STATUS REPORT ON COUNTY WATER & SEWER PLAN
GREATER WILMINGTON AREA 201 FACILITIES PLAN
Presentation to Board of County Commissioners
16 December 1974
1 We are pleased to have this opportunity to present this status report
on the progress of the County water and sewer plan and corresponding
Greater 6Vilmington Area 201 Facilities Plan It must be remembered that
these undertakings are closely interrelated, but are two completely
separate undertakings
a 201 Facilities Plan Being prepared to satisfy requirements of
1972 amendements to Federal Water Pollution Control Act Briefly, it will
(I) Analyze multiple alternatives for wastewater treatment
facilities to meet the present and projected needs of the study area
(2) Determine the most cost effective, environmentally sound
and socially acceptable solution to the problem
(3) Recommend a selected plan for meeting the regional wastewater
treatment needs within the study area
(4) Recommend institutional arrangements for implementation of
the plan
b County-Wide water and sewer preliminary engineering report will
(I) Address regional water and sewer needs throughout the entire
county (201 plan not concerned with water)
(2) Delineate water distribution and sewage collection systems
throughout county - broken down into logical service districts or subareas,
and further identify areas of most critical need based on existing develop-
ment patterns
(3) Present detailed cost estimates for project implementation
on an area basis
III

(4) Analyze and recommend plans for financing project undertaking.
PER will provide sufficient detail and basis for immediately proceeding
~~2~-s~~-S~'
with,, projects in accordance with the desires of the Board and the local
people
Now where do we stand in our current effort?
2. The Wrightsville Beach 201 Facilities Plan (Part I of GWA plan)
was completed and submitted for review in July
a Explain reasons for accelerating this portion of plan
b. After over 2 months of review by DEM local area office, we. received
review comments (comment)
c It took another month to arrange Raleigh DEM/WB meeting
d Revisions are underway and we plan to resubmit by end of month
3 Progress on balance of GWA plan
a Delays experienced as a result of lags in delivery of
(I) New tax maps (relate discussions with Richard Epling)
(2) Population projections/development/planning data from
City/County Planning Department (relate discussions with Dick Fender,
Bill Farriss)
b Despite this, we have
(I) Completed much of our office and field data collection
including
(a) Environmental data base, climatological, geological,
hydrological, etc
(b) Survey of existing wastewater facility, municipal and
private
(c) Data from City on water consumption and sewage flows,
systems maps, etc
.r
3
(d) Working with State DEM on water quality goals (receiving
waters)
(e) Initial formulation of regional conceptual alternatives
c Begun Inviltration/Inflow analysis
(I) Data collection from city
(2) Initial systems survey complete
(3) Plan to start detailed I/I survey just after first of year,
hope to complete by end of January
d Field surveys (parties in field) to establish ground truth to
determine actual locations of outfalls, pumping stations, etc (Waited
for map as long as we could - finally decided to initiate field surveys
without them)
4 All of these efforts will complement preparation of PER which will be
put together simultaneously with 201 facility plan /
a For example Population and development data being provided
by planning department, plus results of our field surveys, will provide
us with a computation base to size and locate actual water and sewer lines,
predict future waste loads and flows, determine treatment facility require-
merits, etc
5. Summary: We feel we have made good progress to date We should be
able to move ahead now that we have planning data base and hopefully the
maps, in the near future

POPULATION AND LAND USE INFORMATION FOR
WATER AND SEWER SYSTEM DESIGN
I Background
y
Henry von Oesen and Associates, Consulting Engineers, are currently under
contract to the New Hanover County Board of Commissioners to prepare two
studies
~~~- ~_.
