• State Regulations

• Executive Orders

• NAVFAC LEED


Navy LID Policy (Nov 2007)

• Set a goal of no net increase in SW volume and sediment/nutrient loading from major renovation projects (>$5 M) & construction projects (>$750 K) by FY 2011

• Directs that LID be considered for all projects that require storm water management

• Authorizes the establishment of a waiver process

• Requires that all efforts be made to incorporate LID in FY 08, 09, and 2010 projects


LID Policy Annual Report

Information required to be included:• Project title, brief description• Type of funds • Stage of the project (construction/design)• Was LID used?

– If so, what LID features were used and approximate the cost for installation LID features

– If not, provide a reason

Due by Nov 15th for the preceding fiscal year


MIDLANT LID Policy

• Implement NOW

• Include on all projects

• Only waiver is by MIDLANT CO


Energy Independence and Security Act of 2007 (EISA)

Section 438 “Storm Water Runoff Requirements for Federal Development Projects”

“The sponsor of any development or redevelopment project involving a Federal facility with a footprint that exceeds 5,000 square feet shall use site planning, design, construction, and maintenance strategies for the property to maintain or restore, to the maximum extent technically feasible, the predevelopment hydrology of the property with regard to the temperature, rate, volume, and duration of flow.”

• Each agency is responsible for ensuring compliance


Energy Independence and Security Act of 2007 (EISA)

• Each agency is responsible for ensuring compliance

• Reporting methods are TBD

• Footprint includes– All hard surfaces

• Buildings, pavement, sidewalks, porches, etc.

– Other compacted infrastructure areas that are effectively impervious


• Use all known, available, and reasonable methods of stormwater retention and/or reuse to prevent the off site discharge of stormwater runoff. There muste be a documented attempt to comply prior to requesting an exception due to technical infeasibility

• Site constraint examples:– Inadequate available land– Shallow bedrock, contaminated soils, shallow groundwater– Lack of non-potable reuse options– Structural or plumbing constraints– Soils that can not be sufficiently amended to provide

requisite infiltration rates

Maximum Extent Technically Feasible


EISA – Performance Options

• Option 1: Control 95th Percentile Rainfall Event (Q = P x Imp A)• Incorporate the 95th percentile storm in the SCS CN

method calculations (NAVFAC) • Manage rainfall onsite; infiltration, evapo-

transpiration, and harvest and reuse • Option 2: Preserve predevelopment hydrology

(rate, volume, duration & temperature)• Conduct hydrologic and hydraulic analyses • Quantify post-construction hydrographs for the 1, 2,

10, 25, 50 and 100 year 24 hour storm events • Maintain pre-development hydrographs for these

storm events


UFC 3-210-10August 2009

• Revised AUG 2009 to accommodate Navy LID Policy and EISA 438

• Defines pre-development condition – Conditions immediately prior to human development

• Defines LID design storm event– Larger of 95th percentile rainfall (24 hr) or State/local

requirement

• Runoff and volume calculations– Use NRCS TR-55


UFC 3-210-10 LIDAugust 2009 Draft

• Provides guidance on use of integrated management practices (IMPs)

• References other UFC relevant to design

• Navy Guidance Document– Separate document providing assistance on

interpretation and implementation of LID – Discusses planning, design, and maintenance

EISA ImplementationDraft DOD Direction

• 5000 SF footprint– Only includes building and pavement– Does not include internal renovation or maintenance– Does not include resurface of existing pavement

• Maintain pre-development hydrology – Pre-development hydrology is defined as pre-project conditions

wrt temperature, rate, volume, and duration

• Maximum Extent Technically Feasible subject to:– Site constraints– Regulatory constraints– Structural limitations– Demand for recycled water


EISA ImplementationDraft DOD Direction

• If Design to METF but can’t Maintain Predevelopment Hydrology– May apply LID on nearby DOD property (available

resources)

• Redevelopment Projects– Where no increase in post-project stormwater runoff (vice pre-

project) is proposed, DOD components should consider restoration of natural hydrological conditions to the maximum extent practical

• NPDES Stormwater Permits– EISA 438 requirements independent of CWA– Permits should not include EISA requirements unless first

promulgating EISA like requirements into CWA authority


EISA Draft Implementation Direction for DoD Projects

• Evaluate design options to meet objective to the maximum extent technically feasible (METF)

• Document EISA design and construction costs• Complete a post construction analysis of

features


EISA DoD Implementation Process

4. Finalize design and estimate cost

1. Determine applicability Requirement: apply to all Federal projects with a footprint greater than 5,000 square feet

1. Determine applicability Requirement: apply to all Federal projects with a footprint greater than 5,000 square feet

2. Establish design objective Requirement: maintain or restore predevelopment hydrology

OPTIONS (use only 1)

1Total volume of rainfall from 95th percentile storm is to be

managed on-site.

Design water volume(to be retained)

2Determine predevelopment hydrology based on site-specific conditions and

local meteorology by using continuous simulation modeling techniques, published data, studies, or other

established tools. Determine water volume to be managed onsite.

remaining water volume?

Selected on-site design options

Selected off-site design options

Use any combination of on-site options to achieve the design objective to the METF.

Document site-specific constraints.


• Retaining storm water on site would adversely impact receiving water flows

• Site has shallow bedrock, contaminated soils, high groundwater, underground facilities or utilities

• Soil infiltration capacity is limited

• Site is too small to infiltrate significant volume

• Non-potable water demand (for irrigation, toilets, wash-water, etc.) is too small to warrant water harvesting and reuse systems

• Structural, plumbing, or other modifications to existing buildings to manage storm water are infeasible

• State or local requirements restrict water harvesting

• State or local requirements restrict the use of green infrastructure/LID

State Design Requirements

• Varies State to State– Water quality volume– Water quality pollutant (VA)– Design storm– Predevelopment condition – Runoff reductions for redevelopment

• State regulations changing– VA out for public comment. More strict– DE under review– NY review process in 2010


• Minimum Measure 5 – Post Construction Stormwater Management– Provide BMP location and acres treated– Conduct inspections to insure proper operation– Require long-term operation and maintenance

• TMDL Wasteload Allocations– Identify if BMP discharges to impaired water– Post construction stormwater management must be

consistent with TMDL

MS4 Permit Requirements


• Must determine most restrictive design requirement LID policy, UFC, EISA, NPDES

• Requirements could change in future• Documenting proper operation and maintenance

of IMPs is important

Leadership in Energy and Environmental Design (LEED™)

• Definition:– LEED™ is a voluntary, consensus-based national standard for

developing high-performance, sustainable buildings

• LEED™ Green Building Rating System created to:– Define “green building” by establishing a common standard of

measurement– Promote integrated, whole-building design practices– Recognize environmental leadership in the building industry– Stimulate green competition– Raise consumer awareness of green building benefits– Transform the building market


• Purpose: Reduce cost of shore facility ownership by implementing sustainable development concepts and principles

• Requirements:– Use leadership in energy & environmental design

(LEED) • Projects not covered by LEED use LEED checklist

• Impact to installations if not implemented:– Possible loss of Navy project funding– Possible loss of Navy mission & BRAC consideration
