildings
exisitng utilities
flood zone calssificaitons
ajdacent property uses and owners
Aka whats there . Who owns it. Flow / contour
A basemap may inlcude basic GRAPHIC info such as
site location / context map
title informtion (project name locaiton designer etc)
norht arrow
graphic scale
data sources
For large scale sites (500 acres for example) or multiple sites across similar are - what publicly available data sources are recommend to develop a base map
USGS topographic maps (aka USGS quadraangle or 7.5 minute quadrangle maps) =- typ available at 1:24,000 scale.
What info do USGS quadrangle maps contain
topo at 40’ contours intervals
township range and section info
transportation infrastrucutre
rivers floodplians wetlands and basic physiographic data
buildings and new construction since last printing
** maps from 1884 to 2006 (when physical printing stopped) are part othe HTMC historical topo map collection
What is the PLSS and what are its subcomponents
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
What 4 land / base map survey types are used in Inventory and Analysis
ALTA Sruvey
As-Built Survey
Boundary Survey
Topographic Survey
What is an ALTA survey and what do they documnt
Title survey or Amerian Land and Title assocation survye - used to recode a property for a real estate transation.
They document typcially:
property boudary
public rights of way
easments
topo
exisitn gbuildings
exisitn utilities
flood zone classifications
adjacen property use and owners
What is an As-Built survey and when are the conducted and what do the document
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
What is a boundary survey and when are they typically conducted and what do they document
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
What is a topographic survey, when are they conducted, and what info do they document / provide to the designer
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
Survey Terms - What is aerial photography -
used for documenting static, hgih contrast, large scale phenomena, may also be used as raster image in GIS or CAD for other data
Survey Terms - What is backsight
a point used to determine the elevation and/or angular orientation of a surveying instrument
Survey terms - what is a bearing and how do you calculate one
notation for a line traveling between points, uses cardinal direction and degree angles - see diagrams
Survey terms - Chaining
or chain survey - type of basic surveying in which only linear measurments are made and is sutiable for the survey of small flat areas
survey terms - infrared aerial
typical used to track the growth of veg over time. infrared can track tree diseas, inseti damage etc
survey terms - leveling
process of determining the height of one level relative to another. used in surveying to establish the elevation of a point relative to a datum
survey terms LIDAR
Light Detection and ranging - imaging tech used for aerial site surveys. lidar can “see” through veg and detec topo to produce complete and accurate topo - more than aerial photo
survey terms - Stadia measurement
survey technique used to observe height of a graduated, upright rod to infer horizontal distance
survey term - traversing
survy technique that maps an area of land using a series of interconnected lines
What is Site analysis? what does it Identify and what information does it provide and how is this related to site inventory?
Site analysis synthesizes date collected during the site inventory
It identifies opportunties and constraints for a specific project or land use
information collected during site inventory and drafted in inventory maps is analyzed and interpreted in site analysis to determine feasability and suitability for the proposed project
How can site analysis inform or impact site program?
alter or change program given opps and constraints
What is another name for site analysis?
Suitability analysis - althoght this is techncially its own thang
What are the three basic steps of a land use suitability analysis. d, m, i
Define criteria - Id suitability critera for a given land use
collect and map relevant data
ID map site locations with attribute values that meet suitability criteria
The basic goals and objectives of a project are refined and shaped by _____what (outlined in site analysis)
Opportunties and constraints
Program can determine what inventory and analysis points are focused on during this process.
what opportunties and constraints might be focused on at a site for large distribution center
constraints - steep slopes, lack of access to nearby rail / trucking infrastrcuture, local oppostion
opportunties: zone code that approves the use, soils with adequat ebearing capacity
browfield with compaitble infrastructure in place
How does ID’ing opps and constraints help the client
clarifies if and how developmetn should proceed
may introduce other compatible or alternative uses
List example categories of data that is typically encountered during site inventory and some of their related sub-data sets