1 A County-wide water and sewer plan which is intended to ultimately
provide water and sewer service to all areas of the County
2 A "201 Facilities Plan" for waste water treatment in the Greater
Wilmington 201 Area and the Carolina-Kure Beach 201 Area The 201
Facilities Planning Program is an outgrowth of the Federal Water
pollution Control Act of 1972, and it is intended to insure that
Federally funded treatment facilities are effective in achieving
the long-range objectives of the Act -- clean water
Both of these studies bear a crucial relationship to the County's land
use planning program First, a current Land Use Plan is required for the proper
engineering of the water and sewer systems -- sizing, placement of Iines, treat-
ment capacity, and so forth Second, policies concerning water and sewer systems
are among the most effective tools for guiding community development available
to local government Historically, it has been shown that the placement of water
and sewer facilities shapes the pattern and character of urban growth
In an optimal situation, the County's water and sewer plan would be prepared
subsequent to the analysis of the Planning Area's population and economy, and the
formulation of a Land Use Plan. In the case of New Hanover County, however,
contracts for the planning of water and sewer facilities were let far in advance
of the completion of the Land Use Plan, making this sequence impossible
The Planning Department has agreed, therefore, to furnish the Engineers
with this report containing preliminary population and land use information for
the expressed purpose of designing a County-wide water and sewer system However,
within the context of this land use information, the proper phasing of water
and sewer facilities must be stressed Planning for the development of water
and sewer facilities to serve the entire County within the next 20 years would
create prime developable land far in excess of the amount required to accommodate
projected population growth This situation would undoubtedly create serious urban
sprawl conditions, meaning potential problems for the County's transportation
system, its schools, and other community facilities
It is emphasized that the information in this report is based primarily on
existing data and the preliminary findings of current studies, and as such it
should not be construed as the final land use policy recommendations of the
Department
II. Organization
This report, including maps and descriptive text, addresses six basic
2
elements relating to future land uses in the New Hanover County
A. Population projections for the 1975-2000 period,
B. Based primarily on existing population distributions but also
considering physical conditions, zoning, and other factors,
an estimate of the distribution of the County's projected population,
C. Future land use location criteria,
D Estimated land needs for the planning period,
E Generalized future land use patterns with estimated resi-
dential densities
F An estimate of the amount of suitable, developable land in each
planning area
After consultation with the County's Engineers, it is felt that, consistent
with existing time and data constraints, this information will provide a suf-
ficiently reliable land use base for the preliminary design of a County-wide
water and sewer system
III Delineation of Planning Areas
For the purpose of detailed planning analysis, it is customary to
delineate several smaller sub-areas within the primary area of planning juris-
diction The Planning Areas defined in this study are used for two purposes
1) To estimate the geographic distribution of the County's projected
population, and
2) To calculate the amount and location of suitable, developable land
available in the County
Since final decisions on the delineation of Planning Areas for the
Comprehensive Planning Program have not been made, the areas shown in this
report are provisional, they are, however, useful for statistical analysis in
that they conform to boundaries for which published data are available
IV Population Projections
The Planning Department has recently completed a preliminary draft of a
Population Study in which the County's population is projected in 10-year in-
crements to the year 2000 A "Cohort-Survival" technique, regarded as one of
the most reliable in dynamic growth environments, has been used in making the
projections This technique treats all three population growth variables in
making the projection -- births, deaths, and population migration
The projections shown in the following Table have been developed in the
Population Study and are used in calculating the County's land needs and in
a
3
estimating the geographic distribution of population in the year 2000.
Year Pro,jected,Population
1980 101,300
1990 124,600
2000 151,100
V. Population Distribution
The detailed studies which are required to forecast, within an acceptable
accuracy range, the geographic distribution of future population are not complete.
However, the projected population distribution shown on Map 1 does provide some
insight to the future, if current development trends continue Consequently
the year 2000 distribution has been estimated by applying the 1970 percent
distribution of population among planning areas No weight has been given to
the capability of land within the planning area or to the 1970-74 development
trends These variables will be the subject of subsequent studies
VI Land Use Location Principles
.Location principles may be defined as guidelines for the placement of
uses on the land They involve a broad range of physical, social, and economic
considerations, and they generally involve intensive staff analysis prior to
their adoption as County policy The design and adoption of land use location
criteria are crucial steps in the land use planning process
Studies of use location requirements have not yet been undertaken by the
Planning Department In lieu of these studies, generally accepted planning
standards have been used as principles for locating uses on the land. However,
it should be stressed that these principles are very general and that they may
be altered as the County's planning program progresses.
A. Industrial land uses
1. Extensive -- generally characterized as heavy industry with
high land requirements
a) Good access to all major modes of transportation
b) Suitable site characteristics
(1) Good Soils
(2) Large undeveloped tracts
c) Semi-dispersed sites to minimize environmental problems
consistent with the need to provide public services as
efficiently as possible
d) Compatibility with existing land uses and activities -- using
natural open space buffers where possible.
4
e) Priority should be given to areas currently served by
public services
2. Intensive -- generally characterized as light industry with
lower land demands
a) Should occupy sites in close proximity to urbanized area.
b) Major transportation considerations should be highway, rail,
and air with major attention to access to local transportation
network.
_ c) Suitable site characteristics
(1) Minirouro of 25 acres
(2) Suitable soil conditions
d) Site should be compatible with surrounding uses and should
maintain open space buffer where feasible.
e) Industries should be clustered where possible.
B Residential land uses
1. Suitable site conditions -- soil capability
2 Close proximity to major thoroughfares and transit systems.
3. Easy access to employment and commercial areas
4. Close proximity to existing and planned community facilities.
a) Schools
b) Public safety
c) Water and s ewer
C Because of the very specialized and varying nature of commercial land
use location principles and the existing problems associated with commercial
uses in New Hanover County, no general location criteria are proposed, nor
are future commercial uses indicated on the future land use map These recom-
mendations have been reserved until more planning studies are complete Moat
commercial uses are, however, generally located in close proximity to areas of
moderate and high residential land uses, and the water and sewer facilities
planned for these uses should also accommodate commercial uses as well.
