Common Questions
Is using wood for garden borders or decks a bad idea here given the wildfire risk we hear about?
In Nanawale Estates' Extreme Fire Wise (WUI Zone 2) rating, non-combustible materials are a primary defense strategy. Crushed basalt or lava rock borders are superior to wood for creating mandatory defensible space. They provide permanent, zero-ignition-risk hardscaping that will not degrade. For any decking, consider composite or metal systems, as traditional wood structures represent a significant fuel load within the required 30-foot defensible zone around your home.
How do we maintain a healthy St. Augustine lawn here without stressing our rainwater catchment system?
Successful irrigation here depends on optimizing your gravity-fed catchment. First, ensure your filtration system is clean to prevent emitter clogging. Second, schedule irrigation for early morning to minimize evaporative loss, which is significant given the rapid drainage. Third, base watering cycles on soil moisture sensors rather than a timer, applying deep, infrequent watering to encourage deeper root growth that can better access sub-surface moisture in the volcanic cinder.
We have a sudden HOA compliance notice for overgrowth. How quickly can a crew address this, and what's your dispatch route?
For urgent HOA compliance, we can typically dispatch an electric maintenance crew within the same business day. The route originates from our staging area near the Nanawale Community Longhouse, proceeding directly onto HI-132 (Pahoa-Kapoho Rd) for efficient access to the subdivision. This logistics plan targets a 45-60 minute arrival window, factoring in the travel time from central Hilo, to initiate immediate vegetation management and debris removal.
Our soil seems to drain instantly and our lawn looks thirsty. Is this normal for Nanawale Estates, and what can we do about it?
This is a defining characteristic of lots in Nanawale Estates. With an average house age of 1985, your 40-year-old soil profile consists of mature Andisols—volcanic cinder with high permeability. While excellent for drainage, this structure often lacks stable organic matter to retain moisture and nutrients. Core aeration followed by amending with composted organic material is critical to improve water-holding capacity and build a resilient soil biome, counteracting the inherent rapid drainage of the parent material.
We've spotted what looks like invasive Guinea Grass. How should we handle it without harming nearby natives or violating county codes?
Guinea Grass is a high-priority invasive that must be addressed before seeding. Manual removal, including digging out the root crown, is most effective and avoids herbicide drift. Any targeted chemical treatment must strictly adhere to the Hawaii County Fertilizer Management Code, which prohibits certain applications during forecasted rain events to prevent nutrient runoff into the rapid-drainage soils. For large infestations, consult a licensed applicator who can create a management plan compliant with local runoff restrictions.
We're adding a patio but are worried about creating runoff issues. What are the best practices for our property?
Given the high permeability of your volcanic cinder soil, the primary goal is to maintain its natural infiltration capacity. Using crushed basalt or lava rock as a base and setting pavers with permeable jointing sand creates a system that meets Hawaii County Planning Department runoff standards. This approach allows stormwater to percolate directly into the subsoil, mimicking the site's natural hydrology and preventing any alteration of surface water flow that could require engineered drainage solutions.
We want to regrade a soggy corner of our 0.25-acre lot. What permits and contractor qualifications are needed?
Any significant regrading on a 0.25-acre lot typically requires a Grading and Grubbing permit from the Hawaii County Planning Department to ensure erosion and sediment control. The contractor must hold a C-27 Landscaping license or a C-12 Earthwork and Paving license from the Hawaii Contractors License Board. This licensing is non-negotiable; it guarantees the professional has the bonding and expertise to manage soil movement, protect utilities, and prevent off-site sedimentation, which is a critical concern in this community.
We want to reduce mowing and gas equipment noise. What are effective native alternatives to a traditional grass lawn?
Transitioning to a native groundcover palette significantly reduces maintenance and aligns with evolving noise ordinances. A matrix of drought-adapted natives like Pa'u o Hi'iaka (Jacquemontia sandwicensis) with accent plantings of 'Ohi'a Lehua and Hapu'u Fern creates a layered, fire-resistant landscape. This biodiverse approach eliminates weekly mowing and gas-powered blowers, leveraging plants evolved for local conditions that require minimal supplemental water once established, saving catchment resources.