VII Estimated Land Needs
Estimates of New Hanover County's land needs for the next 25 years are
an attempt to set aside realistic amounts of land to accommodate its future
population The following estimates are based on projected population, economic
characteristics, and generally accepted planning guidelines. They are intended
as rough estimates, and they contain generous inflation factors to provide _
5
flexibility in locating and developing future industrial and residential
sites.
A. Industrial land needs
1. $asic assumptions
a) Employment
1) Workforce 40% of total population
2) Industrial workers 35% of total work force
3) Heavy industrial workers 70% of total industrial
workers
4) Light industrial workers 30% of total industrial
workers
b) Worker/density ratios
1) Heavy industry -- 3 workers/ac
2) Light industry -- 11 workers/ac

Total 68,151 6679 2226 2862 260
B. Residential Land Needs
For the purposes of this report, two basic steps are involved in the esti-
mation of the County's residential land needs for the planning period
1. By assuming an average household size of 2 5, the County's population
growth has been converted to household growth Between 1975 and 2000
it is estimated that the total number of families will increase by
27,200.
2. The second step involves estimation of the percentage of these families
which will be accommodated at high, moderate, and low residential
densities. Although the variety of factors influencing residential
densities makes these estimates difficult, family income statistics
and building permit trends can be used as crude indicators of the
future distribution of dwelling units among the three density ranges.
6
Using the generally accepted standard that families on the average can
afford to spend approximately one-fourth of their income on housing, the 1970
New Hanover County family income distribution can be converted to the following
estimates of the percentage of County families which can afford to purchase
housing in various value ranges
Value Range Percent of Families
Les s tt-an $12, 000 26
$12,000 - $24,100 36
$24,100 - $36,100 24
$36,100 - $54,200 11
Over $54,200 ~ 3
By assuming that the major factor creating demand for housing and pro-
duction coats (land and construction) and that generally speaking as selling
prices decrease residential densities must increase, it is possible to use the
preceding information to estimate the future need for land in various density
ranges
Housing Value Range
Less than $12,000
$12,000 - $24,100
$24.100 - $36.100
$36,100 - $54,200
More than $54,200
Density Category

Moderate
Low
Percent of Families

Building permit trends provide another perspective by showing the housing
densities which have been accepted by New Hanover County families in the past
According to the City and County Inspection Departments, between 196b and 1973
forty-three percent of all residential building permits issued in the County
were for multi-family structures However, in 1972 and 73, of the total permits
issued, multi-family permits accounted for 53% and 63%, respectively. This in-
crease in multi-family permits appears to indicate wider acceptance of higher
residential densities
By comparing housing value information and building permit trends, the
following density assumptions have been made to estimate future residential
land needs:
Classification
High
Moderate
Gross Density Range
6-13 du's/acre
3-6 du's/acre
Percent of Households
55
25
Law 1.5-3 du's/acre 20
7
Applying these density assumptions to the County's projected household
growth, the following Land needs have been estimated;
Classification ~kHouseholds Average Gross Density Total Raw Land Needed
High 14,960 9 du's/ac 1700 acres
Moderate 6,800 5 du's/ac 1400 acres
Low 5,440 2 du's/ac 3700 acres
Considering current and past development trends and the existing level of
community facilities developed within the City of Wilmington, it is felt that
the bulk of the County's high density residential development will be located
within the City. , ,
VIII. Future Land Uee Patterns ,
Map 2, illustrating generalized future land use patterns in the County,
represents a synthesis of the population estimates, land use location principles,
and land needs estimates which have been discussed, as well as the County's
existing land use plan (1968) and zoning map The map is not intended to program
development for the 1975-2000 time period, rather it is intended to represent
an optimal pattern of land uses as the County approaches full development at
some point in the future. The future land use patterns represent some inherent
compromises which result from the constraints of existing development and de-
velopment trends.
Although the map is generally self-explanatory, the following clarifications
are needed
1. Soil capabilities have been used as the physical basis for
identifying developable land, but it should be recognized,
that the soils are not the only physical factors having a
bearing on development In some cases, the limiting characteristics
of soils may be overcome by large investments in land preparation.
At the same time, as the Department's natural system analysis con-
tinues, additional development constraints may be identified and
additional areas may be placed in conservation categories.
2. Within the areas designated conservation, there are many sites
having high development potentials, however, they have a low
priority from the standpoint of water and sewer service
3 The industrial area planned along the Northeast Cape Fear River
is intended to be extractive in nature and should not be served
with water and sewer
IX Developable Land Analysis
To provide more detailed guidance within the generalized land use
patterns shown on Map 2, a summary of developable land is provided in Map 3
This map shows the. total amount of developable land (suitable from the stand-
point of soils and undeveloped) within each planning area and should provide
guidance in setting priorities for the development of water and sewer facilities.

Maps (1" = 2000') showing the actual location of this land are available in
the Planning Department
